What Is Cloud Computing? | The Basics of Digital Outsourcing
Cloud computing: the synergistic boardroom buzzword that you still pretend to know about.
Luckily, its a pretty simple idea, technically demanding, but simple none-the-less. On paper, cloud computing is just another way for humans to share resources and increase production.
When you use cloud computing you are essentially outsourcing a computer-related task the same way a company may choose to outsource a task like accounting, manufacturing, customer support, or human resources to name a few.
Cloud computing instead outsources tasks such as data storage, web server hosting, Bitcoin mining (warning), and software management among others.
In order to really understand the perks of cloud computing lets paint a picture of two similar e-commerce businesses. Both businesses are selling a product and using a website as their primary sales portal. Both are also new businesses with a small customer base but can reasonably expect to increase traffic to their e-commerce store in the future.
The first business, lets call it Tods Toys, is running their website on locally installed servers and hosts all their own data. Not to worry though, Tods Toys has an excellent CTO running the operation and has the current hardware/software stack purring along.
The second business, this one named Guptas Guitars, is a little more bespoke and decided to instead opt for hosting their website on a cloud server. Guptas Guitars also has a capable CTO monitoring the online stores health.
In their beginning stages, Tods Toys and Guptas Guitars are seeing similar traffic rate to their stores. However, Tods Toys is noticing a higher operating cost coming from their web servers; they have more than they currently need. The toy store doesnt mind though, as they expect traffic to increase into the server capacity they have.
Guptas Guitars, on the other hand, paid for their server use much more ad hoc. Their server access scales with traffic, so the guitar store hasnt noticed any waste. In fact, while their traffic volume was low so was their cost for using the cloud servers. Naturally, they threw a guitar-fueled pizza party with their savings!
As predicted, both online stores begin to see a precipitous uptick in volume and sales. Guptas Guitars rejoices and probably throws another pizza party. Tods Toys, on the other hand, doesnt have as long to celebrate.
The online toy store quickly pivots to scaling their server hardware as demand on their self-hosted platform outpaces their capacity. Potential customers are served 404 error messages instead of the spectacular toys that Tods offers. *Sad face*
You can see, cloud computing let Guptas Guitars outsource their server needs and as a result, focus on other aspects of their business.
A ridiculously oversimplified example but the key point is there.
Cloud computing for businesses, as in the above example, is typically referred to as enterprise cloud computing. This differs from other cloud computing services that may be more consumer-facing like Google Drive or MegaUpload (R.I.P.).
In either case, cloud computing is actually a stack of three generalized cloud provided services. At the base of the stack is the infrastructure cloud services also known as infrastructure as a service (IaaS). The middle layer is the developers layer known as platform as a service (PaaS). The top and the most visible layer is the software as a service (SaaS) layer also known as the application layer.
IaaS (infrastructure as a service)is the foundational layer made up of all the necessary hardware that makes the digital cloud tick. Despite the reference to watery vapor above us, cloud computing is made of some serious hardware, real, tangible, and often loud. IaaS is all of the physical hardware that stores and moves our zeros and ones.
Examples of IaaS providers: CloudSigma, Digital Ocean, Linode, Cisco Cloud Infrastructure Services, Microsoft Azure, Citrix Workspace Cloud
PaaS (platform as a service)isthe next layer up, where the developers and programmers get involved. In this middle layer, IaaS providers lease chunks of cloud hardware to developers and programmers pre-installed with developer tools like Apache or MySQL. This middle layer is where IaaS providers and software developers overlap.
Examples of PaaS providers: Oracle Cloud, Salesforce Platform, Google Cloud Platform, Amazon Web Services
SaaS (software as a service)isthe topmost and more familiar layer of the cloud stack. This is where applications and software are, and we see some familiar names like Spotify, Adobe Creative Cloud, Google Play Store, Storj, and Dropbox to name a few. The SaaS layer is essentially where cloud services become user-friendly for consumers and businesses alike.
Examples of SaaS providers: Slack, WordPress, Trello, Mailchimp, InVision, Zoom, Buffer, Contently, Netflix
The basic cloud computing stack
Each layer of the cloud service stack enables the one before it. In short, you can think of the three layers like this: first, you need hardware. Second, you need a platform to build from. Third, you need applications so people can use the hardware.
While each use case will have much more granular pros and cons, the following are a few general benefits and drawbacks of cloud computing.
The next evolution to the cloud service stack should be one that can support a distributed infrastructure layer. By fragmenting smaller pieces of a sizable cloud infrastructure, we might be able to shift the centralization of hardware and alleviate that security vector.
If only there were a system of organization that could incentivize hardware providers to come together in a distributed method in order to provide cloud-like services to platform and software developers. If only.

Background
Whats all the fluff about cloud computing? There are plenty of reasons its the most talked-about trend in technology. Starting with the fact that it helps reduce the up-front capital needed to build IT infrastructure and develop software. Cloud services are so appealing that the total market is expected to nearly triple from 2010 to 2016. (Yep, you read that right.)
Of course, technology companies have clamored to add cloud computing to their repertoires, leading to lots of M&A activity. Software and Internet deals represented 57% of transactions closed in 2012, a figure that has grown steadily over the last two years. All of which leaves the cloud looking like a lot more than a passing storm.
We identified US-listed stocks and American Depository Receipts of companies that are engaged in activities relevant to this watchlist's theme. We then filtered out companies that have a share price of less than .00 or a market capitalization less than 00 million, and excluded illiquid stocks by screening companies for liquidity i.e. average bid-ask spreads, dollar volume traded etc. Finally the proprietary Motif Optimization Engine determined the constituent stocks. Learn more about how we select our watchlists.
Motif is an online brokerage built on thematic portfolios of up to 30 stocks and ETFs. Founded in 2010 by Hardeep Walia, Motif combines complex proprietary algorithms with skilled advisers to develop these thematic portfolios. Learn more about our team.
First, we determined each company's percentage of total revenue derived from this watchlist's theme. Second, we applied a pure-play factor to give greater relative weight to companies that derive a higher percentage of their revenue from this theme. Finally, we weighted each company by its market capitalization adjusted for revenue exposure to the theme.

Cloud Computing Explained by Common Craft (VIDEO)
Computers used to work alone, inside a home or business. But thanks to the Internet, we can now use the power of computers at a completely different location - what we call "in the cloud".
To start, meet Lucy from Lucy's Lilies, a new florist. She is concerned about how to manage flower deliveries. Right now she's responsible for hiring drivers and keeping the vans running. But this scenario makes her nervous.
She's a florist, not a mechanic - delivery is a distraction.And she's on a budget - maintaining her own deliveries costs a lot.Plus, it's hard to know how many vans she'll need. Her business suffers when deliveries can't keep up.
Then she learned about a new kind of delivery company that has an unlimited fleet of drivers and vans that she can use on an as-needed basis - and she only pay for what she uses. Now she can depend on another company to handle the deliveries.
A few years later, her business savvy paid off. She now has a network of florists and new problems.She has websites, servers and databases that all have to be maintained at headquarters. Its a huge expense, and a big worry. Her business is constantly running out of storage space and fixing broken servers.
Then she learned about cloud computing, which works a lot like her deliveries. Instead of managing important technology on-site, she can depend on a new kind of company to help take away the pain.
They have all the computing power she needs and it's all secure, backed up at another location and accessible through the Web - what people call "in the cloud."
This means she can depend on a cloud company's computers to help her business run and focus her energy on fantastic flowers.
But that's not all. Cloud computing means computers don't have to limit her business. Because Cloud companies have nearly unlimited storage and resources, she can grow without worry. And because the servers are normally backed up in multiple locations, her information is safe.
But what she really loves is only paying for what she uses. If business is slow, her computing costs can go down too.
Cloud Computing also means she can use new kinds of services that live in the cloud and are only accessible through the web.
When she needs a new billing system, she has a choice: installing and supporting one on-site, or using a product that lives in the cloud and works using her web browser.
From email, to word processing or photo sharing - cloud computing also works for you and me. We can use products that live in the cloud, are always backed up, accessible from any Internet connection, and safe from spilled coffee.
Cloud computing means we have new choices. Businesses and individuals can spend less time worrying about technology and focus on what matters.

Cloud Computing Trends: 2017 State of the Cloud Survey
Update: 2018 cloud computing trends from the latest RightScale State of the Cloud Survey are now available.
In January 2017, RightScale conducted its sixth annual State of the Cloud Survey of the latest cloud computing trends, with a focus on infrastructure-as-a-service. In 2017, we see several new themes emerging: anarrowing race among public cloud providers,decrease in private cloud adoption, a renewed focus among enterprises on optimizing cloud costs, and strong growth in Docker.
This is the largest survey on the use of cloud infrastructure thatis focused on cloud buyers and users, as opposed to cloud vendors. Their answers provide a comprehensive perspective on the state of the cloud today.
The survey asked 1,002 IT professionals about their adoption of cloud infrastructure and related technologies. Forty-eight percent of the respondents represented enterprises with more than 1,000 employees. The margin of error is 3.07 percent.
We highlight several key findings from the survey in this blog post. For the complete survey results, download the RightScale 2017 State of the Cloud Report.
Cloud Computing Trends: Key Findings
In the twelve months since the last State of the Cloud Survey, weve seen private cloud adoption fall slightly. The percent of respondents now adopting private cloud is 72 percent, down from 77 percent last year.As a result, use of hybrid cloud environments has fallen to 67 percent from 71percent last year. In total, 95 percent of respondents are now using cloud.
The percentage of enterprises that have a strategy to use multiple clouds grew to 85 percent (vs. 82 percent in 2016) with 58 percent planning on hybrid (vs. 55 percent in 2016). There was also an increase in the number of enterprises planning for multiple public clouds (up from 16 percent to 20 percent) and a concurrent decrease in those planning for multiple private clouds (down from 11 percent to 7 percent).
Companies that use public cloud are already running applications in an average of 1.8 public clouds and experimenting with another 1.8 public clouds. While fewer companies are using private clouds, those that do use more, running applications in an average of 2.3 private clouds and experimenting with an additional 2.1 private clouds.
Companies now run 79 percent of workloads in cloud, with 41 percent of workloads in public cloud and 38 percent in private cloud. Its important to note that the workloads running in private cloud may include workloads running in existing virtualized environments or bare-metal environments that have been cloudified.
Enterprises run 75 percent of workloads in cloud with more in private cloud (43 percent) vs. public cloud (32 percent). SMBs run 83 percent of workloads in cloud with more in public cloud (50 percent) vs. private cloud (33 percent).
This year we saw a strong shift toward centralization, with more central IT teams taking a broader view of their role in cloud. They see a role for themselves in selecting public clouds (65 percent), deciding/advising on which apps to move to cloud (63 percent), and selecting private clouds (63 percent).
However, there is now a significant gap between the view of central IT and that of the business units they support. Respondents in business units are less likely to delegate authority to central IT for selecting public clouds (41 percent), deciding/advising on which apps to move to cloud (45 percent), and selecting private clouds (38 percent).
In 2017, cloud challenges declined across the board with the exception of governance/control, which remained flat. This year expertise, security, and spend were all tied for the top challenge with 25 percent of respondents citing each as a significant challenge.
Lack of resources/expertise, the #1 cloud challenge in 2016, was less of a challenge in 2017 with only 25 percent citing it as a major concern, down significantly from 32 percent in 2016. Concerns about security fell to 25 percent vs. 29 percent last year. Managing cloud spend fell only slightly from 26 to 25 percent.
Even as managing cloud costs becomes a top challenge, cloud users underestimate the amount of wasted cloud spend. Respondents estimate 30 percent waste, while RightScale has measured actual waste between 30 and 45 percent.
This increased concern about costs has made optimizing cloud costs the top initiative for 2017 across all cloud users (53 percent) and especially in mature cloud users (64 percent).
As part of adopting DevOps processes, companies often choose to implement new tools that allow them to standardize and automate deployment and configuration of servers and applications. These tools include configuration management tools (such as Chef, Puppet, and Ansible) and, more recently, container technologies, such as Docker and container orchestration and scheduling tools such as Kubernetes, Swarm, and Mesosphere.
The meteoric rise in the use of containers now makes Docker the top DevOps tool among those included in our survey. Overall Docker adoption surged to 35 percent, taking the lead over Chef and Puppet at 28 percent each. (Note that we did not ask about continuous integration tools such as Jenkins, Travis, and others.)
The 2017 State of the Cloud Survey reveals that although AWS continues to lead in public cloud adoption (57 percent of respondents currently run applications in AWS), this number has stayed flat since both 2016 and 2015. It is important to note that while the percentage of companies running at least one application in AWS is flat, the number of applications and VMs they are running is increasing, thereby driving increased revenue for AWS.
In contrast, over the last year, weve seen significant growth in the percentage of respondents running applications in Azure and Google, the #2 and #3 public cloud providers. Overall Azure adoption grew from 20 to 34 percent of respondents to reduce the AWS lead, with Azure now reaching 60 percent of the market penetration of AWS. Google also increased adoption from 10 to 15 percent.
The public cloud adoption numbers above indicate the number of respondents who are running any workloads in a particular cloud. However, it is also important to look at the number of workloads or VMs that are running in each cloud. The chart below shows the number of VMs being run.
So although AWS adoption is flat, it shows the largest footprint for public clouds with 8 percent running more than 1,000 VMs and 28 percent running more than 100 VMs. In comparison, Azure only has 3 percent running more than 1,000 VMs and and 13 percent running more than 100 VMs.
In contrast to last years survey when we saw private cloud adoption grow, the 2017 survey shows that adoption of private cloud is flattening across all providers. Across all sizes of organizations, VMware vSphere continues to lead with 42 percent adoption, slightly below last year (44 percent). OpenStack (20 percent) and VMware vCloud Suite (19 percent) were also flat in growth, with OpenStack barely eking into the #2 slot. Microsoft Azure Pack/Stack was the only private cloud technology to show significant growth, up from 9 percent to 14 percent. Microsoft System Center showed 3 percent growth, which is right at the 3 percent margin of error.
The 2017 State of the Cloud Survey shows that while hybrid cloud remains the preferred enterprise strategy, public cloud adoption is growing while private cloud adoption flattened and fewer companies are prioritizing building a private cloud. This was a change from last years survey, where we saw strong gains in private cloud use.
AWS leads in public cloud adoption despite staying flat for the last two years in the number of respondents using it. However, respondents are running more VMs in AWS than in other public clouds, which explains the AWS lead in revenue. Azure made strong gains in adoption in this years survey, closing the lead on AWS. Google also made gains and still remains in the #3 position.
Enterprise central IT teams are taking a stronger role in cloud adoption. However, business units seem reluctant to give up authority. Cloud governance continues to progress, which will serve to help increase alignment between central IT and the business units they support.
With increasing maturity of both cloud users and cloud providers, we are seeing an across-the-board reduction in cloud challenges. Unlike last year when concern about resources and expertise was the most widespread (32 percent of users), this year security, spend, and expertise tied for the largest concern, albeit with only 25 percent of users expressing concern about each.
As adoption grows, cloud bills and cost concerns are also growing. As a result, the most cited challenge among mature cloud users was managing cloud costs. Most organizations, however, continue to underestimate the level of waste in cloud spend (30 percent) when compared to actual waste between 30 and 45 percent measured by RightScale. Although only a minority of cloud users have taken action to reduce waste, they are now turning their focus to this issue, making it the top initiative for 2017, followed closely by migrating more workloads to cloud.
The use of DevOps practices and tools continues to increase, with enterprises moving beyond piecemeal adoption to company-wide DevOps programs. This year Docker surged to become the top DevOps tool in the survey, seemingly at the expense of configuration management tools such as Puppet and Chef, which showed declines in adoption.

Cloud Computing provides us means of accessing the applications as utilities over the Internet. It allows us to create, configure, and customize the applications online.
The termCloudrefers to aNetworkorInternet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over public and private networks, i.e., WAN, LAN or VPN.
Applications such ase-mail, web conferencing, customer relationship management (CRM) execute on cloud.
Cloud Computingrefers tomanipulating, configuring,andaccessingthe hardware and software resources remotely. It offers online data storage, infrastructure, and application.
Cloud computing offers platform independency, as the software is not required to be installed locally on the PC. Hence, the Cloud Computing is making our business applicationsmobileandcollaborative.
There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing:
Deployment models define the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of the four types of access: Public, Private, Hybrid, and Community.
Thepublic cloudallows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness.
Theprivate cloudallows systems and services to be accessible within an organization. It is more secured because of its private nature.
Thecommunity cloudallows systems and services to be accessible by a group of organizations.
Thehybrid cloudis a mixture of public and private cloud, in which the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
Cloud computing is based on service models. These are categorized into three basic service models which are -
Anything-as-a-Service (XaaS) is yet another service model, which includes Network-as-a-Service, Business-as-a-Service, Identity-as-a-Service, Database-as-a-ServiceorStrategy-as-a-Service.
TheInfrastructure-as-a-Service (IaaS)is the most basic level of service. Each of the service models inherit the security and management mechanism from the underlying model, as shown in the following diagram:
IaaSprovides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc.
PaaS provides the runtime environment for applications, development and deployment tools, etc.
SaaSmodel allows to use software applications as a service to end-users.
The concept ofCloud Computingcame into existence in the year 1950 with implementation of mainframe computers, accessible viathin/static clients. Since then, cloud computing has been evolved from static clients to dynamic ones and from software to services. The following diagram explains the evolution of cloud computing:
Cloud Computing has numerous advantages. Some of them are listed below -
One can access applications as utilities, over the Internet.
One can manipulate and configure the applications online at any time.
It does not require to install a software to access or manipulate cloud application.
Cloud Computing offers online development and deployment tools, programming runtime environment throughPaaS model.
Cloud resources are available over the network in a manner that provide platform independent access to any type of clients.
Cloud Computing offerson-demand self-service. The resources can be used without interaction with cloud service provider.
Cloud Computing is highly cost effective because it operates at high efficiency with optimum utilization. It just requires an Internet connection
Cloud Computing offers load balancing that makes it more reliable.
Although cloud Computing is a promising innovation with various benefits in the world of computing, it comes with risks. Some of them are discussed below:
It is the biggest concern about cloud computing. Since data management and infrastructure management in cloud is provided by third-party, it is always a risk to handover the sensitive information to cloud service providers.
Although the cloud computing vendors ensure highly secured password protected accounts, any sign of security breach may result in loss of customers and businesses.
It is very difficult for the customers to switch from oneCloud Service Provider (CSP)to another. It results in dependency on a particular CSP for service.
This risk involves the failure of isolation mechanism that separates storage, memory, and routing between the different tenants.
In case of public cloud provider, the customer management interfaces are accessible through the Internet.
It is possible that the data requested for deletion may not get deleted. It happens because either of the following reasons
There are four key characteristics of cloud computing. They are shown in the following diagram:
Cloud Computing allows the users to use web services and resources on demand. One can logon to a website at any time and use them.
Since cloud computing is completely web based, it can be accessed from anywhere and at any time.
Cloud computing allows multiple tenants to share a pool of resources. One can share single physical instance of hardware, database and basic infrastructure.
It is very easy to scale the resources vertically or horizontally at any time. Scaling of resources means the ability of resources to deal with increasing or decreasing demand.
The resources being used by customers at any given point of time are automatically monitored.
In this service cloud provider controls and monitors all the aspects of cloud service. Resource optimization, billing, and capacity planning etc. depend on it.
15 Top Cloud Computing Service Provider Companies
Introduction to Cloud Computing Services:
Earlier we used to store our data in hard drives on a computer. Cloud Computing services have replaced such hard drive technology. Cloud Computing service is nothing but providing services like Storage, Databases, Servers, networking, the softwares etc through the Internet.
Few Companies offer such computing services, hence named as Cloud Computing Providers/ Companies. They charge its users for utilizing such services and the charges are based on their usage of services.
In our daily routine we use this cloud service without our notice like web-based email service, watching movies through the internet, editing documents, storing pictures etc uses cloud computing on the back-end.
Using such cloud technology we can design and create new applications, store and recover data, hosting the websites etc.
Generally, cloud computing services are categorized into three types.
1) Infrastructure as a Service (IaaS): This service provides the infrastructure like Servers, Operating Systems, Virtual Machines, Networks, and Storage etc on rent basis.
Eg: Amazon Web Service, Microsoft Azure
2) Platform as a Service (PaaS): This service is used in developing, testing and maintaining of software. PaaS is same as IaaS but also provides the additional tools like DBMS, BI services etc.
Eg: Apprenda, Red Hat OpenShift
3) Software as a Service (SaaS): This service makes the users connect to the applications through the Internet on a subscription basis.
Eg: Google Applications, Salesforce

Examples of cloud computing include Software as a Service, Platform as a Service, and Infrastructure as a Service. Generally, cloud computing services are run outside the walls of the customer organization, on a vendor's infrastructure with vendor maintenance.
Although cloud-like services can be internal (e.g., IU's Intelligent Infrastructure), this document refers exclusively to cloud services provided by third-party vendors over a network connection where at least part of the service resides outside the institution, regardless of whether those services are offered freely to the public or privately to paying or registered users.
Cloud computing represents an externalization of information technology applications and infrastructure beyond an organization's data center walls. In the university context, cloud computing may be thought of as extra-campus or above-campus computing.
Cloud services are often available "on demand," and utilize an infrastructure shared by the vendor's customers. While some offer a flat fee model or consumption-based pricing, other cloud services are offered at no cost.
Within the university, the confidentiality, integrity, availability, use control, and accountability of institutional data and services are expected to be ensured by a suite of physical, technical, and administrative safeguards proportional to the sensitivity and criticality (i.e., risk) of those information assets and services.
These safeguards help protect the reputation of the university and reduce institutional exposure to legal and compliance risks. Much of the challenge in approaching cloud computing involves determining whether a service vendor has adequate safeguards in place commensurate with the value and risk associated with assets and services involved.
Once the high-level challenges are understood, the next step is to consider the risks and determine whether or how to appropriately mitigate those risks in the context of the proposed information and/or service.
The above factors should not be taken to suggest that cloud computing has no potential benefits; but rather that the benefits must be balanced with the risks involved when evaluating the use of cloud computing services.
Cloud computing services are similar to traditional outsourcing and can be approached analogously while accounting for their unique risks/benefits. The following recommendations and strategies are intended to assist units in their approach to evaluating the prudence and feasibility of leveraging cloud services.

Learn Cloud Computing Tutorial – javatpoint
Cloud Computing tutorial provides basic and advanced concepts of Cloud Computing. Our Cloud Computing tutorial is designed for beginners and professionals.
Cloud Computing Tutorial with high end solution of IT infrastructure. Cloud computing is a virtualization based technology that reduces the cost of IT infrastructure. It provides a solution of IT infrastructure in low cost.
In this cloud tutorial, you will learn basics and advanced topics of cloud which is developed for beginners and professionals.
Cloud computing means on demand delivery of IT resources via the internet with pay-as-you-go pricing. It provides a solution of IT infrastructure in low cost.
Actually, Small as well as some large IT companies follows the traditional methods to provide the IT infrastructure. That means for any IT company, we need a Server Room that is the basic need of IT companies.
In that server room, there should be a database server, mail server, networking, firewalls, routers, modem, switches, QPS (Query Per Second means how much queries or load will be handled by the server) , configurable system, high net speed and the maintenance engineers.
To establish such IT infrastructure, we need to spend lots of money. To overcome all these problems and to reduce the IT infrastructure cost, Cloud Computing comes into existence.
The characteristics of cloud computing are given below:
The cloud works in the distributed computing environment. It shares resources among users and works very fast.
Availability of servers is high and more reliable, because chances of infrastructure failure are minimal.
Means "on-demand" provisioning of resources on a large scale, without having engineers for peak loads.
With the help of cloud computing, multiple users and applications can work more efficiently with cost reductions by sharing common infrastructure.
Cloud computing enables the users to access systems using a web browser regardless of their location or what device they use e.g. PC, mobile phone etc. As infrastructure is off-site (typically provided by a third-party) and accessed via the Internet, users can connect from anywhere.
Maintenance of cloud computing applications is easier, since they do not need to be installed on each user's computer and can be accessed from different places. So, it reduces the cost also.
By using cloud computing, the cost will be reduced because to take the services of cloud computing, IT company need not to set its own infrastructure and pay-as-per usage of resources.
Application Programming Interfaces (APIs) are provided to the users so that they can access services on the cloud by using these APIs and pay the charges as per the usage of services.

Cloud Computing | The MIT Press
Why cloud computing represents a paradigm shift for business, and how business users can best take advantage of cloud services.
Most of the information available on cloud computing is either highly technical, with details that are irrelevant to non-technologists, or pure marketing hype, in which the cloud is simply a selling point. This book, however, explains the cloud from the user's viewpointthe business user's in particular. Nayan Ruparelia explains what the cloud is, when to use it (and when not to), how to select a cloud service, how to integrate it with other technologies, and what the best practices are for using cloud computing.
Cutting through the hype, Ruparelia cites the simple and basic definition of cloud computing from the National Institute of Science and Technology: a model enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. Thus with cloud computing, businesses can harness information technology resources usually available only to large enterprises. And this, Ruparelia demonstrates, represents a paradigm shift for business. It will ease funding for startups, alter business plans, and allow big businesses greater agility.
Ruparelia discusses the key issues for any organization considering cloud computing: service level agreements, business service delivery and consumption, finance, legal jurisdiction, security, and social responsibility.
