The entire information technology industry is talking about the cloud these days. Many businesses are asking the fundamental question, what is cloud computing? And most importantly, how can I use it to make my business more competitive and better serve my customers? If youre struggling to understand cloud computing technologies, this tutorial will give you the background youll need to make wise adoption choices.

Before cloud computing, if you wanted some computational power, you had three choices:

Each of these models has pros and cons. If you bought the equipment, you typically owned it through the full depreciation cycle of three to five years. That might have been the cheapest option, but it was the least flexible. You gained some long-term flexibility when you leased the equipment, but you paid more in trade and you still had all the operations costs. Typically, you wouldnt lease equipment for less than a 3 month time horizon, and probably at least a year, otherwise the overhead cost of receiving, configuring, and then returning the equipment would be too high. Finally, if you rented the server, you could get something with granular, monthly terms, but you were far more limited in the hardware choices and you couldnt deploy it in your own data center. The upside was you might be able to have it up and running in as few as 24 hours from the time you placed the order.

These models form a continuum: on one side we have the buy-and-own-everything model; on the other side we have the own-nothing model. In the middle, we have a wide variety of models where some things are owned and others not.

In the simplest sense, cloud computing is merely a refinement of the own-nothing model, with shorter timescales for resource rental, and greater flexibility for the customer as a result. The National Institute of Standards and Technology (NIST) has created what has become the canonical definition of cloud computing, publication 800-145, titled The NIST Definition of CloudComputing.

NIST defines cloud computing as having five essential characteristics:

The five essential cloud characteristics define a cloud in terms of abstract characteristics and resources. The characteristics apply equally well to a low-level infrastructure cloud as to a high level application cloud. The NIST definition goes on to organize clouds into three cloud computing service models:

Finally, the NIST definition outlines four different deployment models:

The NIST service and deployment models form a matrix:

So, you can have a private IaaS cloud or a public PaaS cloud. Hybrid clouds are shown in the matrix, but they really are a mix of the various public, private, and community cloud types. Thus, you could construct an interesting hybrid cloud environment from a combination of a private IaaS cloud based on VMware, a public IaaS cloud based on Amazon EC2, and a public PaaS cloud based on Google AppEngine.

Most larger enterprises will create a hybrid cloud environment of some sort, with multiple public and private clouds, and possibly a community cloud thrown into the mix. Some clouds will provide enhanced security; others will provide enhanced performance; still others will offer optimized pricing. Enterprises will then deploy application workloads within a suitable cloud to create an optimized outcome. Management software will help match application workloads to the right clouds given optimization goals and risk and compliance restrictions.

The cloud has become an ubiquitous term that even the average consumer is expected to understand. If you watch the commercials on television or read the tech trades, youd think that cloud computing was in full swing, turnkey ready, set, go.

The reality for many folks, however, is a little different. And while a proper implementation of a cloud-based solution will reduce costs, help make you much more adaptable to change, and raise the level of work you can accomplish, the truth is there is still a lot of fear about this new technology. As Henry Ford quipped, The only change people like is the one that jingles in their pocket. And in this instance, it couldnt be more true, particularly for government agencies who are struggling with how this fits into their IT agendas. So what is it that could be so scary about a cloud? The term alone denotes visions of a peaceful cumulus cloud floating against a clear blue sky.

Here are the top five reasons I believe why full adoption hasnt yet taken off, along with an explanation as to why it should, now:

These are real issues with real substance behind them. For most of them however, the government should be ready to move forward with the right planning and understanding of the Cloud, security, change management, and most importantly the drive to make the government more efficient and adaptable.

Introduction to Cloud Computing Questions and Answers What is Hypervisor in Cloud Computing and its types?, Are Type-1 Hypervisors better in performance than Type-2 Hypervisors and Why?, What are the characteristics on which a Cloud Computing Model should be selected for implementing and managing workload? Cloud Computing Architecture Questions and Answers Cloud Computing Architecture Questions - What is the use of defining cloud architecture?How does cloud architecture overcome the difficulties faced by traditional architecture?What are the advantages of cloud architecture?.... How does cloud computing provides on-demand functionality? Cloud computing is a metaphor used for internet. It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you. It provides an easy way to provide configurable resources by taking it from a shared pool. The pool consists of networks, servers, storage, applications and services. What is the difference between scalability and elasticity? Scalability is a characteristic of cloud computing through which increasing workload can be handled by increasing in proportion the amount of resource capacity. It allows the architecture to provide on demand resources if the requirement is being raised by the traffic. Whereas, elasticity is being one of the characteristic provide the concept of commissioning and decommissioning of large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources. What are the different layers of cloud computing? Cloud computing consists of 3 layers in the hierarchy and these are as follows: 1. Infrastructure as a Service (IaaS) provides cloud infrastructure in terms of hardware like memory, processor speed etc. 2. Platform as a Service (PaaS) provides cloud application platform for the developers. 3. Software as a Service (SaaS) provides cloud applications which are used by the user directly without installing anything on the system. The application remains on the cloud and it can be saved and edited in there only. What resources are provided by infrastructure as a service? Infrastructure as a Service provides physical and virtual resources that are used to build a cloud. Infrastructure deals with the complexities of maintaining and deploying of the services provided by this layer. The infrastructure here is the servers, storage and other hardware systems. How important is platform as a service? Platform as a Service is an important layer in cloud architecture. It is built on the infrastructure model, which provides resources like computers, storage and network. This layer includes organizing and operate the resources provided by the below layer. It is also responsible to provide complete virtualization of the infrastructure layer to make it look like a single server and keep it hidden from the outside world. What does software as a service provide? Software as Service is another layer of cloud computing, which provides cloud applications like google is doing, it is providing google docs for the user to save their documents on the cloud and create as well. It provides the applications to be created on fly without adding or installing any extra software component. It provides built in software to create wide varieties of applications and documents and share it with other people online. What are the different deployment models? Cloud computing supports many deployment models and they are as follows: Private Cloud Organizations choose to build there private cloud as to keep the strategic, operation and other reasons to themselves and they feel more secure to do it. It is a complete platform which is fully functional and can be owned, operated and restricted to only an organization or an industry. More organizations have moved to private clouds due to security concerns. Virtual private cloud is being used that operate by a hosting company.

Public Cloud These are the platforms which are public means open to the people for use and deployment. For example, google, amazon etc. They focus on a few layers like cloud application, infrastructure providing and providing platform markets.

Hybrid Clouds It is the combination of public and private cloud. It is the most robust approach to implement cloud architecture as it includes the functionalities and features of both the worlds. It allows organizations to create their own cloud and allow them to give the control over to someone else as well.

Low-Density Datacenters These datacenters are optimized to give high performance. In these datacenters the space constraint is being removed and there is an increased density. It has a drawback that with high density the heat issue also creeps in. These datacenters are very much suitable to develop the cloud infrastructure.

The modes of software as a service are defined as: 1. Simple multi-tenancy: in this each user has its own resources that are different from other users. It is an inefficient mode where the user has to put more time and money to add more infrastructure if the demand rises in less time to deliver. 2. Fine grain multi-tenancy: in this the functionality remains the same that the resources can be shared to many. But it is more efficient as the resources are shared not the data and permission within an application.

There are many levels of security which has to be provided within cloud environment such as: Identity management: it authorizes the application service or hardware component to be used by authorized users. Access control: permissions has to be provided to the users so that they can control the access of other users who are entering the in the cloud environment. Authorization and authentication: provision should be made to allow the authorized and authenticated people only to access and change the applications and data.
