Cloud Hosting

Serverless cloud addresses the shift in application architecture from a server-based architecture to an event-driven architecture by enabling a simpler, more cost-effective way to build and operate cloud-native applications.

In other words, applications are run virtually on any node within a distributed network, with limited amounts of resources allocated for these apps to perform their background operations. This way application code is executed on-demand as a response to triggers that app developers configure ahead of time.

Serverless functions are usually used to implement discrete units of application functionality, says Chanakya Levaka, VP-Global Sales & Marketing, Cloud4C Services.

One of the reasons why people are flocking towards using this type of application architecture is because they do not need to go through the steps of setting up and maintaining infrastructure when deploying their applications - with an increase in serverless-friendly use cases, this technology promises almost limitless potential, he adds.

Given the spectrum of benefits, serverless is leveraged across a wide range of applications, including customer relationship management (CRM); analytics and business intelligence; finance; Database, HR and streaming media applications; engineering and enterprise resource planning.

The key advantages of serverless cloud include:

Faster time to marketAccording to Girish Dhanakshirur, IBM Distinguished Engineer & CTO, IBM India Software Labs, serverless removes the burden of infrastructure management tasks from enterprise engineers allowing them to spend their time on developing richly featured applications while securing company and customer data.

Cost-effectiveCompared to all other service models, this generally is the most cost-effective approach as clients dont need to incur any idle expenses for the infra. The same is being paid only when specific functions in an application are invoked and resources are allocated.

With serverless, customers pay for the resources required to run their applications, and only when those applications are running and not during idle time. This provides companies with the scope to innovate freely, roll out new features and respond to the market faster leading to better customer experiences while being cost effective, avers Girish.

Offload Infrastructure and Operations management tasks

Application development is riddled with backend cloud infrastructure and operations tasks like provisioning, scheduling, scaling, patching and more. Serverless offloads these tasks to the cloud provider and tools which helps enterprise engineers to focus on higher value work, says Girish.

Chanakya adds serverless helps in freeing up developers time as all underlying server and infrastructure is managed by the cloud provider or Managed Services Provider and assigned to the client automatically only when a deployed app/software function is called to action.

As a result, developers can spend more time focusing on developing the code architecture and the frontend end-user experiences rather than worrying about tweaking, modifying the backend server and infra.
