Why Serverless Architecture Stands out as The Game Changer

If you have been dozing under a rock for last few years, Serverless Architecture is your next big step to take in the journey from physical hosting to deploying software or code on the cloud. Following a logical progression from monoliths to microservices, serverless architecture sees the big future through fine-grained, event-driven functions.

 

For some might relate serverless with microservices-based applications but, it is a further breakdown of applications. For every action you make, there is a function focused on an even smaller scope of application logic than that of microservices.

 

Serverless compute is a computational model where no dedicated servers or VMs needs to be up and running on your premises 24×7. It is the Cloud provider you choose, that takes care of everything; from VMs to the underlying infrastructure, orchestration, and automation required to support any type of applications and run a voluminous number of events.

 

The request comes in via an API gateway, automatically triggers code or function in response to a set of pre-defined events and finds a virtual server for execution. The managed server then executes the function you requested for, returns the result via that API and decommission as soon as the task is successfully accomplished.

 

AWS Serverless Architecture; Workflow

 

Since the unit of deployment in serverless computing is an autonomous function, the platform is also called as Function as a Service (FaaS).

And when it comes to harnessing cutting-edge technologies like mobility, IoT, or real-time big data, serverless architecture sure is a huge advantage.

 

Why Serverless Architecture?

 

Believe It or Not | Tapping the power of serverless, enterprises achieve the flexibility to scale as required without any fuss of running and managing armada of servers. You pay only for what you use and for the fraction of time taken to run your functions. There is no cost associated with the idle computing time.

Talking of serverless computing, we cannot miss Lambda, AWS pulled out of its hat for running and managing back-end applications in the cloud, back in 2014.

 

The auto scaling power, high availability and cost efficiency of Lambda are giving birth to a whole new range of innovative applications putting the scale, ease of development, and deployment in the hands of developers.

 

Bye-Line | “Serverless” or “serverless computing” doesn’t mean that your code or functions will be running in the air or that there are no servers involved. It is simply a paradigm shift from buying and managing dedicated servers on your own to acquiring a third-party platform that runs all your functions on their completely managed servers.

 

A serverless approach lets developers shift their focus from server and operational levels to the development level.
