Serverless Architecture | ATeam Soft Solutions
App development keeps evolving and this evolution does not seem to have an end. Trends like cloud computing have helped developers to meet the new expectations of businesses, by building applications in a much faster and productive way. But in recent years, terms – “Serverless application” and “Serverless Architect” – have seen an increasing momentum, leading us to the concept of Serverless computing. Despite being a relatively new capability, the popularity that Serverless has gained in the IT industry makes it the next step in the app development. Cloud apps are shifting to Serverless world, but why? There’s a simple reason behind this hype – No infrastructure management. Benefits like less workload, less time to market, reliability, improved efficiency and affordability, Serverless architecture has managed to deliver what technologists desire. The role of Serverless computing in IT will only expand in the upcoming years. Therefore, if you still haven’t caught on with the technology, chances are you will soon have to update your imagination.
Since its launch in 2014, Serverless architecture has refined the ways of app development. According to RightScale’s 2018 State of the Cloud report, with the annual growth of 75%, Serverless is the fastest-growing cloud service model, at the moment. That’s not surprising, given the fact that the technology lowers costs, reduces operational complexity, and increases DevOps efficiencies. Furthermore, statistics show that by 2021, the market size of Serverless computing is estimated to grow to 7.72 Billion!
Stefan Bergstein, Chief Software Architect at Micro Focus, said the wheels were in motion for serverless adoption.
However, what really is Serverless Computing? What is a serverless application? How does serverless web application work? What potential and benefits does it hold for developers and business enterprises? And why is Serverless Architecture the right choice for you?
We will be tackling all these questions in this article. Let’s break it down with a step-by-step guide and get a better understanding of the concept.
What is Serverless Architecture?
The word “Serverless” does not mean “no servers”, in fact servers are an integral part of the concept. Serverless computing is an execution model of Cloud computing, where the need to manage infrastructure is eliminated. Meaning, the developers do not have to worry about server management, scaling or provisioning when deploying code. They only focus on building the application while the back-end system that supports the app i.e. server, is managed by cloud provider and the billing is done only for the time the code runs or requests / events are processed. This allows developers to reduce maintenance cost and increase productivity.
