Developers today prefer serverless computing due to the many benefits it offers. A study done on software firms showed that nearly 40% of respondent companies used serverless computing in some form. This highlights the popularity of serverless computing today.

What is serverless computing?

Serverless computing is where backend services are offered to developers on ‘as used’ basis. What this means is the developers don’t have to worry about the infrastructure or server. The back end includes processing, security aspects, and data file storage.

In serverless computing, all these are dormant and are activated only when the user needs them. At that time, space is allotted by executing a code. The code once again becomes dormant once the event is concluded. This is very convenient for development since developers need not worry about servers, bandwidth, and other such considerations.

Any developer who wanted to build an app had to have a server or hardware. This would not only be expensive, but also be inconvenient since the server would need to be maintaining on an ongoing basis. Serverless computing now allows anyone to develop web apps or software easily without having to get a server.

It must be noted that serverless computing does not mean there is no server. The vendor would usually use a cloud server. The serverless concept is for the user or developer who does not have to worry about the server.

Serverless computing in software development: Benefits

  1. The principal benefit of serverless computing is the savings in costs. There is no need to setup hardware infrastructure. Users need to pay only for the space they use, and the CPU time used for processing. There is no need to pay for unused space, which is what happen when you have a server.
  2. Flexibility is a key benefit offered. A development firm can scale as they grow, and the process happens seamlessly. The vendor offering serverless computing services handles the scaling without developers having to intervene.
  3. The turnaround time can improve when serverless computing is used. Time to market can be significantly brought down. Code can be added or modified on piecemeal basis avoiding a complicated deployment process.
  4. Developers can focus on their core work without having to worry about back-end architecture. This helps to improve their productivity and enhance accuracy.
  5. When the code is run, it is run on a server close to the user. This reduces latency and thus ensures better speed and convenience for the end user.
