Have you heard about serverless architecture ? Well it doesn’t mean there is no server for your code. Technically serverless is a framework or architecture to save the expensive server costs. Lets see how it does.

As we all know, a server is a computer where an application is deployed. Most developers deploy their code on a remote server where someone else takes care of hardware and software maintenance. That is what most of us are doing. At this point, servers could be expensive even for small projects, it can be a big impact. Your server must be running 24 hours a day to be able to handle requests at any time.

As I said in above, serverless does not mean there is no server. The serverless infrastructure runs on someone else’s managed server. This means you don’t have to worry about maintenance, network security, or uptime. And we only have to pay when our code is being executed which means it will only charged for the amount of time and memory used.

We all know horizontal & vertical scaling when it comes to handling the traffic from users. Both of the options can be expensive, isn’t it ? Well in serverless, you can scale to millions of requests. No new infrastructure required! There is no need to add new servers.

Well, that is all for now. You can try it out serverless in below services.

Although it is powerful to scale up your application with more affordable cost, there might be some drawback also. For example, caching and debugging can be tricky. And of course, you have to learn the new tools to configure it which can be tricky as well.
