Why should you build a serverless solution?
Serverless computing allows you to build and run applications and services without thinking about the servers. Serverless applications do not demand that you provide, scale and maintain the servers, but instead, everything needed to run and scale the application for high availability and reliability is simply handled for you.
No server management
There is no longer a need to provision or administrate any servers. No software or runtime needs to be installed, maintained or administrated. Less work, but more efficient.
Your application will scale automatically or by controlling the parameters that characterize your application, that could be a memory or another capacity, instead of affecting entire servers.
Serverless applications have built-in availability and field tolerance. You do not need to build architecture for this as the AWS services that run the applications provide it as standard.
No expensive redundant capacity
Don’t pay for oversized servers that don’t work! If your code is not running – then you do not pay anything. So, it’s over with pre- and over-commissioning of servers “for security reasons”. Much more cost-efficient!
