Five reasons you should go for serverless

Serverless computing allows you to build and run applications and services without thinking about servers. Serverless applications don't require you to provision, scale, and manage any servers.Your cloud provider provides the infrastructure to run your code, which is called Backend as a service (BaaS)

 Most of the cloud providers have gone one more level further with another service called Function as a service (FaaS) or in general serverless function (eg: AWS Lambda, Azure functions etc). With FaaS all you need to do is develop your code and upload it to your cloud provider and they take care everything else like maintaining the infrastructure needed to run the code, scaling up, scaling down, health check, logging etc. FaaS is using container model to run the application, which means it will scale up or scale down automatically depends on the load.
Five you may want to go for serverless computing, 

1.    Right product at right time: If you are not moving your product to market at a higher pace then your rival will conquer the market. It will literally take few hours or maybe minutes to push your code to live without spending weeks and months on setting up a server to push your product to the market

2.    Expand your customers with no change: - Think you created the application with ten thousand customers in mind but you started getting one million hits. If your application is running in your dedicated host outside cloud then I bet your application will crash because your app server cannot scale on its own. But with serverless computing, you don’t need to worry about the load, let it be ten thousand or one million you serverless function will scale up automatically because it is using container model behind the scene.

3.   Pay as you go:   Why do you want to spend money if your application is idle? If you have a dedicated host then it will still consume system resources even if your application is not in use, which is a waste of money. With serverless computing, you pay only if your application is in usage else you don’t need to pay a single penny.

4. Best fit with highly scalable microservice: Serverless functions fits best with microservice architecture. Scale up or scale down individual microservice will happen automatically. As mentioned before FaaS is using container model. Whenever there is a high load on a specific service then it will automatically create more instance of that specific service and destroy the instance when low load.

5. Just concentrate on the code: As you don’t need to spend time and effort for anything else other than just to develop the application you can completely concentrate on a better quality code, which apparently makes a better customer base and grow your business.
