“Serverless” is by now the most used and popular technology. It has two different parts to its application architecture. The first part is the ‘back-end as a service’ commonly known as BaaS. This particularly applies to applications that have their back-end on the cloud. A third party maintains this aspect of serverless computing. This is mostly because front-ends are heavy to solely exist on the serverless architecture. Examples of such rich and complex UI are mobile applications, web applications etc. The second part is ‘function as a service’ or FaaS. It has an application that makes use of event triggers to run certain parts of the code.
Serverless computing has an end number of benefits. The architecture of serverless evokes functions right on demand. This comes in handy as it provides flexibility to applications on the server side. In certain cases, your application may be such that a serverless computing approach might be perfect for it. If an app has to be spin up really fast, serverless lets you do that.
Usually, deployment of an app takes weeks and can go even up to months. However, if you are using serverless architecture, you can do it in a matter of days. This is because using serverless architecture is not something to worry about. The developer can concentrate on coding.
Another major benefit is when it comes to scalability. Scalability is automatic when it comes to serverless. You do not have to worry about any additional provisions. It is also very budget friendly. This is mainly because you are outsourcing a great chunk of work including management of servers, databases etc.
The actual production cost is also less because the computing power and human resources employed is less. With serverless, you do not have to make a server from scratch. The infrastructure part of it is already taken care of. Server-side code is very important so you can allocate your resources and logic towards that.
Sometimes the load to a website might peak unexpectedly. A good server will be able to handle that. If that is your aim then you should choose serverless. It helps you handle all kinds of traffic. The application is such that it can automatically change depending on the traffic. If your app experiences a growth spurge suddenly, it will be easy to make changes to accommodate this. Even if there is no heavy load, it will not be harmful as the cost you will be paying will be the same.
Compared to traditional servers, serverless makes the implementation of an app easier. Thus, you get more time to innovate. This also helps you to move on to your next project as you easily get tangible results. Many companies provide you with serverless computing services. However, not all of them can be trusted. If not done properly it might lead to a collapse of your application and you might have to restructure it again.
