The term serverless is a misnomer. It does not literally mean that there are no servers. Serverless app development is a cloud-based architecture used for app development where the cloud provider has the responsibility of allocating and provisioning servers. A cloud provider completely manages these servers. The traditional need of an ‘always on’ server component is done away with. Following are some of the benefits of serverless app development.
- Pay Per Use
One of the main advantages of using serverless app development is the pricing. The developers and users will only be charged for what they actually use. The code can thus run automatically. On the other hand, in traditional server architecture, a predetermined server capacity has to be bought and paid for irrespective of whether it is used or not.
- Easily Deploy Your App
In order to release a working model of your application, there is no need to do any backend configuration. Updating becomes easy and a product can be easily released. It serves quick functionalities like updating, patching, fixing etc. New features can be easily added to the application. Additionally, one does not have to make changes to the entire application to bring changes to a single function.
- Freedom from Server Maintenance and Management
Serverless, as mentioned before, is a misnomer and computing does, in fact, take place on servers. However, the highlight is that the developers do not have to worry about the servers. These are looked after by the cloud provider. They take care of routine maintenance and management of the servers.
Scaling is very easy and automatic. This will depend on the growth and change in the customer base. The architecture can automatically scale when the number of users grow. A practical example of this advantage is that the application will be equipped to handle an unexpectedly large number of requests and also a single request from a sole user. In the case of traditional server architecture, the application will already have a predetermined and fixed amount of server space which can only handle a fixed number of requests. It can get overwhelmed if there is a sudden hike in usage and might lead to system shutdown.
- Cost Reduction
Another benefit of adopting a serverless system of application development is that it will help you to reduce cost significantly. Functions like server management, maintenance, scaling etc. are taken care of by the cloud provider or another vendor. Additionally, serverless employs less power to compute and also uses less human power. All you have to do is work on the code from the server-side as the infrastructure is already taken care of.
- Reusability of Components
Serverless is also more judicious and cost-effective in the long run. This is mainly because the components of the serverless architecture are reusable.
