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.
