Serverless computing or serverless architecture is a code deployment and execution strategy where your back-end code runs on a third party server infrastructure. Serverless computing doesn’t mean that there is no server at all, it simply means that the server is owned and maintained by someone else who carries the load on your behalf.
This strategy can be quite useful for app developers, especially who are working independently or on a small scale. They can concentrate on developing the app and stop worrying about server side of things as it is taken care of by another party. Key benefits include:
Owning and maintaining your own servers aren’t cheap propositions. It involves acquisition of adequate hardware, purchasing software, setting up the server and then maintaining it. There are other overheads as well including electricity, cooling, and the support staff.
Going serverless means you do away with all that cost and hassle. You simply pay a certain amount periodically and shift all the risk and responsibility from your shoulders to someone else’s. Since serverless architecture allows your application components to run on multiple servers, it reduces the cost of idle time as servers only work when a particular component requires computing.
Good developers always take scalability into account when thinking about backend deployment. If your application fails to handle peak traffic, it’s not a good reflection on the application as well as its developer. Serverless architecture allows you to scale horizontally giving you access to as much computing power as you want.
AWS Lambda is actually capable of cloning and distributing computing power as per requirement which also helps in keeping the service charges at minimum.
Developing your own server architecture means every user accesses data from your location. In case your users are geographically remotely located, they will have to face latency issues which will cause delay in interactions and load times. Serverless architecture gets rid of the problem as the service has access points located close to the users.
Without having to bother about the server side of things, developers can’t only code apps quickly but are in a position to deploy them in no time as well. Developers can create new apps and launch them in a matter of days instead of having to wait for weeks and months.
Optimized Allocation of Resources
When server management and maintenance aren’t eating up your time, you can focus on improving and adding more to the experience of users. Developers can bring new ideas to life and have the time to add more features. It also gives developers additional time to think about their users’ feedback and plan accordingly.
These are the positive aspects of serverless architecture which makes it a tempting proposition for small to medium scale app developers. They bring down their costs, have more time to deal with user experience, don’t have to care about challenges associated with server management, and can bring their code to life in few days.
