Why you should learn Serverless now!

The Serverless architecture

You may have heard about it already or stumbled upon another blog post about the serverless architecture.

The serverless architecture is a modern approach to develop web applications where you don’t have to think about or manage application servers anymore. You just write your code and deploy it. Everything else which is necessary to run your application is done automatically.

The Serverless framework (GitHub) is a new web development framework which makes it easy to manage and orchestrate all the code you write when developing a serverless application. But why does this technology matter? And why should you be interesting to learn this new framework? Let’s take a look!

Monstrously scalable

You’re developing the next unicorn? Your application may have 2 users today but maybe 2.000.000 tomorrow? No problem! Serverless has you covered. Your web application scales according to the needs. You don’t have to do anything to make sure that your application runs smoothly when more and more users use your application. Everything is done behind the scenes.

No server administration

You know that managing a servers is more than typing in simple shell commands. There are security patches, updates, backups, ect. Everything has to be configured correctly to ensure that your application is protected and always up to date. Not in the Serverless world. You don’t have to be a server wizard or think about Servers at all! Just write your code and you’re good to go. The heavy stuff is done for you automatically.

Reduced costs

You have a web application but it’s not used frequently? You’re paying the servers IDLE time month after month. Serverless applications are different. You only pay for the resources you use. No users yet? No problem!

Let’s take a look at a real world cost comparison:

This is a production web application with 16000 requests a day (average response time is 200ms):

• Two EC2 instances → $2.97 / day
• Serverless architecture → $0.05 / day

Costs are reduced dramatically with a Serverless architecture!

Welcoming community

The Serverless community is a very welcoming and helpful community. Do you have problems or want to enhance the framework with a new feature? Just open up a new issue or chime in on existing conversations. You’re not alone!

Is this used in production?

Of course! More and more companies decide to use a serverless architecture. Some are migrating their old applications to Serverless, some are developing new applications from scratch.

One example is exceptionally interesting. Parall.ax has developed the new David Guetta campaign “This One’s For Your” with the help of the Serverless framework in order to have a fast time to market and an infinitely scalable web application when the fans start to use the app and share their recordings on social networks. Read more about it in this blog post.
