What Is Serverless Computing And Why Is It Important

Serverless computing is swiftly gaining traction with companies like Amazon, IBM, and Microsoft emerging on the scene. But what exactly is serverless computing? And how is it impacting the computing industry?

When you’re building applications, you want them to deliver a great experience to your users. Maybe you want your application to generate in-app purchase options during a gaming session or rapidly validate street address updates or even make image thumbnails available instantly after a user uploads videos.

To make this magic happen, your application needs back-end codes that run in response to events like image uploads, in-app activity, website clicks, or sensor outputs. But managing the infrastructure to host and execute back-end code requires you to size, provision, and scale servers to manage operating system updates, apply security patches and then monitor all this infrastructure for performance and availability.

That sounds…like a lot of work! What if there was an easier way?

This is where serverless computing comes in. Serverless computing is the technology that is revolutionizing the way we build applications.

All the steps mentioned previously, apart from writing your application code (of course), are omitted with serverless applications. Instead, serverless applications allow you to focus on what is important: your application logic. All this without having to worry about any servers.
The cherry on top? Serverless applications have built-in high availability and fault tolerance.

These, however, are not the only benefits of serverless computing. Serverless applications can be scaled automatically or at the most with a few clicks to your desired capacity. No idle capacity is another benefit. You pay only for what you use and no more. For example, with traditional architecture, say you created a server with 100 GB of memory, and you’re using only 10 GB of it. You will still have to pay for the 90 GB that you’re not using. But with serverless architecture, you pay only for what you use. Neat, right?

In recent years, serverless computing has been developing at a high speed. This rapid advancement has had a large influence on the computing industry. Mainstream cloud service providers are constantly enriching their cloud service systems and providing better development tools, more efficient assembly lines for application delivery, better monitoring tools, and more sophisticated integration between services.

Serverless computing has come a long way, but this is just the beginning.
