When Less Is More

When Serverless Chilled Netflix

We love Netflix (and chill, too!) The collection, the responsiveness, and personalized recommendations have entered the computing folklore long before many of us had even heard of the technologies that made it all possible.

But there is another technology that Netflix went big on, and saved even bigger on - Serverless.

Netflix moved a large of chunk of IT processes ranging from encoding videos parallelly before they are streamed to you, to backup systems validating data integrity, to managing alerts and notifications, and to managing security events, to serverless architecture. This saved Netflix millions of dollars of IT operational expenses.

What Is Serverless Serverless?

Serverless architecture allows running code, managing data, and integrating applications, all without managing servers.

They feature automatic scaling, high availability, and a pay-for-use billing model to increase agility and optimize costs.

This eliminates the need for infrastructure management tasks like capacity provisioning and patching.

It works by allocation hardware as and when needed by your applications. A serverless architecture can start running your applications within a few milli seconds of being triggered. The utilised hardware is relinquished as soon as the application finishes executing.

You make a huge saving on costs since you're only using the hardware for a very small fraction of time. Serverless Use Cases And When Not To Use It Use It For

• Batch processes
• Stream processing
• Business logic processing
• CI/CD pipelines

Do Not Use It When

• You have long running processes
• You are using unsupported languaues
• Your workloads are consistent
