5 Reasons To Use AWS Lambda

In a previous article, we discussed the important things to consider before running your applications on AWS Lambda.

This article will walk you through some of the amazing benefits of using AWS Lambda to deploy your applications. This knowledge might come in useful in your interviews, so pay attention!

Running applications requires provisioning and managing fleets of servers before installing your code. With AWS Lambda you don’t have to worry about managing servers which is a huge flex and it will afford you more time to focus on maintaining and managing the application itself, while Lambda takes care of the underlying infrastructure which includes updating, patching, etc.

This is a good reason to deploy your application on Lambda, as you no longer have to manage servers.

AWS Lambda is cost-effective, as you only pay for the time your code runs. Idle moments are not charged, and it's a great way to save your organization from spending so much money. If you can help a company save on their cloud bills, then this will put you ahead of the other candidates.

With Lambda pricing, the first million requests processed through Lambdas are free every month as part of the free tier, and the next million requests only cost about $0.25. For comparison, processing 2 million requests every month with EC2 will cost hundreds of dollars.

Growth is essential and should be taken into consideration when architecting a solution in the Cloud. With AWS Lambda, you can scale up and scale down your infrastructure based on the number of requests your application receives without having to do so manually. AWS Lambda is highly scalable.

Lambdas can scale to thousands and millions of requests in seconds and milliseconds, whereas scaling this much in EC2 would be a lot slower and could potentially cause errors due to not scaling quickly enough.

You can easily deploy your code on Lambda through the AWS Management Console, AWS Command Line Interface (CLI), or AWS Cloud Formation. You package your code into a zip file, log into the management console, navigate to the Lambda console, create a function, and upload the zip file.

Easy deployment is an advantage of using AWS Lambda, as you don’t need to go through a strenuous process before uploading your code.

As a Cloud Engineer, you’ll likely use other services when building a solution on AWS. With AWS Lambda, your integration process will be easy because AWS Lambda offers a seamless integration process with other AWS services such as Amazon S3, Amazon DynamoDB, and Amazon API Gateway.

The addition of other services will help build a more powerful and reliable application.

Part of AWS best practices includes building a highly available solution, Aws Lambda does that for you as it automatically replicates your code across multiple availability zones, which helps ensure the high availability and reliability of your applications.
