Since the containerization boom, we have started to remove the big pieces of our applications, replacing our servers with virtual machines, our virtual machines with containers, and our containers with code “In Situ”.
But what is AWS Lambda?
AWS Lambda is an event-driven, serverless computing platform provided by AWS that enables you to run code without provisioning or managing servers in real-time. If you are running your application 24 hours a day, 7 days a week, you will be charged for the time the functions are running. The code that runs on AWS Lambda is called a Lambda function.
We can think of Lambda as an event-driven platform that executes when code that has been loaded into the system is activated and triggered.
With AWS Lambda, you can run code for virtually any type of Backend application or service. This function is compatible with Java, Go, PowerShell, Node.js, C #, Python, and Ruby code which also provides a runtime API that allows you to use any additional programming languages to create your functions.
AWS Lambda Use Cases
AWS Lambda is a service that can be ideal for many situations. The application code must be written in the previously mentioned and supported languages. Let’s see some examples of how you can use this service to simplify and automate your Cloud infrastructure:
Real-time file processing: You can use Amazon S3 to activate AWS Lambda and process your data immediately after uploading it. For example, you can use Lambda to create thumbnail images, transcode videos, index files, process logs, validate content, aggregate and filter data in real-time.
Automatic backups: You can easily write a Lambda function that will automatically create backup copies of important information. The backup can
