What is AWS Lambda and what are its benefits?

Cloud computing has generated different services that prevent professionals and companies from having to make large investments in software and hardware. For example, you can host and run software from the cloud (SaaS), use an online platform (PaaS), or rent infrastructure to host the software (IaaS).

However, in recent years the concept of “microservice” has been advancing, a model that suggests creating and running functions separately (FaaS) instead of maintaining a monolithic system.

Thus, functions as a service (FaaS) are supported and enhanced by the serverless technology, which means power, accessibility and minimal costs.

What is Amazon Lambda and how does it relate to serverless technology?

First, talking about Lambda is talking about the service serverless computing offered by Amazon, one of the most important companies in the cloud computing market.

AWS Lambda is a service that allows you to run code or function without having to invest in or manage servers. In other words, you don't have to worry about technical issues, since Amazon (the service provider, in this case) takes care of ensuring that everything works as it should, maintaining its equipment, managing updates, etc.

In this way, Lambda executes your code only when needed and allows you to scale automatically, being able to attend from one request per day to thousands per second depending on your needs.

The technology AWS serverless It stands out because you don't need to invest in servers, it works on demand and you only pay for what you consume. Specifically, charges apply for every 100 ms of code execution and for the number of times it is activated.

Now, Lambda allows you to run any function you need from the cloud. Here you will see some of its basic applications and a couple of real use cases.

Data processing

You can use AWS Serverless technology to run code in response to a trigger, whether it's a user action or changes to your company's database.

For example, it is possible to use Lamda to:

  • Process files when uploading them to the server.
  • Process streaming data in real time for tracking.
  • Pre-process data for machine learning.

A real case is that of The Seattle Times, a newspaper in the United States that uses Amazon Lambda services to resize the images of your articles, so that they can be displayed well on different devices (phones, computers, tablets, etc.) and reproduced optimally.

Back ends

On the other hand, you can create backends through Lambda to handle web, mobile, IoT and API requests.

An example is the case of The Coca-Cola Company, which created a reward program for people who bought drinks from vending machines equipped with mobile payments.

In this case, they used AWS Lambda to run functions (back end) that counted the points earned for each purchase to update participant records automatically.
