GETTING STARTED WITH AWS Lambda

With cloud computing replacing layer after layer of the server room’s hardware with virtual servers, what if the servers themselves be virtualized?

Gartner reports that by 2022, more than 25% of companies will have switched to serverless computing as it truly enables platform as a service serverless computing. So are you looking to use AWS Lambda for the first time? Or are you evaluating its use for a production environment?

For those who still aren’t aware of what serverless computing with AWS Lambda is, let’s start with a simple explanation. AWS Lambda lets you run an application without managing servers. A responsive cloud serviceAWS Lambda is Amazon’s serverless compute service that allows you to run code without having to manage servers on containers. Going serverless means that your developers just need to focus on building world-class web applications and worry less about infrastructure management.

If we talk about a simple use case when an image is uploaded into Amazon Simple Storage Service (S3), a Lambda function could automatically resize the image for mobile, tablet, desktop devices. 

Let’s look at some of the features AWS Lambda offers to us:

  • Easier Operations: Developers can write the code directly without managing the continuous delivery and integration tools. System engineers can focus on managing the core services accurately with a clear separation between infrastructure services and applications running on top of the platform.
  • Faster Development: It has helped the system engineers to spend more time on major development issues rather than operational issues. Engineers can now concentrate more on the actual business logic of the application.
  • Pay per use: AWS Lambda is cost-effective as it allows you to pay only for the time you use and compute your functions.
  • Automatic Scaling: With AWS Lambda, there is no pre-scaled pool, no scale levels to worry about, and no settings to tune—and at the same time your functions are available whenever the load increases or decreases.
  • Reduction in Operational Costs: AWS Lambda allows operational cost reductions as it charges 95% less as compared to running a server for an entire month.

AWS Lambda is the perfect example of serverless architecture – computing execution layer in the cloud where providers manage the resources.  It employs Function as a Service (“FaaS”) model of cloud computing. This allows you to build and run applications and services without managing infrastructure. Google Cloud Functions, Iron.io, Serverless, IBM’s OpenWhisk project, and Azure functions are some popular examples of serverless platforms.
