Imagine a world where there are no servers, yet data management is also being performed with ease. This is the future of Cloud Computing, all thanks to AWS’s Lambda Serverless computing. With AWS Lambda, you can run your code without having to bother about servers. In simple terms, Lambda is an event driven computing platform which runs through event triggers and further runs the code to provide the output. In other words, instead of putting your code into a container or a virtual machine, you just load it into Lambda, sit back and let Lambda do the work for you. Just specify the triggers and you are set.
For example, an image which is uploaded into Amazon’s Simple Storage Service can be resized automatically through the Lambda feature. The Seattle Time uses this service extensively to resize mobile based images. Once companies create apps, they deploy them on services in order to run them extensively. However, for purposes of app deployment, it’s necessary to figure out the server space, database power needed and the storage space.
With Lambda in place, you can get rid of the possibilities of employing massive large applications and deploy an application with single action triggers. Fortunately, you only pay for the database computing power you use, which is priced at 100 millisecond increments of usage. Being the user, you have the power to choose the triggers you would like to employ, and how you would like to run them as well. As soon as the conditions are met, the triggers are deployed and the programs are executed.
When Does Lambda Come into Force?
Lambda works best in two situations. One situation involves the use of infrequent actions whereas the other situation comes into play when you want to build something efficiently and scale it quickly in terms of deployment. In both the cases, Lambda will provide a serverless approach, making it convenient for users to scale up, as and when required.
With Lambda, developers can concentrate on developing applications which involve heavy lifting in terms of application building.
At the same time, AWS has its own set of competitors, who have their own version of Lambda. For example, Google has Functions; IBM has an open sourced platform by the name of OpenWhisk, while Microsoft has invested in Azure recently. Being a trendy new platform technology, there is a lot of innovation which has gone into building the concept of serverless application deployment, making it the future of technology.
Lambda features can be used extensively with Amazon’s mobile based applications, commonly known as Amazon Mobile Hub. While this application is not being used to connect to the existing Lambda functions, it nevertheless is being used to create functions to equip them with API Gateway endpoints, which form an integral part of mobile apps.
However, there is one major drawback of serverless application deployment. With third parties in place, there are ways to free AWS Lambda workloads from lock in problems. Nevertheless, with the features’ in place, there is a lot of good technology and innovation which has gone to make this dream a true reality.
