Enabling Serverless Computing With AWS Lambda

Developing a user-friendly application is essential to deliver engaging user experiences across devices. Organizations take effective measures to ensure that their applications are fast, responsive, scalable, and adaptable to dynamically changing user requirements. They often introduce new app features or improve the existing functionalities to maximize user interaction and deliver great user experiences. For example, a messaging app must facilitate seamless conversations in real-time with minimal lag or latency. At the same time, users must be able to share media files, documents, maps location, and more. 


To achieve a seamless workflow, the application requires a backend code that runs in response to events like message transfers, image uploads, and file sharing. However, managing the app infrastructure to host and execute backend code requires multiple servers to operate. In addition, it requires the organization to routinely run OS updates, apply security patches, and monitor the app infrastructure for performance and availability. 


AWS Lambda eliminates these complexities by allowing organizations to focus on building high-quality applications without spending their time and effort on managing servers. This blog post highlights the key enterprise benefits of using AWS Lambda in cross-platform SaaS application development. 


What Is AWS Lambda?

AWS Lambda is an event-driven cloud computing platform that provides a serverless computing environment to manage web or mobile applications. It uses an event-trigger mechanism to run and execute backend code in response to events like image uploads to S3 bucket or data updates to Amazon DynamoDB tables. The trigger mechanism also works in response to all sorts of in-app activities like data transfers, profile updates, and in-app purchases. AWS Lambda employs a Function as a Service (FaaS) model and enables developers to build and manage serverless web and mobile applications. 


An apt example of AWS Lambda functions is image uploads to Amazon Simple Storage Service (S3), simply known as S3 bucket. When a user uploads an image to the S3 bucket, it triggers the Lambda function which in turn, resizes the image for various device screens.

Enterprise Benefits of AWS Lambda

AWS Lambda enables enterprises to develop cross-platform web and mobile applications without dealing with the complexities of server management and monitoring. Below are the key benefits of using AWS Lambda to strengthen SaaS and AWS development services.  


Faster Development

AWS Lambda provides a serverless app development architecture, enabling system engineers to accelerate their development efforts. Since they do not have to deal with the complexities of server management, it simplifies product engineering, resulting in development. Besides, app management becomes simpler as the engineers can focus on the key performance parameters to deliver great user experiences. 


Improved App Management

Lambda incorporates FaaS protocol which not only reduces computational expenses but also renders a simple and streamlined app management process. As a result, system engineers can effectively monitor app performance and manage core services to deliver responsive app experiences. As a matter of fact, managing a FaaS architecture is quite simple as compared to its SaaS counterparts. Since you do not have to deal with the complexities of containerization and system administration, the process becomes straightforward, thus enabling effective app management.    


Continuous Scaling 

AWS Lambda automatically scales your application in response to various trigger events while the backend code runs in parallel. It also scales the app data to match a wide range of screen sizes such as laptops, desktops, tablets, and smartphones. AWS Lambda individually processes each trigger event with effective scaling with respect to the workload size and properties.  


Reduced Operational Costs

With AWS Lambda, you only pay for the event duration when the lambda function executes the backend code. It significantly reduces operational costs and mitigates additional human efforts.


Potential Challenges

Despite numerous enterprise benefits, AWS Lambda puts up several operational challenges in the form of vendor control issues, lock-ins, security vulnerabilities, and multi-tenancy issues. While unit testing can be relatively easy for serverless apps, integration/acceptance testing is rather difficult and more complicated. Since there is no server involved, all integration and acceptance tests must be performed using remote systems.

Closing Remarks

Function as a Services is not the right solution for every app-related problem, but it can effectively address several enterprise challenges. Implementing AWS Lambda shortens the application development cycle since the system engineers can choose the right memory size for every function. Above all, it accelerates the development processes, reduces time-to-market, saves costs, and unnecessary human effort.
