How to Get the Most from AWS Lambda Serverless Architectures

AWS-Lambda-Serverless-Architectures

A serverless architecture is whereby a system runs without the need for traditional servers. The applications rely on third-party services and custom code to function. AWS Lambda is one product that has propelled the use of serverless applications.

A few good examples of how serverless architecture works includes real-time data processing, the backends of IoT and mobile. The idea of going serverless is not usually welcomed readily by many companies to avoid application errors. However, with the correct use of AWS Lambda, it is possible to create a stack of applications that function optimally without the need for server management

What You Get with Serverless Architecture 

Before you can switch to a serverless system, it helps to know the offerings it comes with:

  • The biggest benefit is the lack of server management. You don't have to keep servers running to manage your applications, which frees up a lot of time.
  • Ensuring that server software is updated, running efficiently and handling administration duties can take up significant resources. The saved time can be channelled into other focus areas of a business to improve it.
  • Serverless architectures have fault tolerance and availability that is built into the system. It means that you don't need to spend time creating these capabilities for the applications.
  • You only have to pay for what you are using. Amazon Web Services doesn't charge if the client's code is inactive. For this reason, you can have a precise budget without provisioning too little or too much for specific purposes. 

Getting It Right with AWS Lambda

Once you decide to implement architecture on AWS Lambda, learn some of the best practices:

  • With this type of system, you don't have to concern yourself with the OS, which means you get to deal with a different set of problems than you are used to like data encryption. When developing serverless applications, you have to focus on your code development. 
  • Security is a big priority when creating any system, serverless or otherwise. In this instance, security refers to the measures you take to guarantee safe and secure code. Take the time to come up with a stack of applications that are well controlled in terms of access. AWS offers advice on how to provide secure code that works with your web services. 
  • Reliability is another aspect that a developer should keep in mind when creating serverless architectures. Always assume that your code could fail and anticipate any possible problems that could arise. If your applications are to provide the default fault tolerance that they are meant to, they have to be dependable. Have a recovery system for your code. If your Lambda function fails, how will the application respond? Users should be assured of a smooth experience even when events fail. It may be something as simple as sending an error message. 
  • To get the most out of serverless applications, ensure that your functions can achieve maximum performance. When assigning computer resources, ensure that you pick enough storage for the intended functions. 


Amazon Web Services makes it less complicated to move to serverless architectures by providing a reliable and efficient logic layer.
