It is high time to make a shift and create serverless applications. If you are searching for how to build a serverless app or find a managed service provider, keep reading this article.

Building serverless web applications have many advantages for application developers. They offer higher scalability and are budget-friendly. They also free developers from the hassle of managing virtual desktops, software platforms, applications, and their data as in the servers-based models.

A serverless infrastructure allows native app development to create serverless applications. These applications are named serverless because there is no need to manage servers for their functionality. Such apps are managed by remote servers provided by managed service providers. Many companies create serverless applications using managed services where many apps run on one server or many servers combine to run one application depending on the app’s functionality. The DevOps for serverless applications are different and require a combination of various AWS services for full functionality.

How To Build A Serverless App?

Writing serverless applications require technical knowledge of writing codes and enhancing the features of the apps under development. Once you write the codes, you configure them together to create your app. Note that serverless apps require lots of configuration. And one of the most important steps of app development. Configuration is a time-consuming process. Once the configuration is complete, you must upload the application code to AWS Lambda to finally create the app.

Performance and delivering the serverless app as per the customer’s demand. Many companies are using serverless apps successfully to offer services or functionality. The most renowned examples include Microsoft Azure Functions, AWS Lambda, Google Cloud Functions and IBM OpenWhisk.

Let us discuss the five crucial steps to learning to build a serverless app.

1. Install AWS-cli and create an AWS account. Ensure it is version 6 or above to support your project.
   
   
2. Using your computer, install the serviceless framework.
   
   
3.  With your serviceless framework and AWS account, now is the time to write codes for your project. you can use Javascript, HTML or any other coding language to write codes. Developers write one or two-line codes depending on the complexity of the project. Most of the configuration task is done during this step.
   
   
4. As your coding process and configuration are complete, you have to create AWS credentials to connect with the serverless framework. If you already have credentials added to your AWS account, there is no need to repeat the step. You can connect to the AWS environment at any time to run any code to create an access key. You must securely save your access key ID and its secret access key.
   
   

With all the essential steps done, you are now ready to configure a serverless Framework with AWS credentials by running your code. Now, deploy the lambda function to AWS using special commands. Test the commands by copying the API gateway of the deployed function to the internet browser to check the final performance of the code.
