One of the most talked-about terms in the IT world in recent times is serverless computing. Almost every enterprise is curious about the advantages that they can gain from a\u00a0<\/span>serverless web application<\/span>. Serverless computing, as the name implies, takes away the need for depending on servers. <\/span><\/p>\n

You can develop and run applications and services without any concern for servers. So, does it mean that servers are out of the equation now? Definitely not! Your applications would still run on servers. However, with the help of the <\/span>AWS serverless application<\/span>, you don\u2019t have to worry about server management. Amazon Web Services (AWS)<\/a> and its Serverless Platform offer promising opportunities for building and deploying applications on cost-effective services. <\/span><\/p>\n

As a result, you can focus more on the application code, thereby leading to substantial improvement in the functionality of your applications. With a\u00a0<\/span>serverless web app<\/span>, you don\u2019t have to worry about availability or scaling and the need for provisioning, configuration, and management of servers.\u00a0<\/span><\/p>\n

The following discussion would help you discover the step by step approach to\u00a0<\/span>build a serverless web application with AWS Lambda<\/span>. You can notice that each step in the creation of serverless web applications shows the significance of different AWS services. The discussion also presents an overview of the\u00a0<\/span>AWS web application architecture<\/span>\u00a0to understand the coordinated use of different AWS services in serverless web applications.<\/span><\/p>\n

AWS Serverless Web Applications Architecture\u00a0<\/span><\/h2>\n

As mentioned above, we can find more about the development of serverless web applications by reflecting on the\u00a0<\/span>AWS serverless application<\/span>\u00a0architecture. Basically, you can build a\u00a0<\/span>serverless web application<\/span>\u00a0by leveraging different AWS services together. All you have to do is ensure their viable configuration together followed by uploading the application code to AWS Lambda. <\/span><\/p>\n

As a matter of fact, AWS Lambda itself is a serverless compute service. Here is an image highlighting the example of serverless application architecture on AWS. You can notice the functions of different AWS services perform in the serverless architecture.\u00a0<\/span><\/p>\n

Steps for Development of Serverless Web Applications<\/span><\/h3>\n

In order to understand the above-mentioned image in detail, we need to dive into depths of this AWS serverless tutorial. The best approach for understanding each step of building an AWS serverless web application is to find out the processes in each step. Here is an outline of the different steps for developing a serverless application using AWS services.<\/span><\/p>\n

Step 1: Hosting a Static Website<\/span><\/h4>\n

The first step in building an AWS serverless web app is the configuration of Amazon S3 (Simple Storage Service). You have to configure Amazon S3 for hosting the static resources for a concerned web application. All the static web content for your application would include HTML, JavaScript, images, and CSS files. <\/span><\/p>\n

End users could access the web application through public website URL dictated by Amazon S3. As a result, you don\u2019t have to worry about running any web servers or adopt other services for ensuring availability. Here are the important steps that you should follow to host a static website. <\/span><\/p>\n
