How to achieve your serverless goals with AWS?

HomeResourcesBlogHow to achieve your serverless goals with AWS?
January 6, 2022 | AWS, Cloud
Read Time: 10:00

One of the most intriguing aspects of serverless is the speed with which it can help teams. You no longer have to dedicate resources or spend time to the undifferentiated, heavy lifting of managing the apps’ infrastructure. Instead, you could spend your time building the codes that benefit you and your business.

Serverless developers often wonder how they can get their development environment up and running. This blog post is a comprehensive guide for developers who want to set up a development environment for building serverless applications.

Modern applications are created serverless-first, which is a technique that prioritizes the use of serverless services to boost application agility throughout the stack. Amazon Web Services built serverless services for each of your stack’s three layers: computing, integration, and data storage.

Why do developers require serverless?

Before beginning to create business logic in conventional (non-serverless) systems, the developer must complete several tasks. Many of them are common and repeated processes, such as installing databases and servers or configuring backup and restore systems. Many of these frequent repetitive chores may be abstracted away using serverless technology.

Developers’ tools

Choose from a range of Amazon Web Services, open-source, and third-party web frameworks to make developing and deploying serverless applications easier. These well-known frameworks are available in a variety of languages too.

  • AWS SAM (AWS Serverless Application Model) is an open-source platform for developing serverless apps. It allows you to express functions, APIs, databases, as well as event source mappings using shorthand syntax.
  • The AWS Cloud Development Kit (AWS CDK) is an open-source software development platform that allows you to design cloud application resources in familiar programming languages.
  • The Serverless Framework is made up of an open-source command-line interface (CLI) and a hosted dashboard. They work together to manage the whole serverless application lifecycle.
  • Chalice is a Python framework for creating serverless applications. It enables you to swiftly design and deploy AWS Lambda-based apps.
  • With minimal code, straightforward and concise setup, and no formality, Arc. codes give you everything you need to develop massively scalable serverless apps.
  • js enables AWS Lambda and API Gateway deployments of Node.js apps simple.

Serverless App Deployment

One typical and practical utilization of serverless technology is to link features of multiple apps (two or more). Developers, for example, may rapidly design endpoints to handle inbound webhooks, apply business logic on the webhook payload, and send the result to another service.

A serverless application solution eliminates the need to consider numerous traditional stack activities. Developers may get started with the business logic right away and deploy it to their Amazon Web Services account with a single command.

The instructions below explain how to use this GitHub repository to deploy and test the finished application.

Prerequisites

You will need the following items to deploy an application on Serverless:

  • With an AWS account set up, the AWS Serverless Application Model (AWS SAM CLI) is installed.
  • A GitHub account and a repository with admin access are required.
  • A Slack account with app-creation capabilities.
AWS Serverless Application Model

AWS Serverless Application Model (AWS SAM) is a CloudFormation module that streamlines the process of creating serverless application resources.

It defines Lambda functions, APIs, databases, and event source mappings using abbreviated syntax. The AWS SAM syntax is translated into AWS CloudFormation syntax during deployment, allowing you to construct serverless apps more quickly.

The AWS SAM CLI is an open-source command-line tool for building, testing, debugging, and deploying serverless applications locally described by AWS SAM templates.

 

Setting up your Slack webhook for inbound communication

When a user starts a GitHub repository, this app utilizes a Slack webhook URL to make a POST request to a Slack channel.

To make a Slack webhook, follow these steps:

  • In Slack, make a new channel where you want the messages to go.
  • Select Add applications in your new channel.
  • Create a new “Incoming Webhook” application for your channel by searching for it.

A Slack webhook URL is displayed after it has been created. This URL is used by the serverless application to publish data to your Slack channel. Make a note of this URL since you’ll need it when you’re ready to publish the app.

Getting the serverless app up and running
This GitHub repository contains the serverless application code. Clone the app code to your local workstation first, then deploy it to your AWS account.

After running the right command on your local machine, changing the directory into the app’s root, and using the AWS SAM framework to build and deploy the serverless application – you can use that URL i.e., GitHub Endpoint value, as a gateway to your serverless app. Post which you need to set up your GitHub webhook.

How to achieve your serverless goals with AWS

Final Words
Amazon Web Services (AWS) dominates the cloud computing market. As more businesses move to the cloud, the need for AWS solutions architects grows. AWS’s architecture is a very lucrative way to capitalize on market demand and apply IT skills to high-paying jobs. If you’re an IT professional looking to move up the career ladder, now is your chance to change direction and take it to the next level.  AWS offers all the benefits of the cloud, including flexibility, faster time to market, and elasticity. AWS outperforms other cloud providers in the market in terms of data availability and high transmission reliability.
