In this article, I explain in detail how to start using AWS Lambda for serverless applications. What is serverless aws lambda and how to use it. An overview of Lambda service provided by AWS. AWS (Amazon Web Services) is one of the biggest Clouds available on the internet. When choosing to build a serverless application.
In this article, I explain in detail how to start using AWS Lambda for serverless applications. How to set up your first function, and how to connect it to other services. I rarely write step-by-step tutorials, most of my articles contain code with explanation, but I wanted to give it a try.
AWS (Amazon Web Services) is one of the biggest Clouds available on the internet. The Cloud is a collection of services that a Big Tech is allowing you to rent based on your use. Instead of spending millions on your own infrastructure, you can have access to computing power, networking services, analytics tools… for the cost of a few cents (if you are small), up to the cost of millions (if you are big and you are scaling).
When choosing to build a serverless application, instead of renting a server that has to run 24h to provide the backend of your application when the client connects, you allow the server to be activated only in case of need. When a client performs an action on your website, this triggers the function which can perform an algorithm of your choice (sending emails, gather or send data, authorizations): anything that you could not do directly in the frontend.
Choosing serverless rather than server-based computing will likely save you money, especially if you are small and not so many people are using your website, but you NEED TO KNOW HOW TO DO IT. In the beginning, if you are used to coding everything in a flask or Django framework, you may find the notion of serverless quite confusing.
In this tutorial, these are the instruction you need to follow if you are new to AWS:
Code your function
Serverless Proxy with AWS API Gateway and AWS Lambda. We can communicate between Public and Private instance via a Serverless Proxy thanks to AWS Api Gateway and AWS Lambda. Github Webhook calls a Public API Gateway, API Gateway triggers a Lambda attached to VPC.
Serverless Express enables you to easily host Express.js APIs on AWS Lambda and AWS HTTP API. Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more!
In this article, we explain general API implementation concepts using AWS Lambda and other AWS services. APIs are a crucial part of any web application and there are different techniques for development and design. Serverless is one approach gaining popularity, because of its cost-efficiency, scalability and relative simplicity. As a leading serverless provider, Amazon Web Services (AWS) has made a huge contribution to the world of serverless development, and in this article, we will explain general API implementation concepts using AWS Lambda and other AWS services.
Serverless APIs with Python, AWS Lambda & API Gateway
APIs, short for Application Programming Interfaces, are connection points that allow different (parts of) computer programs to exchange data. Using APIs for the delivery of a software service makes your code better organized and easily reusable. In this article, I am going through the basic steps of creating an API using AWS Lambda and API Gateway.
