aws-appsync-community VS aws-cdk

For context; the web application is built with React and TypeScript which makes calls to an AppSync API that makes use of the Lambda and DynamoDB datasources. We use Step Functions to orchestrate the flow of events for complex processing like purchasing and renewing policies, and we use S3 and SQS to process document workloads.

AWS AppSync is a serverless GraphQL offering by AWS, previously I authored a blog about AWS AppSync 101 which gets you up to speed with the capabilities of AppSync and how you can leverage them in your serverless applications.

Amplify Studio's Data allows you to define Amazon DynamoDB keeping in mind the properties with the right type and also powered with AWS AppSync where which generates a GraphQL schema under the hood.

AWS AppSync I'm keeping this section a bit shorter for you all, since AppSync is not something I have actually used personally, but have heard great things about. AppSync is another API option AWS has made available specifically for applications that want to take advantage of GraphQL or a Publish/Subscribe model. The GraphQL model may be of interest to front end developers that need to query multiple sources of data from one API endpoint, like databases or microservices. The Pub/Sub model I am more familiar with in the IoT hardware-communicates-with-software aspect, however this is also powerful for frontend developers looking to take advantage of real-time updates with serverless WebSocket connections. With AppSync, you also have caching, offline data synchronization, and real-time updates. You can learn more and check out the developer docs on the AWS Website.

5. Amazon Appsync

Amplify is a set of tools that allows full-stack web and mobile developers to create and build apps. It makes using AWS services, like our Cognito identity and access management service, or our managed GraphQL service AppSync, much simpler and straight forward to use.

This was the top-voted, long-awaited request for AppSync.

Appsync is the AWS service focus on creating flexible APIs, and Amplify is the framework that combines multiple AWS tools to help you build any type of Application.

Check out AppSync (https://aws.amazon.com/appsync/) or Apollo, you can deploy Apollo app to AWS as serverless application.

environment: Specifies the environment variable that will be available to our Lambda function. In this case I wrote an environment for RDS Database. Anyway, later I will write about AWS CDK using Python for creating database clusters, etc.

Today, I will show you how to build Amazon Location Service, which allows you to build location-based applications within your AWS environment using AWS Cloud Development Kit (AWS CDK) and AWS CloudFormation. I will also show examples of the recently popular CDK Migrate and AWS CloudFormation IaC generator.

AWS Cloud Development Kit (CDK): is an open-source software development framework to define your cloud application resources using familiar programming languages.

I am not one to build programming languages on a whim. In fact, I've spent the last five years building the AWS CDK, which is a multi-language library that addresses some of the challenges I am talking about by allowing developers to define cloud infrastructure using their favorite programming language.

I recently started exploring SST as an alternative to my favorite full-stack set consisting of Projen, AWS CDK, and React. I have been thoroughly impressed with the experience so far. In this article, I will demonstrate how to create a Next.js App Router S3 Picture Uploader using SST.

AWS CDK

For KMS 🔑, Each key is ~$1/mo, and with CDK, keys are generated on a massive scale, if not centralized.

Here is a github repository containing the code and instructions on how to automate this whole setup using AWS CDK.

Now that you have a working smart contract event listener, we'll deploy the resources to AWS using AWS CDK, which is an Infrastructure as Code (IaC) tool. AWS CDK allows you to configure, deploy, and manage AWS cloud resources using popular programming languages such as TypeScript.
