AWS CDK: API Gateway Service Integrations for Amazon EventBridge
The previous post described how to create an Amazon EventBridge Event Bus with Amazon CloudWatch Log forwarding using the AWS CDK. Publishing events works fine with the AWS Management Console or the AWS CLI, but you can also use Service Integrations for Amazon API Gateway; this works for HTTP and Rest API Gateways.
-
AWS CDK: Amazon EventBridge and CloudWatch Logs
Amazon EventBridge is a powerful service to build event-driven applications at scale across AWS. To get started with EventBridge, you just need to create an Event Bus; for example, using the AWS Cloud Development Kit. Next, forwarding all events to an Amazon CloudWatch Log group enables basic insights into all processed events.

AWS CDK: AppSync GraphQL API for Amazon Bedrock
Based on invoking Amazon Bedrock with AWS Lambda and Amazon API Gateway, you can adapt the AWS Cloud Development Kit example code to use AWS AppSync and GraphQL for accessing Amazon Bedrock.
-
AWS CDK: Use Amazon Bedrock with AWS Lambda & API Gateway
After using Amazon Bedrock Generative AI with the AWS CLI and AWS JavaScript SDK, this guide will explain how to create an Amazon API Gateway and use the AWS Cloud Development Kit and AWS Lambda to invoke Amazon Bedrock.
-
AWS CDK: Configure Alternative Operations & Security Contacts using StackSets
To maintain a common foundation of resources across a complex AWS Organization, CloudFormation StackSet is the perfect companion. Usually, you want to deploy a common baseline of AWS resources and additionally specificy custom deployments; like setting custom contact information for billing, operations, or security communications.
-
AWS CDK: Cross-Region S3 Replication with KMS
AWS has everything you need for secure and reliable data storage. With Amazon S3, you can easily build a low-cost and high-available solution. Together with the available features for regional replication, you can easily have automatic cross-region backups for all data in S3.
-
AWS CDK: Use Lambda with Application Load Balancer
When coming from a serverless perspective, setting up an Application Load Balancer with VPC sounds like much to do for just invoking an AWS Lambda function. Thanks to the AWS CDK, it’s not that complex.
-
AWS: Encrypted SQS with SNS Subscription using KMS
To decouple services on AWS, it’s a common pattern to use Amazon SQS and Amazon SNS. With AWS Key Management Service, you can encrypt the messages stored in the SNS topic and SQS queue. For the AWS Cloud Development Kit using TypeScript, you can easily create an architecture for secure message processing.
-
AWS: CloudFormation StackSet IAM Roles
With AWS CloudFormation StackSets you can deploy a CloudFormation template to multiple AWS Accounts or AWS Regions. You can use the AWS Management Console, the AWS CLI, or CloudFormation to use StackSets. Before using StackSets, you need to configure specific IAM roles to be used with CloudFormation StackSets.
-
AWS CDK: Amazon API Gateway integration for SQS
Most people know Amazon API Gateway from using it to build HTTP interfaces for AWS Lambda functions. But, in general, you can use API Gateway to call a variety AWS APIs using HTTPS. This post shows how to create an HTTPS interface for Amazon SQS using the AWS Cloud Development Kit.

AWS CDK: Read data from AWS Parameter Store
When you orchestrate an architecture von AWS, you’ll often end up with the need to read information like hostnames, identifiers, resource names or ARNs from somewhere for further processing. CloudFormation Stacks can have configured Outputs and Parameters, but using the AWS Parameter Store proved to be a more flexible solution. Using the AWS Cloud Development Kit in TypeScript, you can easily read data from AWS Parameter Store.

React SPA with server-side rendering on AWS Lambda
React is great for creating websites and writing applications using JavaScript. But, whenever the use of React is rejected, one of the most common reasons is the lack of a simple implementation for server-side rendering (SSR). When you search on Google for this topic, you’ll find various approaches and most of the time, people will tell you it’s complicated. But Why?
