A look into the what and why of software refactoring
By JSON Schema Evolution with Spring Kafka and Confluent Schema Registry
Schemas and schema registries are the governance tools that ensure vitality of data communications through configurable compatibility guardrails as patterns and rules to evolve schemas in a controlled fashion. In this article I will demonstrate how Confluent Schema Registry can be used in conjunction with JSON Schema to govern and enforce rules for schema evolution in the default backwards compatibility mode.
Spring Cloud AWS Parameter Store Integration Plus Optional JASYPT Encrypted Properties
In this article I demonstrate how to use the AWS Parameter Store to decouple and externalize configuration for a Spring Boot application.
Patterns for Command Query Responsibility Segregation (CQRS) Read Models
In this article I review the concepts of Command Query Responsibility Segregation (CQRS) emphasizing the value and flexibility that this software architecture provides through indpendentent optimization of writing and reading data access patterns.
Automate Spring Runtime Configuration with AWS Lambda, CDK, and CloudWatch Alarms
In this article I demonstrate how one can deploy a Spring Boot app the AWS Cloud with ECS and Fargate then used the Spring Boot Actuator project along with CloudWatch and AWS Lambda to modify runtime configuration in an event driven automated fashion.
Todos REST API with MuleSoft and AWS DynamoDB
In this article I present a walk through of the connonical Todos REST API which utilizes AWS DynamoDB to store todos and exposes Create, Read, Update, and Delete (CRUD) interfaces to manage todos implemented with MuleSoft's Anypoint Platform. DynamoDB is a fully managed No SQL document database provided by AWS with millisecond latency at any scale with proper data modeling. MuleSoft is the complete platform for integration and APIs.
Simplified Authentication using Spring Security with AWS Cognito and AWS CDK
This article presents an example of using AWS Cloud Development Kit (CDK) to deploy an AWS Cognito User Pool as an Identity Provider for authenticating a Spring Security enabled Spring Boot REST API.
S3 Content Distribution via CloudFront Signed Urls Provisioned with AWS CDK
In this article I demonstrate a Cloud Architecture pattern for distributing content stored in S3 but fronted by AWS CloudFront and accessed through signed URLs viable for a specified amount of time.
OAuth 2.0 and Open ID Connect Cheat Sheet
A collection of OAuth 2.0 and Open ID Connect (OIDC) terms and concepts I refer back to often.
Kafka CLI Cheat Sheet
In this article I capture a plethora of Kafka CLI commands that I've found useful. It is my goal to capture them here to serve as a cheatsheet of commands for myself and others to draw from.
