Availability patterns are design approaches that ensure a system remains operational and accessible even in the face of failures. They include techniques such as health endpoint monitoring, queue-based load leveling, and the throttling pattern, all aimed at preventing downtime and gracefully handling spikes or…

Data Management

Data management patterns address the challenges of storing, accessing, and maintaining data in distributed cloud systems. They cover strategies for handling data consistency, partitioning large datasets, separating read and write workloads, and keeping data synchronized across services that may each maintain their…

Design and Implementation

Design and implementation patterns guide structuring cloud applications for maintainability, flexibility, and scalability. They include approaches like the Strangler Fig pattern for migrating legacy systems, the Sidecar pattern for extending service functionality, and the Anti-Corruption Layer for integrating with…

Management and Monitoring

Management and monitoring patterns focus on keeping cloud applications observable, configurable, and operable at scale. They include patterns such as externalized configuration, health endpoint monitoring, and the Ambassador pattern, helping teams gain visibility into running systems and manage them effectively…

GKE / EKS / AKS

GKE (Google Kubernetes Engine), EKS (Amazon Elastic Kubernetes Service), and AKS (Azure Kubernetes Service) are managed Kubernetes offerings from the three major cloud providers. They handle the provisioning and maintenance of the Kubernetes control plane, letting teams focus on deploying and managing their…

AWS ECS / Fargate

ECS is a container orchestration service that allows you to run Docker containers on a cluster of EC2 instances. ECS is a good choice if you want to run Docker containers on EC2 instances and have full control over the underlying infrastructure. Fargate is a serverless container orchestration service that allows…

Docker Swarm

A Docker Swarm is a group of either physical or virtual machines that are running the Docker application and that have been configured to join together in a cluster. Once a group of machines have been clustered together, you can still run the Docker commands that you're used to, but they will now be carried out by…

Kubernetes

Kubernetes is an open-source container orchestration platform originally developed by Google. It automates the deployment, scaling, and management of containerized applications across clusters of nodes, and has become the de facto standard for running containers in production environments.

OpenShift

OpenShift is a platform as a service (PaaS) built around Docker containers and the Kubernetes container orchestration system. It provides a comprehensive environment for developing, deploying, and managing containerized applications. OpenShift adds developer-centric tools and features on top of Kubernetes to…
