Deployment Strategies
Blog post from Earthly
The article examines various deployment strategies for software applications, detailing their mechanisms, advantages, and disadvantages, to aid in decision-making for production server environments. It starts with the Recreate Deployment Strategy, known for its simplicity but necessitating downtime, and progresses to more complex methods like Rolling Update, Blue-Green Deployment, Canary Deployment, and Shadow Deployment. Each strategy offers different trade-offs between downtime and deployment complexity, with Rolling Update reducing downtime using multiple instances, Blue-Green requiring duplicate environments for seamless transitions, Canary testing new versions on a subset of users, and Shadow Deployment mirroring requests to test new versions without user impact. The choice of strategy depends on balancing these trade-offs, and the article suggests Earthly as a tool to enhance continuous integration pipelines.
