Learn the fundamentals of deploying applications and managing deployment environments. Understand the process of moving applications from development to production.
Deploying software is the process by which code developed on your computer gets shared with the world. The deployment pipeline typically consists of several stages that ensure quality and reliability.
Each stage serves as a quality gate, ensuring that only properly functioning code moves to the next level. This staged approach minimizes the risk of introducing bugs into production systems.
Modern deployment practices utilize multiple environments to safely test and validate changes before they reach customers.
The Beta stage is where tests run to ensure all components work together correctly. The Gamma stage uses production-like data and configuration for final validation before deployment.
Continuous Deployment (CD) is a software development practice where code changes are automatically built, tested, and deployed to production. This approach reduces manual intervention and accelerates the delivery process.
CD supports key development principles: quality through rigorous automated testing, coordination through standardized pipelines, and velocity through eliminating manual bottlenecks.
AWS Elastic Beanstalk is a Platform as a Service (PaaS) that simplifies deploying and scaling web applications. It automatically handles infrastructure details like capacity provisioning, load balancing, and application health monitoring.
Elastic Beanstalk simplifies many aspects of deployment while still providing the flexibility to customize the environment when needed.
