Containerized Services:
A containerized service is an application or microservice that runs inside a lightweight, standalone, and executable container. Containers package everything needed to run an application, including the code, dependencies, and runtime environment, ensuring it runs consistently across different environments.
Docker Containers:
Docker is a popular platform for containerization, allowing developers to create, deploy, and manage containers easily. A Docker container is an isolated unit that runs a specific application with all its dependencies, ensuring consistency across development, testing, and production environments.
Benefits of Containers
- Portability: Runs anywhere (local, cloud, server, etc.).
- Scalability: Can be replicated and auto-scaled easily.
- Efficiency: Uses fewer resources compared to VMs.
- Consistency: Works the same in dev, test, and production.
