Study Notes
Containerization in Software Development
- A container is a lightweight and standalone executable package of software that includes everything an application needs to run, such as code, libraries, and dependencies.
- The primary advantage of containerization for developers is that it allows for consistent and reliable deployment of applications across different environments, ensuring that the application works as expected regardless of the underlying infrastructure.
Containers vs Virtual Machines (VMs)
- Containers differ from VMs in that containers share the kernel of the host operating system, whereas VMs run their own operating system, making containers more lightweight and efficient.
- Containers provide a higher degree of isolation than VMs, but less than a full-fledged VM.
Docker in Containerization
- Docker is an example of a containerization platform that provides a runtime environment for containers.
- Docker allows developers to package, ship, and run applications in containers, ensuring that the application works as expected in any environment.
Purpose of Containerization using Docker
- The purpose of containerization using Docker is to simplify the development, deployment, and management of applications by providing a consistent and reliable way to package and deliver applications.
