Quick Interview Answer

Containerization packages an application and its runtime dependencies into a portable image that runs in an isolated process environment.

Detailed Explanation

Containerization packages an application and its runtime dependencies into a portable image that runs in an isolated process environment.

For .NET applications, containers can make deployment more consistent across environments and integrate well with orchestration platforms. Containers do not remove the need for configuration, security, observability, persistent storage, or capacity planning.

Code Example

Source
  -> dotnet publish
  -> Container Image
  -> Registry
  -> Runtime instances
