- Resource Efficiency: Uses fewer resources than traditional virtual machines.
- Rapid Deployment: Containers start in seconds, speeding up your CI/CD pipelines.
- Massive Ecosystem: Thousands of ready-made images available on Docker Hub.
- Learning Curve: Understanding layers, volumes, and networking takes significant time.
- Security: Requires careful configuration to ensure containers are properly isolated.
- Storage Overhead: Managing many images and containers can consume large amounts of disk space.

The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Docker
The essential standard for modern software shipping and deployment.
