Docker
App containerization.
What it is
Docker has fundamentally changed how software is built, shipped, and run. It allows developers to package applications and all their dependencies into standardized units called 'containers.' This ensures that your app runs exactly the same way on your laptop, a staging server, or a production cloud environment. It eliminates the 'it works on my machine' problem forever. By isolating applications from the underlying infrastructure, Docker makes it easy to scale services and manage complex microservices architectures.
Docker pricing
Docker publishes 3 plans. Paid tiers start at $9/user/mo billed annually.
| Plan | Price | What the vendor’s page says |
|---|---|---|
| Pro | $9/user/mo billed annually | Pro $9/user/month annual, $11 monthly |
| Team | $15/user/mo billed annually | Team $15/user/month annual, $16 monthly |
| Business | $24/user/mo | Business $24/user/month |

Strengths and trade-offs
What works well
- Environment Consistency: Guarantees your app behaves the same everywhere.
- 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.
Where it falls short
- 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.
Who it is for
DevOps Engineers and Software Developers.
Pick it or skip it
Pick Docker if
- Individual developers — the Personal plan is free and covers unlimited public repositories
- Open-source work, where public repos carry no storage or count limit
- Small teams comparing seats: Pro is $9/user/mo billed annually
Skip it if
- Your CI pulls images constantly — the free plan is capped at 100 Docker Hub pulls per hour when logged in
- You need more than one private repository; the free plan includes exactly 1
- You are more than one person: Personal is a single-user plan
Our verdict
Free for individuals; paid tiers add org features and support. The standard way to containerize and ship software — skip it for simple static hosting.
