Compose vs Docker: What are the differences?

Compose: We host databases for busy devs: production-ready, cloud-hosted, open source. Compose makes it easy to spin up multiple open source databases with just one click. Deploy MongoDB for production, take Redis out for a performance test drive, or spin up RethinkDB in development before rolling it out to production; Docker: Enterprise Container Platform for High-Velocity Innovation. The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere.

Compose can be classified as a tool in the "MongoDB Hosting" category, while Docker is grouped under "Virtual Machine Platforms & Containers".

Some of the features offered by Compose are:

• One click, production-ready, cloud hosted MongoDB, Redis, Elasticsearch, PostgreSQL and RethinkDB, with additional databases in beta.

Every deployment features: database autoscaling based on data size usage - private VLAN, IP whitelisting, SSL, full-stack monitoring, custom alerts - HA and fault tolerance with automatic failover

On the other hand, Docker provides the following key features:

• Integrated developer tools
• open, portable images
• shareable, reusable apps

"Simple to set up" is the primary reason why developers consider Compose over the competitors, whereas "Rapid integration and build up" was stated as the key factor in picking Docker.

Docker is an open source tool with 54K GitHub stars and 15.6K GitHub forks. Here's a link to Docker's open source repository on GitHub.

Spotify, Pinterest, and Twitter are some of the popular companies that use Docker, whereas Compose is used by Accenture, Artsy, and FashionUnited. Docker has a broader approval, being mentioned in 3527 company stacks & 3449 developers stacks; compared to Compose, which is listed in 82 company stacks and 19 developer stacks.
