FAQ on Planetary Quantum

What is Docker?

Mon, 01 Jan 0001 00:00:00 +0000

Docker is the world’s most widely used container engine.

What are the benefits of containerization?

Mon, 01 Jan 0001 00:00:00 +0000

Containerization is beneficial from several angles:

Containers always behave in the same way, regardless of the environment — this means that staging and local development environments are often trivial to set up. And since containers are built using deterministic Docker files, configuration changes are now integrated in the normal code workflow — from code reviews and tests to CI/CD solutions.

The division of an app into different containers makes dependencies visible and components can be individually exchanged and scaled independently.

What are the benefits of Docker Swarm?

Mon, 01 Jan 0001 00:00:00 +0000

Docker Swarm makes it easy to distribute your apps across multiple machines. It offers the advantages of Kubernetes (simple scaling through dynamic clusters, reliability, etc.) but is less complex to use and operate.

Docker Swarm stacks are configured using simple YAML files, similar to docker-compose. Porting a docker-compose project to Docker Swarm is trivial in practice; the concepts are similar and you get the advantages of a cluster system without much additional effort or changes.

What do I need to get started with Planetary Quantum hosting?

Mon, 01 Jan 0001 00:00:00 +0000

Planetary Quantum has no special requirements, basically any type of application can be run. It becomes particularly easy if your app already has a Docker-compose or Docker Swarm setup — these can be deployed directly on Planetary Quantum.

But even if you’re just starting out with Docker, container setups are quick and easy to use. Ready-made Docker images exist for almost all apps, and the widespread use of Docker means that working setups for many common stacks (Ruby On Rails, LAMP, …) are often only a Google search away.

How do I know which add-ons I need?

Mon, 01 Jan 0001 00:00:00 +0000

We are happy to support you in choosing the right add-ons. You can add these at any time.

How do I know which hosting package is right for me?

Mon, 01 Jan 0001 00:00:00 +0000

Since Docker’s overhead is generally negligibly small, you can easily orient yourself on the resources you have previously required.

However, it is advisable to choose a slightly larger Quantum Cluster so that you can also benefit from the flexibility that Docker offers — staging environments etc. are often easy to set up — if the resources are sufficient.

Planetary Quantum Clusters (no matter what size) have no artificial limitations except for the booked CPU/RAM/HDD resources.

How do I upgrade my hosting package?

Mon, 01 Jan 0001 00:00:00 +0000

Adding nodes to a cluster is possible without downtime. Upgrades of individual nodes are associated with minimal downtime. In both cases, you can simply contact us to upgrade.

Are the add-ons specific to a respective hosting package?

Mon, 01 Jan 0001 00:00:00 +0000

All add-ons are compatible with any of our hosting packages.
