Discover the capabilities and limitations of Public Cloud Databases for Cassandra
Last updated April 7, 2022
This page provides the technical capabilities and limitations of the Public Cloud Databases' Cassandra offer.
We continuously improve our offers. You can follow and submit ideas to add to our roadmap at https://github.com/ovh/public-cloud-roadmap/projects/2.
The Public Cloud Databases offer is available in the following regions:
BHS
(Beauharnois, Canada)DE
(Frankfurt, Germany)GRA
(Gravelines, France)SBG
(Strasbourg, France)UK
(London, United Kingdom)WAW
(Warsaw, Poland)Entire database instances have to be in the same region. Multi-AZ is currently not supported.
The Public Cloud Databases offer supports the following Cassandra versions:
Cassandra recommends always installing and using the latest stable version.
Three plans are available:
Here is an overview of the various plans' capabilities:
Plan | Number of nodes by default | Read replicas | Network |
---|---|---|---|
Essential | 3 | No | Public only |
Business | 3 | Planned | Public & Private vRack |
Enterprise | 6 | Planned | Public & Private vRack |
Your choice of plan affects the number of nodes your cluster can run, the SLA, and a few other features such as private network, read replicas and backup retention.
Each cluster is provided with the Cassandra Community (GPL) license.
If any, license cost is included inside the service plans. You can't bring your own licenses.
Here are the node types you can choose from:
Essentials plans
Name | Disk (GB) | Cores | Memory (GB) |
---|---|---|---|
db1-7 | 160 | 2 | 7 |
Business plans
Name | Disk (GB) | Cores | Memory (GB) |
---|---|---|---|
db1-15 | 960 | 4 | 15 |
db1-30 | 1920 | 8 | 30 |
db1-60 | 3840 | 16 | 60 |
db1-120 | 7680 | 32 | 120 |
Enterprise plans
Name | Disk (GB) | Cores | Memory (GB) |
---|---|---|---|
db1-15 | 1920 | 4 | 15 |
db1-30 | 3840 | 8 | 30 |
db1-60 | 7680 | 16 | 60 |
db1-120 | 15360 | 32 | 120 |
Right now, all nodes of a given cluster should be of the same type and live in the same region.
Public networking can be used for all the offers.
Private networking (vRack) is planned for Business and Enterprise.
When using private networking, some network ports get created in the private network of your choice. Thus, further operations on that network might suffer from some restrictions - e.g. you won't be able to delete the network if you didn't stop the Public Cloud Databases services first.
Ingress and Egress traffic are included in the service plans and unmetered.
Logs and metrics are available via the OVHcloud Public Cloud Control Panel. As of today, you can't export logs and metrics, nor plug them into a remote tool.
Please note that if the database instance is deleted, logs and metrics are also automatically deleted.
We would love to help answer questions and appreciate any feedback you may have.
