Citus Cloud is a fully managed hosted version of Citus Enterprise edition on top of AWS. Citus Cloud comes with the benefit of Citus allowing you to easily scale out your memory and processing power, without having to worry about keeping it up and running.
Once you’ve created your account at https://console.citusdata.com you can provision your Citus cluster. When you login you’ll be at the home of the dashboard, and from here you can click New Formation to begin your formation creation.
Configuring Your Plan¶
Citus Cloud plans vary based on the size of your primary node, size of your distributed nodes, number of distributed nodes and whether you have high availability or not. From within the Citus console you can configure your plan or you can preview what it might look like within the pricing calculator.
The key items you’ll care about for each node:
- Storage - All nodes come with 1 TB of storage
- Memory - The memory on each node varies based on the size of node you select
- Cores - The cores on each node varies based on the size of node you select
Citus Cloud runs on top of Amazon Web Services. During provisioning you’re able to select your database region. We currently support:
- US East (N. Virginia) [us-east-1]
- US East (Ohio) [us-east-2]
- Asia Pacific (Tokyo) [ap-northeast-1]
- Asia Pacific (Seoul) [ap-northeast-2]
- Asia Pacific (Singapore) [ap-southeast-1]
- Asia Pacific (Sydney) [ap-southeast-2]
- Asia Pacific (Mumbai) [ap-south-1]
- EU (Frankfurt) [us-central-1]
- EU (Ireland) [us-west-1]
- South America (São Paulo) [sa-east-1]
- US West (N. California) [us-west-1]
- US West (Oregon) [us-west-2]
If there is an AWS region you do not see listed but would like for us to add support for please contact us and we’d be happy to look into it.
Other infrastructure providers¶
At this time we only support Citus Cloud on top of Amazon Web Services. We are continually exploring other infrastructure providers to make Citus Cloud available on. If you have immediate needs you could consider running Citus Community Edition or Citus Enterprise Edition. Or if you have questions about our timeline for other infrastructure providers please feel free to reach out.
Applications connect to Citus the same way they would PostgreSQL, using a connection URI. This is a string which includes network and authentication information, and has the form:
The connection string for each Cloud Formation is provided on the Overview tab in Citus Console.
By default the URL displays only the hostname of the connection, but the full URL is available by clicking the “Show Full URL” link.
Notice how the end of the connection string contains
?sslmode=require. Citus Cloud accepts only SSL connections for security, so this url paramter is required. When connecting from an application framework such as Rails, Django, or Spring you may need to explicitly specify the sslmode as well.
