Welcome to Altinity.Cloud. In this guide, we will be answering a few simple questions:
- What is Altinity.Cloud?
- Why should I use it?
- How does it work?
What is Altinity.Cloud?
Altinity.Cloud is a fully managed ClickHouse services provider. Altinity.Cloud is the easiest way to set up a ClickHouse cluster with different configurations of shards and replicas, with the version of ClickHouse or Altinity Stable for ClickHouse you want. From one spot you can monitor performance, run queries, upload data from S3 or other cloud stores, and other essential operations.
For more details on Altinity.Cloud abilities, see the Administrator Guide. For a crash course on how to create your own ClickHouse clusters with Altinity.Cloud, we have the Altinity.Cloud Quick Start Guide.
What Can I Do with Altinity.Cloud?
Altinity.Cloud lets you create, manage, and monitor ClickHouse clusters with a few simple clicks. Here’s a brief look at the user interface:
- A: Cluster Creation: Clusters can be created from scratch with Launch Cluster.
- B: Clusters: Each cluster associated with your Altinity.Cloud account is listed in either tile format, or as a short list. They’ll display a short summary of their health and performance. By selecting a cluster, you can view the full details.
- C: User and Environment Management:
- Change to another environment.
- Manage environments and zookeepers.
- Update account settings.
Clusters can be spun up and set with the number of replicas and shards, the specific version of ClickHouse that you want to run on them, and what kind of virtual machines to power the nodes.
When your clusters are running you can connect to them with the ClickHouse client, or your favorite applications like Grafana, Kafka, Tableau, and more. See the Altinity.Cloud connectivity guide for more details.
Cluster performance can be monitored in real time through the Cluster Monitor system.
Some of the metrics displayed here include:
- DNS and Distributed Connection Errors: Displays the rate of any connection issues.
- Select Queries: The number of select queries submitted to the cluster.
- Zookeeper Transactions: The communications between the zookeeper nodes.
- ClickHouse Data Size on Disk: The total amount of data the ClickHouse database is using.
How is Altinity.Cloud organized?
Altinity.Cloud starts at the Organization level - that’s your company. When you and members of your team log into Altinity.Cloud, they’ll start here. Depending on their access level, they can then access the different systems within the organization.
The next level down from there are the Environments. Each organization has at least one Environment, and these are used to allow users access to one or more Clusters.
Clusters consist of one or more Nodes - individual containers that run the ClickHouse databases. These nodes are grouped into shards, which are sets of nodes that all work together to improve performance and reliability. Shards can then be set as replicas, where groups of nodes are copied. If one replica goes down, the other replicas can keep running and copy their synced data when the replica is restored or when a new replica is added.
To recap in reverse order:
- Nodes are individual virtual machines or containers that run ClickHouse.
- Shards are groups of nodes work together to improve performance and share data.
- Replicas are groups of shards that mirror data and performance so when one replica goes down, they can keep going.
- Clusters are sets of replicas that work together to replicate data and improve performance.
- Environments contain different clusters into a set to control access and resources.
- Organizations have one or more environments that service your company.
Altinity.Cloud keeps your users organized in the following roles:
|orgadmin||These users can create environments and clusters, and assign users in their organization to them.|
|envadmin||These users have control over environments they are assigned to by the orgadmin. They can create clusters and control clusters within these environments.|
|envuser||These users can access the clusters they are specifically assigned to within specific environments.|
More details are available in the Account Administration guide.
