VictoriaMetrics Cloud offers two different deployment types: Single-node (described here ) and Cluster. Both deployment types are based on the VictoriaMetrics Open Source project , and managed by the VictoriaMetrics team.
In a nutshell, Single-node deployments are useful for affordable and performant instances, while Cluster deployments may be the ideal choice for those use cases that require higher availability and multi-tenancy at scale. More detailed information about the general capabilities of both tiers can be found in this FAQ .
For simplicity, Capacity tiers based on the VictoriaMetrics Cluster version are hidden to users, as Single-node instances cover most use cases, and the Cluster version consumes more resources, which leads to a higher price.

More in detail, the following topics should be considered when selecting a deployment type:
Reliability/SLA
Both instance types are highly reliable, with SLAs of 99.5% for Single-node deployments and 99.9%
for Cluster deployments.
High Availability
Since Single-node deployments are just one instance, they cannot be highly available. In practice,
this means that during configuration changes and software upgrades, your deployment will experience
a few minutes downtime. (This period of unavailability is not included in the SLA).
On the other hand, Cluster deployments do not experience such downtimes.
Multitenancy
While
Multitenancy
is supported in the Cluster version of VictoriaMetrics Cloud, it is not supported in Single-node
instances.
Scalability
Internally, Single-node deployments may be scaled vertically and Cluster deployments horizontally.
In practice, for VictoriaMetrics Cloud tiers, this means that vertical scaling will affect by constraining some parameters such as the maximum storage size, but horizontal scaling has no such limitations.
Data Replication
Data replication is provided for Cluster deployments only. Single-node deployments do not have
such capabilities.
Enterprise features
Enterprise features
are available in both Single-node and Cluster versions. Some of them may take a while to be exposed
in VictoriaMetrics Cloud. If you are missing any feature, or have any request don’t hesitate to

Efficiency and performance
Both Single-node and Cluster versions are highly valued for their performance in various benchmarks
and use cases in the industry. Feel free to read more about use cases and articles here
