Introducing Striim Cloud Mission Critical

You can deploy and run applications on multiple servers for higher performance (see Adapting TQL applications for multi-server deployment).

When a server goes offline, its applications will fail over to another server (see Continuing operation after server failover).

When a server goes offline or comes back online, applications are automatically redistributed among the servers (see Automatic load rebalancing).

For higher performance, you can add additional servers to your cluster, up to a total of five (see Adding servers to Striim Cloud Mission Critical).

Monitoring features show additional information reflecting the multiple servers (as in Striim Platform).

Forwarding Agents can connect securely to Striim Cloud Mission Critical using Google's Private Service Connect. Contact Striim support for more information.

A snapshot of the metadata repository will be taken every minute rather than once an hour as in Striim Cloud Enterprise. This means that in disaster recovery you may be able to recover your applications from a more recent checkpoint than you would in Striim Cloud Enterprise, reducing the amount of time it takes for your applications to come back online.

a Striim cluster consisting of two or more Striim servers, each running in its own virtual machine

a managed, high-availability, fault-tolerant metadata repository host

a managed, high-availability, fault-tolerant Kafka cluster to support persisted streams (see Kafka-persisted streams)

A cluster has a minimum of two Striim servers. You can add additional servers, up to a maximum of five (see Adding servers to Striim Cloud Mission Critical). In the initial release, the servers will all be in the same availability zone. Adding servers is permanent, that is, the number cannot be reduced.

To match the requirements of your applications, you can resize the virtual machines (VMs) in your Striim cluster to increase or decrease the number of CPUs and amount of memory available (see Resizing Striim Cloud virtual machines). In this initial release, the VM choices are:

Upgrading to larger VMs will increase your costs, downgrading to smaller VMs will decrease your costs.
