Transient virtual servers for Classic
Classic IBM Cloud® transient virtual servers are a good option if you have flexible workloads and want cost savings. You can save money by running your workload on a transient virtual server. Classic transient virtual servers are provisioned when unused capacity is available. Therefore, when data center resources are needed for full, on-demand accounts, you can also lose those resources. Transient virtual servers are deprovisioned on a first-on, first-off basis when those resources need to be reclaimed.
Classic transient virtual servers offer the following flexibility:
-
Global availability
Transient virtual servers are available in data centers across the globe.
-
Cost savings
Transient virtual servers are ideal for nonproduction workloads. For example, you might use a transient virtual server to test and develop applications, or test scalability in Classic environments that don't require constant uptime.
Transient virtual servers are public virtual servers that use SAN-backed storage. The following families of public virtual servers are available for this offering.
| Families | Description |
|---|---|
| Balanced | Best for common cloud workloads that require a balance of performance and scalability. Uses network-attached storage. |
| Compute | Best for moderate to high web traffic workloads. |
| Memory | Best for memory caching and real-time analytics workloads. |
Notifications
When configured, you can receive automated reclaim notifications that help you prepare and reduce lost data. For more information, see Configuring automated reclaim notifications.
Limitations
Consider the following limitations before you provision a transient virtual server.
- The number of supported, concurrent virtual servers are part of your account-wide device quota. For more information about concurrent virtual server limits, see FAQ: Virtual servers.
- You can't change transient virtual server configurations.
- Resources can be reclaimed at any time, without notification.
- Transient virtual servers cannot use local storage.
- Transient virtual servers cannot use GPU-based or variable compute profiles.
Next steps
After you review and select your virtual server profile, it's time to provision your transient virtual server. To get started, see Provisioning transient virtual servers.
