Overview
Valex Cloud streamlines instance provisioning by always booting from volume and leveraging automatic volume‑image caching. These features improve boot times, ensure persistent storage, and reduce network load during instance creation.
Always Boot from Volume
- Persistent Boot Storage:
Every instance is booted from a dedicated volume rather than ephemeral local storage. This means your boot disk is persistent, and data remains intact even if the instance is terminated. - Improved Data Safety:
Boot volumes can be snapshotted, backed up, and managed independently from the instance lifecycle, ensuring that your operating system and configuration remain secure.
Automatic Volume‑Image Caching
- Faster Provisioning:
When a volume is created from an image, our system automatically caches the image on our storage backend. This caching mechanism significantly reduces boot times for new instances. - Network Efficiency:
By caching frequently used images, we minimize redundant data transfers, thus lowering network usage and speeding up instance launches.
How It Works
- Image Selection:
Choose the desired image for your operating system during instance creation. - Volume Creation:
The system creates a boot volume from the selected image. The image is automatically cached if it has been used recently. - Instance Launch:
The instance boots directly from the volume, benefiting from the speed and reliability of cached data.
Best Practices
- Regular Backups:
Even though volumes are persistent, schedule regular snapshots or backups for critical operating system images. - Monitor Cache Performance:
Keep an eye on boot times and system performance to ensure that the caching mechanism is operating efficiently. - Optimize Image Usage:
Use standard images across your deployments to take full advantage of caching benefits and reduce provisioning delays.
