Resize VMs (upgrade / downgrade)

There are no account-level plans on Suji. Resizing happens per VM — increase or decrease the size of any individual VM whenever you want. Your other VMs and your overall organization aren’t affected. For the operational steps see Resize. This page covers the billing impact.

​

Upgrade (move to a larger size)

1. Instance detail page → Resize → pick the new size.
2. Suji reboots the VM into the larger shape (~30–90 s of downtime), confirms.
3. The new hourly rate kicks in immediately for that VM, charged from your credit balance.

There’s no “pro-rated billing cycle” because there’s no monthly cycle — every hour is its own bill.

​

Downgrade (move to a smaller size)

1. Instance detail page → Resize → pick the smaller size.
2. Disk-size constraint: the new size’s disk must be ≥ the data currently used. Disks can’t shrink below the data on them.
3. If your data exceeds the smaller size’s disk: snapshot → restore into a fresh smaller VM → destroy the old one. The dashboard surfaces this as the next step.
4. Suji reboots into the smaller shape, confirms.
5. The new lower hourly rate kicks in immediately.

A resize is a reboot, not a rebuild — volumes and state persist. If you want a rollback point, take a manual snapshot before resizing.

Examples

You have: one Large VM running 24/7. You want: to cut your bill by running only during business hours. ⚠️ Stop / Start doesn’t save you money. The cloud provider keeps the disk and IP reserved while a VM is stopped, so we still bill the full hourly rate. To genuinely pay less you have to either downsize, or destroy the VM and restore from a snapshot in the morning (~3–5 minute round-trip, plus a small snapshot-storage charge). A managed-schedule feature is on the roadmap. You have: a Small VM, traffic doubled, apps are getting OOM’d. You want: more headroom without overpaying. Resize to Medium. The new €0.0274/hour rate kicks in. Apps don’t lose state — they restart inside the larger shape. You have: a Medium VM, sized it generously for a one-time migration, migration is done. You want: to go back down. Resize to Small. As long as your data fits in Small’s 40 GB disk, it just works.

What about “downgrading the plan”?

That concept doesn’t exist on Suji — there’s no plan to downgrade. You only have VMs, each with its own size. Smaller bill = smaller / fewer / destroyed VMs.
