Priced by the resource. Not by plan.
You pick vCPU, RAM and SSD, and the bill is those three numbers multiplied out — there is no tier to outgrow and no feature held back behind one. This page is how the billing behaves. For the rates themselves, ask us and we will quote the shape you actually want to run.
Three resources, and nothing else per instance.
Every instance is metered on the same three things. Bandwidth is not a separate metered line, and there is no per-rule, per-check or per-seat charge hiding behind them.
vCPU
Charged per core, per month. Cores are not shared with another tenant on a burst schedule — what you pick is what the instance has.
Memory
Charged per GB, per month. No swap-backed overcommit standing in for RAM you were billed for.
SSD
Charged per GB, per month, on the volume the instance actually has attached. Snapshots are the optional backup policy, priced separately.
A multiplication, and two rules on top of it.
The shape of the bill is fixed and public even though the rates are quoted rather than published. Once you have the three rates from us, the whole invoice is checkable in a spreadsheet.
The 1.2 is the on-demand premium and 730 is the average hours in a month. The cap is the part worth reading twice: running an on-demand instance all month never costs more than the monthly figure for the same shape, so you are not penalised for forgetting to commit.
Popular points on the formula.
These are not packages and there is nothing you lose by not picking one. They are the shapes people choose most often, listed so you have somewhere to start from.
| Shape | vCPU | Memory | SSD |
|---|---|---|---|
| NANO | 1 core | 1 GB | 25 GB |
| STARTER | 1 core | 2 GB | 50 GB |
| STANDARDmost chosen | 2 cores | 4 GB | 80 GB |
| BOOSTED | 4 cores | 8 GB | 160 GB |
| PRO | 8 cores | 16 GB | 320 GB |
Any combination inside the limits below is valid — you are not restricted to these five.
The limits on one instance.
Above these, or for a fleet with its own isolation requirements, it becomes a conversation rather than a console action.
| Resource | Minimum | Maximum |
|---|---|---|
| vCPU | 1 core | 64 cores |
| Memory | 1 GB | 512 GB |
| SSD | 10 GB | 16,384 GB |
What costs more, and what does not.
The useful half of this table is the bottom of it. Monitoring, the virtual router, the outbound public address and port forwarding are included rather than sold back to you.
| Extra | Charged | Billed | What it is |
|---|---|---|---|
| Additional IPv4 | Chargeable | per IP, per month | A dedicated public address with static NAT and port forwarding, bound to one instance. |
| Load balancer | Chargeable | per month | Spread traffic across two or more instances on the same isolated network, with health-checked targets. |
| Remote-access VPN | Chargeable | per month | Reach private addresses without exposing a public port. You manage the VPN users yourself. |
| 7-day backups | Chargeable | a share of the instance, per month | A daily snapshot policy enforced at the hypervisor, keeping a week of restore points. |
| Managed service | Chargeable | per month | Patching, monitoring and hands-on operations by our team. Bought deliberately, never applied by default. |
| Setup assistance | Chargeable | one time | One engineer-led setup pass on first boot, charged once and never again. |
| Monitoring | Included | on every instance | CPU, memory, disk and network sampled every 60 seconds, with 14 days of history and threshold alerts. |
| Source-NAT public IPv4 | Included | with the account | Every account gets its own virtual router and an outbound public address. Not an add-on. |
| Port forwarding | Free | unlimited rules | Forward a public port to a private one from the console. There is no per-rule charge. |
A prepaid wallet, and one renewal date.
You top up a balance and usage draws it down as it is metered. There is no card on file being charged behind your back, and everything on the account renews on the 5th so there is one date to reconcile rather than one per resource.
Credit, one for one
A top-up buys rupee credit at face value. The tax invoice shows the taxable value and the GST inside it, under SAC 998315, against the GSTIN on your account.
Prorated per day
Your first period and any mid-cycle resize are prorated by the day, so you never pay for days you did not have. Resizing down credits the unused portion back.
No commitment discount
A yearly payment is a larger top-up at the same rates, not a cheaper one. We would rather keep you because leaving is easy than because leaving is expensive.
Fifteen days, in four published steps.
Before you ask support.
Is GST included or added on top?
Included. Every figure we quote you already contains the 18 %. The invoice splits it out so you can claim the input credit, under SAC 998315.
Why are the rates not on this page?
Because a published price is the one thing you cannot change quietly, and we would rather quote you the shape you actually want to run than have you work backwards from a list. Ask us and you get the three rates and a worked example for your own configuration.
What does a wallet top-up actually buy me?
Rupee credit, one for one. The tax invoice shows the taxable value and the GST inside that amount. Usage draws the balance down as it is metered.
How is the hourly rate calculated?
(monthly × 1.2) ÷ 730. The 1.2 is the on-demand premium and 730 is the average hours in a month. A month of continuous running is then capped at 120 % of the monthly figure for the same shape.
Why is everything anchored to the 5th?
One renewal date per account is easier to reconcile than one per resource. Your first period and any mid-cycle resize are prorated per day, so you never pay for days you did not have.
What happens if I resize mid-month?
The new shape is billed from the day you made the change, per day, and the old one stops. You can price the change first, and resizing down credits the unused portion back to the wallet.
Do I get a better rate for committing to a year?
No, and that is deliberate. A yearly payment is just a larger top-up at the same rates. We would rather keep you because leaving is easy than because leaving is expensive.
Is there a free tier or trial credit?
Nothing is published. The smallest real machine is one vCPU, one GB and 25 GB, and you can destroy it the same day. If you want to look before spending anything, the console demo runs on sample data with no account.
What is not covered by the per-resource rates?
Only the optional extras listed above — additional IPv4 addresses, a load balancer, the VPN, 7-day backups, managed service and setup assistance. Monitoring, port forwarding, the virtual router and the source-NAT public address are included, and bandwidth does not appear as a separate metered line.
Can I get an invoice against my GSTIN?
Yes. Every top-up raises a tax invoice showing taxable value and tax separately under SAC 998315, against the GSTIN and the place of supply recorded on your account.
What happens to my data if I stop paying?
Nothing, for fifteen days. The renewal charges into a negative balance, five days of grace follow with the daily rate still accruing, then the instance is powered off with its data intact, and only ten days after that is the resource reclaimed.
