# Cloud Units
![](img/cloudunits_abstract.jpg)
## What are Cloud Units?
Cloud units are the basis for price calculation for anyone intending to use/deploy on the Threefold Grid.
Cloud units are a unified way to account for virtual hardware resources on the ThreeFold Grid. They represent compute, storage and network equivalents to energy (kW - kilowatt). The are three categories of cloud units:
- Compute Unit (CU): The amount of data processing power in terms of virtual CPU (vCPU) cores (logical [CPUs](https://en.wikipedia.org/wiki/Central_processing_unit)) and Random Access Momory ([RAM](https://en.wikipedia.org/wiki/Random-access_memory)).
- Storage Unit (SU): The amount of storage capacity in terms of Hard Disk Drives (HDDs) and Solid State Drives (SSDs) in Gigabytes (GB).
- Network Unit (NU): The amount of data that travels in and out of storage units or compute units expressed in GB.
> Note: [Resource units](./resource_units_calc_cloudunits.md) are used to calculate SU & CU. Resource Units are used to measure compute and storage capacity produced by hardware.
When a solution is deployed on the ThreeFold Grid, the system automatically gathers the required amount of CU, SU, or NU. It is important to note that users are not billed upon reservation but only when utilizing the actualy CU, SU and NU. TF Certified Farmers can define the price of CU, SU, and NU they make available on the ThreeFold Grid.
## How is the price of Cloud Units (v4) calculated?
The following tables display how cloud units (v4) are calculated on the ThreeFold Grid. The 4th version of cloud units are used since Grid 2.2+ in mid 2020.
### Compute Capacity
| CU (Compute Unit) | | | | |
| ------------------------------------- | --- | --- | ---- | --------------- |
| GB Memory | 4 | 8 | 2 | |
| nr vCPU | 2 | 1 | 4 | |
| Passmark Minimum (expected is double) | 500 | 250 | 1000 | CPU performance |
The passmark (CPU benchmark or alternative) is not measured on the grid yet. It is used in simulators to check the mechanisms and ensure enough performance per CU is delivered.
Example of Compute unit:
- 4 GB memory & 2 virtual CPU (and 50GB of SSD disk space)
- Recommended price on TF Grid = 10 USD
- Alternative cloud price = between 40 USD and 180 USD
See how we compare with the market compute prices [here](./pricing/pricing.md).
### Storage Capacity
| SU (Storage Unit) | HDD | SSD |
| ------------------- | ---- | --- |
| GB Storage Capacity | 1200 | 200 |
HDD is only usable for Zero Database driven storage (e.g. ThreeFold Quantum Safe Storage). 1.2 TB of HDD is provided following the advised storage policy of 16+4 with 20% overhead. So the net usable storage would be 1TB. In other words, the SU corresponds in that case to 1TB of net usable storage and an extra 200GB for redundancy.
Example of Storage unit:
- 1TB of usable storage as provided by the Zero-DBs (the backend storage systems)
- Recommended price on TF Grid for 1 SU = 10 USD
- Alternative cloud price = between 20 USD and 200 USD
See how we compare with market storage prices [here](./pricing/pricing.md).
### Network
| NU (Network Unit = per GB) = NRU per month | GB (NRU) |
| ------------------------------------------ | -------- |
| GB transferred OUT or IN | 1 |
> We use SU-month and CU-month to show SU monthly costs. This can be compared to kilowatts (kW) to see electricity usage per month. Learn more about how this is calculated with [Resource units](./resource_units_calc_cloudunits.md), a way to measure the compute and storage capacity produced by hardware.

# Cloud Units Advanced
## How is the price of Cloud Units (v4) calculated?
The following tables display how cloud units (v4) are calculated on the ThreeFold Grid. The 4th version of cloud units are used since Grid 2.2+ in mid 2020.

### Dedicated Servers
Starting April 2022, the TFGrid 3.0/a5 has support for dedicated servers. You can reserve a full server and the server is only usable for you, a minimum of 70% discount is given for this usecase.
- Dedicated Node, 192 GB mem, 24 cores, 1000 GB SSD = 75 USD per month (max discount, 3Y staking)
- Dedicated Node, 32 GB mem, 8 cores, 1000 GB SSD = 31 USD per month (max discount, 3Y staking)
Above example was with generous 5TB of bandwidth used per node per month, which is huge.
These nodes are ideal to deploy blockchain nodes, or other high demanding workloads. Dedicated nodes leads to amazing pricing.
To use a dedicated node, you will have to reserve a 3node for yourself in your admin portal of TFGrid, only you can then deploy on this node and there is no additional cost.

## Pricing Expressed Per Month
| Cloud Units | description | USD NO DISCOUNT | USD 60% DISCOUNT |
| ----------------- | ------------------------------------------------ | ------------------- | ---------------------------- |
| Compute Unit (CU) | typically 2 vcpu, 4 GB mem, 50 GB storage | 22.00/month | 8.80/month |

| IPv4 Address | Public Ip Address as used by a TFGrid user | 5.00/month | 3.00/month |
## Operation Fees
Operations on TFChain have a base fee of 0.001 TFT. Creating and destroying deployments usually includes several operations.
## Certified Capacity
Renting capacity on certified nodes is charged 25% extra (x 1.25).
## Dedicated Nodes
Since April 2022, TFGrid has introduced dedicated server support. With dedicated servers, you can reserve a full server exclusively for your use. This comes with 50% discount, making it a cost-effective option.
Here are two examples of dedicated nodes and their prices, with maximum staking discount level (Gold => -60%) for 18 months staking:
- Dedicated Node 1: 192 GB memory, 24 cores, 1000 GB SSD = $75 per month
- Dedicated Node 2: 32 GB memory, 8 cores, 1000 GB SSD = $31 per month
> Please check our [Cloud Pricing for utilization sheet](https://docs.google.com/spreadsheets/d/1E6MpGs15h1_flyT5AtyKp1TixH1ILuGo5tzHdmjeYdQ/edit#gid=2014089775) for more details.
These dedicated nodes come with a generous 5TB bandwidth usage per node per month. They are well-suited for deploying blockchain nodes or other resource-intensive workloads. Using a dedicated node requires reserving a 3node in your TFGrid admin portal. Once reserved, you have exclusive deployment rights for that node, and there are no additional costs.
When renting a dedicated node, you receive a 50% discount for the entire node. However, it's important to note that you will still be required to pay for the entire node, even with the discount applied. This means that while you enjoy the discount, the cost of the dedicated node is not prorated based on the resources you utilize.
## Staking Discount
| Type | Pricing Level | Nr months of TFT linked to account |
| ---------- | ------------- | ---------------------------------- |
| No staking | - 0% | 0 |
| Default | - 20% | 1.5 months |
| Bronze | - 30% | 3 months |
| Silver | - 40% | 6 months |
| Gold | - 60% | 18 months |
TFChain charges users for proof of utilization on an hourly basis. The discount applied is determined by the amount of TFT (ThreeFold Token) available in the user's TFChain account. It's important to note that the discount is calculated based on the TFT balance in the TFChain account, not on other supported blockchains like Stellar.
This discount mechanism operates automatically, and users don't need to take any specific actions to avail themselves of this benefit. However, it's worth mentioning that the maximum discount for network-related services is 40%.
### Example for 40% discount (Silver)
Let's break down the example for a 40% discount on Internet Capacity consumption:
- Suppose your consumption on the ThreeFold Grid is worth 10 TFT per hour.
- To be eligible for a 40% discount, you need to have a minimum of 43,200 TFT in your account, calculated as 10 TFT * 24 hours * 30 days * 6 months.
- Similarly, to be eligible for a 60% discount, you would need a minimum of 129,600 TFT in your account, calculated as 10 TFT * 24 hours * 30 days * 18 months.
- If you have 60,000 TFT in your TFChain account, you would receive a 40% discount.
- However, since you don't have enough tokens to qualify for the 60% discount, it won't be applicable.
- With the 40% discount, your effective payment for the consumption would be 6 TFT per hour, as long as the amount of TFT in your account falls within the range of 43,200 to 129,600 (as calculated above).
Keep in mind that these calculations are based on the example provided and the specific discount levels mentioned.

| silver | - 40% | 12 months |

TFChain charges the user for proof_of_utilization every hour. TFChain will calculate the discount based on amount of TFT available in the account of the user on TFChain (not on Stellar or any of the other blockchains we also support). This is an automatic form of staking, the user does not have to do anything to have this benefit. For network related services its max 40% discount.
### Example for 40% discount
- I've used 10 TFT worth of Internet Capacity on tf_grid for the last hour.
- 10TFT * 24 * 30 * 12 = I would need 86,400 TFT for one year
- 10TFT * 24 * 30 * 36 = I would need 259,200 TFT for 3 year
- I have 120,000 TFT in my account on TF_Chain, this means that I will get 40% discount.
- I don't have enough tokens to get to 60% discount.

## Resource Units Overview
The threefold Zero-OS and TFChain software translates resource units (CRU, MRU, HRU, SRU) into cloud units (CU, SU) for farming reward purposes.
Resource units are used to measure and convert capacity on the hardware level into cloud units: CU & SU.
| Unit Type | Description | Code |
| ------------ | ------------------------------------ | ---- |
| Core Unit | 1 Logical Core (Hyperthreaded Core) | CRU |
| Mem Unit | 1 GB mem | MRU |
| HD Unit | 1 GB | HRU |
| SSD Unit | 1 GB | SRU |
| Network Unit | 1 GB of bandwidth transmitted in/out | NRU |
These are raw capacities as measured by the ThreeFold software running on Zero-OS.
To learn how they convert into cloudunits see [here](./resourceunits_advanced.md)
### Compute
For farming, 1 CU equals:
- 2 virtual CPUs with a maximum over subscription of 4 CPUs and minimum required memory of 4GB.
- An over subscription of 4 CPUs remains still gentle as we understand many other providers use more.
- There needs to be at least 50GB SSD per CU, if not there is penalty for nr of CU, reasoning is that otherwise people cannot deploy their VM's or Containers if there would not be minimal SSD.
```python
cu = min((mru - 1) / 4, cru * 4 / 2, sru / 50)
```
- 1 GB of memory is subtracted for the operating system to function.
- please note minimal passmark per CU (with 4GB mem), needs to be 1000 passmark at farming side, this is not being checked today but might be done in future. If your chosen CPU has less than 1000 passmark per CU (of 4 GB mem), it could be your final CU's will be lower once that feature is introduced.
<!-- > NOTE 17 Jan: some possible abuse has been found, we will do research how to adjust calculations to avoid this. -->
### Storage
For farming, 1 SU equals to:
- 1.2 TB of HD capacity (which can deliver 1 TB of net usable storage)
- 200 GB of SSD capacity with a buffer of 20%
```python
su = hru / 1200 + sru * 0.8 / 200
```
#### Storage cost price verification Dec 2021
- price for 16 TB HDD = 300 USD
- 16000 / 1200 = 13.3 SU
- 1 SU costs = 300 / 13.3 = 22.5 for HDD
- price for 2 TB SSD = 200 USD
- 2000 * 0.8 / 200 = 8 SU
- 1 SU costs 200 / 8 = 25 for SSD
<!-- !!!include:staking_farmed_tft -->
## Change Log
- original non final specs from Summer 2021, was mentioned its not final.
- Dec 2021 update for launch v3.x
- there need to be at least 50 GB SSD capacity per CU
- was in the specs of farming reward but formula above did not take it into consideration, in others nonconsistenty between specs & formula.
- sru division to 200, was 300, to be more in line with HDD vs SSD pricing, this check needs to be done +- every 6 months, results in slightly more SU, which is good for farmers.
- Jan 2022 update for launch v3.x
- reverted change done in Dec, sru does not have to be deducted from cpu, results in increase of farming rewards, in other words good for farmers. Also good formula more easy.
- Introduced warning about minimum CPU requirements in relation to passmark.
## Remarks
- There seems to be issue in simulator play.grid.tf, will check asap (17-jan)
- We are checking all numbers & the DAO is coming life in Jan/Feb 2022, once we have the DAO every change of the specs needs to be approved by DAO voting members. For now we use the forum to notify and ask feedback and make sure farming reward goes up for the changes if possible. There ia already a minimal DAO life, the blockchain TFChain validators (L1) need to find consensus to upgrade code.

# Resource Units Calculation
## Calculation from resource units to CU/SU for farming purposes
The threefold Zero-OS and TFChain software translates resource units (CRU, MRU, HRU, SRU) into cloud units (CU, SU) for farming reward purposes.
### Compute
For farming, 1 CU equals:
- 2 virtual CPUs with a maximum over subscription of 4 CPUs and minimum required memory of 4GB.
- An over subscription of 4 CPUs remains still gentle as we understand many other providers use more.
- There needs to be at least 50GB SSD per CU, if not there is penalty for nr of CU, reasoning is that otherwise people cannot deploy their VM's or Containers if there would not be minimal SSD.
```python
cu = min((mru - 1) / 4, cru * 4 / 2, sru / 50)
```
- 1 GB of memory is subtracted for the operating system to function.
- please note minimal passmark per CU (with 4GB mem), needs to be 1000 passmark at farming side, this is not being checked today but might be done in future. If your chosen CPU has less than 1000 passmark per CU (of 4 GB mem), it could be your final CU's will be lower once that feature is introduced.
### Storage
For farming, 1 SU equals to:
- 1.2 TB of HD capacity (which can deliver 1 TB of net usable storage)
- 200 GB of SSD capacity with a buffer of 20%
```python
su = hru / 1200 + sru * 0.8 / 200
```
#### Storage cost price verification Dec 2021
- price for 16 TB HDD = 300 USD
- 16000 / 1200 = 13.3 SU
- 1 SU costs = 300 / 13.3 = 22.5 for HDD
- price for 2 TB SSD = 200 USD
- 2000 * 0.8 / 200 = 8 SU
- 1 SU costs 200 / 8 = 25 for SSD
<!-- ## Change Log
- original non final specs from Summer 2021, was mentioned its not final.
- Dec 2021 update for launch v3.x
- there need to be at least 50 GB SSD capacity per CU
- was in the specs of farming reward but formula above did not take it into consideration, in others nonconsistenty between specs & formula.
- sru division to 200, was 300, to be more in line with HDD vs SSD pricing, this check needs to be done +- every 6 months, results in slightly more SU, which is good for farmers.
- Jan 2022 update for launch v3.x
- reverted change done in Dec, sru does not have to be deducted from cpu, results in increase of farming rewards, in other words good for farmers. Also good formula more easy.
- Introduced warning about minimum CPU requirements in relation to passmark.
