EBC Flex Compute is a computing environment where resources are shared and used efficiently by several users, rendering the solution cost-effective.
EBC vCPU
On the EBC platform, 1 CPU equals at least 2.4 GHz. There are 3 vCPU variants with guarantee value. The standard variant guarantees 25% of the capacity (0.6 GHz) and the guarantee value of the vCPU resources in the standard variant is 1:4.
Available vCPU guarantee values are shown in the table below.
| vCPU Variant | vCPU Guarantee Value | Use |
|---|---|---|
| EBC vCPU standard guarantee (Default) | 1:4 (25%) |
• Generic production servers • OTA servers |
| EBC vCPU high guarantee | 1:2 (50%) | • Medium-load application servers |
| EBC vCPU full guarantee | 1:1 (100%) |
• Terminal servers • High-load application servers • Latency-sensitive application servers |
EBC Purchase Units
EBC Flex Compute is purchased in purchase units (PUs).
A purchase unit is the smallest common component of compute resources, consisting of one (1) vCPU and four (4) GB vRAM. This can be purchased in any of the 3 vCPU guarantee values.
| Purchase Unit | Guarantee | Calculation Type | Description |
|---|---|---|---|
| 1 vCPU + 4GB vRAM |
• Standard • High • Full |
Baseline
|
Number of PUs as agreed with the customer. |
| Overage | Additional consumption above baseline. |
Equinix supplies 4 GB vRAM for each purchased vCPU and 1 vCPU for every 4 GB vRAM.
The minimum purchase quantity for EBC Flex is 8 PUs. This provides access to 8 vCPUs and 32 GB vRAM. Additional consumption is limited to 50% of the number of compute purchase units.
Calculation Example
Within the EBC environment, a guarantee value has been implemented per virtual data center (VDC).
You purchase 50 purchase units (PUs) in its VDC with a standard guarantee (1:4); this is 50 times 1 vCPU + 4 GB vRAM. You have deployed a VM of 5 vCPUs and 32 GB vRAM.
- This VM uses 8 PUs since the required memory determines the number of PUs. A VM with 5 vCPU and 20 GB vRAM uses exactly 5 PUs.
- In case of a purchase of a total of 50 + 25 = 75 PUs are available for consumption
- A baseline of 50 PUs applies to the settlement. The extra capacity consumed up to 75 PUs is charged separately as overage.
Using EBC Flex
You can choose the number of purchase units that suits your needs, referred to as the Baseline. If you need more resources during work or regular growth, you can immediately access additional resources. This additional consumption (overage) is automatically billed monthly.
The Equinix account manager can advise you on which purchase best suits your situation in the long term.
For EBC Flex variant, the additional consumption is limited to 50% of the number of purchase units and new VMs cannot be switched on when the limit is reached (number of purchase-units + additional consumption). A Self Service module is available in Service Now to increase the number of purchase units of your settlement. The increase of the available compute capacity according to the settlement is deployed immediately.
Within limits of the host, EBC Flex does not have a maximum size of a VM for the use of compute resources. For EBC Flex, the maximum recommended VM size is 8 vCPU and 64 GB vRAM.
