1.1 Terminology

Pay-As-You-Go(PAYG)The fee calculated by (i) usage time x “per use” price in the ECL Price List” or (ii) usage volume x “per use” price in the ECL Price List” in one Fee Month will be “Monthly Charge”.
Capped Pay-As-You-Go(PAYG)The upper limit of a plan’s Monthly Charge is called Cap.

If Monthly Charge ≧ Cap, Cap will be applied as Monthly Charge.

Capped Pay-As-You-Go(PAYG) (Plan change allowed)A capped Pay-As-You-Go(PAYG) plan and its Monthly Charge is calculated as

(i)Compare the charge amount for a plan’s duration with its Cap for the same duration and take the smaller one as the duration fee.

In case that there are multiple plan changes during a billing month, the sum of duration fees for the durations of ‘same plan’ is treated as the duration fee of the plan.

(ii)Compare the total of the duration fees calculated by 1. with the largest Cap in the plan’s change history during a billing month and take the smaller one as the Monthly Charge.

Monthly FixedThe Monthly Charge does not depend on the usage duration, it is fixed charge amount plan.

In case that there are multiple (n-times) starts-and-terminations during a month, then Monthly Charge will be n x Cap

1.2 Service menu vs. Charge Pattern

To understand the charge amount over your ECL2.0 usage, you need to identify the charge pattern behind your usages. You can find the mapping between an ECL2.0 service menu and its charge pattern in ECL2.0 pricing list and the table shown below.

Chapter 2 ECL2.0 Charge Patterns

This chapter is intended to explain ECL2.0 charge calculation patterns. We will run through each of the patterns with examples.

Related resources:
For the description of each ECL2.0 services, please refer to our Service Description available at our Knowledge Center.
For information on the price of an ECL2.0 service menu and the pricing calculator, please refer to our pricing/
pricing calculator page at our Knowledge center.

2.1 Pay-As-You-Go(PAYG)

Charge amount in this pattern will increase along with the growth in usage without upper limitation.

FormulaCharge Amount Usage x Per Use

There are cases in Pay-As-You-Go(PAYG) that the ‘Size’, ‘Time’ in the ‘Contents’ field show rough indication due to round up.
The exact value in the ‘Usage’ field is used for ECL2.0 charge calculation.

2.2 Capped Pay-As-You-Go(PAYG)

Charge amount in this pattern will increase along with the growth in usage but stay at its upper limitation(CAP).

FormulaCharge Amount minUsage x Per Use, CAP

Extra Explanation  for Capped Pay-As-You-Go(PAYG):
In ECL2.0, some Pay-As-You-Go(PAYG) menus have maximum Monthly Charge amounts, called “CAP”.

If the usage duration of a Pay-As-You-Go(PAYG) resource reaches approx. 28 calendar days, charge amount over the resource will stay at CAP (see the picture below).

2.3 Capped Pay-As-You-Go(PAYG) (Plan Change)

In case of plan changes,  charge amounts for each duration are calculated at first (Phase  I) and then the smaller one between the sum of all duration charges  and  the max. CAP of the underlying resource is chosen to be the Monthly Charge amount (Phase II).  This is called 2-phases CAP in ECL2.0.


Phase I:   Amount_1 minUsage1 x Per Use1, CAP1)                       … before  

                 Amount_2 minUsage2 x Per Use2, CAP2)                       after

Phase II: min (Amount_1 + Amount_2, max(CAP1, CAP2))


Along with the change in plan(flavor),  the license fee of  the OS installed on the Compute also changed accordingly.

2.4 Monthly Fixed

Some menu, like OS for Barematel server, charges fixed amount per month.

FormulaCharge amount = Fixed, usage duration independent.

2.5 Special Charge Calculation for some menus

There are some special calculation methods for some menus. Please refer to the examples below.

2.5.1 Capped Pay-As-You-Go(PAYG)(Logical NW)

In case of Logical network, the monthly fee charges with the capped price per month, which is based on the total usage time by Customers within the month.
This menu provides equivalent to five Logical Networks free of charge, i.e., the Charge of maximum five Logical Networks (Maximum Monthly Charge) will be deducted from Customers’ overall charge of Logical Network.

2.5.2 Monthly Fixed (CIC)

A monthly fixed charge menu with the feature that the charge of 1 colocation connection (CIC)/1Gbps will be free.


Charge amount = (count(CIC Links) – 1) * CAP

Where ‘-1’ means   1CIC link (1 Gbps) per Tenant is free-of-charge.

Note:   10 Gbps CIC is out of the scope of 1 link free-of-charge.

2.5.3 Monthly Fixed(Guest Image)

In case of Windows Server under the Guest Image menu, charge amount depends on the number of the underlying VMs.


Monthly Charge = (7 VMs and less) “CAP” x “# of VM” or

                                 (8 VMs and more) “CAP(8VM~)”

2.5.4 Oracle(Capped Pay-As-You-Go(PAYG) + Monthly Fixed)

Billing structures

Monthly bills with capped metered uppermost maximum (per minute).

2-phase caps will be the capped meter this menu will integrate.

For Windows, fixed monthly fee will be added in addition to the above.

2.5.5 SQL Server(Monthly Fixed)

The pricing system differs for Virtual server/Dedicated Hypervisor.

Virtual serverThe fee is charged based on the Virtual Server flavor.

If the customer uses multiple flavors within the month, the cost will be based on the flavor with the largest number of vCPUs.

Dedicated hypervisorThe fee is charged based on the number of vCPUs of the guest OS.

If the customer changes the number of vCPUs within the month, the cost will be based on the largest number of vCPUs.

2.5.7 Cloud Foundary(Capped Pay-As-You-Go(PAYG))

Cloud Foundry (PaaS) usage volume is counted by calculating the usage volume of active instances over their durations(add・remove・suspension)  in a billing month in a different way with other ECL2.0 menus.

In case that you need to confirm your Cloud Foundry (PaaS) charge amount , please contact your local sales representatives.

PlanMonthly FeesSupplementary Remarks
Shared CFMonthly uppermost maximum added metric rate at each second.

Operable hours of application will be the billing subject; therefore, at such hours the application is not in duration, no charge will be added.

For each Tenant, Instance use for every hour will be calculated and which will subsequently become the subject of bills, worth 500 hours of timetable unit will be the subject of the bill. Since it is fixed flat rate, Customers’ use for more than 500 hours will be billed at no charge.

*If there is rounding error during calculation, it will be rounded down.

Virtual Private CFMonthly bills with capped metered uppermost maximum (per minute).

Regardless of whether applications are running, customers will be charged based on the numbers of CF Routers and Cells.

Since subscription of a new environment and the applications migration are required to update the Cloud Foundry itself, basic rates of the second environment shall be free for initial 30 days in case of a subscription of a second Virtual Private CF environment within the same tenant. It will be charged, however, even for initial 30 days for a third environment and beyond.

*If there is rounding error during calculation, it will be rounded down.
