Regions and availability zones
Converge Cloud has one region, luzon, and two availability zones, of which clz-1 is the newest. The two zones do not offer identical instance types. Converge Cloud recommends verifying instance-type availability in the target zone prior to resource allocation.
Region
The only region on Converge Cloud is luzon. DescribeRegions returns exactly one entry. A request with any X-TC-Region value other than luzon fails with InternalError. Each request must include the X-TC-Region header; a request that omits the header also fails with InternalError.
| Region | State | Zones |
|---|---|---|
| luzon | AVAILABLE | 2 |
Availability zones
The only zone that offers CLOUD_HSSD disks, and the only zone in which the DR3 family is catalogued. M8A.45XLARGE1450 currently has Status SOLD_OUT in ncr-1 and SELL in clz-1.
Converge Cloud's newest availability zone. M8A is the only instance family in clz-1, and all 21 types currently have Status SELL.
Instance type counts
DescribeInstanceTypeConfigs returns the instance type catalogue. DescribeZoneInstanceConfigInfos returns purchasable configurations, with a Status field per row. The two counts differ because a catalogued type does not necessarily have a purchasable configuration. In ncr-1, the catalogue lists 29 types and 21 types are purchasable; the DR3 family accounts for the difference. DescribeZoneInstanceConfigInfos is the recommended action for determining what can be launched.
| Action | Returns | ncr-1 | clz-1 |
|---|---|---|---|
| DescribeInstanceTypeConfigs | Instance type catalogue | 29 | 21 |
| DescribeZoneInstanceConfigInfos | Purchasable configurations | 21 | 21 |
Every type, with its specification, is listed under instance types. The difference in ncr-1 is the DR3 family, which is catalogued but has no purchasable configuration. DR3 is not offered in any other zone.
Actions that describe a zone
Three actions describe what a zone offers.
| cvm:DescribeZones | The zones that exist, with the ZoneId of each zone. The response can also include zones that offer no instance types and no available block storage. |
| cvm:DescribeZoneInstanceConfigInfos | Purchasable configurations, with a Status of SELL or SOLD_OUT per type. Results can be filtered by zone with {"Name":"zone","Values":["clz-1"]}. |
| cbs:DescribeDiskConfigQuota | Block storage per zone. Inspecting the Available field is recommended, because a zone can list a disk type and still not offer it. |
Notes
Status is reported per zone and per instance type, and changes over time. M8A.45XLARGE1450 (180 vCPU / 1450 GB) currently has Status SOLD_OUT in ncr-1 and SELL in clz-1. An instance type that is unavailable in one zone is therefore not necessarily unavailable in the other zone. Converge Cloud recommends reading Status at request time rather than caching it.
ZoneId is a string; RegionId is a numberZoneId is returned as a string ("50010001"), while tke:DescribeRegions returns RegionId as an integer (50000001). The two identifiers are not interchangeable.
Converge Cloud has one region. cbs:CopySnapshotCrossRegions is available but has no second region to target, and cross-region redundancy is not offered. Availability-zone separation within luzon is the only form of geographic redundancy.
