CSP Rolling 6-Month CMGR

CMGR means “compound monthly growth rate.” This CMGR metric shows the growth of each region of the CSPs we track. This measure of size is a factor of the number of instance type families offered in the region and the number of sizes offered in each type family (specific core counts and memory configurations). Because we scan these CSPs monthly, we are able to calculate changes in this metric from month-to-month.

Regions with larger CMRG are shown with larger icons. Positive and zero CMGR values are shown by a solid circle, negative CMGR values are shown by a solid square. Every active CSP region has a CMGR value.

Bare Metal Servers

Bare metal servers are specific instance sizes that reserve all of a physical server (the server “hardware”). Each instance type is based on a physical server specification–a specific model of processor that has a known number of cores with a specific total system memory that determines the type’s memory per core profile. Bare metal servers reserve the maximum specifications available for a type and are often offered without an operating system.

A large solid dot indicates that bare metal servers are available in that region. A small empty circle indicates that no bare metal servers at all are present in that region.

Accelerator Classes

We divide compute accelerators into four classes based on the architecture they use to accelerate math-intensive code. We show where these architectures are available for each CSP and region. See below for accelerator class definitions.

Circle size denotes the number of accelerator classes available in a region. A small empty circle indicates that no accelerators are present in that region.

Zones

Zones, also known as availability zones, are physically separated locations within a CSP's region. By providing separate zones, CSP's can mitigate failures at any one zone within a region. Failures can result from issues with software and hardware, but also from natural events such as floods or fires. Some regions may have only one zone, but larger regions can have five or more regions to support their customers.

Circle size is relative to the number of zones in the region. A larger circle represents more zones.

Accelerator Brands

We record many details about tracked CSPs’ IaaS accelerator options. We show accelerator chip vendor brands and general model numbers of the chips offered by tracked CSPs in each region. See below for a complete list of accelerator manufacturers and brands currently deployed by tracked CSPs.

Circle size denotes the number of accelerator brands available in a region. A small empty circle indicates that no accelerators are present in that region.

Redundancy

Consistent with Zones count, this measure identifies all the regions with more than one zone, thereby having the ability to offer redundancy within the region. Redundancy is important for companies wanting to mitigate their applications for failures within any given zone.

Circle size is relative to the number of zones in the region. Unlike the zone count, the redundancy only shows a large circle for any region with more than one zone within the region.

Processor Brands

We record many details about tracked CSP’s IaaS processor options. We show processor chip vendor brands and the generations of those brands offered in each region. See below for a complete list of processor brands currently deployed by tracked CSPs and a list of which processor generation code names we compare to each other.

More processor brands available in a region are shown with larger circles.

Compute Cost Index

The Compute Cost Index allows from easy comparison between regions for general price. Any product may vary from one region to another, but this index provides a reasonable guide for general price differences between regions. The price is based on the geometric mean of the on-demand price in US Dollars for 8-core compute instances within a given region. The prices are measured across all cloud providers for easy comparability. The lowest value is 1.0. All other regions are priced relative to that lowest-priced region.

Circle size is relative to the calculated price. A larger circle represents a higher price.
