How to understand the new flavor naming rules for the 2017 range?

FAQ on naming rules for the 2017 Public Cloud offers


The 2017 range brings with it a new standardization for flavor names.

The first letter indicates the instance type

The "General Purpose" category provides a balanced CPU/RAM ratio on instances to meet most needs. It is the former EG category, and their names will begin with a B in the new range. E.g.: B2-7.

"CPU Optimized" instances are powered by a Xeon E5 processor and have a high number of cores. This is particularly suited to cases where computing power is a priority. It is the former HG category, and their names will begin with a C for "CPU" in the new range. E.g.: C2-60

"RAM Optimized" instances have a large amount of memory to better address the needs of databases and other memory-intensive applications. It is the former SP range, and their names will begin with a R for RAM in the new range. E.g.: R2-240

The second character is for the generation

The second character simply corresponds to the generation of the range. As 2017 is the second generation for most of the instance types, the number is 2.

The last part

The last part to the right of the "-” indicates the amount of RAM.
