Mass-pricing of VMs
on Azure
based on CPU
cores count and memory. This is useful when costing a lift-and-shift migration dealing with many thousands VMS
of varied sizes.
The pricing is retrieved from Virtual Machines Pricing.
🚨 This tool will only provide you with an estimation. Depending on your Azure
spends you might be able to get a better deal from Microsoft
. You should use the output of this tool as a coarse-grain estimation. On top of the VM
price you will also need to consider storage and egress costs.
This tool is composed of two components:
- A Parser retrieving the pricing from Virtual Machines Pricing
- A Coster using the output from the
Parser
and a list ofVM
specifications to determine their price
This approach allows to decouple pricing acquisition from its usage and open the door to automation. The Parser
can be scheduled to retrieve the pricing at regular interval and the Coster
can then use an always up-to-date pricing.
Retrieve VMs
hourly pricing for a specific combination of culture, currency, operating system and region.

🚨 the parser is not - yet - able to retrieve pricing for the regions east-china2
, north-china2
, east-china
and north-china
as it is available on a different website.
🚨 the parser is not able to retrieve pricing for the regions us-dod-central
and us-dod-east
as no virtual machines are listed as publicly available.

Writes 2
output files in the out\

The parser has unit tests focusing on edge cases of price formatting:
> cd .\parser\
> yarn test
The end-to-end tests attempt to compare known prices for the windows
instance D2 v3
in us-west
using permutations of supported culture
and currency
:
> cd .\parser\
> yarn e2e
Price VMs
using the JSON
pricing files generated by the Parser
. The Coster
will select the cheapest VM
that has enough CPU
cores and RAM
.
.NET Core SDK 3.1
You should paste the JSON
pricing files generated by the Parser
in the Pricing\
folder. Setting the culture
is only relevant when dealing with pricing and input files that were written using another culture with a different decimal point (e.g. comma vs period).
In Release
mode:
> cd .\coster\src\AzureVmCoster
> dotnet run --configuration Release -- --input <input-path> --culture <culture>
> dotnet run --configuration Release -- -i <input-path> -l <culture>
> dotnet run --configuration Release -- -i <input-path>
The culture
is optional.
In Debug
mode
> cd .\coster\src\AzureVmCoster
> dotnet run --configuration Debug
Input file path: <input-path>
Culture (leave blank for system default):
You'll need to provide the <input-path>
when prompted, the culture
is optional.
<input-path>
should point to a CSV
file with the following fields:
- Region
- Name
- CPU (a
short
) - RAM (in
GB
, adecimal
) - Operating System
The columns can be in any order and the CSV
file can contain extra-columns. The Region
and Operating System
fields must match existing regions and supported operating systems in Azure
.
The Coster
will generate a CSV
file in the Out\
directory with the following fields:
- Region
- Name
- Operating System
- Instance
- CPU
- RAM
- Pay as You Go
- Pay as You Go With Azure Hybrid Benefit
