Using a db size of 10Gb, and 10% writes and 90% reads. Provisioned databases are for 1 year. For AWS SimpleDB the amount of CPU is hard to quantify, so I used the following formulae (0.248+((requestsPerSecond)/1.5*0.14))*usdgbp This matches closly to Azure Table Storage, which is to be expected. Here are the results: (click on image to view) (click on image to view) Zooming into the lower end (click on image to view) Download Azure-CosmosDB-pricing.xlsx spreadsheet here . Summary:   Both AWS and Azure are similar in NoSQL pricing. For the small companies out there needing the cheapest NoSQL options there is Azure Table Storage and AWS SimpleDB .

Setting the PowerShell execution policy - the trap

-
I was recently pulling my hair out trying to run a powerShell script in VisualStudio. I kept getting the error: "File SomeScript.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details." So I ran the script: powershell set-executionpolicy remotesigned Tried a gain, and still it fails! Only until I spoke to my developer collegue Damian Powell did he say you actually have to run that command for both x86 and x64 powershells. So I ran: C:\Windows\System32\WindowsPowerShell\v1.0\powershell set-executionpolicy remotesigned C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell set-executionpolicy remotesigned Hey presto! All works. Thanks Damian!
