This Freedom of Information request asks for information regarding Ordnance Survey's Cloud infrastructure.

Request for information - Ref No: FOI231146

Request

Thank you for your email of 25 April 2023, requesting information from Ordnance Survey in accordance with the Freedom of Information Act (FOIA) 2000, as set out in the extract below:

“Under the Freedom of Information Act, I would like to request the following information:

  1. The duration of time the Ordnance Survey has been utilising cloud infrastructure.
  2. The criteria used to choose a cloud provider.
  3. The percentage of infrastructures in the Ordnance Survey employing cloud services.
  4. The supplier of cloud infrastructures used by the Ordnance Survey. (AWS/Oracle/Azure etc.)
  5. Case studies highlighting the successful implementation of the 'Cloud-first' strategy.
  6. The uptime of the Ordnance Survey cloud infrastructure.
  7. The annual budget over the last five years for IT-managed services.
  8. Please provide the percentage spent on cloud managed services”

Our response

Taking each request in turn, I confirm the following:

1. The duration of time the Ordnance Survey has been utilising cloud infrastructure.

The first (minimal) use of public cloud services was for our free API offerings in 2009. This was on Amazon Web Services (AWS). OS used its free Microsoft Azure allowance from 2012 for the “Download Service”.

2. The criteria used to choose a cloud provider.

It is our understanding of your request that you are referring to a provider of public cloud services for general compute and not SaaS services for employee management, M365 or D365.

  • In order to fairly select a cloud provider, OS issued a tender for consultancy. The tender required companies responding to be gold partners or equivalent with Azure, AWS and Oracle, but otherwise be independent of those providers.
  • This consultancy concluded in 2017 with a primary recommendation for Azure.
3. The percentage of infrastructures in the Ordnance Survey employing cloud services.

This information is not held as it is not recorded in the format requested.

4. The supplier of cloud infrastructures used by the Ordnance Survey. (AWS/Oracle/Azure etc.)

  • Primarily Microsoft Azure.
  • Some use of AWS.
  • Apigee is used for API management.

5. Case studies highlighting the successful implementation of the 'Cloud-first' strategy.

This information is not held.

Under the duty to provide information and assistance in accordance with section 16 of FOIA, we can provide the following information which may assist you in this matter:

Ordnance Survey’s focus is geospatial data and case studies we hold are based around the benefits of geospatial data rather than cloud, they are published on our website ‘Insights’

6. The uptime of the Ordnance Survey cloud infrastructure.

This information not held.

Under the duty to provide information and assistance in accordance with section 16 of FOIA, we can provide the following information which may assist you in this matter:

We consider individual services, rather than the cloud infrastructure as a whole. Additionally, services may be in Azure, AWS, on-site or as SaaS services.

The below tables, detail information for the past 24 months for some representative and key systems in the public cloud (Azure).
