Digital Marketplace overview
The Digital Marketplace helps you find cloud technology and specialist services for digital projects.
It uses 3 frameworks (agreements between government and suppliers). You can find:
- digital outcomes, digital specialists and user research services through the Digital Outcomes and Specialists framework
- cloud services (for example, cloud hosting, software and support) through the G-Cloud framework
- physical data centre space through the Crown Hosting framework
All public sector organisations, including agencies and arm’s length bodies, can use the Digital Marketplace.
The Crown Hosting framework
The Crown Hosting framework is a contract between the Cabinet Office and a supplier called Crown Hosting Data Centres Limited to provide colocation data centre services (physical data centre space). Any public sector organisation can occupy the data centres provided without further competition through an access agreement with Cabinet Office.
Crown Hosting Data Centres Limited is a joint venture between the Cabinet Office and Ark Data Centres Limited.
Crown Hosting is principle 4 of the government’s Cloud First policy, providing physical data centre space for private cloud and legacy technology where the dependent business applications are not delivered from public cloud. This cross-government framework ensures that these applications can continue to be hosted for as long as is necessary, cheaply and securely.
