Hosting & Infrastructure (DSCR)

TypeOverarching Standard
Effective Date


Framework(s)Digital Social Care Records
Traceability Matrix


Supports best practices for infrastructure and hosting of systems. For example, ensuring that systems are cost effective, secure and energy efficient.

It is essential that Solutions delivered under the Catalogue or the Catalogue Agreement (the Framework)follow standards and guidance that are cost effective, secure, reliable, resilient, safe, manageable and energy efficient. In addition it is a Supplier's responsibility to ensure they fully understand industry standards and best practice and cannot rely on the Authority explicitly defining requirements at a point in time. The UK Government promoted a 'Cloud First' policy and since 2018, hosting within a public cloud has become a reality for health based services. The Technology Strategy has a fundamental principle of delivery of services via cloud provision and specifically the architecting of Solutions to be cloud native. The Authority recognises that cloud hosting may not be appropriate for some services e.g. based on the sensitive and scale of data or the manner in which the service is architected.

Fundamentally there are three core options for hosting services:-

For Digital Social Care Records (DSCR) Suppliers, only Cloud hosting Standards are applicable.

Hosting OptionDescriptionPreference StatusLevelSection
Cloud – Public or PrivateThe Public / Private cloud provider offers self-managed virtualised, elastic/on demand scalable infrastructure as a service where the cloud provider owns the underlying data centres and physical infrastructure. The Supplier rents the use of the virtualised infrastructure.Strongly Preferred

Suppliers SHOULD host Solutions via one of these options.

NHS Cloud Hosting Standards & Guidance


The physical infrastructure is owned by the Supplier and hosting of the physical infrastructure is provided within the Colo providers data centres, The management of the infrastructure can be done by the Colo provider, a 3rd party or the Supplier themselves.


Colocation & Provider Data centre Standards

Provider own facilitiesThe data centres and physical infrastructure are owned by the Supplier. The management of the infrastructure can be done by a 3rd party or the Supplier themselves.Not recommended

The Authority does not recommend the Suppliers should attempt to host services themselves due to the cost and complexity of providing data centre capabilities that meet the necessary requirements.

Given the potential security and service risks associated with the local hosting of services, the Catalogue or the Catalogue Agreement (the Framework) will not formally assure it. Buyers purchasing services which are locally hosted will be required to satisfy themselves that the security and service risks are mitigated and managed appropriately.

The Standards to support infrastructure and hosting are split into two sections, depending on the mechanism being deployed:-

  • Cloud – Based on published NHS wide risk assessments and guidance.

  • Colocation / provider facilities – specific requirements and assurance processes.

NHS Cloud Hosting Standards & Guidance

The following is a summary of the "NHS and social care data: off-shoring and the use of public cloud services" gathered from cloud guidance information published by the Authority. It makes clear what evidence is to be sought from a Supplier, where it is deemed necessary to assure compliance with the 4 step process.

Some key points of note:

  • All decisions in relation to the security of data are the responsibility of the data controller(s). Also, in many cases Organisations will have a Senior Information Risk Owner responsible for data and cyber security.
  • Where a professional body exists, there is certainly merit in seeking their approval for the migration of data to cloud, but ultimately the data controller remains the key approver.
  • Data Controllers need to understand the risks of moving to cloud, and any impact.
  • Data controllers must take into account the standard CIA triad (Confidentiality, Integrity, Availability), and also other relevant factors, including, but not limited to, cost, security, resilience, capability and funding.

The 4 steps to inform the data controller on a risk based decision are detailed below.

Step 1 - Understand the data

All data managed by Health or Care Organisations should be treated as OFFICIAL or OFFICIAL-SENSITIVE data, in line with the Government Security Classification Policy.

The Authority has further elaborated the very broad classifications. The Health and Social Care Cloud Risk Model is more granular than the Government Security Classification Policy.

EVIDENCE requested for step 1:

  1. The Supplier needs to provide evidence that they have identified all data, data types, and attributes, and assessed it against the model.
  2. Binary objects identified within the data set, such as JPEG, PDF, etc, can still be classified by their content. The Supplier needs to evidence an understanding of the percentage splits between data types, which may alter the overall the classification.

Step 2- Assess the Risks

The Authority's Health and Social Care data risk framework and associated data risk model are both used to establish the risk level of the data. Typically Personally Identifiable Data (PID) would be Level 5. Please refer the link NHS and social care data: off-shoring and the use of public cloud services for latest versions of Cloud risk framework and Health and social care data risk model.

EVIDENCE requested for step 2:

  1. Completed risk model indicating the risk level established from the data detailed in step 1.
  2. The Health and Social Care Cloud Risk Model also considers service classification (Bronze/Silver/Gold/Platinum), and Suppliers will need a statement to back-up their selection of the classification.

Step 3 - Implement the appropriate controls

Health or Care Organisations, such as a GPs, retain the data controller responsibilities and they are therefore ultimately responsible for ensuring that proportionate controls are put in place to mitigate all risks. The data controllers may rightly request to see these controls (proposed by the Supplier) before considering any migration to cloud.

EVIDENCE requested for step 3:

  1. The Supplier will provide evidence against section 8. Appendix A - detailed advice and guidance from the latest version of "Cloud security good practice guide" present in NHS and social care data: off-shoring and the use of public cloud services with a statement (or linked evidence) against each guidance line item which is applicable for the data classification level identified at step 2.
  2. Prior to implementation - where there are many data controllers using a Solution (such as a GP or Care Home system), the Authority would request evidence of the comms strategy to inform all data controllers, seeking any dissent based on the identified risk.
  3. Prior to implementation - consideration around GDPR: The Supplier should state they have completed and provide if requested to the Catalogue Authority, a Data Protection Impact Assessment (DPIA), plus confirm adherence to the relevant data protection legislation.

Step 4 - Monitoring the Implementation

All cloud providers take on data processor responsibilities, with Heath or Care Organisations (e.g. GP practices or Care Homes) retaining the data controller responsibilities, and they must ensure the selected cloud provider remains fit for purpose.

Clearly where compliance is being undertaken by the Authority, the data controllers will likely be relying on the Authority's ongoing involvement e.g. NHS Security team are working annually with cloud providers to validate their industry standards compliance, including areas such as penetration testing.

EVIDENCE requested for step 4:

  1. Within a contractual framework, such as GP IT Futures, Suppliers will be obliged to evidence any external accreditations at the point of renewal. This will include those external standards evidenced during step 3.

ES10.0EU Code of ConductEUCoC

This Code of Conduct has been created in response to the increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres. The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practices and targets.

TBD: May be put on the roadmap.

BS EN 50600-2-1:2014. Building construction

(Minimum availability class 3)

BS EN 50600-2-1:2014

The unrestricted access to internet-based information demanded by the information society has led to an exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres are housing and supporting the information technology and network telecommunications equipment for data processing, data storage and data transport. They are required both by network operators (delivering those services to customer premises) and by enterprises within those customer premises.

Data centres need to provide modular, scalable and flexible facilities and infrastructures to easily accommodate the rapidly changing requirements of the market. In addition, energy consumption of data centres has become critical both from an environmental point of view (reduction of carbon footprint) and with respect to economical considerations (cost of energy) for the data centre operator.

The implementation of data centres varies in terms of:
a) purpose (enterprise, Colocation, co-hosting or network operator facilities);
b) security level;
c) physical size;
d) accommodation (mobile, temporary and permanent constructions).

The needs of data centres also vary in terms of availability of service, the provision of security and the objectives for energy efficiency. These needs and objectives influence the design of data centres in terms of building construction, power distribution, environmental control and physical security. Effective management and operational information is required to monitor achievement of the defined needs and objectives.

This series of European Standards specifies requirements and recommendations to support the various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructures within data centres. These parties include:
1) Owners, facility managers, ICT managers, project managers, main contractors;
2) Consultants, architects, building designers and builders, system and installation designers;
3) Suppliers of equipment;
4) Installers, maintainers.

Formal accreditation against BS EN 50600 will not be available until mid 2019 therefore Suppliers MUST be able to provide evidence to demonstrate alignment with the scope and aims of BS EN 50600.

Note: Formal accreditation (when available) will become a mandatory requirement as detailed in the standards road map
