    Platform management

    UKCloud for OpenStack is managed directly by the customer, using OpenStack's Horizon dashboard, the UKCloud Portal, and APIs associated with both.

    Service provisioning

    You can request UKCloud for OpenStack via your Service Delivery Manager or by using the My Calls section of the UKCloud Portal.

    Within 4 business hours of accepting an order, UKCloud will create the customer's Primary Administrator account and send a Welcome Pack which includes the URL for the UKCloud Portal, and the Getting Started Guide.

    Customer responsibilities

    The control and management of access and responsibilities for end users including appropriate connectivity, security and accreditation if required. If access is required over government secure networks such as HSCN, Janet, RLI or PSN (including legacy networks), the customer is responsible for adhering to the Code of Connection.

    Self-managing the environment including VM deployment, virtual network configuration, storage management, and so on.

    Maintaining a master copy or backup copy of the data used in the UKCloud for OpenStack service.

    Ensuring only appropriate data (for example OFFICIAL) is stored and processed by applications on this environment and that they comply with the UKCloud Security Operating Procedures (SyOps) and other Information Assurance requirements as specified in the UKCloud System Interconnect and Security Policy (SISP) and associated accreditation documentation sets.

    Default network limits

    By default, we will place the following network limitations per project:

    • 3 x Floating IP Addresses

    • 2 x Network Routers

    Customers with requirements beyond these limits can raise a service request via My Calls to have these limits per project considered for raising.

    Compute virtual resource limits

    By default, we will place the following virtual resource limitations per project:

    • 100 Instances

    • 100 vCPU

    • 200 GiB RAM

    • 2 TiB Persistent block storage

    Customers with requirements beyond these limits can raise a service request via My Calls to have these limits per project considered for raising.

    Block storage volume limits

    Due to a current constraint within the OpenStack project, a maximum total of 25 block storage volumes (Tier 1 or Tier 2) can be attached to each OpenStack instance.

    Platform operation request limits

    Although designed to be a large-scale cloud platform, we strongly advise that when performing operations/requests against UKCloud for OpenStack you perform these actions in batches of no more than 30 (for example, only creating batches of up to 30 new instances in a single request). Additional requests can then be made to the platform for subsequent batches.
