Ubuntu Pro Description

Introduction

Ubuntu Pro is a subscription that gives you an additional stream of security updates and packages that meet compliance requirements, such as FIPS or FedRAMP, on top of an Ubuntu LTS. For support and managed solutions customers, it also includes expert support for troubleshooting, break-fix and bug-fix on the full open-source stack or on its subset (Infra-only).

As a customer, you are entitled to the following coverage, depending on the appropriate support level on a per-machine basis.

Each subscription can cover one or more:

  1. Physical server: The subscription is attached to a physical host. Where all physical hosts in an Environment are subscribed, the subscription also applies to Ubuntu Guests in the Environment that are operated by the subscriber for the subscriber's internal business purposes.
  2. Virtual machine: The subscription is attached to an Ubuntu virtual machine or automatically attached at launch under a public cloud (Google Cloud, AWS, Azure, etc.). This subscription covers Ubuntu images running on virtual machines or in containers.
  3. Desktop: The subscription is limited to a machine with Desktop use cases. It can also cover Ubuntu on Windows Subsystem for Linux (WSL) and developer tools such as MicroK8s, Data Science Stack and Multipass.
  4. Device: The subscription is attached to a physical device for Device use cases including customer's hardware that has been certified or enabled by Canonical.

Each subscription can be purchased at one of three support levels:

  1. self-support
  2. support (weekday)
  3. support (24/7)

and must cover all Ubuntu systems within an Environment.

Additionally, the subscription might cover the full stack (Ubuntu Pro), or just the infrastructure subset of the stack (Ubuntu Pro (Infra-only)). Unless otherwise stated, a subscription will be Ubuntu Pro.

Detailed pricing can be found at: https://ubuntu.com/pricing/pro

Ubuntu Pro subscriptions are governed by the terms at https://ubuntu.com/legal/ubuntu-pro-service-terms unless otherwise agreed in writing with Canonical.

Support Services Process

11. Service initiation

  1. Upon commencement of the services, Canonical will provide access for a single technical representative to Landscape, the support portal, and the online Knowledge Base
  2. The customer, through their initial technical representative, may select their chosen technical representatives who act as primary points of contact for support requests. The customer will receive up to 5 dedicated, personalised credentials for technical representatives per every 500 nodes or 50,000 devices under support, but not more than a total of 15 credentials
  3. The customer may change their specified technical representatives at any time by submitting a support request via the support portal

12. Submitting support requests

  1. The customer may open a support request once the customer account has been provisioned within the support portal
  2. The customer may submit support cases through the support portal or by contacting the support team by telephone, unless otherwise noted
  3. A support case should consist of a single discrete problem, issue, or request
  4. Cases are assigned a ticket number and responded to automatically. All correspondence not entered directly into the case, including emails and telephone calls, will be logged into the case with a timestamp for quality assurance
  5. When reporting a case, the customer should provide an impact statement to help Canonical determine the appropriate severity level. Customers with multiple concurrent support cases may be asked to prioritise cases according to severity of business impact
  6. The customer is expected to provide all information requested by Canonical as we work to resolve the case
  7. Canonical will keep a record of each case within the support portal enabling the customer to track and respond to all current cases and allowing for review of historical cases

13. Support severity levels

  1. Once a support request is opened, a Canonical support engineer will validate the case information and determine the severity level, working with the customer to assess the urgency of the case
  2. Canonical will work to provide the customer with restoration of the issue, i.e. a temporary work-around or a permanent solution, following the severity levels as described below. As soon as the impacted core functionality is available, the severity level will be lowered to the new appropriate severity level
  3. Canonical will use reasonable efforts to respond to support requests made by the customer within the initial and ongoing response times set forth below, based on the applicable service and severity level, but cannot guarantee a work-around, resolution or resolution time

1 Included with all Ubuntu Pro subscriptions
2 Business hours: 8:00 AM to 5:00 PM at the Customer’s location as set in the Canonical Support portal. Weekends are not included.
3 Canonical Support will provide follow-up updates within defined time frames after responding to a customer inquiry. These ongoing response time frames are defined based on the severity level of the issue, and counted from the time of the latest severity update.

14. Customer assistance

  1. Continuous effort support is dependent on the customer being available at all times to assist Canonical, otherwise Canonical may need to reduce the severity level and its ability to respond accordingly

15. Hotfixes

  1. To temporarily resolve critical support cases, Canonical may provide a version of the affected software (e.g. package) that applies a patch. Such versions are referred to as “hotfixes”. Hotfixes provided by Canonical are supported for 90 days after the corresponding patch has been incorporated into a release of the software in the Ubuntu Archives, or Canonical hosted store.
  2. A patch may be rejected by the applicable upstream project, in which case the hotfix will no longer be supported, and the case will remain open. The final fix will be provided when the upstream accepts it and incorporates it into a release of the software. The customer should update the software to the new release including the stable fix

16. Support language

  1. Canonical will provide the support in English unless specified otherwise

17. Remote sessions

  1. At the discretion of a Canonical engineer, a remote access service might be offered to access a supported system. In such a case, Canonical will determine which remote access service to use. Canonical engineers expect to have read-only access and do not perform any remote actions on a supported system

18. Ask for a Peer Review

  1. As a normal business practice, Canonical performs peer reviews on a percentage of all cases. Customers can specifically request a peer review on a case within the case comments or by calling the phone number listed in the support portal. An impartial engineer will be assigned to review the case and provide feedback

19. Management escalation

  1. The customer may escalate support issues following the escalation process:
    1. Non-urgent needs: Request a management escalation within the case itself. A manager will be contacted to review the case and post a response within 1 business day
    2. Urgent needs can be escalated to Canonical’s Support Engineering Management by emailing support-manager@canonical.com. If you require further escalation, email Canonical’s Support Director at operations-director@canonical.com

20. Levels of Support

  1. Canonical provides Support at the following levels:
    1. Level 1 Support: Assistance in troubleshooting and restoring your broken application
    2. Level 2 Support: Troubleshooting and break-fix of defects that are rare or need advanced knowledge to resolve. Typically advanced functionality, advanced configuration, or unexpected behaviour
    3. Level 3 Support: Complex defects involving bug-fixes on Ubuntu and upstream software. Complex defects involving either core functionalities unavailable, severely degraded, or a complex configuration failure with respect to solely Ubuntu and OpenStack as deployed using Canonical’s tooling (Juju and MAAS)

Add-Ons

  • Service conclusion. At the end of the service term, the Managed Service will initiate an operational transfer. Operational transfer includes:
    1. Hand over of all credentials of the hosts, management software, Landscape and Applications to the customer. The continued operation of Landscape is subject to purchase and agreement of appropriate licence terms
    2. Coordination of any applicable training (if purchased)
    3. For self-deployed applications, Managed Services will transfer the access to the environment’s resources exclusively to Customer. This cannot be undone, and future deployments will use the most current component version which may cause incompatibilities with decommissioned Environments.
  • Customer dependencies. Managed Services requires:
    1. Credentials to the Infrastructure being used for the Applications in the case in which such infrastructure is not managed by Canonical (i.e. Managed OpenStack)
    2. Continuous VPN access for Canonical support personnel to the Environment
    3. For self-deployed Environments, continuous access to the Environment’s resources
    4. Utilisation parameters per Node to be kept below the maximum specified in the design document provided by Canonical when the Environment is delivered to the customer
    5. The facility where the Environment is hosted to comply with the minimum required measures to function, including but not limited to, connectivity, sufficient power supply, sufficient cooling system, and physical access control to the Environment
    6. The entire Environment to be covered by Managed Services
  • Minimum size requirement. Managed Services can only be provided for Environments with:
    1. At least 12 deployed nodes for any eligible OpenStack release
      1. At least 9 deployed nodes for any other compatible product
      2. For Environments deployed directly from public cloud marketplaces, there is no minimum size requirement.
  • Uptime service level
    1. The Managed Service includes the following uptime service levels:
      DATA PLANE FOR CUSTOMER WORKLOADS THAT ARE DISTRIBUTED ACROSS TWO REGIONS DATA PLANE FOR CUSTOMER WORKLOADS THAT ARE IN A SINGLE REGION CONTROL PLANE (OPENSTACK/KUBERNETES API, WEB UI AND CLI)
      Uptime 99.9% 99.5% 99%
    2. Data plane includes:
      1. Virtualisation (for workloads that are architected to not depend on a single compute node)
      2. Storage (block & object)
      3. Network for instances
    3. Downtime must be directly attributable to Canonical in order for it to count against the service level and is measured across a 12-month period. Planned maintenance windows and any requests by the customer are not taken into account when calculating uptime. Planned maintenance is carried out as required by Canonical, Monday to Friday during Canonical working days
