Onboarding and offboarding

Onboarding and offboarding
Getting started We provide an initial conference call and WebEx with clients to provide portal training and understand any questions the client has.

There is also online documentation available and our support desk is available 24/7 to provide further assistance during deployment.

End-of-contract data extraction Users can request an export of their VMs and storage in order to extract data on the platform.

Exports can be done from the last complete snapshot or by shutting the VM down for a clean export of live data. Exports are typically provided in RAW format but can also be supplied in OVF/OVA formats.
End-of-contract process Included with the price is a decommission of the virtual machines and cloud environment including secure data deletion.

If exports of VMs are required then these can be provided at an additional cost. Exact costs will depend on the number of VMs and total storage.

Using the service

Using the service
Web browser interface Yes
Using the web interface Users can use the online web portal to provision new resources instantly (VMs, storage and networking) as well as manage deployed resources through changing VM configurations and resource allocation on the fly, performing instant backups, configuring CDNs and managing firewall rules.

The web portal also provides access to all real-time and historical logging for the environment along with an audit trail of user actions.
Web interface accessibility standard None or don’t know
How the web interface is accessible The web portal is responsive and allows for resizing of text / images without loss of definition. All embedded images also have correct alt-text tags for screen readers.
Web interface accessibility testing We have not done any testing on the web interface.
What users can and can't do using the API Users can fully manage the service through the API interface. API keys are generated through the online portal and IP authorisation is controlled by the whitelist of IP addresses for the user the key is generated under.

All functions of the platform that are available to the user through the web portal are exposed through the API.

The API is RESTful.

Availability and resilience

Availability and resilience
Guaranteed availability We provide an SLA for 99.95% web interface uptime and 99.95% hypervisor host uptime. All VMs will hot-migrate in the event of a physical host failure.

In the event of an SLA breach users can claim credits against their invoice charges by contacting their account manager.
Approach to resilience All equipment is dual PSU with bonded network connections. We operate a KVM cluster with hot-migration of VMs between physical hypervisor hosts. All storage is provisioned on dual controller RAID-10 SANs with hot-standby disks and the ability to hot swap drives.

We operate the platform across our two UK data centres and are able to support the migration of VMs between platforms if required.

All data centre power is UPS and generator backed (tested monthly with full building load) and all networking is provided over physically diverse fibre that is lit and managed by 4D.

Full information and design documentation is available on request.
Outage reporting We provide outage notifications through our ticketing system which will issue an email to affected users along with an online status page to which regular updates are posted by the engineering team.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach All changes are split into pre-approved changes or major changes.

All changes (PAC and major) require the completion of a change request which looks at the technical, commercial and security impacts of a change. Changes are reviewed by the change board before being approved or denied.
Vulnerability management type Supplier-defined controls
Vulnerability management approach We operate a centralised patch and security management system to identify new patches which need rolling out.

We also have annual penetration and vulnerability assessments (both external and internal) on our systems.
Protective monitoring type Supplier-defined controls
Protective monitoring approach We identify potential compromises through proactive penetration and vulnerability scanning, proactive monitoring of systems behaviour as well as our internal incident reporting process.

In the event a potential compromise is discovered we will review the incident internally and aim to have an initial response within 24 hours.
Incident management type Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach We have processes in place for predefined incidents.

Users are able to report incidents, or suspected incidents, through the online incident reporting portal and these are fed back into into our incident review teams as well as the security forum.

Reports are provided externally on an as needed basis or when an incident needs to be reported to a regulatory body.
