End-of-contract data extraction
Data created by the system or its applications would still be stored in a
customers provisioned storage in its native format. Customers therefore
can simply continue to use the data connected to the database product
that created it. Container builds are generally stored in an S3 compatible
store, such as AWS S3. Customers therefore always have their own data
under their own control, and not locked into the platform.
End-of-contract process
In the event of expiration of a Subscription License or any termination of
the Agreement, Customer must remove and destroy all copies of Software,
including all backup copies, from the server, virtual machine, and all
computers and terminals on which Software (including copies) is installed
or used and confirm the destruction of the Software. All support services
cease. If the customer has created applications and services they are free
to move or migrate these applications to other instances of VMware Tanzu
or other platforms. The costs associated with doing this are borne by the
user. VMware Tanzu Labs can provide consulting services to assist in this
process. The costs associated with are dependent on the number, density
and complexity of the applications.

Availability and resilience

Guaranteed availability
Tanzu is configurable in a variety of ways to meet scalability and availability
requirements as necessary. Our Platform services teams can also advise on
the best way to set up our software to maintain high levels of availability.
Approach to resilience
Tanzu can place deployed applications across different availability zones to
ensure resilience and actively monitors and manages applications and
services to ensure a specified number of instances are available at any one
time. Tanzu can be configured to auto-scale application instances up and
down depending upon the workload on each application at the time, saving
departments money. Documentation describing how we enable resiliency is
available on request. This includes the information relating to the resilience
of the Tanzu platform and applications installed within it.
Outage reporting
There is a "live view" dashboard that allows the current state of an
application and supporting metrics to be viewed and reviewed visually.
Tanzu actively monitors applications, services, and its own components.
Alerts can also be configured if required.

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
Every VMware Tanzu software upgrade is pre-tested against our own security pipeline and alongside other components in the platform before it is shipped to customers via the VMware Tanzu Network. We perform additional vulnerability scanning of our software and dependencies using third party scanning software. Every code change to a component is linked to a requirement and has tests written for it before it is accepted into the next release. This provides tracking of every change back to the specific user need that it was required for, alongside the output of the tests
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
Regular testing is done against all our software. In addition, when a CVE is disclosed in the third party component or dependency, we take the latest fix and test it and ship it as soon as possible after the upstream project releases a fix. We also routinely harden software components to minimise the attack surface.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Service and application component logs are aggregated into a log stream allowing analysis of activity within an installation. How quickly a response occurs depends on the customer's own incident management processes and policies

Fighting climate change

Fighting climate change

Phoenix is Carbon Neutral - eight years ahead of government targets. We have achieved this by offsetting our operational emissions with carbon credit-approved schemes. By 2026 we will have further reduced our emissions by 50%, and by 2040 we will be Carbon Net-Zero.

We are ISO 14001 certified and hold IEMA membership. In addition, we have developed a Sustainability Carbon Accounting System, which is updated monthly and work closely with suppliers to ensure compliance and best practice throughout our supply chain and operations.

Contract waste will be minimised by recycling wherever possible, removing any general waste we create, and most crucially using cloud technology:

Our clean air low carbon initiatives reduce the impact of our car emissions on the environment and support people's health:

• All company cars are electric vehicles
• Car Share programmes
• Flexible working hours for public transport timetables
• Electric vehicle charging points in the car park for all employees to use on personal or company vehicles
• Use of public transport centrally arranged and promoted for customer visits as the preferred choice of travel
• Hybrid working environment with staff only required to travel to the office 2-3 times a week.
• No 'car idling' policy

To support customers on G-Cloud in fighting climate change, we will deliver the following sustainability workshops free of charge:

• Explore how Microsoft technology can help you record, report, and reduce your carbon emissions in one platform
• Understand how to procure ICT kit for a circular economy, accounting and mitigating for the carbon cost of your hardware
• Discover how you can implement ISO 14001 principles for robust environmental governance and compliance
• Learn how to engage your workforce and change their behaviours to work in greener ways, reducing paper and mileage

We ensure that our team are supported, remain in communication with management and each other, and understand that they can speak openly to their managers about their health and wellbeing to encourage discussion about how we can help them. Our programme of activities is run by our internal mental health and wellbeing ambassadors to help promote positive mental health and embed it into the culture of the organisation.

We hold internal monthly calls where employees are invited to openly discuss mental health and wellbeing, covering topics such as: loneliness, body image, Pride month, menopause support, and parental wellbeing. The aim of these sessions is to remove the stigma often associated with mental health by providing a platform that encourages open and honest conversations about mental wellbeing.

Each employee at Phoenix is given one hour a month on a Wednesday, to do something that supports their wellbeing.That’s 3,732 hours across the entire company each year dedicated to wellbeing.

We have undertaken research and engaged in internal conversations about menopause in the workplace to understand how we can better support our employees with the physical and emotional symptoms of the menopause.

We use the Microsoft Viva platform to help our employees manage their digital well-being and understand how they can change how they work to improve well-being across the organisation.

We have eight mental health first aiders across the business who are professionally trained to provide mental health support and guidance to members of our team who require it.
