Hybrid hosting across cloud and retained infrastructure
Some applications need to span cloud and retained infrastructure. We help plan where their parts run and how those parts connect, so the combined service works for the people using it.
Hybrid hosting concerns placement and delivery. For ongoing operational care after deployment, see hybrid management.

Map the application before moving a part of it
User access, processing, data and integrations may already sit on different systems. Moving one component changes the paths between them and can affect delay, throughput or availability. The best location for one part is not always the best arrangement for the whole application.
We review those dependencies alongside support requirements, licensing and data movement. Some components may need to stay together. Those decisions should come from the application’s needs rather than a general preference for cloud or on-site hosting.
Design for both normal operation and a failed link
Connections need enough capacity and appropriate access controls. Routing, name resolution and sign-in dependencies all belong in the plan. Basic connectivity does not establish that every required task will work.
Then consider a failure: which functions remain available, which stop and what must recover first? Those questions make the design assessable. They also expose situations where a cloud component still relies on a local service that has not been included in continuity planning.

Be clear about what each organisation supplies
The proposal identifies Proxar-supplied resources, retained customer systems and services provided by others. Ownership and delivery responsibilities should remain visible when the work reaches implementation.
Several teams may need to provide access, change configurations and test results. Agree the sequence so a successful change in one environment does not unexpectedly interrupt another. Keep outstanding dependencies assigned to the people able to resolve them.
Accept the combined result, not separate green lights
Test sign-in, data access and integrations along the paths users depend on. Recovery planning needs to account for the order in which connected components return, not just whether each can restart on its own.
The documentation should help the operating team make future changes without rediscovering the design. For the business reasons behind a mixed approach, see hybrid cloud. Where workloads are moving, cloud migration services covers the delivery process and handover.

Before you decide
Your questions, answered
Does every part have to be supplied by Proxar?
No single ownership model is assumed. We establish which systems remain yours, which resources are supplied and which other providers are involved. The combined arrangement must be supportable within the agreed work, with access and responsibilities clear across all of those parts.
Can we move only one part of an application?
That needs a dependency review. Moving processing, data or an integration can change network behaviour and support requirements. Check the application supplier’s conditions and test the important paths before assuming a component can be moved independently without affecting the rest.
What happens if the connection between environments fails?
The design should describe which tasks continue, which become unavailable and the recovery order. Test the agreed scenarios rather than assume that hosting in two places creates automatic resilience. Shared identity, data or connectivity dependencies can still affect the whole service.
Who manages the environment after it is built?
Ongoing administration needs its own agreement and handover. Hybrid hosting covers placement and delivery; your team or an agreed provider then needs the records, access and responsibilities to operate it. We can discuss hybrid management alongside the project without treating it as an automatic inclusion.
