Description
Many organisations keep part of their systems on-premises while running others on public cloud platforms. Where these environments meet, questions about network paths, identity, data location and operational responsibility need deliberate answers. Without them, the two halves tend to evolve separately and become harder to manage over time.
This service supports the design of hybrid cloud architectures. The work starts with an inventory of existing systems, their dependencies and their regulatory or latency constraints, and then defines which workloads belong in which environment and how they communicate. The output is a reference architecture that your internal team can review, adapt and implement.
The design covers connectivity between data centres and cloud regions, identity federation, access boundaries, backup and recovery paths, monitoring across both sides, and cost visibility. Each decision is documented with its reasoning, so later changes can be assessed against the original intent rather than reconstructed from memory.
The service is advisory and design-focused. Implementation, migration execution and ongoing operations can be handled by your own staff or by a partner of your choice, and the design is written to be usable by either.
Who it is for
-
IT leadership planning a multi-environment strategy Teams that must decide how existing data centre assets and cloud platforms will coexist over the next several years.
-
Infrastructure and platform engineers Staff who will build and run the environment and need a clear reference for network, identity and workload decisions.
-
Organisations with regulated or latency-sensitive systems Businesses that must keep certain data or services on-premises while still using public cloud capacity for other workloads.
Programme
-
Discovery and inventory
Review of existing applications, infrastructure, data sets, dependencies, and compliance or latency requirements that affect where each workload can run.
-
Workload placement
Classification of systems by suitability for on-premises, public cloud, or a split deployment, with the rationale recorded for each category.
-
Connectivity and network design
Definition of network paths, addressing, routing, and secure links between environments, including redundancy and failure behaviour.
-
Identity, access and security boundaries
Design of identity federation, privileged access controls, encryption responsibilities, and segmentation between the environments.
-
Operations and handover
Specification of monitoring, backup, cost tracking, and ownership model, followed by a documented handover to your internal team.
Frequently asked questions
- Does the service include building the environment?
- The service focuses on design and documentation. Implementation can be carried out by your own team or by a partner you select, and the design is prepared so that either can use it.
- Which platforms does the design cover?
- The design is shaped around your existing infrastructure and the public cloud platforms you use or are considering. Platform-specific details are agreed during the discovery stage.
- Can the design be reviewed after it is delivered?
- Yes. The documentation records the reasoning behind each decision, which makes it possible to review and adjust the architecture as requirements change.
- How is data location handled?
- Data placement is assessed against your regulatory, contractual and latency requirements. Where rules are unclear, the design records the open question so it can be resolved with the relevant advisers.
