Today, many organisations do not work with a single cloud provider. One application may run on Microsoft Azure, an analytics workload on Google Cloud, a backup solution on AWS and critical systems on a local cloud platform. This gives flexibility, but if it is not managed it leads to fragmentation in identity, cost and security. In this guide we explain what multi-cloud management is, the common problems it brings and how to build a sustainable operating model.
What is multi-cloud and why choose it?
Multi-cloud means an organisation using services from more than one cloud provider at the same time. The difference from hybrid cloud is this: hybrid cloud refers to private infrastructure and public cloud working together, while multi-cloud refers to using more than one cloud provider. Both models exist side by side in most organisations. For more on hybrid cloud, see our hybrid cloud article.
Organisations usually move to multi-cloud for these reasons:
- Different workloads running better with different providers
- The wish to reduce dependency on a single provider
- Inheriting several cloud environments through mergers and acquisitions
- Data location and regulatory requirements
Common problems
- Identity sprawl: Separate user and role definitions in each cloud make access tracking difficult.
- Network complexity: Connectivity between environments, addressing and traffic costs require planning.
- Cost visibility: Different billing models make it hard to see total spend at a glance.
- Policy inconsistency: Applying the same security rule differently in each environment creates audit gaps.
- Skills burden: Each provider has its own tools and terminology; team knowledge is easily split.
A sustainable operating model
Success in multi-cloud depends more on shared standards than on tools:
- Central identity management: A single identity provider is federated to each cloud; roles are standardised on the principle of least privilege.
- Tagging standard: The owner, environment and cost centre of every resource are specified with mandatory tags.
- Central monitoring and logging: Metrics and logs from all environments are collected in a shared view.
- Policy as code: Security and configuration rules are applied the same way to every environment through templates.
- Regular cost reviews: Idle resources and right-sizing opportunities are reported periodically.
Managed multi-cloud operations: what can be handed over?
When the day-to-day operation of a multi-cloud environment is handed over to a managed service provider, the scope can typically include subscription and account management, monitoring and alerting, patch and backup operations, security configuration reviews and cost reporting. Authority over architectural decisions and business priorities usually stays with the organisation.
It is important to separate two concepts here: continuous monitoring of the environments and how quickly, and with what scope, an incident is responded to are different commitments. Response scope varies according to the chosen service tier and should be defined separately in the contract.

Frequently Asked Questions
When does a multi-cloud strategy make sense?
It makes sense when different workloads run better with different providers, when you want to reduce dependency on a single provider, or when several cloud environments have come together through mergers and acquisitions. Because it increases operational complexity, it should not be chosen without a clear rationale and ownership model.
How is identity and access management organised across multiple clouds?
A central identity provider is usually used and federated to each cloud. Role definitions are standardised on the principle of least privilege, and privileged access is logged separately. This provides authorisation and an audit trail from a single point.
How is cost visibility achieved in a multi-cloud environment?
A tagging standard, an account and subscription hierarchy and a central reporting layer should be put in place. Mandatory tags are defined to show the owner, environment and cost centre of each resource. Regular usage reviews reveal idle resources and right-sizing opportunities.
What does running a multi-cloud environment as a managed service cover?
The scope is defined by the contract. It typically includes subscription and policy management, monitoring and alerting, patch and backup operations, security configuration reviews and cost reporting. Which resources are included in operations should be stated clearly in the responsibility matrix.
How are security policies kept consistent across different clouds?
Policies are defined as code and applied to every environment with the same template. Configuration scanning tools, central log collection and a shared incident management process are used. In this way, deviations are detected and corrected to the same standard without depending on each provider's different interface.
Should we run multi-cloud management with our own team or through a managed service?
The decision depends on your team's cloud expertise, on-call capacity and the number of environments. For small teams, continuous monitoring and the operational workload can be heavy; in that case, sharing responsibility with a managed service makes sense. In a mixed model, decision-making authority stays with you while day-to-day operations are supported externally.
