Few enterprises planned their cloud estate from a blank page. Most ended up with AWS for one product, Azure for Microsoft workloads, Google Cloud for analytics and a data centre that still runs core systems. Is that multi-cloud, hybrid cloud, or both?
This guide explains multi-cloud vs hybrid cloud and how to operate them well.
Few enterprises planned their cloud estate from a blank page.
What is multi-cloud?
Multi-cloud is the use of two or more public cloud providers, for example AWS and Azure, or Azure and Google Cloud, for different workloads. Workloads may be independent, or connected across providers.
What is hybrid cloud?
Hybrid cloud combines public cloud with private infrastructure, such as an on-premises data centre or private cloud, connected so workloads and data can interact. Examples include Azure Arc, AWS Outposts and Google Distributed Cloud, or simply VPN and dedicated connections between data centres and the cloud.
Multi-cloud vs hybrid cloud: comparison
| Aspect | Multi-cloud | Hybrid cloud |
|---|---|---|
| Definition | Multiple public clouds | Public cloud plus private infrastructure |
| Common drivers | Best-of-breed services, acquisitions, avoiding concentration risk | Legacy systems, latency, data residency, regulation |
| Main challenges | Different tools, skills, billing, security models | Connectivity, consistency, legacy management |
| Cost considerations | Fragmented discounts, egress fees | Data centre costs plus cloud |
| Operations | Multiple consoles and APIs | Two very different worlds to manage |
Many enterprises are hybrid multi-cloud: several public clouds plus on-premises.
What are the benefits of multi-cloud?
- Use the best service from each provider
- Reduce dependence on one vendor
- Meet customer or regional requirements
- Integrate acquired companies without forced migration
What are the benefits of hybrid cloud?
- Keep latency-sensitive or regulated workloads on-premises
- Modernise gradually instead of all at once
- Use cloud for burst capacity, DR or analytics
- Make use of existing data centre investments
What are the operational challenges?
- Skills: each cloud and the data centre need different expertise
- Monitoring: separate tools create blind spots. See observability vs monitoring
- Security: inconsistent identity, network and policy controls
- Cost: fragmented billing and discounts. See multi-cloud cost management
- Vendor coordination: different support contracts and escalation paths
How do you operate multi-cloud and hybrid environments well?
Unified operations across multi-cloud and hybrid
Illustration in progress
- One operating model: shared incident, change and request processes across environments.
- One observability platform with vendor-neutral instrumentation such as OpenTelemetry.
- Infrastructure as code with tools like Terraform that support all providers.
- Consistent identity and security policies across clouds.
- Unified cost reporting with consistent tagging.
- Container platforms such as Kubernetes or OpenShift for portability where it adds value.
- One escalation path for incidents, regardless of where they occur.
How Crozaint approaches multi-cloud and hybrid
Crozaint provides 24/7 managed services across AWS, Azure, Google Cloud and Alibaba Cloud, with experience of Oracle Cloud and on-premises platforms. Our ITIL-based model and single escalation matrix give you one operating model across environments, under one vendor umbrella instead of many.
We use Terraform, Ansible, Kubernetes and OpenShift for consistency, Grafana-based observability for unified visibility and FinOps for unified cost control. As an AWS Select Consulting Partner, Microsoft AI Cloud Partner and Google Cloud Partner, we operate each platform natively.
Common mistakes to avoid
- Adopting multi-cloud for its own sake
- Separate operations teams and tools per cloud
- Ignoring egress costs between clouds and data centres
- Inconsistent identity and security policies
- Forcing portability where cloud-native services add more value
Conclusion
Multi-cloud and hybrid are usually realities, not choices. What you can choose is to operate them as one: one model, one view and one escalation path.
