You're running production on one cloud, then a compliance requirement pushes a workload to a second provider. Now you're managing two sets of APIs, two billing dashboards, and two completely different operational models. That's multicloud, and most organizations are already there. The hard part isn't adopting multicloud. It's operating it well, because interoperability across providers is genuinely difficult. This guide covers what multicloud infrastructure is, how it differs from other cloud models, its main benefits and challenges, where Redis fits, and what trends matter most.
What is multicloud?
Multicloud is a cloud strategy that uses services from at least two public cloud providers to run apps and workloads. You adopt it to match each workload to the provider that best fits its needs, whether that means geographic coverage, AI services, pricing, or compliance support.
The term gets confused with hybrid cloud, but the difference is straightforward. A multicloud approach combines multiple public clouds. Hybrid cloud combines private infrastructure, usually on-premises or private cloud, with one or more public clouds and coordinates workloads between them. In practice, many enterprise environments are both.
How multicloud infrastructure works
Multicloud infrastructure is the layer that ties multiple public clouds together into something your team can actually operate. It can also connect to private or on-premises systems, but the defining feature is distributing apps, data services, or environments across more than one public cloud.
In practice, that means deciding how you deploy code, how data replicates between environments, and how you keep latency predictable for users in different regions. Multicloud is as much an operating model as a technical one. Picking the clouds is the easy part; the hard part is the operational discipline to run them together.
Benefits of multicloud infrastructure
Multicloud doesn't deliver benefits by default. Each advantage below depends on deliberate design choices, not just running in more places.
Flexibility & provider fit
Running on multiple clouds helps you place apps where they fit best. One provider may offer stronger regional presence, another may be better for AI workloads, and another may line up better with industry-specific compliance needs.
Cloud platforms aren't interchangeable. A multicloud approach gives you room to choose based on workload requirements instead of forcing every app into one provider's strengths and weaknesses.
Availability & disaster recovery
Distributing apps across clouds can improve resilience when downtime isn't an option. Replicating data across providers and regions can reduce user latency and limit the blast radius of a single provider issue.
That benefit depends entirely on design. Cross-cloud availability comes down to how data is replicated, how failover is handled, and whether your apps can keep operating when one environment degrades.
Cost & negotiating position
Working with multiple providers can give you more negotiating room and more freedom to rebalance workloads over time. It doesn't lower spend by default.
More providers means more contracts, more billing systems, and more chances for waste if you're not actively tracking usage. The real advantage is optionality when pricing, service quality, or technical requirements change.
Multicloud challenges
The flip side of those benefits is operational complexity. The biggest challenges are governance overhead, provider-specific dependencies that still make apps hard to move, and the compounding effect of managing separate systems, policies, and integrations for each cloud.
Increased operational complexity
Every cloud has its own APIs, dashboards, security model, and support processes, and those differences add up fast. Without strong internal platform engineering, running across providers can slow delivery as teams spend more time handling infrastructure differences than building features.
This is one reason many organizations struggle to get the results they expected. Running in multiple clouds is easy to describe and harder to standardize.
Governance & compliance
Each provider logs activity differently and exposes different policy controls, which makes governance harder across the board. Security teams need unified rules for identity, access, auditability, and data handling across all environments.
Compliance adds another layer of pressure. Legal requirements don't change just because workloads move between clouds, so you need a governance model that works across all of them.
Vendor lock-in by another route
Spreading services across providers reduces dependence on any single one, but lock-in still shows up in different forms. A workload that depends heavily on proprietary services can still be expensive and disruptive to move later.
That's why mature teams pair their multi-provider strategy with FinOps discipline. FinOps brings financial accountability to cloud spending through collaboration between engineering, finance, and operations teams. They track where workloads run, why they run there, and which provider-specific choices are worth the trade-off.
Multicloud trends shaping 2025–2026
Those operational challenges haven't slowed adoption, but they've changed what teams focus on. The main trends shaping 2025–2026 are AI workload placement, sovereign cloud requirements, and Kubernetes standardization. Together, they show how multicloud is moving from a sourcing decision into a broader platform strategy.
AI is a big driver because providers differ in GPU access, managed AI services, and regional availability. If you're building inference pipelines or retrieval-augmented generation (RAG) apps, where your data lives and how fast you can retrieve it matters as much as which model you're calling. At the same time, data residency and sovereignty rules are pushing organizations to keep some workloads in specific jurisdictions while still using global cloud infrastructure.
Kubernetes also matters because it gives you a standardized way to package and run apps regardless of which cloud they land on. It won't eliminate the complexity of operating in multiple environments, but it can reduce how much app deployment logic has to change from one to another.
Keeping data fast & consistent across clouds
One of the harder problems in any multi-provider setup is keeping your database layer fast and consistent across clouds and regions. Your compute can move between providers, but if every request still routes back to a single-region database, you've just added latency to every user outside that region. This is where Redis fits.
Redis Cloud is fully managed and integrated with AWS, Google Cloud, and Azure, so it works as a portable database across providers without tying your architecture to a single one. Your apps get sub-millisecond latency from an in-memory architecture regardless of which cloud they're running on, and you don't have to manage separate caching, session, or data infrastructure for each provider.
For teams that need cross-region writes, Active-Active Geo Distribution uses conflict-free replicated data types (CRDTs) to automatically resolve conflicting writes across regions and clouds, with 99.999% availability on Active-Active deployments. Apps read and write to a local instance, and replication happens behind the scenes. That means your database can span multiple providers without requiring custom sync logic or giving up sub-millisecond local latency.
This also matters for AI apps in a multi-provider environment. If you're using vector search or semantic caching as part of a RAG pipeline, Redis keeps your vector embeddings, cached responses, and operational data in one platform rather than splitting them across provider-specific services. That's one less integration to maintain per cloud, and one less vendor-specific dependency to manage when you need to shift workloads.
Redis Software offers a self-managed option for on-premises and private cloud environments, giving teams full control over data locality and compliance while using the same platform they run in the cloud. The same Redis Query Engine, the same data structures, and the same client libraries work across both deployment models.
Multicloud works when your data layer is portable
Multicloud infrastructure works best when you choose it for clear operational reasons and standardize how you run it early. The strongest strategies map workloads to providers intentionally, set governance rules up front, and keep data infrastructure as portable as practical.
Redis gives you one fast, portable data layer across AWS, Google Cloud, and Azure. Your data access patterns don't change when your infrastructure does. Whether you need caching, vector search, session management, or real-time messaging, it works the same way on every provider.

Frequently asked questions
What is the difference between multicloud & hybrid cloud infrastructure?
Multicloud distributes workloads across services from more than one cloud provider. Hybrid cloud bridges different infrastructure types, connecting on-premises or private cloud with public cloud resources to balance control and scalability. The key distinction is infrastructure mix: multicloud spans multiple providers, while hybrid combines different infrastructure types. Many organizations run both models simultaneously.
What are the biggest challenges of managing workloads across multiple clouds?
Operational fragmentation and governance are the biggest issues. Teams must learn different monitoring tools, alerting systems, security models, and troubleshooting workflows for each provider, which slows incident response. Cost visibility suffers because billing data arrives in different formats, making it hard to compare true costs without third-party tools. Network connectivity between clouds adds latency and egress fees, and data synchronization grows complex when apps need consistent state across providers.
How does Kubernetes help with multicloud deployments?
Kubernetes abstracts many cloud-specific differences through a unified container orchestration layer. You can write deployment logic once and reuse the same tools and workflows across providers. It also simplifies secrets management and supports consistent continuous integration and continuous deployment (CI/CD) pipelines across clouds. Kubernetes won't eliminate multicloud complexity (you still handle differences in cluster configuration, storage, identity and access management (IAM), and managed services), but it reduces the friction of moving containerized apps between providers.
How can you reduce vendor lock-in in a multicloud strategy?
Prioritize workload portability through containerization, cross-provider infrastructure-as-code templates, and abstraction layers that minimize direct API dependencies. Using open standards and Cloud Native Computing Foundation (CNCF) certified tools creates more migration pathways than relying on proprietary managed services. Treat portability as an ongoing architectural decision, not a one-time choice.
What multicloud trends matter for 2025 & 2026?
Expect more platform engineering teams to emerge as dedicated functions that build internal developer platforms and abstract away cloud differences. Multicloud networking is maturing with better cross-cloud connectivity, including private backbone links and improved software-defined wide area network (SD-WAN) solutions. Edge computing is also pushing multicloud strategies beyond centralized regions. Watch for rising data egress fees to drive more architectural decisions as moving large datasets between providers gets expensive at scale.
