How Do You Become Truly Multi-Cloud?

A Technical Perspective on Portability, Control, and the Road to Decentralization

"Going multi-cloud" used to mean running workloads across AWS and Azure, maybe sprinkling in GCP for redundancy. Today, that’s table stakes.

As infrastructure complexity grows, so do the definitions—and expectations—around multi-cloud strategies. For developers, architects, and platform teams, the real goal isn’t just using multiple clouds. It’s gaining freedom from cloud lock-in—in data, compute, orchestration, and ultimately, control.

But achieving true multi-cloud? That requires rethinking the cloud-native stack itself.

The Illusion of Multi-Cloud

At face value, multi-cloud means distributing applications or services across more than one cloud provider. This may include:

• Hosting primary workloads in AWS and backup in Azure
• Using GCP’s AI/ML stack while storing assets in Amazon S3
• Leveraging Kubernetes clusters across different regions or providers

But here's the catch: multi-cloud deployments still rely on centralized, siloed infrastructure. You’re still tightly coupled to vendor-specific services like IAM, networking layers, APIs, storage configurations, and pricing models.

This leads to:

• Data gravity – moving large volumes between clouds is costly and slow
• Hidden egress fees – extracting data often incurs higher costs than storing it
• Operational inconsistency – varied tooling, logging, and observability stacks
• Limited portability – vendor-locked formats and APIs reduce agility

So how do you go from multi-cloud in name to multi-cloud in practice?

Pillars of a True Multi-Cloud Architecture

To move beyond superficial redundancy, a technical multi-cloud strategy must address:

1. Data Portability

You need to store and access data in formats and locations that aren't tied to a single vendor. This includes:

• Using object storage protocols (like S3) across providers
• Avoiding proprietary file systems and closed platforms
• Ensuring you can read, write, and verify data from any location or tool

2. Infrastructure Abstraction

Deployments should be cloud-agnostic. This means:

• Using container orchestration (Kubernetes, Nomad)
• Infrastructure-as-code (Terraform, Pulumi) with provider-neutral modules
• Avoiding services with no cross-provider equivalent (e.g. DynamoDB, BigQuery)
  
  

3. Automated Failover and Federation

• Use DNS-based routing, edge CDNs, and anycast IPs to balance and route requests
• Keep service states synced, or decouple using event-driven architectures
• Replicate workloads and data at the network edge to ensure resilience
  
  

4. Security and Identity

Your security model must span providers without losing coherence:

• Centralized secrets management
• OIDC or federated identity providers
• External policy enforcement (OPA, Kyverno)

The closer you get to neutral interfaces, portable data, and modular security, the more cloud freedom you gain.

But Here's the Limiting Factor: Storage

Data is the heaviest, most persistent part of your infrastructure stack. And it’s the piece least suited to traditional multi-cloud tactics.

Storing redundant copies across multiple clouds:

• Is expensive
• Incurs unpredictable egress and access fees
• Introduces synchronization complexity
• Doesn’t eliminate vendor risk—only duplicates it

That’s where decentralized storage changes the equation.

Decentralized Storage: Multi-Cloud Without the Middlemen

Instead of replicating your data across cloud silos, decentralized storage replicates it across independent, globally distributed nodes—outside the control of any single provider.

Here's how it supports true multi-cloud strategies:

• Protocol-level portability: Store data once and access it from anywhere via content-addressed IDs (CIDs) or S3-compatible gateways.
• Verifiable availability: Storage providers prove cryptographically that your data exists and is unchanged—removing the need to trust centralized logs or dashboards.
• No vendor lock-in: You can switch compute providers, migrate applications, or even change your orchestration layer without moving your storage.
• Low-to-No egress fees: With networks like Filecoin and IPFS, retrieving your own data doesn’t incur arbitrary costs.
• Built-in redundancy: Data is replicated across regions and nodes automatically, not just across zones in a single cloud.
  
  

The Filecoin Perspective: Abstracting the Storage Layer

At Filecoin DeStor, we believe multi-cloud ends at decentralized storage.

Instead of architecting around the constraints of AWS, Azure, or GCP, we start with storage that is:

• Globally addressable
• Provable
• Immutable or versioned
• S3-compatible, but not cloud-bound
  

Our APIs and white-glove solutions allow developers and enterprises to integrate decentralized storage directly into their stack—whether they're building across clouds, on bare metal, or at the edge.

Multi-cloud used to be a matter of survival. Now, it’s a strategy for resilience, sovereignty, and speed. And decentralized storage is the foundation that makes it real.
