🌐 Multi-Cloud Strategy: Freedom of Choice for Every Service

When your business lives in a single cloud, you're not a client—you're a hostage. According to the Parallels 2026 State of Cloud Computing Survey, 94% of organizations are concerned about vendor lock-in, and 93% of enterprise companies already operate in multi-cloud environments. Let's explore why and how.

⚠️ The Problem with a Single Cloud:

🔒 Vendor lock-in — switching providers costs months of work and millions of rubles.
​
📉 Limited flexibility — you are forced to use one provider's tools, even when a competitor offers a better and cheaper solution.

💰 Price lock-in — 81% of companies cite cost optimization as the main driver for moving to multi-cloud, but only 25% believe they are getting full ROI from their cloud investments.

✅ Solution: Multi-Cloud Approach

The essence is simple — each service lives in the cloud where it performs best:

☁️ Yandex Cloud → ML in Russia, services subject to various compliance requirements.

☁️ AWS → ML/AI environments
​
☁️ Google Cloud → Analytics and BigData (BigQuery + Vertex AI)
​
☁️ Azure → For Windows-oriented infrastructures (native integration with Active Directory, Office 365, Power BI)
​
☁️ Local clouds → For hypersensitive data

🛠 Tools to Help You Work with Multi-Cloud

☝️ Crossplane — manage resources across all clouds via Kubernetes API. Uses YAML and continuous reconciliation: if someone manually changes a resource, Crossplane automatically restores it to the desired state. Ideal for teams deeply embedded in K8s.
​
☝️ Terraform — Infrastructure as Code using HCL. Supports 3000+ providers, from AWS to custom on-prem solutions. The gold standard for IaC, especially if you need broad coverage.

☝️ kubectl — manage multiple K8s clusters via contexts. One command kubectl config use-context production-west switches between clusters in different clouds.

Crossplane and Terraform work great together. Terraform for initial infrastructure provisioning, Crossplane for Kubernetes-native lifecycle management.

🚀 How to Start Your Move to Multi-Cloud?

1. Audit your services.

Divide your services into categories: compute, bigdata, ML/AI, infrastructure-heavy services, compliance-bound services, etc. Determine which provider is best suited for each.

2. Start with a "second arm"

Don't migrate everything — add one provider for the category identified in step one, or for a new project. This ensures the safest separation. Try to choose a category with the least vendor lock-in.
​
3. Implement IaC

Terraform or Crossplane — it doesn't matter, the key is: no manual resource creation. Infrastructure as Code equals portability.
​
4. Unified visibility.

Set up centralized monitoring and logging across all clouds. Without a single pane of glass, multi-cloud turns into chaos.
​
5. FinOps practices

Implement FinOps to control costs across all providers. Without this, multi-cloud will cost more than a single cloud.
​
6. Zero Trust Security

Don't forget security. Implement Zero Trust Security for all cloud services.
