Why Single Cloud Is a Risk

The decision to consolidate all IT services on a single cloud provider may seem attractive at first glance: unified administration, one contract, one invoice. But this simplification harbors significant strategic risks that companies often only recognize when it is too late.

The Single-Cloud Problem

When a company fully relies on a single cloud provider, a critical dependency is created. Technical outages, price increases, changes to terms of service, or regulatory restrictions can endanger the entire business.

Well-known incidents such as the AWS us-east-1 outage in 2021 or the Azure Active Directory outage in 2023 have shown: even the largest providers are not immune to failures. If your entire infrastructure depends on them, you face a complete operational standstill.

The Risks at a Glance

Technical dependency: A single point of failure can paralyze the entire company. No redundancy means no fallback.

Price dependency: Cloud providers can adjust prices. With complete dependency, you have no negotiating power and few options to switch.

Compliance risks: Regulatory requirements may exclude certain providers or regions. With single cloud, your options are limited.

Vendor lock-in: Proprietary services and interfaces make switching providers significantly harder later.

The Multi-Cloud Strategy as the Answer

A well-thought-out multi-cloud strategy distributes risk and creates flexibility:

• Critical workloads: are distributed redundantly across multiple providers
• Best-of-breed:: Different providers are used for their respective strengths (AWS for storage, Azure for Active Directory, GCP for machine learning)
• Geographic distribution: fulfills data protection and compliance requirements
• Negotiating power: through real alternatives

Conclusion

Single cloud may seem simpler in the short term. In the long run, a well-thought-out multi-cloud strategy is the more resilient and economically smarter decision. We help you find the right balance – without unnecessary complexity.
