This agreement also complements Microsoft’s broader AI investments and partnerships. The company has consistently emphasized that its future growth depends on enabling others to build and scale AI applications on its cloud. Large, long-term contracts like this one help secure predictable revenue while strengthening Azure’s position against rivals.
Strategic Implications for Amazon Web Services
Before this Microsoft deal, Perplexity was widely understood to rely heavily on Amazon Web Services (AWS) for its cloud needs. AWS remains the world’s largest cloud provider and continues to dominate many enterprise and startup workloads.
However, the Perplexity Microsoft AI cloud deal suggests that AI startups are becoming increasingly cautious about over-reliance on a single cloud provider. In the AI era, compute availability, pricing, and contractual flexibility can have outsized impacts on a company’s ability to innovate and compete.
By committing substantial spending to Microsoft while reportedly maintaining AWS as a major partner, Perplexity appears to be hedging its bets. This approach could allow the company to negotiate better terms, access diverse tools, and avoid disruptions caused by capacity constraints or policy changes at any single provider.
For AWS, the deal serves as a reminder that leadership in cloud infrastructure is no longer guaranteed, especially as AI workloads place
unprecedented strain on global data center capacity.

Why Multi-Cloud Is Becoming the Default for AI Companies
One of the most important takeaways from this deal is the growing normalization of multi-cloud architectures in AI development. Unlike traditional software applications, AI systems are exceptionally resource-intensive and sensitive to performance variations.
By spreading workloads across Zmultiple cloud providers, AI companies can:
- Reduce the risk of outages or service disruptions
- Optimize costs by choosing the most efficient platform for specific tasks
- Access specialized hardware or services unique to each provider
- Maintain strategic independence in negotiations
The Perplexity Microsoft AI cloud deal fits squarely into this trend. Rather than locking itself into a single ecosystem, Perplexity appears to be building a more flexible infrastructure strategy that can adapt as its products and user base evolve.
