Is migrating from AWS to a Multi-Cloud strategy worth the increased architectural complexity?

All answers to this question.

Multi-Cloud is a double-edged sword. While it theoretically provides better resilience, it often introduces "lowest common denominator" syndrome, where you can't use platform-specific features like AWS Lambda or Azure Functions to their full potential because you need the code to be portable. To make it work, you need a robust abstraction layer like Terraform for Infrastructure as Code and Kubernetes for container orchestration. In my experience, most mid-sized firms find that a "Primary Cloud" with a "Secondary Cloud" for specific niche services (like GCP for data analytics) is more manageable than a true 50/50 split.

Have you considered if your current application architecture is truly cloud-native, or are you just planning to "lift and shift" your virtual machines across different providers?

• Charles, we are currently in a hybrid state. Most of our legacy apps are lift-and-shift, but our newer microservices are running on EKS. My concern is that if we move to a Multi-Cloud setup, we’ll spend all our time debugging inter-cloud networking latency rather than improving the apps. I’m starting to think that staying with a single provider but utilizing multiple availability zones and regions might give us the 99.99% uptime we need without the massive headache of managing three different consoles.

The hidden cost of Multi-Cloud is egress fees. Moving data between AWS and Azure can get incredibly expensive if you don't design your data flow very carefully from the start.

• Martha is spot on. Egress fees are the "silent killer" of cloud budgets. You really need a dedicated interconnect like Direct Connect or ExpressRoute to make it viable.
