Multi-cloud strategies are becoming increasingly popular in cloud environments. They offer advantages like data distribution, high availability, and avoiding vendor lock-in without relying on a single provider. However, they also come with challenges such as management complexity, cost tracking, and maintaining consistent security policies. What are your experiences with this? What issues do you most commonly face in multi-cloud teams, and what approaches have you adopted to overcome them? Also, is a single-cloud approach or a hybrid model more sustainable in the long run? I’d love to hear your thoughts and recommendations!

In our latest project with a company developing an IoT home application, we adopted a multi-cloud strategy to avoid vendor lock-in. We deployed databases on AWS RDS, used Azure Functions for real-time event processing, and allocated Google Cloud Storage for storing video files from cameras. The increase in availability and the ability to choose the best tool for each component was evident, but we faced significant challenges in unifying security policies and cost monitoring across different platforms. To address this, we implemented a centralized monitoring tool (Datadog) and connected all clouds to a unified Identity and Access Management (IAM) interface using SAML, enabling us to create and update unified policies with a single click.
From my experience, combining multi-cloud and hybrid models provides the best balance between flexibility and cost. When high performance or specialized services are needed, we can switch to the most suitable cloud, while keeping part of the infrastructure on-premises for sensitive data or regulatory requirements. The key is having an abstraction layer for resource management and policy unification; otherwise, the difference between benefit and burden becomes a significant overhead.
