Cloud agnostic means designing software and systems so they can run on any cloud platform, like AWS, Azure, or Google Cloud Platform, without relying on features from only one provider. It helps teams avoid vendor lock-in and move workloads easily.
Tools for cloud agnostic include:
- Containerization: Use Docker so applications run consistently everywhere.
- Orchestration: Use Kubernetes, which is supported by all major cloud providers.
- Open-source databases: Use PostgreSQL or MySQL instead of cloud-specific databases when portability is important.
- Infrastructure as Code (IaC): Use tools like Terraform to provision infrastructure across multiple clouds.
- Standard APIs and protocols: Avoid relying heavily on proprietary cloud services.
Trade-offs
Cloud agnostic apps come with costs over cloud native apps :
- Giving up some advanced cloud-native features.
- More engineering effort to maintain portability.
- Potentially higher operational complexity.
- Sometimes lower performance than using provider-specific managed services.
