The engineers are concerned aboutportability. Vendor-specific APIs and tools create a dependency on a single provider, leading to vendor lock-in. This limits the ability to migrate services or workloads to another provider without significant rework.

Reliability and availability refer to service uptime and continuity, while scalability addresses performance under demand. Although important, none of these directly relate to cross-platform flexibility. Portability ensures that services, data, and applications can be easily moved or integrated across environments.

By adopting portable solutions—such as open standards, containerization, and multi-cloud strategies—organizations reduce long-term risks, increase negotiation power with providers, and enhance resilience.
