Formal review of dependencies on provider-specific services ensures conscious decisions about portability trade-offs. Not every service needs to be completely portable, but dependencies should be explicit and justified.
Portability Testing
Regular testing of deployment to alternative providers validates portability claims and identifies drift. Automated testing can include periodic deployment to secondary providers as part of continuous integration pipelines.
Vendor Relationships
Cloud-agnostic architecture should inform procurement and contract negotiations. Service level agreements, data export requirements, and exit assistance provisions become more negotiable when alternatives exist.
