Plugging Consistency Into Legacy Multi-Cloud Architecture

The most common objection we hear from prospective clients is: "This sounds great, but we cannot rip out and replace our existing tooling." We agree — and we built Synciro specifically so that you do not have to.

Our integration model is based on lightweight adapters that sit alongside existing systems and participate in the Synciro coordination protocol without modifying the systems themselves. There are three primary patterns.

Pattern one: state tapping. For infrastructure managed through Terraform or Pulumi, we deploy a Synciro adapter that watches state file changes, extracts resource metadata, and feeds it into the synchronization engine. The existing IaC workflow is unaware of Synciro's presence; it continues to plan and apply exactly as before. This pattern is ideal for read-heavy use cases like cross-cloud resource inventory and compliance monitoring.

Pattern two: Kubernetes operator. For workloads running on Kubernetes, we deploy a Synciro operator that watches Custom Resource changes, enriches them with consistency metadata, and ensures that corresponding resources across clouds are synchronized. This pattern is well-suited for multi-cluster deployment and configuration distribution.

Pattern three: webhook reconciliation. For CI/CD pipelines and secret managers, we deploy webhook listeners that capture change events and feed them into the synchronization engine. This pattern requires no code changes whatsoever and is our fastest path to integration — most teams are live within two weeks.

In all three patterns, the existing systems continue to operate exactly as they did before. Synciro adds a coordination layer on top, providing the consistency guarantees that the original architecture lacked. Teams adopt one pattern at a time, prove value on a single workflow, and expand incrementally.
