Ask HN: How are you solving internal integration?

Between microservices / lambdas / databases and streaming topics, there's a huge number of internal data sources we're stitching together.

OpenAPI etc help, but there's a discovery phase of tracking down the right sources, and building out the integration, which can be labor intensive, and repetitive as APIs gain consumers.

Worse, these tools can result in tight couplings between producer & consumer that make future changes hard.

Is this a problem that resonates at your orgs? How are you solving this issue?
