Explainer

Point-to-point legacy integration relies on custom-coded connections between every system, creating a tightly coupled architecture that struggles to scale. Modern alternatives like API-led connectivity replace this model with reusable, loosely coupled APIs that improve agility, reduce maintenance, and lower long-term costs.

Core information
  • Legacy integration builds custom code to connect each system directly to every other system, resulting in a complex web of dependencies.
More details and nuances
  • The accumulated point-to-point code creates a tangled mess that becomes progressively harder to maintain, directly increasing technical debt and ongoing costs.
