Platform-as-a-Service and API-First Architecture

Software as a Service has evolved beyond simple cloud applications into comprehensive platform ecosystems. Companies like Salesforce, Shopify, and Stripe have transformed from SaaS providers into platform companies that enable thousands of developers to build and distribute applications.

The future of SaaS lies in composable architectures where businesses can assemble best-of-breed solutions through APIs and integrations. This shift toward modularity and interoperability is enabling more specialized, focused software solutions that work together seamlessly.
