Middleware and iPaaS: integration trends for distributed architectures

The evolution of enterprise middlewareTraditional middleware is gradually giving way to cloud integration platforms (iPaaS). In 2026, the iPaaS market exceeds 10 billion dollars, driven by the proliferation of SaaS applications and the need to interconnect heterogeneous ecosystems.The market leadersMuleSoft (Salesforce), Boomi (formerly Dell), Workato and Microsoft Azure Integration Services dominate the market. Each platform offers prebuilt connectors to the most popular applications, along with low-code tools for custom integrations.Key trends for 2026Event-driven integration is gaining ground over traditional batch approaches. API composition makes it possible to build composite services from existing APIs. AI embedded in iPaaS platforms automatically suggests data mappings and detects integration anomalies.Practical adviceStart by mapping your existing integration flows. Evaluate iPaaS solutions on the breadth of native connectors, ease of monitoring and the pricing model. Favor platforms that offer a hybrid mode (cloud + on-premise).Source: Forrester Research, “The State of Enterprise Integration 2026”, March 2026
