Developers need to integrate the multiple SaaS systems that businesses use to operate across disparate clouds. The most important aspects of integration are accurately mapping business data between systems and ensuring reliability, availability and consistency. Developers also need to allow decentralized access to integrated SaaS solutions. An integration platform can abstract integration concerns and manage them, while an API-led approach builds reusable APIs that represent systems and processes without disrupting business. A good connectivity platform provides templates and connectors to make integrations easy and fast.
