Gartner defines the application programming interface (API) management market as the market for software that supports API life cycle stages such as planning and design, implementation and testing, deployment and operation, and versioning and retirement. Organizations use APIs to modernize their architectures; efficiently integrate systems, services and partners; and create and monetize data and services. API management software enables organizations to discover, design, build, manage and secure APIs, regardless of their size, region or industry. It helps them improve composability, security and business resilience, and accelerate their growth.
'Application integration platforms enable independently designed applications, apps and services to work together. Key capabilities of application integration technologies include: • Communication functionality that reliably moves messages/data among endpoints. • Support for fundamental web and web services standards. • Functionality that dynamically binds consumer and provider endpoints. • Message validation, mapping, transformation and enrichment. • Orchestration. • Support for multiple interaction patterns, content-based routing and typed messages.
Gartner defines integration platform as a service (iPaaS) as a vendor-managed cloud service that enables end users to implement integrations between a variety of applications, services and data sources, both internal and external to their organization.
