And as you'll read below, an emerging class of middleware leverages container technology to help developers connect to resources distributed across multiple clouds. Portal middleware, for example, encompasses the application front-end as well as tools for back-end connectivity database middleware typically includes its own data store. Middleware got its name because the first middleware typically acted as a mediator between an application front-end, or client, and a back-end resource - e.g., a database, mainframe application or specialized hardware device - from which the client might request data.īut today's middleware operates well beyond this scope. (There's even middleware that lets developers build their own customized middleware.) Still others, such as a cloud-based integration platform as a service (iPaaS) offering or an enterprise service bus (EBS), function as a centralized integration hub for connecting all the components in an enterprise. Others, such as web application servers or mobile device middleware, provide the full range of communication and connectivity capabilities needed to build a particular type of application. Some, such as message brokers or transaction processing monitors, focus on one type of communication. By making it easier to connect applications that weren't designed to connect with one another - and providing functionality to connect them in intelligent ways - middleware streamlines application development and speeds time to market. Middleware is software that enables one or more kinds of communication or connectivity between two or more applications or application components in a distributed network. Middleware speeds development of distributed applications by simplifying connectivity between applications, application components and back-end data sources.
