Middleware technologies conceptualized in the 1990s were designed for stable, batch-oriented applications that ran behind a firewall, communicating only via XML and SOAP. The need now is for an integration solution that can handle both real-time and batch integration needs, that has been built for cloud and mobile usage as well as on-premise, and can work with a variety of communication formats and protocols.
In the past, integrations between applications were carried out using an enterprise service bus (ESB). But it was only large enterprises, with complex internal systems, and with technical skills and budget, who could implement an ESB. What modern businesses require is a better data transfer engine, but you don’t need an ESB for that anymore.
A more agile, cost effective, and more appropriate solution for application and data integration – that any type and size of business can use – is an integration platform-as-a-service (iPaaS). An iPaaS is a cloud-based integration platform that is used to build, deploy and orchestrate integrations between applications that can run anywhere – cloud, on-premise, and mobile.
