Application integration principles

States integration platform

The States integration platform plans to:

mediate between the systems and applications, transforming data from one format to another,
route data to the correct system
provide security assurance, auditing and governance functions.

These application integration principles are for:

They provide guidance on application integration in line with the Integration Platform to ensure interoperability between applications.

the definition and implementation of integrated solutions will adopt the Service Orientated Architecture (SOA) principles and technologies
services deployments should be lightweight and easily manageable
core functionality in all systems should be exposed through services and accessed through a single common integration platform
avoid deriving integration solutions from first principles. Instead all solutions will follow the design patterns in the definitive reference publication Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf
open standards and methodologies should be adopted in preference to proprietary solutions for integration
mediation between systems (consumers and provider endpoints) should be provided in line with the Enterprise Service Bus (ESB) design pattern
data entering the ESB should be normalised to a consistent for
quality of Service (QoS) aspect should be managed using centralised tools provided by the integration platform
service providers and consumers will use standard web service Application Programming Interfaces (APIs) to expose and obtain information from other services and follow the full API management lifecycle
when dealing with distributed systems integration should design interactions to be asynchronous to manage problems such as availability and latency
