WHERE ARE WE NOW?


Need to move from pilot programs to production, BUT:

• Effort from prototype to commercial product is uncertain

• Complexity, need for flexibility, computing demands increasing

• Industry awash in a mix of tech concepts

• Greater need for standards

• Safety and security remain a priority

What’s needed:

• New design approaches to make tech scale & fit timelines & budget

Services Oriented Architecture Benefits

▪ Decoupling – Application can be built, altered and scaled

▪ Componentization – Services as independent components can be easily replaced and upgraded

▪ Autonomy – Developers and teams can work independently

▪ Continuous Delivery – Allows frequent releases of software through systematic automation of creation, testing and approval of software
