Evolution to SOA – Groundwork for Application Virtualisation

1. Evolution to SOA – Groundwork forApplication Virtualisation A peak on the versatility and agility of the ClearPath systems participating in the SOA maturity stack and Application Appliances Neville Bradbury OpenSoft Australia Rudi Chati Unisys Corp. WW – ESS Thursday – May 8th, 2008 10:00 am UTF1: Evolution to SOA Groundwork for Application Virtualisation

2. Topics Covered • The “Ultimate” Vision – Application Virtualisation • Growing into the SOA maturity stack • a “functional positioning” peek on the SOA layers supporting the view (hidden supporting slides) • the various layers of abstraction – SOA, BPM, governance CP Native & J2EE UTF1: Evolution to SOA Groundwork for Application Virtualisation

3. Virtualization –unbinding the computing resource Unisys RTI Virtualization is more then machine virtualization – i.e. running multiple virtual operating systems on a server. Machine virtualization is not a one-size-fits-all solution, nor is it the whole story. Virtualization is much bigger than that and has much more impact. UTF1: Evolution to SOA Groundwork for Application Virtualisation

4. Virtualisation – a stack of functional capabilities • IT administrators can provision, consolidate and manage their virtual infrastructure right alongside their physical machines • the presentation layer provisioning (user interface) of the application is abstracted • application execution and the data used are thus isolated from the user’s client operating system • abstracts hardware from the operating system • consolidation of multiple physical machines onto one server • allows for greater mobility and flexibility in provisioning and migrating workloads across the virtualised server farms. • application itself is isolated from the operating system and its dependence on system configurations • containerised” applications are not installed centrally, but are managed centrally and deployed directly in a contained, virtualised image – “appliance” UTF1: Evolution to SOA Groundwork for Application Virtualisation

5. High level of virtualisation requires - architecture & new type of business & IT services UTF1: Evolution to SOA Groundwork for Application Virtualisation

6. Bringing virtualisation – to life requires: • A cohesive virtualisation strategy across the IT infrastructure • Integrating the management of virtual and physical computers with policy-based tools to reduce system complexity • Implementing advanced security, continuity, and recovery techniques to maximise business availability • Driving the necessary culture changes for effectively managing resources in a virtual environment building a mature SOA stack – including – governance & ITIL UTF1: Evolution to SOA Groundwork for Application Virtualisation
