IBM Software Group Outline Performance and Reliability are important The Grid is an important component of business computing, today, and for the future On Demand – the drive for ultimate flexibility and integration Leads us to Grid The Grid in business Typical Examples of commercial Grid applications A different kind of example Trends, Consequences, Questions for Performability
IBM Software Group Performance, Reliability are important Reliability, Quality A growing part of software development budget is spent on performance, test and service Problem rates on new technologies (e.g., J2EE) are high and climbing New solutions are required.
IBM Software Group An on demand business is an enterprise whose business processesintegrated end-to-end across the company and with key partners, suppliers and customerscan respond with speed to any customer demand, market opportunity or external threat. On Demand Business – The Why
IBM Software Group Present Reality: Functional Automation Limitations of Tight Vertical Integration: Monolithic applications cant be reused economically, efficiently Ad hoc integration creates connections that are difficult to change/maintain Lack of standards limits ability to deliver meaningful interoperability Marketing Partners Web Partners Sales Partners
IBM Software Group Marketing Partners Web Partners Sales Partners What Business needs: Horizontal Process Integration Advances that make it possible: Standards for creating services and enabling them to communicate are agreed upon by major vendors Infrastructure that supports self-defined, loosely coupled services has emerged Tools to incorporate existing assets are available Automation and virtualization of systems resources readily available Need to Integrate
IBM Software Group Marketing Partners Web Partners Sales Partners What Business needs: Horizontal Process Integration Need to Integrate Business Flexibility IT Simplification Increased focus on business flexibility Relentless use of open standards to enable communication and integration across the value net Partner to sharpen focus and respond to opportunities and threats Requires an on demand IT environment Ability to repurpose application functionality in order to support horizontal processes Automation and virtualization of resources

IBM Software Group Performability in an on demand world Performance Reliability
IBM Software Group Flexibility and Responsiveness drive On Demand Flexibility Componentisation Reuse Simplification Virtualisation at all levels of Resources Autonomic control Reliability (predictability) Finer modularity Security Responsiveness Open Stds Performance And they, in turn, drive Virtualisation (Grid) And also have consequences for Performability
IBM Software Group Trends, their Consequences, and Questions Security A classic antithesis for performance A critical and growing requirement for business But a growing problem we all face, e.g., Viruses 6.5M in 2003 Antivirus scans - 3 hours of downtime Overhead for J2EE security managers --------------------------------- This will continue to grow 6M Viruses so far in 2004
IBM Software Group Performance Reliability Security - Typically drives performance down - pathlength goes up - scalability is constrained -Typically enhances reliability -Availability also goes down with virus scans, etc. Security Open, Grid environments scale up security issues, and mandate more attention. Do we need to model these interactions explicitly? Are present techniques adequate? Appropriate? e.g., to capture viral spreading patterns, containment Trends, their Consequences, and Questions
IBM Software Group Trends, their Consequences, and Questions Scalability Whatever we think is large and complex now, wont be in the future. We see this in some of the grid examples we are familiar with Games motivates another jump in scale 10,000 users at a time Communities of 500,000s of users Wireless gaming will drive server demand, and strain adaptive capabilities even harder Security issues will multiply profoundly Gaming is real commerce People buy virtual things – e.g., castles, etc., on ebay!
IBM Software Group Trends, their Consequences, and Questions Complexity A growing concern for software in general New technologies/disciplines – e.g., componentisation, Aspect Oriented Software Development - must help, but for now, we are faced with: One factor that contributes to growing security overhead Also to resulting models of reliability and overall fragility
IBM Software Group Trends, their Consequences, and Questions Componentisation and Reuse Demands modularity and reuse in models Demands incremental, scalable, composable models Autonomic Systems What is a failure in a self-healing system? What are the reliability characteristics of a system that is adaptive? How is this to be characterised, measured, modelled?

IBM Software Group Trends, their Consequences, and Questions Autonomic Systems What is a failure in a self-healing system? What are the reliability characteristics of a system that is adaptive? How is this to be characterised, measured, modelled?
IBM Software Group Trends, their Consequences, and Questions Business focus is needed Growing Recognition of the importance to IT of Business Events, Business Processes For deeply technical people this is a hard concept But, technology exists to solve business problems There are some interesting opportunities for performability as well. E.g., Reliability as a factor in service level objectives, agreements Dynamic, operational performability Measuring and Characterising Business Performance; Business Reliability. The Reliability of Services. Business Performance Management monitors and visualizes the behaviour of business processes by correlating IT events and business activities, thus enabling performance optimization according to business goals
IBM Software Group Summary Performance, Reliability are growing business concerns The Grid solves real business problems and is part of the overall solution in delivering increasing flexibility and responsiveness. Dependency on Software is growing in all levels of IT solutions Complexity is growing Security is a growing requirement, and the tradeoffs between security and performance need to be better understood The IT focus is moving increasingly higher up the software stack; indeed, beyond the software into the business domain. Reliability, Performance and Availability are more complex with dynamic provisioning and autonomic control
