While the elastic nature of cloud computing means that resource intensive applications can go from dozens to hundreds of virtualized servers at the press of a button, this is not always the best way to manage overall computing power and performance. Moreover the use of cloud computing, unless within a performance management program, is often not as cost effective as leveraging local system resources.In this session we'll look at the new computing models of cloud computing, and how performance management issues both change, and remain the same. We'll take a deep dive into the way that computing power is offered today from both private and public clouds, how to model these environments, and how to reach both cost and computing resource efficiency."

Apdex is an open standard supported by members and sponsors of Apdex Alliance. This session, by Apdex Alliance founder, Peter Sevcik, will cover three topics. Peter will briefly descibe the Apdex methodology. He will report on Apdex adoption progress and Alliance membership growth. He will then present case studies highlighting insights gained using Apdex. The case studies will feature several Apdex deployments including using Apdex to: visually track global performance using a color-coded map; select a web hosting service; and track online retail performance. Peter will also use real-world case studies to explain how to determine the best Apdex T (threshold)."

This technique for measuring processor utilization is efficient and generally adequate for capacity planning. However, it lacks the precision performance engineers require for application optimization and tuning, particularly over small measurement intervals. The session then introduces newer techniques for measuring processor utilization in Windows that are event-driven. The event-driven approaches are distinguished by far greater accuracy, enabling the reconstruction of the precise path that threads, processes and processors take when they execute. Gathering event-driven measurements entails significantly higher overhead, but measurements indicate this overhead is well within acceptable bounds on today’s high powered server machines."

Digital Infrastructure encompasses Business Requirements, Technology Infrastructure, and Facilities Infrastructure. This session utilizes a case study from a typical financial services company to demonstrate how the private cloud architecture impacts the Digital Infrastructure: servers, PODs, power, space and the associated CAPEX and OPEX costs. The company will roll PODs into production starting in January 2012. This session shows how the POD architecture can be utilized cost effectively to prevent the need for a new data center."

New Capacity Planning methodologies that provide a panoptic model of all of the IT and business variables are the only way of delivering a ‘risk free’ increase in IT services. Companies can no longer afford to just build new datacenters, or expand existing ones. They are already probably full or filling to capacity, most likely at their maximum power consumption or cooling capacity due to the number of high density servers installed and the vast arrays of storage being required to meet both business needs and regulatory retention requirements. The problem, then, is just how do companies keep rolling out those business critical applications whilst keeping the “lights on” in the datacenters? There are always a number of unique challenges facing companies with datacenters: - Uplifting existing services which often means periods of parallel running;- Keeping test and development systems for current testing, future development and regression testing; - Bringing online new/upgraded applications and/or new and additional users; - Tech refresh where servers, operating systems, applications, communications and storage equipment becomes end-of-life and needs replacing/upgrading. All of these result in a necessity to manage the peaks and troughs in power consumption, cooling requirements and floor space/rackspace. This workshop intends to detail the methodology and toolsets we have developed to aid our clients in just this endeavor. I will run through what is involved in capacity managing a modern day datacenter, and explain how and why our roles have changed from being server/mainframe centric, to requiring a complete understanding of everything from power trains to aircon, servers to storage and networks to user activity. If you manage capacity and performance, or datacenters, storage or networks, this workshop will give you an understanding as to why you need to understand more than just one area. The session is intended to be an informative and interactive discussion of the techniques we use and how we apply those to different clients, about the challenges we have faced, how we have overcome them."

There is no simple, formal definition for a private cloud to use as a reference. There seems to be a concensus regarding the term ""Public Cloud"" or, simple ""Cloud"". Amazon is a poster child. Infrastructure is made available through the Internet through a simple, self-service portal. The user pays only for the time that is being used. There is no up-front capital investment. Public cloud elasticity allows computing consumption to grow from 1 server to 10,000 adn back to 1, while the cost is incurred on an hourly basis. So, does a private cloud work that way also? Other than elasticity and the ""pay by the drink"" cost model, what else does a cloud provide that can be realized within the Enterprise? What does it mean to mix private and public clouds to create a Hybrid Cloud model?

The cloud is often viewed as a source of new perform problems, a problem set for which there are no tools available yet. An opposing point of view is that the cloud is an enabler for performance engineering, i.e. the cloud can be leveraged to quickly and cheaply solve problems that have plagued us in the past.

The same techniques and tools can be used to model System z, Unix/Linux, and Windows. At the heart of these models is the essential queueing network. This course provides the details of the essential queueing network, including the necessary statistics that need to be collected from the system, as well as various modeling techniques that yield insights that cannot be gleaned from observing the actual computer system. Once the model is validated, it can be used to explore ""what-if"" scenarios where either the workload or the underlying configuation can be changed in the model so that the resulting service levels can be observed. If time permits, an additional section on the subject of time series estimation and forecasting will be presented. This course will not teach you everything you need, but it will give you a full survey of the various approaches witha full bibliography for future reference. PART 1: This is the first of three sessions. Computer performance modeling is mainly focused on understanding how business activity and the infrastructure can be analyzed to understand the impact on IT services.

The overhead to produce this data can impact system performance while the amount of data to manage and process this data can impact system performance while the amount of data to manage and process can require a lot of additional system resources. This is the reason why many sites collect just a small part of the DB2 metrics (or no DB2 measurements at all) in their SMF data.
