Abstract:
A defining characteristic of the information age is our reliance on vast, complex, and intertwined information technology (IT) plants - consisting of large numbers of heterogeneous, high-capacity computing, communication, and storage systems as well as wide-range of software components. The rapid increase in the complexity of such IT plants, however, is fast approaching a barrier. The presence of this barrier is evident in: (1) the nearly universal reluctance of system administrators to modify existing functional systems, even when upgrades are required; (2) the widespread recognition that IT systems are brittle and respond to changes in unpredictable ways; and (3) the fact that IT plants have become very labor intensive and costly to maintain, with system administration and upgrade accounting for 60 - 80% of the TCO in many IT plants. Consequently, systems that we depend on to promote change are fast becoming obstacles to change. We argue that continuous evolution is a key contributor to complexity. Evolution of IT plants is governed by several factors, including the need to accommodate additional software functionality or users; as well as the need to meet the demands of changing requirements, changing technology and/or changing operating conditions (workload, faults, etc.). Today, evolving IT plants in a timely manner while maintaining desired levels of performance, stability and security is an art - system evolution tasks are intuition-based and manual. The inherent complexity of hardware and software components when coupled with continuous evolution of plants often lead to scenarios where technicians understand components, but can neither predict nor control the IT plant. The objective of the Systems Research Lab (SRL), a new R&D entity being established at TRDDC, is to conquer complexity by developing methodologies and tools to manage system evolution. As a first step, we have defined the Data-intensive Computing initiative to understand and model operational characteristics of IT plants, and thereby simplify many tasks such as capacity planning, faculty detection and isolation, anomaly detection, and performance engineering. To achieve this goal, we are developing a unified, extensible, and customizable architecture - referred to as the Information Integration and Inference (I3) architecture - for monitoring, assimilating, and analyzing large volumes of data from a diverse set of distributed and heterogeneous sources. In this talk, I will describe the overall R&D vision for the Systems Research Lab, and then outline some of the specific activities and challenges involved in the Data - intensive Computing initiative.
