  2. The Day-to-day Challenges Infra & Appl Consolidation Re-engineering & Migration Reduce TCO; Improve Profitability Agile, high-assurance Systems Capacity Planning; Resource Scheduling Security & Compliance Anomaly Detection; Root-cause Analysis Operational Excellence IT Plant Management: Tasks

  3. The Problem Infrastructure Inventory 4000+ business apps Average age: 3.5+ years 10-20 years: 190+ 20+ years: 60+ Significant overlaps 25+ account opening apps 10+ authentication apps 12+ credit decision engines 15+ BI tools, … 30,000+ servers 5+ OS w/ 20+ versions 10+ database products 2500+ app server instances 25+ middleware envr. 35+ programming languages 200,000+ desktops 10+ petabytes of storage 197,000 e-mail boxes, … Main Challenge: Scale & Complexity Top-tier bank in the US

  4. The Problem Main Challenge: Scale & Complexity

  5. The Problem Plant Mgmt Compliance Operation Support Application Dev Teams Security Capacity Planning The Problem is Further Compounded … Too many different views and silo-based understanding; Little understanding of the global picture !

  6. Understanding the Problem Where Has Complexity Come From? • Key contributor: Evolution • Evolution dimensions: • Technology: Hardware, software (OS, middleware), tools, … • Functionality: Application and system, business • Requirements: Service levels • Workload: Types and volume • Business: New markets, Globalization, M&A, … • State-of-the-art: “Reactive Fire-fighting” • System evolution is manual and intuition-based … an art form ! • Focus is on “quick fix” rather than “right fix” • Implications: • High total-cost-of-operations (TCO) • Brittle IT plants  Reluctance to upgrade anything • Deployment time >> Development time  Lack of agility Lack of design principles for system evolution  Complexity Educational problem: Students don’t understand systems engineering or evolution
