TAILIEUCHUNG - Grid Computing Infrastructure

Service Oriented Architecture is an Application Architecture that is designed to achieve loose coupling among interacting software applications. SOA provides greater flexibility in developing, integrating, and managing Enterprise research, rooted in distributed and high performance computing, started in midto- late 1990s when scientists around the world acknowledged the need to establish an infrastructure to support their collaborative research on compute and data. | Grid Computing Infrastructure Nguyen Quang Huy Senior Technical Sales Consultant Agenda y Business Challenges y Solution - How Can Oracle Help? y Benefits y Market Momentum & Proof Points y Summary Agenda y Business Challenges y Solution - How Can Oracle Help? y Benefits y Market Momentum & Proof Points y Summary The Four Fundamental Goals of . y Better Information y Better Processes y Better Quality of Service y Lower Cost Balancing The Goals Is Complex Quality of Service Business Business Processes Information Cost Problem: Islands of Computation y Expensive, underutilized components y Limited reliability y Fragmented management y Slow to adjust to business needs Sales HR Files Procurement Service Supply Financials Chain Problem: Monolithic Applications y Hard to adapt to Print Invoices changing business Create requirements Generate POs Customers y Duplication of functionality means Credit Credit Verification 1 Verification 2 wasted resources y Small fixes require large User User Authentication 1 Authentication 2 investments of time and labor Account Account Validation 1 Validation 2 Inflexible, Inefficient, Hard to Maintain Problem: Complex Infrastructure Application Screen Scrape Download Application Message File Application Queue Screen Application Scrape Sockets Screen Transaction Transaction Scrape File File Application Sockets Download CICS Gateway RPC File ORB Costly, Inflexible andAPPC Incompatible Application Message ORB Application Application Message Transaction Queue Application File Message Queue CICS Gateway Transaction Screen File Scrape APPC Application Message Download RPC File Which Is Very Expensive To Manage Source: Gartner 2004 79% of Budget Spent on Maintaining Existing Systems Information Technology Evolution Grid Computing Blade Servers Low Cost SAN, NAS Internet Grid-Enabled DBMS Computing Service Oriented Arch.
