How your very large databases can work in the cloud computing world? Presented by Moshe Kaplan from RockeTier, a performance expert and scale out architect at the IGT Cloud Computing work group at April 20, 2009 Cloud computing is famous for its flexibility, dynamic nature and ability to infinite growth. However, infinite growth means very large databases with billions of records in it. This leads us to a paradox: "How can weak servers support very large databases which usually require several CPUs and dedicated hardware?" The Internet industry proved it can be done. These days many of the Internet giants, processing billions of events every day, are based on cloud computing architecture such and sharding. What is Sharding ? What kinds of Sharding can you implement? What are the best practices? RockeTier specializes in analyzing and boosting existing software performance and developing efficient high-load systems You can contact Mr. Kaplan at moshe.kaplan at rocketier.com, read his blog at http://top-performance.blogspot.com and visit RockeTier site at www.rocketier.com

28. Startup your Engines Thank you [email_address] http://top-performance.blogspot.com Our Methodology Performance problems are extremely complex and due to the diferent technologies deployed, each case is unique. A “typical” performance problem requires delving into databases, application servers, client technology, code in difering programming languages and system and software architectures. RockeTier implements a unique methodology in order to simplify the problem and evaluate each performance bottleneck, providing both an immediate efective relief and when necessary, design a gradual roadmap to speed up your software system and make it scalable and robust. Our 5 steps methodology : 1. Detect: Pinpoint your performance bottlenecks using various tools including load and stress tools, code profiling, database profiling, network sniffing and code review to detect performance bottlenecks in specific components. 2. Rate: Grade each bottleneck by importance and provide immediate practical recommendations and performance boost estimations. 3. Immediate effective relief: Provide immediate fixes and workarounds in a short time frame helping you meet your urgent business needs. 4. Roadmap Planning: When necessary, redesign next generation Solutions, using proven robust and scalable solutions such as grid and in memory databases. 5. Scale up and Scale out: In cases where redesign is necessary - RockeTier provides implementation or software design description (SDD), and guidance for in house programmers for the implementation of the next generation scalable system, which will meet your growing business needs. Your Value Business: Achieve your business performance requirements. GreenIT: Protect the environment and reduce CO2 emissions. Bottom Line: Reducing hardware and 3rd party software cost. The Performance Experts Success Stories The Finance Sector: An international insurance company managing over 20 Billion US dollars in assets was facing poor performance in its core life insurance policy software system. The RockeTier team detected bottlenecks originating from several software infrastructure modules. A practical solution was implemented. The customer’s success criteria was a 20% decrease in insurance policy creation run time, Our solution provided a 40% decrease in run time! Telecom: A VC backed start-up company was facing critical installation problems in the leading Israeli cellular operator. Knowing that existing system performance would not meet client requirements, the company asked RockeTier to help it boost its performance. RockeTier evaluated the system and implemented a workaround to the system database architecture, boosting the overall system performance by 30%. Following that. the RockeTier team designed the company’s next generation architecture, meeting a throughput of 3000Mbps by design. RockeTier at a Glance RockeTier is a software solutions company, which utilizes its knowledge and skills to help companies from both the enterprise sector and the start-up industry. RockeTier has numerous success stories in solving customers’ system performance bottlenecks and scale out limitations, providing immediate improvements and workarounds in a short time frame and, when necessary, redesign and implementation of the next generation solutions employing grid and/or in- memory databases in the Web 2.0, Telecom and finance markets. Web 2.0: a start-up company providing an innovative electronic advertising and billing system was facing its technological limits. The RockeTier team evaluated and redesigned its system architecture and is currently implementing a scale out grid mechanism and caching algorithms. The solution supports 20 times the original capacity using the same hardware. Moreover it supports semi-linear growth (by simple scale out) and high availability requirements. “ 20% reduction in transaction time within 3 months” “ Boost Performance by a factor of 200” “ 200 million events per day”
