Program
Users are more and more demanding when it comes to application performance and this is reflected in very restrictive SLA contracts. It is therefore crucial to integrate performance management in computing projects as early as possible and not only for the development teams but also for the teams in charge of infrastructure and hosting. This seminar will show you how to implement an efficient management of your performance.
Exercise
Demonstrations. Discussions on various cases.
PROGRAM
The basics of IT performance
- The four pillars of performance : availability, robustness, response time, scalability.
- From availability management to high availability : law of 9, MTBF, MTTR.
- How to evaluate the availability of an application ?
- Contracting process of services levels (SLA).
- What about Java, .NET and PHP platforms ?
- Comparison of levels of performance with «old platforms » : mainframe, AS 400.
- Are Open-Source solutions compatible with high levels of performance ?
- What are the main problems one comes across on new IT architectures ?
Include performance in project management
- From a curative management of performance to a preventive approach.
- When to make prototypes ? On which parameters ?
- Carry out technical tests in the development phase : methods and tools.
- estimate the costs of integration phases and the cost of transitions to the production phase.
- The role of ITIL in the production process.
- Applications designed for production. Facilitate configuration of applications.
- Improve communication between applications and the production teams' tools
- Architectural and development best practices : The impact of Java and .Net virtual machines on performances.
- The new programming constraints.
- Patterns and good coding practices
- Profiling tools.
Hardware infrastructures and performances
- Servers and processors : The impact of multi-heart CPUs ; The new mainframes (Unix and Windows)
- Storage : The impact of RAID technologies on performance ; What are SAN and NAS approaches ? ; Distributed file systems (GFS, GPFS...) ;
- Networks : Virtual IP addresses ; Solutions for load-distribution on networks.
- Data-Centers : Choice of location. Power supply, ventilation, wiring. WAN links.
- Server virtualisation : Operating principles ; Solutions : VMWare, Virtual Server , XEN ; Virtualisation and performance : what impact ?
Software infrastructure and performances
- Clustering, principles of « load balancing » and « session fail-over ».
- Active/Passive type clusters. Active /Active type clusters. Hybrid clusters.

Monitoring and supervision
- Monitoring : Life cycle of a monitoring solution ; Key documents to produce and maintain ; Information gathering on availability and performance. Different sources of information; The 5 types of monitoring.
- Application supervision : Defining indicators and their different states ; Defining thresholds, rules and alarms ; Composite indicators ; Reporting (scoreboards).
- SNMP standard : Principles, MIB and basic orders ; SNMP support in Java 5 and Windows
- JMX standard : Principles ; JVM monitoring with MXBeans ; Mbeans specific development ; Overview of available tools around JMX
