In software engineering, Performance Testing is testing that is performed to determine how fast some aspect of a system performs under a particular workload. Performance testing can serve different purposes. It can demonstrate that the system meets performance criteria. It can compare two systems to find which performs better. Or it can measure what parts of the system or workload cause the system to perform badly.
This book introduces you to application performance management (APM) solutions and how these tools can help you monitor and troubleshoot your mission-critical applications — from the
perspective of your users, as well as your systems.
Learn how Riverbed® Cascade® gives you actionable information for network analysis and optimization, application performance management, acceleration of IT consolidation projects, and security compliance.

Ce livre blanc explique pourquoi les plates-formes d’automatisation de la mise en production et du déploiement des applications deviennent toujours plus essentielles pour les départements IT dans les multinationales. Il analyse les exigences spécifiques auxquelles une plate-forme de ce type doit satisfaire afin d’être efficace et de générer un retour sur investissement important.
Cet article examine deux approches du Zero Touch Deployment : une solution basée sur les scripts et une plate-forme d’automatisation de la mise en production. Il indique comment chacune de ces approches peut résoudre les principaux défis technologiques et organisationnels face auxquels se trouvent les organisations agiles lorsqu’elles décident d’implémenter un système de déploiement automatique.
Développement et production sont sur de mauvaises voies. Le développement se concentre sur des innovations plus rapides et sur la mise en oeuvre de nouveautés. La production a quant à elle pour objectif la stabilité, le contrôle et la prévisibilité. Souvent, ces deux équipes ne dépendent pas des mêmes personnes dans l’organisation. Elles semblent évoluer sur deux voies différentes. Peu importe la vitesse à laquelle elles avancent, elles ne se rencontrent jamais. Seules, les équipes de développement et de production IT auront souvent du mal à communiquer, encore plus à collaborer, et resteront engluées dans des processus manuels. Résultat : des employés qui ne travaillent pas bien ensemble, des logiciels qui ne fonctionnent pas de manière fiable et des clients qui envisagent d’aller voir la concurrence. Vous voilà peut-être coincé dans ce que nous appelons un « noeud de dysfonctionnement.
Comment réduire les contraintes liées aux processus sans coûts supplémentaires? La solution: un logiciel qui rassemble développement et opérations. Découvrez dans notre livre blanc gratuit « Que savent les grandes entreprises du DevOps ? » comment concrétiser l’approche DevOps au sein de votre entreprise. La démarche DevOps n’est plus une simple tendance. Lors d’une récente enquête menée auprès de 1 300 professionnels IT dans le monde, la société d’études de marché Vanson Bourne a constaté que le DevOps est devenu une stratégie informatique incontournable. Partout dans le monde, les entreprises comptent désormais sur cette méthode pour améliorer leurs processus métier, avec des résultats quantifiables.
In this research report from CA Technologies and IDG, read how many IT leaders are finding help through the DevOps movement: a discipline with the mission to improve IT service delivery agility and quality.
Agile methods have become increasingly popular because they empower organizations to more quickly address emerging opportunities, to better ensure accurate fulfillment of functional requirements and to significantly enhance team productivity. Many organizations, however, are hesitant to employ agile methods for their safety-critical systems—since they have serious concerns about compromising those systems and thereby exposing themselves to completely unacceptable consequences.IBM Rational Chief Evangelist Bruce Powel Douglass explains how best practices for project management can assist organizations in experiencing all the benefits of agile development while continuing to maintain rigorous standards essential for successful delivery of safety-critical systems.
Agile methods have a reputation for being fast and adaptive and can enhance both quality and team productivity. For these reasons they are attractive to software teams in many different domains - including safety-critical systems development. But how can agile methods be adapted to meet the needs of such a challenging domain? In the fourth episode of the series, IBM Rational Chief Evangelist, Bruce Powel Douglass discusses how agile practices can be adapted to meet the evidence needs of safety-critical projects.
Learn how Laboratory Information Systems (LIS) are becoming outdated and see how they are being replaced by Information Management Systems that can provide flexible management capabilities that provide informatics solutions.
Enterprise marketers have larger sends and bigger budgets, which increases their need to A/B test new techniques, layouts, and messaging for lead generation campaigns.

In this Solution Spotlight, QA and test managers learn more about how they can be change agents to help ensure a smooth transition to Agile for their test teams, as well as tips on fitting testing into the development lifecycle.
With an estimated 1.8 million branch offices in the US, not only is critical data being dispersed across the enterprise, but also applications. Organizations have invested in monitoring tools to help assure network and application performance, but do these tools have the visibility across the network to deliver real-time insights?
A Gigamon Visibility Fabric™ solution can extend visibility wherever critical data may exist. It eliminates the need to facilitate resources for troubleshooting and the need to install monitoring tools at every remote site. By doing so, it simplifies IT operations and centralizes monitoring tools that can reduce OPEX and CAPEX.
With critical data and applications dispersed across the enterprise, IT teams struggle to manage, analyze, and secure their networks. Even within a single location this can be a daunting task. Organizations have invested in monitoring tools to assure network and application performance, as well as security, but do these tools have the visibility across the network to deliver real-time insights?
A Gigamon Visibility Fabric™ solution can extend visibility wherever critical data may exist to address issues like oversubscription, tool proliferation, and TAP/SPAN port contention. By centralizing monitoring and simplifying IT, organizations are better able to manage, analyze, and secure the networks.
New application performance management systems can deliver rapid time-to-value and ROI for IBM WebSphere implementations by reducing the amount of time isolating problems and repairing them throughout the entire WebSphere stack.
