Load & Performance TESTING

Oct 26, 20101 like1,943 views

The document discusses load and performance testing for software. It recommends dividing testing into components and testing individual components to find root causes of issues. It suggests using tools like Grinder and HTTP Quality Assurance Toolkit (HTTP-QAT) which are open source and allow testing various systems with Java clients like ActiveMQ, LDAP, and JDBC. HTTP-QAT builds on Grinder and allows standardized testing using the HTTP protocol with configurable files. It can run statistically distributed load testing scenarios or be used for monitoring with Nagios.

QA&test 2016 (Bilbao) Pros and Cons of Doing Performance Testing Along with D...Federico Toledo

��You better start testing at the beginning,�� is what everyone in testing says these days as new methodologies such as agile and test driven development are becoming increasingly popular. What is the best way to go when it comes to performance testing? Should we start it right away (taking a lean approach) or at the end (following a more waterfall style approach)? The speaker, Federico Toledo, will compare two different real world performance testing projects that he took part in over the past 10 years. The first project employed a more waterfall like approach, meaning, the whole load testing project took place at the end of development. In the second one, development and load testing projects started on the same day (planned by two different teams but as part of the same team) in a more lean approach. He will go into detail about the pros and cons of each project. After the presentation, you will end up coming to your own conclusions about which one is right for you. Additionally, Federico will reveal insights about monitoring and problem solving in production, mistakes to avoid in each, and the skills one should develop to be a successful performance tester. http://www.qatest.org/es/programme/speaker_info.php?id_speaker=247&day=1

Load Balancing with ApacheBradley Holt

This is a presentation made at the Burlington, Vermont PHP Users Group about configuring load balancing using the Apache HTTP Server. Load balancing is a technique that can distribute work across multiple server nodes��here we will discuss load balancing HTTP (i.e. web) traffic. There are many software and hardware load balancing options available including HAProxy, Varnish, Pound, Perlbal, Squid, nginx, and Linux-HA (High-Availability Linux) on Linux Standard Base (LSB). However, many web developers are already familiar with Apache as a web server and it is relatively easy to also configure Apache as a load balancer. Related concepts such as shared nothing architecture are discussed. We also take a look at some basic load balancing scenarios and features including sticky sessions and proxying requests based on HTTP method. Distributed load testing with Tsung is briefly discussed as well.

This document discusses optimizing a Magento application before scaling it. It provides tips for optimizing server settings like Linux kernel settings in sysctl.conf to increase limits. It also recommends optimizing Nginx, PHP-FPM, Redis, and MySQL settings. For PHP-FPM, it suggests tuning the process manager and using TCP. For Redis, it advises using three instances each with its own database and port. For MySQL, it recommends turning off query caching and tuning InnoDB settings. The goal is to optimize application performance and flow before scaling to a clustered architecture.

Developers Driving DevOps at Scale: 5 Keys to SuccessDevOps.com

As DevOps adoption matures in organizations, DevOps teams are leading the charge for enabling enterprises to scale their DevOps efforts to support increasingly complex application delivery requirements. Tooling and processes that might have worked for more simple use cases often fail when applied across large-scale software delivery -- needing to support ALL teams, GEOs, point-tools, applications, processes, regulatory requirements, environments, and more. How do you improve developer productivity and release velocity, without sacrificing governance, security, and org efficiency? How do you streamline your processes and organizational alignment, without sacrificing flexibility and freedom of choice? How do you support thousands of developers, applications and pipelines - both legacy and cloud-native - without getting buried in plugins/tools/spaghetti-scripts hell? Join guest speaker Charles Betz, lead DevOps analyst at Forrester Research, and Loreli Cadapan, Sr. Director Product Management at JFrog, as they share architectural patterns, best practices and proven tips for scaling DevOps in the enterprise.

Tech Talk: Don't Forget Operations in Your Continuous Delivery PracticeCA Technologies

The document discusses the importance of including operations in continuous delivery practices. It emphasizes that continuous delivery should focus on the entire service delivery model, including the needs of operations such as high availability, incident management, and role-based access control. It also recommends expanding automation to include more than just code deployment, such as database configuration, security tools, and monitoring probes. Finally, it stresses understanding the overall application operating model.

Orchestrate Continuous Delivery with Jenkins and DockerNicolas De Loof

le "Continuous Delivery" est un sacr�� buzz word, et "Docker" encore plus, mais les blog que j'ai pu lire sur sujet ne proposent qu'un pipelines naif et minimaliste : compile, test, push docker image, et voil��. En 2015 Jenkins adresse clairement plus que de l'Integration Continue, et avec le support r��cent du workflow plugin nous pouvons orchestrer avec un DSL des pipelines de grande complexit��. L'integration avec Docker lui donne encore plus de puissance. Pendant cette session, je vais construire un pipeline de CD from scratch pour montrer l'utilisation du workflow et sa flexibilit��, ainsi que le support de Docker.

Continuous Deployment for Staging and Production EnvironmentsOlyaSurits

Continuous Deployment allows teams to get immediate feedback, debug, iterate, and fail fast, ultimately getting a better product into the hands of users faster. In this talk, Kendra and Celia will talk about the challenges and benefits of continuously deploying their staging environments and how they applied that to their production environment during the development of CockroachCloud. They will discuss their use of: Iterative development including PR structure and feature decomposition Pushing all PR to staging environment Feature Flags to make the customer magic happen

DevOps NoteHirokazu MORIKAWA

This document discusses the concept of DevOps from multiple perspectives. It provides definitions and viewpoints on DevOps from several experts in the field. Key points made include that DevOps is a cultural and professional movement focused on collaboration between development and operations teams. It is not about any single tool or technology, but rather the collaborative culture and processes that arise from that culture. DevOps aims to break down silos between dev and ops.

Monitoring the behavior of a system is essential to ensuring its long-term effectiveness. However, managing an end-to-end observability stack can feel like stepping into quicksand, without a clear plan you��re risking sinking deeper into system complexities. In this talk, we��ll explore how combining two worlds��developer platforms and observability��can help tackle the feeling of being off the beaten cloud native path. We��ll discuss how to build paved paths, ensuring that adopting new developer tooling feels as seamless as possible. Further, we��ll show how to avoid getting lost in the sea of telemetry data generated by our systems. Implementing the right strategies and centralizing data on a platform ensures both developers and SREs stay on top of things. Practical examples are used to map out creating your very own Internal Developer Platform (IDP) with observability integrated from day 1.
