Good performance testing is really important, but so many companies are doing it really badly. There is a false belief that the quality of performance testing can be best improved by introducing advanced techniques and practices, but most companies are struggling to get the basics right first. Is your team making any of the top 7 mistakes? Learn what you can do to avoid them, and how you can help your company improve the quality of their performance testing. This presentation was delivered in November 2017 at the first Neotys Performance Advisory Council, held at Borthwick Castle in Scotland.

Performance Testing Strategy for Cloud-Based System using Open Source Testing...MIMOS Berhad/Open University Malaysia/Universiti Teknologi Malaysia

This document outlines a performance testing strategy for a cloud-based system using an open source testing tool. It describes introducing virtual users gradually from 1 to 3000 to test response times. Response times remained under 5 seconds for up to 1500 users but slowed for 3000 users. Testing showed faster response for high-speed internet and unloaded servers. The strategy successfully tested the system's ability to handle increasing loads in the cloud. Future work could include hosting the testing tool in the cloud and expanding performance analysis.

Cloud based Performance TestingImpetus Technologies

The document discusses harnessing the power of cloud-based performance testing. It outlines the benefits of cloud such as infinite computing power, cost savings, and ability to simulate multiple geographies. It also discusses challenges of cloud-based testing such as data security, network latency, and test management. The document provides a real-world example of a client that used a hybrid cloud solution from Impetus to conduct affordable performance testing. It concludes with recommendations such as considering cloud for uncertain goals or globally distributed users.

Cloud-based performance testingabhinavm

1. The document discusses using cloud computing for performance testing by provisioning virtual machines and load generation servers in the cloud instead of on-premise servers. 2. Commercial testing products and open-source frameworks like JMeter can be used for cloud-based performance testing, with benefits including lower costs, ability to simulate large-scale loads, and geographic distribution. 3. A case study describes a custom Hailstorm framework built on JMeter that was able to simulate 40,000 concurrent users for a client, providing rapid and cost-effective performance metrics at scale.

DevOps in an Embedded WorldSajeewa Dayaratne

All Change how the economics of Cloud will make you think differently about JavaSteve Poole

This document discusses how the economics of cloud computing will change how Java applications are developed. Cloud providers charge for computing resources on an hourly basis (e.g. $ per GB per hour), which means applications need to use resources efficiently. Java applications generally use more memory and have longer startup times than other languages. To be cost effective in the cloud, Java applications will need to reduce their memory footprint, decrease startup times, and be designed to fail and recover gracefully. The rise of APIs and microservices also requires changes to make Java more modular and efficient in constrained environments.

Principles Of Chaos Engineering - Chaos Engineering HamburgNils Meder

This document discusses chaos engineering and its principles. It provides an agenda for a talk on AWS basics, the evolution of chaos testing, tooling for chaos engineering, and chaos engineering itself. It describes how chaos engineering experiments are used to test systems by simulating failures like instance or availability zone outages. The key principles of chaos engineering are to understand normal system behavior, build hypotheses around steady states, vary real-world events by conducting experiments in production, and automate experiments continuously. Popular tools for chaos engineering include Chaos Monkey, Chaos Gorilla, and Chaos Kong.

Performance Testing webinarAbhinav Das

The document discusses performance testing and how harnessing the cloud can help address challenges. It defines performance testing and outlines the typical process. Conducting performance tests on-premises can be challenging due to lab setup and maintenance, scaling users, and testing from different locations. These challenges can be overcome by using cloud-based performance testing services which provide flexible, scalable resources and pay-as-you-go models. Visual Studio Online is highlighted as one such cloud-based solution.

From Apollo 13 to Google SRESanjeev Sharma

The complexity of managing and delivering the high level of reliability expected of web-based, cloud hosted systems today, and the expectation of Continuous Delivery of new features has led to the evolution of a totally new field of Service Reliability Engineering catered for such systems. Google, who has been a pioneer in this field, calls it Site Reliability Engineering (SRE). While it would be more aptly named Service Reliability Engineering, the name has caught on. The seminal work documenting Google approach and practices is in the book by Google by the same name (commonly referred to as the ‘SRE book’), and has become the defacto standard on how to adopt SRE in an organization. This session will cover adopting SRE as a practice in organizations also adopting DevOps; address the challenges to adopting SRE faced by large traditional enterprises, and how to overcome them.

Linux Collaboration Summit Keynote: Transformation: It Takes a Platformcornelia davis

- A cloud-native application platform can enable organizations to transform by providing speed to market, better customer experiences, and engaging their workforce. - Key elements of such a platform include continuous delivery, immutable infrastructure, blue/green deployments, self-service provisioning, environment parity, and a self-healing elastic runtime. - A cloud-native microservices architecture can provide benefits like independent scaling of services, independent development cycles, experimentation, and resilience. Managing microservices requires services for configuration, service registration, circuit breaking, and monitoring.

Anand Ahire - Electric Cloud - Visibility, Coordination, Control. Getting st...DevOps Enterprise Summit

On the road to Continuous Delivery and/or DevOps? Just want to deliver better software faster? Pipelines are a key to achieving these goals because going fast and still producing quality output requires better visibility, coordination, and control. There is confusion out there on how best to use pipelines, and where they should be used. I’ll separate the ideal from the reality so you can figure out your next steps. During this talk we will demonstrate how ElectricFlow can provide visibility to all stakeholders, coordinate multiple people and automations, and control what gets released into production environments.

Sam Fell - Electric Cloud - Faster Continuous Integration with ElectricAccele...DevOps Enterprise Summit

This document discusses how ElectricAccelerator can dramatically accelerate software builds and tests by automatically parallelizing jobs across shared CPU clusters.

ElectricAccelerator Huddle provides a free option for small teams.

Maintaining SLOs of Cloud-native Applications via Self-Adaptive Resource SharingVladimir Podolskiy

This document presents an approach for maintaining service level objectives (SLOs) of cloud-native applications via self-adaptive resource sharing. The approach involves collecting performance data under varying resource limits and workloads, removing anomalies from the data, learning prediction models to map service level indicators to resource limits and workloads, and optimizing resource allocation to meet SLOs under changing conditions. The approach is evaluated using three applications deployed on Kubernetes and aims to augment Kubernetes' vertical pod autoscaler.

Webinar: Automating the Creation and Use of Virtual Testing Environments Skytap Cloud

Skytap provides on-demand cloud environments to help enterprises deliver better software faster by removing inefficiencies in the product development lifecycle. Traditional on-premise environments cause delays, restrict parallel development, and lead to defects due to inconsistent environments. Skytap's self-service cloud environments eliminate these problems by providing on-demand, pre-configured environments that developers can access immediately, reducing the time spent on environment management and reproducing defects.

How NBCUniversal Adopted DevOpsSanjeev Sharma

NBCUniversal is implementing DevOps practices like continuous integration, delivery, and testing using tools from IBM like UrbanCode Deploy, IBM Dev-Test Environment as a Service (IDTES), and IBM Cloud Orchestrator. This allows them to continuously test code, deploy applications across hybrid clouds, and improve collaboration between development and operations teams. NBCUniversal's DevOps practices aim to address issues like slow release processes and lack of integration between development stages.

From Monolith to Microservices – and Beyond!Jules Pierre-Louis

Software application development and delivery often involves multiple development, infrastructure and operations teams, each with their own preferred “tools of the trade” for building, testing and deploying code changes For years, virtualization and cloud technologies have provided agile, on-demand infrastructure. The advent of Microservices promises even more agility– but what is required to take advantage of Microservices? Join Electric Cloud CTO Anders Wallgren and Trace3 Principal Consultant - DevOps Marc Hornbeek as they discuss what is required to: - Overcome culture and architecture challenges created when decomposing monolithic applications into Microservices-based applications. - Coordinate integration, testing, monitoring, packaging, release approval and deployment of Microservices-based applications over elastic infrastructures - Create a controlled and auditable delivery pipeline to support Microservices-based application. - Prepare for “future” applications, pipelines and patterns.

Fast Delivery DevOps IsraelAdrian Cockcroft

The document summarizes Adrian Cockcroft's experience giving talks about Netflix's approach to technology over time. It notes that initially people reacted skeptically, saying Netflix's approach was crazy and wouldn't work (2009-2010). Later, people said it could only work for large companies like Netflix (2011). By 2012, people said they wanted to adopt a similar approach but couldn't. The document outlines key lessons learned from Cockcroft's time at Netflix, including that speed wins in the marketplace and removing friction from product development helps enable faster innovation.

A True Story of Why QA Loves DevOpsIBM UrbanCode Products

Tanay Nagjee - Electric Cloud - Better Continuous Integration with Test Accel...DevOps Enterprise Summit

Stop sacrificing comprehensive testing to save time Software testers and quality assurance engineers are often pressured to cut testing time to ensure products are released on time. Usually this means running fewer tests, thus reducing software quality. This pressure is exacerbated as companies embrace a continuous integration (CI) approach which involves frequent build and test cycles, but has the side effect of further limiting the time allocated to test and analysis. Instead of reducing the number of tests in a CI cycle to reduce test time, Tanay Nagjee will discuss how entire test suites can be broken down and parallelized, reducing the time to run them by 80% or more. By leveraging a cluster of computing horsepower (either on-premise physical machines or in the cloud), large test suites can execute in a fraction of the time it takes by smartly parallelizing their individual tests. Tanay will outline a 3-step approach to achieve these results with different test frameworks. He will discuss the tools used, and will present real example data and a live demonstration.

Demystifying Operational Features for Product Owners - AgileCam - SkeltonThat...Skelton Thatcher Consulting Ltd

Treating operational aspects of software as 'non-functional requirements' and 'an Ops problem' rather than a core part of the software product leads to poor live service and unexplained errors in Production. Deployability, recoverability, diagnosability, monitorability, and high quality logging are simply features of a software system, along with user-visible features surfaced via the UI, or a capability of an API endpoint. However, many Product Managers understandably feel uneasy about taking on the (necessary) responsibility for prioritising operational features alongside user-visible and API features. This session aims to bring Scrum Masters and Product Owners up to speed on operational features, empowering them to make effective prioritisation choices about all kinds of product features, whether user-visible or operational.

To fill this gap some NoSql vendors are building SQL access to their systems. Building SQL engine from scratch is a daunting job and frameworks like Apache Calcite can help you with the heavy lifting. It allows you to integrate SQL parser, Cost-Based Optimizer, and JDBC with your NoSql system. Calcite has been used to empower many BigData platforms such as Hive, Spark, Flink, Drill, HBase/Phoenix to name some. In this session I will walk you through the process of building a SQL access layer for Apache Geode (GemFire). I will share my experience, pitfalls and technical consideration like balancing between the SQL/RDBMS semantics and the design choices and limitations of In-Memory-Data-Grid systems like Geode. Hopefully this will enable you to add SQL capabilities to your preferred NoSQL data system.

Design Optimization of Reinforced Concrete Waffle Slab Using Genetic AlgorithmJournal of Soft Computing in Civil Engineering

This research presents the optimization techniques for reinforced concrete waffle slab design because the EC2 code cannot provide an efficient and optimum design. Waffle slab is mostly used where there is necessity to avoid column interfering the spaces or for a slab with large span or as an aesthetic purpose. Design optimization has been carried out here with MATLAB, using genetic algorithm. The objective function include the overall cost of reinforcement, concrete and formwork while the variables comprise of the depth of the rib including the topping thickness, rib width, and ribs spacing. The optimization constraints are the minimum and maximum areas of steel, flexural moment capacity, shear capacity and the geometry. The optimized cost and slab dimensions are obtained through genetic algorithm in MATLAB. The optimum steel ratio is 2.2% with minimum slab dimensions. The outcomes indicate that the design of reinforced concrete waffle slabs can be effectively carried out using the optimization process of genetic algorithm.

Using the Artificial Neural Network to Predict the Axial Strength and Strain ...Journal of Soft Computing in Civil Engineering

The main purpose of the current study was to formulate an empirical expression for predicting the axial compression capacity and axial strain of concrete-filled plastic tubular specimens (CFPT) using the artificial neural network (ANN). A total of seventy-two experimental test data of CFPT and unconfined concrete were used for training, testing, and validating the ANN models. The ANN axial strength and strain predictions were compared with the experimental data and predictions from several existing strength models for fiber-reinforced polymer (FRP)-confined concrete. Five statistical indices were used to determine the performance of all models considered in the present study. The statistical evaluation showed that the ANN model was more effective and precise than the other models in predicting the compressive strength, with 2.8% AA error, and strain at peak stress, with 6.58% AA error, of concrete-filled plastic tube tested under axial compression load. Similar lower values were obtained for the NRMSE index.
