It is good to see more books on the performance testing/engineering genre recently. One of my favorite books is The Art of Application Performance Testing series by Ian Molyneaux. On this line, James Pulley's book is different, it is completely a non-technical book in the performance testing/engineering genre.
Performance testing stands as one of the most crucial aspects of ensuring seamless functioning of applications. As organizations strive for innovation and rapid releases, the significance of evaluating softwareperformance throughout its lifecycle becomes increasingly paramount.
trillion this year 1 , more than two-thirds of the adult population now relying on digital payments 2 for financial transactions, and more than 400 million terabytes of data being created each day 3 , it’s abundantly clear that the world now runs on software. With global e-commerce spending projected to reach $6.3
In the previous installment of this blog series , we explored how to set up Dynatrace as a build-stage orchestrator to effectively address the challenges faced by Site Reliability Engineers (SREs). This can lead to a lack of insight into how the code will behave when exposed to heavy traffic.
34 (2020), Performance Testing with David Daly , is another good introduction. These two papers provide many more insights: Automated system performance testing at MongoDB , DBTest 2020 [ Video ]. The Use of Change Point Detection to Identify SoftwarePerformance Regressions in a Continuous Integration System , ICPE 2020 [ Video ].
by Jason Koch , with Martin Spier , Brendan Gregg , Ed Hunter Improving the tools available to our engineers to help them diagnose, triage, and work through softwareperformance challenges in the cloud is a key goal for the cloud performanceengineering team at Netflix. Charts are now resizable and movable.
Organizations use it to collect and send data to a backend, such as Dynatrace, that can analyze softwareperformance and behavior. Before OpenTelemetry and the W3C Trace Context open standard that underpins it, observability vendors had to reverse-engineer tracing libraries.
Standards boards, such as the W3C for the internet, IEEE for engineering, computing and technology, and CNCF for cloud-native computing, provide clearing houses and guidelines for these standards. Organizations use it for analyzing softwareperformance and behavior. At its foundation is the W3C open standard Trace Context.
In this Quality Sense episode, Federico Toledo has a chat with Júlio de Lima , an engineer at Capco, who recently completed his master’s degree in Electrical Engineering and Computing (Artificial Intelligence) and also co-founded GaroaQA , a meetup group with four locations across Brazil and over 2,000 members. Episode Highlights.
When it comes to organising engineering teams, a popular view has been to organise your teams based on either Spotify's agile model (i.e. One thing stand-out to me is being intentional and practical about your engineering organisation design. squads, chapters, tribes, and guilds) or simply follow Amazon's two-pizza team model.
There are many great blog posts: Performance Best Practices 7-parts series. Through the Looking Glass: Analyzing the interplay between memory, disk, and read performance. You may check The MongoDB Engineering Journal and the list of papers for more. Tips and Tricks for Query Performance: Let Us.explain() Them.
In today’s fast-paced digital landscape, ensuring high-quality software is crucial for organizations to thrive. Service level objectives (SLOs) provide a powerful framework for measuring and maintaining softwareperformance, reliability, and user satisfaction.

You shouldn’t wait until the end of the waterfall process to figure out where you are – on every iteration you can track your performance against requirements and see the progress (making adjustments on what is already implemented and what is not yet). At least not in their traditional form.
When the JavaScript engine runs a garbage-collection process, the man object will be removed from memory and from the WeakMap that we assigned it to. As we know from the section on garbage collection above, the JavaScript engine keeps a value in memory as long as it is reachable. Comparing Map and WeakMap.
Built-in, high-performance ML algorithms, re-engineered for greater, speed, accuracy, and data-throughput. Amazon SageMaker then sets up the distributed compute cluster, installs the software, performs the training, and tears down the cluster when complete.
Chaos engineering answers this need so organizations can deliver robust, resilient cloud-native applications that can stand up under any conditions. What is chaos engineering? Chaos engineers ask why. Practitioners subject software to a controlled, simulated crisis to test for unstable behavior. Hypothesis.
Correctness guarantees assure that an algorithm produces the right output for all valid inputs, forming the foundation of reliable software. Performance guarantees provide bounds on time or space complexity, crucial for understanding algorithm efficiency. This involves using algebraic rules and equivalences to transform expressions.
When trying to develop a new piece of software or an app, one of the first things a developer has to do is pick a programming language. Guest Post by Wendy Dessler. Source- Pixabay. For years, the debate has raged on regarding which programming language is better, Java or Scala.
Unit testing is one of the types of software testing where the smallest functional unit of code or software components is tested. The purpose is to endure that each unit of the softwareperforms as expected. It is a White Box testing technique mainly performed by the developers.
