My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? Well, yes and no. I am not so upbeat as I was in 2014. If we speak about commercial load testing tools, we see rather a shrinking market and not too much innovation recently. If we speak about open source tools, we definitely see some improvement – but in many areas they are still behind the best commercial tools (yes, many may not need these adv
It’s true that what might be considered the “most important” or “best” web performance metrics can vary by industry. For example, a media organization may be interested in tracking Time to Interactive because its site relies on third-party advertising for revenue, while an ecommerce business might want to dig deeper into First Meaningful Paint so it can ensure that customers can quickly take action to purchase an item.
By Benoit Rostykus, Gabriel Hartmann Noisy Neighbors We’ve all had noisy neighbors at one point in our life. Whether it’s at a cafe or through a wall of an apartment, it is always disruptive. The need for good manners in shared spaces turns out to be important not just for people, but for your Docker containers too. When you’re running in the cloud your containers are in a shared space; in particular they share the CPU’s memory hierarchy of the host instance.

Test how your application will react when many users access it. When building your application, you probably test your application in a lot of ways, such as unit testing or simply just running the application and checking if it does remotely what you expect it to do. If this succeeds you are happy. Hooray for you, it works for one person! Of course, you’re not in the business of making web applications that will only be used by just one person.
Dynatrace news. Welcome back to the blog series in which we summarize the findings of our Autonomous Cloud Management Survey. In part 1 we examined the Dev-to-Ops ratios that organizations have for their most critical application projects. In this post, we’ll look at organizational silos, and how far organizations have come in breaking them down. To explore this issue, we asked participants the following question: Which of your teams have access to production monitoring data?

I hate to admit it, but five or six years ago my interest in web design started to wane. Of course, owning a business meant I had to keep working, but staying motivated and offering my best thinking to clients became a daily struggle.
Given the popularity of our post on connecting MongoDB SSL with Self-Signed Certificates in Node.js , we decided to write a tutorial on connecting MongoDB with Ruby. In this blog, we’ll show you how to connect to a MongoDB server configured with self-signed certificates for SSL using both the Ruby MongoDB driver and the popular Object-Document-Mapper (ODM) mongoid.
Amazon and a lot of cloud vendors such as Microsoft and Google have services around machine learning (ML), artificial intelligence (AI), and virtual assistants. A popular one that might come to mind is Amazon Alexa, something I’ve written quite a few tutorials around over the years. The concept around Alexa is simple. Provide the Alexa service some audio, have that audio converted into text or some other format that can be evaluated, execute some code, and respond with something to be spok

When building a web application there is a good chance you’re going to need to work with images eventually, even if it is something as simple as allowing a user to upload a profile image. In theory this is a simple task, but in reality, your website theme is probably anticipating images of a certain resolution or aspect ratio. If the user tries to upload an image that doesn’t meet your requirements, it might break your theme.
According to Michael Feathers, “Any code that has no tests is a legacy code.” So as a developer it is your duty to avoid creating legacy code by using test-driven development (TDD). There are many tools available for unit testing in ReactJS but we will be going through Enzyme and Jest.
Dynatrace news. When disaster strikes, it is important to react fast and get live updates on the recovery progress of the business and mission-critical systems. Dynatrace not only makes it easy to monitor all critical systems (hosts, processes, services, applications, users, network, cloud, custom devices, …) but thanks to the metadata the Dynatrace OneAgent captures for each entity, you can organize, filter, get alerted and get an overview of your system based on data that is relevant to the di
Data validation for machine learning Breck et al., SysML’19. Last time out we looked at continuous integration testing of machine learning models , but arguably even more important than the model is the data. Garbage in, garbage out. In this paper we focus on the problem of validation the input data fed to ML pipelines. The importance of this problem is hard to overstate, especially for production pipelines.

With so many different metrics available to measure dozens of different aspects of a web page, it can be a struggle to know how best to quantify that page’s overall web performance. In this post, we discuss why there are so many metrics, explore what is “the best” metric, and discuss how you can use the Lighthouse Score to better your own performance.
A while back, our friends at Shopify published this great case study , showing how they optimized one of their newer themes from the ground up – and how they worked to keep it fast. Inspired by that post, I wanted to dig a bit deeper into a few of the best practices they mentioned, which fall loosely into these three buckets: Analyze your pages – understand the critical rendering path and page composition.
Growing up in performance engineering in the last decade, it was almost impossible to think of simulating load using a real browser because a performance engineer would need a lot of machines to simulate load using a real browser. Performance engineers used to have a couple of desktop or servers to simulate hundreds and thousands of users load. Their preferred choice used to be to capture HTTP/s requests using tools like LoadRunner , JMeter , Soasta , and Neoload.
Dynatrace news. We’re happy to announce the launch of Dynatrace Synthetic private browser monitors!

Towards multiverse databases Marzoev et al., HotOS’19. A typical backing store for a web application contains data for many users. The application makes queries on behalf of an authenticated user, but it is up to the application itself to make sure that the user only sees data they are entitled to see. Any frontend can access the whole store, regardless of the application user consuming the results.
We are becoming more connected with each other and less connected with each other at the same time. The Big Shift that we're experiencing on a global scale is full of paradox – this is just one of many, but a particularly important paradox to acknowledge and address. Let’s explore the forces that are shaping both dimensions of the paradox. More connection.
