Impact of Third-Party Tags on Performance: Take II By Dawn Parzych Two years ago, we published an ebook on the True Impact of Third-party Tags. A lot can change in two years, especially when it comes to technology, so we felt it was time to revisit the sites we tested. In 2015, we analyzed sites across four verticals – US banking, ecommerce, news, and travel – to see what impact third-party tags have on page weight, response times, and the number of requests. We conducted the same analysis on these sites based on data from November 2016, during which over 600,000 test runs were analyzed. If I said I had no assumptions going into the analysis, I would be lying. There are always assumptions or hypotheses involved in an analysis such as this. Here were a few of mine: Average page sizes would  increase Percentage of third party requests would increase Response times woul... (more)

[session] Cloud Sprawl: The Rising Epidemic By @Citrix | @CloudExpo #Cloud #WebPerf

Cloud Sprawl: The Rising Epidemic and What to Do About It Wooed by the promise of faster innovation, lower TCO, and greater agility, businesses of every shape and size have embraced the cloud at every layer of the IT stack - from apps to file sharing to infrastructure. The typical organization currently uses more than a dozen sanctioned cloud apps and will shift more than half of all workloads to the cloud by 2018. Such cloud investments have delivered measurable benefits. But they've also resulted in some unintended side-effects: complexity and risk. End users now struggle to navigate multiple environments with varying degrees of performance. Companies are unclear on the security of their data and network access. And IT squads are overwhelmed trying to monitor and manage it all. In his session at 20th Cloud Expo, Tim Minahan, Senior Vice President at Citrix, will e... (more)

Causation and Correlation in #Monitoring | @DevOpsSummit #DevOps #APM

Causation and Correlation: What Difference Does It Make? By Joseph Hoffman Causation and Correlation: What’s the difference? Why does it matter? Does it matter? Some vendors use time-based correlation to connect events across multiple observed data sets, and claim there’s a connection between two observed data sets. This type of approach is flawed and can lead to wildly inaccurate conclusions, which itself leads to wasted time by technical teams and high cost to the business. In the chart below we observe the Number of Requests and the Memory Utilization. Wow, the increase in the Number of Requests is causing memory utilized to go up. Quick, call Engineering and get them on this right away. We can easily see that there’s a correlation between the Number of requests and the memory size. Based on this data it would be relatively easy to conclude that the increase in R... (more)

Building a Winning DevOps Team | @DevOpsSummit #API #Agile #DevOps

Guest Post: Building a Winning DevOps Team By Adi Glasman DevOps, and Ops in general, is one of the most important components of a company’s production machine. Investing in building a winning DevOps team should be a priority for every company and will pay off quickly. As organizations and operations grow (products, features, number of customers, etc.), the scale of traffic, data, OS types and so on, increase rapidly. More products to support, new features to release and a lot more in-house cycles (e.g., QA, CI\CD, SME, SRE) need to be managed. A DevOps team’s first mission is to build, maintain and support the company’s technology stack. Whether it’s a PaaS, SaaS or IaaS environment, microservices or monolithic, Docker or K8S, it does not matter – DevOps engineers need to be able to support any environment the company chooses at any time and anywhere (On Premises, ...

[session] Measure Twice, Correlate Once | @CloudExpo @Catchpoint #WebPerf

Measure Twice, Correlate Once: Understanding How to Correspond IT Performance to Business Performance Tricky charts and visually deceptive graphs often make a case for the impact IT performance has on business. The debate isn't around the obvious; of course, IT performance metrics like website load time influence business metrics such as conversions and revenue. Rather, this presentation will explore various data analysis concepts to understand how, and how not to, assert such correlations. In his session at 20th Cloud Expo, Leo Vasiliou, Director of Web Performance Engineering at Catchpoint Systems, will review data analysis basics, and then move into some data-to-actionable information concepts. Afterward, YOU decide whether to use your newfound knowledge for good or evil. Speaker Bio Leo Vasiliou is the Director of Web Performance Engineering at Catchpoint Syst... (more)

Insane in the Mainframe? By Lisa Wells This is the burning question these days for the great minds of the enterprise regardless of industry! The digital revolution changes the way we do business and enables a world of new possibilities.

What Is #DevOps Intelligence? | @DevOpsSummit #AI #ContinuousDelivery

DevOps Intelligence Changes the Game By Lisa Wells One of my favorite parts of the novel The Phoenix Project is when Bill Palmer, DevOps hero and VP of IT Operations for the fictional company “Parts Unlimited” has a light bulb moment about the central importance of IT to the business. The moment comes as the company’s CFO lays out for Bill how he strives to align the goals of his department with the goals of the business. It’s here Bill starts to realize he must take a similar approach with IT. He ultimately turns to data about his delivery process to improve IT’s effectiveness and save his team from outsourcing—and a DevOps team is born. Okay, so real-world situations might not be as dire as the fictional drama at Parts Unlimited. Still, many IT teams that are transforming to DevOps have yet to take the next step—using “DevOps Intelligence” to make data-driven dec... (more)

Five Network Metrics | @CloudExpo @AppNeta #APM #SaaS #AI #DataCenter

Five Network Metrics for a Cloud World By Christine Cignoli As the network has moved from a physical entity to a more abstract one, IT has valiantly kept pace by researching and deploying new network devices and functionality. IT teams have had to shift workloads and mindsets to the cloud and to SaaS providers, while remaining responsible for end-user experience-which is ever more important. It's a tangled web in the networking world today, but all is not lost. We recommend these five metrics as the building blocks to measuring end-user experience and network performance in the cloud. They'll likely look pretty familiar: They're the same old metrics as were useful in the pre-cloud world, and can offer valuable insights now, too (though you'll need to be able to see into the cloud to get them - AppNeta can help with this). 1. Latency. This metric measures the time it ... (more)

ChatOps Interface | @DevOpsSummit @VictorOps #DevOps #IoT #ChatOps

ChatOps: The New Interface of DevOps Download Slide Deck: ▸ Here The modern software development landscape consists of best practices and tools that allow teams to deliver software in a near-continuous manner. By adopting a culture of automation, measurement and sharing, the time to ship code has been greatly reduced, allowing for shorter release cycles and quicker feedback from customers and users. Still, with all of these tools and methods, how can teams stay on top of what is taking place across their infrastructure and codebase? Hopping between services and command line interfaces creates context-switching that slows productivity, efficiency, and may lead to early burnout. The teams and organizations that are leading the DevOps movement have turned to their chat client to provide a new interface. We are already in chat all day, sharing, collaborating, and con...

Production Deployments | @CloudExpo @DaliborSiroky #APM #ML #DevOps

Production Deployments Don't Have to Be a High Wire Act By Dalibor Siroky It's 3 am in California, and you are still awake trying to sort through a release process that has been delayed by several hours. The deployment to the main application cluster took several extra hours due to an unanticipated problem with the servers, and now everyone is waiting on the lead database administrator to call into a conference bridge so you can all move on to Step 53.5b of the deployment. Your production deployments always seem to be problematic and this one might be the worst you've experienced yet. Everyone's Tired: Bad Decisions Abound By "everyone," I mean the 30 QA testers and 3 project managers in California, several developers in Sydney and India, and an operations team spread throughout the EU and the US. You can tell by some of the ambient noise on this conference call that... (more)
