Today, I am happy to introduce the new AWS Asia Pacific ( Hong Kong ) Region. AWS customers can now use this Region to serve their end users in Hong Kong SAR at a lower latency, and to comply with any data locality requirements. The AWS Asia Pacific (Hong Kong) Region is the eighth active AWS Region in Asia Pacific and mainland China along with Beijing, Mumbai, Ningxia, Seoul, Singapore, Sydney, and Tokyo.

My previous post presented “A Graphical View of API Performance Based on Call Location.” In that post, we analyzed the performance of a week of calls to the World Bank Countries API (which is served from Washington DC) from four different locations around the globe: Washington DC, USA; Oregon, USA; Ireland; and Tokyo, Japan. The API performance across the week showed remarkable consistency.

All of the popular speed testing tools typically provide a page speed score along with their objective results. Google PageSpeed Insights has a their “Speed Score.” Pingdom has a “Performance Grade.” WebPageTest has their five A-F grades. While these do have a purpose, most people use them incorrectly, in a way that can be dangerous to your real site speed.

Selenium locators are key when dealing with locating elements on a webpage. From the list of locators like ID, Name, Class, Tagname, XPath, CSS selector, etc., one can choose any of these as per their needs and locate the web element on a web page. Since ID’s, name, XPath, or CSS selectors are more frequently used as compared to tagName or linktext , people majorly have less idea or no working experience of the latter locators.

End-to-end testing is one of the most effective ways to ensure end-user application performance. In a microservices-based, Agile-driven world, software development and delivery have become quite complex. Today’s applications are built on layers of code, networks of subsystems, and third-party integrations that are so intertwined, if one fails component fails, so does the entire product.

Edge Perspectives

APRIL 24, 2019

In a book I wrote 20 years ago, I identified an opportunity that has yet to be addressed, but is becoming more and more attractive. Sometimes when you’re on the edge, it takes a little more time than you thought for opportunities to emerge in practice. The book is Net Worth: Shaping Markets When Customers Make the Rules and I wrote it with my friend and collaborator, Marc Singer.

During my presentation at Percona Live 2019 I will show how using Optimizer Trace can give insight into the inner workings of the MySQL Query Optimizer. Through the presentation, the audience will both be introduced to optimizer trace, learn more about the decisions the query optimizer makes, and learn about the query execution strategies the query optimizer has at its disposal.

Alan Page, who wrote How We Test at Microsoft and hosts a podcast about testing, once famously observed that testing, as a field, seemed stagnant. He proved his point by reviewing the sessions from a conference and showing how they were interesting today—even though that conference had taken place 10 years earlier.

People have a lot of opinions about the "new" Microsoft under CEO Satya Nadella. They've embraced open-source , including.NET Core. They declared Microsoft ? Linux. They acquired GitHub. It's been a wild ride for those of us used to the closed, dare I say grumpy Microsoft of the past. But are things different today? When the rubber hits the road, is Microsoft really more open, more accessible, more helpful?

Dynatrace news. Dynatrace provides automated end to end monitoring of applications under a single platform. Even if this is true, in practise there is only so much the one Agent can Autodiscover and fine tuning might be required. For instance, not all deployments follow best practise. I have worked with many customers and I found that in most cases, 90% of what was mapped automatically was fine however the remaining 10% needed fine tuning due to bad deployment practises.
