Use Visibility & Facts to Avoid Lengthy War Rooms & Miscommunication

A few days back I was called into a war room situation with the hosted services group of our partner hybris. They were facing issues with the eCommerce site of one of their customers, a large UK based luxury clothing retailer. The situation was quite critical.

We run more than half of our data center for them!” At first I found this to be a bit difficult to believe, but then they shared real ... More >

“Production is where performance matters most, as it directly impacts our end users and ultimately decides whether our software will be successful or not. Efforts to create test conditions and environments exactly like Production will always fall short; nothing compares to production!” These were the opening lines of my invitation encouraging performance practitioners to apply for the recent WOPR24 (Workshop On Performance and Reliability). Thirteen performance gurus answered ... More >

Black Friday Night – Saving your eCommerce business – Real Time!

It's Black Friday in the US! For me it's actually already early Saturday being located in Europe. The past hours I spent on troubleshooting eCommerce sites that went down during their Black Friday peak sales periods. My friends at hybris kept me in the loop with their effort on keeping their customer's commerce sites up and running. I thought to share my experience of analyzing the root cause on four sites powered by hybris. None of these problems took me longer than 15 ... More >

Cool new stuff on the NGINX front

Although NGINX conf 2015 took place back in September, not a day passes without someone asking me to summarize highlights from the event, future NGINX plans, what's coming up, and related information requests, so I prepared this blog as an update on "what's up with NGINX". But first, I would like to once again thank the NGINX team for organizing a fantastic (sold out) event at a a very cool venue: Fort Mason, San Francisco. With over 600 registrations the annual event was ... More >
