Interesting lecture on microservices in ecommerce.
It turns out that at Best Buy, updates used to occur once a year, involving 60 people and taking 8 hours, usually overnight.
Refers (actually it doesn’t, I googled this) to Joel Crabb, Vice President at Target, who at that time was the Chief Architect at Best Buy. As Joel Crabb wrote on his website in A DIGITAL ECOMMERCE TRANSFORMATION – FRONT END MADNESS – PART II, before it was removed (but Google remembers everything), “A minor digression on the state of the ATG system is necessary to understand what we were dealing with. The original ATG system was built in 2003, at the time it was an excellent decision for a mid-sized retailer to build its first ecommerce engine. But over time, and numerous one-off projects, the code base had morphed, intertwined and been generally neglected and abused. As an example, one ongoing project when I arrived was to widen the product detail page (PDP) and move the Add To Cart button from the left side of the page to the right side. This seemed fairly innocuous, but it took six months and well over one million dollars to accomplish this task.”
Reading Joel’s memoirs is quite interesting http://joelcrabb.com/?paged=7&p=339
