When undertaking system migrations, one of the main challenges is establishing confidence and seamlessly transitioning the traffic to the upgraded architecture without adversely impacting the customer experience. These include options where replay traffic generation is orchestrated on the device, on the server, and via a dedicated service.

I had a professor in grad school who used to joke that all architecture is reinvented every 5 years. Both virtualization and power burst onto the architecture community seemingly out of nowhere even though there was a clear historical basis and trend for both. Virtualization, for instance, was being addressed by IBM in the 1960s.

For all HTML responses, I pass a Cache-control: max-age=900, must-revalidate header. This tells the browser to cache the response for 15 minutes ( 900 ⁄ 60 ). After that, it has to revalidate—basically, talk to the server again to make sure the asset is still valid and a newer version isn’t available.
