How the BBC works• One
domain• Two technology stacks• Cert’s and SSL• ProxyPass’• Apps are a TLD• 360+ apps• Everyone shares everything Okay there are several but they are all really the same one. Okay, three if you are going to be picky. Yes really, everything!
Performance Overview• Did find problems
– Weren’t found on stage• In all architecture layers• Components believed to be “fine” were not• Stage is not suitable for this level of testing• Proposal for any future “high profile” event• CDNs didn’t really get tested
Other problems• Running a “fake”
Olympics – That is invisible to the public – Did consider publicising a test• No A/B (bucket) testing capability• Some tests affected BAU• No real test of the HLS HDS streaming• Platform monitoring cycle
Other problems• RCA complicated by
shared platform• Testing stopped by BAU/TX• High reliance on key staff – Some tests suffered• No CDN testing – At their request – Places unfair load on infrastructure• Unable to simulate network congestion
