If I'm putting this all together correctly, this may be the last part of the SHARES to homegrown, cloud-native, PSS that they've been working on for years. These details were revealed in 2 different AWS re:Invent sessions late last year, you can watch them and . Before seeing those sessions, I knew lots of customer facing entry points, app and website support, etc. were running on AWS, but it sounds like they truly just wrote their own PSS from scratch starting many years ago and have been cutting over aspects from SHARES ever since. Given UA is an industry leader in technology, I'd expect this to go relatively seamlessly and the time frame they quote is worst case scenario. This isn't your grandpa's Apolo to SHARES transition of 14 years ago.
