    re:Cycle

    First +10 years of AWS service lifecycle management was just continous stream of announcements about new services and features. And many (most?) of the services that got out to public are still there with backwards compatibility all the way to the beginnings.

At some point you must start end-of-life process for features and services that no longer meet customer demand, have been replaced by more efficient alternatives or have become blocker for future development.

Unfortunately this combination wasn't supported at eu-north-1 -region. Ok, but there must be tons of examples how to add HTTP Basic Auth to ALB with Lambda ... but my googling produced no usable results.
