How to implement the [immutable server] pattern without loosing the ability to do [post-mortem]s?
added by Michael Grünewald Apr 2 at 6:39
link|flag
Just to clarify, the immutable server pattern usually involves removing ssh or more generally administrative access to the machine, which can be an obstacle for post-mortems. – Michael Grünewald Apr 18 at 11:38

How to achieve a smooth transition from “the one big VCS repository for all projects” organisation model to the “many small VCS repositories” model?

This is a good question imho; maybe specify "scv repository" to make it more clear. Or the transitioning from monolithic to microservice architecture – guido Apr 2 at 10:08
Of course this is about testing and deploying – at the SCV level, this is an easy task. – Michael Grünewald Apr 2 at 15:33

@hector-valverde-pareja Thank you for your interesting questions! There is a misspelling in the title of this one. :) – Michael Grünewald Apr 26 at 19:14
Apologies, English is not my mother language. I don't see the error though? Could you illustrate it, please? – Héctor Valverde Pareja Apr 26 at 19:17
You probably meant CloudFormation instead of ClourFormation. :) – Michael Grünewald Apr 26 at 21:06
Ops! Just Fixed! – Héctor Valverde Pareja Apr 26 at 21:14

Addendum as it can't fit int he tittle: I'm pretty sure this question can be a good fit and give a proper comparison table as answer, splitting it on each type would scatter the information and comparison with other types would be needed anyway. – Tensibai Apr 4 at 8:19

@Tensibai agreed; in my view, this proposal would have this kind of comparison questions at its very core. – guido Apr 6 at 14:33

If by rigid you mean defined and automated, this is a good question. – Adam Berry Jul 8 at 17:14
If this is what you mean, maybe “formalised” is a better match than “rigid”. – Michael Grünewald Aug 12 at 15:34

Maybe you could give a hint at the type of service you want to make highly available? This type would influence the consistency of operation or telling if the service operates in read-only mode or in read-write mode. – Michael Grünewald May 6 at 22:34

Maybe you want to rephrase this as “How to implement CI and CD for iOS apps using managed services” rather than asking for a service recommendation. I think this wording is more likely to attract good answers. See discuss.area51.stackexchange.com/questions/22781/… – Michael Grünewald Apr 28 at 8:56
Thanks for the advice Michael! – Felipe Plets Apr 28 at 13:06
