How to implement the [immutable server] pattern without loosing the ability to do [post-mortem]s?
added by Michael Le Barbier Grünewald Apr 2 '16 at 6:39
link
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 Le Barbier Grünewald Apr 18 '16 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 '16 at 10:08
Of course this is about testing and deploying – at the SCV level, this is an easy task. – Michael Le Barbier Grünewald Apr 2 '16 at 15:33

If by rigid you mean defined and automated, this is a good question. – Adam Berry Jul 8 '16 at 17:14

If this is what you mean, maybe “formalised” is a better match than “rigid”. – Michael Le Barbier Grünewald Aug 12 '16 at 15:34

@hector-valverde-pareja Thank you for your interesting questions! There is a misspelling in the title of this one. :) – Michael Le Barbier Grünewald Apr 26 '16 at 19:14
Apologies, English is not my mother language. I don't see the error though? Could you illustrate it, please? – Héctor Valverde Apr 26 '16 at 19:17
You probably meant CloudFormation instead of ClourFormation. :) – Michael Le Barbier Grünewald Apr 26 '16 at 21:06

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 '16 at 8:19

@Tensibai agreed; in my view, this proposal would have this kind of comparison questions at its very core. – guido Apr 6 '16 at 14:33

How to implement CI and CD for iOS apps using managed services?

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 Le Barbier Grünewald Apr 28 '16 at 8:56
Thanks for the advice Michael! – Felipe Plets Apr 28 '16 at 13:06

Maybe you can reformulate this question with a more devops-y perspective. For instance, asking more specifically how easy it is to maintain your deployment scripts using the two strategies. – Michael Le Barbier Grünewald Jun 28 '16 at 7:14

How can I create a high availability cross-region [VPN] in [AWS]?
added by Héctor Valverde Apr 23 '16 at 18:35
link
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 Le Barbier Grünewald May 6 '16 at 22:34

Hi Michael, sorry for the late response. Regardless of the service I want to deploy in AWS, what I want to make HA is the VPN itself. Currently, AWS doesn't provide a secure network between regions, so you need to create your own VPN, say using any IPsec service in EC2 instances in different regions. The problem is that achieving redundancy and load balancing seems to be quite difficult in this scenario. – Héctor Valverde Oct 10 '16 at 14:08

Hi Hector, thank you for clarifying this, this is indeed a very interesting question. – Michael Le Barbier Grünewald Oct 19 '16 at 13:09
