ibabu Posted July 15, 2015 Report Posted July 15, 2015 When looking into each tool some themes consistently arise. It is frequently stated that Puppet is a tool that was built with sysadmins in mind. The learning curve is less imposing due to Puppet being primarily model driven. Getting your head around json data structures in Puppet manifests is far less daunting to a sysadmin who has spent their life at the command line than ruby syntax is. Chef on the other hand is procedural, you write your recipes in ruby code. If you're on the Dev side of DevOps, particularly if you already have ruby experience, this approach feels natural to you. If you're a sysadmin it can be more problematic. The steep learning curve of Chef is also viewed as a risk in larger companies. Skilling a large team up, and then maintaining those skills over time, is seen as a additional risk. The flip side to this argued by Chef users is that, once you are over the initially steep learning curve, you get a lot more power and flexibility out of Chef. Its reliance on code means you can bend configurations to your will much more easily. They would also argue that the model driven approach of Puppet, which determines installation based on defined dependencies, suffers in practice due to the loss of control. When defining procedurally there are no surprises. It should also be pointed out that Puppet now allow developers to work with pure ruby to build manifests (as of version 2.6).

k2s Posted July 15, 2015 Author Report Posted July 15, 2015 Yep its called rolling deployment unlike code push that takes downall servers at once and brings all ON at once rolling deploy via chef does it , one node at a time and then moves on to another, it even has excellent retry mechanism kothaga vintunna.. is it also called continuous deployment ?

sattipandu Posted July 15, 2015 Report Posted July 15, 2015 kothaga vintunna.. is it also called continuous deployment ? porabadddav Continous Integration veru , rolling deployments using chef veru
ibabu Posted July 15, 2015 Report Posted July 15, 2015 porabadddav Continous Integration veru , rolling deployments using chef veru So chef is like another puppet antaav..pedda theda em ledu ?we use puppet.

We dont change Db structure that often if we add or drop columns and do something related to DB , we have flyway scripts that do the task for us and yes they are part of our code base. We have intentionally not moved these steps out of codebase coz like i said earlier we dont do much changes on the DB side and taking a snapshot of DB and preserving it in case of flyway script failure , is also addressed in the process
