mobile DevOps

Mobile DevOps is a modern approach that enables seamless application delivery from testing to production. Modern agile teams need fast iterations and short feedback loops and CI/CD is what technology enables that. The role of the mobile developer has changed, from only being able to code to be able to build and provide an engineering solution. Now developers are required to have DevOps skills in their skillset, that way it makes life easier not only for QA but for the whole team, deploying and delivering applications with a breeze.

   ● Business was a driver
   ● Monolith

   ● QAs were struggling. Low test coverage and distribution
   ● Rollbacks were hard

6. Life before DevOps - Tech-wise
   ● Sysadmins = Bottleneck
   ● Staging server?
   ● Containers? Nope
   ● Software vs Hardware
   ● Long-living branches
   ● Merging
   I believe some of you still remember pushing changes directly to prod server via
   FTP
