  3. 3. DRAWBACKS DEPENDENT TEAMS SCALING ISSUES ADOPTING NEWER TECHNOLOGIES Teams become dependant on each other and the whole system starts moving with the speed of the slowest team member. Even well architected application that has a clean code structure, that uses several layers of caching and that has optimized database structure, will eventually reach its limit when deployed as a monolith. Monolithic applications has a barrier to adopting new technologies. Since changes in frameworks or languages will affect an entire application it is extremely expensive in both time and cost TESTING & RELEASE MANAGEMENT Even a small trivial bug fix needs full round of testing. Has very tedious release management, it needs to co- ordinated with all the team and need meticulous planning ©ThoughtWorks 2019

  5. 5. ADVANTAGES INDEPENDENT TEAMS SCALING NEWER TECHNOLOGIES CAN BE ADOPTED EASILY Teams don’t have to dependent on other teams. Scaling a particular service service is very easy Any new technology can be easily adopted TESTING & RELEASE MANAGEMENT Trivial bug fix doesn’t need full fledged test Each and every team can plan their release without worrying much about the other teams. ©ThoughtWorks 2019
