As a result, he says, a microservices approach not only "frees up release processes," but it also eliminates "giant integration tasks at the end of every month." Instead, he explains "we can move to weekly releases, even subweekly releases for pieces of the system." "Microservices is about isolating parts of the products, and pieces of code, so that changing one piece of the architecture does not require us to re-release all of it," says Clay Garrard, senior manager of cloud services and architecture at Disney. Launched in September, Public Cloud Manager is an auditing tool that allows users to determine if their services and applications are in compliance with Disney's public cloud security policies.ĭeveloped with the assistance of IT management consultancy Clutch, Public Cloud Manager represents a significant departure from Disney's traditionally monolithic approach to building tightly coupled services. The company's first modular project is dubbed Public Cloud Manager. IT complexities and cultural adjustments haven't dissuaded Disney from testing a microservices architecture. "We're seeing too many people jump on the bandwagon before getting ahold of some of the core concepts and capabilities that you need before moving to full-on microservices," warns Molly Bartlett Dishman, a senior consultant at ThoughtWorks, a global IT software consultancy. Some question the impact that microservices' moving pieces can have on an IT team's productivity, while others caution that making microservices work requires organizational and cultural adjustments. After all, breaking down systems into tiny, modular pieces can add layers of complexity to an IT environment. But while modular software design is a hot trend, many observers question whether microservices have much practical real-world utility.
