Microservices challenges fluster even the sharpest IT shops

Freed from the needs of a large and traditionally structured application, a development team working in the microservices architecture builds apps via services that can be more easily isolated, manipulated, updated and fixed. Still, developers and IT professionals should expect to encounter some microservices challenges as they make the switch.

One of the reasons IT organizations turn to the microservices architecture is to free themselves of the many unavoidable burdens inherent in monolithic applications. When done well, building in modules can greatly ease those burdens.

Among the biggest microservices challenges is the need to resist those habits formed when working in more traditional architectures. Those bygone ideas simply won't mix with the requirements of microservices. Mistakes and those old ways of thinking will get in the way of results and possibly even sink a microservices project.

Dependencies and configurations are too easily mishandled -- especially if development teams approach them with traditional and outdated IT mindsets. Some organizations will stumble in their microservices efforts by creating a microservice that's simply too small for the task at hand; others will encounter trouble by building them too large.

There is plenty that can go wrong when you are getting started in microservices. Bad things will result not necessarily from technical failings, but from a failure of imagination and plain old inertia. Applying the wrong thinking to microservices is, in effect, how an organization inadvertently sabotages an initiative.

TechTarget's Jan Stafford delves into these microservices challenges with her feature story in this issue of Modern Stack. She talks with experts about where these projects go wrong and how the missteps can be avoided.

Also in the new Modern Stack are features and columns that explore the role emotional intelligence plays in organizational change, how geography and specialty affect a tech worker's salary, why infrastructure as code deserves a closer look, how advances in big data may punish those who wait too long to get started, and why the pace of cloud innovation may begin to slow as hyperscale providers focus more on keeping their enterprise customers happy.
