At Altoros, we love microservices, but despite all the benefits, this approach is not perfect. While eliminating many of the issues inherent to monolith apps, microservices may actually create some serious challenges, for example:<\/p>\n

  Implicit interfaces.<\/strong> When splitting a monolith into several collaborating components, you need to enable communication between different parts of the system. Microservices-based applications use interfaces for this purpose. For the communication to work flawlessly, messages must have a format and semantics that all your interfaces can read. Since all components are interrelated, when modifying one interface, you need to adjust all the other interfaces, as well. Otherwise, they will not be able to see the changes. So, if you use a microservices environment, simple cross-cutting changes will require modification of many different components.<\/p>\n<\/li>\n

• \n

  Significant operational overhead.<\/strong> Using a microservices architecture may increase operating overhead. With this approach, your deployment may require significantly more resources. As a result, you may need more time and effort to create the infrastructure.<\/p>\n<\/li>\n

• \n

  DevOps skills are required.<\/strong> Since the microservices model allows for using various tools and solutions to implement different services of the same system, you may need to use different data stores for different services. Your database administrator might have to be replaced by a developer with experience in deploying, running, and optimizing NoSQL databases (a developer with DevOps skills).<\/p>\n<\/li>\n

• \n

  Operational complexity.<\/strong> In general, it is more difficult to control a microservices architecture, since it consists of multiple instances and services that must be managed in production. To address this, you need to provide a high level of automation.<\/p>\n<\/li>\n<\/ul>\n
