Microservices: Friends or Enemies?

Nowadays business environment is as competitive as never, so any company, no matter its specialization or size, needs to innovate at a faster rate to stay ahead of its competitors. To mitigate the risk of disruption, InToSoft company follows and strives to apply latest software development trends including microservice architecture as we consider it the perfect fit for agile software creation to enable more effective delivery of value. Though “microservices” is quite a new word in the development community, we have already successfully implemented this technique while working on some customer projects and now we are ready to speak about its advantages and disadvantages basing on our own experience.

So, what are microservices and what they are used for? The idea behind microservices is that some type of applications can be created in a faster and easier way when they are broken down into smaller units which are developed separately but when composed work as a whole system. Thus, the application becomes the sum of such pieces.

Many software developers consider this approach an easier way to build a range of applications including some enterprise apps and Internet services. But why they think so?

Basically, there're four key reasons to choose microservice architecture when creating the application:

Resilince. The technique improves fault tolerance as larger applications can be largely unaffected by a failure of a single piece. If there’s any fault, development teams can break down functionality to the basic level and then update only the relevant components instead of launching the painful process of integration typical for monolithic solutions. Thus, microservices speed up development processes, significantly reducing time for development and its cost.

Efficiency. Each microservice requires small development teams which need little coordination between them and which can move independently.

Agility. Software development specialists can use any language, frameworks and libraries they deem best for the problem at hand instead of one size fit’s all.

Revenue. Faster iterations and decreased downtime can significantly increase revenue. User engagement and retention enhances with continuous improvements offered by microservices.

However, despite all its benefits MSA is not a silver bullet that can solve all the problems of software systems. For example, data transfer between microservices as well as their serialization and deserialization can appear to be quite expensive. Moreover, the possibility to use different technology stacks when building the application may evolve the problem of non uniform solution design and architecture what can result in maintenance cost increase.

Nevertheless, microservice architecture remains one of the best ways to build the system if it’s expected to be too complex or too big to manage or to handle high traffic & load and needs to be highly scalable. However, for applications that are not intended to become too big to manage in the future, it is better to keep it at the monolithic architecture. Still, every project owner who intends to build his own solution should consider both microservices and monolithic development.
