Microservices for Non-Technical Managers: Benefits, Pros and Cons in Application Development


App developers have a common desire of reaping the highest possible return on investment. However, few of them manage. The first move you should think of is to give your app the competency it deserves by ensuring it has maximum reliability and agility. Microservices is becoming a buzzword in the current technology-driven world. Microservices refers to an exclusive architecture for distributed development of software systems. It has become the most desirable way of creating enterprise applications. It is basically a distributed system of a larger application (monolith) to form separate smaller services that make your system functional. These small units are referred to as microservices. They are responsible for handling smaller possible functionalities such as communication, HTTP requests, database operations, and execution of domains, handling of clients, authentication and much more.

Modern businesses are moving the microservice way. Think of an instance when your application has to handle many services at a go. Your app can easily suffer from overloading and can lead to performance issues if it lacks integrity. Microservice enables you to scale your app and make the running of multiple services efficient. How these services communicate with one another is determined by the requirements of your application. Microservices is a perfect alternative for traditional monolith service where all the change cycles get tied up. In such a case Microservices can rescue you to a great extent.

Why should you consider Microservices?

Well, as a success-oriented developer, microservices architecture can benefit you to a great extent in accelerating the success of your app. Here are some reasons why moving the microservice way is the best way to go in app development.

It can be aligned with several technologies

The developer must empower the microservices during adoption for it to be successful. Currently, Docker container and PaaS solutions have revolutionized everything making it easy and flexible for technology enthusiasts to deploy anything that works for their app. Besides, it does not call for any special IT processing. Since microservices enables you to adopt several new technologies with ease, you can motivate and influence many young engineers and other pioneers who may be willing to work with you.

Added agility

Customer experience matters in determining whether users will come back for the services of your app or not. Microservices make development organization flexible and highly responsive. It works regardless of whether you are adding a new feature or want to improve the performance of an existing feature. Each microservice can be released and deployed independently.

Efficiency in development

Unlike in the monolith technology where you are restrained to conventional technological processes and stacks, microservices architecture enables you to choose the most appropriate processes and techniques that fit your enterprise. Take the instance of payment where PCI standard says all code base that handles data related to credit cards be subjected to compliance audits. Therefore, when payment processes are handled by one or group of microservices, the number of codes in the scope is significantly reduced.

Scalability in costs

Microservices architecture allows for a more granular approach where you can scale every individual microservice. It is advantageous compared to the traditional monolith where you had to scale the entire app when it reaches the peak point. Here, you only add new features to an individual microservice where the problem emanates and not the entire app.

Easy maintenance

Application development is one factor, and maintenance is another. Your work does not end after the completion of your development process. Maintenance is vital in keeping the integrity of your app. In microservices architecture, every microservice deals with only one purpose. It means there is limited codebase which translates to simple maintenance.


  • You get maximum freedom to develop and deploy your services without following any standard rule
  • You can write your codes in any of your preferred language.
  • It is very easy to integrate and deploy. In fact, you can use open-source services such as Jenkins and much more.
  • You can easily isolate any service that malfunctions to maintain the functionality of your application.
  • You can customize codes to suit different enterprise needs.
  • Since it is easy to scale, you can integrate with other business and third party processes.
  • It enables you to use the latest technologies meaning you remain updated.


While microservices promise many benefits, some challenges come with it. Some of them include:

  • Testing can be compromised.

Microservices involves the use of a distributed deployment. In such a case, testing of your application can be tedious and complex. This is a major drawback you can encounter when using the architecture to develop your app.

  • Several services can be a barrier to effective communication

Since you are allowed to use several services, sometimes this can be a big problem especially if you use many of them as it can complicate the entire system. Besides, it can also result in excessive memory consumption.

  • Splitting the app into individual services is tedious

Though the technique is desirable, it is not an easy thing to divide and subdivide the component services. It is a demanding task. Furthermore, you also have to put additional effort to ensure that there is a good integrity and communication between the services in your application. You have to deal with the complexity of the entire system.


Microservices architecture offers the most desirable way of designing and implementing various enterprise applications. As a developer, you can use the approach in leveraging APIs. Many organizations and developers have successfully adopted it. However, when using the method, there are two things you need to keep in mind i.e. application resiliency and enabling of loosely coupled services. Your services need to have properly defined protocols for effective communication.
