3 Challenges of Microservices

Microservices trends have become an important part of corporate strategy and are no longer considered just another technology fad.? ?

Though, microservices bring many benefits to the organizations, they do come with their own unique set of challenges. It’s important to address the implementation challenges before actually proceeding with the process. Here are three common challenges that you may encounter while implementing microservices, and suggestions on how to overcome them.?

1. Design ?

When?adopting microservices architecture for the first time, organizations often struggle to determine the: ?

• Size of each microservice ?
• Optimal boundaries between the microservices ?
• Framework for integrating services?

And to establish the overall framework of a microservice, you need to keep your initial focus on building it within a limited context (business capability) only. Each microservice needs to have a clear and specific responsibility. Furthermore, you must avoid prioritizing data-centric approach when modelling a problem domain for data is meaningless without logic. Instead, start with context and logic to design integrated microservices.?

2. Monitoring?

Microservice architecture ensures your app’s functioning even when some services fail, however this resiliency comes at a price. Identifying the specific failed service becomes particularly difficult through manual monitoring and testing methods. And if not identified sooner, may result in simultaneous service failures and consequent loss in app functionality.

Therefore, to counter this you need to have a comprehensive, automated monitoring program that identifies the service failure source rapidly.?

3. Testing ?

While implementing microservices, organizations lack in integrating and testing the approach, adding to the complexity. ?

To reduce the complexity of each service, you need to test each service individually. This makes the development process for each service simpler and direct. ?

Deploying microservices may seem like a daunting task, but splitting them into steps makes it much easier to manage. ?
