7 Challenges and Solutions for Microservices - Tips & Tricks

The corporate competition to lead the race is going tougher with the invention of new technology every day. Organizations are leaving no stone unturned to make sure that they serve to their best level to their customers by adopting reliable, scalable, and versatile applications. As a result, companies are switching over to newly emerged Microservices from their age-old monolithic systems. As organizations started to shift towards Microservices, various tech and other challenges emerged to pop up. 


Top 7 Challenges and Solutions for Microservices Architecture.


Problem 1: Uniform Access to Services


Microservices Architecture is composed of varied mini services requested by multiple consumers. Request from mobile app differs from that from a web browser and different services use different protocols resulting in a complex network to access the service.

Solution: To overcome the problem, the organization shall let the API gateway work as a single entry point to handle the entire service request. These APIs called by requests, will in turn route them to the desired service module to segregate the workload. 


Problem 2: Registry and Service Location


Microservices came into existence to ease the distributed computing world. Software is composed of various services that keep communicating with other services over the network. A problem arises when the service location keeps changing, as consumers need to access the exact location over a network.

Solution: System admin shall implement the registry for service maintenance with a record of all network locations. The user shall refer to this dynamic service registry in order to find the network location of any service in need.


Problem 3: Debugging & Logging


This architecture of Microservices uses the log system. Whenever a service is generated, it adds info to the log. Troubleshooting service is a nightmare, especially when the entire log is to be checked manually.

Solution: The finest and easiest solution to this problem is to maintain a common service for logging. Each service shall update the centralized log system which shall be a lot easier task to analyze. 


Problem 4: Monitoring


Initially, with the old system, the single application was managing multiple services. But with the advent of Microservices, each module of work is handled by a separate service. At the time of the problem, locating the root cause is a mammoth task.

Solution: It is advisable to have a centralized problem-finding tool. The monitoring tool is applicable at all the stages of the Software Development Life Cycle. It helps in identifying problems at the earliest stage and in minimum time.


Problem 5: Configuration


Microservices comes with yet another complex service configuration. Each service needs a separate configuration and is independent of the other. Until all necessary adjustments are made, it is cumbersome for any application to run in separate environment. 

Solution: System administrator shall opt for a centralized and common service for configuration. It shall be backed by a common repository in such a way that each and every services just have to request one single service to access the config file.


Problem 6: Authorization & Authentication


Security is the major concern with any software application and its modules. It is no different with Microservices architecture as well. A lot of emphases is put on its security as it has yet not made a strong and fruitful image of itself to be fully secured. Organizations still hesitate to implement many times before implementing the Microservices with fear of lack in security. 

Solution: The authentication service be common and placed in a centralized zone. Its main task shall be to authenticate all the customer's requests before granting them access to the system or services. Every single service shall be responsible and allotted the task of authenticating the user.


Problem #7: Version management


With so many services under one umbrella, creates a version mismatch error. If an API is being used by 2 or more services, and the first service is updated, the second one shall also be updated to match with the new API version.

Solution: Regular updation for all services shall be done and at regular intervals. This will sort out the dependency version problem. 

 


Conclusion

No matter that every organization that adapted to Microservices Architecture, has benefitted at large, but it came with its own set of challenges. One needs to learn from the past case studies and implement the solutions mentioned above. The valuable tips and tricks to utilize the full potential of Microservices will help one and all.
