In the past few years, many companies have shifted from a monolithic to a microservices approach. However, as with any approach to application development, the microservices architecture has its own challenges.
There are several use cases where organizations noticed an increased complexity and effort to develop applications with a microservice framework.
This is what happened to one of our clients too!
Being a leading SaaS-based company in Sales and marketing, they wanted to do upgrades at will along with predictability.
And because their existing microservices were not well-managed in terms of deploying only the updated ones. They faced subsequent other problems too.

Challenges you Face When Your Microservices are not Well-Managed
- A small change of code would result in the deployment of almost all the services.
- Any modification had a significant impact, and even though the process is automated, testing may take a long time.
- Instead of click-button automation, upgrading is an activity itself that requires the entire team to collaborate.
How To Manage Poorly-Managed Microservices
The first step to solving any problem is to understand the situation well. The causes and the effects. This is why our automation experts first engaged with your team to understand the challenges & requirements.
Then, after understanding the challenges, the code structure, and the different microservices we take these key steps:
- Restructuring the code to differentiate the services into separate folders and the common dependent code into one.
- Creating pipelines for each of the services with the proper code component dependencies defined in the pipelines.
- Separating the GitLab repository for each service to provide ease of maintenance for their small engineering team.
- Assisting you in developing new export microservices as per the requirement.
- Ensuring the proper usage of serverless and EKS with the right configuration for some services running in JRE in a docker container ensures zero downtime upgrade.
- Providing the proper README and other details makes it easy for the customer to maintain all the services well in this structure.
To help our readers better understand the solution, here is the graphical presentation of our DevOps pipeline for serverless microservices and zero downtime upgrades.
