There are numerous reasons why outsourced microservices projects fail. We shall discuss the key failure patterns (anti-patterns) that we have observed in industries:

1. Ineffective Architectural Governance

In the case of several vendors or remote teams working on the various services, they may have their conventions. In the absence of good architectural governance:

• APIs become inconsistent.
• Data contracts are prone to breaking.
• Service discovery and communication is no longer reliable.

Solution:

• Establish explicit architecture blueprints, governance policies, and versioning policies at the outset. Create a Central Architecture Board that will review all services prior to deployment.
  
  

2. Lack of DevOps Maturity

DevOps-free microservices is anarchy. CI/CD pipelines are essential to provide fast updates and stable rollouts.

Solution:

• Use powerful CI/CD pipelines (Azure DevOps, Jenkins, GitHub Actions).
• Provisioning of environments with Infrastructure as Code (IaC).
• Rollout with blue-green or canary deployments.

In Niotechone, DevOps pipelines are incorporated in all ASP.NET Core development projects in Rajkot and Azure cloud application development projects to ensure that downtime is minimal and the velocity is high.

3. Excessively Complicating the Early Stages

Most teams leap directly into using microservices on small projects that do not require them. This causes unwarranted complexity.

Solution:

• Begin with small steps — first split high-value modules. The system is gradually scaled with containerization and orchestration with Docker or Kubernetes as the system grows.
  
  

4. Poor API Management and Documentation

In cases where two or more microservices interact, documentation issues may lead to API mismatch, which will lead to broken features.

Solution:

• Standardize API formats (OpenAPI/Swagger).
• Apply API gateways such as Azure API Management or Kong.
• Keep appropriate API lifecycle records.
