Introduction to Microservices

What is a Microservices?

Microservices are small, self-contained services that operate together to form a larger application, each with a specific business characteristic and the flexibility to be deployed separately. Microservices break down complicated programs into independent, loosely connected services, allowing for faster development, simpler scalability, and higher resilience.

Key Aspects of Microservices

• Small and independent
• Collaboration
• Business-driven
• Independent deployment
• Focused
• Flexible

Microservices Principles

• Modeled around the business domain
• Culture of Automation
• Hide implementation details
• Decentralization
• Deploy Independently
• Failure Isolation
• Highly Observable

When to use Microservices

Microservices succeed in large, complicated applications that require regular updates, flexible scaling, diverse domains, & small, agile development teams.

Advantages of Microservices

Advantages of Microservices include:

• Language and Framework Freedom
• Independent Development and Deployment
• Instantaneous scaling
• Fault Tolerance
• Upgrades are seamless
• Global Distribution with CI/CD Harmony

Challenges of Microservices

The following are the Challenges of Microservices:

• Complexity 
• Development and testing
• Lack of governance
• Network congestion and latency
• Data Integrity
• Management
• Versioning
• Skillset
