What server architectures support microservices?
Server architectures that support microservices are designed to run many small, independent services that communicate with each other through APIs. These architectures focus on scalability, fault isolation, and independent deployment. Here are the main types used today:
This is one of the most common architectures for microservices.
How it works
Each microservice runs inside a container.
Containers package the application and its dependencies.
Services can run independently and scale separately.
Key technologies
Docker – packages applications into containers
Kubernetes – manages and scales containers across servers
Advantages
Easy deployment
Consistent environments
Fast scaling
Example use
Large SaaS platforms and modern web applications.
Cloud platforms provide infrastructure specifically designed for microservices.
How it works
Applications run on distributed cloud infrastructure.
Services communicate through APIs and managed networking.
Common platforms
Amazon Web Services
Google Cloud Platform
Microsoft Azure
Advantages
Auto-scaling
Global deployment
Managed infrastructure
In serverless systems, developers focus only on functions while the platform manages servers.
How it works
Microservices are implemented as event-driven functions.
The cloud provider automatically runs and scales them.
Example services
AWS Lambda
Azure Functions
Google Cloud Functions
Advantages
No server management
Automatic scaling
Pay-per-use pricing
Service mesh manages communication between microservices.
How it works
A network layer handles service discovery, traffic routing, and security.
Each service runs with a sidecar proxy.
Popular technologies
Istio
Linkerd
Advantages
Secure service communication
Traffic management
Observability
An API gateway acts as the entry point for all microservices.
How it works
Clients send requests to the gateway.
The gateway routes requests to the appropriate microservice.
Common tools
Kong
NGINX
Advantages
Simplifies client access
Centralized authentication
Load balancing
💡 Typical modern microservice stack
A common architecture looks like this:
Client → API Gateway → Containers → Orchestrator → Microservices → Databases
Technologies often used together:
Docker
Kubernetes
Istio
NGINX
✅ Summary
Microservices are best supported by architectures that provide:
Containerization
Distributed cloud infrastructure
Automated orchestration
API-based communication
Independent scaling
