Design - Infrastructure

System Components

Describe the infrastructural components needed:

Component Type Purpose Count
[Component 1] Server/Client/Service [Purpose] [Number]
[Component 2] Database/Cache [Purpose] [Number]

Component Types Reference

  • Clients - User-facing interfaces
  • Servers - Backend services processing requests
  • Load Balancers - Distributing traffic
  • Caches - In-memory data stores
  • Databases - Persistent data storage
  • Message Brokers - Asynchronous messaging systems
  • Queues - Task/message queuing
  • Workers - Background task processors
  • Proxies - Request routing and transformation
  • Firewalls - Network security
  • CDNs - Content delivery networks
  • Other - [Specify]

Component Distribution

Physical Distribution

Describe how components distribute across the network:

┌─────────────────────────────────────────┐
│ User's Machine / Browser                │
│ ┌─────────────────────────────────────┐ │
│ │ Client Application                  │ │
│ └─────────────────────────────────────┘ │
└────────────┬────────────────────────────┘
             │ Internet
             │
    ┌────────┴─────────┐
    │                  │
┌───▼───┐          ┌───▼───┐
│ Serv. │          │ Serv. │
│  DC1  │          │  DC2  │
└───┬───┘          └───┬───┘
    │                  │
    │   ┌─────────┐    │
    └──▶│Database │◀───┘
       └─────────┘

Distribution Strategy:

  • Geographically distributed - Components in different datacenters/regions
  • Same datacenter - Components co-located
  • Same machine - Components on single server
  • Hybrid - Mix of approaches

Service Discovery

How Components Find Each Other

Describe the mechanism for service discovery:

  • DNS - Traditional domain name resolution
  • Service Discovery - Dynamic service registry (e.g., Consul, Eureka)
  • Load Balancing - Through dedicated load balancers
  • Hardcoded Addresses - Static configuration
  • Other - [Specify]

Naming Convention

Define how components are named:

  • URL/Hostname: [service-name].[domain]:[port]
  • IP Address: [static-ip]
  • Service ID: [service-identifier]
  • Other: [Specify naming scheme]

Registration and Discovery Process

Describe the process:

  1. Component starts and registers with service registry
  2. [Additional steps...]
  3. Other components query registry to find services
sequenceDiagram
    participant Service as New Service
    participant Registry as Service Registry
    participant Client as Client Service

    Service->>Registry: Register(service_name, address, port)
    Client->>Registry: Query(service_name)
    Registry->>Client: Return(address, port)
    Client->>Service: Request

Deployment Environments

Define different deployment environments:

Development

  • Components: [Components in dev environment]
  • Location: [Where development runs]
  • Purpose: [Development, testing, debugging]

Staging

  • Components: [Components in staging]
  • Location: [Where staging runs]
  • Purpose: [Pre-production testing]

Production

  • Components: [Components in production]
  • Location: [Where production runs]
  • Purpose: [Live user-facing system]
