Infrastructure Deployment Models

Deployment Topologies

Deployment Type Characteristics Key Considerations

Single-Node

Minimal resource footprint

Development, small-scale testing

Clustered

Multiple nodes, distributed processing

Production, high availability

Hybrid

Mix of on-premises and cloud resources

Flexible scaling, cost optimization

Edge-Optimized

Lightweight, resource-constrained environments

IoT, remote locations

Resource Management

Resource Allocation Strategies

Compute Resources

  • CPU allocation models

  • Memory management

  • Performance optimization techniques

Storage Provisioning

  • Storage class definitions

  • Dynamic vs. static provisioning

  • Performance and capacity planning

Network Configuration

  • Network overlay models

  • Multi-network support

  • Network policy implementation

Infrastructure as Code (IaC)

Core IaC Principles

Principle Description

Declarative Configuration

Define desired infrastructure state explicitly

Version Control

Treat infrastructure configurations like software code

Immutability

Create new infrastructure instead of modifying existing

Automated Validation

Implement continuous validation and testing

IaC Tools and Frameworks

  • Terraform

  • Ansible

  • CloudFormation

  • Custom orchestration tools

Scaling Strategies

Horizontal Scaling

  • Dynamic node addition

  • Automatic resource allocation

  • Load distribution mechanisms

Vertical Scaling

  • Resource allocation adjustments

  • Performance tuning

  • Capacity planning

Monitoring and Observability

Monitoring Components

Monitoring Aspect Key Metrics

Performance

CPU utilization, memory consumption, network throughput

Health

Service availability, error rates, response times

Resource Utilization

Capacity planning, workload distribution

Compliance

Security configurations, policy adherence

Observability Tools

  • Prometheus

  • Grafana

  • ELK Stack

  • Native monitoring solutions

Hands-on Exercise: Infrastructure Provisioning

Exercise Objectives

  • Demonstrate infrastructure deployment

  • Practice IaC techniques

  • Implement scaling configuration

# Example infrastructure provisioning command
{infractl} deploy --config infrastructure.yaml \
    --scale-mode automatic \
    --monitoring-level comprehensive
