Module 1: Foundations of Cloud Architecture
- Core Definitions: Transitioning from on-premise infrastructure to elastic public cloud ecosystems.
- Service Delivery Models: Deep analysis of Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
- Deployment Topologies: Navigating architectural trade-offs between Public, Private, Hybrid, and Multi-Cloud environments.
- Cloud Economics: Shifting from Capital Expenditure (CapEx) to Operational Expenditure (OpEx) utilizing pay-as-you-go billing frameworks.
Module 2: Cloud Virtualization & Infrastructure
- Hypervisor Engineering: The technical mechanics behind hardware virtualization, Type-1 vs. Type-2 hypervisors, and multi-tenancy arrays.
- Global Infrastructure Networks: Mapping cloud footprints across Availability Zones (AZs), geographic Regions, and Edge Locations.
- Elastic Compute Provisioning: Spin-up operations for Virtual Machines (AWS EC2 / Azure VMs) and configuring CPU/RAM hardware configurations.
- Serverless Footprints: Executing code directly via event-driven compute services (AWS Lambda / Azure Functions).
Module 3: Virtual Networking & Security Isolation
- Network Partitioning: Building secure software-defined networks (AWS VPC / Azure VNet) with isolated public and private subnets.
- Access Management Control: Writing granular firewall configurations utilizing Network Access Control Lists (NACLs) and Security Groups.
- Routing Architecture: Provisioning Internet Gateways, NAT Gateways, custom routing matrices, and Cloudfront CDN delivery endpoints.
- Applied Lab: Deploying a multi-tier web application within a completely isolated, secure custom network architecture.
Module 4: Cloud Storage Systems & Database Architecture
- Object Storage Networks: Storing unstructured enterprise file trees inside highly durable platforms (AWS S3 / Azure Blob Storage).
- Block and File Storage: Mounting persistent block storage drives (AWS EBS) and networked file shares to cloud server systems.
- Relational Cloud Databases: Provisioning and clustering highly available SQL structures utilizing fully managed platforms (AWS RDS / Azure SQL).
- NoSQL Implementations: Architectural scaling patterns for ultra-low latency document databases (AWS DynamoDB / Azure Cosmos DB).
Module 5: Identity and Access Management (IAM)
- The Principle of Least Privilege: Structuring rigid access rules to restrict cloud resource interactions uniformly.
- Policy Configuration: Writing custom JSON access policies, managing root configurations, and enforcing Multi-Factor Authentication (MFA).
- Federated Identity: Integrating corporate Single Sign-On (SSO) frameworks with cloud providers utilizing Active Directory tokens.
- Shared Responsibility Model: Demarcating explicit operational security boundaries between the cloud vendor and the enterprise user.
Module 6: High Availability, Auto-Scaling & Load Balancing
- Traffic Distribution: Configuring Application Load Balancers to distribute concurrent incoming user queries across multiple target pools.
- Horizontal Auto-Scaling: Creating policy rules that monitor hardware stress thresholds and automatically provision new servers to maintain uptime.
- Disaster Recovery (DR): Implementing backup matrices across Backup, Pilot Light, Warm Standby, and Multi-Site active failovers.
- Applied Lab: Stress-testing an active system to watch an auto-scaling group automatically double compute instances under fire.
Module 7: Cost Optimization, Governance & Cloud Management
- FinOps Practices: Budget tracking, setting up billing threshold alarms, and cleaning up orphaned volumes to eliminate overhead.
- Telemetry Logging: Configuring provider audit trails (AWS CloudTrail / Azure Monitor) to track and index all API operations.
- Compliance Auditing: Utilizing cloud advisor engines to check active infrastructure setups against global security frameworks.
- Well-Architected Framework: Designing systems aligned with the 5 core pillars: Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization.
