- Global Design Considerations: Explore implications of regional availability, latency, and service variations for multi-region or global AWS deployments.
Requirements / Prerequisites
- Foundational Cloud Knowledge: A basic understanding of cloud computing principles and core AWS services like EC2, S3, and VPC.
- AWS Console Familiarity: Prior experience navigating the AWS Management Console is highly beneficial for contextual understanding.
- IT Infrastructure Basics: General knowledge of networking concepts, databases, and general IT system architecture.
- Architectural Improvement Drive: A strong desire to enhance and refine your skills in designing robust, scalable AWS solutions.
- No advanced programming skills are strictly required; a conceptual understanding of software systems is key.
Skills Covered / Tools Used
- Strategic Cloud Design: Developing a holistic approach to building AWS solutions that are cost-optimized, performant, and highly scalable.
- Critical Service Evaluation: Analyzing AWS service specifications, identifying implicit trade-offs, and challenging conventional design assumptions.
- Architectural Pattern Application: Effectively utilizing established patterns like microservices, event-driven, or serverless with appropriate AWS services.
- Cloud Cost Optimization: Applying rigorous methods to evaluate the Total Cost of Ownership (TCO) for diverse AWS service configurations.
- Risk Identification & Mitigation: Pinpointing and addressing potential architectural risks, including vendor lock-in, operational overhead, or security gaps.
- Decision Framework Mastery: Implementing structured decision matrices, comparative analysis tools, and architectural review processes for selection.
- Architectural Justification: Clearly documenting and defending AWS architectural choices to both technical and non-technical stakeholders.
- Cloud Governance Integration: Understanding how service selections impact organizational governance, resource tagging, and policy enforcement within AWS.
- Continuous Learning Strategies: Developing effective methods for staying current with the rapidly evolving AWS service landscape and new feature releases.
- Trade-off Analysis Expertise: Skillfully balancing various design dimensions (cost, performance, resilience, operational effort) in AWS architecture.
