Concepts Flashcards
Economies of scale
-Allows for reduced costs buy operating at a larger scale
-pay for what you use
-global
Benefits of global infrastructure
-Quickly deploy applications globally
-increases global reach
-decreased redundancy and increased reliability
high availability
-Ensures applications are always accessible
-achieved through multiple data centers across multiple regions
-protects against failure
elasticity
-Automatically scale resources up/down based on demand
agility
-Quick development and deployment of applications
-wide range of services
AWS well architected frame work
Set of best practices and guidelines designed to help architects based on 5 pillars
-operational excellence
-reliability
-security
-performance efficiency
-cost optimization
Operational excellence (well architected frame work)
-Focus on operations in the cloud
-run, manage, and monitor production to deliver business value
reliability (well architected frame work)
- designing systems that can recover from failure/disruptions
-ensure everything is running the way it is intended to
-acquire computing resources to meet demand
security (well architected frame work)
-Ensures protection against unauthorized access and breachs
Performance efficiency (well architected frame work)
-Use compute resources efficiently to support demand changes while maintaining high performance
cost optimization (well architected frame work)
-Avoid and eliminate unneeded costs
-maximize value of cloud investments

-operations
Business perspective (CAF)
-Focus on aligning adoption with business goals
people perspective (CAF)
-Addresses human aspect of cloud
-emphasizes need for training on employees to prepare them
governance perspective (CAF)
-Establishing policies and compliance requirements for cloud usage to align it with policies
Platform perspective (CAF)
-Technical aspect of cloud adoption such as migrating on-premise workloads to the cloud
security perspective (CAF)
-Focus on protecting data/apps in the cloud
Operations perspective (CAF)
-Operational processes and practices for managing cloud resources effectively in the cloud
