Foundations of Cloud Computing Flashcards
Cloud Computing Advantages
Global in Minutes
No Data Center Spend
Economies of Scale
Speed and Agility
Stop Guessing Capacity (Elastic)
Capex for Variable Expense
Cloud Computing Benefits
High Availability: Operate continuously
Elasticity: Provision what you need to grow and shrink on demand
Agility: Access to multiple services
Durability: Long term data protection
Cloud Computing Models
IaaS: Building blocks
SaaS: Programs for use
PaaS: develop tools without worry about underlying infrastructure
Cloud Deployment Models
Private Cloud: On-prem, internal data center, no cloud advantages
Public Cloud: No hardware responsibility, all advantages of cloud
Hybrid Cloud: Sensitive data is local, connect to cloud via VPN/Direct Connect
AWS Region
Physical location that under a geographic location (EX: Ohio/N. Virgina - US East)
Regions are fully independant of each other
Resources are not automatically replicated across regions
Made of of multiple AZs
AWS Availability Zones
AZs exist in Regions
AZs consist of one or more separate data centers
“One of more discrete data centers with redundant poser, networking, and connectivity in an AWS Region
All DCs connected via low latency links, fault tolerant, highly available
Local Zones
Place AWS services closer to end-users
Extensions of AWS Regions that provide high bandwidth and secure connection to Region
Edge Locations
Cache content for faster delivery to end-users
Do not house resources
Use the AWS backbone network
