Cloud Concepts Flashcards
How do I set up a budget?
Traditional data center disadvantages
Large up front cost, Forecasting demand is difficult slow to deploy dc and servers Maintaining is expensive Responsibility for security compliance
Advantages of Cloud Computing
Trade capital expense for variable expenses (pay for what you use)
Benefits from massive economies of scale
Stop guessing capacity
Increase speed and agility
Stop spending to maintain data centers
Go global in minutes
What is elasticity?
Ability to acquire resources as you need them and release them when you no longer need them, automatically
What is reliability?
Amazon’s infrastructure is built to maximize reliability for cloud workloads
Agility
Lower cost of trying new ideas or processes
Reduces time to maintain infrastructure
Reduce risk around security and compliance
Provides access to emerging technology (like block chain)
What is cloud computing?
On demand delivery of compute power, database storage, apps, and other IT resources through cloud service platform via internet with pay as you go pricing
Cloud Computing Models
Iaas - Infrastructure as a service (we maintain everything, from the OS version to the ports of servers) on the cloud
Sass - Everything is maintained for us, like Teams or Gmail
Cloud Deployment Models
Public Cloud - Deployed onto public cloud providers like AWS
On-Premises - Cloud-like platform in a private data center (VMWare)
Hybrid - Cloud applications connected to a private data center
AWS Global Infrastructure
AWS Regions
Edge Locations
AWS Global Infrastructure Visualization
AWS Regions
Each region is in a specific geographic location
A cluster of data centers in each region
AWS 22 Launches regions
Availability Zones
One or more data centers
Each region has at least 2 availability zones
Redundant power, networking, and connectivity
69 availability zones launch
Availability
Extent which an application is fulfilling its intended business purpose
High availaibility is for single failures won’t fail
us-east-2a
us - AREA
east - subarea
2a - number AZ
region name us-east-2
availiability zone us-east-2a
Edge Locations
CDN - Global Content Delivery Network
Amazon CloudFront and Route 53 (DNS Service) use edge locations
Wide area to fetch content from
AWS Global Infrastructure Visualization
Feature to show all of the regions, availability zones, and edge locations
CapEx
Capitalized Expenditure - Building servers, building, equipment, fixed asset etc.
OpEx
Operating Expenditures - Operating Expenses to maintain
Own Datacenter disadvantages
LArge upfront capex
underused capacity or unmet demand
increating capacity takes time and more capex
monthly costs will map to predicted infrastructure needs
Cloud infrastructure
No up-front investment
pay as you go, OpEx
Scale immediately
monthly costs maps to user demand
AWS Cost Explorer
Providers breakdowns by service, cost tag
Provides predictions for next three months
Recommendations for cost optimization
Accessed via API
AWS Budgets
Plan and track usage on AWS services using data from AWS Cost Explorer
AWS TCO Calculator
Total Cost of Ownership
- Moving workload from data center to cloud
- Download the report
AWS Simple Monthly Calculator (deprecated)

AWS Resource Tags
Metadata we attatched,
includes name and optional value
include deprarment, enviorment, or project
cost report by tags
AWS Organization
Consolidated billing between each AWS account in the organization
Security standards and centralized logging
AWS Cost Explorer
Current monthly cost, the forecasted month-end cost
Group by tag, service, linked accounts, etc.
