Cloud Computing Flashcards
What are Advantages of Cloud Computing?
- Trade Upfront expense for variable expense.
- Benefit from massive economies of scale.
- Stop guessing capacity.
- Increase speed & agility
- Stop spending money running & maintaining data centers.
- Go global in minutes.
How does the scale of cloud computing help you save costs?
Aggregated cloud usage from a large number of customers results in lower pay-as-you-go prices.
Not having to invest in technology resources before using them relates to what?
Trade upfront expenses for variable costs.
Accessing services on-demand to prevent excess or limited capacity relates to what?
Stop guessing capacity
Quickly deploying applications to customers & providing them with low latency relates to what?
Go global in minutes
Three deployment models of AWS Cloud
- Cloud
- Hybrid
- On-Premises
Benefits of Cloud Computing
- Trade upfront expense for variable expense
- Stop spending money to run & maintain data centers
- Stop guessing capacity
- Benefit from massive economies of scale
- Increase speed & agility
- Go global in minutes
Upfront Expense
Data centers, physical servers, & other resources that you would need to invest before investing in them.
Variable Expense
Only pay for computing resources that you consume instead of data centers & servers before you use them.
Benefit of variable expense
Companies can implement innovative solutions while saving on costs
Focus less on managing infrastructure and servers relates to what?
Stop spending money to run & maintain data centers.
What is “Trade upfront expense for variable expense” Cloud Computing Advantage?
Pay only when you consume computing resources & not have to worry about upfront expenses s/a data centers, physical servers, etc . . .
What is “Benefit from massive economies of scale” Cloud Computing Advantage?
Getting lower variable cost b/c of many AWS customers means lower pay as you cost.
What is “Stop guessing capacity.” Cloud Computing Advantage?
Don’t have to predict infrastructure capacity needed before deploying application & by only paying/using resources that you need.
What is “Increase Speed & Agility” Cloud Computing Advantage?
Makes it easier to develop/deploy applications & allows you more time to experiment & innovate.
What is “Stop spending money running and maintaining data centers.” Cloud Computing Advantage?
Ability to focus less on managing infrastructure & more on your applications & customers.
What is “Go global in minutes.” Cloud Computing Advantage?
Allows you to deploy applications quickly & with low latency due to AWS Cloud global footprint.
