Azure Fundamentals Flashcards
Define Cloud Computing, with examples…
The delivery of computing services over the internet. Such as web hosting, databases, BaaS, storage, VMs etc.
Why are cloud solutions scalable?
They are not constrained by hardware, and scale horizontally.
What are the 4 types of cloud environments?
Public - Open for public use.
Private - Used by one organisation.
Hybrid - Users can be bother public and private.
Multi-cloud - Users use 2 or more public clouds at one time.
What is Azure Arc?
Microsoft’s cloud management solution, where you can manage your cloud environments in 1 place.
What is Azure VMWare Solution?
Enables you to run external cloud workloads in your Azure environment.
When setting up new IT Infrastructure, what are the 2 types of expenditure?
Capital Expenditure - Initial, one time cost to get up and running. I.e. server installation, building work etc.
Operational Expenditure - Day to day cost. E.g. Cloud computing resources you are using per day.
What type of IT Infrastructure expenditure is Cloud Computing?
Operational Expenditure.
In which document are availability guarantees stated?
SLA.
What uptime does Azure guarantee?
99%
What types of scaling does Azure (and cloud computing in general) demonstrate?
Vertical and Horizontal.
Describe Vertical Scaling in Cloud Computing…
Increases the service of a cloud resource. E.g. add more CPUs to a VM, thereby increasing the processing power of a single compute resource.
Describe Horizontal Scaling in Cloud Computing…
Increase the number of cloud resources or services available. E.g. make more VM;s accessible for use.
What are the 4 main benefits of Cloud Computing services?
Accessibility
Scalability
Reliability
Predictability
What makes Cloud Computing architecture reliable?
Distributed system mitigates against single point of failure.
What makes Cloud Computing predictable?
Consumption based model means you only pay for what you use.
