Power
Cooling
Network Connectivity
In cloud computing, cloud providers typically take on the following in the shared responsibility model (4)
Data and Information
Access Security
In cloud computing, consumers typically take on the following in the shared responsibility model (2)
Everything
What are on-site data centers responsible for?
Infrastructure as a Service
Platform as a Service
Software as a Service
The Shared Responsibility Model is heavily tied to cloud service types, such as (3)
Infrastructure as a Service
Places the most responsibility on the consumer where the cloud provider is only responsible for the basics of physical security, power, and connectivity
Platform as a Service
Evenly distributes responsibility between the cloud provider and the consumer
Software as a Service
Places most of the responsibility with the cloud provider
Information and Data
Devices
Accounts and identities
When using a cloud provider, you’ll always be responsible for (3):
Physical Data Center
Physical Network
Physical hosts
The cloud provider is always responsible for (3):
OS
Network controls
Applications
Identity and Infrastructure
Your service model will determine responsibility for things like (4):
Cloud models
Defines the deployment type of cloud resources
Private
Public
Hybrid
What are the three types of cloud models?
Private cloud model
Provides much greater control for the company and its IT department, may be hosted from onsite, offsite, or third party data centers, and comes at a greater cost than other models
Public cloud model
Built, controlled, and maintained by a third party cloud provider where anyone that wants to purchase cloud services can access and use resources. There is general public availability
Hybrid Cloud Model
Uses both public and private clouds in an inter-connected environment. It can be used to allow a private cloud to surge for increased, temporary demand by deploying public cloud resources and can be used to provide an extra layer of security
No capital expenditures to scale up
Applications can be quickly provisioned and deprovisioned
Organizations pay only for what they use
Organizations don’t have complete control over resources and security
Characteristics of Public cloud: (4)
Organizations have complete control over resources and security
Data is not collocated with other organizations’ data
Hardware must be purchased for startup and maintenance
Organizations are responsible for hardware maintenance and updates
Characteristics of Private Cloud: (4)
Provides the most flexibility
Organizations determine where to run their applications
Organizations control security, compliance, or legal requirements
Characteristics of Hybrid cloud (3)
Capital Expenditure (CapEx)
Operational Expenditure (OpEx)
When comparing IT infrastructure models, there are two types of expenses to consider
Capital Expenditure
Typically a one time, up front expenditure to purchase or secure tangible resources
Operational Expenditure
Spending money on services or products over time with no upfront costs that is consumption based.
Cloud computing is consumption based
Why does cloud computing fall under OpEx?
No upfront costs
No need to purchase and manage infrastructure
Pay for what you need
Stop paying for what you don’t need
Benefits of the Consumption based model (4)
You must estimate the future resource needs
Can be costly if you overestimate
Can lead to decreased performance if you underestimate
Can take a while to upgrade equipment to meet demand
Cons of using traditional datacenters (4)
pay-as-you-go pricing
Cloud computing is the delivery of computing services over the internet by using a ___ model.
Plan and manage your operating costs.
Run your infrastructure more efficiently.
Scale as your business needs change.
You typically pay only for the cloud services you use, which helps you (3):
