Module 1 Flashcards
Define cloud computing (4)
- delivery of computing services over the internet
- include common IT infrastructure such as virtual machines, storage, databases, and networking
- expand the traditional IT offerings to include things like Internet of Things (IoT), machine learning (ML), and artificial intelligence (AI).
- , it doesn’t have to be constrained by physical infrastructure the same way that a traditional datacenter is
Describe the shared responsibility model (2)
-a security and compliance framework that outlines the responsibilities of cloud service providers (CSPs)
-customers for securing every aspect of the cloud environment, including hardware, infrastructure, endpoints, data, configurations, settings
shared-responsiblity model
Name what the customer will always be responsible for
-The information and data stored in the cloud
-Devices that are allowed to connect to your cloud (cell phones, computers, and so on)
-The accounts and identities of the people, services, and devices within your organization
shared-responsibility model
What is the service model responsible for: (4)
ONAI
-Operating systems
-Network controls
-Applications
-Identity and infrastructure
shared-responsibility model
The cloud provider is always responsible for:
3P’s
The cloud provider is always responsible for:
The physical datacenter
The physical network
The physical hosts
Define Cloud models
Hybrid cloud
Hybrid cloud
- a computing environment that uses both public and private clouds in an inter-connected environment
- used to allow a private cloud to surge for increased, temporary demand by deploying public cloud resources.
- used to provide an extra layer of security. For example, users can flexibly choose which services to keep in public cloud and which to deploy to their private cloud infrastructure.
Define Cloud models
Private cloud (4)
-It’s a cloud (delivering IT services over the internet) that’s used by a single entity.
- provides much greater control for the company and its IT department.
- comes with greater cost and fewer of the benefits of a public cloud deployment.
- may be hosted from your on site datacenter. It may also be hosted in a dedicated datacenter offsite, potentially even by a third party that has dedicated that datacenter to your company.
Define Cloud models
Public cloud
-built, controlled, and maintained by a third-party cloud provider.
-With a public cloud, anyone that wants to purchase cloud services can access and use resources.
-The general public availability is a key difference between public and private clouds.
Define Cloud models
compare all 3
public - Applications can be quickly provisioned and deprovisioned
private - Data is not collocated with other organizations’ data
hybrid - Organizations determine where to run their applications
consumption model
Describe the consumption-based model
-you don’t pay for the physical infrastructure, the electricity, the security, or anything else associated with maintaining a datacenter.
- you pay for the IT resources you use. If you don’t use any IT resources this month, you don’t pay for any IT resources.
consumption model
Benefits of consumption-based model
-No upfront costs.
-No need to purchase and manage costly infrastructure that users might not use to its fullest potential.
-The ability to pay for more resources when they’re needed.
-The ability to stop paying for resources that are no longer needed.
Consumption model
What does paying only for the cloud services you use help :
-Plan and manage your operating costs.
-Run your infrastructure more efficiently.
-Scale as your business needs change.
