Cloud Computing Flashcards
What are the two traditional IT Deployment Models?
On Prem and Colo (Co-Location)
What do these characteristics represent in an IT Deployment Model?
- All equipment is located in your building
- All equipment is owned by you
- There are clear lines of demarcation - everything in the building is your responsibility, the connections between offices are your network service providers responsibility
- Equipment is CapEx
- New equipment will typically take over a week to deploy
- Equipment requires technology refreshes
- You need to consider redundancy
On Premises
What does these characteristics represent in an IT Deployment Model?
- The facility owner provides power, cooling and physical security for their customer’s server, storage and network equipment
- Your user desktops will still be in your offices
Co-Location
_________________is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction
Cloud Computing
What characteristic is this pertaining to Cloud Computing?
A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with with each service provider
On-Demand Self Service
What characteristic is this pertaining to Cloud Computing?
Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time
Rapid Elasticity
What characteristic is this pertaining to Cloud Computing?
Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogenous thin or thick client platforms such as mobile phones, tablets, laptops and workstations
Broad Network Access
What characteristic is this pertaining to Cloud Computing?
The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant channel model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand
Resource Pooling
What characteristic is this pertaining to Cloud Computing?
Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service such as storage, processing, bandwidth, and active user accounts
Measured Service
This allows for resource pooling where multiple customers share the underlying hardware
Server Virtualization
Type ____ Hypervisors run directly on the system hardware
1
Type _____ Hypervisors run on top of a host operating system
2
_____________ supports combining multiple physical systems into a single virtual system
Clustering
__________ supports running multiple virtual systems on a single physical system
Virtualization
What are the 8 pillars of the Data Center stack?
- Data
- Applications
- VM OS
- Hypervisor
- Compute Hardware
- Storage
- Network Hardware
- Facility
What are On Prem customers responsible for in regards to the Data Center stack?
All 8 pillars
What are Co-Location customers responsible for in regards to the Data Center Stack?
All infrastructure hardware. The provider manages the facility and the incoming network connections. That’s mainly it.
What Service does this describe?
- Provider is responsible for Hypervisor, Compute, Storage, Network and Facility
- Customer is responsible for Operating System (VMs), Applications and Data
IaaS (Infrastructure as a Service)
What Service does this describe?
- Provider is responsible for Operating System (VMs), Hypervisor, Compute, Storage, Network, Facility
- Customer is responsible for Applications and Data
Paas (Platform as a Service)
What Service does this describe?
- Provider manages everything in the data center stack
- An example of SaaS would be Microsoft 365, Salesforce, etc.
- Customer gets access at the Application level with SaaS
SaaS (Software as a Service)
What are the four Cloud Deployment Models?
- Public Cloud
- Private Cloud
- Community Cloud
- Hybrid Cloud
What fits this definition?
The Cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider.
Public Cloud
What fits this definition?
The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises
Private Cloud
What fits this definition?
The Cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (mission, security requirements, policy, and compliance considerations)
Community Cloud
What fits this definition?
The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (eg, cloud bursting for load balancing between clouds)
Hybrid Cloud
Companies with limited Private Cloud infrastructure may _____________ into Public Cloud for additional capacity when required
Cloud Burst
What are advantages of Cloud Computing?
- Scalability
- Business Agility
- Cost Efficiency
- Competitive Advantage
- Productivity
- Availability and Reliability
- Cost
