Cloud Computing
- Services experience very little downtime when using the cloud
- ______ is the percentage of uptime versus downtime
High Availability
increase the number of items in a system at a linear rate or less
Scalability
increasing the power of the existing resources in the working environment such adding more RAM or CPU
Vertical Scaling (Scaling Up)
Adding additional resources to help handle the extra load being experienced such as another more servers
Horizontal Scaling (Scaling Out)
The ability to quickly scale up or down
Rapid Elasticity
- Being charged for a service on a pay per use basis
- the benefit of using the cloud is that most things are done on a metered basis
Metered Utilization
- Charging is based upon the actual usage of the service being consumed
Measured services
- The ability to minimize the costs by putting VMs on other servers
- _____ is pooling together all the hardware to make a cloud provider
Shared Resources
The ability to store data that can spread to other places depending on the configuration
File Synchronization
Systems and users interact with devices on public networks, such as the internet and other clouds
Public Cloud
Systems and users that only have access with other devices inside the same private cloud or system
Private Cloud
Combo of private and public clouds
Hybrid Cloud
Collaborative effort where infrastructure is shared between several organizations with common service needs
Community Cloud
Allows customers to share computing resources in a public or private cloud
Multitenancy
Assigns a particular resource to a single organization
Single tenancy
- Needs to procure hardware, software, and personnel necessary to run the organization’s cloud
On-Premise Solution
____ solution allows the ability to control all the physical and logical access to servers
On premise solution
Third party service provider that provides all the hardware and facilities needed to maintain a cloud solution
Hosted Solution
Hosts desktop OSs within a virtualized environment hosted by a centralized server or server farm
Virtual Desktop Infrastructure (VDI)
Data in _____ solution may be exposed to other servers
multitenancy
Maintained by a service provider and provided to the end user as a service
Hosted Model/ Desktop as a Service (DAAS)
Performs all the application processing and data storage
Sever
