 Infrastructure as a Service (IaaS)

• Outsourcing the infrastructure of a Network
• Infrastructure in maintained on the internet or by third party companies

Platform as a Service (PaaS)

• Allows a company to have application deployment
• Tools and programming languages available to the customer via the cloud from a 3rd party
• Development Tools

Software as a Service (SaaS)

• On-demand software applications
• Can access from a thin client over the Internet
• Web browser based items, Gmail is an example of SaaS

Database as a Server (DBaaS)

• Cloud providers offer database functionality to the consumers

Communication as a Service (CaaS)

• Communication services leased to the consumer from the provider
• Examples of CaaS
  • VPN, VoIP, PBX (Skype, etc.)

Business Process as a Service (BPaaS)

• Business Service delivered utilizing the cloud
• Combines bus. proc. mgt. (BPM) with 1 or more aspects of a cloud deployment model
  • Business process are uploaded to a cloud service for processing and monitoring

Anything as a Service (XaaS)

• Works in combination with SaaS, IaaS, PaaS, CaaS, DBaaS, or BPaaS
• X is the variable that is interchangeable and represents different cloud services.

Accountability and Responsibility by Service Model

• Who does the model apply to?
  • SaaS – End Users
  • PaaS – Developers
  • IaaS – Administrator

Who is responsible?

• SaaS – Provider
• PaaS – Consumer
• IaaS – Consumer

 Cloud Delivery Models and ServicesPrivate CloudPrivate cloud is similar to the IntranetProtected by a firewall and unaccessible to the publicPublic Cloud

• Leased from a cloud provider to the customer
• Pool of resources that a provider will lease
  • Can offer a Pay as you go

Hybrid Cloud

• Uses a combination of private and public cloud

Community Cloud

• Infrastructure shared with several organizations

On-Premise

• Traditional data center management
• Virtualized servers hosting on-site
• Organization has complete control over its servers
• Organization is responsible for costs of the data center

Off-Premise

• Referred to as cloud computing
• Hosting in the cloud and accessed online
• Cloud provider owns the hardware
• Cloud provider has some control over the servers
• Reduces costs, as cloud provider is responsible for the data center

Orchestration Platforms

• For day-to-day tasks
• Automated management of cloud environments
• Syncs business requests with infrastructure

 Cloud Characteristics and TermsElasticity

• Enables computing resources to be moved as needed
• Shifts resources across the infrastructure
  • Allows workload to be increased to additional hardware inside a pool

Demand-Driven Service

• Customers use an online portal to access the services
• A supplier can provide provision cloud resources on demand

Pay-as-you-Grow

• Pay for the services as needed
• Pay for the computing resources that are being used
• Pay for services by time, hour, or data.

Chargeback

• Accounting strategy to decentralize IT costs
• Charge the department independently for the services that are being used
• Services are billed to the department’s budget versus the IT’s budget
• Also known as showback

Ubiquitous Access

• Same level of access from anyplace
• Able to access the resources with the same ability from any location

Metering

• Tracking of IT resources
• Measure usage by cloud consumer
• Allows the consumer to be charged for the resources used

Multitenancy

• Allows one instance to many users
• Each user has a view of the application
• Users are oblivious to other users

Cloud Bursting

• Allows retail to explode to the cloud when resources are scarce
  • The resources are in the local LAN, when the local LAN is overused the resources become available in the cloud.

 Object Storage ConceptsObject IDUnique identifiers for the data and metadataUsed to find the dataMetadata

• Describes each object in the database
• Used like a table for a database
• Contains the compounds of the data

Data BLOB

• Binary large object (BLOB)
• Primarily used in databases
• Large amounts of binary data stored in a location to help copy between location

Policies

• Attributes associated with objects
• Similar to metadata but for security mechanism

Replicas

• Copies of large data set
• Associated with VHD (virtual hard disk)
  • Require a copy mechanism
