Intro cloud och edge
What are the characteristics of cloud computing?
- Service-Based IT-resources
- On-Demand Self-Service
- Ubiquitous Access
- Multitenancy
- Location independence
- Rapid Elasticity
- Pay-per-use Billing
Explain the characteristic Service-Based IT-resouces
Cloud resources can be accessed or provisioned without human interaction. With this model, consumers can gain immediate access to cloud services upon signup
Explain the characteristic On-Demand Self-Service
Cloud services are on-demand; that is, service users can request services independently and almost immediately depending on their requirements, without interacting with the service provider
Explain the characteristic Ubiquitous Access
Cloud services are provided via a broadband network, mostly using the Internet. Consequently, cloud customers can access any cloud service from any platform or device at any time
Explain the characteristic Multitenancy
Multitenancy is the ability to have multiple customers use the shared resources
Explain the characteristic Location Independence
When using cloud services, the cloud customer generally has no control over or knowledge of where the provided resources are actually located
Explain the characteristic Rapid Elasticity
Provisioned cloud resources can be adapted and shared more flexibly, in some cases fully automatically, in order to match the resources to the current needs
Explain the characteristic Pay-Per-Use Billing
Cloud customers are charged for the amount of time they actually use the resource or related measures.
What’s a cloud customer?
A person or organization that maintains a business relationship with and uses the service a Cloud provider offers
What’s a Cloud provider?
A legal person or organization responsible for making a
cloud service available to interested parties
What are Cloud Data Centre Operators?
They provide the IT infrastructure (server rooms, power supply blablabla)
What are cloud auditors?
They perform independent assessments to determine whether a cloud service fulfills given requirements
What are cloud brokers?
They manage the use, performance and delivery of cloud services. They also negotiates the relationships between cloud providers and cloud customers. They provide service in 3 categories:
- Service Intermediation
- Service Aggregation
- Service Arbitrage
What are the 3 Cloud service models?
-Infrastructure as a Service
-Platform as a Service
-Software as a Service
What are the four deployment models?
- Private: Used by single organization and its members
- Public: Distribute cloud across multiple organizations
- Community: Exclusively by specific community. Used by The community members, third party of combo of both
- Hybrid: Consists of two or more of the above mentioned models
What’s the difference between Outsourcing and Cloud Computing?
Cloud computing is an evolution and a specific form of IT outsourcing. Thus, it shares common characteristics and provides similar benefits to customers. ??????
What’s Decoupling when talking about Transformative Mechanisms?
When one element of a system becomes an independent service with service interface so internal changes in the service will effect other elements
What’s Platformization when talking about Transformative Mechanisms?
When an entity creates access and interaction points around services within an ecosystem
What’s Recombination when talking about Transformative Mechanisms?
Generating innovation potential by combining cloud services and integrating them with other transformative technologies
What are some Risks and challenges with cloud computing?
- Multi-tenancy
- Loss of Control
- Location Transparency
- Lack of Availability
- Compromised Ease of Use
- Vendor Lock-In
- Limited Service Continuity
What are some challenges regarding SECURITY and PRIVACY of cloud computing?
- Communication Issues
- Data Breaches
- Data Loss
- Data Scavenging
- Insufficient Identity, Credentials, and Access Management
- Insecure Interfaces and APIs
- System Vulnerabilities
- Shared Technology Vulnerabilities
What are the differences between Cloud- and Edge-computing?
The services in Edge are located in the Edge network whereas the services in Cloud are located within the internet.
Cloud has high latency due to longer distance.
Cloud has higher jitter
Edge is location-aware and supports mobility
Edge uses distributed servers and Cloud uses centralized
Target users for Cloud are “regular” internet users and for edge it is service subscribers.
Edge hardware is less scalable due to hardware limitations
What’s fog computing?
Subset of edge computing, introduces hierarchical structure which extends clouds capabilities into the edge of the network.
ENABLES localized processing
What is Mobile Edge Computing?
It’s a form of edge computing for mobile network where the computing resources are deployed typically at the base stations or cell towers. This allows low-latency processing and improved performance.
What is application service provision and how does it compare to cloud computing?
Application Service Provision is a form of outsourcing where firms rent packaged software from a third party. In cloud computing, SaaS is the closest corresponding
What’s the vision of Grid Computing?
To reduce costs, increase reliability and flexibility
Data centre technologies is one of 3 cloud technologies, what are the other two?
Virtualization Techniques
Multi-tenant techniques
What is the “The process where one entity creates access and interaction points around code bundle of services within eco-systems of customers, complementors and stakeholders”
Platformization (Transformative technology)
What is “The process where innovation potential is generated by combining cloud services and integrating them with other transformative technologies within platform ecosystems”
Recombination (Transformative technology)
