Cloud Computing Flashcards
What is the customer responsible for under the Shared Responsibility Model in cloud computing?
-What they store in the cloud while using the service
-What devices they connect to the cloud provided by the service
-The accounts and IDs for all entities granted access to your cloud
What is the service provider responsible for under the Shared Responsibility Model in cloud computing?
-The physical state of THEIR hardware and software (operating system software, machines, and the network of those machines) that is used for the cloud services
What is notable about Infrastructure-As-A-Service (IaaS) in cloud computing?
In IaaS, the service consists of only the service provider’s machines and the network between the machines.
What is notable about Platform-As-A-Service (PaaS) in cloud computing?
In PaaS, the service consists of the service provider’s machines, network, plus the service provider’s software, which usually includes their operating system. However, both the customer and the service provider can make choices based around which network settings, software applications, methods of entity identity and directory logistics are used within their relative cloud.
What is notable about Software-As-A-Service (SaaS) in cloud computing?
In SaaS, the service is similar to that of PaaS (total hardware and operating system responsibilities to the provider), but, unlike the former, the service provider also assumes complete responsibility over network settings as well as which applications are used, while responsibilities around methods of identity and directory logistics remain shared between the customer and the service provider.
Describe a private cloud service.
A private cloud service is a cloud-based service and infrastructure that is owned, used and maintained by the same entity, whether it is an individual or group.
Describe a public cloud service.
A public cloud service is a cloud-based service and infrastructure that is owned and maintained by a service provider, whether it is an individual or group, and outside individuals or groups are allotted access to the service in return for a lump sum or an agreement to momentary payments (most commonly).
Describe a hybrid cloud service.
A hybrid cloud service is a collaboration between a public and a private cloud-based service of various types (IaaS, PaaS, SaaS).
Describe a multi-cloud infrastructure.
A multi-cloud infrastructure is when an individual of group makes use of multiple cloud providers, usually for specific purposes related to where certain service providers are stronger in a particular service or services that they provide.
Describe the Azure Arc service.
A service that allows for the management of Kubernetes clusters of machines, physical or virtual, for running applications within containers, which contain the dependencies and packages that they use.
Describe integration in terms of cloud computing.
Integration, in terms of cloud computing, is a measurement of how orderly various cloud-based systems and/or services collaborate with each other.
Describe scalability in terms of cloud computing.
Scalability, in terms of cloud computing, is a measurement of how well a cloud-based systems or services can adjust to changing levels of request and activity.
Describe agility in terms of cloud computing.
Agility, in terms of cloud computing, is a measurement of how quickly an individual or organization can adapt to a change or changes in environmental conditions that affect its necessities, using cloud-based computing
Describe elasticity in terms of cloud computing.
Elasticity, in terms of cloud computing, is a measurement of a cloud-based system to adapt automatically and appropriately, relative to changes in the amount of requests from users of that system.
Describe what vertical scaling is, in terms of cloud computing.
Vertical scaling is modifying a SINGLE virtual machine in order to increase scalability (the ability to adjust to higher or lower levels of activity).
