Cloud Computing terminology Flashcards
What is Cloud?
In cloud computing, “cloud” is used as a metaphor for the Internet, so the phrase cloud computing means a type of Internet-based computing.
What are Cloud servivces?
Cloud services are applications, services, or resources made available to users on demand through the Internet such as:
Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software as a service (SaaS)
Data storage
What is a cluster in the cloud enviroment?
A computer cluster is a collection of interconnected stand-alone computers or servers that can work together as a single, integrated computing resource.
What are containers?
A container is a “wrapper” that allows software to travel between operating environments. Containers create a unique virtual instance of an operating system (OS) that separates an application from others in the same environment. Containers can run separate instances of an application within a single, shared OS.
what is Hybrid Cloud?
A hybrid cloud is a combination of traditional IT and public or private clouds (or both) that remain separate, but are bound together by technology that makes the data or application portable.
What is Infrastructure as service IaaS?
IaaS delivers computer infrastructure on an outsourced basis to support a company’s operations. It includes servers, network, operating systems, and storage, through virtualization technology which doesn’t require that the company physically maintain or manage it. Its cloud servers typically include a dashboard or an application programming interface (API) that gives the company control of the entire infrastructure.
Startups and small companies may prefer IaaS to avoid spending time and money buying and creating hardware and software such as servers, storage, or networking resources.
When you hear IaaS, think of computing, storage, and networking resources.
What is Kubernetes?
Kubernetes is an open-source platform for managing containerized workloads and services.
Explain Multicloud?
Multicloud is the use of more than one public cloud, a strategy that allows enterprises to choose specific services from a combination of public IaaS clouds such as IBM Cloud, Amazon Web Services, and Microsoft Azure. This enables companies to avoid locking in to any one cloud provider.
Difference of on premises and off premisses
On premises refers to a solution installed and hosted in-house. Private cloud is hosted in a company’s own data center.
A solution that is hosted on dedicated hardware that happens to be in a different physical location is referred to as off premises.
What is Platrform as a service (PaaS)?
PaaS provides cloud components for software programs. PaaS delivers a framework for developers that they can use to create customized applications. The platform typically includes an operating system, a programming language execution environment, a database, and a web server.
When you hear PaaS, think of development tools, database management, and business analytics.
What is Private Cloud?
A private cloud is an on-premises or off-premises cloud infrastructure operated solely for one organization. It may be managed by that organization or by a third party.
What is a public cloud?
A public cloud is available to the general public or a large industry group, owned and managed by an organization selling cloud services.
What is a Software as a Service?
SaaS refers to a model of software deployment where online software is provided as a service to customers.
When you hear SaaS, think of hosted subscription applications or web email, Google apps, or Dropbox.
Vitrualization
Virtualization is the creation of a virtual (rather than actual) version of something such as a server, a desktop, a storage device, an operating system, or network resources.
What is a virtual machine?
A virtual machine (VM) is a software program or operating system that behaves like a separate computer that can run applications and programs.
