A

Virtual machines
Containers
Azure App Service
Serverless computing

68
Q

This is an on-demand computing service for running cloud-based applications. This provides computing resources like multi-core processors and supercomputers via virtual machines and containers. This also provides serverless computing to run apps without requiring infrastructure setup or configuration. The resources are available on-demand and can typically be created in minutes or even seconds.

A

Azure compute

69
Q

Unlike VMs, these don’t include an operating system for the apps running inside the container. Instead, these bundle the libraries and components needed to run the application and use the existing host OS running underneath.

A

Containers

70
Q

Azure App Service falls into this cloud category of computing.

A

Platform-as-a-service (PaaS)

71
Q

This is a cloud-hosted execution environment that runs your code but completely abstracts the underlying hosting environment. You create an instance of this, and you add your code; no infrastructure configuration or maintenance is required, or even allowed.

A

Serverless computing

72
Q

Azure Virtual Machines (VMs) falls into this category of cloud computing.

A

Infrastructure as a service (IaaS)

73
Q

A

Update domains

75
Q

A group of virtual machines that share common hardware are in the same this.

A

Azure Virtual Machine Scale Set

77
Q

The task of automating, managing, and interacting with a large number of containers is known as this.

This is a collection of functions or steps, that are executed to accomplish a complex task.

A

Orchestration

78
Q

This architecture is where you break solutions into smaller, independent pieces. For example, you may split a website into a container hosting your front end, another hosting your back end, and a third for storage.

A

microservice architecture

79
Q

This lets you provision Azure Cloud Services directly from Kubernetes or Cloud Foundry

A

Open Service Broker for Azure (OSBA)

80
Q

This allows you to run a program (.exe, Java, PHP, Python, or Node.js) or script (.cmd, .bat, PowerShell, or Bash) in the same context as a web app, API app, or mobile app. They can be scheduled, or run by a trigger. These are often used to run background tasks as part of your application logic.

A

Web jobs

81
Q

This encompasses three ideas: the abstraction of servers, an event-driven scale, and micro-billing.

A

Serverless computing

82
Q

The two implementations of serverless compute/computing are:

A
