Virtual Machines and Networks in the Cloud Flashcards
(20 cards)
What is a Virtual Private Cloud (VPC)
A secure, individual, private cloud-computing model hosted within a public cloud, combining scalability and convenience with data isolation.
What is the scope of Google VPC networks
Google VPC networks are global.
What is the scope of subnets within Google VPC networks
Subnets can be in any Google Cloud region worldwide and can span the zones that make up a region.
What is Google Compute Engine
Google Cloud’s Infrastructure as a Service (IaaS) solution that lets users create and run virtual machines on Google infrastructure.
What does each virtual machine in Compute Engine contain
The power and functionality of a full-fledged operating system.
Name three ways to create a virtual machine instance in Google Compute Engine.,
Google Cloud console, Google Cloud CLI, or the Compute Engine API.
Which two server images are provided by Google for VMs
Linux Server images and Windows Server images.
What are “sustained-use discounts” in Compute Engine pricing
Automatic discounts applied to virtual machines the longer they run (e.g., more than 25% of a month).
What are “committed-use discounts” in Compute Engine pricing
Discounts (up to 57%) for committing to a usage term of one or three years for specific amounts of vCPUs and memory.
What is the main reason customers choose Preemptible or Spot VMs
To reduce cost (can save up to 90%).
What is the primary difference between a Preemptible/Spot VM and an ordinary Compute Engine VM regarding termination
Compute Engine has permission to terminate a Preemptible/Spot VM if its resources are needed elsewhere.
Name two types of Persistent Disks available for Compute Engine instances.
Zonal Persistent Disk and Regional Persistent Disk
What type of storage is Local SSD primarily used for
High performance, transient, local block storage.
What is the purpose of Autoscaling in Compute Engine
VMs can be added to or subtracted from an application based on load metrics to meet demand.
What is the main job of a Load Balancer
To distribute user traffic across multiple instances of an application.
What type of traffic do Application Load Balancers primarily handle
HTTP and HTTPS traffic (application layer / Layer 7).
What is the role of the Domain Name Service (DNS)
It translates Internet hostnames to addresses.
What is “edge caching” in the context of Cloud CDN
Storing content closer to end users using caching servers.
Which interconnect option uses a VPN “tunnel” connection over the Internet and Cloud Router to make it dynamic
Cloud VPN.
Which interconnect option allows for one or more direct, private connections to Google and can be covered by up to a 99.99% SLA
Dedicated Interconnect.
