1.2 Fundamental Cloud Concepts Flashcards
(23 cards)
Define total cost of ownership (TCO).
A comprehensive assessment of all layers within the infrastructure and other associated costs across the business over time. Includes acquiring hardware and software, management and support, communications, and user expenses, and the cost of service downtime, training, and other productivity losses.
Define capital expenditures (CapEx).
Upfront business expenses put toward fixed assets. Organizations buy these items once, and they benefit their business for years.
Define operating expenses (OpEx).
Recurring costs for a more immediate benefit. This represents the day-to-day expenses to run a business
Define IP address.
The IP stands for Internet Protocol, and this address is a series of numbers that can identify a network or the location of a particular device on a network.
Define internet service provider (ISP).
A rich ecosystem of companies and local providers build a global infrastructure that provides businesses and people around the world with the best possible internet experience. ISPs provide access to the internet to both personal and business customers, handling the traffic between the customer and the internet as a whole.
Define domain name.
An easy-to-remember name that maps directly to an IP address or set of IP addresses on the internet. It’s the unique name that appears after the @ sign in email addresses and after www. in web addresses.
Define domain name server (DNS).
A DNS server stores a database of domain names mapped to IP addresses that can be queried and used by computers to communicate with each other. This system is like the phone book of the web.
Define regions.
Independent geographic areas where Google Cloud resources are deployed, composed of zones.
Define zones.
A geographic area where Google Cloud resources are deployed.
Define fiber optic.
Contain one or more optical fibers, which are thin strands made of glass or plastic. These fibers are used to transmit data as pulses of light over long distances.
Define subsea cables.
Subsea fiber-optic cables carry 99% of international network traffic.
Define edge.
The place where a device, or an organization’s network, connects to the internet. It’s called the “edge” because this is the entry point to the network.
Define edge network.
How we connect with ISPs to get traffic to and from users. It’s made up of network infrastructure that organizations can hand off traffic to based on user needs, performance, and cost.
Define data centers.
Google owns and operates data centers all over the world. In these Google data centers, products like Search, Gmail, YouTube, and Google Cloud are run for people and organizations around the world, 24 hours a day, seven days a week.
Define latency.
he time it takes for data to travel from one point to another. Often measured in milliseconds, latency, sometimes called lag, describes delays in communication over a network.
The amount of time it takes for data to travel from one point to another
Measured in milliseconds
Describes delays in communication over a network
Define bandwidth.
A measure of how much data a network can transfer in a given time.
A measure of how much data a network can transfer in a given amount of time
Measured in megabits per second (Mbps) or gigabits per second (Gbps)
Higher bandwidth allows a computer to download information more quickly
Explain how an organization’s transition from an on-premises environment to the cloud shifts its capital expenditures (CapEx) to operational expenditures (OpEx) and how that affects its total cost of ownership (TCO).
Data centers require a huge CapEx investment up front as organizations purchase space, equipment, and software and hire a workforce to run and maintain everything. Forecasting is based on a metric such as historic growth to determine the needs for the next month, quarter, year, or even multiple years.
Moving to cloud’s on-demand OpEx model enables organizations to pay only for what they use and only when they use it. Budgeting is no longer a one-time operational process completed annually. Instead, spending must be monitored and controlled on an ongoing basis due to the dynamic nature of cloud use within organizations.

Discuss how Google Cloud supports data centers connected by a fast, reliable network.
Provides exceptional user experience and high performance
Makes it easy to communicate and manage data globally
Can scale without needing to add hardware
Google responds to that request from an edge network location that will provide the lowest latency.
Discuss how Google Cloud supports digital transformation with global infrastructure.
Network of fiber-optic cables that run on both land and sea.
Connects our data centers and points of presence
Owns and operates data centers all over the world
Based in five major geographic locations: North America, South America, Europe, Asia, and Australia.
Each of these locations is divided into several different regions and zones.
Some services support placing resources in a multi-region.
