Cloud Basics
a metaphor for the network of data centers which store and compute information that’s available through the internet describing a complex web of software, servers, computers, networks, and security systems.
Cloud
when an organization uses new digital technologies, such as public, private, and hybrid cloud platforms to create or modify business processes, culture, and customer experiences to meet the needs of changing business and market dynamics.
digital transformation
hardware and software applications that are hosted on-site, located and operated within an organization's data center to serve their unique needs.
On-premises IT infrastructure (on-prem)
on-demand computing services and infrastructure are managed by a third-party provider, such as AWS or Google Cloud, and shared with multiple organizations or “tenants” through the public internet.
public cloud
offers compute and storage services.
infrastructure as a service (IaaS)
offers a develop-and-deploy environment to build cloud apps.
platform as a service (PaaS)
delivers apps as services, where users get access to software on a subscription basis.
software as a service (SaaS)
applications run in a combination of different environments: example is combining a public and private cloud environment, like an on-premises data center and a public cloud computing environment, like Google Cloud.
hybrid cloud
architectures that combine at least two public cloud providers.
multicloud
an environment for app and infrastructure modernization, data democratization, people connections, and trusted transactions.
transformation cloud
software that follows particular specifications that are openly accessible and usable by anyone.
open standard
software whose source code is publicly accessible and free for anyone to use, modify, and share.
open source
work environment that supports a mix of in-person and remote interactions, including immersive digital and mobile experiences
collaboration
helps organizations protect what's important with advanced security tools by finding ways to identify and protect everything from people and customers to data and transactions in a fast-changing environment
Trust (one of the capabilities that forms the basis of the transformation cloud.)
where an organization is in its cloud journey and actionable programs that get it to where it wants to be. It can quickly reveal any areas where an organization might be weaker or underinvested.
cloud maturity assessment
weighs the cost of cloud adoption against the cost of running their current on-premises systems
cloud total cost of ownership (or TCO) analysis
are upfront business expenses put toward fixed assets
Capital expenditures (CapEx)
Recurring costs that represent the day-to-day expenses to run a business.
Operating expenses (OpEx)
provide access to the internet to both personal and business customers, handling the traffic between the customer and the internet as a whole.
internet service providers (or ISPs)
a series of numbers that can identify a network or the location of a particular device on a network
IP address (Internet Protocol address)
an easy-to-remember name that maps directly to an IP address or set of IP addresses on the internet
domain name
is like the phone book of the web that translates a web address like "www.google.com" into the IP address of the computer hosting that site
Domain Name System, or a DNS
a measure of how much data a network can transfer in a given amount of time
bandwidth
is the amount of time it takes for data to travel from one point to another
latency
is a security model commonly used in cloud computing, which outlines the respective security responsibilities of the cloud service provider and the user.
Shared responsibility model
