01 Digital Transformation with Google Cloud Flashcards
What is the cloud?
The cloud is the network which describes the software, hardware
What is digital transformation?
When an organization uses new digital technologies (cloud models) to create or modify businesses processes, culture and customer experiences to meet the needs of changing business and market dynamics.
Digital transformation is an ongoing process, not a one time thing.
What is a paradigm shift?
A paradigm shift is a fundamental and irreversible change in the way that humans work and engage with the world.
What is an on-premises infrastructure?
Hardware on-site, the traditional way that doesn’t need third party access.
Organizations must have enough servers, space, and cooling; expert personel. It’s difficult to expand and needs a budget.
What is a private cloud infrastructure?
Also named single tenant or corporate cloud.
Hosted within an organizations private servers, third party or a private cloud provider. Self-service, scalable and elastic model. Businesses are more inclined to use this model if they’ve already invested on their data structure or if for regulatory reasons they need to keep their info on a certain way.
Its accessed through the internet and provides more customization.
What is a public cloud infrastructure?
A multi-tenant cloud infrastructure. The info is on one cloud, hidden from the other tenants. On-demand availability of resources, no need to configure, manage or acquire resources and pay for what they use.
- IaaS
- PaaS
- SaaS
What is a hybrid cloud infrastructure?
The use of an on-premises infrastructure along with the public cloud.
About 80% of responders use this model.
Used when an organization has made a significant infrastructure investment and for regulatory reasons data must be kept on premises. It offers self-service, scalability and elasticity.
What is a multicloud infrastructure?
The use of at least two cloud providers.
ie. multiple public clouds and hybrid cloud. 89%
Used when an organization wants to take advantage of the key strenghts in each provider.
What are the benefits of cloud computing?
- scalability: latest technology on-demand, budget is not a problem
- flexible: scales up and down with access anywhere with internet
- agile: quick development apps without having to worry about infrastructure
- strategic value: competitive advantages because of the continuous development, higher return on investment. Helps innovate and create new ideas.
- secure: stronger than data centers, dedicated teams
- cost-effective: pay for what you use, no need to overbuild data centers, IT staff to work on inniciatives
What is the VM Cloud Era?
The era where virtual machines removed the need to buy hardware, allowing companies like Spotify to operate more efficiently.
What characterizes the Infrastructure Cloud Era?
Migration to cloud for cost savings, faster development, better security, and reduced management load, enabling new capabilities.
How is Digital Transformation (DT) defined beyond cost savings and migration?
DT aims to optimize every environment to drive the highest levels of innovation within a company.
What is the focus of the Transformation Cloud Era?
- Spreading transformation across all teams
- Modernizing apps and infrastructure
- Enabling data democratization, connections, and trusted transactions
- Built on user-friendly platforms for sustainable growth
What are some challenges and needs of the Transformation Cloud Era?
- Best understanding and using data: to get better insights and reduce costs.
- Best technology infrastructure: foundation for growth an d market needs.
- Hybrid Workspace: intentional connections and collab.
- Secure: protect the company and its customers.
- Prioritize Sustainability: minimize environmental impact.
What are the bases of Transformation Cloud?
- data: make organizations data based at great scale, speed, security and reliability
- open infrastructure: use of hybrid approaches and open source software. Open standard (software that follows specifications and guidelines) and open source (software with public source code, free for anyone to use and modify)
- collaboration: increased flexibility secure collaboration both in-person and remote
- trust: better visibility to remediate threats and maintain control
- sustainable technology: by 2024 save 1 billion CO2 emissions
What are two capabilities that form the basis of a transformation cloud?
Data cloud provides a unified solution to manage data across the entire data lifecycle.
Open infrastructure gives the freedom to innovate by running applications in the place that makes the most sense.
Which item describes a goal of an organization seeking digital transformation?
Break down data silos and generate real time insights.
An organization has made significant investments in their own infrastructure and has regulatory requirements for their data to be hosted on-premises. Which cloud implementation would best suit their needs?
Private Cloud
An organization has a new application, and user subscriptions are growing faster than on-premises infrastructure can handle. What benefit of the cloud might help them in this situation?
It’s scalable, so the organization could shorten their infrastructure deployment time.
What is the cloud?
A metaphor for a network of data centers.
As the world and business changes, organizations have to decide between embracing new technology and transforming, or keeping their technology and approaches the same. What risks might an organization face by not transforming as their market evolves?
Focusing on ‘how’ they operate can prevent organizations from seeing transformation opportunities.
What does Total Cost of Ownership measure?
TCO evaluates the cost of cloud adoption compared to current on-premise systems.
Why is it challenging to predict TCO for cloud adoption?
Because of the dynamic nature of the cloud. Companies should also avoid directly comparing TCO with current on-prem running costs.
How do on-prem and cloud costs differ?
On-prem: depends on hardware, cooling, power, maintenance and support services.
Cloud: depends on monthly subscriptions or pay-per-use models
What is CapEx?
Capital Expenditure is the upfront expenses put toward fixed assets. Companies buy them once.
It can be challenging for small businesses.
What is OpEx?
Operating Expenses are the day to day expenses to run a business. Not considered long term.
What are the benefits of using the multicloud?
- access to the latest innovations from each provider.
- modernize at the right pace
- improved return on investment, expanding without increasing data center expenses
- flexiblity through choice of tools
- improved reliability and resiliency
- maintaining regulatory compliance
- running apps on-premises
- running apps on remote locations
How does a Network Operate?
Through fiber-optic networks made out of plastic or glass, or internet service providers (ISPs).
Google’s network runs on land an sea by optic cables.
What is an IP address?
A series of numbers that identify a network or location on a device.
What is a domain name?
An easy to remember name that matches or translates to an IP address or addresses on the internet.
What is the Domain Name System or DNS?
It works like a phonebook for the internet which connects the domain name with the IP address. A DNS server stores the domain names mapped to IP addresses that can be queried and used by computers to communicate with each other.
What is bandwidth?
How much data a network can transmit in a given amount of time. Measured in megabits per second (Mbps) or (Gbps).
Home internet has 100 Mbps to 1+ Gbps
Data center, 10 to 100 Gbps
What is latency?
The amount of time it takes for data to travel from one point to another. Measured in miliseconds. The closer to zero, the better.
