Q & A

What is the origin of the term 'cloud computing'?
-The term 'cloud computing' was created by the U.S National Institute of Standards and Technology.
What are the five key traits of cloud computing?
-The five key traits of cloud computing are on-demand self-service, broad network access, resource pooling, elasticity, and measured service.
How does on-demand self-service in cloud computing benefit users?
-On-demand self-service allows users to obtain processing power, storage, and network resources without human intervention through a web interface.
What does it mean for cloud computing resources to have 'broad network access'?
-Broad network access means that users can access computing resources over the internet from anywhere they have a connection.
How does resource pooling in cloud computing benefit the provider and the customers?
-Resource pooling allows the provider to have a large pool of resources, which they can allocate to users as needed. This enables the provider to buy in bulk and pass the savings onto the customers.
Why do customers not need to know the physical location of cloud computing resources?
-Customers don't need to know the exact physical location of resources because the cloud provider manages the infrastructure and ensures accessibility.
What is meant by the 'elasticity' of cloud computing resources?
-Elasticity refers to the ability of cloud computing resources to automatically increase or decrease as needed, allowing customers to scale up or down quickly.
How does the payment model in cloud computing differ from traditional IT services?
-In cloud computing, customers pay only for what they use or reserve as they go, unlike traditional IT services where they might pay for fixed resources regardless of usage.
What is the role of IT infrastructure in cloud computing?
-IT infrastructure in cloud computing is the underlying framework of facilities and systems that support the delivery of services, similar to how a city's infrastructure supports its functions.
How does the analogy of a city's infrastructure help in understanding IT infrastructure?
-In the analogy, people in the city represent users in IT, cars and bikes represent applications, and the services provided are like the applications running on the infrastructure.
What will be the focus of the course on IT infrastructure services provided by Google Cloud?
-The course will focus on exploring the IT infrastructure services offered by Google Cloud, helping participants understand what the services do and how to use them.

🌟 Introduction to Cloud Computing

The paragraph introduces cloud computing as a popular and versatile technology. It explains the term's origin from the U.S National Institute of Standards and Technology and outlines its five key characteristics: on-demand self-service, broad network access, resource pooling, elasticity, and pay-per-use. The analogy of IT infrastructure to a city's infrastructure is used to illustrate the concept, where IT infrastructure encompasses the foundational systems and services that support applications and users, similar to how a city's infrastructure supports its residents and services.

Keywords

💡Cloud Computing

Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, analytics, and intelligence, over the Internet (the cloud) to offer faster innovation, flexible resources, and economies of scale. In the video, it is described as a way of using IT resources that are on-demand, accessible over the internet, and provided from a large pool by a service provider, allowing for cost savings and flexibility.

💡On-Demand Self-Service

On-demand self-service is a characteristic of cloud computing where users can automatically provision computing resources without requiring human interaction with each service provider. The video script emphasizes that this allows users to get the processing power, storage, and network they need without any need for human intervention, showcasing the convenience and autonomy in accessing cloud services.

💡Internet Access

Internet access is the ability to connect to the internet and use its services. In the context of the video, it is highlighted as a core aspect of cloud computing, allowing customers to access computing resources from anywhere they have a connection, which underscores the mobility and global reach of cloud services.

💡Resource Pooling

Resource pooling in cloud computing involves the provider's ability to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. The video mentions that providers have a large pool of resources and allocate them to users from that pool, which enables economies of scale and cost efficiency.

💡Elasticity

Elasticity in cloud computing means the ability to scale resources up or down automatically according to the demand. The video script explains that resources are elastic, allowing customers to be flexible and adjust their resource usage as needed, which is crucial for managing costs and performance effectively.

💡Pay-as-you-go

Pay-as-you-go is a pricing model where users are charged for the services they use, rather than a fixed fee. The video script states that customers pay only for what they use or reserve as they go, which aligns with the utility-like billing of cloud services, allowing for cost control and avoiding over-provisioning.

💡Infrastructure

Infrastructure in IT refers to the fundamental physical and organizational structures needed for the operation of various systems and services. The video likens IT infrastructure to a city's infrastructure, including transportation, communications, and utilities, which are essential for the functioning of the city, just as IT infrastructure supports the operation of applications and services.

💡Google Cloud

Google Cloud is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products, such as Google Search, Gmail, and YouTube. The video script mentions that the course will explore the IT infrastructure services provided by Google Cloud, indicating that it will cover various services and how they can be utilized.

💡IT Infrastructure Services

IT infrastructure services are the foundational services that support the operations of an organization's IT environment. The video script suggests that the course will help learners become familiar with these services provided by Google Cloud, enabling them to understand their functionalities and how to use them effectively.

💡Processing Power

Processing power, or computational power, refers to the ability of a computer system to perform operations and process data. In the video, it is mentioned as one of the resources that customers can access on-demand, highlighting the flexibility of cloud computing in providing the necessary computational resources as needed.

💡Network

Network in cloud computing refers to the interconnected system of computers, servers, and other devices that communicate with each other. The video script includes network as one of the resources that can be accessed on-demand, emphasizing the importance of connectivity in cloud services and its role in enabling communication and data transfer.
