Q3-5 What Are the Typical Cloud Options? Flashcards
What are the three main types of cloud service models?
The three main types of cloud service models are:
Software as a Service (SaaS): Provides applications over the internet.
Platform as a Service (PaaS): Provides platforms allowing customers to develop, run, and manage applications.
Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
What is Software as a Service (SaaS)?
SaaS provides software applications over the internet.
The service provider manages everything from the infrastructure to the application itself.
Examples include Salesforce.com and Microsoft Office Online.
What is Platform as a Service (PaaS)?
PaaS provides a platform allowing customers to develop, run, and manage their own applications without dealing with infrastructure management.
Examples include Microsoft Azure and Google App Engine (GAE).
What is Infrastructure as a Service (IaaS)?
IaaS provides virtualized computing resources, including servers, storage, and networking, over the internet.
The customer is responsible for managing the operating system and applications.
Examples include Amazon AWS and Google Compute Engine.
What are the key differences between SaaS, PaaS, and IaaS?
SaaS: Provides ready-to-use applications.
PaaS: Provides platforms for developers to build applications.
IaaS: Provides raw computing infrastructure.
How does cloud computing achieve economies of scale?
Cloud computing achieves economies of scale by allowing providers to offer services on a large scale, reducing the average cost per unit as the operation grows.
This is similar to how businesses can scale up production to reduce costs as the size of operations increases.
Can you provide an example of a SaaS cloud service?
Salesforce.com provides programs for customer relationship management (CRM) and sales tracking as a service.
Can you provide an example of a PaaS cloud service?
Microsoft Azure provides a platform with hosted Windows Servers for developers to build and manage applications.
Can you provide an example of an IaaS cloud service?
Amazon AWS provides virtual servers and storage services, allowing customers to manage their own operating systems and applications.
What are the benefits of using cloud computing?
Cloud computing provides benefits such as:
Cost savings due to economies of scale.
Flexibility and scalability.
Reduced need for physical infrastructure management.
Increased collaboration through web-based tools.
What makes it difficult to describe simple processes like making a sandwich?
Describing processes can be challenging because:
There are many assumptions made in daily tasks that are not always obvious.
People may skip steps or assume that certain actions are understood without explicitly stating them.
The granularity of detail needed can vary depending on the complexity and audience.
Why is it important for businesses to improve the process of listing activities?
Accurate activity lists help businesses clearly articulate their processes, improving efficiency, communication, and consistency.
It also reduces errors and allows for better analysis and optimization of tasks.
What is a private cloud?
A private cloud is a cloud infrastructure owned and operated by an organization for its own benefit.
It is elastic and internet-based, but not pooled with other organizations, keeping data and apps under the company’s physical control.
When might an organization choose to use a private cloud?
Organizations that are legally required to maintain physical control over their data, such as financial institutions or government agencies, may use a private cloud to maintain their own hosting infrastructure.
What is edge computing?
Edge computing refers to moving data storage and computation closer to where it is needed, rather than relying on a central location.
This can reduce delays and improve performance, particularly for technologies like driverless cars.
