Cloud Concepts - Cloud Service Models Flashcards
What are the most common cloud service models in the industry?
The most common cloud service models in the industry are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).
What is Software as a Service (SaaS)?
Software as a Service is a service model where applications are delivered over the internet and fully managed by the provider. Users can access the application without the need to install any software locally.
What is an example of Software as a Service (SaaS)?
An example of Software as a Service is Google’s email service, Gmail.
What level of customization does Software as a Service (SaaS) offer?
Software as a Service offers the least amount of customization to the application itself from the user’s perspective.
What is Platform as a Service (PaaS)?
Platform as a Service is a service model that provides users with an application framework on top of the operating system and infrastructure managed by the provider. It allows developers to focus on developing applications without managing the underlying infrastructure.
What level of management and control does Platform as a Service (PaaS) offer?
Platform as a Service offers a greater level of management and control compared to Software as a Service. It manages the underlying architecture, host hardware, network components, and operating system, while users focus on app development.
What is Infrastructure as a Service (IaaS)?
Infrastructure as a Service is a service model that allows users to customize and manage their own portion of the cloud. Users can configure a virtual network, deploy resources, and have control over the operating system and other layers of the infrastructure.
What level of customization does Infrastructure as a Service (IaaS) offer?
Infrastructure as a Service offers the highest level of customization as users can configure virtual networks, deploy various resources, and choose the operating system.
Are there other cloud service models besides SaaS, PaaS, and IaaS?
Yes, there are other service models such as Disaster Recovery as a Service (DRaaS), Communications as a Service (CaaS), and Monitoring as a Service (MaaS). However, these are not covered in this course.
