Understanding Cloud Models Flashcards
What defines a Private Cloud?
A Private Cloud is dedicated to a single customer and is privately hosted, offering a self-service model with no outside access. It provides better security and privacy but involves high upfront costs and more responsibility for managing hardware.
What are the responsibilities of the customer in a Private Cloud environment according to the shared responsibility model?
The customer is responsible for managing information and data, devices (mobile & PCs), and accounts and identities across all Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and On-premises environments.
How does responsibility vary across different cloud service types within a Private Cloud?
Responsibility for identity and directory infrastructure, applications, network controls, and operating systems varies between being solely managed by the cloud provider or shared with the customer, depending on the cloud service model.
What are the primary deployment types of cloud models?
The primary deployment types of cloud models are Private Cloud, Public Cloud, and Hybrid Cloud, each offering different trade-offs in terms of privacy, control, flexibility, and costs.
What characterizes a Public Cloud?
A Public Cloud is hosted by a third-party provider, requires no upfront investment, offers more flexibility, and the vendor is responsible for managing the hardware. However, it involves shared tenancy with other users.
What is the Hybrid Cloud model?
The Hybrid Cloud model combines elements of both private and public clouds, allowing organizations to maintain control over certain workloads while leveraging the scalability and flexibility of public cloud resources.
What are some variations of the Hybrid Cloud model?
Variations include Multi-cloud Hybrid model, which connects multiple public clouds like AWS, Azure, and Google Cloud, and Azure Arc, which extends Azure management to non-Azure resources.
What are the key characteristics and trade-offs of each cloud model?
Private Cloud offers full control and privacy but requires a lot of maintenance and upfront costs. Public Cloud is available to anyone with no upfront costs but provides less control. Hybrid Cloud offers the most flexibility but entails more complexity, allowing organizations to connect public cloud with private workloads.
