EXAMINING CLOUD CONCEPTS Flashcards
What is Software as a Service?
A cloud computing model that delivers applications over the Internet, allowing users to access software applications from any device with an Internet connection without the need for local installation.
Examples include applications like Google Workspace and Microsoft 365.
What is Platform as a Service?
An environment for developers to create, deploy, and manage application code, in the cloud. This eliminates the need for managing the runtime environment, operating systems, and hardware.
Examples include Google App Engine and Microsoft Azure.
What is Infrastructure as a Service?
Offers virtualized computing resources that can be accessed via the Internet, enabling users to scale and manage hardware, storage, and network capabilities online without physical hardware investment.
Examples include Amazon Web Services (AWS) EC2 and Microsoft Azure.
Why is the Shared Responsibility Model in the cloud important?
Understanding that the security and management tasks are divided between Cloud service providers (CSPs) and customers. Identifying these responsibilities vary by service model.
This model helps clarify security obligations for both parties.
What are the customer responsibilities in Infrastructure as a Service (IaaS)?
Operating systems, applications, data, and access management.
Customers must ensure their own security and compliance for these areas.
What are the CSP responsibilities in Infrastructure as a Service (IaaS)?
Physical servers, storage, and networking.
CSPs handle the underlying physical infrastructure.
What are the customer responsibilities in Platform as a Service (PaaS)?
Applications, data, and access to the environment.
Customers focus on developing and managing their applications.
What are the CSP responsibilities in Platform as a Service (PaaS)?
Physical servers, storage, networking, runtime environment, operating systems.
CSPs manage the platform infrastructure and environment.
What are the customer responsibilities in Software as a Service (SaaS)?
Managing user access and protecting user data.
Customers must ensure proper user management and data security.
What are the CSP responsibilities in Software as a Service (SaaS)?
Managing infrastructure (physical servers, storage, middleware, networking), applications, and security of the platform.
CSPs handle the entire application stack and its security.
What is elasticity in cloud computing?
The ability to dynamically scale computing resources up or down based on demand.
This feature allows for efficient resource utilization, ensuring that applications can handle varying workloads without manual intervention.
What is scalability in the cloud?
The capability to expand or reduce resources and services according to the changing demands of applications.
This enables systems to accommodate growth seamlessly, ensuring consistent performance and user experience as workload requirements evolve.
What is on-demand access in the cloud?
This allows users to automatically provision computing resources as needed without requiring human interaction with each service provider.
This characteristic enables immediate access and control over resources according to the users’ requirements.
What is broad network access in the cloud?
Ensures that services are available over the network and can be accessed through standard mechanisms by a wide range of devices, including: Mobile phones, Tablets, Laptops, Workstations.
This characteristic allows users to access applications and data from anywhere, providing mobility and convenience.
