What is cloud computing?
✔✔ Cloud computing is the delivery of computing services, including storage, processing, and
software, over the internet, allowing for on-demand access to resources.
What are the key characteristics of cloud computing?
✔✔ The key characteristics include on-demand self-service, broad network access, resource
pooling, rapid elasticity, and measured service.
What is the difference between IaaS, PaaS, and SaaS?
✔✔ IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet,
PaaS (Platform as a Service) offers a platform for developing, testing, and deploying
applications, and SaaS (Software as a Service) delivers software applications via the internet.
What is a public cloud?
✔✔ A public cloud is a cloud computing model where services are delivered over the internet
and shared among multiple organizations, typically hosted by a third-party provider.
1
,What is a private cloud?
✔✔ A private cloud is a cloud environment dedicated to a single organization, providing greater
control and security over data and resources.
What is a hybrid cloud?
✔✔ A hybrid cloud combines public and private cloud elements, allowing for data and
applications to be shared between them for greater flexibility and optimization.
What are the benefits of using cloud services?
✔✔ Benefits include cost efficiency, scalability, improved collaboration, enhanced security, and
automatic updates.
What is cloud elasticity?
✔✔ Cloud elasticity refers to the ability to automatically scale resources up or down based on
demand, ensuring optimal performance without over-provisioning.
What is the role of virtualization in cloud computing?
2
, ✔✔ Virtualization allows multiple virtual instances of computing resources to run on a single
physical machine, improving resource utilization and flexibility.
What are cloud service models?
✔✔ Cloud service models are frameworks that define how cloud services are delivered and
consumed, including IaaS, PaaS, and SaaS.
What is multi-tenancy in cloud computing?
✔✔ Multi-tenancy is a principle in cloud computing where multiple customers share the same
infrastructure and application while keeping their data isolated.
What is the importance of cloud security?
✔✔ Cloud security is critical to protect sensitive data and applications from unauthorized access,
breaches, and other vulnerabilities in a shared environment.
What is a service-level agreement (SLA)?
✔✔ A service-level agreement (SLA) is a contract between a service provider and a customer
that outlines the expected level of service, including performance metrics and responsibilities.
