Flashcards do conjunto (20)
- 1What does IaaS stand for and what is its primary focus?Infrastructure as a Service; focuses on providing virtualized computing resources over the internet, including servers, storage, and networking.
- 2What are the cornerstones of IaaS offerings?Server virtualization, storage virtualization, and network virtualization.
- 3Who is responsible for managing the hypervisor and hardware in IaaS?The cloud provider manages the hypervisor and underlying hardware, while the consumer manages the VM configuration, OS, and patches.
- 4What does storage virtualization in IaaS allow?It allows cloud providers to offer storage solutions that can expand or change performance based on business needs.
- 5What is the purpose of network virtualization in IaaS?It enables the creation of isolated virtual private cloud networks for each customer, ensuring secure communication among VMs.
- 6Front: What does PaaS stand for and what does it provide?Platform as a Service; provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the infrastructure.
- 7How do PaaS solutions benefit application developers?They allow developers to deploy their code to a runtime environment that automatically scales based on application load, simplifying deployment and scalability.
- 8What is serverless computing, and how is it related to PaaS?A branch of PaaS designed to simplify app deployment by abstracting server management and scaling, allowing rapid deployment and scalability with minimal IT operations effort.
- 9What does SaaS stand for and what does it offer?Software as a Service; offers applications over the internet, allowing users to store and publish information without managing the underlying infrastructure or applications.
- 10Can you give examples of SaaS solutions?Social media (e.g., Facebook), word processing (e.g., Office 365), and business applications (e.g., Salesforce).
- 11What differentiates cloud deployment models from each other?The primary differentiator is responsibility for maintaining the infrastructure and facilities.
- 12What are the fundamental service models of cloud computing?Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
- 13What characterizes a private cloud?Hosted within a company's on-premises data center or co-located in a commercial data center, with the company maintaining complete control over the infrastructure.
- 14What is the primary advantage of a private cloud?Ownership and control over the equipment, often chosen for regulatory compliance or specific control needs.
- 15What is a public cloud?Cloud services provided by third parties like AWS, Microsoft Azure, or Google Cloud Platform, where the provider maintains the infrastructure.
- 16How do public clouds ensure security despite multi-tenancy?By isolating customer data, following strict data handling rules, and employing advanced security measures in physical data centers.
- 17What is a community cloud?A semi-private cloud jointly owned and operated by the tenants, often found in universities or government agencies for shared maintenance and management.
- 18What defines a hybrid cloud?A combination of private and public cloud environments, allowing for flexible resource use and adherence to regulatory controls for certain data or applications.
- 19How is connectivity achieved in a hybrid cloud model?Through a dedicated connection like a VPN over the internet or a WAN connection maintained by a telecommunications provider.
- 20What is a multi-cloud strategy?Utilizing services from multiple public cloud providers to leverage strengths of each and add redundancy and flexibility to cloud deployments.
