Cloud Computing Concepts (CloudNetX CNX-001) Flashcards
CompTIA CloudNetX CNX-001 Flashcards
| Front | Back |
| Advantages of cloud computing | Scalability, cost-efficiency, flexibility, reliability, and easy access to resources. |
| Difference between capital and operational expenses in cloud computing | Capital expenses involve upfront costs for physical hardware, while operational expenses are ongoing costs like cloud services. |
| Difference between containers and virtual machines | Containers share the host OS kernel, while virtual machines include a full OS and are more resource-intensive. |
| Difference between elasticity and scalability | Elasticity refers to automatic resource adjustments, while scalability refers to adding resources as needed. |
| Examples of IaaS providers | AWS EC2, Microsoft Azure, Google Compute Engine. |
| Examples of PaaS providers | Heroku, AWS Elastic Beanstalk, Google App Engine. |
| Examples of SaaS providers | Google Workspace, Salesforce, Dropbox. |
| Key benefit of IaaS | Scalability and control over computing resources without owning physical hardware. |
| Key benefit of PaaS | Simplifies the application development process by abstracting infrastructure management. |
| Key benefit of SaaS | Offers ready-to-use applications accessible from anywhere with an internet connection. |
| Key difference between public and private clouds | Public clouds are shared among multiple users, while private clouds are dedicated to a single organization. |
| Key factor for hybrid cloud adoption | Flexibility to maintain sensitive data on-premises while leveraging the scalability of public clouds. |
| Primary goal of cloud deployment models | To determine who has access to cloud resources and how they are managed. |
| Security benefit of private cloud | Enhanced control, compliance, and data protection tailored to organizational needs. |
| What is a cloud access management system | A system for defining and enforcing policies to control user access to cloud resources. |
| What is a cloud availability zone | A distinct location within a cloud region that operates independently to ensure fault tolerance. |
| What is a cloud computing service model | The framework for categorizing cloud offerings based on the level of control and abstraction provided to users (e.g., IaaS, PaaS, SaaS). |
| What is a cloud region | A specific geographic location where a cloud provider's data center or group of data centers is located. |
| What is a cloud service provider | A company that offers cloud computing services such as storage, computing power, and network solutions. |
| What is a cloud-native application | An application designed to fully exploit the scalability, flexibility, and resilience of cloud computing platforms. |
| What is a community cloud | A community cloud is shared infrastructure between organizations with common operational goals or compliance needs. |
| What is a container in cloud computing | A lightweight software environment that packages applications and their dependencies to run consistently across environments. |
| What is a hybrid cloud | A hybrid cloud combines public and private clouds, allowing data and applications to be shared between them. |
| What is a hypervisor | A hypervisor is software that enables the virtualization of physical hardware by creating and managing virtual machines. |
| What is a private cloud | A private cloud is a dedicated cloud environment accessible only by a single organization for greater control and security. |
| What is a public cloud | A public cloud is a cloud environment that is open for use by multiple organizations and provided by third-party providers. |
| What is API management in cloud services | Tools and systems that enable organizations to create, deploy, secure, and monitor APIs used in cloud computing. |
| What is cloud computing | The delivery of computing services like servers, storage, databases, networking, software, and analytics over the internet. |
| What is cloud migration | The process of moving data, applications, or workloads from on-premises infrastructure or another cloud provider to a cloud environment. |
| What is data redundancy in the cloud | Storing copies of data across multiple locations or systems to enhance reliability and prevent data loss. |
| What is disaster recovery in cloud computing | A set of strategies and processes to restore cloud services and data in case of system failure or interruption. |
| What is edge computing | The practice of processing data closer to its source, reducing latency and improving performance in IoT and real-time applications. |
| What is elasticity in cloud computing | The ability to automatically adjust resources to meet fluctuating demand. |
| What is horizontal scaling in cloud computing | Adding more instances or machines to handle increased workload. |
| What is IaaS | Infrastructure as a Service provides virtualized computing resources like servers, storage, and networking over the internet. |
| What is infrastructure redundancy | Infrastructure redundancy involves deploying backup systems to ensure high availability and reliability. |
| What is multitenancy | Multitenancy is a cloud architecture where multiple users share the same computing resources securely. |
| What is PaaS | Platform as a Service provides a platform to build, test, and deploy applications without managing the underlying infrastructure. |
| What is SaaS | Software as a Service provides software applications over the internet without requiring installation or maintenance. |
| What is scalability in cloud computing | The ability to increase resources to handle growing workloads. |
| What is serverless computing | A cloud model where the cloud provider dynamically manages the server infrastructure, allowing developers to focus solely on code. |
| What is the difference between public IP and private IP in the cloud | Public IPs are accessible over the internet, while private IPs are used within a private network and inaccessible from outside. |
| What is the pay-as-you-go pricing model | Paying only for the cloud resources you use without needing to invest in upfront hardware costs. |
| What is the shared responsibility model in cloud security | A framework that outlines the security responsibilities of both cloud providers and customers. |
| What is vertical scaling in cloud computing | Enhancing the capacity of an existing server by adding more CPU, RAM, or storage. |
| What is virtualization | Virtualization is the creation of virtual versions of physical hardware, enabling multiple systems to run on one physical machine. |
This deck covers fundamental cloud computing concepts, including service models (IaaS, PaaS, SaaS) and deployment models (public, private, hybrid, community).
