AZ-900 Cloud Concepts & Core Principles Flashcards
Microsoft Azure Fundamentals AZ-900 Flashcards
| Front | Back |
| Agility in cloud computing | Enables rapid provisioning and adjustment of resources for faster innovation |
| Azure Advisor | Free Azure service providing best practice recommendations on performance security and cost |
| Azure availability zones | Physically separate datacenters within a region for enhanced resiliency and fault tolerance |
| Azure Cost Management | Helps monitor and optimize financial spending on Azure resources |
| Azure global infrastructure | Microsoft’s worldwide network of data centers hosting Azure services |
| Azure Marketplace | Online catalog offering certified open-source and enterprise applications for Azure |
| Azure region pairs | Two linked regions in the same geographic area for disaster recovery and high availability |
| Azure Regions | Geographical areas containing at least one datacenter linked by low-latency networks |
| Azure Resource Groups | Logical containers used to manage and organize Azure resources as a single unit |
| Azure Role-Based Access Control (RBAC) | Granular permission system assigning roles to users groups or services for resource access |
| Azure Service Level Agreement (SLA) | Specifies Microsoft’s commitments for uptime and performance of Azure services |
| Azure Subscription | An agreement that grants access to Azure services with resources billed to an account |
| Azure Virtual Network (VNet) | Fundamental building block in Azure for securely communicating between resources |
| Cloud disaster recovery | Utilizes offsite data replication and failover to ensure business continuity |
| Cloud Migration to Azure | Process of moving applications and data from on-premises or other clouds to Azure |
| Consumption-based pricing model | Pay for only the specific resources and services used |
| Definition of IaaS (Infrastructure as a Service) | Provides virtualized computing resources like servers networking and storage |
| Definition of PaaS (Platform as a Service) | Offers a development environment for building and deploying applications |
| Definition of SaaS (Software as a Service) | Delivers software applications over the internet on a subscription basis |
| Economies of scale in cloud computing | Cloud providers use large-scale operations to lower costs passed on to customers |
| Elasticity in cloud computing | Automatically scaling resources up or down based on demand |
| Fault tolerance in cloud environments | Building systems design to continue operating despite failures |
| High availability in cloud computing | Ensuring systems are continuously operational with minimal downtime |
| Hybrid cloud model | Combines public and private clouds allowing data and apps to move between them |
| Key benefit of cloud computing | Scalability to quickly meet changing demands |
| Multi-Factor Authentication (MFA) in Azure | Security method requiring two or more credentials to verify user identity |
| OpEx vs CapEx in cloud context | OpEx is pay-as-you-go operational expense while CapEx is upfront capital expense |
| Private cloud model | Cloud environment dedicated to a single organization for greater control |
| Public cloud model | Services offered over the public internet available to anyone |
| Regulatory compliance in Azure | Adheres to frameworks like GDPR ISO PCI and HIPAA for data protection |
| Serverless computing | Focuses on running code without managing underlying servers and scales automatically |
| Shared responsibility model in Azure | Azure secures the infrastructure while customers manage data identities and endpoints |
| What is cloud computing | The on-demand delivery of computing services over the internet with pay-as-you-go pricing |
This deck covers the fundamentals of cloud computing as they apply to Azure. It includes definitions, benefits, and service models like IaaS, PaaS, and SaaS, helping you understand the basics before diving into more complex Azure services.
