| Front | Back |
| Auto-scaling in Azure | Automatically adjust compute resources based on demand |
| Availability Sets | Enable redundancy for VMs by spreading them across multiple fault and update domains |
| Availability Zones | Physically separate datacenter locations within an Azure region for enhanced resiliency |
| Azure Application Gateway | Layer 7 load balancing service that provides TLS termination and web traffic distribution |
| Azure Backup | Integrated service for backing up and recovering data in Azure |
| Azure Cache for Redis | In-memory data store that improves application performance and scalability |
| Azure ExpressRoute | Private connection between on-premises infrastructure and Azure datacenters for greater reliability |
| Azure Front Door | Global service for web acceleration and application security with Dynamic Site Acceleration |
| Azure Resource Health | Reports on the health of individual Azure resources and recommends actions |
| Azure Service Health | Personalized alerting and guidance when Azure service issues affect you |
| Azure Traffic Manager | DNS-based load balancing across multiple service endpoints or regions |
| Content Delivery Network (CDN) | Distributed network that caches content closer to end users for better performance |
| Cosmos DB Multi-Region Writes | Global distribution feature allowing write operations in multiple regions |
| Fault Domains | Physical groupings of hardware to limit the impact of potential failures |
| Load Balancing | Distributes incoming network traffic across multiple healthy targets |
| Multi-region Deployment | Hosting services in more than one Azure region for high availability and low latency |
| Premium SSD v2 | High-performance storage option for Azure VMs with submillisecond latency |
| Read-Access Geo-Redundant Storage (RA-GRS) | Storage replication that provides read access to data in a secondary region |
| Recovery Point Objective (RPO) | Maximum acceptable data loss measured in time before a disaster |
| Recovery Time Objective (RTO) | Maximum acceptable time to restore a system after a disaster |
| Resiliency Design Patterns | Strategies like Circuit Breaker, Bulkhead, and Retry that improve application reliability |
| Scaling vertically vs horizontally | Vertical scaling adds power to existing servers while horizontal scaling adds more servers |
| Site Recovery | Orchestrates disaster recovery to secondary Azure regions or on-premises sites |
| SLA (Service Level Agreement) | Microsoft's commitment to uptime and connectivity for specific Azure services |
| Storage Redundancy Options | LRS/ZRS/GRS/RA-GRS options that protect data against failures |
| Transient Fault Handling | Techniques for managing temporary failures in cloud services including retry logic |
| Update Domains | Logical groupings that allow Azure to roll out updates with minimal downtime |
| Virtual Machine Scale Sets | Create and manage a group of identical VMs that can automatically increase or decrease |
| VM Proximity Placement Groups | Feature that minimizes the physical distance between VMs to reduce network latency |
| Zone-Redundant Storage (ZRS) | Replicates data synchronously across three storage clusters in different availability zones |
About the Flashcards
Flashcards for the Microsoft Azure Fundamentals exam help students review core Azure availability and scalability concepts with concise definitions and real-service examples. Cards cover auto-scaling, vertical vs horizontal scaling, VM Scale Sets, load balancing (Traffic Manager, Application Gateway, Azure Front Door), availability sets and zones, multi-region deployment, Azure Cache for Redis, and CDN.
Emphasis is on redundancy, recovery, and operational controls: fault and update domains, storage redundancy options (LRS, ZRS, GRS, RA-GRS), Azure Backup and Site Recovery, ExpressRoute, Premium SSD v2, VM proximity placement groups, plus resiliency design patterns (Circuit Breaker, Bulkhead, Retry), transient fault handling, SLAs, Azure Service Health, Resource Health, RTO and RPO.
Topics covered in this flashcard deck:
- Auto-scaling and scaling types
- Load balancing services
- Availability sets and zones
- Storage redundancy options
- Disaster recovery and backups
- Resiliency patterns and RTO/RPO
