Common Cloud Services
Compute services
- Virtual Machines: Windows/Linux VMs with configurable CPU/RAM/disk; shared physical hosts
- Container Instances: Run containers without managing servers; per-second billing
- Azure Kubernetes Service (AKS): Managed Kubernetes with integrated CI/CD and security
- Service Fabric: Distributed systems platform for reliable microservices
- Functions: Event-driven serverless compute; pay only for execution time
- Batch: Schedule and run large-scale parallel jobs; supports Spot VMs for cost savings
Storage services
- Blob Storage: Massively scalable object storage; multiple access tiers and lifecycle management
- Disk Storage: Durable block storage for VMs; SSD/HDD options; encryption at rest
- File Shares: SMB/NFS file shares; lift-and-shift file servers to Azure
- Queue Storage: Asynchronous messaging; up to millions of messages per queue
- Table Storage: NoSQL key-value store for semi-structured data
- Data Box: Rugged devices to move tens of TBsโPBs offline into/out of Azure
- Archive Storage: Lowest-cost tier for long-term, rarely accessed data
- Data Lake Storage: HDFS-compatible data lake for analytics workloads
Database services
- Cosmos DB: Globally distributed, multi-model NoSQL with 99.999% availability options
- Azure SQL Database: Managed relational database with autoscale and advanced security
Exam tips
- Know when to use VM vs. Containers vs. AKS vs. Functions
- Recognize the storage tiers and when to choose Blob vs. File vs. Disk
- Understand Cosmos DB (NoSQL) vs. Azure SQL (relational) scenarios
