Azure Disk Storage: Azure Disk Storage provides high-performance, persistent storage disks for virtual machines (VMs). There are three main types of disks: Premium SSD, Standard SSD, and Standard HDD. Each tier offers different levels of performance and cost, ensuring flexibility to balance workload needs. Ideal for use cases such as:
- Database Workloads: Azure Disks provide SSD options for high-performance storage, ensuring low latency and reliability for transactional applications like databases (SQL Server, Oracle).
- Disaster Recovery and Backup: Azure Disk offers automated backup and point-in-time restore capabilities, making it easy to recover data after a disaster or failure.
Azure Archive Storage: Azure Archive Storage is a low-cost storage tier designed for data that is rarely accessed but must be retained for long periods, such as compliance data or records. Data stored in Archive Storage is optimised for long-term retention with lower access frequency. Key use cases include:
- Compliance and Retention: Many industries require organisations to retain data for extended periods to meet regulatory compliance. Archive Storage provides a cost-effective solution to store data for years, while still offering retrieval options when needed.
- Cold Data Storage: Ideal for backup storage and long-term data retention where access frequency is low but retention requirements are high.
Azure Queue Storage: Azure Queue Storage is a service that stores large numbers of messages that can be accessed from anywhere via authenticated HTTP or HTTPS. Each message can be up to 64 KB in size, and a queue can contain millions of messages. It is used primarily for decoupling components of cloud applications. Key use cases include:
- Message Queueing Between Microservices: For distributed systems, Queue Storage allows for asynchronous communication between services, helping balance workloads.
- Event-Driven Processing: Store and process messages from various parts of an application, like order processing systems or background tasks.
- Retry Logic and Fault Tolerance: Implement systems that ensure tasks are retried or fault-tolerant using message-based communication.
Azure Table Storage: Azure Table Storage is a NoSQL key-value store for storing large amounts of structured, non-relational data. It provides highly scalable storage for scenarios where data is indexed and accessed using partition and row keys. Key use cases include:
- IoT Data Storage: Store telemetry or log data generated by IoT devices for quick access and analysis.
- Web App Data Storage: Azure Table Storage is a fast and scalable solution for storing user data, preferences, and session information for large-scale applications.
- Metadata Storage: Store non-relational data such as logs, catalogues, or lightweight objects.
Azure NetApp Files: Azure NetApp Files is a high-performance, fully managed file storage service for enterprise applications, offering NFS and SMB protocols. It is designed for high-performance workloads like SAP, Oracle, and other heavy enterprise workloads.
