Knowledge of storage architectures and types

Storage Architectures and Types

File Storage:

Data is stored in a hierarchical structure with directories and files. Examples: Network Attached Storage (NAS), local hard drives. Use Cases: File sharing, document storage.

Block Storage:

Data is stored in fixed-sized blocks and managed by an operating system. Examples: Storage Area Networks (SAN), cloud block storage (e.g., AWS EBS). Use Cases: Databases, virtual machine disk storage.

Object Storage:

Data is stored as objects with metadata and unique identifiers. Examples: Amazon S3, Google Cloud Storage. Use Cases: Media storage, backups, and large datasets.

Backup and Disaster Recovery (DR) Strategies:

Backups: Periodic copies of data for restoration. Types: Full, Incremental, Differential. Disaster Recovery: Strategies to resume operations after a catastrophic event. Methods: Data replication, cloud-based DR, DR-as-a-Service (DRaaS).

Content Delivery Networks (CDNs) Distributes content across multiple servers worldwide to ensure faster delivery to end-users. Key Benefits: Reduced latency, improved load times, scalability. Examples: Cloudflare, Akamai, AWS CloudFront.

Email/Messaging Services Email Services:

Facilitate the sending, receiving, and managing of emails. Examples: Microsoft Exchange, Gmail, SendGrid. Messaging Services:

Enable real-time or asynchronous text communication. Examples: Twilio, WhatsApp Business API, Slack.
