Lesson 1Object storage internals: eventual consistency, REST APIs, buckets, metadata, scalability and use casesWe dive into how object storage works, looking at REST access, buckets, and metadata. You'll learn about eventual consistency, how data spreads out, scaling tricks, and workloads that suit object storage best.
Buckets, objects, and key namingREST APIs and common operationsEventual consistency behaviorsMetadata indexing and searchScaling out capacity and throughputObject storage use cases and limitsLesson 2Cloud storage models: IaaS block storage, managed file storage, object storage, and differences from on-premises storageHere we check out cloud storage choices like IaaS block, managed files, and object storage. You'll see how they stack up on durability, speed, and cost, plus how they differ from traditional local server storage.

You'll look at rebuild processes, write costs, and tips on picking RAID for different jobs.

You'll compare access ways, folder setups, and metadata handling to see which fits various workload types.

You'll explore zoning, masking, and multipathing to build tough, fast shared storage networks.

You'll review common setups, speed traits, scaling limits, and when DAS works better than NAS or SAN options.

You'll check deployment styles, handling multiple users, and permission setups to safeguard data and manage access.

You'll practice reading metrics, planning space, and predicting growth for steady, efficient storage.

You'll study keep periods, RPO/RTO aims, and mixing tech and schedules to hit compliance, recovery, and business needs.
