Lesson 1Object storage internals: eventual consistency, REST APIs, buckets, metadata, scalability and use casesDis section look inside object storage systems, focusing on RESTful access, buckets, and metadata. Learners study eventual consistency, distribution and scaling mechanisms, and di workloads dat benefit most from object storage designs.
Buckets, objects, and key namingREST APIs and common operationsEventual consistency behavioursMetadata 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 storageDis section explore cloud storage options, including IaaS block, managed file, and object storage. Learners compare durability, performance, and cost, and see how cloud services differ from traditional on-premises storage designs and operations.

Learners analyse rebuild behaviour, write penalties, and practical guidance on selecting RAID for various workloads.

Learners compare access patterns, namespace organisation, and metadata handling to understand which model best suit different workload types.

Learners explore zoning, masking, and multipathing to design resilient, high-performance shared storage fabrics.

Learners review common architectures, performance behaviour, scalability limits, and when DAS is appropriate compared with NAS or SAN based solutions.

Learners examine deployment patterns, concurrency handling, and permission models dat protect data and control multiuser access.
NAS vs. file server: key differencesCore NAS components and data pathsSMB protocol basics and capabilitiesNFS protocol basics and versionsPermissions, ACLs, and identity mappingTypical NAS deployment patternsLesson 8Performance metrics and capacity metrics: IOPS, throughput, latency, capacity planning basics, utilisation and growth forecastingDis section explain key performance and capacity metrics, including IOPS, throughput, latency, and utilisation. Learners practice interpreting metrics, planning capacity, and forecasting growth to maintain reliable, efficient storage systems.
