S3 (Simple Storage Service)
AWS cloud object storage service offering near-unlimited scalability, 99.999999999% high availability, and storage classes tailored to different access patterns.
Bucket
Root container in object storage that groups similar objects, has a globally unique name, and configures permissions and policies at the group level.
Blob Storage
Microsoft Azure object storage service optimized for storing massive amounts of unstructured data such as text, images, or video files.
Immutable Storage
WORM (Write Once Read Many) storage mechanism that prevents data modification or deletion after writing, essential for regulatory compliance and ransomware protection.
Tiered Storage
Automatic data lifecycle management strategy that moves objects between different storage classes based on access frequency and storage costs.
CDN (Content Delivery Network)
Distributed network of edge servers that cache objects stored in the cloud to reduce latency and improve access performance for geographically distant users.
API RESTful
HTTP-based programming interface enabling CRUD (Create, Read, Update, Delete) operations on storage objects via standardized endpoints like PUT, GET, and DELETE.
Lifecycle Policies
Automated rules that transform or archive objects based on predefined criteria such as age, size, or access patterns to optimize storage costs.
Cross-Region Replication
Process of automatically synchronizing objects between buckets located in different geographical regions to ensure business continuity and data resilience.
Data Durability
Measure of the probability that an object remains intact and accessible over the long term, expressed in nines (e.g., 11 nines = 99.999999999% durability).
Versioning
Feature that preserves multiple variants of an object in the same bucket, allowing recovery of previous versions and protection against accidental or malicious deletions.
Access Control Lists (ACL)
Mechanism for defining granular permissions at the object and bucket level, specifying who can access, read, or write storage resources.
Cloud Storage Gateway
Appliance or virtual software that connects on-premise applications to cloud object storage by translating local storage protocols (NFS, SMB) into object APIs.
Serverless Storage
Storage model where the underlying infrastructure is completely managed by the cloud provider, allowing pay-per-use without managing physical servers.
Cold Storage
Economical storage class for rarely accessed data, offering reduced storage costs at the expense of longer retrieval times (hours).
Multi-Part Upload
Technique for transferring large objects that splits the file into smaller parts uploaded in parallel to improve transfer reliability and performance.
Object Lock
WORM functionality at the object level preventing deletion or modification during a defined retention period, used for regulatory compliance (SEC, FINRA).
Event Notification
Mechanism triggering automated actions (Lambda, SQS, SNS) during specific object events like creation, deletion, or modification.
Metadata
Set of descriptive data associated with each stored object including system headers and custom key-value pairs for indexing and search.
Encryption at Rest
Automatic encryption of objects on physical storage media using either provider-managed keys (SSE-S3) or custom keys (SSE-KMS).
Presigned URLs
Temporarily signed URLs granting time-limited access to private objects without requiring AWS credentials, used for secure downloads/uploads.
Storage Classes
Different cloud storage levels optimized according to access frequency (Standard, IA, Glacier) balancing costs, performance, and durability for different use cases.
