It's distinct from object storage (S3-style), which serves whole files over HTTP. Why it matters: block storage is what you attach to a virtual machine to hold a database's data files, or anything needing low-latency random reads and writes and a real filesystem. It's fast and consistent, but tied to one instance at a time and to a single availability zone. Practical note: block volumes don't automatically survive the instance they're attached to — snapshot them regularly for backups, and remember that unused, unattached volumes keep billing quietly (a common FinOps cleanup target). Choose block storage for databases and stateful workloads; choose object storage for user uploads, backups, and static assets you serve to the world. Sizing and IOPS tiers directly affect both performance and cost.","Block storage hands a server raw volumes it formats and mounts like a physical disk — EBS, Persistent Disk — unlike object storage, which serves files over HTTP.",null,[11,14,17,20,23],{"slug":12,"name":13},"data-residency","Data Residency",{"slug":15,"name":16},"egress-fees","Egress Fees (Data Transfer Out)",{"slug":18,"name":19},"object-storage","Object Storage",{"slug":21,"name":22},"replication","Replication",{"slug":24,"name":25},"s3","S3",[27,31,34,38,41,42,45,48,51,54,57,60],{"slug":28,"category":5,"name":29,"updated_at":30},"autoscaling","Autoscaling","2026-08-24T02:46:37+00:00",{"slug":32,"category":5,"name":33,"updated_at":30},"availability-zone","Availability Zone (AZ)",{"slug":35,"category":5,"name":36,"updated_at":37},"disaster-recovery","Disaster Recovery","2026-08-24T02:46:38+00:00",{"slug":39,"category":5,"name":40,"updated_at":37},"edge-ai","Edge AI",{"slug":15,"category":5,"name":16,"updated_at":30},{"slug":43,"category":5,"name":44,"updated_at":30},"finops","FinOps (Cloud Financial Operations)",{"slug":46,"category":5,"name":47,"updated_at":37},"immutable-infrastructure","Immutable Infrastructure",{"slug":49,"category":5,"name":50,"updated_at":37},"infrastructure-drift","Infrastructure Drift",{"slug":52,"category":5,"name":53,"updated_at":30},"managed-kubernetes","Managed Kubernetes",{"slug":55,"category":5,"name":56,"updated_at":30},"multi-region","Multi-Region",{"slug":58,"category":5,"name":59,"updated_at":37},"noisy-neighbor","Noisy Neighbor",{"slug":61,"category":5,"name":62,"updated_at":30},"platform-as-a-service","Platform as a Service (PaaS)"]
