Match data to object, block, or file storage tiers by access pattern, consistency, and cost per operation. Use when choosing cloud storage for a workload or auditing storage spend and latency.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cloud storage selection Storage classes differ by orders of magnitude in latency, throughput, and cost per GB versus per operation. Pick by access pattern first, durability/consistency second, unit cost third; the wrong axis order produces expensive surprises. ## Method 1. **Start from the access pattern.** Write-once-read-many blobs (assets, backups, data lake): object storage. Random-access block I/O for one instance (databases, filesystems): block volumes. Shared POSIX semantics across many instances (legacy apps, some ML training): file storage, the most expensive convenience. Streaming append + replay: a log system, not storage at all (see message-queues). 2. **Object storage is the default; learn its physics.** Effectively infinite scale, 11-nines durability, strong read-after-write consistency on the majors now, but: latency per request is tens of ms (batch small objects; millions of 4KB files is an anti-pattern), listing is expensive, renames are copies, and per-request pricing punishes chatty access. Design keys for your read patterns (prefix = partition; see data-partitioning) and serve users through …

How to install
mdr add amey-thakur/ai-skills/cloud-storage-selection@sha256:f136990d200646d8The line at the top of this page pins the label git:20260720.3c9eba4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
