Cloud Whatis

Dictionary of cloud stuff. (Work in progress… Last updated: 2021-04-28.)

See also: Cloud Native (Bookmarks).

(Skip preliminaries — to dictionary.)

Format

  1. I am considering converting this into an app, adding features. Blog post is a quick-and-dirty attempt at releasing “early” — this is a small sample, and mostly drafts — I’ve already nearly 500 entries. Look at all this red ink. Crazy landscape.
  2. Still thinking about RDFa, microformats… (Exposes how Q&D I did data modeling for this. And how hard taxonomies are. ;o)
  3. Not showing timestamps per entry, yet.

Classifications

  1. My attempt at a more (semi-)structured knowledge base.
  2. Also, to normalize (standardize?) and de-hype terminology, characterizations.
  3. … turned out to be an impossible task.
  4. Recommended resources:
    1. Detailed classifications of many databases done by dbdb — are linked as canonical.
    2. CNCF SIG Storage whitepaper gives a rudimentary taxonomy.
    3. The Dictionary of Cloud-Native App Delivery

    …
