what is cloud?

cloud computing is a model for enabling convenient, on-demand network access to a shared pool of

configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be

rapidly provisioned and released with minimal management effort or service provider interaction.

cloud computing is the delivery of computing as a service rather than a product, whereby shared

resources, software, and information are provided to computers and other devices as a utility (like the

electricity grid) over a network (typically the Internet).

50 years new“If computers of the kind I have advocated become the computers of the future, then computing may someday

be organized as a public utility just as the telephone system is a public utility... The computer utility could become the basis of a new and important industry.”

— john mccarthy, 1961

why “cloud”?

demarcationseparation of duties between provider and consumer

benefitsmulti-tenancy, economy of scale » secure, reliable, scalable

tight couplinglegacy » integration

loose couplingcloud » aggregation

open sourceuses copyrights to open products

software licenseshave service provider “loophole”

close loophole?affero general public license (agpl)?

no thanks.do you really expect the source code for Gmail?

could you use/modify it if you had it?

open cloudensures openness for services

user & vendor freedomfreedom to migrate (for users)

freedom to make money (for vendors)

commoditisationundifferentiated price competition

standards create tradable commodities (GB/m, CPU/h)

standard workload?no “electron” for the cloud — 240v/50Hz is simple API

“apulettes” = code + data packets?

open formatse.g. Open Document Format (ODF)

open interfacese.g. AtomPub

open formats +open interfaces= open cloud

open standardscopyrights + patents + trademarks + open source impl.
