LTKA #2: Models & Architecture:
Cloud vs. Network
- Historically, before the rise of CC, the term Cloud was very common to be used to refer to Networks or Interconnected-Systems.
- Depending on context, Cloud in this lecture may refer to both of them.
- In CC concept, Network is a part of CC, but Network is not used only for CC.
- Cloud (without “Computing”) is sometimes used interchangebly with Networks or the Internet

Data Center
- Literal: Facility to store and process data.
- A large group of networked computer servers typically used by organizations for the remote storage, processing, or distribution of large amounts of data (Google Def).
- A datacenter is a (centralized) facility, either physical or virtual, for the storage, management, and dissemination of data and information organized around a particular body of knowledge or pertaining to a particular business (techtarget.com).
- A data center is a facility that centralizes an organization’s IT operations and equipment, and where it stores, manages, and disseminates its data. Data centers house a network’s most critical systems and are vital to the continuity of daily operations (paloaltonetworks.com).
