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).

Connected Services - Components

  • Hardware: Devices + Infrastructure
  • Software System: Client App + Backend
  • Software System: UI + Data (Local+Remote) + Process (Local+Remote)
