內部部署和SaaS有什麽區別?



我只是好奇,內部部署和SaaS之間有什麽區別?

  • SaaS (Software as a Service), often referred to "on-demand Software", is a model where you're provided with access to the software in the cloud. There's no installation, setup or running of the setup, as the service provider will do this for you. You just have to pay the service provider. Example: Office 365
  • On-Premise is the "traditional" model where you have to install, setup and run the software at a computer at your physical location. It takes time, personnel and possible equipment. It may also have additional cost to hardware and software. Example: Office 2016

Office 365是SaaS,它提供了MS Office套件的在線版本。而Office 2016是內部部署軟件,需要安裝和運行。

此外

  • PaaS (Platform as a Service) provides a platform which typical includes operation system, databases, web server, containers for executing programming languages. Examples: Windows Azure, Azure SQL, Heroku
  • IaaS (Infrastructure as a Service), provides as name suggesting infrastructure, like virtual machines, storage, network, network service (firewalls). Examples: Windows Azure, Google Compute Engine

內部部署和SaaS通常用於定義軟件的使用方式:

  • on-premise: the software runs on some hardware which is located in your own house, building, company, etc.
  • SaaS (= short for "Software as a Service*"): the software runs somewhere (typically in "the cloud"), where you as a user of the softwre don't really know (care?) where the hardware it's running on is located.

軟件的目的是什麽,並不重要。它可以通過CRM,CMS,BI,會計......甚至是DevOps!

這與硬件的功能或運行的操作系統無關:一臺小型服務器(運行某種Linux等),一臺運行著zOS的大型主機等等。

例子

  • In the context of DevOps, let's assume you want to use GIT (and you know what GIT is used for): how are you going to make your GIT repositories available for other users to share your code. Are you going to use infrastructure (eg: some server) that you manage yourself, in your own building (= roll your own cookies), or do you rather want to "outsource" all that (e.g. because you do not have the skills or resources) and use something like GitHub?

  • Assume you want to start using "the Cloud" for sharing files, pictures, contact data, etc with other people. Are you going to use any of the available Cloud services (with all sorts of "strings attached" like fees, terms & conditions, etc.)? That would be the Saas version of it. Or do you rather want to be in full controle of it all (the server on which it is all stored/managed) and use something like (open source based) OwnCloud or NextCloud, running on a server in "your" house, building, etc. In this case "you" decide about what the terms and conditions are, and the only kind of fees you'll be facing is the cost to create and operate your own server (and manage the users allowed to access it). This is clearly the on-premise version.
