SharePoint server reference architecture for public-facing website scenario

"Microsoft SharePoint is a Web application platform developed by Microsoft. First launched in 2001, SharePoint has historically been associated with intranet, content management and document management, but recent versions have significantly broader capabilities.
SharePoint comprises a multipurpose set of Web technologies backed by a common technical infrastructure. By default, SharePoint has a Microsoft Office-like interface, and it is closely integrated with the Office suite. The web tools are designed to be usable by non-technical users. SharePoint can be used to provide intranet portals, document & file management, collaboration, social networks, extranets, websites, enterprise search, and business intelligence. It also has system integration, process integration, and workflow automation capabilities.
Enterprise application software (e.g. ERP or CRM packages) often provide some SharePoint integration capability, and SharePoint also incorporates a complete development stack based on web technologies and standards-based APIs. As an application platform, SharePoint provides central management, governance, and security controls for implementation of these requirements. The SharePoint platform integrates directly into IIS - enabling bulk management, scaling, and provisioning of servers, as is often required by large organizations or cloud hosting providers."

The AWS architecture diagram example "SharePoint server reference architecture for public-facing website scenario" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the AWS Architecture Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Workflow diagrams" contains 54 symbol icons for drawing the work flow charts.
Use these clipart to represent information flow, automation of business processes, business process re-engineering, accounting, management, and human resources tasks in industry, business, and manufacturing.
"A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, declared as work of a person or group, an organization of staff, or one or more simple or complex mechanisms.
From a more abstract or higher-level perspective, workflow may be a view or representation of real work, thus serving as a virtual representation of actual work. The flow being described may refer to a document, service or product that is being transferred from one step to another.
Workflows may be viewed as one fundamental building block to be combined with other parts of an organisation's structure such as information silos, teams, projects, policies and hierarchies." [Workflow. Wikipedia]
