Microsoft SharePoint: A Comprehensive Guide

Microsoft SharePoint is a powerful tool that can help you manage and share information across your organization. It's a web-based platform that allows you to create and share documents, collaborate on projects, and communicate with your team.

SharePoint is a part of the Microsoft Office suite, and it's often used in conjunction with other Microsoft tools like Word, Excel, and PowerPoint. With SharePoint, you can store and manage your files in a centralized location, making it easier to collaborate and share information with others.

One of the key benefits of SharePoint is its ability to provide a single source of truth for your organization's information. By storing all your files and documents in one place, you can reduce the risk of information becoming outdated or lost.

There are several ways to customize SharePoint, including application-to-application integration, extensions to SharePoint functionality, web parts, and pages/sites or page/site templates.

Here are some examples of custom development methods in SharePoint:

SharePoint Designer is a semi-deprecated product that provided advanced editing capabilities for HTML/ASPX pages, but remains the primary method of editing SharePoint workflows.

It's worth noting that a significant subset of HTML editing features were removed in Designer 2013.

Microsoft recommends using PowerShell or Central Administration for configuring SharePoint's server features.

Central Administration provides access to tools such as the 'SharePoint Health Analyzer', a diagnostic health-checking tool.

This tool can help identify and fix issues with your SharePoint installation.

SharePoint's SaaS providers, including Microsoft, offer a limited subset of these features.

Keep in mind that these features are limited compared to what's available through Central Administration.

Here are some advanced features to consider:

Service applications provide granular pieces of SharePoint functionality to other web and service applications in the farm.

A service application can be turned off, exist on one server, or be load-balanced across many servers in a farm.

Service Applications are designed to have independent functionality and independent security scopes. This means each service application can be managed and secured separately from others in the farm.

Each service application, such as the User Profile Sync service, has its own specific purpose and can be used to enhance the overall SharePoint experience.

Service applications are designed to provide granular pieces of SharePoint functionality to other web and service applications in the farm.

These applications can be turned off, exist on one server, or be load-balanced across many servers in a farm, giving you flexibility in how you deploy them.

A User Profile Sync service is an example of a service application that can be used to synchronize user profiles across the farm.

Service applications are designed to have independent functionality and independent security scopes, making them a great way to manage complex SharePoint deployments.

SharePoint's architecture is designed with security in mind, featuring a 'least-privileges' execution permission model.

The SharePoint Central Administration (CA) is a web application that typically runs on a single server in the farm, but can also be deployed for redundancy to multiple servers.

In the event of the CA's failure, Windows PowerShell is used on the CA server to reconfigure the farm.

SharePoint's structure allows for multiple Web Applications (WAs) to exist on a single farm, which can be beneficial in shared hosting environments.

However, owners of these WAs may require their own management console, which is where the SharePoint 'Tenant Administration' (TA) comes in – an optional web application used to manage how a web application interacts with shared resources in the farm.
