Continue with the content of the previous chapter. This chapter mainly describes each role in the entire system in detail:
SharePoint structure:
When I was working on this project, all the system requirements were high availability, and the company's staff base was large. All servers were in a highly available structure, with a total of over 7 servers, three-tier structure. The two Web Front-end servers provide IIS services and two app servers, which are important for running various SharePoint applications and services, such as search services and user configuration synchronization services. Two database servers provide one database cluster and one independent database server provides the report service because the report service does not support clusters. For example:

Operation Manager is scom:
Scom is actually not doing well here, but I just used its monitoring function. In fact, it should be combined with SCSM to generate problem or incident events and then handled by the Response Group. Two servers are used as the Management Server and Report Server, two database servers, one ACS audit server, and one gateway server to manage DMZ servers.

Orchestrator:
The IT integrated automation core server, to put it bluntly, is the script server. All the automated tasks are handed over to it for load. You can select the number of server load based on the company's automated scripts.

Service Manager server:
SCSM is also an important part of the system. It manages various workflow nodes in all systems, stores relevant data, and provides portals for self-service employees, for example, two sm Management Servers, one of which is the management server and the other is the data warehouse server. Microsoft's SM creates a large number of Bi dimension and analysis modules, you can mine data in a workflow from various perspectives. In addition to databases, SM also needs to add the Web part of the self-service website portal on the two SharePoint servers, so it needs to be combined with the SharePoint web server.

Configuration Manager Server
SCCM manages client configurations in a unified manner and provides requirements for self-service software installation and system Redo, as well as access. The topology is not shown, the main structure is two SCCM servers. One is the management center site and the other is the main site. Connect to the Database Cluster and Report Server in the background.
Virtual Machine Manager server
The vmm server is relatively simple, mainly providing cloud platform virtualization construction. It is structured as a vmm management server, a vmm database server, and a database cluster connected to the background, my Environment manages about 10 hypter-V hosts at the same time.
APP controler is useless, because the main point is this, because Microsoft's system center products actually have their own web management interface and self-service interface, APP controler is actually a C/S client self-help software, the purpose of our internal IT unified portal is to unify all these contents through the SharePoint site and SM self-service interface, rather than using their respective systems.
DPM server.
It mainly protects the SQL database. It is actually a security layer application and has no direct interaction with our IT platform. Therefore, we will not detail it at present.
Internal IT platform structure:
Let me explain,
Level 1: access layer
For users, they all form an interface, which is our staff service self-service portal.
For IT engineers, we can use the web platform, SCSM console, and other terminals to perform operations.
Layer 2: workflow Layer
All applications, jobs, events, and so on are divided into different types of work flows. The approval process is subject to approval, and should be activated automatically, and the automatic script should be activated. In this example, the orchestrator Automation server is used to call interfaces of other applications. For example, to activate a VPN, you need to add it to a security group in the domain. orchestrator will call the ad module, apply for an office 2013 installation, and orchestrator will call the interfaces in SCCM to push the software.
Layer 3: Data Layer
Archive, back up, update knowledge base, and collect data for data mining.
