#in depth knowledge regarding vCenter SSO web client

Here i will tell you in depth knowledge regarding below topics.

  1. Understand the components & role of vCenter Server.
  2. Plan a vCenter Server deployment.
  3. Install & Configure a vCenter Server database.
  4. Install & Configure the Single Sign on Service.
  5. Install & Configure vCenter Server.
  6. Install & Configure vCenter Server.
  7. Install & Configure Web client Service.
  8. User vCenter Server’s Management Features.


# Understand the components & role of vCenter Server: 

Find on vCenter Page


# Centralized User Authentication Using vCenter Single Sign On (vCenter SSO):

We are discussing on users authentication to an ESXi host in the prospective of a user account created & stored locally on that host. Generally without vCenter server you would need a separate user account on each ESXi host for each administrator who needed access to the server. As the number of ESXi hosts & required administrators grows the number of accounts to manage grows exponentially. There are workarounds for this overhead that is integrating your ESXi hosts into Active Directory (AD). Administrative effort required for a small virtualized infrastructure is not a big deal or major concern. In this situations, vCenter server management might not be missed but it is very important for big infra. In addition to it’s management capabilities, vCenter can perform vMotion, Configure DRS, establish vSphere HA, use vSphere fault tolerance & these features are not accessible without vCenter server and also the key functionality such as host profiles, vSphere distributed switches, profile driven storage & vSphere update manager.

Take an example here we have 20 hosts and 10 Administrators, the administrative efforts of maintaining all these local accounts on ESXi hosts becomes difficult. In a new account is needed to create to manage these 20 hosts then you have to create that account to each host separately & if you need to change your account password then also you need to change it on 20 different hosts. Then add this equation into other VMware components such as vCloud director or vCenter orchestrator with their own possible account and passwords.

vCenter SSO ( Single Sign ON) is the exact solution for the above problem and it is prerequisite for installing vCenter server. In 5.x Version vCenter cannot be installed without installing SSO first.


# How SSP works and What other software it interacts with (Both VMware and Non-VMware):

In the earlier versions of vSphere 5.1 when you logged onto vCenter your authentication request was forwarded to either the local security authority on vCenter server OS or Active Directory. With SSO the request can still going to Active Directory but it can also go to the list of locally defined users within SSO itself or to open LDAP. SSO is attached with vCenter, vCloud Director (VCD), vCenter Orchestrator (VCO), vCloud Networking & Security (vCNS), SSO can take a single user & provide than access to everything they need through virtual infra with a single username & password & with a secured way.
