      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi&lt;/P&gt;&lt;P&gt;It should work.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;As per vCenter 5.5 Deployment guide, "&lt;EM&gt;The recommended approach for deploying vCenter Server in almost all scenarios involves a single virtual machine for the vCenter Server components and a separate virtual machine for the vCenter Server database.&lt;/EM&gt;"&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="vCenter55.png"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/52565i33A2C1C9849EA21A/image-size/large?v=v2&amp;amp;px=999" role="button" title="vCenter55.png" alt="vCenter55.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;The recommendation (soft recommendation) to centralize SSO+Web Client is when you have more than 8 vCenter servers.&lt;/P&gt;&lt;P&gt;&lt;A href="http://blogs.vmware.com/vsphere/2014/01/when-to-centralize-vcenter-single-sign-on-server-5-5.html" title="http://blogs.vmware.com/vsphere/2014/01/when-to-centralize-vcenter-single-sign-on-server-5-5.html"&gt;When to Centralize vCenter Single Sign-On Server 5.5 | VMware vSphere Blog - VMware Blogs&lt;/A&gt;&lt;/P&gt;&lt;P&gt;"&lt;EM&gt;There can be increased &lt;STRONG&gt;risk when centralizing a vCenter Single Sign-On server&lt;/STRONG&gt; (to why it is not recommended for smaller environments) due to the increased number of components affected if the vCenter Single-Sign-On server was to become unavailable, in short all vCenter Server components of all vCenter Servers registered will incur authentication loss (when compared to&amp;nbsp; just the single vCenter Server instance when installed locally) and so availability of the vCenter Single Sign-On centralized server(s) is highly recommended.&lt;/EM&gt;"&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;With single VM hosting SSO+WebClient+Inventory Service+vCenter Server. It would be easier for you to manage, backup, etc.&lt;/P&gt;&lt;P&gt;Do you have HA license in your vSphere environment?&lt;BR /&gt;HA should help you to restart SSO VM when the SSO VM dies.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
