Skype for Business Cloud Connector Infrastructure Requirements Part I


My preceding blog post discuss about different version on Cloud Connector Edition. Cloud connector edition comes with two different versions which support small to large number of calls. Single small version of cloud connector supports 50 simultaneous calls while large version supports 500 simultaneous calls.

3+1 configuration of cloud connectors provide scalability and high availability, 150 simultaneous PSTN calls can be supported in small version and 1500 simultaneous calls in large version.

Both the versions contains 4 VMs and can be downloaded from here.

    How many Public IP and Public DNS Record will require Cloud Connector Edition? In addition, what common name will be necessary to include in the public certificate?

    So it needs connectivity to a local domain controller? That is a shame for pure cloud users who only use Azure AD.

      Skype for Business Cloud Connector Edition doesn’t connect to On-premises Active Directory. While it installs its own AD services to connect with Skype for Business online infrastructure.

    RAID 0 and RAID 5 are both outdated RAID configurations, are you serious????

    This all sounds like a big MS flop!!!

      This is a requirement based on required IOPS by the Cloud Connector Edition VMs. If you want to use expensive SSD drive or 15 K RPM drives, you are free to choose. Make Sure your LUN size meet these requirements.
