Dutch Citrix User’s Group (DuCUG) 2017 Review!
On the 3rd of November the DuCUG 2017-2 event took place with around 160 attendees and sponsors. In this blogpost you will find my experiences and my notes from the presentations.
Logically Niek Boevink started the day with an official opening. Logically Niek thanked the sponsors again for their support. With their support we can keep the event for free. Last event we raised money for the charity organization Dream4Kids and we could announce that we raid a total of 1600 Euro (with big help of PQR).
After the opening the first technical session started provided by Martjin Bosschaart and Kees Baggerman. They started with explaining the characteristics of both MCS and PVS. Kees discusses the 25-provisioning options Citrix is offering within PVS and MCS together. Next topic was that a decision tree is not workable anymore. Martijn continued with the technical fundamentals of MCS, while Kees discussed this for PVS. Next topic was RAM in cache, which is more difficult to use as memory requirements are getting higher and higher. The write cache is the most important decision topic currently according to Martijn, where he also discusses where to place the write cache in which situation for MCS. Logically Kees continued with this part for PVS. Next topic was optimization and troubleshooting, Kees started with myths and facts about PVS (PVS server virtualization, PVS stream traffic isolation, write cache placement, if/then decision matrix). Other suggestions were Citrix Supportability Pack (PXE boot check, Citrix Health Assistant). Martijn suggest to use the latest available version as both are still being developed. They ended with a nice sheet with consideration about deciding to use for MCS or PVS.
Second session was provided by Carsten Bruns with the title Citrix XenApp Disaster Recovery with NetScaler GSLB & MS Azure Site Recovery. Carsten started with the current challenges in a datacenter and continued with describing the Azure Sites and the components required for Azure Site Recovery. Carsten continued with scenarios for using Azure Site Recovery. Next topic were the supported Hypervisors and supported operating systems within Azure. Carsten continued with the technical insights and requirements, followed by the automation in recovery plans and the prices. Also some tips were shared (like the Recovery Capacity Planner, Change internal DNS zone TTL, base disks vs dynamic disks, test the failover multiple times). Citrix XenApp on Azure was next. Only working with MCS currently. No replication supported (standby environment in IaaS or replicate master image). NetScaler on Azure is nothing more than a VPX running on Azure, there are different versions and editions are available. Carsten dived into technical details like multiple network interfaces vs multiple public addresses. NetScaler GSLB components (ADNS, GSLB Site/Subnet IP, Virtual Servers) and methods were described by Carsten and showed the workflow using GSLB with an on-prem datacenter and an Azure Site Recovery.
