Database design is an integral part of every Citrix product's architecture design. XenApp is also dependent on it to store its configuration settings and runtime or change log data. Therefore, its design best practices and recommendations taught in Citrix XenApp 6.5 Training prove to be an essential guide for users who have to make such critical decisions. Users need to ask the following questions and take a decision based on their specific needs.
• Version and Vendor – A whole lot of software vendors are offering database platforms for enterprise use, but you need to decide which vendor does your Citrix deployment support?
• Log Sizing – Depending on the number of users, you need to ascertain whether an environment for that number of users needs a larger storage? Also plan about the Configuration Log DB.
• DB Edition – Decide on what edition you wish to go for - Enterprise, Datacenter, Workgroup , Standard, Web or Express?
• SQL Server Sizing – Ascertain whether your configuration (e.g. 2 cores and 4 GB RAM) is enough for an SQL server to host XenApp? Also find out whether an increase in number of users will have adverse impact on performance at a later stage?
• Authentication and Authorization – Will you go for SQL authentication or Windows authentication? Have you decided on the minimum permission criteria required to perform normal operations?
• High-Availability – Would you rather go for Clustering, Mirroring, or VM-level High Availability?
Once you're able to answer all these questions successfully, you are much closer to choosing the optimal database for your Citrix desktop application delivery deployment.
