We are discussing some of the details of this architecture in later sections of this document, though you can immediately notice the similarities to the much simpler greenfield/cloud only deployment model: Diagram 1: 100% Customer Managed, Lift/Shift deployment using AWS as IaaS only. This also allows us to describe the AWS platform in terms that are familiar to most IT professionals. When running a fleet of VDAs on AWS, choosing the right instance type for your different workloads (VDAs) is a key decision, with substantial performance, manageability, and cost considerations. the Machine Catalog creation wizard in Studio (either CVAD or CVADS). Combined with the ability to pay for resources as you consume them and simply remove them when you’re done? For more information on Citrix App Layering, refer to the product documentation and App Layering reference architecture. This highlights one of the other benefits of moving to public cloud infrastructure on AWS: you continue to benefit from the investments they’re making (on a scale well beyond the reach of most IT organizations or even governments) over time. Customers can manage their own highly available DFS file share, benefit from this as an AWS service (FSx) to save on management effort, or use third party storage appliance solutions to extend on an on-premises environment. This can be accomplished by provisioning FSx managed file systems in multiple availability zones, and using Windows DFS-N/DFS-R to create highly available Windows file shares, though it’s easy to end up in an unsupported configuration (per Microsoft) if you’re not careful. In Diagram 15, CitrixResourceLocationStack is ‘on top’, and the other three stacks nested underneath it are foundational stacks, managed and maintained by AWS. A XenDesktop and XenApp solution can take on many delivery forms. In these instances, we recommend working with your Citrix partner/sales/engineering team to help overcome them. 469 0 obj Solution options encompass a combination of solution models including local disks, iSCSI or Fiber Channel based storage options. For use cases/environments where the cloud service doesn’t meet your needs, customer managed components can be used. The Citrix architectural design framework is based on a unified and standardized layer model. As customers plan to migrate workloads to a cloud platform such as AWS, they must ensure that app performance is not impacted. desktop transformation 437 0 obj Remove any accounts that no longer require these administrative rights.
