- Features that are under considerationThese are the features that are top of mind for us for future deliveryThese are subject to change
- It works by combining a comprehensive centralized management system with a Type-1 client hypervisor.
- The foundation of the solution oriented thinking is based on our 5-layer model. The User Layer defines the user requirements. Each group of users will have requirements specific to them. What are they? The access layer helps us understand how users will gain access to the environment, which is really trying to determine how users will gain access to their resources. The resource layer defines those resources. What applications and desktop will the user receiveOnce the top 3 layers are complete for each user group, we then start developing the underlying infrastructure. One infrastructure to support everythingWe start with the control layer that maintains the environment for us. It makes sure the resources are ready, the policies are in place and proper security is being administered. Ad finally, we end up with the hardware layer, which is the physical implementation of the overall solution
- Desktop lock makes things seamless. Logon like normalWhen logon successful, instead of seeing local desktop, you get your virtual desktopUsers are not able to get to the local desktop. Only an admin logon will work
- Most important diagram – Storefront Services is intended to be a single (logical) aggregation point that serves all users regardless of which device they are using and whether they are local or remote. The system has intelligence to determine and understand the context for each request and act accordingly.For instance, remote requests coming through AG will then launch ICA connections through AG automatically.
- In many env, It sets up failover via DNS round robin, which does load balance requestsThis solution, and so many other Lbing solutions lack intelligence to dig deeper to see if services really available. Most just look to see if server is on the network with simple Ping. What happens is that if a service fails, users will get sporadic failures as the request gets LB’ed to the failed service
- VPX Express (free) / VPX 10 (2.000USD)With automated failover using NetScaler VPX Express, we test to see if the service is active in addition to the server. That means it checks to see if SF is accessible and if DC is responding to requestsIf a service is down, it is automatically taken out of rotation until it starts responding againThe build in wizards makes this easy so you don’t have to be a networking genius to get it done
- But simply gaining access isn’t enough. We need to make sure that the pathway we take is the most optimal. Take the following examples with regards to HDX Optimized Routing:Without optimization, our user will be load balanced to one data center. Their authentication, enumeration and application access network path will go through the first data center even though the resource they are trying to access is in data center B. Not optimal. A better way, with optimization is to redirect the user’s application access network pathway to the gateway that is in the same data center as the app. So even though the authentication traffic (red line) goes through data center A, the ICA or HDX Traffic (green line) goes through data center B, which is a more direct network pathway
- Mobile users are mobile, which means they might try to access the XenApp hosted app from an external location, an internal location and even from behind a paywall (internet cafés or hotels). However, many organizations do not allow internal people from accessing resources located within the DMZ, as DMZ resources are typically meant to be accessed by external users only. We don’t want users to have to re-configure their endpoint device whenever they come to the office. Imagine the number of support calls!Instead, we deploy Beacons within StoreFront. Beacons (web sites) identify whether a user is connected to an internal or external network. Internal users are connected directly to resources while external users are connected via Citrix NetScaler Gateway. Citrix Receiver continuously monitors the status of network connections (e.g. link up / link down or change of the default gateway). When a status change is detected, Citrix Receiver will first check that the internal beacon points can be accessed before moving on to check the accessibility of external beacon points. StoreFront provides Citrix Receiver with the http addresses of the beacon points during the initial connection process and provides updates as necessary. It basically works like thisIf I can only access the external beacon, I will use the Gateway Connect methodIf I can access the internal AND external beacons, I will use Direct Connect methodIf I can NOT access either external or internal, then my Internet connection is blocked and I won’t try to make a connection
- Enables end users to: Launch local applications using shortcuts embedded in their virtual desktopSwitch between local and remote application windows all within the virtual desktopLeverage task bar integration features like minimizing, maximizing and groupingAutomatically launch local applications based on the appropriate file type associations configured by the administrator (in Highly Managed mode) Cutand paste between local and remote applicationsEnable administrators to: Publish locally installed end point applications to their virtual desktop usersControl URL redirection to choose either the local internet explorer or the remote internet explorer
- Here’s an example where the user has iTunes installed locally and it is integrated into the user’s virtual desktop via Local App Access. It appears in the task bar.
- Key points:Next generation Director rearchitected on the XD 7 platformUnified console provides the real-time troubleshooting along with integration of new EdgeSight features, Performance Manager and Network InspectorScales with the platformMost common problem – “I can’t connect” Instrumented XD to provide various failure causes for connection and machine failures to determine root causeEnd user experience starts with logonDirector breaks the logon into each of the steps, providing the analysis so the admin is able to pinpoint exactly where the slowdown is occurring
