#Citrix and Palo Alto Networks Team to Deliver Consolidated, Multi-tenant Network Security and #ADC Services on #NetScaler SDX
This is really interesting!!
With the myriad of features that we launched in PAN-OS 6.0, you may have missed a new deployment option for Palo Alto Networks VM-Series in your data center. In addition to the support of VM-Series for VMware environments, you can now deploy the VM-Series on the Citrix NetScaler SDX platform. We launched this with Citrix officially today.
Virtualized and cloud environments require the secure and efficient delivery of the right applications to the right users using any device and from any location. To do this, you need an infrastructure that supports all aspects of application delivery (security, availability, performance and visibility) and embraces the key characteristics of cloud:
- Multi-tenancy – the ability to support differing needs of new application owners, business units or service provider customers
- Agility – the services must have the ability to be provisioned and de-provisioned on demand, with support for automation and orchestration
- Scalability – the services must have the ability to flexibly scale up, scale out capacity to meet the needs of the business
Citrix NetScaler SDX is an open, multi-services platform that addresses these requirements. The NetScaler SDX platform consolidates NetScaler application delivery controller (ADC), and best-in-class network and security services required for application delivery. Now, with the introduction of VM-Series on Citrix NetScaler, you’ll be able to provide dedicated instances of security and ADC for per application load balancing with dedicated firewalling. You now also have a complete, integrated security and availability solution for Citrix XenApp XenDesktop deployments – from secure remote access, high-availability…

#Citrix #NetScaler Traffic Domains ins and outs – via @barryschiffer
Another great blog post by Barry!!! Keep up the great work!!
Citrix NetScaler Traffic Domains are a way of segmenting network traffic for different applications or even tenants. You are able to use a traffic domain to create fully isolated network environments on a single NetScaler instance. An instance is a single appliance or a HA setup of two appliances.
Citrix NetScaler Traffic Domains were introduced with NetScaler 10.0. At first NetScaler Traffic Domains started as a somewhat hidden feature which you could only configure by CLI. As of version 10.1 Traffic Domains are fully configurable in the NetScaler GUI which makes it a lot simpler to use.
In a way NetScaler Traffic Domains could compete with the NetScaler SDX platform. With Traffic Domains we segment networks on a single NetScaler instance instead of the SDX where we create a virtual appliance per network segment.
A downside of using NetScaler Traffic Domains is the fact that some features are only supported for usage inside of Traffic Domain 0. Traffic Domain 0 is the default Traffic Domain, all services run inside Traffic Domain 0 unless explicitly specified.
An example of non supported features are NetScaler Management and NetScaler Gateway. For a complete list of supported features follow this link.
For non supported features for which you need isolation you have two options, NetScaler SDX or additional NetScaler appliances (virtual or physical).
My expectations are that we will see more and more features being supported on NetScaler Traffic Domains. An amazing feature would be to enable management functionality on Traffic Domains where you would only be able to manage or create services assigned to that Traffic Domain. This would be especially useful for multi-tenancy or multi management in situations where for example one team manages Mobility and one team managing a web application.
A few use cases Citrix describes for NetScaler Traffic Domains:
- Use of duplicate IP addresses
- Use of duplicate NetScaler entities
- Multi Tenancy
A use case I’m actually using NetScaler Traffic Domains for is the ability to deliver services in a DMZ as well as an internal network.
Internal Network services like Microsoft Exchange Client Access Services and Microsoft App-V are heavy on traffic and I don’t like those services traversing the firewall in the DMZ. This also works great combined with Direct Server Return (DSR) which is blocked by most firewalls. Check out more on DSR combined with App-V on this article by Ingmar Verheij.
#Citrix #XenDesktop 7 on #vSphere Validated Design Guide is available now!
Really good design guide by Citrix and blog post by Carisa Powell:
We are pleased to announce the availability of the Citrix Solutions Lab 5000-user XenDesktop 7 on vSphere Validated Design Guide.
Yes, you read that right, XenDesktop on vSphere. XenDesktop is also known to many vSphere customers as the best VDI solution for vSphere, and this design guide showcases the latest release of XenDesktop features and functionality all being hosted on a vSphere hypervisor. XenDesktop is the best of both virtual apps and desktops from a single platform, so XenDesktop is VDI, XenDesktop is app virtualization, XenDesktop is server-hosted apps and desktops, XenDesktop is secure remote access, XenDesktop is mobility…and with XenDesktop 7 you get all of this functionality from a single platform.
This design guide combines everything that is XenDesktop 7 and delivers it from vSphere to showcase how you can provide an app, desktop, remote access, and more solution for any type of user:
- VDI – XenDesktop offers a variety of VDI use cases, whether the user needs a standardized, corporate desktop that remains consistent and routine, or the user needs a personalized virtual desktop that he or she can customize to meet their business needs. This design guide validates XenDesktop Provisioning Services central image management technology for Pooled VDI on vSphere and XenDesktop Personal vDisk technology for delivering Personal VDI on vSphere.
- Server-hosted Apps and Desktops – XenDesktop also offers server-hosted apps and desktops by leveraging Microsoft Remote Desktop Shared Hosted (RDSH) technology to enable multiple users to connect and share resources from a single server. This design guide showcases XenDesktop server-hosted resources from Windows Servers on vSphere.
- Remote Access – XenDesktop leverages Citrix NetScaler appliances to provide secure, remote access from any location. NetScaler can be a virtual or physical appliance, and this design guide highlights the implementation and configurations of NetScaler Gateway virtual appliances on vSphere.
So why showcase all the features and functionality of XenDesktop 7 on vSphere? Staying true to the Citrix vision, XenDesktop continues to remain the only hypervisor agnostic app and desktop virtualization solution – including VDI, virtual apps and more. This means XenDesktop 7 seamlessly integrates with any hypervisor including Microsoft Hyper-V, Citrix…

Choose your #Citrix #NetScaler … wisely… – via @hlouwers
This is a question I get a lot and I must say that Henny Louwers did answer it well in this blog post!
I spend a lot of my time breaking down the different models of Citrix NetScaler appliances and different Software Editions within the Citrix NetScaler portfolio.
I decided to set up a blog about this since the path is usually pretty much (lengthy but) the same. This does not mean the answer is always easy because there are a lot of questions that need to be answered.
The first thing I would like to get off my chest is the following: Stop seeing/selling the Citrix NetScaler as a replacement for Secure Gateway. It is so much more than that. I often have discussions with various engineers and consultants telling me that Citrix NetScaler is so expensive for a Remote Access solution because Secure Gateway always used to be free. No offense but a Citrix NetScaler solution belongs to the networking department, not the Citrix XenApp sys admin department. Or maybe limited.
That leads me to the first difficult thing of a Citrix NetScaler project. The adoption of the Citrix NetScaler appliances to the networking guys of an organization. They need to embrace the solution to make this a success. For some reason they too see it as a ‘’Citrix’’ solution. For that reason one of the most important meetings to setup is usually with the networking guys to try to explain the L3-L7 functionality of the Citrix NetScaler solution. When they realize it competes with F5, Juniper, Cisco, etc then we are on the right track.
NetScaler Gateway or NetScaler Standard Edition
Usually the first question of a customer is regarding something simple like replacing the Remote Access solution. Since the NetScaler is going to be the main platform for publishing Citrix publications a NetScaler Gateway can be considered as a valid option. This is when I tell a customer it would be wise to spend a little extra on the NetScaler Standard Edition since this would leverage the solution be having full load balancing capabilities (among others). When you compare prices between the NetScaler Gateway and NetScaler Standard Edition you will see that the Standard Edition will be somewhat more expensive but I for one think that it is worth the difference given the feature set that come with the Standard Edition. Of course the NetScaler Gateway can always be upgraded to a NetScaler Standard Edition (or higher) if you will.
Another feature of Citrix NetScaler Standard Edition is the ability to run Citrix Web Interface on the appliance. Honestly, I do think is not really that important anymore….

#Citrix #NetScaler VPX on the #Cisco 1110 Virtual Network Services platform – via @pigram86
Interesting!!! 🙂
This week at Cisco live! in London, Citrix is demonstrating the Citrix NetScaler VPX virtual application delivery controller (vADC) on the Nexus 1110 Cloud Services Platform . NetScaler VPX is the industry-leading vADC and is further testimony to the expanding ecosystem for the Cisco Nexus 1000V virtual networking portfolio and the Cloud Network Services platform. The integrated Cisco-Citrix solution follows on the heels of last year’s agreement by the two companies that Cisco would reference sell the Citrix NetScaler portfolio, and Cisco’s demonstration of its Nexus 1000V virtual networking portfolio on Citrix XenServer.
The Nexus 1110 is the latest generation of appliances that started with the Nexus 1010. The Nexus 1110 helps customers that are virtualizing more of their application and security services and want to run them on a dedicated platform. For example, virtual firewalls, like our Virtual Security Gateway (VSG), complement physical firewall appliances to support virtual application deployments and VM mobility requirements. The Nexus 1110 appliance serves that need, running a range of virtual services on a platform that the networking and security teams can more directly control than the other application servers.
With Citrix NetScaler VPX integrated into the Nexus 1110 Cloud Services Platform, enterprise IT admins can scale-out deployments by enabling additional virtual NetScaler instances (VM’s) directly from the Nexus 1110. NetScaler VPX also provides feature and management consistency across physical and virtual ADC’s, as well as consistency across physical and virtual workloads that are being managed. The NetScaler…
