Message size: big or small?

January 28, 2013 at 6:15 am PST

It’s the eternal question: should I send lots and lots of small messages, or should I glump multiple small messages into a single, bigger message?

Unfortunately, the answer is: it depends.  There’s a lot of factors in play.

Citrix NetScaler VPX gets going on the Cisco 1110 Virtual Network Services platform

 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 portfolio includes two other physical appliances, MPX and SDX. The virtual VPX can also load balance across both physical and virtual servers, as well as multiple web servers, application servers and database servers.

Lowering Barriers to Hybrid Cloud Adoption – Challenges and Opportunities

Cloud computing has evolved from the hype cycle of the last few years, to being an integral part of the Enterprise IT strategy as well as a fundamental service provider offering.  The types of cloud constructs have evolved as well – public, private, hybrid and community clouds are all the basic variants, with more sophisticated application-specific cloud offerings continuing to evolve.

While the journey to the private cloud has been continuing and relatively maturing, at least in the more developed countries, and public cloud services offerings are becoming relatively ubiquitous, adoption and deployment of hybrid cloud offerings have had a relatively modest uptake.

The reason for this is not because the allure of hybrid clouds is unappealing, or that it has few use-cases. It is quite the opposite.  There are several use-cases all of which are applicable to real-world IT deployments today:

  • Workload migration:  Seamless migration of workloads from the data center or private cloud to the public cloud for better capacity utilization.
  • Dev/QA operations:  Testing of new applications can induce requirement for additional temporary capacity and having an extensible hybrid cloud is quite appealing, instead of investing in on-premise infrastructure.
  • Cloud-bursting: To handle the needs of bursty applications, temporary capacity allocation in public cloud environments can be extremely cost-effective, providing the convenience of “infrastructure-on-demand”
  • Disaster recovery: Providing data resiliency in case of failure of on-premise resources

If the use-cases are real and the benefits are so apparent, why have Enterprise not gone all out to deploy more robust hybrid clouds? Why have only few Enterprise and selective applications followed this model?

I can think of a few. To make it real, let’s consider the use-case of migrating a virtual machine (VM) from the private cloud to a provider cloud, as an example to illustrate some of the challenges:Shangri-la
