Letting Go of the 12 Behaviors Holding You Back
This post was great, thanks Mattias Tronje for sending it!
Read it and think about how you can improve!
“12 Behaviors that always hold leaders back:
- Avoiding. Avoiding is the path to mediocrity.
- Copying others and losing you. Copying others is useful when it aligns with your strengths. When it doesn’t align, it creates stress, pressure, frustration, and failure.
- Over thinking and under acting; stressing preparation over execution. Most organizations plan well and execute poorly.
- Hiding from what you really think or feel. The need to please others causes you to lose yourself.
- Asking “why” too much.”

HTML5 or Native for Mobile Apps? Try hybrid
Another interesting blog post from The HTML5 Center with some statistics from developers around their plans to adopt HTML5 for mobile apps.
HTML5 or Native for Mobile Apps? Try hybrid
What is your strategy? I guess that it’s HTML5 all the way so that you don’t have to make X number of builds for the various Android devices out there etc, but will the app perform as expected and will you be able to access all the features needed on the device, or will you revert to an hybrid or native approach like Facebook did?

NetScaler MPX vs. SDX dilemma
Hi again!
Ok, I may be totally off and wrong here but I see a bit of a problem with the Citrix product packaging and offering around the whole NetScaler product.
I love the fact that the product is available as virtual appliances (VPX) and physical appliances (MPX) and the lovely “mix-product” which is the SDX platform. The SDX is a lovely addition and I see so many reasons for why you want to go towards that platform, so bear with me.
The NetScaler product itself is a great product and the feature set it rich! It’s definitely rich in terms of what features it offers from the same appliance! Some of the marketing of the product against competitors is that you can do it all (GSLB, LB, SSL offloading, SSL VPN, Application Firewall, ICA/HDX proxy etc.) on one appliance instead of purchasing several. Have a look at the editions of the product and the rich feature offering;
But I must challenge this whole idea of putting all features/capabilities on one appliance! What if you decide to build a service on the NetScaler product and decide to provide these capabilities;
- Access Gateway
- Network Connect (SSL VPN access)
- Network Proxy (ICA/HDX proxying)
- End-to-end Web Security (AAA etc.)
- Load Balancing (LB, GSLB)
So imagine that if for some reason you need a new version of the NetScaler appliance or if Citrix provides a fix for a bug/issue that is related to one of the capabilities. Then you have to stop your whole service delivery of all of them just to apply a patch/update targeted for one of them. Is that good from an incident, problem, change management point of view? I guess that’s why I like the SDX platform where I then can put the capabilities on different VPX instances on the same SDX HW platform.
This then also leads you to the whole cost of the service if you also like this idea of separation of duties, how much does the SDX cost and what does the VPX instances cost (they are purchased in bundles of 5 where 5 is included with the SDX purchase). And except for the cost of the HW, SW and SA you have the complexity that you have to select which of the SDX platforms to choose (see a more detailed NetScaler Datasheet here). And this is the biggest issue as I see it! I’d like to recommend the SDX platform to more customers than the enterprise segment. But then you have an issue, the SDX platforms starts on the 11 500 appliance.
Why doesn’t Citrix offer the SDX model on the smaller appliances?? I’d like to understand that because I think that most customers out there will not require that much throughput or CCU etc that the 11 500 delivers….
And there are more reasons to why you would like an SDX model other than separation of duties.. but more on that in another post.
Cheers!

XenServer 6.1 Releases
“Over the past several months, literally hundreds of people have asked me the question “When will Tampa release?” I am pleased to announce that earlier today, “Tampa” officially reached GA as XenServer 6.1. Within engineering, this is officially considered a “cloud centric” release. While on the surface that would seem to indicate a lack of features for traditional server virtualization and desktop, but the reality is quite different. When you consider that a cloud runs in a datacenter, and that cloud workloads typically translate into some pretty large VM densities, all with a requirement for a high degree of workload isolation; “cloud centric” actually translates into a set of pretty stringent performance requirements. To illustrate the point, let’s consider three key features, live storage migration, network security and VM conversion.
When you look at some of the most successful clouds, you’ll quickly see that the concept of resource pools are somewhat limiting. Regardless of the size of the pool, if your cloud is successful, eventually you’re going to have more customers than can fit in your cluster or pool. During the design phase for Storage XenMotion, we accounted for this with the result being a shared nothing live storage migration solution which works equally well across all storage types and without being confined to an arbitrary resource pool concept. While designed for the cloud, it fully supports enterprise storage management requirements, and even supports live VM migration between local storage for those cases where shared storage wasn’t implemented.”
