2009-2011

The major advantage in attending a technical conference (beside of networking aspects) is improving your own experience based on real-world feedback and learning from others' validated best practices. It's also interesting to compare different international approaches on solution design. This applies to vendor-independent events, especially.
Over the course of time I became a speaker, too. I held more than 20 international presentations across major worldwide events specific to application delivery industry and an almost uncountable number of regional public and non-public presentations for both customers and a broader public audience (beside of "classic" individual consulting); find a reference below.

If you're about to host a conference falling into my primary disciplines like virtualization technologies (applications, servers, VDI, etc.), enhanced networking solutions or overall IT architecture innovation, just let me know if we could join.

My references

Based on my project history and my ongoing participation in application delivery community I already was invited to present some of my technology favorites in public:

As a part of my primary job role being an IT-Architect, I'm also hosting technology sessions and product reviews. Those are directly aligned along current product launches and vendor activities:

Citrix Provisioning Services - surviving demanding customers
With the world moving towards dynamic data centers, many reasons exist for using Provisioning Server to deploy XenApp workloads. In some environments, this is easily accomplished with a straightforward implementation without too much thought or experience, but when companies or clients require baseline metrics based on service-level agreements, enterprise dependencies, throughput limits, or use density, things can get quite complicated. Since Citrix Provisioning Server relies on I/O strategies, proper system sizing and deep implementation design are crucial aspects to the success of the project from an end-user, systems administration, and management perspective.

In my session I outlined high availability and write-cache strategies for XenApp in enterprise environments. I also covered how to customize applications at boot time and how to ensure XenApp application publishing remains bullet-proof and reliable when server footprint is dynamic and the workload is unpredictable.

This presentation has been (statistically) ranked place no. 1 on this BriForum with a score of 4.98 out of 5.00 points. I'd like to say thank you to all attendees for their ongoing support!
Citrix Provisioning Services - surviving demanding customers
High availability guarantees enterprise uptime - do you really need a Citrix NetScaler?
Centralizing access by means of Terminal services and VDI requires the infrastructure to be as reliable and as fault-tolerant as possible. The Citrix Delivery Center has become a complex set of interacting products; its individual points of failure have increased and need to be analyzed properly as they typically impact user experience. Does it really make a difference to use load balancing hardware solutions instead of classic DNS-based, NLB-based or proprietary fault-tolerance configurations? Does Citrix NetScaler behave different than other solutions or does it matter at all?

This session showed some 'lessons learned' while doing customer-driven HA-projects in the wild, and outlined the respective tasks and advantages of having a vendor-agnostic solution. I also reviewed the upcoming virtual NetScaler (VPX) technology.

net.workers deployment toolkit: workload setup and configuration
A server setup done at high quality is the key foundation for later productive user loads. The required amount of work and needed budget associated with that often prevents such detailed deployments but overall no serious alternate solution exists. Within my presentation I showed how to achieve the goal having highly professional setups by using built-in operating system tools and thus effectively limiting the deployment costs.

Citrix Provisioning services: Workload streaming in XenApp-environments
Workload streaming (in terms of a fully-configured operating system) is a new concept to provide datacenter dynamics regarding server system reconfiguration. Especially Citrix XenApp highly benefits having such an infrastructure in place, for example assigning new workload versions (upgrades/downgrades) or rescaling silo capacities. My demo outlined the interleaving between Provisioning services and server virtualization which establishes a dynamic application provisioning environment.

About BriForum

A few years ago, Brian Madden introduced an innovative conference concept called BriForum which covers all aspects on server-based-computing. In contrast to well-known other events, the BriForum is focussed on pure high-level session content targeted to a technical audience like system-engineers, administrators and architects. Nagging the guests with marketing stuff is strictly forbidden and if a speaker misbehaves to this housekeeping rule, all attendees proceeded with other sessions and leave the room.

The presenters enjoy this kind of atmosphere which allowes offering in-depth lectures around many aspects of terminalservices computing and requirements of technology usage to a very skilled and demanding audience (difficulty and expectations may be compared to MS-Level 400).
