Azure Virtual Datacenter


Azure Virtual Datacenter

Sometimes Microsoft times a blog post exactly right. For a while now working on bridging worlds (on-premises / cloud) in a responsible and realistic manner. Making sure the transition is smooth and avoids pitfalls. You use what you need where you need it, when you need it and in a way that fits your needs, right? Anyway, in real life that means that I’m working on a Azure Virtual Datacenter deployment (brainstorming/architecture/design phase).

Last week during white boarding twitter notified me of the release of a new portal for the Azure Virtual Datacenter. That’s great timing! And no, there’s no need for thin foil head paranoia here. We MVP are not linked directly into the mother ship.

MSFT previously delivered an Azure Virtual Datacenter eBook with the concepts and the Lift and Shift Guide. But right now we are mainly looking at workload migrations and not lift and shift. You evaluate and make the best decision within the context at hand.

Help with project communications

The nice thing is they also published a slide deck about the Azure Virtual Datacenter concept. This helps me build presentations on this subject. Well, after removing the marketing slides and adding some extra content. Both technical content and information specific to the environments I’m working in.

Right now I’m working on the network part (VNETs, subnets, peering, BGP), but I need to pause now and go take care of some Dell PowerEdge R740 and maybe R940 server configurations to order together with some RDMA NICs. Yeah, my existing skills are still in high demand and I know how to bridge worlds pragmatically, efficiently and effectively. There is server- less in our future as well as hardware, at least for now. Now I need to get some IoT in this mix, that’s the fun full stack game right now.

Real life cost savings with Azure IAAS B-Series virtual machines

I recently move some low end virtual machines from the rather low spec but cheap basic A series (A2, 2 CPU  AMD Opteron and 3.5 GB RAM) to the newer B-Series. These have better processors and better specs all over. I did not want to move to the standard A series A2 or A2v2 as those are more expensive. I had to needs: reduce costs, get better performance. I achieved real life cost savings with Azure IAAS B-Series virtual machines

The B-Series are burstable and offer better pricing if you can build up credits when the VM is not going over it’s base line. The B-series provides you with the ability to purchase a VM size with baseline performance and the VM instance builds up credits when it is using less than its baseline. When the VM has accumulated credit, the VM can burst above the baseline using up to 100% of the vCPU when your application requires higher CPU performance. So picking the VM size is key here. The B2S seemed the best option as the base line for the CPU is 40%. and we needed at least 2 CPU and 3.5GB of RAM. The CPU type is the Intel Broadwell or Haswell E5-2673 so these are also better than the AMD Opteron.

You can see a quick price comparison here. More on the B-Series can be found here: Introducing B-Series, our new burstable VM size

One concern was that we might not be under the base line enough to build up the credits for when we go over the base line. That might kill our cost reduction hopes. That concern was invalidated by the fact that the average vCPU usage % is lower anyway due to the fact the the processors are faster and better. This helps to stay below the vCPU base line and as a result gives me credits for when I need more CPU cycles.

Overall I now have better performance at lower costs. As you can see in the screenshot of 1 VM below the savings are real after swapping over from the basic A2 to the B2S size.


So, that’s an optimization that has worked out well for me. I suggest you check it out and see where you can reduce or optimize your spending in Azure.

Cloud & Datacenter Conference Germany 2018

Cloud & Datacenter Conference Germany 2018

The Cloud & Datacenter Conference Germany 2018 is a shining beacon of light in a sea of marketing driven IT events. It is organized by Carsten Rachfahl via his company Rachfahl IT Solutions. Carsten is a Microsoft MVP and Regional Director whose commitment to excellence has show for many years in his community engagements. I think his integrity and style is a driving force behind this conferences ability to attract the quality of attendees, speakers and sponsors.


Cloud & Datacenter welcomes top expert speakers from the community and the industry. They deliver high quality sessions and share their combined experience and knowledge with attendees that are truly interested in working with those technologies. That combination delivers high value interactions and knowledge sharing. The sessions in combination with the interaction between everyone there is works very well due to the size of the conference. Its big enough to have the breath of topics needed I todays IT landscape while it is small enough to allow people to dive in deeper and discuss architecture, design, implementation and visions.

Some extra information

The Cloud & Datacenter Conference Germany 2018 is being held on May 15-16 2018 in the Congress Park Hanau, Scholes Plats 1, Hanau, 63450 Germany. That’s close to Frankfurt and as such has good travel accommodations. Topics of interest will be Azure, Azure Stack, Hybrid Cloud, Private Cloud, Software Defined Datacenter, System Center & O365. The conference is a real-life technology event so no one is pretending that the esoteric future is already here. We are working on that future by building it in our daily job and helping organizations move forward in an efficient and effective manner.

This is a great conference by technologists, for technologists. The opportunities to learn, network and exchange information are great. The speakers are approachable and all of them together are there both share and learn themselves. From my past experiences the organization outstanding and the feedback from attendees was outstanding.

I’ll be speaking on RDMA to give a roadmap on this ever more important technology. On top of that I’ll be around to discuss high availability, clustering, data protection both on premises as in (hybrid) cloud scenarios.

Do your self a favor and register for the Cloud & Datacenter Conference Germany in 2018.

All I can say is that you should really consider attending. It’s most definitely worthwhile. The quality of the attendees, the speakers and the absolute top-notch organization of the conference have been proven in the previous years. The Cloud & Datacenter Conference is a testimony to the professionalism, integrity and quality my fellow MVP and friend Carsten Rachfahl delivers with his company Rachfahl IT solution on a daily basis to his customers. So, help yourself out in your career and register right here. I hope to see you there.

Note: The CDC is German spoken conference but as some speakers are from around the globe you’ll have to listen to some of them speaking in English. If you’ve ever heard my German, I’m sure you’ll prefer me speaking English anyway.

Veeam Vanguard nominations are now open for 2018!

Just a quick blog post on the Veeam Vanguard program. The nominations for 2018 are open! That means that if you know people who would make a Veeam Vanguard you can nominate them. You can even nominate yourself, that’s perfectly fine. It’s not frowned upon, but it also doesn’t change anything in terms of evaluation for the program.


Rick blogged on this yesterday on the Veeam blog in “Veeam Vanguard nominations are now open for 2018!” and gave some more insight of what the program is, tries to achieve and does. He also discusses the selection. The key take-away is that you cannot study for this and that it is not some kind of certification or such. Some of the current Vanguards were quoted on how they look at the program and one thing is constant in that. The fact that the people in these programs are contributors to the global tech community and it’s about sharing and helping others getting the best out of their environment and their investment in Veeam. It also helps Veeam as they get a very communicative group of people to give them feedback on their offerings, both products and services. It’s just one more tool that helps them get things right of fix thing when they got it wrong. Likewise understanding Veeam and their products better for us helps us make better decisions on design, implementation and operation of them.

You can have a look at the current lineup of Veeam Vanguards over here.


You’ll find a short video on the program on that page as well. So go meet the Vanguards and find their blog, their communities and follow @VeeamVanguard and the hash tag #VeeamVanguard to see what’s going on.


So, people, this is the moment if you want to nominate someone or yourself to join the Veeam Vanguards in 2018. You have time until December 29th 2017 to do so. I have always felt honored to be selected and have found memories of the events I was able to go to and I to this day I’m happy to be active in the Veeam Vanguard ecosystem. It’s a fine group of professionals in a program of a great company.
