Here’s a quick overview of my speaking engagements in the next two months. I encourage everyone to attend the smaller and often les expensive or even free events as they provide a fast way to get up to speed with new technologies. Don’t be shy. Everyone is welcome and we’re all there to learn. It will not surprise you that all the sessions I’ll be presenting are on Windows Server 2012 & Hyper-V.

Experts2Experts Virtualization Conference (E2EVC) –Vienna 2012

I’ll be doing a session on Saturday 26th on the advanced networking features in Windows Server 2012 Hyper-V. At this small scale conference interactive “chalk & talk” sessions never stop. They just go on and on at breakfast, lunch, dinner, the bar until we need to get some sleep to repeat this process the day after. If you’re very lucky there might still be an spot open for which you can register.

Continued Education Day for IT Coordinators & Teachers in Education

At the end of May I’ll be presenting a session on what’s new in Windows Server 2012 Hyper-V targeted at this audience. I’m convinced that the combination of the tremendous licensing efforts Microsoft does in education and simply the best virtualization & cloud platform in existence, will provide them with the right solution to get the job done.

TechNet BeLux – Experience Days

On June 7th I’ll be presenting a session at the “Experience Days”. That session is called “Windows Server 2012 Storage Evolved For Hyper-V” in the Experience Windows Server 2012 track. You can register here for this track or, if you think another track is more of interest to you go to the links above to register for those. All tracks are free and open to all.

More to come

During the summer I’ll be doing a large storage migration project. That means I’ll be getting my hands on SMI-S support for System Center Virtual Machine Manager 2012 and ODX to use with Windows Sever 2012 & Hyper-V.  So I’ll be putting my money where my mouth is so to speak.  I’m looking forward to that for the learning experience alone and it’s time to find me my “No, I will not fix your computer” T-shirt as I won’t have time for that Smile. But rest assured, I will share my experiences through blogging, tweets, presentations & with my fellow community members for all man kind.

My Best of MMS 2012 Series: Private Cloud 2012 Lessons Learned from Our Early Adopters

An open discussion on people who have built private clouds at customers.

Elasticity

In real live things don’t shrink that often.  Smile Free or real cheap back charge rates are not doing anything to help.

My take on this is that you should look at elasticity as a flexibility feature. Even if a cloud is no that elastic in both ways. You can shrink a cloud v1 to zero as you migrate the VMs to private cloud v2. Than dump the resources back into another pool, step by step or in one go. I’ll use whatever works to make my live easier.

Standardizing & Customer Centric Operations = Planning is Key!

These two can be hard to combine. It takes serious planning and as such an upfront investment.

Than you need to build it to optimize operations (cost & excellent service). This sounds nice but how good are we at this and what is the shelf life of a solution versus the investment?

There is a lot of preparation to do. There is a lot of things to consider. Databases, Storage, the network, security boundaries, disaster recovery planning. They advise not to do it cross domain. Hmmm … we need to address this. Seriously..

Testing => build decent scripts with variables & config files. This will help to deploy in test, acceptance & production without to many changes/work.

Make sure you define all service accounts, groups and permissions you need.

It’s all about planning and what’s being told are best practices that exist already, private cloud or not.

Self Service

  • Service Catalog is a prerequisite.
  • Self Service is key to the private cloud.
  • If people can they will do things differently. You’ll have to learn to deal with this.
  • Billing for services should be clear. Not to much detail. VMs & Storage are two good ones. Keep it simple and don’t go into memory & vCPU. Just set boundaries.

Demos

We dive into the System Center products and look at it from both the IT Pro and the consumer side of things.

Requests => Approval & Deployment

Approval process should be dynamic based on what is requested & who’s making is. You’ll also need SLAs & chargeback on these. Be careful not over complicating it or you encourage rogue IT.

RANT: IT should make things as easy as possible. And in this discussion I’m not won over for charge back. It often turns into an excel exercise. Internal IT becomes more and more like an external service provider or integrator in this model. The inherent strength of being part of the business and being in the best position to help that business move ahead is lost. Is this a complot of the integrators? It fits their model but basically a lot of that is broken very badly. The last thing internal IT should do is become like them. That will do nothing for “Business-IT alignment”. We need to leverage the possibilities of the private cloud for our business or we have no unique selling point. Not that the service providers do a better job, but at least they are not on the pay roll so the bean counters like that. And as long as they can use public cloud to get their needs served hey couldn’t care less about who does the private cloud thingy for them. So a functional IT is first and foremost what we need. That is customer centered. Alignment of business & IT is worthless without that. The latter happens ay to much.

Management

Well yes this is important. We need reports, reviews, Service Improvement Plans, look for opportunities for automation.

I’m off to Attend MMS 2012 In Las Vegas

Life is good people. I have to good fortune to work in an interesting industry, doing great projects with modern technologies. On top of that my employer allows me to fully develop my skills . In that respect it makes a serious difference to have a good boss & management that understands the benefits of ongoing education. They look a both the short & long term value of people educating & developing themselves a lot more than at that nagging Excel sheet on the screen. Professional development is not just a cookie cutter 4 day training course once or twice a year but real opportunities to become a better professional if and when you’re willing to put in the effort. They’ve figured out that you cannot just use utmost cost reduction to catapult both your business and employees in to prosperity & wellbeing. You need to keep learning, evolving, networking, … The contacts I make and the education I get by working with and learning along very smart & motived people are priceless. Sure it costs money and effort form everyone involved but it beats doing nothing and saving a few € as a long term strategy for growth & success. On top of that I feel appreciated & valued for my contributions and the efforts I put in.So to the tunes of some eighties rockers I’m off again.

Here I go again on my own, goin’ down the only road I’ve ever known.
Like a drifter I was born to walk alone. An’ I’ve made up my mind, I ain’t wasting no more time. I’m attending MMS 2012

Alone, heck no, many thousands of us will be descending on Las Vegas (Nevada, USA) to attend the summit. This event sells out fast each year. A friend told me to register a.s.a.p. or miss out, so I did as soon as I got the go ahead to attend, securing my spot. So now I’m travelling over LHR to LAS following my buddies & other attendees journey from their respective countries to Las Vegas on line, mostly via Twitter.

If you can’t come, whatever the reason, you can always enjoy a good number of sessions here MMS 2012 goes digital: LIVE streaming and On-Demand for attendees AND non-attendees! 48 hours after the live presentation.

I don’t have to tell you what System Center 2012 means to the IT Pro in the Microsoft ecosystem. Combine that with the RTM of Windows 8 later this year and I just had to go and attend the Microsoft management Summit 2012 in Las Vegas.  It’s more than training. It’s networking and an education.

Apart from the formal agenda & sessions I already a have some meetings lined up with vendors, colleagues from around the globe. We’re making the most of this opportunity to meet face to face with people we other wise only get to talk to on line and often with huge time zone difference.

MMS2012_Server

I’ve you’re going and you read my blog or follow me on twitter. Give us a shout out and perhaps we can have a meet & greet.

To all my geek & nerd friends, colleagues, MEET members, business partners, Microsoft employees & MVPs in route to Vegas & the Summit at The Venetian, I’m looking forward to seeing you all again! But first I have some traveling to do in the next 24 hours, to make my way over there.

Don’t Be Afraid To Learn PowerShell, You’ll Need It & You’ll Learn To Love It!

Posted on by

As I started my career in IT doing data crunching, OLAP & development in VBA & VB5.00/6.0 it isn’t that surprising I’ve done most of my automation in VBScript. I’m very familiar with it and even in the Windows 2008 Core era it was very useful as we didn’t have .NET in it at that time, meaning no PowerShell (no, the unsupported hack to get it on there does not count).

The first real PowerShell use for me came with Exchange 2007. That worked out pretty well, but at the time we didn’t use it for much more than Exchange. Today, more and more I’m starting to use PowerShell versus VBScript. For one sometimes VBScript can’t get it done, it’s not being developed any more in its capabilities and two, PowerShell commandlets do pack a serious punch!

Since Windows Server 2008 R2 PowerShell has gotten better overall support and with Windows 8 it is everywhere, natively. That’s very good and it means we can do all we need to do now (well a whole lot of it) in PowerShell. And then I haven’t even mentioned the entire workflow support in Windows 8 PowerShell!  As an old VB guy I had to get over my dislike for curly braces. I also need to earn the different syntax and especially the way in which to use the programming constructs (control flow, sub routines, operators, data types).

A lot of people tend to focus on the one liners. These are great and powerful, but they often reminded me of the old discussion with C/C++ developers about code readability & maintainability.  For that purpose we don’t mind that the code is more verbose. One liners are not the goal  but they are fun. Just remember that all code, how small it may be, one day will have to be maintained. The more readable, logical and easy to understand it is, the better. The whole “self documenting” thingy Smile.  One liners do not always fit in here. But to demonstrate I have nothing against them I’ll show you a real easy example for all you out there dealing with the jump to PowerShell. If you get hooked on one liners just be sure to use them with reason and go visit the blog of Jeff Wouters , you’ll become good scripting buddies.

Let’s say in VBScript you needed to format a date in a specific way. In VBScript you have a very limited number of format option to use. So when you want something funky like “20120414” (YearMonthDay) as a date format you’d use a function that builds that string and pads the numbers with zero if needed. You can either write a generic function to handle all possible date needs or a custom/purpose built one for just the needs at hand.

Just to get the gist of this, it could look a bit like this:

WScript.echo FormatDateForMyNeed() PrivateFunction FormatDateForMyNeed () Dim sDate, sYear, sMonth, sDay sDate =Now() sYear =Year(sDate) sMonth =Month(sDate) IfLen(sMonth) =1Then sMonth ="0"& sMonth sDay =Day(sDate) IfLen (sDay) =1Then sDay ="0"& sDay FormatDateForMyNeed = sYear & sMonth & sDay End Function

Driven by “routine” & a VBScript background you could mash up some functions in PowerShell and make it a convoluted scripting exercise:

function BuildDate { $date=Get-Date $String= [string]$date.year $MONTH= [String]$date.month $String+= PadString "0"2$Month$DAY= [String]$date.day $String+= PadString "0"2$DAYReturn$String } function PadString ($PadChar, $PaddedLength, [String]$StringToPad) { $StringToPad= ($padChar* ($PaddedLength-$stringToPad.length)) +$stringToPadReturn$StringToPad } BuildDate

But PowerShell has way better date format support than VBScript and you can just write this:

Get-Date -format "yyyyMMdd"

Now that’s a one liner I have nothing against and yes, it saves a whole lot of effort. Sure this is a real simple example but it proves a point. Do your self a favor, take out a couple of hours a week and dabble around in PowerShell. You’ll add a valuable time saving tool to your inventory and gain a precious skillset Smile for a bright future! Need a good example? See this blog post by Janssen Jones to see some workflow goodness and what it can do.
