Lots Of Upcoming Training and Speaking – Come See Me!

Happy Thursday, everyone! If you haven’t noticed, I have been pretty silent on the blog front. I am heads down writing the book (which is coming along nicely) as well as doing customer work. Fingers crossed, the book will be done before Summit. I will get back to a more normal blogging schedule when the book is done. Also, be sure to check out Max’s blog posts as he is now also regularly blogging here on the site.

It hasn’t been all book writing and customer work, though. Today I updated our Training and Events section with lots of new stuff. I am pretty excited, but it also means that I will be on the road from late September until early December. The things I do for you guys 🙂

First up is my 4-day Mission Critical SQL Server class in London via Technitrain from September 28 – October 1. As with all my 4-day deliveries, there are lots of hands on labs (bring your own device, though!). This has been on the books for quite some time. I love London, and my class in 2014 was a blast. I expect this delivery and the students to be the same. I may also be doing something else that week … stay tuned!

I will only be home a few days before heading down to Orlando (a place I *clearly* hate if you know me at all – Disney here I come!) for SQL Saturday 442. On Thursday, October 8, I will be doing a brand new preconference session entitled “Planning Highly Available SQL Server Deployments in a Cloudy, Virtualized World“. This is a “normal” precon, meaning there are no labs like some of my other precons. This helps to keep the price down while I get to deliver a really fun – and timely – topic. On the Saturday of the event, I will be delivering the talk What’s New for High Availability in SQL Server 2016 and Windows Server 2016 – another new one I am putting together.

The next thing on the books is the big kahuna – PASS Summit 2015. I am honored to once again be doing a preconference before Summit. This year I will be delivering “Advanced SQL Server Availability Architectures and Deployments“. I could have done the safe thing and just submitted an updated version of what I did last year. Why rest on your laurels? Don’t get me wrong – having 100 people doing labs at the same time was amazing, but been, there, done that. How could I kick it up a notch? Do something more difficult! Everyone gets their own lab environment (i.e. multiple VMs) that they connect to via a browser pm a device they bring with them. I am finalizing what the labs look like right now and will be building the VMs in the next month. I truly believe for topics like this you need to touch and feel. No hands on makes advanced topics more difficult to learn. Space is limited and I expect another sold out session, so register early. Don’t miss the PASS Summit 2015 Speaker Q&A I did for the precon posted up at the Summit site.

During Summit, I was asked to participate in the panel discussion “Will the DBA Job of the Future Still Involve DBAs?“. That should be a lively panel. For the third year in a row, SQLHA will have a booth (this year once again with Denny Cherry & Associates) called Consultant’s Corner. Drop by to say hello to Max or myself – we’ll both be there. Unlike last year where I was juggling speaking as well as the MVP Summit over in Redmond, I will be in the booth quite a bit this year.

Finally, I am very excited to be returning to Australia for two weeks. The last time I was there was 2013. WardyIT is once again bringing me back as part of their Platinum Training series. I will be delivering my 4-day Mission Critical SQL Server Workshop in Brisbane (November 24 – 27) and Canberra (November 30 – December 3). Every time I go to Australia it is two different cities; the last time I did this combination was in 2012. The last time I was in Brisbane I also spoke at the user group, so we’ll see what happens.

As an aside, both the London and Australia deliveries of the Mission Critical SQL Server class will also be the first time that I will be rolling in some 2016 (both SQL Server and Windows Server) content formally into the curriculm where it is appropriate. My classes are always evolving.

Whew! Are you tired from looking at my schedule yet? I know I’ll be hitting at least Platinum on American with all of those miles in the air. And if all of this was not enough, there are a few other things in the works which are not quite ready to be announced yet. As soon as they are, they will be on the events page.

Defending Fort SQL Server

I’m seeing a common theme with a subset of our customers. It goes something like this: An enemy horde is on the horizon and the database team has banded together and barred the gates of Fort SQL Server to keep it at bay or die trying.

Unfortunately, the enemy is “change” and the DBAs have about as much chance of winning as cocker spaniel does in a fight against a pack of velociraptors. It really is just a matter of time.

The particular change du jour that some are stalwartly resisting is the encroachment of virtualization into the hallowed halls of SQL Server. This puzzles me because virtualization is a potentially beneficial change. However, conversations along those lines usually result in a “Keep that virtualization away from my SQL Server!” cry from these DBAs.

In computer history terms, virtualization is by no means a “new” technology. It’s been around for more than a decade. It has already been accepted as the foundation of the modern datacenter and the secret sauce for both public and private clouds. It is also the queen of the fully automated test environment.

Logic, logic, wherefore art thou logic? Can virtualization really be good for everything else, but not good for SQL Server?

Our customers that embrace virtualization and allow us to help them tend to find that it:

Adds almost no overhead (1-2% in most cases)
Provides some nice options for building (and rebuilding in DR scenarios) standardized servers from templates
Gives the only type of failover (either vMotion of Live Migration depending on your invading virtualization horde of choice) that keeps SQL Server’s hard earned self-tuning knowledge
Increases the available options for server consolidation which usually improves both hardware utilization and HA/DR options

That is not to say that the pathway to virtualization is a cakewalk which doesn’t have its challenges. Typically, there is new knowledge to be gained and new skills to master. Service monitoring becomes a must have to thwart the “noisy neighbor” scenario and other resource conflicts. At many companies, the DBAs become more reliant on the IT operations staff for certain tasks they previously owned – up to and including some types of failover. However, none of these is by any means terrifying to IT professionals. This is partially because no other field progresses as fast as computing, and over time we’ve gotten used to the pace of our changing technologies.

My business partner Allan has also seen quite a few of these SQL-under-siege situations. It is one of the main reasons that we are teaming up for a talk about virtualizing SQL coming up on Wednesday July 8 at noon EDT for the PASS Virtualization virtual chapter (http://virtualization.sqlpass.org/). If you are interested, please join us there. Click here to register.

Our goal is to help you understand what long-term benefits Hyper-V brings to the table so you will be leading the team doing the planning and deployment. In the end, a great Hyper-V implementation the best defense of all.
