I haven’t made a decision on putting databases in the cloud. I think Amazon and now Microsoft have the write idea for cloud databases. Give people lots of options, use named value pars (AmazonDB or the old school Azure database) when it makes sence and use full blown RDBMS when it makes sence.
But the big question that I have (besides pricing) is how does all this fit into the overall picture for my company or my client.
Do I see a lot of large enterprises moving large parts of there environment into the Cloud? Probably not.
Do I see the small/medium business moving customer facing applications to the Cloud? Possibly, it’s going to depend on the application and the business model.
Do I see the cloud being a stepping stone in a eventual path to building your own data center? Very much so.
Why don’t I see large enterprises moving data into the cloud? Mainly control and compliance. Large companies (and even larger medium sized companies) want to control everything about there data. They also need to be able to ensure that no one who isn’t authorized to view the data can’t view the data. The easiest way to do this is to own the machines that have the data. Large companies also have to have DR plans. Those plans usually can’t depend on some other company doing “Yes, it will be back up.”.
I said above that I see the cloud being a stepping stone to getting your own servers and data center. The path that I see in my mind is for the small to medium business who can’t afford to setup their own servers onsite or at a colo. For them cloud computing is a great first step to let them get started and see where the application goes. If nothing happens, then there isn’t much capitol lost. If it grows like crazy then everything scales nicely (not yet sure how well and automatically the databases scale). This gives the SMB the ability to judge where the business is going to go and how fast it’s going to get there.
Some applications may be able to stay in the cloud forever. Either they persist a lot of the data at the client, or they simply never outgrow the cloud. On the otherhand I see a lot of applications going from running in the cloud to moving to an MSP (Managed Services Provider) such as Rackspace, MaximumASP, etc. These guys offer the benifits of dedicated hardware, without having to shell out the massive amounts of cash up front. Over time however it becomes cost ineffective to continue at an MSP, and buying your own hardware simply becomes the correct thing to do. The trick is knowing when this is the case, so that you aren’t spending a lot of money at the MSP.
Now for those that were paying attention, you’ll noticed that I skipped the point above about the SMB moving somethings into the cloud. I think this falls into both answers above. Some things will make sense to host up in the cloud, other things won’t.
What do you think will happen to the cloud? Where do you see it being really useful? Will you be moving applications into the cloud at your current company, at a future company?
These are questions that you’ll need to ask yourself at some point, so why not now? In these times of rapid change to the IT world (and the world in general) don’t be afraid to change your answers to these questions.
Personally I don’t get most of the social networking sites / products / whatever you want to call them. Continued »
If your company does business in the state of California then don’t forget to change the sales tax rate in your shopping carts tomorrow.
That’s right, tomorrow the state of California will be playing the worlds worst April Fools Day prank. We will be increasing our state sales tax by 1% tomorrow April 1, 2009. Depending on the county you live in sales tax could now be as high as 10% as some counties are also increasing the county sales tax as well.
At this point I’m betting my boss is pretty happy that we finished the purchase of our new SAN and servers in March (a blog post about the project will be later). The increased rate of a $700k (US) purchase would be another $7000 (US) to the state goverment.
If you don’t collect enough sales tax, you still have to pay the correct amount to the state, so that extra money that you don’t collect could eat into the bottom line pretty quickly.
If you don’t already read the CSS teams blog, I suggest that you do. A little while ago they posted a blog post about how the SQL Dumper utility wouldn’t work in a SQL Server 2008 Clustered Installation.
This should be considdered mandatory reading for anyone with a SQL Server 2008 install in a cluster.
I just published another article up on SearchSQLServer.com. This one is entitled Testing a SQL Server environment before an upgrade. In it I talk about some successes and some failures that I’ve seen when upgrading SQL Server versions and how the failures could have been avoided.
Hopefully you have seen one of the “Did you know” videos that are on the web. If you haven’t I highly recommend that you do. I’ve included the four versions which I’ve found below.
I’ve found these videos quite interesting to watch, especially as you watch the different versions and see the numbers being updated and changing over time. After you watch theses I invite you to talk with people about the message that you got from these videos. I look forward to your comments either here, on Twitter, via email, or in person.
For those that don’t know the first of these videos was created by Karl Fisch for use at a beginning of the school year meeting. You can read up more about Karl on his site and more about Shift Happens.
The original (which I uploaded to YouTube to make it easier to view). In this video he refers to AHS which is the school he teaches at, or at least he did at that time.

Last week Linchi Shea wrote a posted a blog entry entitled “How does that AD user account get access to the database?“. In it Linchi shows a method of finding out the domain groups that a SQL Server user uses to access the database.
There is however an easier, method you can use.
There is a system extended stored procedure called xp_logininfo. Microsoft was even kind enough to document the procedure for us. You can use this procedure to see what group a use belongs to, or what users are in a domain group, all from T/SQL.
For example, on my sandbox instance if I run
EXEC xp_logininfo 'CORP\dcherry'
I get a result set which says that I gained my access to the SQL Server via the “BUILTIN\Administrators” group.
This is a nice quick and easy method to see what domain group a user used to access the SQL Server.
I didn’t know this was such a well guarded secret. Which leads me to a story to share. I had a supervisor (Ed) back at EarthLink who made it a point to have story time during his pre-shift meetings, those were the best days to be working. I remember that Ed was on vacation once and our assistant supervisor Dennis was running the team. Well instead of telling us a story, he brought in a kids picture book to read to us. It was awesome, there were about 80-90 tech support reps all sitting in the break room hanging on every word from a book for 2 year olds. Funniest sight ever.
But that’s a whole different story than the one I wanted to share.
One one particularly long night at EarthLink, back in 2001 or so (I was using SQL 2000 at the time), I had a lot of database data changes to make (I have no idea why at this point). Probably business rules had changes so data needed to be changed, and indexes needed to be changed, or something. Needless to say SQL was going to be running queries all night long.
Well, having already worked 12-16 hours that day, I didn’t really want to stay up all night watching SQL run. So I cranked up the speakers on the PC as load as they would go (I had some nice speakers so they got loud), and set Windows to as load as it would go (I’m a heavy sleeper) and started the first of the T/SQL Scripts. I promptly curled up on the floor with my pillow and blanket that I had brought in and went to sleep. About three hours later I was woken up by the loudest “Windows ping” ever. It really scared the crap out of me, but it did the job. I checked what ever it was that needed checked and started the next script.
This happened probably three or four times through out the night. The next morning I took a shower (we had showers on site for just such nights), and changed my clothes (my wife was kind enough to bring me a change of clothes before she went to bed) and went on with my new work day, after technically pulling an all nighter that I slept through about 99% of.
If only all, all nighters were that easy.
This used to be a very easy question to answer as the answer was 1. However these days, with some creativity you can get some extra ones.
So, as you may have heard the SQL PASS 2009 Call for Speakers has gone out. I’ve submitted a couple of sessions already, but I was hoping to get some feedback from the community at large about what you think I should submit topics on.
I’ve submitted a couple of SQL Service Broker sessions, as well as a session on Storage, and a session on planning a database migration. I’ve got all sorts of stuff that I could submit, but if no one is interested in it, then there isn’t much point on trying to present those topics.
So I pose this question to you: If you were going to the PASS Summit this year in Seattle what would you like to see presentations on? Should I leave these sessions up there, or replace them with others?
