Azure Virtual Machine Blog Series – Changing the size of a VM

Posted on by

I’m starting a new blog series on Microsoft Azure Virtual Machines, and my goal is to write blog posts exclusively on Azure VM/SQL Server related topics.Here is the 1st post –

“Changing the size of a VM”

When creating an Azure VM to host your SQL Server, you have an option to select the pricing tier. This pricing tier states what will be your VM configuration in terms with CPU cores,memory,No of disks, IOPS etc.

Azure provides plenty of pricing tier options,and you have the power to create a VM with the least amount of configuration or pick a monster like below –

AzureVM1

Gone are those days where you had to think twice to move your SQL Server workload to the cloud because of the lack of compute power. 32 cores, 448 GB, 64 disks with 80,000 ! Can’t get better than this !

What if I created a VM with a standard pricing tier like DS1 Standard, and after running it for a while realize that it’s not meeting my needs, and my SQL instance starts freaking out.

AzureVM2

Hmm, bad planning isn’t? Yeah, it’s definitely bad planning, however Azure will cover you pretty well.

If I check the VM configuration, I can see its current configuration as 1 Core and 3.5 GB of memory. AzureVM3

If I go to the portal and choose the settings option for the VM and the select size, I have multiple selection options for pricing tier-

AzureVM4

If I scroll down on the selection options, I can see that the G series are not available. This means that you cannot scale up from a D series to a G series directly. Again, not planning ahead can give you trouble.

AzureVM5

 

What if I select DS3-Standard. Will it change my VM configuration on the fly?  Lets check it out –

On the portal I’m selecting the DS3 option which is 4 cores and 14 GB memory.

Note – This will restart your VM behind the scenes.If you are following this article and trying to change the pricing tier of a critical production server, then stop and plan to do this activity during a planned downtime.

AzureVM7

Within few seconds, I got an alert which says –

AzureVM6

 

Neat ! Lets check the configuration –

AzureVM8

Indeed the new configuration is applied after a quick reboot.

Conclusion – 

Flexibility to change the VM size pretty easy can come handy sometimes,however carefully analyzing the workload compute demands and choosing the correct sized VM is always the recommended approach.

Thanks for reading and keep watching this space for more Azure VM related posts.

Checking out Windows Server Technical Preview on Azure !

Posted on by

I’m a great fan of running the latest version of Windows Server whenever I deploy SQLServer. I always try to push the latest and greatest windows server builds along with latest SQLServer builds because of many reasons (That can be a whole different post altogether).

I was all excited when I heard that Microsoft released the Technical preview of Windows Server (They might eventually call it Windows Server 10,but not sure for now), and decided to set this up.

I just went to Azure and see if there is any template which is made available, and it was indeed available. Way to go Microsoft (Yep, I do praise good things !)

Win Server Tech

 

Gave it a name, sized it as I need and added few more details

Win Server Tech1

 

Win Server Tech2

Got little surprised to see all these new additions

Win Server Tech3

 

And there you go….Started provisioning my VM

Win Server Tech4

Once it was created. I downloaded the RDP file and got connected to it. When connecting to the server you need to make sure to use the ID and Password which was used while creating the VM.

As soon as I logged in I realized that there are no major UI changes, but what Microsoft did here is re-touch everything and made sure that a proper Start Menu is back.

Win Server tech1

 

You have an option to choose Start Menu or Start Screen(I’m not a fan of Start screen ! ) and that flexibility is nice.

Win Server tech4

Windows Server Failover Clustering is one of the most important feature which I deal with Windows Server as its one of the pre-requisites for AlwaysOn Availability groups, so I decided to just add that feature(Not going to configure clustering now).

Nothing new here. Its all old story with same UI.

Win Server tech12PNG

Win Server tech3PNG

Once it was installed, I went to Start menu to launch it. This is kind of neat and I like this way rather than using charm bar and searching for it.

Win Server tech5

Win Server tech6

You can also search failover cluster manager using the search option available in the start menu. There are the small things which I care about and like. Nice !

Win Server tech7

And well if you like Tiles, then you definitively have an option to pin it. I like to pin things like Cluster Manager etc.

So here you go

Win Server tech8

You also have an option to add multiple desktops. That’s kind of neat as I tend to open multiple windows and I can switch between desktop.

Win Server tech9

Conclusion :

That’s it for the UI changes for now. Nothing dramatically new and fancy,but I liked the way things look now. In the next few days I will configure clustering and will come with more updates.

Thanks for reading, and keep watching this space for more !

Building a Virtual Machine within Azure (IaSS) – Improvements !

Posted on by

Those Dev’s/UX designers out there at Microsoft seems to be pretty busy as they releasing back to back updates to windows azure portal over the last couple of months.

I had to create a VM in Azure to do some testing, and this time I decided to try out the new portal. Apparently, I’m not a great fan of Windows 8 styled tiles, but on Azure portal these tile like options are not that bad.

I selected virtual machine from the add button(+) and the portal gave a nice view of the available options  :

Create VM

I’m pretty impressed with the amount of flavors you have now for the VMs. Oracle Linux, Open SUSE ! Cool !

I picked SQL2014 standard, and started the create process. When you start entering the details like host name, user name etc. everything looks same as before but as you click the pricing tier, there comes some improvements.

You now have an option to check all the pricing tiers and can get an idea on the approx. monthly costs pretty easily.

Click the image for better resolution.

Create VM2
Icing on the cake is the Max IOPS numbers. This is way cool and handy to know and have.

Create VM3

I chose something small and started exploring more. I gave the hostname and all other required things and chose check box, “Add to Startboard”. This will just add the new VM to azure portal home page.

Portal started giving me cool visualization when the VM was getting created, and the current actions were getting displayed in the notifications area.

Create VM4

As soon as the VM was created its details were made available in the startboard. There are some cool data like Disk, CPU, Network etc. which definitely will come handy for everyone.

Create VM5

The process to add an alert for a specific matric looks pretty straight forward within the portal. I tried to set an alert for disk, and here is what the portal has to offer.

Create VM6

Overall, I’m really glad the way Microsoft Azure has improved over the last couple of years and now this is shaping up to be one of the trusted platforms to host critical workloads with great management capabilities.
