If you’re coming from a perspective of managing on-premises infrastructure, you might understand the notion of “disk provisioning”. In VMware land this usually offers you a chocolate box of “Thin Provisioning”, “Thick Lazy Zero” and “Thick Eager Zero”.
Making a decision on the disk provisioning type has a consequence on the management of the VMware datastores. This is another topic entirely.
In Azure, my interpretation is that all VMs disks are “Thin Provisioned” and there’s no control exposed to the Azure Administrator to change that, which is fine. I’m happy to have that decision taken away from me.
The point I’m getting at here is that when you choose the size of data disks to attach to your VM, you’ll only be paying for the space you’ve used or written to in that disk. There are other things to consider when you’re not using Azure Managed Disks like maximum sizes that can be protected with Azure Recovery Services Vaults or other service limits, but once you’ve considered those limits and worked out your sweet spot, you may aswell choose the largest size of disk that works for you (a consistent large size of course!) to avoid inflating disks later down the road.

Part 1 of 5 linking to the most appropriate documentation for learning how to achieve the objectives set in the new Azure AZ-100 exam. More specific configuration examples will be added in PowerShell as I work through the subject matter myself.
A friend on Reddit added the latest content from Ignite. Could be a good place to start before begging with my posts.
Also, please consider this guide from Skylines Academy for your PowerShell skills to bolster your competency on Azure and for the AZ-10x exams.
Global Administrator is required to assign roles and is the default “god-like” administrator role in Azure. In Microsoft Graph API, Azure AD Graph API, and Azure AD PowerShell, this role is identified as “Company Administrator”. It is “Global Administrator” in the Azure portal.
A little misleading in the title. Policies can be assigned to resource groups within subscriptions. So, you can’t assign a resourece group to a subscription and walk away. Assigning policies to resource groups is useful for ensuring things like selecting which VM sizes are available or which locations are available for services to match organisational policy.
Microsoft’s recently announced an update to the Azure exam track, replacing the administration, developer and architect exams. The administration exam “Implementing Microsoft Azure Infrastructure Solutions 70-533” is being replaced with the “Microsoft Azure Infrastructure and Deployment AZ-100” and “Microsoft Azure Integration and Security AZ-101”. Both are available in Beta and I’ve committed to take the AZ-100 early August.
If you have already passed the 70-533, you can take a transition exam, the “Microsoft Azure Administrator Certification Transition AZ-102”.
The 70-533 exam held the following measurement categories;
Design and Implement Azure App Service Apps (10-15%)
Create and Manage Azure Resource Manager Virtual Machines (20-25%)
Design and Implement a Storage Strategy (10-15%)
Implement Virtual Networks (15-20%)
Design and Deploy ARM Templates (10-15%)
Manage Azure Security and Recovery Services (25-30%)
Manage Azure Operations (5-10%)
Manage Azure Identities (5-10%)
The AZ-100 exam holds the following measurement categories;
Manage Azure subscriptions and resources (15-20%)
Implement and manage storage (20-25%)
Deploy and manage virtual machines (VMs) (20-25%)
Configure and manage virtual networks (20-25%)
Manage identities (15-20%)
I’m happy to see “Design and Implement Azure App Service Apps” drop off. It wasn’t appropriate from the perspective of a on-premises compute administrator moving to administer Azure. The subject was so abstract that I had to read Sasha Rosenbaum’s great book “Serverless computing in Azure with .NET” just to even try to grasp what was going on in the 70-533 training material. Learn a thing just to understand why I’d do a thing.
How the “Design and Deploy ARM Templates” is either de-focused or folded into the Deploy and Manage Virtual Machines section will be for me to see on the exam, but I’ll assume it’s implicit in “Deploy and manage virtual machines”.
Overall, I’m looking forward to this unexpected challenge. I’ll report back on the 9th to give a steer on the learning content that’s most applicable for the exam.
I write this because there’s a notable difference in meeting people to discuss ideas, solve problems and agree on outcomes when people either have or haven’t had coffee.
I often warn people upfront “I’ve had coffee, so if I start whatever, let me know”.
What follows are a mix of subjective and objective observations with coffee providing a route to use for the worlds most popular drug, Caffeine.
Positives of coffee
Helps achieve a level of mental alertness “on-demand”.
Good black coffee has been considered to be a positive fuel for your microbiome.
The ritual around getting or making coffee has social value.
A good coffee tastes damn good
Negatives of coffee
Coffee makes my mind a little tight. The best description is that it doesn’t allow for space in my mind, I become wired to a thing or a thought train. This can be useful in a result oriented sense when needing to get from A to B with some technical operations, but outside that focused use case, I consider it a negative.
If I were coffee shopping and I could choose “no Jitters”, I would. Some coffees make me feel completely on edge, jittery, heart palpatations, all sorts.
A bad coffee tastes the worst.
A badly judged late coffee hit will mess with your sleep. This is NOT okay. Sleep is crucial to a happy life for me and staring at the ceiling is not something I’m a fan of. I have in the past subjected myself to intense anxiety over loss and the result of that is not something I’d recommend for anyone.
This is just a light heaerted post and not meant to be an exhuastive list of all the good and bad effects of Coffee and Caffeine, but I do find the social effects the most troublesome which created the motivation to write this.
I imagine most of the world is more social in their working and daily lives than me. My professional life demands large quantities of “me time”. When I come out from that zone, a poorly timed coffee for either me or my co-workers often makes life more difficult than it need be.
Microsoft offer Office 365 E1 as a donation to non-profit organisations and is well known. Exchange Online is a popular feature of Office 365. Running your own e-mail system in 2018 is a chore. The service limits are way and above what most people need.
What is less well known is that there’s an opportunity to benefit from $5000 USD of Azure credits per year for non-profits, too.
This can be enjoyed by following this URL and applying for the credit;
It’s a little like in the old days, you called a test Human Resources application server
hr-test.company.internal for example, both as it’s hostname and it’s hypervisor name.
Then some combination of events end up with the system going live and you’re looking at a box with “test” burnt into the name. It makes you sad, it confuses contract staff and is an all round fail.
What I’m getting at is that you’re likely to test some services and perhaps even make them live. But at some point you will probably start running out of that $5000 USD and have to move the resources onto a different subscription to allow them to contine functioning. Beware of creating services that aren’t able to be moved to a subscription that you can’t maintain or re-hydrate with funds.
I’m feeding back to our Microsoft account manager this week to suggest a different model for the donation. One where MS ask for an existing subscription like a credit card Pay-As-You-Go subscription or an EA subscription. Then, at least, there’s a parallel billing mechanism that you can support the resources allocated to that subscription.
