    Azure World Newsletter – Issue 4.17

    August 23, 2023

    Welcome to the seventeenth edition of the Azure World Newsletter in 2023.

    Hello again, my friends from around the world. I’m so happy you continue to subscribe and read this bi-weekly newsletter on Azure. I enjoy sitting down each week to research and write this, and hopefully, you will continue to find value in it. Feel free to invite your co-workers or others to subscribe if you think they would find it helpful.

    Not much has changed in the world of Azure in the last two weeks. So I considered skipping this one and returning in September, but then some big exam news broke.

    ONE.

    The big news this week is that Microsoft is making a small but important change to its exam policy.

    Starting soon, you will be able to browse the Microsoft Learn website while taking any of the role-based certification exams.

    This means that if you encounter a difficult question, you can click a button on the exam interface to view the Microsoft Learn website content, which includes Microsoft Documentation. You can browse the topic you are interested in and look up the details you need to know. Then return to the question, hopefully with the answer you need.

    Some are calling this a move to “open-book exams.”

    There’s an important thing to realize with this move. You’re not getting any extra time for the test, so you can’t exactly spend all the time you need looking up any question. But for those questions where you “kind of” know the answer and just need to quickly look it up to verify, this could be a lifesaver.

    This is a bold move by Microsoft. You might think that this makes the tests easier, and perhaps it does. But in the real world, if we don’t know something, we can quickly look it up. So having to memorize the amount of RAM a memory-optimized virtual machine instance had in the real world is unrealistic.

    Apparently, they are not changing the questions because of this move. Partly, that is because the questions on Associate and Expert exams are generally not trivial. Also, it may not be possible to do deep research on every question to pass the exam, so you will probably want to use this resource sparingly.

    Azure World Newsletter – Issue 4.16

    August 9, 2023

    Welcome to the sixteenth edition of the Azure World Newsletter in 2023.

    Some think summertime is a good time to take it easy. Many sensible people go on vacation this month, and even some businesses shut down around this time for a holiday break. Not Microsoft, however. In the past month, Microsoft has decided to update almost every one of their exams. So I have been busy recording videos to update my courses to cover the new topics.

    Luckily, they often remove topics from exams, too, so that’s somewhat easier to deal with. Either way, I have that familiar feeling of trying to catch up to the changes that seem to happen simultaneously. Luckily, things should be quiet for me from now until MS Build happens in November. If past history repeats itself.

    Azure seems to be testing a new way to manage large numbers of resources in a simplified fashion. This method is called Deployment Stacks. This new resource is in Preview mode.

    A Deployment Stack is a set of resources deployed using a single ARM Template or Bicep. A deployment stack can be created at different scopes – resource group, subscription, and management group scope.

    A stack can deploy resources across multiple resource groups or subscriptions. You could, for instance, deploy a developer jump box with a public IP and RDP enabled across several regions at once.

    You can then make bulk updates to all resources in the stack, such as deleting all of the resources using a single call. You can also use stacks to block unwanted changes to the group of resources it controls.

    If this sounds interesting, you can read more about it here.

    TWO.

    As much as I don’t like the name of Microsoft Entra ID, I do like the name of a new Azure feature called Azure Boost.

    Boost sounds fast. And it is.

    Actually, maybe they should have called it “Turbo Mode.”

    Unfortunately, Boost runs behind the scenes at the data center hardware layer, and I probably will never get to interact with it directly.

    Azure Boost offloads the virtualization process that the hypervisor (and host OS) usually performs onto custom-developed hardware and software.

    By taking the virtualization function away from the host, Azure Boost significantly “boosts” the networking and storage throughputs that customers can expect to see.

    For instance, with Azure Boost, a VM can see 200 Gbps networking throughput and a storage throughput of up to 400,000 IOPS at 10 Gbps.

    For now, you can’t specifically choose a VM host with Boost enabled, but Azure has been working with certain customers to test it. In fact, Microsoft claims “millions of Azure VMs” are getting the benefit of Boost without even knowing.

    COMING UP FOR ME.

    Been hard at work with a few things. Microsoft dropped dozens of changes across multiple exams during July, and I had to obviously go and make new videos for those courses. AZ-900, AZ-104, and others received updated content. My teaching assistant Sean Xie quickly updated the study guide for AZ-900 for the new requirements. So there’s lots going on.

    And still, I was able to complete a new TOGAF 10 Part 1 certification course that is being published on Udemy. TOGAF 10 is just a relatively small update for the foundational level content, but all new videos have been recorded, and the course is available for students to join.

    Every three months, we get a peek inside Redmond’s books with their quarterly earnings announcement. This quarter, they were able to beat analyst expectations by earning more revenue and higher earnings than expected. Microsoft’s overall annual growth rose only 8% year-over-year.

    Somewhat more relevant was how their “Intelligent Cloud” segment did. That segment was up 15% year-over-year and includes Azure, SQL Server, Windows Server, Visual Studio, GitHub, and other enterprise services.

    Azure revenue reportedly grew 26% annually. They do not report this revenue in dollars, so it’s hard to compare the overall total with competitors in the space, such as Amazon Web Services.

    I can remember, not too long ago, when Azure was growing at more than 50% year-over-year, and so clearly, the growth is starting to slow. They are still growing faster than AWS, so over time, Azure will close the gap, although it might take a long time.

    This earnings report happens in the middle of some cutbacks at Microsoft. Recently, Satya Nadella mentioned there will be more job cuts coming up. And Microsoft has also frozen salaries.

    Last year, I noticed documentation on the Microsoft Learn website mentioning that Azure Active Directory (Azure AD) would be part of the new Microsoft Entra umbrella of services.

    Well, the other shoe has dropped on that. Azure AD itself is being renamed Microsoft Entra ID.

    Before criticizing the new name, I must stop and wonder why they had to change it. Did the Azure AD name make it confusing as to what the service could do? Were customers failing to adopt it because they were confused by the name? Was the old name limiting the service in some way?

    Given that Windows Server Active Directory has a long history before the cloud was a dream, clearly, the Azure AD moniker was not that confusing. It was a continuation of what Windows AD was but in a cloud context. It was not a total feature-for-feature replacement, but there was a lot of overlap.

    Were customers not adopting Azure AD because of the name? I don’t believe they were. Millions of enterprises around the world were using Azure AD.

    But was the old name limiting the future potential of the service?

    Maybe. This might be the reason they decided to change the name. Maybe Microsoft wants to grow the Azure AD brand beyond its “AD” roots.

    So Microsoft Entra ID is re-branding itself as a “multi-cloud” identity security service. It does not require the use of AD internally, it does not require Windows, it does not even require Azure.

    Entra ID is identity as a service that can be used quickly and easily in a variety of modern multi-cloud, heterogeneous environments.

    Microsoft is quick to point out that only the name is changing. You don’t have to do anything to your apps or code. It’s just a rebranding.

    I understand the need to change the old name. I don’t like the new one, but if they wanted to repaint their 30-year-old AD as a brand-new thing, I get that. But Entra is going to take some getting used to.

    Surely there were better names. “Microsoft Identity Services” even.

    Data encryption over the wire (in transit) is always an interesting topic, and I saw an announcement from Microsoft about something that caught my eye.

    Microsoft is testing the encryption of traffic on a virtual network level. It’s called Azure Virtual Network encryption and is in preview mode.

    Currently, a lot of traffic is already encrypted between various Azure services. For storage accounts, HTTPS-only traffic is the default setting. When data is traveling between Azure data centers over the Microsoft internal network, that traffic is also encrypted. When you set up a VM, you obviously have control over whether it communicates with the outside world using an encrypted channel (HTTPS, SSH, SFTP, etc). So a lot of this exists already.

    But there is a feature in preview mode that currently encrypts traffic traveling between virtual machines on a virtual network over a private IP address.

    This feature is limited to a very short list of VM instance sizes over Accelerated Networking interfaces. It’s also only available in a few regions currently.

    If traffic encryption is important to you, even between two virtual machines on the same virtual network, then you may want to investigate this. Of course, it would take a really sophisticated hacker to have access to Microsoft’s internal networks to sniff the traffic if it was unencrypted, but the world is full of sophisticated hackers, unfortunately.

    TWO.

    One of the new services announced at Microsoft Build was the Dev Box.

    The Microsoft Dev Box service is a set of ready-to-go, cloud-based workstations for developers. Instead of having to configure your local laptop or desktop with all the tools you need to do development, you can just connect to a remote computer with everything ready to go. This means that you can go anywhere from the office, to home, to a cafe, to a client’s office – and have your full development environment already set up and ready to use.

    This also allows you to have different dev spaces for different projects. One Dev Box can be data engineering focused, with tools for working with machine learning models, large amounts of data, and powerful GPU and memory configuration that data engineering usually needs. While another Dev Box can be focused on front-end web development, with all the tools you like to use to create that code.

    Dev Box is now generally available.

    I’m excited to share with you all that I am currently developing a new course on TOGAF version 10, designed to equip you with the most relevant and updated enterprise architecture principles. My goal is to have this course launched by the end of July, offering you a comprehensive understanding of this robust framework. As I work towards preparing this material, I’ll also be taking a short vacation to recharge. In the interim, I hope each of you gets the chance to relax, embrace the sunshine, and enjoy your summer safely. Looking forward to rejoining you all soon with this empowering new knowledge tool.

    In the last newsletter, I briefly listed a bunch of CosmosDB features that were announced at Microsoft Build. They were:

    • Azure Cosmos DB burst capacity, in GA
    • Azure Cosmos DB serverless container with 1 TB storage, in GA
    • Azure Cosmos DB hierarchical partition keys, in GA

    All of these new features are now generally available, which means you can access them for production workloads starting now.

    Burst capacity allows you to “bank” some of the idle capacity of your Cosmos DB database and then be able to use that extra capacity if there is a spike in requests later. It’s like a battery! You can accumulate up to 5 minutes of idle capacity at a time, and then Cosmos DB will use that saved capacity the next time there is a spike in traffic that would normally exceed your RU/s limits.

    Cosmos DB uses partition keys to split a database across physical partitions if required. For instance, if the partition key on your database table was “Car Make,” then all of the cars of the same make will be stored in the same physical partition on the disk, while it’s possible that cars of other makes will need to be stored separately depending on how big the database gets.

    There is a limit of 20 GB for a single partition. So if you think that you will need more than 20 GB of data for a single partition key, you will need to choose another key.

    This can be less than ideal. Choosing another partition key could result in undesirable things, such as forcing all queries to be cross-partition, thereby driving up the cost.

    Cosmos DB now supports hierarchical partition keys. This allows you to choose up to three partition keys which will be used in hierarchical order when splitting up the data.

    In our example, we could make the partition key first “Car Make,” and then “Car Model”, and then “Car Year”. This way, if partitioning the table using “Car Make” doesn’t result in it being over 20GB, the partition does not need to be split. But when the size reaches the limit, the table will be partitioned according to “Car Model”.

    It’s a clever solution to a problem that probably only affects a small number of customers but a welcome solution to them.

    Serverless Cosmos DB has been available for a while, but has had a database limit of 50 GB until now. During Microsoft Build, Microsoft announced the storage limit was being increased to 1 TB.

    If you rely on Cosmos DB for some of your data, you should check out the announcements from Microsoft Build.

    One of the ways the big three cloud providers (AWS, Azure and GCP) compete for business is by trying to get regulators to take action against their competitors.

    When Microsoft Azure was granted the big JEDI contract from the US Department of Defense, Amazon was in court trying to get the award stopped. And eventually, they even won. The latest was that Amazon had won a larger share of the JEDI contract with Microsoft also getting a piece.

    In the latest spat, Google is now trying to get the US Federal Trade Commission (FTC) to investigate Microsoft Azure for anti-competitive behavior.

    The FTC is actively asking for public feedback on competition in the cloud computing space, and of course Google wants the government to break up the Amazon-Microsoft public cloud duopoly if they can.

    Google is arguing that Microsoft is leveraging its monopoly in Windows Server and Microsoft Office in the cloud. Google claims that its very difficult to gain a foothold with companies for its own Google Cloud Platform since companies have very complex licensing arrangements with Microsoft.

    Google even invoked the SolarWinds security breach in its filing. Having Azure as a dominant player in the cloud is apparently a national security threat.

    You can read the public responses from Google, Amazon, Microsoft, Red Hat, Oracle, and the EFF on the FTC’s website.

    Late last week, I saw a post on the Azure User Group Facebook group about being unable to access the Azure Portal. Accessing the “Preview Portal” seemed to be the easy way around that at the time. This outage apparently also affected Entra Administration and Intune.

    CLI and PowerShell continued to work, Microsoft has said.

    This week, the preliminary root cause of the outage is being blamed on a “traffic spike.” Coincidentally, a known hacking group has claimed responsibility for a Denial of Service attack. Microsoft hasn’t confirmed if the claims are accurate.

    This is a reminder that you should have alternate ways to manage your Azure resources ready to go before becoming completely reliant on a single method. If accessing your resources is essential to your work, having the command line tools (and modules) already installed and tested will save you time when another method suffers even a short outage.

    All cloud providers are going to have these issues from time to time, especially if it’s caused by a malicious actor. But you can follow some of the steps in the Root Cause Report below to prepare yourself for these things that happen occasionally.

    See the root cause report here:
    https://azure.status.microsoft/status/history/

    And an interesting blog here:

    Amazon AWS has had its own distro of Linux for almost as long as I can remember. So when you deploy an EC2 instance in AWS, you are offered Amazon Linux as the default and have to specifically choose a different distro if that’s what you need.

    After a couple of years of testing, first privately and then publicly, Azure now has its own version of Linux too. Azure Linux is now in general availability.

    This makes sense from a couple of viewpoints.

    One, Microsoft needs a standard version of Linux for its own projects. Instead of every team choosing a different distribution vendor, or the company standardizing on one of the vendors, they created their own Common Base Linux (CBL) that can then be the standard for all their internal projects.

    Azure Linux is also specifically designed for the Azure cloud and to run container workloads. They can ensure that this version of Linux runs on their own platform better than any other vendor.

    Azure Linux is mainly used for containers. If you’re going to run your own workloads in a Linux VM, you probably have a specific version that you are developing against and reasons to choose one distro over another. But for containers, the container itself is the platform you are developing for. You’re generally not going to care which distro its deployed to.

    You can read about Azure Linux for Containers in this blog post:

    An interesting new feature of Azure Storage was just announced: Cold Storage.

    As you know, there are currently three access tiers for Azure Storage if you don’t count the Premium tier: Hot, Cool, and Archive. Azure announced a new fourth tier called Cold.

    The cold access tier fills the gap between Cool and Archive. Cold Storage is less than one-half of the price of the cool access tier. Cold Storage does not require “thawing,” unlike the Archive tier. So files are available for API calls immediately. But it has a 90-day early deletion policy, which means it is clearly intended for longer-term storage. Read operations are significantly more expensive than the cool access tier; 10 times more expensive, in fact.

    Cold Storage public preview is now available in Canada Central, Canada East, France Central, and Korea Central.

    TWO.

    Azure App Service is getting a new scaling option called Automatic Scaling.

    You know that App Service Plans already have autoscaling and manual scaling, so what is this new Automatic Scaling option?

    Well, that’s interesting! Automatic Scaling scales individual web apps, instead of scaling all apps on the same App Service Plan. And instead of setting your autoscaling options based on resource metrics like CPU utilization, Automatic Scaling is designed to scale based on incoming HTTP requests to a particular web app.

    Automatic Scaling does not have “rules” in the way that autoscale has. Azure will just scale your app up and down (within preset boundaries) as HTTP requests come in.

    Azure will add more instances to a particular web app based on incoming requests. It can pre-warm these instances so that there is a smooth scaling up when there is an increase in requests.

    This allows different apps on the same app service plan to scale according to need and not be forced to all scale together.

    Automatic Scaling is in preview mode.

    The annual Microsoft Build event happened last week. This event is aimed at developers and often has some interesting announcements. In this newsletter, I cover some of the most interesting things announced at Build.

    • Microsoft announced that it would adopt the same open plugin standard for its AI services as OpenAI did for ChatGPT. This is so that plugins developed for ChatGPT can also be used with Microsoft’s “CoPilot” offerings (and vice-versa). This is an interesting move. Standards are better than making your own proprietary format, obviously. As well, the copilot services now come with hundreds of pre-developed plugins that should work too. Making it immediately useful.
    • Microsoft Fabric is a new preview service that integrates all analytics workloads, including Power BI, Data Factory, and the next generation of Synapse, in one unified SaaS model. Fabric will also have a copilot integrated, so that you can us AI to help you generate code, enable custom Q&A, and deploy to Microsoft Teams, Power BI and Web.
    • Cosmos DB now supports hierarchical partition keys. This allows you to have up to three partition keys on your data, without giving up the performance you usually have to when having multiple partition keys. This is generally available.
    • Cosmos DB now supports Materialized Views. Views are a concept from the SQL Database world that allows you to create and maintain secondary views of data that are more costly. You can now query the views instead of the data directly, which should improve query performance.
    • The open-source project Prometheus now has a fully-managed service in Azure. Prometheus is a common standard for monitoring containerized workloads. It integrates with Azure Monitor.
    • Azure Cost Management is getting a new AI buddy. You can ask it why your bill is so high, how can you reduce costs, or to get quick insights and recommendations on your usage of Azure resources.
    • Finally, a new Azure Deployment Environments service, now in general availability, allow developers to use the service to self-deploy the environments they new on demand using infrastructure-as-code templates like ARM and Terraform. So if you need to spin up a new dev box for some reason, you can do that from the Deployment Environments dashboard instead of having to find the specific template you want yourself.

    You can find more about these announcements by watching the Microsoft Build reruns, or by looking at the Book of News below for more direct links to articles and documentation on that.

    Azure Storage Mover is exactly what it sounds like – a migration service that helps you move your files and folders to Azure Storage.

    There are a few existing solutions for moving files to Azure Storage. They include the upload feature in the Azure Portal, azcopy command line tool, Azure File Sync, and Storage Explorer. And now, we have Azure Storage Mover as a specific tool for this exact purpose.

    One of the challenges of mapping a traditional “folder structure” to Azure Blob Storage is that it’s non-hierarchical. So how do you represent folders that contain other folders and may (or may not) contain files in a Container model?

    Storage Mover will prepend the file’s path to the blob name so that its position in the hierarchy is preserved. And empty folders will be represented by empty blobs. The metadata of files and folders is preserved in the blob’s metadata.

    Storage Mover is a hybrid cloud service in that it’s a cloud service with an on-premises element. So, of course, you need to install an agent app in your environment to synchronize files. And that can be scheduled and repeated occasionally.

    https://learn.microsoft.com/en-us/azure/storage-mover/service-overview

    Running apps inside of containers provides a lot of benefits for the deployment of applications, but does come with some restrictions. Oftentimes, the app is sandboxed in AKS and is dependent on outside resources that it can’t control.

    For example, you can’t deploy an app into AKS until the Azure resources it depends on have previously been deployed.

    This problem can be solved using the Azure Service Operator (ASO) project. ASO is an open-source project that you can find on GitHub. This allows the deployment process of an AKS container to also deploy Azure resources as well.

    Now, of course, any app can interact with the Azure Resource Manager by REST API with the correct credentials, and interact with the underlying Azure resources in this manner. Or you could install the bash CLI into the container and use that to issue commands to Azure. That’s not an elegant solution.

    ASO simplifies this by adding a couple of conveniences. First, it lets you interact with Azure resources using familiar Kubernetes tooling and primitives, like issuing kubectl commands.

    For instance, you can define resources like resource groups, CosmosDB databases, SQL databases, and more inside a YAML file, and use kubectl apply to get those resources provisioned.

    Microsoft recently announced that version 2.0 of the project has reached a stable milestone.

    ONE.

    One of the interesting announcements that came out in the past two weeks is around new tiers for Azure App Service Premium V3.

    For instance, there is an App Service P0v3 tier. P0 is obviously smaller than the existing P1 tier and offers 1 vCPU and 4GB of memory.

    The P0v3 app service plan (for Linux) can cost around $73/month on a pay-as-you-go pricing, and the price falls to as low as $33 per month if you have Azure Reservations.

    The Premium V3 tier of app services includes increased disk space (250 GB) and can be scaled up to 30 instances compared with the standard tier.

    There are also new “memory-optimized” versions of the Premium V3 app service plans, called P*mv3, labeled as P1mv3, P2mv3, P3mv3, and so on. This allows you to have additional memory for your apps without having to scale to more cores, similar to the way memory-optimized VMs work.

    For example, the regular P1v3 service plan comes with 8GB of RAM, while the new P1mv3 plan comes with 16GB. So you can see how this can be used to save you money. You can continue to use P1 plans without having to upgrade to P2. The P1mv3 plan only costs around $20 per month more than the regular P1v3 plan.

    TWO.

    There’s a bit of a trend in Microsoft Azure to offer two different pricing options for many popular services. You can either pay a fixed-price per month for dedicated computing services, or opt to pay for consumption in a serverless option.

    The concept of serverless in cloud computing is simply the ability to pay “per execution” or “per query” for a cloud service, instead of paying by the hour. You lose control over the underlying hardware (CPU speed, RAM, etc) and gain a promise from Azure of a certain level of performance.

    Many services offer serverless options alongside the “fixed-price plan” option. Functions can be serverless or in an app service plan. AKS has a serverless option. As well as Azure SQL Database, and Cosmos DB. Azure Container Apps now joins the list of having both options.

    Azure Container Apps was serverless when it launched, and now you have the option for a dedicated pricing plan. Under the dedicated pricing plan, you can make some basic selections up front for the type and size of the workload you intend to run. You can deploy as many apps as you want to that dedicated compute platform, scale it as required, and place limits on the scaling to control costs.
