In the Data management section, select the Lifecycle management blade. Select Add rule.

Set the Rule name to movetocool. Set the Rule scope to Apply rule to all blobs in the storage account. Select Next.

Ensure Last modified is selected. Set More than (days ago) to 30. In the Then drop-down select Move to cool storage. As you have time, review other lifecycle options in the drop-down. Add the rule.

Step 2
The public website files need to be backed up to another storage account.

In your storage account, create a new container called backup. Use the default values. Refer back to Lab 02a if you need detailed instructions.

Navigate to your publicwebsite (you could create a new one or any previous storage created before) storage account. In the Data management section, select the Object replication blade. Select Create replication rules.

Set the Destination storage account to the private storage account. Set the Source container to public and the Destination container to backup. Create the replication rule. Optionally, as you have time, upload a file to the public container. Return to the private storage account and refresh the backup container. Within a few minutes your public website file will appear in the backup folder.

Conclusion

Establishing private storage for internal company documents on Azure is more than a technical exercise—it is a strategic investment in organizational security and resilience. By carefully configuring storage accounts, enforcing encryption, applying role-based access controls, and leveraging private endpoints, businesses can create a secure environment that protects sensitive information from unauthorized access. Beyond compliance, this approach fosters trust among employees and stakeholders, ensuring that critical data remains both accessible and safeguarded.

A Step‑by‑Step Guide to Creating a Windows Server 2025 Virtual Machine in Azure

adegbola adeniyi — Sat, 21 Feb 2026 12:19:44 +0000

Introduction

If you’ve ever felt like the Azure Portal looks more like a cockpit than a website, you’re not alone. We’ve all been there—staring at a dozen menus and wondering which button actually does what. But here’s the good news: deploying your first Windows Server 2025 VM is much easier than it looks.

> "Windows Server 2025 isn't just an incremental update; it’s a bridge between traditional on-premises reliability and the hyper-scalability of the modern cloud".

Windows Server 2025 is the newest powerhouse in Microsoft's lineup, featuring faster storage, tighter security, and a much smoother hybrid-cloud experience. While it represents the "cutting edge," you don't need to be a veteran systems administrator to get it up and running.

I’ve put this guide together to be the resource I wish I had when I first started. We’re going to skip the jargon and focus on the "why" and "how." By the end of this article, you won't just have a VM running in the cloud—you'll actually understand the settings that got you there.

Let’s dive in and get your first cloud server live!

Step 1

Type virtual machine into the search bar. Select Virtual machines from the services list to head to the compute dashboard.

Step 2

Click the + Create button in the top-left corner. Choose Azure virtual machine from the dropdown menu. This opens the main configuration form.

Step 4

Now we choose the "brain" and the "muscle" of the server. Image: Select Windows Server 2025 Datacenter: Azure Edition. Size: For a balance of performance and cost, a size like Standard_D2s_v3 or Standard_DS1_v2 is perfect for beginners.

Step 5
You wouldn't leave your front door unlocked; the same applies here.

Administrator account: Create a username (like AzureUser) and a strong password. Keep these safe! You'll need them to log in later.
Inbound port rules: To actually see your server's desktop, ensure RDP (3389) and HTTP (80) are selected. This allows you to connect remotely.

Step 6

Monitoring: Under the Monitoring tab, you can set Boot diagnostics to "Disable" for a simple lab setup to save on storage costs.

Step 7

Tags: Use the "Tags" tab to label your resources. For example, set a tag for Department: IT or Staff: [Your Name]. This is a lifesaver for tracking costs later.

Step 8
Almost there! Azure will now double-check your settings.

Click Review + create. Azure will run a "Validation" to make sure your settings are compatible. Once you see the green "Validation passed" checkmark, click the big blue Create button at the bottom.

Step 9
Once the deployment is complete, click Go to resource to open your VM’s overview page.

On the VM Overview page, you will see your Primary NIC public IP (e.g., 4.222.232.95).

Step 10

Click the Connect button at the top and select Connect.

If you see a certificate warning stating "The identity of the remote computer cannot be verified," simply click Yes to proceed.

Step 12

You are now logged into your Windows Server 2025 instance! You can verify the version by going to Settings > System > About, where you’ll see the Windows Server 2025 Datacenter Azure Edition branding and the version 24H2.

Congratulations! You’ve successfully navigated the Azure landscape to deploy, configure, and log into your very own Windows Server 2025 instance.
By following these steps, you’ve done more than just "click buttons"—you’ve provisioned enterprise-grade hardware in the cloud, managed secure networking, and explored the latest operating system Microsoft has to offer. Whether you’re using this VM as a sandbox for testing new features or as the first brick in a larger infrastructure project, you now have the foundational skills to scale up whenever you're ready.

Quick Cleanup Tip
Since this is a cloud environment, remember that costs are billed based on the time the VM is running. To keep your credits safe:

Stop the VM in the Azure Portal when you aren't using it.

Check that the status says "Deallocated" to ensure you aren't being charged for compute resources.

You’re now officially a cloud practitioner. Keep exploring, stay curious, and enjoy the power of Windows Server 2025!

Notice you can also Enable soft delete for containers.
Don’t forget to Save your changes.

Navigate to your container where you uploaded a file. Select the file you uploaded and then select Delete.

Select Delete to confirm deleting the file.

On the container Overview page, toggle the slider Show deleted blobs. This toggle is to the right of the search box.

Select your deleted file, and use the ellipses on the far right, to Undelete the file.

Refresh the container and confirm the file has been restored.

5. Turned on blob versioning to automatically track and restore previous document versions.

It’s important to keep track of the different website product document versions.

Go to the Overview blade of the storage account. In the Properties section, locate the Blob service section. Select the Versioning setting.

Ensure the Enable versioning for blobs checkbox is checked.
Notice your options to keep all versions or delete versions after.
Don’t forget to Save your changes.

In conclusion, by completing this hands-on Azure skilling project, I successfully built a high-availability Blob Storage solution that perfectly supports our rapidly expanding global company website. With geo-redundant storage ensuring reliable uptime, anonymous public access enabling fast low-latency delivery of product images, videos, marketing literature, and customer success stories to users worldwide, a dedicated container for organized assets, soft delete for quick recovery from accidental deletions, and blob versioning to preserve full document history, we've created a resilient, scalable foundation that directly addresses our mission-critical content needs.

Unlocking the Cloud: A Beginner's Guide to 7 Essential Cloud Computing Concepts

adegbola adeniyi — Sat, 07 Feb 2026 10:55:06 +0000

INTRODUCTION

Ever wonder how your favorite online services manage millions of users, stay reliably online, and roll out new features at lightning speed? The secret often lies in cloud computing—a powerful paradigm that’s reshaping the digital world. And understanding it isn’t just for IT professionals; it’s for anyone curious about the magic behind modern technology.

Let’s start with the basics.

Cloud computing is the delivery of computing services—such as servers, storage, databases, networking, software, analytics, and even artificial intelligence—over the internet (“the cloud”) rather than relying on local infrastructure. Think of it as renting IT resources on demand, with flexible, pay-as-you-go pricing.

Now, let’s break down these core ideas and explore how they power the digital experiences we rely on every day.

1. What is Virtualization?
Virtualization creates virtual versions of computing resources (like servers, storage, or networks) on top of physical hardware. It allows multiple virtual machines (VMs) to run on a single physical server, each with its own operating system and applications. A hypervisor (software layer) manages this separation.
This improves hardware utilization, enables easier management, and reduces costs.
There are two main types:

Type 1 (bare-metal, runs directly on hardware — more efficient).
Type 2 (hosted, runs on top of a host OS — easier for desktops).

2. Scalability
Scalability is the ability of a system to handle increased load by adding resources. There are two main approaches:

Vertical scaling (scaling up): Add more power (CPU, RAM) to an existing server.
Horizontal scaling (scaling out): Add more servers/instances and distribute the load.

NB
Horizontal scaling is preferred in cloud environments because it's more flexible and has fewer limits.

3. Agility
Agility refers to how quickly and easily a business or team can respond to changes, launch new features, or adapt to market needs. In cloud computing, agility comes from rapid provisioning of resources (minutes instead of weeks), self-service portals, automation, and DevOps practices.
It enables faster experimentation, shorter development cycles, and quicker time-to-market.

4. High Availability
High availability (HA) ensures a system remains operational and accessible with minimal downtime (often aiming for 99.9%+ uptime). It uses redundancy (e.g., multiple servers across availability zones), load balancers, and automatic failover to handle component failures without interrupting service.

5. Fault Tolerant
Fault tolerance goes beyond high availability — the system continues operating correctly even when one or more components fail completely, with no interruption and ideally zero data loss. It requires stronger redundancy (e.g., fully replicated systems with real-time synchronization) and is more expensive.
High availability often allows brief failover time, while fault tolerance aims for seamless continuation.

6. Global Reach
Global reach means deploying applications and services across multiple geographic regions and data centers worldwide. Cloud providers have regions and edge locations globally, allowing low-latency access, data residency compliance, disaster recovery, and serving users from the nearest location.

7. What is the difference between Elasticity and Scalability?

Scalability: Ability to increase capacity to handle growth (usually focused on scaling up/out for higher demand). It can be manual or planned.
Elasticity: Goes further — automatically and dynamically scales resources up and down in real-time based on actual demand. It matches resources precisely to workload (no over-provisioning waste), ideal for unpredictable traffic (e.g., auto-scaling groups).

Scalability is "grow when needed"; elasticity is "grow and shrink automatically and efficiently."

Bringing It All Together
These concepts are the building blocks of modern cloud infrastructure. They enable businesses of all sizes to innovate faster, serve customers globally, reduce operational costs, and build incredibly resilient and powerful applications that are always available, no matter what.

Understanding them is the first step to truly appreciating the power and potential of the cloud!
