Unlocking the Core Azure Services on the Road to AZ-900
Well, well, well, prepare for a treat! We're peeling back the layers of the Microsoft Azure onion to expose its core. The purpose of this blog is to help you better understand the core Azure services, an essential topic for the Microsoft Azure Fundamentals AZ-900 exam. Grab a cup of coffee, get comfy and let's dive straight in, shall we?
Introduction to Azure Services
How can I best describe Azure? I'd say, it's like a big, bustling city, full of varied, yet interconnected services, each with a different, yet crucial, role to play. And these services are exactly what we'll be blabbing about today.
Compute Services
You've probably heard the saying, "You're never fully dressed without a smile", right? Well, in the world of Azure, I'd say you're never fully operational without computation. Compute services are the heart and soul of Azure, providing the raw processing power that enables everything else to, well, compute!
Among the star players of Azure's compute services, we have Virtual Machines (VMs), Azure Functions, and Azure Kubernetes Service (AKS). VMs are, of course, the solid foundation, providing everything from humble single-core machines to powerhouses with a whopping 128 vCPUs and 4TB RAM. Wowza! Now, that's some serious muscle!
Networking Services
The next stop on our tour through the Azure city is the networking neighborhood. Just as roads in a city, networking services like Virtual Network, Load Balancer, and VPN Gateway ensure everything and everyone in Azure can communicate smoothly, swiftly, and securely. As the saying goes: No man, or in this case, service, is an island. Networking makes sure of that.

Storage Services
An examination of Azure's core services would be incomplete without discussing its storage services, whose architecture is as crucial and intricate as the foundations of a skyscraper. Azure offers a variety of storage options, including Blob Storage, Queue Storage, File Storage, and Disk Storage, each fulfilling a distinct and fundamental role in Azure's overall infrastructure.
You can use Blob Storage as a cost-effective, high-scale solution to store heaps of unstructured data, such as text or binary data. Alternatively, Queue Storage primarily stores and retrieves massive volumes of messages, promoting smooth communication between different application components. Disk storage supplies highly durable and hyper-scalable storage for use with Azure VMs.
In a decidedly academic manner, it is also appropriate to explore Microsoft's commitment to data integrity, resilience, and accessibility, demonstrated through its incorporation of redundancy options within its storage service. Azure provides three primary data replication options: Locally redundant storage (LRS), Zone-redundant storage (ZRS), and Geo-redundant storage (GRS).

Web and Mobile Services
Now, let's step into the fun part! If Azure was an amusement park, Azure App Service - a platform that enables the building and hosting of web applications in various programming languages without infrastructure worries - would be the roller coaster. Thrilling yet secure, it's the service that makes the heart of many developers skip a beat or two.
And let's not forget about Azure Notification Hubs, the loudspeaker of the Azure park. It sends out push notifications to any platform- iOS, Android, Windows, you name it! And if you want to build, test, and distribute apps to beta testers and users more smoothly with powerful CI/CD capabilities, you head to the Azure DevOps corner of the park.

Be Impressed: Azure By the Numbers
Alright, now that we've painted quite the picture of Azure's core services, it's time to blow your mind with some stats! Hang onto your hats because these numbers don't mess around.
First off, Azure is a juggernaut with a presence in no less than 60 regions worldwide. That's like saying Azure is in more places than Starbucks! It includes over 200 services - a figure that's steadily on the rise.
And, consider this - 95% of Fortune 500 companies trust their business on Azure. It's not merely a big slice of the pie; it's more like the entire darn pie! Moreover, with many services offering a Service Level Agreement (SLA) of up to 99.99%, Azure demonstrates near-absolute reliability!
Wrapping Up
Suffice to say, understanding Azure's core services - compute, networking, storage, web and mobile - is like holding the key to the vast and vibrant Azure city. Whether you end up becoming its mayor or just a friendly local, there's no limit to what you can achieve in this city.
Whether you're an IT beginner poised to sample the Azure waters, or a seasoned pro prepping for your AZ-900 exam, make sure the journey delights you as much as the destination. After all, isn't a ride all about having a bit of fun, eh?
