So, let us begin with the Azure definition first, which I am going to talk about in the section below.

Azure is a cloud computing platform and an online portal that allows you to access and manage cloud services and resources provided by Microsoft. Microsoft Azure was officially launched on February 1, 2010. Azure allowed users to build, test, deploy, and manage applications on the data centers of Microsoft. These data centers have been spread across 54 global regions. Microsoft offers various services across multiple domains such as computing, Database, Content Delivery, Networking, and many more.

Let us now move on, and deep-dive into Microsoft Azure. Let us start by analyzing the other Cloud Providers.

To understand what Azure Cloud is, we must also know about other cloud platforms such as Amazon Web Service (AWS) and Google Cloud Platform. Without going into details, let us just compare them to avoid confusion.

Here are some of the differences between the three cloud service providers.

Cloud Computing is still new, and there’s a lot of opportunity for professionals to grow in this field by getting the right certifications.

Azure holds the largest market share, after AWS. With the extensive use of AWS, there are many professionals who already have mastered it and the job market for AWS has now become saturated. On the other hand, opting for Google Cloud would not help you much, since most of the Fortune 500 companies are not on Google Cloud right now. Hence, the number of jobs available for Google Cloud is comparatively less. Being in the middle ground, getting certified as an Azure Professional is going to be a strategically good choice.

Now that we know learning Azure is the right thing to do, let’s move on to learn how it actually works by discussing the Microsoft Azure architecture.

Go through our blog on what is Azure Data Lake to learn in detail.

Azure Pricing

Microsoft Azure gives the most amazing pocket-friendly plans for your Infrastructure on Azure.

Pricing of Azure is offered in the following three forms:

1. Pay as you go
2. Spot Pricing or Low Priority VM
3. Azure Reserved Instances

Let us understand them one by one:

Pay as you go: It is as simple as it sounds, you pay only for what you use. For example: Let’s say you use a 64GB RAM machine with 8 CPU cores for 45 minutes. You will just be charged for 45 minutes, nothing more nothing less. Want to hear something cool? The pricing for the machine similar to this spec is as low as, 61 rupees or 0.8 US dollars an hour. Isn’t that amazing? Not impressed with this pricing? Read on.

Spot Pricing or Low Priority VM: Azure Spot Pricing and Low Priority VMs offer users a way to save up to 70% on standard Azure pricing by using unused compute capacity. Azure Spot Pricing allows users to bid on spare compute resources, while Low Priority VMs are always available at a discounted price but can be interrupted if demand for compute resources increases.

This pricing option is ideal for workloads that can be interrupted, such as batch processing jobs, dev/test environments, and large compute workloads.

Azure Reserved Instances: With Azure Reserved Instances you can avail a discount of up to 70% on standard Azure pricing. How? Well, unlike Low Priority VMs, this kind of pricing is for workloads, which are extremely important and require constant processing. The way it works is, you commit to this cloud service that you will be using a particular VM for let’s say 2 years. This way, Azure gives you an upfront discount up to 70% which can vary based on the commitment time. But, you cannot withdraw the VM mid-term. Once you have committed you will use the VM for a particular amount of time, you will be billed for the time that you committed for, even though you are not using it.
