Some of the key features of Azure Public Cloud include:

Azure Public Cloud is a robust and feature-rich platform that can help businesses of all sizes build and deploy scalable and secure applications and services.

Azure public cloud offers three main types of services: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These services allow you to provision and use processing power, storage, and networking resources on demand.

With IaaS, you can build your own architecture from infrastructure-as-a-service products, such as Azure Virtual Networks, Azure VMs, and Azure Disc Storage. This allows for a high level of customization and control.

The three types of cloud computing services - IaaS, PaaS, and SaaS - differ mainly on how much you manage versus how much the cloud vendor manages. Here's a brief overview of each:

In addition to these service types, there are four main deployment models for cloud computing: public, private, hybrid, and community.

Microsoft Azure works by using virtualization to separate the hardware and operating system, allowing multiple virtual machines to run on a single server. This abstraction layer is called a hypervisor.

Each virtual machine can run any operating system, such as Windows or Linux, making it a versatile platform for developers and IT professionals.

The hypervisor is a key component of Azure's architecture, emulating all the functions of a computer in a virtual machine.

Multiple virtual machines can run at the same time, making it an efficient use of resources.

Cloud computing has revolutionized the way businesses operate, providing flexibility and scalability that was previously unimaginable. There are three main types of cloud computing services: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

IaaS allows you to provision and use processing power, storage, and networking resources on demand. This model provides a high level of control over the infrastructure, but also requires more management and maintenance.

PaaS, on the other hand, allows you to develop, run, and manage applications without worrying about the underlying infrastructure. This model is ideal for developers who want to focus on building applications without the hassle of managing servers and storage.

SaaS delivers software over the internet and makes it available through web browsers or mobile apps. This model is perfect for businesses that want to use software without the need to install or maintain it locally.

Here are the main differences between the three cloud service models:

Azure offers a range of services under the PaaS model, including Azure app service, Azure functions, and logic apps. These services provide autoscaling and load balancing, as well as a pre-configured environment for the application.

Software as a service (SaaS) is a model where the application is managed by the provider, including deploying, scaling, and load balancing.

Microsoft Azure offers services like Office 365, Dynamics 365, and Azure Active Directory under SaaS, where the complete application is managed by Microsoft Azure.

Each application is self-standing, but resources like Microsoft Azure can help in the process of construction, including deploying, scaling, and load balancing.

Spot Instances are a great way to save money on your cloud computing costs. They allow you to purchase unused Azure capacity at a significant discount.

You're billed per minute for Spot Instances, which can be a cost-effective option for workloads that can tolerate interruptions.

Workloads that can take advantage of Spot Instances include batch processing jobs, dev/test environments, and large computations.

Azure is the No. 2 public cloud provider, just behind market leader Amazon Web Services (AWS). It has been growing rapidly since its creation in 2008.

As of the second quarter of 2021, AWS controlled 31% of the market, Microsoft Azure took 22%, and Google Cloud sat at 8% market share — according to Statista. This shows that Azure is gaining ground in the cloud market.

Microsoft Azure has a strong presence in the enterprise space, with 95% of Fortune 500 companies using Azure. This is a testament to its popularity and reliability.

Azure adoption is increasing in enterprises while AWS adoption remains relatively flat — according to Flexera. This suggests that Azure is becoming the preferred choice for many businesses.

Azure services can vary by region, so it's essential to know what's available in your area.

Some services require more resources than others, which is why not all services are offered in all regions.

Most regions will have most of the Azure service catalog on offer, but a few exotic services like Azure Machine Learning are sometimes only offered in one region within each geography.

Not all regions are created equal, and some have a more limited selection of services due to their status as government regions or newly established regions.

Azure public cloud is a robust and scalable platform that offers a wide range of features and benefits. Its key characteristics include accessibility, scalability, cost-effectiveness, and robust security measures.

Azure provides easy access to resources over the internet from anywhere, making it convenient for users to access resources on demand. This is especially useful for businesses that need to quickly scale up or down to meet changing demands.

Azure operates on a pay-as-you-go model, reducing upfront costs and enabling cost-effective usage of resources. This is a significant advantage over traditional on-premises infrastructure, where businesses often have to invest in expensive hardware and software.

Azure offers robust security measures such as encryption, access controls, and compliance certifications to protect data and infrastructure. This ensures that sensitive information is kept safe and secure, even in the event of a disaster.

Here are some of the key features of Azure:

Azure also offers a range of services for data analytics, including distributed analytics, storage, real-time data analysis, and streaming. This makes it an ideal platform for businesses that need to process and analyze large amounts of data.

Azure Security is a comprehensive set of tools and features designed to protect Microsoft's cloud services. It encompasses physical, infrastructure, and operational controls to ensure the security of Azure's services and resources.

Azure Security employs a shared security responsibility model, where security is a collaborative effort between Azure and its customers. This model varies across different cloud service models, with customers retaining more responsibilities in Infrastructure as a Service (IaaS) compared to Platform as a Service (PaaS) or Software as a Service (SaaS).

In IaaS, Azure assumes responsibility for physical security, including hosts, networks, and data centers. In PaaS, Azure manages physical security and the operating system, while customers share responsibilities for identity and directory infrastructure, network controls, and applications. In SaaS, Azure takes on even more responsibilities, including physical security, operating systems, network controls, and applications.
