What Is a Public?
Public cloud computing is a model where a service provider makes all resources public over the internet. Service providers like Google use the cloud to run applications such as Google Docs, Google Drive, or YouTube.
The public cloud is the most common way of implementing cloud computing, and it's best for companies that need an infrastructure to accommodate a large number of customers. This is particularly useful for projects that involve diverse organizations, such as research institutions and NGOs.
Service providers own, operate, and deliver public cloud services over the public network, often at a minimal cost or pay-per-usage model. This makes it an attractive option for businesses looking to scale up quickly.
Cloud Infrastructure
Cloud Infrastructure is a key aspect of Azure, allowing users to build, deploy, and manage applications with ease. This is made possible through Infrastructure as a Service (IaaS), which provides virtual machines, storage, and networking, but leaves application build and deployment to the user.
Azure supports a wide range of operating systems, thanks to its Hyper-hypervisor, which allows it to run multiple virtual machines at the same time. Each virtual machine can run any operating system, such as Windows or Linux.
Azure takes virtualization to a massive scale by repeating it in its data centers, which are owned by Microsoft. Each data center has many racks filled with servers, each containing a hypervisor to run multiple virtual machines.
Azure's cloud infrastructure is also characterized by its accessibility, scalability, cost-effectiveness, and security. These characteristics are essential for businesses and individuals looking to move their applications to the cloud.
Here are the key characteristics of Azure's public cloud infrastructure:
- Accessibility: Public clouds are easily accessible over the internet from anywhere, enabling convenient access to resources.
- Scalability: They offer scalability, allowing users to quickly adjust resources based on demand, ensuring efficient resource utilization.
- Cost-effectiveness: Public clouds operate on a pay-as-you-go model, reducing upfront costs and enabling cost-effective usage of resources.
- Security: Robust security measures such as encryption, access controls, and compliance certifications are implemented to protect data and infrastructure.
How It Works
Microsoft Azure is a private and public cloud platform that helps developers and IT professionals build, deploy, and manage applications. It uses virtualization technology to separate the hardware and operating system, allowing multiple virtual machines to run on a single server.
A hypervisor, also known as an abstraction layer, is used to emulate all the functions of a computer in a virtual machine. This means that each virtual machine can run any operating system, such as Windows or Linux.
Each data center owned by Microsoft has many racks filled with servers, each including a hypervisor to run multiple virtual machines. The network switch provides connectivity to all those servers, making it possible to manage and deploy applications on a massive scale.
Azure takes the virtualization technique to a massive scale, allowing for the deployment of multiple virtual machines across many servers and data centers. This scalability is what makes Azure a popular choice for businesses and developers.
Here are some key features of Azure's virtualization technique:
- Virtualization separates the hardware and operating system.
- Hypervisors emulate all the functions of a computer in a virtual machine.
- Multiple virtual machines can run on a single server.
- Each virtual machine can run any operating system, such as Windows or Linux.
Cloud Infrastructure
Cloud infrastructure is a crucial aspect of cloud computing. It refers to the underlying architecture and systems that support the delivery of cloud services.
Infrastructure as a Service (IaaS) is a type of cloud infrastructure that provides virtual machines, storage, and networking. Users have to manually build and deploy applications on IaaS, but it supports a wide range of operating systems due to its Hyper-hypervisor.
Virtualization is a key technology used in cloud infrastructure. It separates the tight coupling between hardware and operating system using an abstraction layer called a hypervisor. This allows multiple virtual machines to run on a single physical server.
Public clouds are highly accessible over the internet, enabling convenient access to resources from anywhere. They also offer scalability, allowing users to quickly adjust resources based on demand.
The pay-as-you-go model of public clouds is cost-effective, reducing upfront costs and enabling cost-effective usage of resources. Robust security measures such as encryption, access controls, and compliance certifications are implemented to protect data and infrastructure.
Azure, a popular cloud platform, takes virtualization to a massive scale in its data centers. Each data center has many racks filled with servers, each running multiple virtual machines.
