Microsoft Azure Fundamentals is a set of three courses that help you get to know Azure and what it offers. The course has interactive exercises and a temporary Azure portal environment known as the sandbox. This course is for people who are interested in Azure or the cloud, and for those who want to get certified by Microsoft (AZ-900). You don't need to be a technical expert, but having some basic IT knowledge will make it easier for you to learn.
AZ 900 Domain Areas:
- Describe cloud concepts holds 25-30% of it's weight
- Describe Azure architecture and services holds 35-40% of it's weight
- Describe Azure management and governance holds of it's 30-35% weight
Each area of expertise corresponds to a learning path in Azure Fundamentals. The more questions related to that area will be included in the exam, the higher the percentage. This training will help you understand Azure better.Azure Fundamentals training teaches you the basics of Azure, and each area has its own learning path.
In this module, you'll learn about some basic cloud concepts, like shared responsibility, various cloud models, and the special pricing method used for the cloud. The things you will learn are what cloud computing means, how the shared responsibility model works, the different types of cloud models, when to use them, how the consumption-based model works, and how to compare cloud pricing models. Cloud computing means using the internet to access computing services like virtual machines, storage, databases, and networking. It includes new things like IoT, machine learning, and artificial intelligence in addition to the usual IT services. Cloud computing services are delivered through the internet, which means they aren't limited by physical infrastructure like a traditional datacenter.
Cloud computing lets people use computing resources like processing power and storage through a data centre provided by a cloud provider. This setup allows users to pay only for the services they need and removes the hassle of managing and maintaining their own hardware. Cloud providers mainly offer two services: computing power and storage capacity. Cloud computing lets you adjust your resources as needed, which can save you money. Cloud providers take care of maintaining, keeping backups, and keeping the infrastructure running smoothly to make sure it performs well and is always available. Cloud computing allows businesses to adjust their computing needs easily and affordably.
Shared Responsibility Model
A concept called the "Shared Responsibility Model" is used to describe how cloud computing affects network connection, electricity, cooling, and physical security. It is closely related to cloud service models like software as a service (SaaS), infrastructure as a service (IaaS), and platform as a service (PaaS). SaaS lays the majority of the duty with the cloud provider, while IaaS places it primarily with the customer. Between IaaS and SaaS, PaaS occupies a middle ground and equally divides responsibilities between the cloud provider and the consumer. This figure illustrates how, based, the Shared Responsibility Model works:
The cloud provider is always responsible for:
- The physical datacenter
- The physical network
- The physical hosts
Your service model will determine responsibility for things like:
Operating systemsYou’ll always be responsible for:
- The information and data stored in the cloud
- Devices that are allowed to connect to your cloud (cell phones, computers, and so on)
- The accounts and identities of the people, services, and devices within your organization
- Network controls
- Applications
- Identity and infrastructure
Types Of Cloud
There are three main types of cloud models: private, public, and hybrid. These models determine how cloud resources are deployed. Private clouds give companies and their IT departments more control, but they cost more and don't offer as many benefits as public clouds. Public clouds are made and taken care of by a different company, while hybrid clouds use both public and private clouds together. Azure Arc helps you manage your cloud environment, while Azure VMware Solution helps you run VMware workloads in Azure with seamless integration and scalability. Azure Arc can help you manage different types of cloud environments, such as public clouds on Azure, private clouds in your datacenter, hybrid configurations, or multi-cloud environments that run on multiple cloud providers simultaneously.
CapEX VS OpEX
The consumption-based model is a way of evaluating IT infrastructure costs. It compares two types of expenses: capital expenditure (CapEx) and operational expenditure (OpEx). Cloud computing is considered an operating expense (OpEx) because it works on a pay-as-you-go system. Cloud computing allows you to avoid paying for the physical infrastructure, electricity, security, and other costs that come with maintaining a datacenter. This way of using resources has a lot of advantages. You don't have to pay a lot of money at the beginning, you don't have to buy and take care of expensive equipment, you can pay for more resources when you need them, and you can stop paying for resources you don't need anymore. Cloud computing means using computing services over the internet and paying only for what you use.
Planning and managing operating costs, running infrastructure more efficiently, and scaling as business needs change all of them are provided for you. The cloud provider handles the maintenance of the infrastructure so that users can focus on solving their business challenges and providing innovative solutions to their customers.
