Microsoft Azure Tutorial for Beginners: Learn in 1 Day
Before we learn Azure, let's understand
What is Cloud Computing?
Cloud computing is a term referred to storing and accessing of data over the internet. It doesn't store any data on the hard disk of your personal computer. In cloud computing, you access data from a remote server.
What is Microsoft Azure?
Azure is a cloud computing platform which was launched by Microsoft in February 2010. It is an open and flexible cloud platform which helps in development, data storage, service hosting, and service management. The Azure tool hosts web applications over the internet with the help of Microsoft data centers.
There are mainly three types of clouds in Microsoft Azure are:
Azure as IaaS
IaaS(Infrastructure as a Service) is the foundational cloud platform layer. This Azure service is used by IT administrators for processing, storage, networks or any other fundamental computer operations. It allows users to run arbitrary software.
It offers efficient design time portability
It is advisable for the application which needs complete control
IaaS offers quick transition of services to clouds
The apparent benefit of laaS is that it frees you from the concerns of setting up many physical or virtual machines.
Helps you to access, monitor and manage datacenters
Disadvantages of Iaas:
Plenty of security risks from unpatched servers
Some companies have defined processes for testing and updating on-premise servers vulnerabilities. This cannot be done with Azure.
Azure as PaaS
PaaS is a computing platform which includes an operating system, programming language execution environment, database or web services. This Azure service is used by developers and application providers.
As its name suggests, this platform is provided to the client to develop and deploy software. It allows the client to focus on application development instead of worrying about hardware and infrastructure. It also takes care of operating systems, networking and servers issues.
The total cost is low as the resources are allocated on demand and servers are automatically added or subtracted.
Azure is less vulnerable because servers are automatically checked for all known security issues
The entire process is not visible to the developer, so it does not have a risk of a data breach
Portability issues can occur when you use PaaS services
There may be different environment at Azure, so the application needs to adapt accordingly.
Azure As SaaS
SaaS (Software as a Service) is software which is centrally hosted and managed. It is a single version of the application is used for all customers. You can scale out to multiple instances. This helps you to ensure the best performance in all locations. The software is licensed through a monthly or annual subscription. MS Exchange, Office, Dynamics are offered as a SaaS
Azure key Concepts
Azure is a global cloud platform which is available across various regions around the world. When you request a service, application, or VM in Azure, you are first asked to specify a region. The selected region represents datacenter where your application runs.
In Azure, you can deploy your applications into a variety of data centers around the globe. So, it is advisable to select a region which is closer to most of your customers. It helps you to reduce latency in network requests.
The Azure portal is a web-based application which can be used to create, manage and remove Azure resource and services. It is located at https://portal.azure.com.
Azure resource is an individual computer, networking data or app hosting services which charged individually. Some common resources are virtual machines( VM), storage account, or SQL databases.
An Azure resource group is a container which holds related resource for an Azure solution. It may include every resource or just resource which you wants to manage.
Resource Manager templates
It is a JSON which defines one or more resource to deploy to a resource group. It also establishes dependencies between deployed resources.
Azure allows you to automate the process of creating, managing and deleting resource by using PowerShell or the Azure command-line Interface(CLI).
PowerShell is a set of modules that offer cmdlets to manage Azure. In most cases, you are allowed to use, the cmdlets command for the same tasks which you are performing in the Azure portal.
Azure command-line interface(CLI)
The Azure CLI is a tool that you can use to create, manage, and remove Azure resources from the command line.
Azure is built on a set of REST APIs help you perform the same operation that you do in Azure portal Ul. It allows your Azure resources and apps to be manipulated via any third party software application.
Azure Domains (Components)
It offers computing operations like app hosting, development, and deployment in Azure Platform. It has the following components:
Virtual Machine: Allows you to deploy any language, workload in any operating system
Virtual Machine Scale Sets: Allows you to create thousands of similar virtual machines in minutes
Azure Container Service: Create a container hosting solution which is optimized for Azure. You scale and arrange applications using Kube, DC/OS, Swarm or Docker
Azure Container Registry: This service store and manage container images across all types of Azure deployments
Functions: Let's you write code regardless of infrastructure and provisioning of servers. In the situation when your functions call rate scales up.
Batch: Batch processing helps you scale to tens, hundreds or thousands of virtual machines and execute computer pipelines.
Service Fabric: Simplify microservice-based application development and lifecycle management. It supports Java, PHP, Node.js, Python, and Ruby.
Azure store is a cloud storage solution for modern applications. It is designed to meet the needs of their customer's demand for scalability. It allows you to store and process hundreds of terabytes of data. It has the following components:
Blob Storage: Azure Blob storage is a service which stores unstructured data in the cloud as objects/blobs. You can store any type of text or binary data, such as a document, media file, or application installer.
Queue Storage: It provides cloud messaging between application components. It delivers asynchronous messaging to establish communication between application components.
File Storage: Using Azure File storage, you can migrate legacy applications. It relies on file shares to Azure quickly and without costly rewrites.
Table Storage: Azure Table storage stores semi-structured NoSQL data in the cloud. It provides a key/attribute store with a schema-less design
This category includes Database as a Service (DBaaS) which offers SQL and NoSQL tools. It also includes databases like Azure Cosmos DB and Azure Database for PostgreSQL. It has the following components:
SQL Database: It is a relational database service in the Microsoft cloud based on the market-leading Microsoft SQL Server engine.
DocumentDB: It is a fully managed NoSQL database service which is It built for fast and predictable performance and ease of development.
Redis Cache: It is a secure and highly advanced key-value store. It stores data structures like strings, hashes, lists, etc.
Content Delivery Network
Content Delivery Network (CDN) caches static web content at strategically placed locations. This helps you to offer speed for delivering content to users. It has the following components:
VPN Gateway: VPN Gateway sends encrypted traffic across a public connection.
Traffic Manager: It helps you to control and allows you to do the distribution of user traffic for services like WebApps, VM, Azure, and cloud services in different Datacenters
Express Route: Helps you to extend your on-premises networks into the Microsoft cloud over a dedicated private connection to Microsoft Azure, Office 365, and CRM Online.
Security + Identify sevices
It provides capabilities to identify and respond to cloud security threats. It also helps you to manage encryption keys and other sensitive assets. It has the following components:
