What are Availability Set, Fault Domain, and Update Domain in Azure?

Table Of content 1- Availability Set 3- Fault Domain 2- Update Domain Availability Set Before understanding Availability Set, we have to understand some scenarios that can lead to the virtual machine in Azure being impacted. There are three factors that impact VM on Azure are Unplanned Hardware maintenance Event, Unexpected Downtime, and Planned maintenance event. Unplanned Hardware maintenance Event occurs when the Azure platform evaluated that hardware or a component associated with a physical machine is in a failure condition. When this event occurs, Azure issue an unplanned hardware maintenance event to reduce the impact on the virtual machines hosted on that hardware. Azure uses live migration technology to migrate the Virtual Machine from the failing hardware to a healthy physical machine. It takes a few times to be up. Memory, Open files, and network connections are maintained, but performance might be reduced before/after an event. An Unexpected down

How to create Storage Account in Azure portal

In this article, we will learn how to create a storage account on the Azure portal. Prerequisite There are some requirements before you start. You have to take a subscription to Azure. You can create your free account on Microsoft Azure using the link. After your subscription please log in to the Azure portal, and now you are ready to create your Storage account. Please follow the below steps. 1-   Create a resource group if you did not create, or you can use an existing group. 2-    In the Azure portal, select the all services and type Storage Account in the list resources, as you typing, the list filters based on your input. 4-  On the Storage Accounts window that appears, choose Add+ 5- A new window will open as below where you will found four tabs like Basic, Advanced, Tags, and Review + Create 6-   Select the subscription in which create to Storage Account, there are two types of subscription

Introduction to blob storage

Azure blob storage is optimized for storing massive amounts of unstructured data, Azure blob storage provides the object storage solution for the cloud . Azure blob storage can store any type of data like text, file, objects, binary, etc. Blob storage is designed for: 1- Serving images or documents directly to a browser. 2- Storing files for distributed access. 3- Streaming video and audio. 4- Writing to log files. 5- Storing data for backup and restore, disaster recovery, and archiving. 6- Storing data for analysis by an on-premises or Azure-hosted service. You can easily access the object in blob storage via HTTP/HTTPS, from anywhere. You can also access objects through Azure Storage REST API, Azure PowerShell, Azure CLI, or an Azure Storage client library. Here client library means the language/platform like .NET, Node.js, Python, Go, PHP, and Ruby, etc. Types of Blob storage Block blobs store text and binary data, up to about 4.7 TB. Block blobs a

Introduction to Azure Storage

Computer data storage is a device underlying computing hardware that is used for storing, porting and extracting data files and Objects. It can hold and store information both temporarily and permanently and can be internal or external to a computer, server or any similar computing device. Azure cloud storage is a service which is highly available, secure, durable, scalable, and redundant provided and managed by a Microsoft. Azure Storage includes Blobs, Files, Queues, and Tables type storage. This article will make you aware of the storage services which are provided by Microsoft Azure. Durable and highly available: It is the big deal to ensure your data is safe in the event of transient hardware, On-premise server often faces this issue and result loss of data. Microsoft Azure provides the facility of redundancy, which ensures that your data is safe in the event of transient hardware failures. You can replicate the data across the datacenters or geographical regions for add

Microsoft Azure- Availability Zones

Cloud computing is known for high-availability and low latency, so cloud computing providers are made available solution for mission-critical applications which is not possible to handle all thing from one data-center to all over world that's why cloud computing providers set up the datacenter  in different regions, and datacenter is the setup of computing machines and networking. More than one datacenter equipped with independent power, cooling, and networking, which is called the Availability Zone. Availability Zones are the combination of the data-center where data -centers are equipped with independent power, cooling, and networking, which protects your applications from datacenter failure. Why needed Availability Zones in Microsoft Azure. 1- If you select any region to set up your environment to ensure resiliency, Azure provides three separates zones in all enables regions. 2- The physical separation of Availability Zones within a region protects applications

Microsoft Azure- Regions and Datacenters

Microsoft Azure has data-centers all over the world from where azure services are managed. Data-center is the hub of computing and network from where Microsoft Azure provides its services. When I started to study the cloud, one question always hits in my mind how to Microsoft is managed the services or how to provides cloud services, a pic of large data-center come in my mind, a large building, large machines, etc. But I was wrong Microsoft has more data-centers in the global region that offering the scale needed to bring applications closer to users around the world. A region is a set of data centers deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.   More than one datacenter equipped with independent power, cooling, and networking, which is called  Availability Zones . Microsoft has 54 azure regions, available in 140 countries and up to 1.6 Pbps of the bandwidth of in a region. Following ar
