Overview of Azure Arc
Azure Arc, a powerful tool within Microsoft Azure, simplifies complex and distributed environments across on-premises, edge, and multi-cloud. It can work with any type of hardware. It registers and manages workloads using external services, even if the service runs on other public cloud platforms such as AWS and Google Cloud.
Azure Arc allows managing the following resource types:
1) Kubernetes clusters
2) Azure data services
3) Windows and Linux servers
4) Extend Azure services to Structured Query Language (SQL) Server instances outside of Azure
5) Virtual Machines (currently available to preview)
Features of Azure Arc
While building massive projects, companies need their data to be organised and managed without any complexities. Azure Arc provides various features to meet these Data Management requirements. Let's briefly look at them:
1) Users can manage an entire environment by predicting the existing non-Azure and on-premises resources in Azure Resource Manager. While introducing new DevOps practices, users can continue using traditional IT Operations (ITOps) to support new cloud-native patterns in their environment.
2) Azure Arc allows up-to-date data capacity, speedy deployment, and advanced scalability for any infrastructure. Thus, users can leverage various Azure Arc benefits regardless of their location in the world.
3) It also helps developers build containerised apps with the tools of their choice. They further ensure that the apps are installed, constructed, and organised uniformly using GitOps-based Configuration Management.
4) Through the Microsoft Azure Cloud Features, Customers get a combined and coherent view of all their Azure data services running across on-premises and clouds.
5) Users can also take advantage of its new features, such as Virtual Machine Support (VMS), a GPU-based form factor, high availability with multiple nodes, and Multi-access Edge Computing (MEC).
6) Azure Arc simplifies applying cloud security across environments with centralised role-based access control and security policies.

Benefits of Using MS Azure Arc
From building cloud-native apps to remote integration, Azure Arc has several benefits. Let’s explore some of them below:
Build Cloud-native Apps From Anywhere and Everywhere
Azure Arc employs an updated Cloud-native app development approach that helps users use DevOps techniques to install and organise Kubernetes applications at scale on any verified Kubernetes distribution of their choice. Thus, Azure Arc enables them to create cloud-native programs that run anywhere and at any scale.
Run Azure Arc Services Anywhere
Azure SQL Managed Instance and Azure PostgreSQL Hyperscale are some Azure services that can run from any location. It allows customers to use Cloud applications and automation to deliver Azure Arc-enabled data services instantly, reliably, and at scale.
Gain Central Visibility, Operations and Compliance
Azure Arc also offers a single point of control to manage all environments, regardless of whether it is on-premises or any public cloud infrastructure such as Windows, Linux, SQL Server, or Kubernetes cluster. Users can maintain consistency and administration from the central control point, i.e., Azure.

Azure Arc Use Cases
Azure Arc is the service Microsoft provides, which enlarges Azure management features to all resources everywhere, including the ones outside the Azure environment. For instance, other Clouds and on-premises platforms. This feature makes businesses more agile in managing different scales of IT resources in several environments. Undefined.
Control Sprawling IT Assets
In modern IT environments, resources like on-premises data centres and multiple Cloud providers can be spread anywhere. This scatter makes any visibility and control almost impossible.
Azure Arc also helps with bringing these disparate resources under one management umbrella. It enables admins to manage virtual machines and Kubernetes clusters and databases natively in Azure resources, irrespective of their physical location. This setup of central control reduces management overhead, improves security, and enhances operational effectiveness.
Ensure Consistent Deployment and Configuration
It is essential that throughout the deployment and configuration process in an IT environment consisting of different elements, consistency is maintained for a higher degree of operation efficiency and reliability.
Azure Arc extends Azure governance, deployment, and Configuration Management to all resources, whether deployed on other Clouds or on-premises sites. With Azure Arc, administrators can apply Azure Policy and Azure Resource Manager templates they are familiar with to ensure policy enforcement and achieve consistent settings across the platform.
With this consistency, there is a minimal risk of errors and security weaknesses, and therefore, IT management is more predictable and easier to oversee.
Meet Regulatory and Data Sovereignty Requirements
As for companies working in different states, the current legislation should be complied with, and data privacy and data sovereignty regulations are the aspects confronted the most.
Such laws often demand data storage and processing within only specified territories. Azure Arc will aid organisations in meeting the requirements, as using this technology, they can apply Azure's security and compliance policies for data and applications, regardless of their location.
The company can perform its IT operations in any environment with peace of mind because business compliance is maintained without concerns. By harnessing Azure Arc, companies can accurately and consistently tackle global legislation and the rule of data sovereignty, consequently ensuring the full performance of their IT practices.
Azure Arc-enabled Servers
Azure Arc-enabled servers that are beyond the Azure environment can oversee Windows and Linux servers, whether physical or virtual. With Azure Management Groups, businesses can efficiently manage policies and compliance across these environments. This includes servers on your corporate network or hosted with another Cloud service provider.
The user experience for managing these servers is designed to resemble how they closely manage native Azure Virtual Machines. It leverages standard Azure components such as Azure Policy and the application of tags. The following Azure Arc control plane functionalities come at no additional cost:
1) Azure Management groups and tags are employed for organising resources.
2) Azure Resource Graph is used for efficient searching and indexing.
3) Access and security are ensured through Azure RBAC and subscription mechanisms.
4) Environments and automation are facilitated via templates and extensions.
5) Update management is also included in the offering.

Azure Arc-enabled Kubernetes
Azure Arc Kubernetes connects with and configures Kubernetes operational clusters across various environments. It enables clusters to link on specific public Cloud platforms like GCP or AWS and within your on-premises data centre.
Upon connecting a Kubernetes cluster to Azure Arc, the following actions take place:
1) An Azure Resource Manager assigns a unique ID.
2) It is associated with an Azure subscription and allocated to a resource group.
3) Tags are applied in the same manner as with any other Azure resource.
For enhanced security, an industry-standard Secure Sockets Layer (SSL) is employed to protect data in transit within Kubernetes. Data at rest for connected clusters, cluster extensions, and custom locations is encrypted and stored securely in an Azure Cosmos DB database to maintain confidentiality.
Azure Arc-enabled VMware vSphere
The Azure Arc preview for VMware ESX vs. ESXi within Virtual Machineware (VMware) vSphere, powered by VMware vSphere, extends Azure's governance and management capabilities to your VMware vSphere infrastructure. This integration ensures a seamless management experience across both Azure and VMware vSphere environments. With Azure Arc-enabled VMware vSphere, users can:
a) Directly execute VMware Virtual Machine lifecycle operations like VM creation, starting/stopping, resizing, and deletion from Azure.
b) Utilise Azure's role-based access control to empower developers and application teams to perform on-demand VM actions.
c) Access and view their VMware vSphere resources within the Azure portal, including VMs, templates, networks, and storage. This provides a unified view of the infrastructure in both environments through a single interface. Pre-existing VMware VMs can be discovered and integrated with Azure.
d) Users can carry out governance and monitoring actions across Azure and VMware Virtual Machines (VMs) by enabling guest management.

Azure Arc Architecture
It functions as an extension of the Azure Control Plane. Azure manages the life cycle of a diverse range of resources, encompassing Virtual Machines, Hadoop clusters, and Kubernetes clusters. The pivotal component of Azure's Control Plane is the Azure Fabric Controller. Virtually every Azure resource communicates its actions and events to this Control Plane.
Next is the Azure Resource Manager (ARM), between the fabric controller and the resources. It is responsible for automating the complete life cycle of these resources.
Each service within Azure has its dedicated resource provider. Its examples include SQL Database, Azure Kubernetes Service, and Virtual Machines.
Does Azure Arc Require an Azure Subscription?
Yes, an Azure subscription is required to onboard and manage non-Azure resources using Azure Arc. However, organisations pay only for the specific Azure services they use.
Is Azure Arc Suitable for Small Businesses?
Yes. Azure Arc provides flexible hybrid cloud management, making it ideal for businesses of all sizes looking for centralised security, automation, and cost-effective cloud governance.
