Azure Arc extends Azure Resource Manager capabilities to Linux and Windows servers, as well as Kubernetes clusters on any infrastructure across on-premises, multi-cloud, and edge. With Azure Arc, customers can also run Azure data services anywhere, realizing the benefits of cloud innovation, including always up-to-date data capabilities, deployment in seconds (rather than hours), and dynamic scalability on any infrastructure. Azure Arc for servers is currently in public preview.
Arc Overview
https://docs.microsoft.com/en-us/azure/azure-arc/servers/overview
Azure Arc for servers (preview) allows you to manage your Windows and Linux machines hosted outside of Azure on your corporate network or other cloud provider, similarly to how you manage native Azure virtual machines. When a hybrid machine is connected to Azure, it becomes a connected machine and is treated as a resource in Azure. Each connected machine has a Resource ID, is managed as part of a resource group inside a subscription, and benefits from standard Azure constructs such as Azure Policy and applying tags.
To deliver this experience with your hybrid machines hosted outside of Azure, the Azure Connected Machine agent needs to be installed on each machine that you plan on connecting to Azure. This agent does not deliver any other functionality, and it doesn't replace the Azure Log Analytics agent. The Log Analytics agent for Windows and Linux is required when you want to proactively monitor the OS and workloads running on the machine, manage it using Automation runbooks or solutions like Update Management, or use other Azure services like Azure Security Center.

Azure Arc delivers three capabilities - managing VMs running outside of Azure, registering and managing Kubernetes clusters deployed within and outside of Azure and running managed data services based on Azure SQL and PostgreSQL Hyperscale in Kubernetes clusters registered with Azure Arc.
As of Build 2020, Microsoft has opened up the first two features of Azure Arc - management of VMs and Kubernetes clusters running outside of Azure. Azure Arc enabled data services is still in private preview.
Adding machines to a group and defining in policies
The Connected Machine agent can be deployed in a variety of OS environments including Windows Server 2012 R2 or higher, Ubuntu 16.04, SUSE Linux Enterprise Server 15, Red Hat Enterprise Linux 7, and even Amazon Linux 2.
The registered machines are listed in the same Azure resource group that has native Azure VMs running in the public cloud. Customers can apply labels to any VM in the resource group to include or exclude them in a policy. Participating machines can be audited by an Azure Policy and an action can be taken based on the outcome.

Arc Agent on each machine or node
The Connected Machine agent sends a regular heartbeat message to the service every 5 minutes. If the service stops receiving these heartbeat messages from a machine, that machine is considered offline and the status will automatically be changed to Disconnected in the portal within 15 to 30 minutes. Upon receiving a subsequent heartbeat message from the Connected Machine agent, its status will automatically be changed to Connected.

Arc can manage Kubernetes Clusters
Similar to how VMs can be onboarded to Azure, Kubernetes clusters can be brought into the fold of Azure Arc.
Customers can attach Kubernetes clusters running anywhere outside of Azure to Azure Arc. This includes bare-metal clusters running on-premises, managed clusters such as Amazon EKS and Google Kubernetes Engine, and enterprise PaaS offerings such as Red Hat OpenShift and Tanzu Kubernetes Grid.
Similar to the Connected Machine agent pushed to a VM, Azure Arc deploys an agent under the azure-arc namespace. It does exactly what the VM agent does - watch for configuration requests. Apart from that, the Arc agent running in a Kubernetes cluster can send telemetry to Azure Monitor. The telemetry includes inventory, Kubernetes events, container std{out; err} logs, and node, container, Kubelet, and GPU performance metrics.
Once the agent is deployed in a Kubernetes cluster, it can participate in the GitOps-based configuration management and policy updates
Azure Arc-enabled Kubernetes ensures that the workloads match the desired state of the configuration by monitoring the drift and automatically applying the required changes.
Azure Arc-enabled Kubernetes comes with three capabilities:
Global inventory management - You can onboard all the Kubernetes clusters irrespective of their deployment location to manage them from a single location.
Centralized workload management - With Azure Arc, it is possible to roll out applications and configuration to hundreds of registered clusters with one commit to the source code repository.
Policy-driven cluster management - Ensure that the cluster runs the policies by centrally governing and auditing the infrastructure.
Microsoft has partnered with Red Hat, SUSE, and Rancher to officially bring OpenShift, SUSE CaaS and Rancher Kubernetes Engine to Azure Arc.
Microsoft scores additional points for adopting the open source Flux project as the choice of GitOps tool for Azure Arc. It brings transparency to the platform while providing confidence to users.
Azure Arc for Data Services in K8s
With Azure Arc for data services, customers will benefit from the ability to run managed database services in any Kubernetes cluster managed by Azure Arc. This capability will emerge as the key differentiating feature of Azure Arc.
