By adopting Azure Arc, businesses can address the challenges posed by multi-cloud and hybrid environments. This powerful tool not only simplifies management but also empowers organizations to embrace modern, cloud-native approaches while maintaining control over their diverse IT landscapes.
Presently, Azure Arc offers the capability to manage a variety of resource types that are located outside of the Azure cloud environment. Let’s explore these resource types in more detail:
Servers: Azure Arc-enabled servers
Azure Arc-enabled servers allow you to efficiently manage Windows and Linux physical servers, as well as virtual machines, situated outside of Azure, including those on your corporate network or in other cloud providers, treating them as hybrid machines, and providing consistency in management through standard Azure constructs like Azure Policy and tags.
To connect hybrid machines to Azure, you install the Azure Connected Machine agent on each machine. Azure Monitor Agent for Windows and Linux is required for the following purposes:
• Proactive Monitoring: It enables proactive monitoring of both the operating system (OS) and workloads running on the machine, ensuring that you can keep a close eye on their performance and health.
• Management with Automation: You can manage the machine using Automation runbooks or solutions such as Update Management, streamlining maintenance tasks and ensuring that your systems stay up to date.
• Integration with Azure Services: It allows seamless integration with various Azure services, including Microsoft Defender for Cloud, enhancing your security and compliance capabilities within the Azure ecosystem.
When you connect your machine to Azure Arc-enabled servers, you can perform a range of operational functions, similar to native Azure virtual machines. These actions include:
Govern:
• Assign Azure Automanage machine configurations to audit settings within the machine..
Protect:
• Safeguard non-Azure servers using Microsoft Defender for Endpoint, which is included through Microsoft Defender for Cloud. This provides threat detection, vulnerability management, and proactive monitoring for potential security risks. Alerts and remediation suggestions for detected threats are presented through Microsoft Defender for Cloud.
• Utilize Microsoft Sentinel to gather security-related events and correlate them with other data sources.
Configuration:
• Utilize Azure Automation for managing tasks with PowerShell and Python runbooks.
• Assess configuration changes for software, Microsoft services, Windows registry, files, and Linux daemons via Change Tracking and Inventory.
• Manage operating system updates with Update Management for Windows and Linux servers. Automate onboarding and configuration using Azure Automanage (preview).
• Perform post-deployment configuration and automation using supported Arc-enabled servers VM extensions for non-Azure Windows or Linux machines.
Monitoring:
• Monitor OS performance and discover application components, tracking processes and dependencies with VM insights.
• Collect additional log data like performance metrics and events from the OS or workloads using the Log Analytics agent, which stores data in a Log Analytics workspace.
Kubernetes clusters: Azure Arc-enabled Kubernetes
Azure Arc-enabled Kubernetes simplifies the management of Kubernetes clusters, no matter where they are running. You can connect and control these clusters within Azure, ensuring a consistent experience for developing and operating cloud-native applications across various Kubernetes platforms and locations.
When Azure Arc agents are installed on a cluster, they establish a secure connection to Azure using SSL encryption to protect data while it travels over the network.
Once connected to Azure, these clusters become distinct resources in Azure Resource Manager. This means you can organize and manage them alongside your other Azure resources using resource groups and tags for better organization and control.
Once your Kubernetes clusters are linked to Azure, you can efficiently manage them at scale by:
• Inventory and Organization: Easily view and organize all connected Kubernetes clusters, both those outside of Azure and Azure Kubernetes Service (AKS) clusters, making it simpler to manage your resources.
• Configuration Management: Configure clusters and deploy applications using GitOps-based configuration management, streamlining the deployment and management of your applications.
• Monitoring: Keep an eye on your clusters using Azure Monitor for containers, ensuring you have insights into their performance and health.
• Security: Enhance security by enforcing threat protection with Microsoft Defender for Kubernetes, helping safeguard your clusters from potential threats.
• Governance: Apply policies to ensure compliance and governance through Azure Policy for Kubernetes, ensuring that your clusters adhere to your organization’s rules and standards.
• Access Control: Manage access to your Kubernetes clusters from anywhere and control it using Azure role-based access control (RBAC), enhancing security and access management.
• Machine Learning: Deploy machine learning workloads seamlessly using Azure Machine Learning for your Kubernetes clusters, opening up possibilities for advanced data analysis and modeling.
• Specialized Services: Deploy services tailored to your specific needs, whether it’s utilizing particular hardware, complying with data residency regulations, or enabling new functionalities. Examples of such services include Azure Arc-enabled data services, Event Grid on Kubernetes, and App Services on Azure Arc.
In a nutshell, Azure Arc enables you to efficiently manage, monitor, secure, and govern your Kubernetes clusters while offering the flexibility to deploy specialized services and leverage advanced capabilities for your workloads.
