Learn Azure in a Month of Lunches breaks down the most important Azure concepts into bite-sized lessons with exercises and labs—along with project files available in GitHub—to reinforce your skills. Learn how to:
Use core Azure infrastructure and platform services—including how to choose which service for which task.
Plan appropriately for availability, scale, and security while considering cost and performance.
Integrate key technologies, including containers and Kubernetes, artificial intelligence and machine learning, and the Internet of Things.
Get best practices on how to monitor your Kubernetes clusters from field experts in this episode of the Kubernetes Best Practices Series. In this intermediate level deep dive, you will learn about monitoring and logging in Kubernetes from Dennis Zielke, Technology Solutions Professional in the Global Black Belts Cloud Native Applications team at Microsoft.
Multi-cluster view from Azure Monitor
Azure Monitor provides a multi-cluster view showing the health status of all monitored AKS clusters deployed across resource groups in your subscriptions. It shows AKS clusters discovered that are not monitored by the solution. Immediately you can understand cluster health, and from here you can drill down to the node and controller performance page, or navigate to see performance charts for the cluster. For AKS clusters discovered and identified as unmonitored, you can enable monitoring for that cluster at any time.
Container Live Logs provides a real-time view into your Azure Kubernetes Service (AKS) container logs (stdout/stderr) without having to run kubectl commands. When you select this option, new pane appears below the containers performance data table on the Containers view, and it shows live logging generated by the container engine to further assist in troubleshooting issues in real time.
Live logs supports three different methods to control access to the logs:
AKS without Kubernetes RBAC authorization enabled
AKS enabled with Kubernetes RBAC authorization
AKS enabled with Azure Active Directory (AD) SAML based single-sign on
You even can search in the Container Live Logs for Troubleshooting and history.

The Azure DevOps ecosystem also provides support for adding extensions and integrating with other popular services, such as: Campfire, Slack, Trello, UserVoice, and more, and developing your own custom extensions.
Azure Monitor for containers is a feature designed to monitor the performance of container workloads deployed to either Azure Container Instances or managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Monitoring your containers is critical, especially when you’re running a production cluster, at scale, with multiple applications.
Azure Monitor for containers gives you performance visibility by collecting memory and processor metrics from controllers, nodes, and containers that are available in Kubernetes through the Metrics API. Container logs are also collected. After you enable monitoring from Kubernetes clusters, these metrics and logs are automatically collected for you through a containerized version of the Log Analytics agent for Linux and stored in your Log Analytics workspace.
What I really like is that you now can see the Container Live logs from the Azure portal and see what is going on in the background of a Container 🙂
Activate Azure Kubernetes Container Live Logs
Here you see the Container Live logs
This feature provides a real-time view into your Azure Kubernetes Service (AKS) container logs (stdout/stderr) without having to run kubectl commands. When you select this option, new pane appears below the containers performance data table on the Containers view, and it shows live logging generated by the container engine to further assist in troubleshooting issues in real time.
Live logs supports three different methods to control access to the logs:
AKS without Kubernetes RBAC authorization enabled
AKS enabled with Kubernetes RBAC authorization
AKS enabled with Azure Active Directory (AD) SAML based single-sign on
You even can search in the Container Live Logs for Troubleshooting and history :
Search on ssh
Azure Monitor for containers uses a containerized version of the Log Analytics agent for Linux. After initial deployment, there are routine or optional tasks you may need to perform during its lifecycle.
Because of this agent you can work with Log Analytics in Azure Monitor :
When you have your production workload running on Azure Kubernetes Clusters, It’s important to monitor to keep you in Control of the solution in Microsoft Azure and watch for improvements like performance for the business. With Container Live logs you can see what is going on in the Containers when you have issues and that’s great for troubleshooting to get your problem solved fast. Get your workload into Azure Containers and make your Azure DevOps CI/CD Pipelines in the Cloud.
When you are implementing your Microsoft Azure Design like a HUB-Spoke model you have to deal with security of your Azure environment (Virtual Datacenter). One of them are Network Security Groups to protect your Virtual networks and make communication between Azure subnets possible in a Secure Azure Virtual Datacenter.
You really have to plan your Azure Virtual networks and implement it by Architectural Design. Now I’m writing about Azure Network Security Groups which is important, but there are more items to deal with like :
Naming Conventions in your Azure Virtual Datacenter
Azure Subscriptions ( who is Owner, Contributor, or Reader? )
Azure Regions ( Where is my Datacenter in the world? )
Azure VNET and Sub-Nets ( IP-addresses )
Security of your Virtual Networks ( Traffic filtering, Routing )
How to Manage Microsoft Azure Network Security Groups (NSG) ?
IMPORTANT: Before you start with Azure Network Security Groups, test every ARM JSON Script first in your Dev-Test Azure Subscription before you do production. Talk with your Cloud Administrators, because when you implement Infrastructure as Code (IaC) and work with ARM Templates you can delete manual settings in NSG’s for example, which will give you troubles like no protocol communication between subnets.
When you start new in Microsoft Azure, It’s easy to make your Azure security baseline for all of your Network Security Groups (NSG’s) by Azure Resource Manager (ARM) templates.
When you have a Microsoft Azure HUB-Spoke model with for example four Azure Subscriptions and a lot of Azure Virtual Networks – Subnets, you got a lot of NSG’s to manage and you don’t want to manage those manually. So there are different ways to manage Azure Network Security Groups via ARM Templates. For example :
ARM Templates from the Azure Portal
Make your ARM Baseline template.
Edit your parameters and Deploy.
Here you saw a standard Virtual Machine Deployment, but you can add of course all of your Azure Resource Manager templates here including your NSG Base Line template. In this way your deployments are documented ( Scripts).

The Azure DevOps ecosystem also provides support for adding extensions and integrating with other popular services, such as: Campfire, Slack, Trello, UserVoice, and more, and developing your own custom extensions.
Choose Azure DevOps Services when you want the following results:
Quick set up
Maintenance-free operations
Easy collaboration across domains
Elastic scale
Rock-solid security
You’ll also have access to cloud load testing, cloud build servers, and application insights.
Azure DevOps Repo for your Templates
From here you can make your Infrastructure as Code (IaC) Pipelines together with your Cloud Administrator Team 😉
When you have your Azure DevOps Private Repository in place and you like to work with Visual Studio for example, you can connect to your Repo and Check-in your NSG ARM Script but Deploy with Visual Studio to your Azure Virtual Datacenter.
So you see there are enough ways to deploy ARM Templates and this is not all, because you can also use Azure Cloudshell for example or other CLI command-line interfaces. But now we want to set the NSG Baseline for our Azure Subscription. A good start is to see the possibilities in the JSON scripting for Network Security Groups. Here you find the settings and explanation of Azure Components.
By Default is Internet available in a NSG ! So here you see that Internet is not allowed only the AzureCloud West Europe resources because some Azure SDK Component work via ” Public internet” ( Microsoft IP-Addresses). (RDP protocol is marked and not set in this example for Security reasons)
Internet by Default Rules, so you must set your security Rules !
Conclusion :
You really have to implement Azure Security by Design, make your Base-line with ARM Templates in a Private Repo for your Azure Network Security Groups with the Correct RBAC Configuration for your Cloud Administrator Team. Don’t make them manually and do settings manually when you have a lot of NSG’s ! Versions of your ARM templates are documented in your Repository 😉
Test Always first in a Dev-Test Azure Subscription or in Azure DevOps with a Test plan before you implement in Production.
