Configure Pod Identities or Create a Service Principal which we will use to access the storage account.

Before we get started, we require the following pre-requisites: Let's go through the process of setting up the proposed solution in a lab environment. Scheduling Private Test Runners with Kubernetes I lean towards a container-based approach as a container image is a neat way for sharing this functionality amongst teams and simplifying private test setup for development teams.

Azure Kubernetes Service, Kubernetes is another great candidate for running our tests and provides some useful primitives for scheduling simple jobs.

Azure Functions is a great serverless option and providers the Timer Trigger which can be used for scheduling.

Azure Container Instances + Azure Logic Apps, we can combine these two services to run a container which executes our tests on a schedule.

In Azure we have quite a few interesting options for executing our tests:

The source code for the solution I am proposing can be found here.

Leverage the App Insights SDK to Create and run custom availability tests.įor the remainder of this post, I am going to focus on providing a complete solution leveraging the concepts documented in Option 2.

Keep in mind that it still requires a public IP address and DNS needs to be publicly resolvable.

Azure Service Tags, it's possible to whitelist inbound traffic from the Application Insights Availability service by leveraging the " ApplicationInsightsAvailablity" Service Tag.

There are a couple of alternatives for these enterprises: Unfortunately, not all enterprises are able to leverage the functionality described above as network traffic generated by the Availability testing service originates from a pool of IP addresses assigned to the service from a Microsoft managed network. Another benefit is that these tests can also be configured to originate from one or more Azure Regions which are supported by the Availability testing service. One of the benefits of these built-in test types is that enterprises do not need to manage deployment of an agent or any special infrastructure to enable these scenarios.

Multi-step web test - We can record a http session and leverage this a webtest file for executing multiple steps during our testing.URL ping test - Simple Http Status check with options for configuring request timeout, expected status code, retries & parsing dependent resources.Out of the box the following two types of tests are currently supported by the service:

Telemetry and Metrics which are being ingested from Application Insights or other Azure Monitor agents running in your network.įor the remainder of this post I will focus on Application Insights Availability Testing, this is a great capability which allows you to monitor the availability of your applications. Keep all traffic inside the Microsoft Azure backbone network.Ī key point to note in this scenario is that private network traffic is mostly supported in an outbound direction from your virtual network in Azure to the relevant Azure Monitor service i.e.Securely connect your private on-premises network to Azure Monitor using ExpressRoute and Private Link.Prevent data exfiltration from your private networks by defining specific Azure Monitor resources that connect through your private endpoint.Ensure your monitoring data is only accessed through authorized private networks.Connect privately to Azure Monitor without opening up any public network access.

In Azure one of the ways that that a service does this is by adding support for Private Link, in general the Azure Monitor services already support this scenario via Azure Monitor Private Link Scopes.Īs per the official docs Azure Monitor Private Link support allows enterprises to do the following: When adopting any cloud service in a highly regulated enterprise there are some common requirements which start to appear, one such requirement is that the service support private connectivity. The Application Insights service provides several extremely useful capabilities for instrumenting & monitoring your application workloads. Azure Application Insights is a fundamental service for DevOps teams, the service is part of the overall Azure Monitor stack provided by Azure.
