Unified monitoring view in Kubernetes : Linking infrastructure monitoring with application monitoring

Introduction

Typically you notice that there are two dimensions / viewpoints when it comes to monitoring. On one side there is a team that wants to view everything related to the “infrastructure”, like for instance the kubernetes cluster. On the other hand, there is the typical application performance monitoring that starts from the application side. Sadly enough, in a lot of cases, those two are separated islands… 😦

 

As you might know, on the Azure front you can do Application Performance Monitoring with Application Insights and there is like a really awesome integration with Azure Monitor (“Log Analytics”) from the container space (kubernetes). Though I see you thinking it… Two separate solutions. Though, what a lot of people forget, is that they are actually using “Log Analytics” under the hood. And… That you can query across workspaces in Log Analytics! Which means that you can join the two and have an aggregated view to span both worlds.

 

Let’s take a look!

For this test, I’ve created a k8s cluster which is linked to a separate log analytics work-space. Where next to it, there is an application (Azure Function) inside of a docker container that is linked to Application Insights.

Test driving the newly announced Visual Studio Online

Introduction

This week Ignite kicked off with a series of announcements (as always). One of those was “Visual Studio Online“…

 

In my eagerness I wanted to test drive it and check out what the developer experience would be, and if it could replace my development station in Azure.  So let’s delve into it shall we?

Improving the security & compatibility aspects of package management with native GitHub features

Introduction

Did you know almost every piece of software depends on OpenSource? Not sure… What libraries is your software using? Bingo! 😉

Now we all know that package management can be a true hell. Tracking everything and ensure you are up-to-date to achieve the needed security level is hard. Next to that, there is always the risk that your build will break to moving to a library version.

What if we could enhance that flow a bit? You guessed it… Today’s post will be around how we can leverage native GitHub features to help us in this area!

 

Let’s hit the slopes!

For this walk-through, we’ll use the following ;

  • an existing code repository, where we’ve forked CoreUI’s VueJS repo
  • GitHub’s actions to run a workflow on every pull request
  • GitHub’s automated security feature that will send pull requests to us when it detects security issues

Want to test this one out or follow along? Browse to the following sample repository ; https://github.com/beluxappdev/CoreUI-VueJS-GitHubSecurityDemo

So let’s fork this sample repository!

Taking a look at Github Enterprise Server & Github Connect

Introduction

For today’s post we’re going to take a look at GitHub Connect … It’s the link between the On-Premises installation of GitHub Enterprise Server and the popular SaaS offering (as we all have come to love it) called GitHub. 😉

 

Installing GitHub Enterprise Server (on Azure)

So my journey for today started with registering for the GitHub Enterprise Trial, where I decided to install it on Azure… as my “On Premises” location.

Hardening your storage account with Private Link / Endpoint

Introduction

Earlier this week, a new capability called “Azure Private Link” (and also “Azure Private Endpoint”) went into public preview. As a nice copy & past from the documentation page ;

Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer/partner services over a Private Endpoint in your virtual network. Traffic between your virtual network and the service traverses over the Microsoft backbone network, eliminating exposure from the public Internet. You can also create your own Private Link Service in your virtual network (VNet) and deliver it privately to your customers. The setup and consumption experience using Azure Private Link is consistent across Azure PaaS, customer-owned, and shared partner services.

As always, we’ll take this one out for a spin! For this we’ll see if we can access a storage account privately (from a virtual machine) over the VNET.

Taking the user delegation SAS tokens for a spin

Introduction

A few days ago the preview for the “User delegation SAS token” has seen the light. In today’s post, we’ll take a first glance on this new capability! Though why should we care about this feature? You can now create SAS tokens based on the scoped permissions of an AAD user, instead of linked towards the storage account key. From a security perspective this is REALLY awesome, cause you can harden the scope of a possible even more.

Writing straight to the Azure Storage Access Tier you want (with AzCopy)

Introduction

With the “Set Blob Tier” operation you can set the Access Tier of the blob object of a storage account. Now at times you know a certain object will go to tier that’s not your default access tier. Or you want to write immediately to archive. The cool thing is that AzCopy can assist you in this!

 

AzCopy Flags

Take a look at the AzCopy flags… Here you’ll notice the “–block-blob-tier” flag. This is the one that’ll help you on writing directly to the access tier you want.

Quick Demo

I’ve created a storage account in mint condition, where the default access tier is set to “Hot”.
