With Linux, the primary method for obtaining debugging information of a serious error or fault is via the kdump mechanism. Kdump captures a wealth of kernel and machine state and writes it to a file for post-mortem debugging. But if kdump writes to a file on a remote server, and networking is down, then kdump cannot work. In this context, networking includes the guest’s network driver and stack, the host’s network driver(s), and the network hardware both on the host […]

I recently worked with a group including Vishwas Lele and Jesse FitzGibbon to design and execute an accelerated learning series on Robotic Process Automation (RPA) with Microsoft Power Automate, kindly dubbed the “AIS RPA Crash Course.” We set out to engage a team of roughly 20 AIS employees with a diverse set of skills and experience levels with the goal of providing them with the practical experience to contribute to enterprise-level automation projects with AIS customers. It proved to be […]

Defining your cloud computing infrastructure as code (IAC) is becoming an industry standard for enterprise IT teams to scale effectively as their development teams and applications grow. Terraform, by Hashicorp, is an infrastructure as code tool that lets you define both cloud and on-prem resources using human-readable configuration files that you can version, reuse, and share across your various projects and development teams. This post will focus on several methods and patterns to make the most out of your terraform […]

There are times when you must correlate different log sources within a centralized Azure Log Analytics Workspace to have a single management point for leveraging the robust suite of tooling available within Azure that provides visualizations (Dashboards / Workbooks) and action and mitigation capabilities (Alerts / Automation). If you have resources spanning multiple tenants, Azure lighthouse is used to delegate access to these resources to collect these logs. However, Azure lighthouse has its limitations. One that we recently encountered with […]

Recently, I was involved in a project where we had requirements. A report needed to be built based on data from several sources, including Azure Cosmos DB and Azure SQL. This report was required to be stored in Azure, and data was subject to a retention policy where it would be unable to be deleted. For this use case, we decided to use Azure Data Factory to read the data, transform the data, and load the data into a CSV […]

Automating the build and deployment of an Angular application in the Azure DevOps (AzDO) ecosystem is as easy as any other code hosting service. AzDO has added task types to help deploy directly to Azure subscriptions. In this post, we will look at creating a build pipeline with caching, discuss deploying to Azure App Service, and pushing a container to the Azure Container Registry for use in AKS. Building the Pipeline AzDO does have a GUI to help set up […]

As part of one of my projects, I was asked to research methods of transferring large amounts of data (> 1 Terabyte) between client-owned S3 buckets. Several suitable techniques are available. They include: Running parallel uploads using the AWS command-line interface (CLI) Using an AWS SDK (Source Development Kit) Using cross-region or same-region replication Using S3 batch operations Using S3DistCp with Amazon EMR Using AWS DataSync Some of these methods, such as copying files and directories using the AWS CLI […]

We know most software applications, desktop, mobile, or web, require a database at the backend to store data. When we look at current software applications, the complexity is very high, and they have a high frequency of data transactions. So, we need testing of the data stored and retrieved from the database to make sure it has proper data integrity. Any database operation performed by the application is always one of the four, Create, Retrieve, Update and Delete. We were […]

While recently working on moving an FTP server (using Passive FTP) from on-premises to Azure, I needed to expose the FTP server to the internet via an Azure External Load Balancer. A few things were not well documented. I thought it would be good to put together a step-by-step guide on setting up the load balancer, configuring the FTP server on the backend, and setting the Network Security Group rules associated with the FTP server. In this example, the FTP […]

In a previous article, we explored using the CSI Secrets Store Driver and Azure Provider to mount an HTTPS certificate stored in Azure Key Vault on pods deployed to Azure Kubernetes Service (AKS). This was done using Linux containers and an ASP.NET Core application. But what about .NET Framework applications on Windows containers? Let’s see if we can take the same approach. About Windows Containers Containers initially grew out of the Linux world based on its natural support for container […]
