Using PowerShell and the VM Custom Script Extension to download and execute scripts on existing Azure VMs


The complexities around Azure Active Directory can be difficult to understand. This post runs through some of the key concepts – AAD apps, service principles, managed identities, and walks through an example of how to set some of this up!


When he joined endjin, Technical Fellow Ian sat down with founder Howard for a Q&A session. This was originally published on LinkedIn in 5 parts, but is republished here, in full. Ian talks about his path into computing, some highlights of his career, the evolution of the .NET ecosystem, AI, and the software engineering life.


We’re currently building a Data Governance Platform product that enables UK Financial Services organisations to discover and manage the life-cycle, usage, risk and compliance requirements of data assets across the organisation. Much of the core functionality is delivered using Cosmos DB’s Gremlin API to model data lineage and other relationships best represented by a graph […]


Overflowing with dataflow part 1: An overview

by Carmel Eve

This is the first blog in a series about dataflow. The series focuses on TPL dataflow, but this post gives an overview of dataflow as a whole.

The crucial thing to understand when using dataflow is that the data is in control. In most conventional programming languages, the programmer determines how and when the code will run. In dataflow, it is the data that drives how the program executes. The movement of data controls the flow of the program.


I’m very excited that Ian Griffiths has joined endjin as a “Technical Fellow”. This is a new career pathway branch we created especially for Ian, as he didn’t really fit into any of our existing roles; his skills and expertise exemplify a pathway that many software engineers desire, but few have the opportunity to achieve […]


OpenAPI Document Converters for Visual Studio 2017

by Howard van Rooijen

In my previous post I documented a technical spike I carried out to see how I could take the OpenAPI.NET SDK and create a Custom Tool in Visual Studio, in particular a Single-File Generator, that could be used to improve the Azure Functions v1 local development experience. Since then the OpenAPI.NET SDK reached v1.0 and while I was […]


Using Python inside SQL Server

by Ed Freeman

Do you have a bunch of data in SQL Server that you’re using ODBC/JDBC to pull data to work with in Python? Using SQL Server’s Python integration, you can connect to a SQL Server instance within your preferred IDE and perform the computations on the SQL Server Machine. No more clunky data transferring. Operationalizing a Python model/script is as easy as calling a stored procedure. Any application that can speak to SQL Server can invoke the Python code and retrieve the results. Easy! This blog will provide a few, simple examples which make use of this capability to carry out some simple Python commands, so you can get up and running as quickly as possible.


Learn what types of things an apprentice gets up to at endjin a few months after joining. You could be learning about Neural Networks: algorithms which mimic the way biological systems process information. You could be attending Microsoft’s Future Decoded conference, learning about Bots, CosmosDB, IoT and much more. Hopefully, you wouldn’t be in hospital after a ruptured appendix!


One of the great benefits of Azure (and the Cloud in general) is the simplicity with which you can create and scale resources. The downside to this is that you can easily lose track what you’ve got deployed, or accidentally create expensive items and leave them running. We wanted a way to track our spending […]


Digital Transformation is the buzzword of the moment; organisations are trying to reconfigure themselves to operate in the digital age. One of the key enablement strategies involves putting APIs at the heart of the organisation to centralise access to data, logic and value, while removing those traditional barriers that prevent collaboration between organisational silos. APIs […]


How to plan your cloud transformation journey

by Howard van Rooijen

This week I received an email from someone who asked how they could use our free Thought Leadership content to help their organisation move to the cloud. I realised that although we’ve released a lot of content, we’d never talked publicly about the rationale behind them and how they are all interconnected. Our Thought Leadership […]


Azure Tech Selector – 2017 Edition

by Matthew Adams

A couple of years ago we put together the Azure Tech Selector – a handy poster which walks you through the technology choices you can make for common cloud workloads. Now, two years later, the number of services provided in the Azure ecosystem has multiplied (and the types of workload have become more sophisticated). Revisiting […]


Best of the Recorded Azure Sessions at BUILD 2017

by Howard van Rooijen

For this week’s edition of our Azure Weekly Newsletter, I reviewed all the Azure related sessions from BUILD that are now available on Channel 9 and categorised them into the standard grouping we use for Azure Weekly. If you’re not a subscriber, I’ve included the list below: Compute Container apps on Azure App Service are […]


This post explains how to create a PowerBI report which sources data from two separate Azure SQL Databases. PowerBI offers two data access mechanisms; Import and DirectQuery. DirectQuery provides a range of benefits, the chief of which is that data is automatically refreshed. DirectQuery doesn’t import any data into PowerBI, instead it queries the data […]


Benchmarking the Cloud against on-premise data centres

by Howard van Rooijen

Guest Blogger – Barry Smart (Former CTO & Partner, Hymans Robertson) Barry was the CTO at Hymans Robertson, the largest independent firm of consultants and actuaries in the UK. He is responsible for leading the firm’s technology strategy. The firm is turning increasingly to technology to enhance and extend the services it provides to clients. […]


One very useful but little used pattern when working with Resource Manager templates, is the ability to use parameters to optionally deploy resources, constrain certain resource configurations based on other user defined parameters, or to toggle parameters based on other values. To give a couple of concrete examples, imagine we have a highly reusable template […]


Read about how we set up automated backups of our office security camera footage and used Power Automate to alert us if anything went wrong


Choosing the right cloud platform provider can be a daunting task. Take the big three, AWS, Azure, and Google Cloud Platform; each offer a huge number of products and services, but understanding how they enable your specific needs is not easy. Since most organisations plan to migrate existing applications it is important to understand how […]


How to use Power BI Embedded with AspNetCore

by Matthew Adams

If you are looking to build an AspNetCore website, and take advantage of Power BI embedded, you’ve probably found that there isn’t any SDK support for basic report rendering (yet). While the underlying PowerBI.Core and PowerBI.Api assemblies work just fine, there is no equivalent to PowerBI.MVC, and PowerBI.Javascript fails to install correctly in the new […]
