Effective patterns for putting your data to work on Azure
Various interactive options are available to inspect messages in Azure Event Hubs or IoT Hubs, such as Azure Portal, Service Bus Explorer (Windows only) or Azure IoT Explorer. However, for developer convenience or scripting automation, you may prefer using a CLI tool to stream the messages directly into a console or file. The Kafka Console […]
Azure Pipelines offers a variety of extensions for integrating Terraform: An official one from Microsoft which has a number of limitations and has not been receiving any updates for years. A very popular one developed by my colleague Charles Zipp, which offers great functionality, but not all enterprises wish to install community extensions for Azure […]
You can use Terraform as a single source of configuration for multiple pipelines. This enables you to centralize configuration across your project, such as your naming strategy for resources. When running terraform apply, the Terraform state (usually a blob in Azure Storage) contains the values of your defined Terraform outputs. In your output.tf: The Azure […]
See Part 1, Using Azure AD With The Azure Databricks API, for a background on the Azure AD authentication mechanism for Databricks. Here we show how to bootstrap the provisioning of an Azure Databricks workspace and generate a PAT Token that can be used by downstream applications. Create a script generate-pat-token.sh with the following content. […]
A simple way to unit test notebooks is to write the logic in a notebook that accepts parameterized inputs, and a separate test notebook that contains assertions. The sample project https://github.com/algattik/databricks-unit-tests/ contains two demonstration notebooks: The normalize_orders notebook processes a list of Orders and a list of OrderDetails into a joined list, taking into account […]
(updated 2019-11-18 with streaming-at-scale repository link) Apache Flink is a popular engine for distributed stream processing. In contrast to Spark Structured Streaming which processes streams as microbatches, Flink is a pure streaming engine where messages are processed one at a time. Running Flink in a modern cloud deployment on Azure poses some challenges. Flink can […]
The easiest way to train an Object Detection model is to use the Azure Custom Vision cognitive service. That said, the Custom Vision service is optimized to quickly recognize major differences between images, which means it can be trained with small datasets, but is not optimized for detecting subtle differences in images (for example, detecting […]
Using Azure DevOps pipelines, we can easily spin test environments to run various sorts of integration tests on PaaS resources. Azure DevOps allows powerful scripting and orchestration using familiar CLI commands, and is very useful to automatically spin entire environments using Infrastructure as Code without manual intervention. Sample project In this example, we looked at […]
Building simple deployment pipelines to synchronize Databricks notebooks across environments is easy, and such a pipeline could fit the needs of small teams working on simple projects. Yet, a more sophisticated application includes other types of resources that need to be provisioned in concert and securely connected, such as Data Factory pipeline, storage accounts and […]
Until now, embedding Power BI reports or dashboards into a web application or automating processes with the Power BI API required a master account. A master account is an actual Power BI account with a username and password that the embedding app uses to connect to the Power BI API. The master account that is […]
