Storing and serving data is a pivotal step in the end-to-end lifecycle from sourcing data to consuming it. It is within the storage and serving layer where cleansed, transformed, and curated data is made available for consumption by the end users. Consumption can come in many different variations such as through Azure native BI tools including Power BI, Analysis Services, Power Platform, etc. Data within the Lakehouse can also be consumed by a variety of non-Azure BI tools such as Tableau, Informatica and more. A good Lakehouse serving layer offer flexibility for consuming the data from a variety of BI tools. In this section, our efforts will focus on understanding the capabilities of some of these Lakehouse consumption options within Azure.

Analysis Services

Azure Analysis Services is a fully managed platform as a service that provides enterprise-grade data models in the cloud. With Analysis Services, users can create secured KPIs, data models, metrics and more from multiple data sources with a tabular semantic data model. Analysis Services integrates well with a variety of Azure services and can connect to Synapse Analytics Dedicated pools. When comparing Analysis Services with Power BI Premium (PBI), Analysis Services (AAS) may offer better scale out capabilities, metadata translations, object level security, and perspective feature set, however in the modern Lakehouse organizations and users are strongly considering and choosing Power BI Premium over AAS due to its vast features including paginated reports, data flows, AI workloads, pay per user models, and much more. The table below lists many of these comparisons between PBI and AAS.

Power BI

Power BI (PBI) is an Azure native reporting technology which provides interactive visualizations, business intelligence capabilities which empower users to create their own visually appealing, accurate, and highly performant reports and dashboards. With Power BI, users can directly query the Lakehouse parquet files using the OPENROWSET function within a SQL query after specifying a SQL on-demand endpoint in the connection credentials. Within Synapse Analytics workspace, you can create a PBI linked service and used that within the various services of the Synapse Analytics unified analytics platform. Power BI also supports connectivity to a variety of other Lakehouse tools including Databricks, Snowflake, REST APIs and many more. From a cost optimization perspective, parquet will perform optimally due to its columnar storage format benefits, therefore the view on parquet files in Synapse Serverless SQL pools will result in low-cost compute resources. For a high number of queries across extremely large datasets, Dedicated SQL Pools may be the better storage choice to prevent from high costs incurring per query. Materialized views with External tables on Dedicated SQL pools may help with these high query volumes against the large datasets. When selecting a PBI service option, there are a few options to choose from which includes Premium versus Pro. Each option comes with its own capabilities and price points.

Power Apps

Power Apps is a suite of apps, services, connectors and data platform that provides a rapid application development environment to build custom apps for your business needs. There are two styles of these apps: canvas apps and model driven apps. Canvas apps provide you with a blank canvas onto which you can drag and drop components in any formation to design a user interface. Model driven apps are based on underlying data stored in Common Data Service (CDS), which is a secure, cloud-based storage space that organizations can use to store business application data. Canvas apps are ideal for building task-based or role-based applications. Model-driven apps, on the other hand, are better for creating end-to-end solutions. Within the Lakehouse, Power Apps fits within the consumption layer since users are able build custom apps to interact with data in the storage and serving layer using GUI based BI tools to interact with the data through read and write back operations.

Advanced Analytics

As data makes its way into the storage, serving, and consumption layers of the Lakehouse, a subset of your data consumers including from Business Stakeholders, Data Scientists, and others may be interested in the data from the perspective of performing advanced analytics on the Lakehouse datasets. These various stakeholders and data consumers would be interested in understanding how the capabilities that the Lakehouse provides as it relates to Cognitive Services and Machine Learning. With the benefit of having data stored in the Lakehouse which supports a variety of file formats such as images, parquet, JSON, Avro, xml, REST APIs, and more Azure cognitive and machine learning services can seamlessly connect to these various Lakehouse datasets through their Azure native tools and technologies.

Cognitive Services

Cognitive Services brings AI to developers through APIs and offers a variety of services to provide the ability for AI to see, hear, speak, search, understand and accelerate decision-making into apps. Developers of all skill levels and those that do not have an expertise in Machine Learning can easily add AI capabilities to their apps. The current available Azure Cognitive services include the following. Each of these services has the capability of connecting to Lakehouse datasets store and served in Azure Storage (ADLSg2 and BLOB):

  • Anomaly Detector: Identify potential problems early on.

Machine Learning

Azure Machine Learning is a service that delivers a complete data science platform. It supports both code-first and low-code experiences. Azure Machine Learning studio is a web portal in Azure Machine Learning that contains low-code and no-code options for project authoring and asset management and can connect to a variety of Lakehouse services including ADLS gen2, Azure SQL Database and more. Azure Machine Learning also integrates well with other Databricks, Data Factory, and Kubernetes services for model deployment. The three main machine learning techniques include the following:

  • Supervised learning: Algorithms make predictions based on a set of labeled examples that you provide. This technique is useful when you know what the outcome should look like.
  • Unsupervised learning: Algorithms label the datasets for you by organizing the data or describing its structure. This technique is useful when you don’t know what the outcome should look like.
  • Reinforcement learning: Algorithms learn from outcomes and decide which action to take next. After each action, the algorithm receives feedback that helps it determine whether the choice it made was correct, neutral, or incorrect. It’s a good technique to use for automated systems that have to make a lot of small decisions without human guidance.

Continuous Integration, Deployment, and Governance

Once you’ve fully built out your ingestion, processing, serving, storage, and consumption layers of your Lakehouse Platform, there are various options for continuously integrating and deploying automated code to multiple environments along with applying robust data governance policies and practices on data. This section will cover data CI / CD and governance (Purview) within the Azure Data Lakehouse Platform.


A CI/CD pipeline is used to automate the process of continuous integration and continuous deployment. The pipeline facilitates the software delivery process via stages like Build, Test, Merge, and Deploy. Azure DevOps Server is a Microsoft product that provides version control, reporting, requirements management, project management, automated builds, testing and release management capabilities. It covers the entire application lifecycle, and enables DevOps capabilities such as CI/CD within the Lakehouse. This section will cover the various CI /CD pipelines and process including SQL Database, Data Factory and MLOps deployments that can be built within the Lakehouse.

There are a few methods of deploying Azure Data Factory environments with Azure DevOps CI/CD. Source control repository options can range from GitHub to DevOps Git and implementation architectures can range from utilizing adf_publish branches to using working and master branches instead. Azure DevOps Build and Release pipelines can used for CI/CD, and custom PowerShell scripts can be used for deploying the CI/CD Data Factory resources automatically within upper environments. The Figure below illustrates the CI / CD process for ADF.

CI / CD within Azure SQL Databases and Synapse Dedicated SQL Pools is also possible with AzureDevOps. The best way to work with change control to prepare for CI and CD for databases is to perform all development using Visual Studio. There are a few source-control options within Visual Studio. GitHub is one of these source control options and offers a number of benefits including advanced security options. Integrating multiple applications such as Visual Studio, GitHub, Azure DevOps and Azure SQL Databases for a seamless CICD process is a growing need for many enterprises that are on a journey to modernize their data and infrastructure platform. The architectural flow diagram shown in the Figure below, illustrates how to deploy local SQL DDL and DML scripts from Visual Studio to an Azure SQL Database through a GitHub repository which is then picked up with an Azure DevOps Build (CI) and Release (CD) pipeline that tests and deploys the changes to the upper environments.

The DevOps CI / CD paradigm is prevalent across a variety of Azure PaaS services. DevOps for Machine Learning, also known as MLOps, enables Data Science, IT and Business teams to increase the pace of model development and deployment through automated continuous integration and deployment best practices. Well-designed MLOps paradigms support monitoring, validation, and governance of machine learning models. Large globally distributed organizations are seeking methods of success for deploying MLOps Frameworks across their organizations for multiple Data Science teams. They are seeking to clearly understand Azure MLOps Frameworks and patterns of success as they champion MLOps across their organizations. The Figure below, containing a generic Azure MLOps framework architecture diagram, illustrates just how Azure Machine Learning, coupled with Azure DevOps makes the concept of the Azure MLOps Framework a reality.
