Azure Resource Manager templates are great. Managing the resulting JSON files not so much. So Microsoft launched Azure Bicep. Read how it will help with maintaining your infrastructure as code.
Always wanted to run Python on Azure? We'll show you how with Azure Container Instances.
Microsoft has recently taken us on a word lingo with the launch of Azure Synapse Analytics. At Kohera, we've experienced some confusion in the market between Azure Synapse as a standalone product and Azure Synapse Analytics as a SaaS platform. We guess it's time to set things straight once and for all, or at least for a while.
A client asked if we could provide a simple form of monitoring on a part of a provided solution. For this particular source, our client asked us to send a simple email with record counts to a mailing list. No problem! Let's get to work
Sometimes, Databricks can be a bit sluggish. Caching with, for instance, the Delta Cache Accelerated Worker can help you speed it up. We'll explain how it does that.
While XML has been suitable as a SQL Server native datatype since SQL 2005, for one reason or the other it’s not often used - with only a very few working examples. This blog post is meant for T-SQL teams looking for a working XML example on SQL Server, including schema binding and XML indexes.
Kohera’s Modern Data platform does not come with a canned data model by default. This makes the framework extremely flexible to adapt to a variety of project workflows, but it also means during the Analysis phase we will need to think about how to structure the data before continuing. A blogpost.
Some of our customers want us to import their data from a standard on-premises or cloud-based (Azure) SQL-database, others want us to import their data from a REST API. If ever, you’ll have to import data from a REST API, you’ll surely encounter some obstacles.
Azure SQL Database serverless is a new compute tier made for single databases. This new model automatically scales the compute based on the actual workload per second. This means that you only have to pay for the compute resources (memory & vCores) you use. But there's more...
Tired of logging on to Azure Data Factory every day and checking the status of your pipeline(s)? In this blog, Data Wizard Wout Cardoen shows you how to develop an automatic email that alerts you when a pipeline fails.
Azure Databricks is a cloud native (Big) Data analytics service, offered as a managed PaaS environment. It’s designed to hide the underlying distributed systems and networking complexity as much as possible from the end user, so you can focus on developing rather than having to stress over infrastructure management.
When I started to jump from DBA to Data Architect, I thought that these roles would diverge further and further until they became two separate roles and functions. The current evolution Microsoft launched proved me wrong though. Enter Azure Synapse Analytics.
Stefanie was planning to update her knowledge on Microsoft Azure. After a good night rest, she was ready for this new adventure. She opened up her laptop, turned on the power and immediately stopped and stood up. First things first. Black gold. Now she was ready to learn about Managed Instance.
Data Lakes are the foundations of the new data platform, enabling companies to represent their data in an uniform and consumable way. In this document, we’ll describe how to setup a Data Lake in such a way that it will become the efficient Data Lake that users are looking for.
Oh, this is cheesy, can’t believe we could ever dare to mention Mariah Carey in our blogpost series. Well, the holiday season is starting, so there is no escape at all 😊. By the way, what I meant with the title was: All I need for Christmas is you… Azure Data Flow.
Automating a Data Factory pipeline using a runbook seemed like an easy last step in a Azure DWH setup I developed lately. The part in my script responsible to start and stop the DWH ran without problems, but then ...
I made a very useful ELT program in python and wanted it do run inside a Databricks cluster. Databricks on Azure fully supports python 3, so I thought I was up for a walk in the park. Trying to import the database connection classes, already gave a small hint of the troubles ahead...
Is SSRS on Azure happening? Well as always in Azure it depends… If you mean that ‘SQL Service Reporting Services’ is going to be provided on Azure, the answer is NO as SSRS is a product name as well as a part of SQL Server. But...
An Azure data warehouse is a real powerhouse. Personally, I consider it to be one of the most performant components that can be used and build into the Lambda architecture. Ludicrous power comes with a drawback of course and that drawback is potential inefficiency.
In previous blogposts we have been creating the Linked Services in Azure and CTAS’ing files from Azure Data Lake into tables on Azure DWH. I finished my previous post by advising you to use Azure Data Factory V2 (ADF) as an orchestration tool for your ELT load. This is exactly what we’ll be doing in this post.
Enter Polybase External Tables. A technology introduced in SQL Server Parallel Datawarehouse (PDW) around 2013 and became more generally available since SQL 2016, allowing you to read flat files as easy as if they were database tables.
How to best describe Azure Data Factory (ADF) V2? A friend of mine described it as the ETL of the skies. And since I based almost my entire career on ETL tools, this sounded like music to my ears. After running a nice project in ADF I can now look back on this statement, and conclude there is some truth behind it.
For the moment, SSRS (SQL server reporting services) is currently not an Azure component. Will it be available in the near future…? I don’t know. SSRS- functionalities become available in other dashboards and reporting tools like Power BI. Today, you’ll need to work with an on-premise installed SSRS server or you'll have to setup one in an Azure VM.
One little step in a migration track from on-premise to Azure is related to binary files like images, pdf and others. These files are often stored on many different places. When these files are stored in SQL, you probably have already created a variety of SQL procedures. But you can also use Azure blob-storage.
Attractive reports are not only showing the hard material statistics and numbers. Visualization of your data leads more and more to graphical decision making. One particular part of your reports are images for logo’s, product images etc. When moving to the cloud, where do we need to store and find our data and images?
I truly believe in the azure environment. The possibilities are huge and growing every day. Do we all need to migrate to the cloud ‘sito-presto’…yes, I think so. Why I’m so sure about this, is easy to explain. The most important reasons for me are: cost-efficient architecture possibilities and lower maintenance due to very stable architecture solutions.
With Analysis Services, you can mashup and combine data from multiple data sources, define metrics, and secure your data in a single, trusted semantic data model. The data model provides an easier and faster way for your users to browse massive amounts of data with client applications.
Moving Azure SQL Datawarehouse to the cloud made it available for the majority of all companies, enabling them to use this workhorse as a powerful engine to drive their analytical needs. Now the "Gen 2" is five times faster than the already blazing fast Gen1.
Are you familiar with the lambda architecture? It actually splits data flows into two components, receiving data centrally and doing as little as possible processing before copying and splitting the data stream into two streams, namely the real time and batch layers.
As you might have noticed, data science is not just a buzz word anymore. It has become serious business! Why?
Cloud computing is no longer just a buzzword, it is here to stay. Companies should prepare by looking into cloud technology and getting their cloud strategy sorted out. If you look at cloud computing in its most basic form, you could simply call it store stuff on the internet. Although this is partially true, the cloud has much more to offer.
