Using the Copy Wizard for the Azure Data Factory

0
2
It used to be a considerable task to creating a feed for a data warehouse. Now, it just takes a few minutes to work through a series of screen s to create a pipeline that, in this example, creates a pipeline that brings data from a remote FTP server, decompresses the data and imports the data in a structured format, ready for data analysis. The Copy Wizard for the Azure Data Factory is a great time-saver, as Feodor Georgiev explains.… Read more

Azure Resource Manager (ARM) Templates

If you need a way of deploying infrastructure-as-code to Azure, then Azure Resource Manager (ARM) Templates are the obvious way of doing it simply and repeatedly. They define the objects you want, their types, names and properties in a JSON file which can be understood by the ARM API. Ed Elliott takes the mystery out of a simple means of specifying your Azure environment, whether it is a VM with blockchain software, SQL Server or a Web App on Linux with PostgreSQL … Read more

Azure Data Lake Store is an extendable store of Cloud data in Azure. You can move data to and from Azure Data Lake Store via Azure data Factory or Azure SQL Database and connect to a variety of data sources. You can script upload files from on-premise or local servers to Azure Data Lake Store using the Azure Data Lake Store .NET SDK. Ambily KK shows how easy it is to get started by setting up a script or App to move data to Azure Data Lake Store.… Read more

Azure Data Factory provides a radical new cloud-based way of collecting and preparing data in preparation for its storage and analysis. How do you get started with it to explore the possibilities it provides? Feodor Georgiev shows the practicalities of how to go about the task of preparing a pipeline for use, from preparing the Azure environment to downloading a file from a FTP to a blob storage in the Azure environment… Read more

Pseudonymization and the Inference Attack

0
6
It is surprising that so much can be identified by deduction from data. You may assume that you can safely distribute partially masked data for reporting, development or testing when the original data contains personal information. Without this sort of information, much medical or scientific research would be vastly more difficult. However, the more useful the data is, the easier it is to mount an inference attack on it to identify personal information. Phil Factor explains.… Read more

Data in Motion and Data at Rest

Microsoft (StreamInsight), and Azure Stream Analytics represent a very different model for processing data. They are concerned with processing complex event streams of data (CEPs) from such things as sensors to deduce significant patterns and apply filters. Joe Celko discusses the background to an intriguing technology of complex event processing to establish the difference between data at rest, and data on the move.… Read more

Automating the Synchronization of RDS SQL Server Agent Jobs in a Multi-AZ Environment

0

Although Azure is the obvious Cloud service to host SQL Server, Amazon Relational Database Service (RDS) for SQL Server is a good choice when your organisation uses AWS. RDS deals with maintenance and monitoring, and supports the use of PowerShell to automate routine tasks. What if a script needs to be triggered by an unscheduled event? Even in this case, RDS can be configured to run scripts to react when something like a failover happens. Laerte Junior shows how easy it is to set up Lambda functions and some PowerShell scripts to automatically synchronise agent jobs after a failover.… Read more

Monitoring Azure Cloud and Hybrid Environments

Cloud-based services and applications must still be monitored just like the on-premise ones. You still need most of your data center activities that ensure that your planning, budgeting, security and service-level obligations are met wherever the data and services are actually hosted. There is much to be said for an integrated approach to providing a unified view of entire application workloads on-premise. hybrid and cloud using the same tools wherever possible. … Read more

Statistics in SQL: The Kruskal–Wallis Test

0
4
Before you report your conclusions about your data, have you checked whether your 'actionable' figures occurred by chance? The Kruskal-Wallis test is a safe way of determining whether samples come from the same population, because it is simple and doesn't rely on a normal distribution in the population. This allows you a measure of confidence that your results are 'significant'. Phil Factor explains how to do it.… Read more

Getting What You Need From Azure Storage Disks

0

If you need persistent data disks for Azure IaaS VMs that are supported on both Windows and Linux then you will be interested in Azure Storage Disks. These can increase the storage capacity of your VMs by up to a terabyte per disk, and they not only allow several availability options, but also offer a range of performance in terms of I/O throughput and latency. With right configuration, you can create as much of the right sort of storage as you need.… Read more

Personal Data, Privacy, and the GDPR

Now that there have been well-publicised examples of the awful consequences of data breaches and data misuse, there is increasing public pressure for legislation on privacy and personal data that has enough clout to prosecute serious offenders. In the vanguard has been the EU data protection regulation, soon to be succeeded by the GDPR. It defines IT practices for data that are likely to extend worldwide. William Brewer gives a rundown of what he sees as the implication for IT practice.… Read more

Working with Windows Containers and Docker: Into your Stride

So far, in this series, Nicolas has shown how to get simple container instances up and running with just some basic background information. Now we need to understand the differences between Linux containers, Windows Server containers and Hyper-V containers. We can then define, create and run multi-container Docker applications, and port existing Windows Container VMs to Docker.… Read more

Azure Load Balancers and SQL Server

Load balancing in Azure has more importance for the DBA, because it is essential for Windows Server Failover Clustering in Azure, whether it is for AlwaysOn Availaiblity Groups, Failover Clustered Instances, or any other highly-available solution. Azure load balancing works out the location of the availability group, and routes traffic there. The load balancer detects a failure, and routes traffic to the new primary replica. Joshua Feierman gives an overview of what is required.… Read more

How to Secure Your Azure Storage Infrastructure

Azure storage is an essential foundation for the more sophisticated services that Microsoft Azure provides. It is therefore important to understand how to make access to your data in Azure storage secure, to control access appropriately, to log activity and to get metrics on usage. Security in Azure can be easily managed and controlled via policies. There are a variety of ways to achieve the types of control over access that your applications need, as Christos Matskas explains.… Read more

Azure Networking for SQL Server DBAs

The network is important to any DBA because so much performance is dependent on I/O, because of the importance of security, and ensuring that everyone get the right access. DBAs generally need not become experts in Azure networks, but it helps to understand the concepts and language. If you are running a SQL Server Virtual Machine in Azure, then VNets, Subnets, Network Security Groups, VNet peering and VPN gateways are all worth knowing about in order to to keep SQL Servers running smoothly.… Read more

LogicApps are a managed service that provides the Lego blocks of Azure serverless architecture that you can use to create, develop and deploy cloud-based integrations and workflows. The developer merely strings together off-the-self, ready-made components with as little effort as possible. The aim is to go from development to production in a few simple, reproducible steps. Microsoft are investing strongly in this technology, introducing many new connectors in line with the demands of the integration requirements of enterprises.… Read more

Exploring Azure Storage for SQL Server DBAs – Part 2

Managed Disks have simplified way that Azure storage interacts with the users' virtual machines, thanks to the way that it eliminates the need to deal with the Storage Account. It is now easier to add new disks to a virtual machine, either in PowerShell or via the portal. The Storage Spaces feature in Windows Server can be used to aggregate disks together and obtain higher levels of performance. Joshua Feierman explains how to do it all.… Read more
