Implement CI/CD with Azure DevOps

-
Gambar
  Introduction      Imagine you are part of a team of data engineers who are collaborating on one or more notebooks within a development environment, using Azure Databricks. When you are ready to deploy your changes to production, you must coordinate with an operations team to copy the notebooks over to a production Azure Databricks workspace since company policy dictates that you and your team are not allowed to manually copy the changed files over. This process causes bottlenecks and extra work. Leadership has asked you to find an automated process that incorporates version control, automated testing capabilities, and controls for deployment approvals if needed. Automated testing and deployment is a common practice in software development. However, those same principles also apply to data engineering and data science. Data engineers and data scientists need to collaborate on parts of the system and be able to deploy to production without constantly relying on opera...

  Identify the product options      IoT enables devices to gather and then relay information for data analysis. Smart devices are equipped with sensors that collect data. A few common sensors that measure attributes of the physical world include: Environmental sensors that capture temperature and humidity levels. Barcode, QR code, or optical character recognition (OCR) scanners. Geo-location and proximity sensors. Light, color, and infrared sensors. Sound and ultrasonic sensors. Motion and touch sensors. Accelerometer and tilt sensors. Smoke, gas, and alcohol sensors. Error sensors to detect when there's a problem with the device. Mechanical sensors that detect anomalies or deformations. Flow, level, and pressure sensors for measuring gasses and liquids.      By using Azure IoT services, devices that are equipped with these kinds of sensors and that can connect to the internet could send their sensor readings to a specific endpoint in Azure via a messa...

Gambar
  What is ASP.NET Core SignalR?      All internet-connected applications are composed of servers and clients. Clients rely on servers for data, and their primary mechanism for receiving data is through making Hypertext Transfer Protocol (HTTP) requests. Some client applications require data that changes frequently.      ASP.NET Core SignalR provides an API for creating server-to-client remote procedure calls (RPCs). RPCs invoke functions on clients from the server-side .NET Core code. There are several supported platforms, each with its own client SDK. Because of this, the programming language being invoked by RPC calls varies.      It's helpful to familiarize yourself with the common terminology that's associated with SignalR. In this unit, you'll learn what SignalR components are required in a server application versus those in client applications. Additionally, you'll gain an understanding of the various duplex communication mechanism...

       A virtual private network (VPN) provides a secure encrypted connection across another network. VPNs typically are deployed to connect two or more trusted private networks to one another over an untrusted network such as the internet. Traffic is encrypted while traveling over the untrusted network to prevent a third party from eavesdropping on the network communication.      You are responsible for networking at Adatum, a home maintenance, security, and automation company. Adatum has several multi-tier applications that run on Windows and Linux virtual machines. These virtual machines are in the process of being migrated from an on-premises datacenter to the Microsoft Azure cloud. These applications store sensitive customer information and the virtual machines that host them should never be exposed directly to the internet.      Adatum has a large number of remote workers who use laptop computers to interact with these applications...
