INDEXES Indexes are like indexes at the end of your book. They are used to access data faster. For example, select start from tab one where call one equals to one will scan the entire table to bring the rows where call one equals to one. Instead, if we have an index on that column, it will use the index which stores the value in an order and corresponding pointers to the table to find out the data faster. This way, a full table scan is not needed. Of course,…

Monitoring Azure With any solution, it’s important to be able to monitor the various components you use, not only for troubleshooting problems, but also to be alerted of performance or security issues. Many companies must also be able to demonstrate comprehensive auditing capabilities for compliance and security reasons. Azure provides a range of monitoring tools to achieve these tasks and more. Originally, many of these monitoring capabilities were distinctly separate. However, Microsoft are slowly bringing them all together into a single to cohesive suite. Generally speaking, monitoring uses two main…

Azure Logic Apps Introduction In the next few lectures, we’re going to look at logic apps. Logic apps are a server less offering by Azure. Logic apps help you build solutions that integrate apps, data, systems and services across enterprises or organizations by automating tasks and business processes as workflows. Logic Apps is a cloud service in Azure that simplifies how we design and create these scalable solution, whether in the cloud, on premises, or both. Some of the benefits of Azure logic apps are you can get started very…

Azure Functions via Portal Walkthrough Let’s go ahead and create a function. There’s actually two ways we can create functions. The simplest way is we can actually create them and even code them through the portal itself. And the second way is we can use an editor such as Visual Studio. We’ll go off the first option first and we’ll create a simple function go to to create a resource and we often have it as a quick start. Here a function app. But again, if it doesn’t appear, you…

Kubernetes Introduction We’re now going to look at a service called Kubernetes. To understand what Kubernetes actually is, we need to take a small step back. So in the previous lectures, we’ve been looking at Containerization and specifically containerization with Docker. So using DACA, we now have container images that are registered in a container register. In our case, it was the Azure Container Registry and from there we can use those images to spin up instances or running containers. So two questions may speak to mind. The first is…

Containers Setup Walkthrough In order to follow the next lecture, you’re going to need docker installed on your computer. If you haven’t got docker already, it’s quite easy to get go to Docker. com, go to products and we want the Docker desktop, go ahead and download it for your environment. So once docker is installed, we can go and run it here. Created a shortcut on my taskbar and because of the kind of application it says, it actually runs in here in our task icons here. And we…

Service Bus Walkthrough Part 2 Now we’ve looked at queues. Let’s go ahead and look at Topics and Subscriptions so that we can see the difference. Again, we can have a click Q from up here, or if we scroll down the sides left, we can go to the Topics view under Entities and then click Add to create a new topic. Give the topic a name name. We’ll call this my topic and again we can set certain parameters such as the topic size, message, time to live, duplicate…

Service Bus Introduction Azure Service Bus is a multitenant cloud messaging service that sends information between applications and services. The information is stored in a messaging queue. The Asynchronous operations give you a flexible brokered messaging along with structured processing and a published subscribe capabilities. Queues offer first in, first out messaged delivery systems. That is, receivers typically receive and process messages in the order in which they were actually added to the queue, and only one message consumer receives and processes each message. The Service Bus implementation takes care…

Web Apps – Git Deployment Walkthrough Before we finish with web apps, I want to go through one more item and that is deployment. When we spun a Power web app, originally we deploy to it directly from Visual Studio. However, especially when working in teams, this is not how you would often deploy web applications. More often than not, you would use a process known as dev. DevOps. With DevOps, what happens is a particular product is broken down into a set of product backlog items, which in turn…

Web Apps – Authorisation Walkthrough Next, let’s take a look at authentication and authorization. Many websites need you to be able to sign in in order to authenticate you. And this can be achieved in many different ways from third party identity providers, Azure Active Directory, Active Directory, or even just standard database back to username and passwords. The majority of these require some amount of programming effort on the developer’s behalf in order to integrate them, especially token based providers such as Facebook, Google and even Microsoft. Microsoft Azure…
