Introduction and basics on Azure

1. Introduction to Azure

Hi and welcome back. Now in this chapter, I just want to go ahead and give an introduction to the Azure platform. So Azure is a cloud platform, which basically has more than 2200 products and cloud services. And let me go ahead and just give you a quick example of what the key benefit of using a cloud platform is. So let's say that a company wants to go ahead and host multiple Web applications. So this could be an ecommerce application where users can actually go ahead and buy the products from the company itself. So they want to go ahead and host these Web applications. Now, in order to go ahead and host these applications or even host the data, they would need to go ahead and buy physical infrastructure. So they would need to go ahead and buy a physical server. They would need to go ahead and buy storage. Then they would need to go ahead and create virtual machines on that physical server. This is one of the ways to go about doing this. And then they could go ahead and host their applications. Now, apart from all of this, there are so many other aspects that they have to look into. So for example, they have to also look into aspects such as networking. They have to look at aspects such as the power to the physical servers and storage. They have to look at aspects such as cooling. So there are a lot of things that they need to consider. So without Azure, if you're looking at setting up an application or a set of applications, a company would need to go ahead and first buy the hardware upfront. So for that, they would need to make an initial investment. Then there is a lot of set-up that is also required, and there could be ongoing maintenance costs. So all of this would need to be borne by the company itself. But when it comes to Azure, what's the best thing about this particular scenario? In Azure, what you can do is go ahead and directly create Azure Virtual Machines. With the help of the Azure Virtual Machine Service, you can then go out and host your applications on these virtual machines. The underlying infrastructure, everything—the physical servers, the storage, and the networking—are all managed by Azure themselves. It's managed by the Azure platform. That is what you mean by the cloud platform, wherein everything is already managed by Azure. And via the Internet, you can actually just go ahead and go onto Azure and start creating virtual machines. So one of the key benefits of this is that you don't need to go ahead and invest in any hardware upfront. The other best part is that you actually pay for how much you use. So when you're using virtual machines, just based on how much you use, you will only need to pay for that usage. And you can go ahead and terminate the resources whenever you don't require them. So if you don't need the virtual machine, you can go ahead and delete the virtual machine. This is different in comparison to when the company goes ahead and manages the entire set up. So let's say that the company does not need the virtual machines anymore. Then, whatever they have bought in terms of the physical infrastructure, everything is a waste. So Azure itself, or any cloud platform, for that fact, actually has a lot of advantages when it comes to hosting applications. So over here, I'm giving an example of my own site. So this is just a simple site that is based on WordPress. Now this entire site is actually based on Azure. It's actually hosted on the Zoe platform. Now, years ago, if I had to go ahead and host such a site, it would have been a headache. I would need to go ahead and buy servers. I would need to go ahead and set up the networking. I can't do this myself, especially if I'm an individual from a company perspective. Yeah, that's fine. But as an individual trying to go ahead and set all of this up, it's a headache. But it was very simple. It just took me a couple of hours to go ahead and have the basic site up and running. And I have my site running on the Azure platform with no issues. So Azure is a platform where you can actually go and make use of the products and services for developing your applications and even hosting your applications as well.

2. The Azure Free Account

Hi and welcome back. Now, for those students who are completely new to Azure, one of the ways you can actually go ahead and start exploring these services, which are present in Azure, is you can actually go ahead and create something known as an Azure free account. So in order to go ahead and start using Azure, you first have to go ahead and create an Asia account. To create an Azure account, you need to have a Microsoft account, which is very easy to create. So if you have a Gmail ID, you can go ahead and create a Microsoft account based on a Gmail ID, or if you have a GitHub account, you can go ahead and use either account to go ahead and create an Asia account. Even when creating an Asia-based account, this is required. You also need to have a credit card in place when you want to go ahead and create your free account. So the credit card is basically used for security purposes. In no way are you going to get charged until you actually go ahead and say, "Yes, I want to go ahead and start using these services, which are not free in Azure." So the credit card information that is asked for during the registration of an Azure Free account is used for security purposes. Now, when it comes to the Azure free accounts, if I go ahead and scroll down, there are some services that you get for free in addition to that in the Azure free account. So this can be done only once you get $200 worth of free credit to go ahead and explore the various Azure services. This $200 worth of credit is valid for 30 days. So either after 30 days or when your $200 worth of credit is over, then in order to continue using Azure, you have to go ahead and convert something known as your subscription. So this will be a free subscription that is attached to your free account. So we need to go ahead and convert that subscription into a "pay as you go" type of subscription. So that means you will start paying for the services that are not free in SEO based on how much you consume. So again, this depends on whether you want to proceed forward. So in order to do this, after the $200 worth of credit is over or after the 30 days have expired, you have to go ahead and convert that subscription. You can go ahead and go to this page and see all that you can actually do with your free account. So over here, you will see some of the products that are free. So please note that when it comes to these services, there are limitations. So even when it comes to, let's say, a Windows virtual machine, there is a particular size that is only free of cost. The other sizes must be purchased separately. But again, when you have the $200 worth of free credit, if you're using something that is not free, it will go against that $200 worth of credit. So that means you don't have to pay anything. So remember, this is only until the credit is there or until the duration of 30 days is still present. So over here, you can actually go ahead and look at all of the aspects when it comes to the Azure free account. Now, please note that there are other restrictions also in place when it comes to the Azure free account. So this is based on the feedback I get from students. So there are some services, let's say Azure Synapse Addicts, that you might not be able to use with the Azure free account. Also, you might not be able to use the services in the region of your choice. So there might be restrictions based on that as well. I just wanted to let you know that it's a good starting point for students who are new to Azure. I suggest you go out and create a free Azure account. Again, please note: you can only do this once. So for those who want to go ahead and start using Azure, I suggest they go ahead and create an Asia-free account.

3. Concepts in Azure

Hi and welcome back. Now in this chapter, I just want to go through some core aspects when it comes to Azure. Again, this is just for those students who are just completely new to Azure. So the first thing that you have to do is to go ahead and create something known as an Your account. Now, in your Azure account, you basically get something known as a subscription. So this is how you bill for a job. So based on how much you use and how much you have to pay, that would be based on your subscription. So remember, with your free account, you get a subscription wherein you get $200 worth of credit. But then after that, you need to start paying for services that are not free on Azure. Now, apart from that, there is another service known as your Active Directory that's part of Azure, and you get a free directory or a tenant that is part of your Azure account. So this is your identity store. So in Azure Active Directory, you can go ahead and create users that have access to resources that you define in Azure. Now, in Azure, there are so many products and services that you can use. So for example, you can go ahead and use the Azure Virtual Machine service to go ahead and create a virtual machine. Or you might go ahead and choose the Azure SQL Database service to create a SQL database. So all of these are known as resources. In Azure, when you go ahead and use a service to create a resource, it has to be created in a particular region or location. So Azure has many locations around the world where you can actually create your resources. So over here in the Microsoft documentation, I'm showing you the entire geography when it comes to the different data centres or the different locations across the world that lack your presence. So you can actually go ahead and create your resources in different regions. Also, in each region, you have to go ahead and see if the service is available. So for example, if I go on to explore products by region, and if I go ahead and just say, "Select all of the products over here," you can also go ahead and search for a particular product. So for example, if I'm looking at a service such as your data lake storage, I can see it is available in most of the locations. So in Canada central in Central US. in east US. But if we look at a feature known as Ultra Disc Storage, you can see that it's not present in the Canada East location. So ensure that whatever service you want to use is actually present in that particular region. Now, next, coming back to our particular diagram over here, Now, in addition to locations, every source also needs to be part of something known as a resource group, so the resource group is actually used to go ahead and provide a logical grouping of your resources. So a resource needs to be mapped onto a resource group. It also needs to be mapped on to a location, and it also needs to be mapped onto your subscription as well. So I said the subscription is a means of billing when it comes to Azure, right? So in this chapter, I just want to give an introduction to the core concepts when it comes to Azure.

4. Quick view of the Azure portal

Hi. Welcome back. Now, for those students who are not familiar with Azure, let me go ahead and just give a quick view of the Asia Portal. So the Azure Portal is one of the ways you can actually go ahead and interact with your usual services and your own resources. So on this page, I'm actually going to go ahead and click on the sign-in button since I already have your account in place. So I'm going to go ahead and use one of my existing Microsoft accounts. So it's basically a Gmail account that has also been dressed up as a Microsoft account as well. So I'll move on to the next one. So I'll go ahead and enter my password. So I'll say, "No, I don't stay signed in." just for security purposes. I can go ahead and click on the portal button over here, and I'll be directed onto the Azure Portal. So in the Azure Portal over here, I have my account, which I log in with. This is basically just the dashboard that you get. So if you want to go ahead and look at all of the resources that you have in Azure, you can go ahead and click on this button over here or on this icon over here. So, if you look at any particular resource, I already have a set of resources defined for the year. So this is what a virtual machine looks like. So this is a virtual machine resource. You can see that this resource is part of a resource group. So I said that this is an alogical grouping for your resources. It's also in a particular location, and it's also part of my subscription. So over here I have a subscription that is used for billing purposes. I've gone ahead and chosen the location of Central India because it is the closest to my location over here. So I get better response time when it comes to resources that I deploy. So if I want to go ahead and connect onto this virtual machine resource, it's much faster because the Central India location is closest to me. So try to choose a location that is closest to you if you want to go ahead and get better response time for the services that you are using. If you want to go ahead and create a new resource, you can go ahead and click on the Add button over here. When you click on the Add button, you are taken to something known as the Azure Marketplace. And over here, you get a list of the popular services that are used. And you can also go ahead and search for the services in your marketplace as well. Links to popular services are available on the left side. So your resource groups, your web apps, your app services, your SQL databases Whenever you do any operation in Azure, you also get a notification over here. So I can go back to all my resources. Now that I'm over here, if I just go on to my subscriptions, So currently I have multiple subscriptions in place when it comes to my billing. If I go on to any subscription, So over here we can see what my last bill amount was and what the current cost is. "Whatever you basically create in a Zoe," I said. So since I work with a lot of services, I create a lot of resources. I get billed every month based on how much I f services, I So in this chapter, I just want to give a quick overview of the Azure Portal.

5. Lab - An example of creating a resource in Azure

Hi and welcome back. Now in this chapter, I just want to give an example of the creation of a resource in Azure. Now that I have logged into my Azure account I already have a number of resources put in place. So I've moved on to my resources section here, all resources. And that's why I can see all the resources that I have in place. These resources are actually part of a resource group known as Domain. So over here, you can actually go ahead and organise your resources through the use of resource groups. These resources, which I have hosted over here, are actually in the Central India location. So these are nothing but virtual machines, actually. So if I go on to the virtual machines blade over here, these are virtual machines that I have defined in Azure. Currently, I don't have an immediate need for these virtual machines. That's why they are in the top de-allocated state. One of the best things about it is that you can create resources on demand whenever you need them. And when you don't want resources, you can actually go ahead and delete them. And also when it comes to resources like virtual machines, in order to go ahead and not get any sort of costs incurred, you can actually go ahead and stop these virtual machines. So these are some quick advantages that you actually have when it comes to working with Azure. So over here, I want to keep things very simple. I just want to go ahead and create something known as an Azure Storage account. With an Azure Storage account, you actually have the ability to use the different services that are available in the Azure Storage account to store your data. So in all resources, I can go ahead and click on adding a new resource. I could also go on to storage accounts and create a storage account from here. So in all resources, if I go ahead and click on Add, you could go ahead and search for the service that you want to base your resource on. So I can go out and search for storage account on this page when it comes to popular services; you might even see storage account over here. So you can actually go ahead and search for storage accounts. So it'll actually go on to something known as the Azure Marketplace. You can go ahead and choose this as your storage account, and we can go ahead and hit Create. Now when you're going out and creating resources in Azure, it will actually give you an alert when it comes to the Azure Portal. So, during this visit, you will be asked to provide various details about this storage account. Over here, all of the details are based on different categories. So when it comes to a storage account, you have to go out and give the basic information—information about networking, data protection, et cetera—for each type of resource that will actually change. This will actually vary. So if you are creating a virtual machine, for example, these options will be different. It all depends on the type of resource that you want to go ahead and create in Azure. So let's go ahead with the creation of the storage account. Now, the first thing that you have to specify when it comes to your storage account or any resource in Azure is your subscription. Now, you might be using the Azure free account, so you might have a free subscription in place, or you might have something known as a "pay as you go" subscription. So, over here, you pay for resources as you consume them. Now over here, I have a couple of subscriptions in place. Both of them are actually based on pay as you go" model. So even in this test environment, subscriptions are also based on the pay as you go model. The only difference is that I was given a name for this subscription. So you can actually go ahead and rename your subscriptions at any point in time. Whatever you consume in Azure or whatever you use in Azure will actually be billed against this subscription. Then you have to go ahead and associate with something known as a resource group. So a resource group is nothing but a logical grouping of resources. If you don't have a resource group in place, you can go ahead and click on "create new." Over here, I have a lot of resource groups already in place, but if you don't have any, you can go ahead and create a new resource group. You can then go ahead and give a name for the resource group and hit "Next." Okay, one of the main advantages of resource groups isif you want to go ahead and manage, let's say, the access control, or let's say you want to see the billing based on the resource group. So there are advantages to grouping your resources by resource group. So these two things are actually important for all the resources that you create in a job. It needs to be tagged on to a subscription for billing purposes, and it needs to be tagged on to a resource group. Next, we need to go ahead and choose the location. So the services are located across the world. There are some services that are available on a global level, but when it comes to a storage account, the storage account will be created in a particular location. So I can go ahead and choose a location, and you have to go ahead and give a unique storage account name that has not already been taken up. For example, if I go ahead and give a simple name, So over here, you can see this name has already been taken. Even if I go ahead and change the name to, let's say, demo store, this has also been taken. So what you can do is go out and actually add numerals to go ahead and make the storage account more unique. Now I'm going to go ahead and leave the other settings as they are when it comes to the account, since it has a kind of general purpose. V two. This gives us access to various services that are available for the Azure Storage account. Then we can go on to Next for the networking section. We can leave everything as it is. We can go on to data protection for these services and Azure; there are a lot of features that are in place even when it comes to the storage account. Over here, I'm trying to give you an example of the creation of a resource in Azure. So I'm going to go on to the last screen, which Review and Create," when you can get all of the information that is based on all of the previous screens, and then I can go ahead and create my storage account. Over here, you will actually get all the notifications in the Azure Portal. So over here, you can see the deployment of the resource is in progress. Now the creation of the storage account should just take a couple of minutes. Depending upon the type of resource that you create, there is a different duration for the creation of the resource itself. So let's come back once we have the resource in place or the deployment is complete. So now I've got a notification that the deployment has succeeded. Now I can directly click on this button to go ahead and open the resource. Now for your storage account, I can just go ahead and hide this so that we get a better view of the storage account itself. So, for the storage account, there are numerous features available on the left side. So, for example, if you want to go ahead and look at the encryption feature, you have to go on to the encryption part over here if you want to look at networking. So there are a lot of aspects that are available for every resource that you actually create in Azure. So over here we have the details of a storage account. Now on the left-hand side, if I go ahead and scroll down, I can go on to something known as the Blob service. So the Blob service allows us to go ahead and upload objects such as images, videos, or even files onto the service itself. I can go on to containers. And over here, in order to go ahead and start storing your objects using the Block service, you have to create something known as a container. So over here, I can go ahead and create a container. I can go ahead and give a name for the container. Let me just give it as "blob" anonymous access for the public access level. So this allows us to go ahead and access the data in this container. As an anonymous user, we are trying to reduce the security control of the container itself. Normally, when you are starting out, using the service is fine, but in a production-based environment, you should actually go ahead and not ensure public access level. But if you're just trying to get along, this should be fine. You can then go ahead and hit Create. Now you can go on to the container itself, and you can start uploading files onto the container itself. So if I go ahead and click on this button, I can actually go ahead and choose a file from my local system. So over here on my local system, I'm just browsing into one of my folders and choosing a simple Excel workbook. So let me go ahead and hit on "Open" so I can now go ahead and upload this onto the container. So over here, you can go ahead and start storing your files. If you go to the file itself, you can go ahead and click on the file over here if you go on to edit. So over here, since it's an Excel base file, we don't have the ability to go in and actually render it over here. But over here, you can see that if you have a text-based file, you can go ahead and see the details of the file over here itself .And there are many more options for rendering different types of other files. However, if you go to the overview, every object in the blob service receives something known as a URL. If I go ahead and copy that URL onto the clipboard, if I go on to a new tab, and if I go and just paste the URL, it will actually go ahead and download that Excel sheet file. I can go ahead and open that file up, and I can see the data in the file. So if you want to go ahead and have data stored in a database, you can actually go ahead and make use of a storage account, right? So in this chapter, I just want to kind of go through the creation of simple resources in SEO.
