- [Instructor] I'm in the Microsoft Azure portal and I'm going to create a storage account and by creating a storage account I'm going to be able to add redundancy. It's going to start the wizard that will allow me to create the storage account. Inside the storage account, I can create various different types of storage, such as blob storage, V1, V2 and other types of things. Now, if you were to create storage that's shared on premises, in order to have redundancy, you have to do one of various different things. You have to either have clustering set up or distributed file system or virtual machines that are replicated to another server and all those things work but they require additional licenses, additional hardware, all different kinds of costs. If you just want to create simple storage that's redundant, we can do that in Microsoft Azure, as I'll show you in this demonstration, and there's lots of different types of redundancies and high availabilities available on all different types of Azure resources. This is just one of those that I'm going to demonstrate. Under subscriptions, if you haven't created one yet, you can do that by clicking on the dropdown. Resource group. This is a resource group that I've already created, although you can choose to create a new one if you'd like, and it just allows us to group various different Azure resources into various different resource groups. In case you have multiple people using this in the same Azure portal in the same Azure tenant. Now I'm going to create the storage account name. And this has to be a name that hasn't been used yet. I'll call it Azure store LIL for LinkedIn learning. You cannot use numbers at the beginning of the name and you cannot use capital letters. And here's one of the most important parts of our redundancy and that is whether or not you want to do geo-redundant storage or you'd like to do any one of these other options. So let's go over those. First we have the region. You want to pick the one that's closest to you for the best response time. You certainly can choose one in another region if you'd like, but you don't have to. Under performance we've got standard or premium. If you choose premium you're going to have faster drives like SSD drives. Otherwise you'll use more standard types of hard drives. Under redundancy. If we click the dropdown, we have locally redundant storage. And what that is is it's going to have the lowest cost option as you see here but it's going to be in the same geographic location. The other option is to choose this geo-redundant storage. So if you choose geo-redundant, then it's going to keep another copy of your storage in another location. So if you have an earthquake or a major incident in your area, then your data will be safe and replicated to these other locations. Depending on which option you choose, you might see additional options such as the premium account type, different types of redundancy. It all depends on your area and what's available there. I'm going to click next to continue on and here's where you can check the box to require that the user have an Azure active directory account in order to be authorized for this resource. I think it's a good idea, but it may not apply to all different types of situations. Under the TLS version, TLS 1.2 is the highest and the best. And the one recommended, previous versions may have security issues. Under SFTP, you can certainly choose that option if you would like to be able to access using SSH. It does require an additional subscription to make that happen. You can also check the box for enabling large file shares. And if you scroll down, you can see that you may not be able to get this to work in multiple redundant storage offerings, because the file size can be up to a hundred terabytes in size, and that's just too much to replicate. So we're going to uncheck that in order to keep our redundancy and our high availability. Under the connectivity method the default is public endpoint so all networks can access it. This works out well if you have a lot of home users who are accessing the storage and you don't have that much to worry about when it comes to security. If you are more concerned about security, you can specify which endpoints by selecting the networks or choosing a private endpoint if say you have a VPN tunnel. Then there's the option for either the Microsoft network routing or the internet routing. The Microsoft network routing will get you there as fast as possible, but the internet routing does give you more options, more ways to get into the Microsoft network in case you have a problem connecting. Here are more options that you can choose in order to keep your data available in case of any types of deletion. So we have the enable point in time restore for containers and this will allow you to go back in time if you need to, to restore those containers. Then we have soft delete for blobs. So if you delete your blob storage then you'll have seven days to get it back. You also have the same thing for containers and you can change the amount of days if you'd like and the same thing for file shares. And this can be really important for your redundancy. Below that we see enable versioning for blobs. This is very similar to volume shadow service or VSS that we find in Windows servers. If you leave that check, then what's going to happen is it's going to maintain previous versions of your storage. So that way you can go back to previous versions, not just one but multiple versions of files that you can restore. Now we have encryption and we have tags for billing purposes, and then we have review and create. So you can go in and make changes if you need to by clicking on the previous button. This is just an example of one type of redundancy that the Azure portal resources can give you. Azure redundancies give CIS admins multiple options to make storage and other resources highly available.
