Azure REST APIs are a great way to manage your Azure resources. You can use them to create, update, delete, and list resources, as well as get information about them. In many cases, the tools provided by Microsoft - like Azure CLI and Azure PowerShell, do not provide the functionality you need and thus you have to turn to the APIs. As an example, we're going to create a script that will get the size of the storage consumed by Recovery Services Vaults, that is available in Azure Portal but not in the command line tools. So If you have a lot of vaults and you need the size of the storage behind them, you need to automate the process using the Azure APIs. Below is the entire script, but don't dive right in, let's take it a step at a time! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 8...

Modern applications are usually developed with cloud-native principles in mind, there are however some that may have particular requirements in terms of storage. When developing for containers, the need for a ReadWriteMany storage may arise, which may turn into a problem when cloud services fail to match the requirements, especially the ones related to performance. One of the solutions to this problem is the Rook - Ceph combination. Ceph is an open-source software-defined storage platform that implements object storage on a single distributed computer cluster and provides interfaces for object-, block- and file-level storage. Rook, on the other hand, helps perform all the administrative tasks such as deployment, configuration, provisioning, scaling, and more. A multi-zone AKS cluster is the perfect home for Rook and Ceph. The cluster is spread across three data centers and so is the data handled by Ceph. This increases the SLAs of the services running on the cluster and at the same...
