If you don’t already have an Azure account, create a free Azure account with Azure Kubernetes Service (AKS). Rook handles the heavy lifting behind the scenes, such as provisioning and management. We’ll use Rook as our persistent storage layer for the WordPress frontend. Automating Ceph (open source software-defined storage), Rook offers storage for your Kubernetes applications through persistent volumes, providing optimal integration with applications in need of storage. Rook is an open source “incubating level” CNCF project that runs as a native Kubernetes service. However, we opted for even better performance levels while leveraging Kubernetes’s extensive stack and plugins (in Kubernetes storage solutions). Azure Files and Blob Fuse can serve multiple Kubernetes pods simultaneously. Also, a virutal machine (a Kubernetes node, specifically) can support only up to a certain number of attached disks. Using Azure Managed Disk provided adequate performance but by nature, a disk is bound to a single Pod, hence not supporting Pod scaling. All of them provide a central persistent storage layer with different performance capabilities. Azure Kubernetes Service (AKS)Īzure Kubernetes Service supports several storage options. The quick tutorial below walks through how we can address this challenge, using Rook and AKS.

All of these must be centrally shared for the same application and are not hosted on the MySQL DB tier. A WordPress application is comprised of plugins, themes, content images, and many PHP files. However, there are challenges with elastic (horizontal) scaling related to stateful configurations. There are currently many ways to support WordPress scaling, including reverse proxy caching, persistent object caching, database distribution, using CDN, and more.

One of the major benefits of using cloud computing is having the ability to better support your application by scaling based on user traffic. WordPress is a popular free and open source content management system based on PHP and MySQL.
