Announcing the General Availability of WordPress on Azure App Service
We are thrilled to announce that WordPress on Azure App Service, which was running on Public Preview since 15 February 2022, has been made Generally Available on 8 August 2022. To read the Public Preview Announcement read the blog post on The new and better ‘WordPress on App Service’ - Microsoft Tech Community.
Understanding 'Always On' vs. Health Check in Azure App Service
The 'Always On' feature in Azure App Service helps keep your app warm by ensuring it remains running and responsive, even during periods of inactivity with no incoming traffic. As this feature pings to root URI after every 5 minutes. On Other hand Health-check feature helps pinging configured path every minute to monitor the application availability on each instance. What is 'Always On' in Azure App Service? The Always On feature ensures that the host process of your web app stays running continuously. This results in better responsiveness after idle periods since the app doesn’t need to cold boot when a request arrives. How to enable Always On: Navigate to the Azure Portal and open your Web App. Go to Configuration > General Settings. Toggle Always On to On. What is Health Check in Azure App Service? Health check increases your application's availability by rerouting requests away from instance where application is marked unhealthy and replacing instances if they remain unhealthy. How to enable Health-Check: Navigate to the Azure Portal and open your Web App. Under Monitoring, select Health check. Select Enable and provide a valid URL path for your application, such as /health or /api/health. Select Save. So, is it still necessary to enable the 'Always On' feature when Health Check is already pinging your application every minute? -> Yes, please find below explanation for the same. Test App scenario: Health Check enabled (pointing to /health_check path) and Always On disabled. Started the app and sent some user requests. Observations from the Test: After the application starts up, health check pings begin following the end user's request. Please find below table representing Health-check pings following user's request to root URI. Time Bucket URL Status Request Count 2025-03-20 07:00:00.0000000 / 200 6 2025-03-20 07:00:00.0000000 /health_check 200 30 2025-03-20 07:30:00.0000000 /health_check 200 30 Subsequent Health-check pings will continue, even in the absence of user requests. However, after restarting the app and in the absence of any user requests, we observed that Health Check requests were not initiated. This indicates that Health Check does not start automatically unless application is actively running and serving requests. Conclusion: Always On ensures that the app is proactively kept warm by sending root URI pings, even post-restart. The health-check feature is useful for monitoring application availability when the application is active. However, after a restart, if the application isn't active due to a lack of requests, Health-check pings won't initiate. Therefore, it is highly recommended to enable Always On, particularly for applications that need continuous availability and to avoid application process unload events. Recommendation: Enable Always On alongside Health Check to ensure optimal performance and reliability.Transition from Alpine Linux to Debian for WordPress on App Service
We are excited to share with you that we will be transitioning from Alpine to Debian as the default Linux distribution for WordPress on App Service. While Alpine has served us well with its lightweight and performant nature, our evolving needs require a more feature-rich environment. Debian is the ideal candidate to support our next phase of development and growth. This transition will also align us with App Service Linux, which already utilizes Debian as the default Linux distribution.How to run Bash scripts in WordPress on Azure App Service
You might need to run custom Linux scripts in WordPress on Azure App Service for achieving specific goals, such as, updating Nginx settings, running WP-CLI commands, and installing system packages. This article is intended to guide you in running custom shell or bash scripts.
Issue with IndexNow Automatic Submission Indexing ‘noindex’ Pages
I need some help with Bing Webmaster, specifically the IndexNow API and Wordpress IndexNow plugin. I have outlined my issue here: https://github.com/microsoft/indexnow-wordpress-plugin/issues/60. I am either looking to get in contact with the plugin devs or a 3rd party developer to fork the plugin and add the basic feature I need: exclude URLs of a certain path from being submitted to Bing for indexing. Thanks Reed
