App role and permissions
Users granted access to an organization’s VIP Dashboard with an Org guest role can only interact with an organization’s applications for which they also have an assigned App role.
PHP
PHP is under active development, and runs on all WordPress environments. As new versions are released, WordPress VIP customers are encouraged to prepare their application code for a PHP version update as soon as possible.
Software Versions management
The versions of software that are deployed to a WordPress or a Node.js VIP Platform environment can be managed in the VIP Dashboard or with the VIP-CLI command: vip config software update <wordpress|php|nodejs|muplugins> <version> [options].
Origin servers
WordPress VIP maintains several origin data centers worldwide where VIP Platform environments are hosted. Origin servers for WordPress environments have application, database, batch, and object cache (Memcached) containers. Origin servers for Node.js environments have at minimum a Node.js application container and in some cases, a Redis container.
PHP error reporting
Output from PHP error reporting can be helpful for debugging issues in application code.
Deployment validation for Node.js applications
Harmonia is a Node.js deployment validation testing framework developed by WP VIP to identify issues that could prevent application code from building, deploying, or working as expected before that code is deployed to a production environment.
