Application Hosting runs your applications in managed environments. An environment is one application with everything it needs, such as a load balancer, application nodes and a database. Each part is a layer, and each layer runs one or more nodes. You size layers in cloudlets, and you never look after an operating system.
This page shows where everything is, and how to read your list of environments.
Open Application Hosting
- In the side menu, select Application Hosting.
- The Application Hosting page opens with a card for each place in the section:
- Environments lists every environment on your account.
- Deploy New Environment opens the wizard that builds a new one. See Create an environment.
- Backup Storage creates the environment that database backups are kept in. See Create backup storage.
- Billing shows what your environments cost. See Read Application Hosting usage.
- SSH Keys holds the keys that can sign in to your environments. See Add an SSH key for Application Hosting.
The same places appear under Application Hosting in the side menu. Billing only shows if you can see billing on the account.
If Application Hosting isn’t on yet for your account, you see the Enable Application Hosting panel instead. See Enable a service.
Read your list of environments
- Select the Environments card, or Environments in the side menu.
- The list shows one row per environment, with these columns:
- Environment is the display name. A badge such as Cluster ×3 marks a multi-region cluster, which is a set of environments that work together across regions.
- Domain is the web address of the environment.
- Status shows whether it’s running. See the statuses below.
- Topology counts its layers and nodes, for example 3 layers and 4 nodes.
- Region is where it runs.
- Actions has Open App, which opens the running application, and View Environment.
- To narrow the list, select a status tab such as All, Running or Stopped, or type in Search environments…. Search matches the name, domain, region or service.
- To open an environment, select its row or View Environment.
A cluster row is collapsed at first. Select it to show each member environment and its region. The cluster’s status reads Mixed when its members aren’t all in the same state.
WordPress sites are listed under WordPress Hosting, not here. When you have some, a note above the list says so, with a View Sites button.
Environment statuses
- Running means the environment is on and serving requests.
- Stopped means it’s off. Visitors can’t reach it until you start it.
- Sleeping means it’s idle to save resources. It wakes up on the next request.
- Starting, Stopping, Building and Cloning mean a change is under way. The list updates by itself when it ends.
- Unknown means Lighthouse couldn’t read the state. Refresh the page after a minute.
If something goes wrong
- No Environments Yet means you have the service but no environment. Select New Environment to create one.
- No environments match this view. Clear the search or pick the All tab.
- No Application Hosting Services Yet means the service isn’t set up on your account. Select Contact Support and our team will help.
