Payara Cloud FAQ

Payara Cloud is a cloud-native deployment platform that provides a fully managed environment for deploying and running your Jakarta EE/MicroProfile applications. It is built on top of Payara Enterprise and offers a range of features and services for deploying, scaling, and managing your applications in the cloud.

Payara Cloud offers several key features, including automatic scaling, high availability, monitoring and metrics, security, centralized logging, seamless integration with other cloud services, and a user-friendly web-based management console.

Payara Cloud is designed to run Jakarta EE Web Profile applications written mostly in Java.

Yes, you can deploy your existing Java EE Web Profile applications on Payara Cloud without any modifications. Payara Cloud provides full compatibility with Java EE (8) and Jakarta EE (10) standards, ensuring that your applications run seamlessly.

Yes, within Payara Cloud you can deploy multiple applications within the same namespace and, you can create multiple Namespaces to host several applications.

At the moment, you should maintain a database installation yourself, in the cloud or on-premise. You can configure your database instances within your application using the standard Jakarta EE database connections constructs. These will be automatically picked and displayed on your Payara Cloud monitoring console for easy editing.

Payara Cloud can automatically scale your applications based on predefined rules or metrics such as CPU utilization, memory usage, or incoming request rates. It dynamically adjusts the number of instances running your application to match the demand, ensuring optimal performance and resource utilization.

Yes, Payara Cloud provides seamless integration with other cloud services and platforms. You can easily connect your applications to databases, storage services, message queues, and more, offered by various cloud providers.

Yes, Payara Cloud prioritizes security and provides a secure environment for your applications. It includes features like network isolation, encryption, secure access controls, and automated security updates to protect your applications and data. Your applications deploy in separate containers to isolate them from the actions of other applications. They only have partial internet exposure, which allows only applications in the same namespace to access them via private endpoints. Payara Cloud also generates SSL certificates for your applications.

At the moment, multiple users would need to access the environment using the same username and password. Fine grained access control is on the roadmap and will be released in the near future.

Payara Cloud ensures high availability by automatically distributing your application instances across multiple availability zones. In the event of a failure, it can quickly recover your application on another healthy instance, minimizing downtime.

Yes, Payara Cloud provides comprehensive monitoring and management capabilities. It offers built-in metrics and monitoring dashboards, allowing you to track the performance and health of your applications. Additionally, you can use the web-based management console to configure and manage various aspects of your applications.

No. Your current running version will be available until the new one is done deploying, which will take the place of the last running one. There is the possibility of a negligible downtime during the layover from the old to the new version. All uploaded and undeployed application versions will still be available for easy rollback at any point in time.

The runtime size specifies the amount of resources to allocate for this instance and count against the included vCPU of your subscription. The following CPU has been reserved:

A namespace in Payara Cloud is container for the isolation/grouping of resources. A Subscription can have multiple namespaces. A namespace can have multiple applications. Each deployed application in a given name space will be accessible as a context path on the namespace.

Yes this is expected behaviour. When you create a namespace and deploy an app for the first time, the full URL to the app is a fully functional domain that will need to propagate. This generally takes anywhere between 5 - 20 mins.

Once your new app binary is successfully uploaded, its status will show as configured on the dashboard. You can then click the hamburger menu to either configure it or deploy it.

The previous versions of your app will be undeployed once a new version is deployed. The status (Deployed) refers to them not being the currently active, deployed version.

You can get a 15-day free trial of Payara Cloud by creating an account at https://payara.cloud. For security reasons, you will be required to have a payment method on file. This will however, not be charged until your trial is over.
