Key features – PB Docs 2021

1. The installable cloud app can
   support almost all of the features of
   PowerBuilder.

   The installable cloud app is the cloud version of a
   PowerBuilder application; it is installed on the client, and can
   be launched directly from the desktop. But in contrast to
   browser-based apps, installable cloud apps are deployed with
   native PowerBuilder code (rather than converted to JavaScript)
   and run on the client’s PowerBuilder virtual machine (PBVM).
   Minimum code changes are required for the app deployment. The
   PBVM is exactly the same one used by the PowerBuilder classic
   client/server apps.

2. The installable cloud app runs in
   n-tier architecture.

   The installable cloud app makes HTTP or HTTPS calls to
   PowerServer and then PowerServer connects to the database and
   executes SQL queries. PowerServer can be installed on any Web
   server running Windows or Linux or docker or cloud server.
   PowerServer contains an API server which uses standard REST APIs
   with REST security to handle the HTTP/HTTPS requests from the
   client. PowerServer also contains a data server which uses .NET
   DataStore to handle the data-related requests. Currently .NET
   DataStore supports ASE, SQL Server, Oracle, SQL Anywhere,
   PostgreSQL, MySQL, HANA, and SQLite.

3. The installable cloud app is
   installed over the Internet and automatically and incrementally
   updated.

   To install an installable cloud app on the client machine,
   you access the application URL in a Web browser. You only need
   to use the Web browser to obtain the installable cloud app for
   the first time. After that, you can directly run the app from
   the desktop. And if any updates are available, the app will be
   automatically and incrementally updated.

4. The installable cloud deployment can
   be a full replacement for the traditional PowerServer Web
   solution.

   The installable cloud app can be installed on a Windows
   client, but not on any mobile client such as iOS or Android. The
   installable cloud deployment option can be used as a replacement
   for the traditional PowerServer Web solution. But for the
   PowerServer Mobile solution, the user will need to manually
   implement the client UI logic.

Note

You must have a PowerBuilder CloudPro license in order to
use the PowerServer deployment features in the PowerBuilder IDE;
and you must run PowerBuilder IDE as administrator in order to use
the PowerServer deployment features.
