API Express Now Available as a Standalone Version

Posted: March 23rd, 2018Author:

Today we are introducing a new way for enterprise customers to get the benefits of using our API Express backend services.

API Express allows enterprises to quickly “mobilize” existing systems by making it easier to add RESTful APIs so that theses systems can easily be accessed from other applications including mobile or desktop apps. This enables the modernization of legacy systems without re-writing them. This is highly beneficial as many enterprises are still constrained by legacy applications that are not mobile friendly.

With API Express Standalone, enterprises are now free to deploy this service behind their own firewall, while still taking advantage of the rest of the Appery.io platform in the cloud. Enterprise customers will now be able to install API Express on demand using a Docker container. For more details about the configuration process and about installing see our documentation.

Amazon AWS Updates for the Appery.io Development Platform

Posted: January 2nd, 2018Author:

Heads up! As the new year starts, we will have to take down the development platform (App Builder) for two maintenance windows (times US Pacific).

BeginEnd
Jan. 2, 11pmJan. 3, 5am
Jan. 5, 1amJan. 5, 5am

This is all due to Amazon AWS updates that have to be performed. We will try to minimize the Appery.io development platform’s downtime as much as we can, but the downtime could last through the whole window for each window. Remember, though, all our Backend Services will continue to work without interruption during this maintenance.
