Seaside under GLASS

Introducing a powerful new way to deploy desktop-like web applications – GLASS: GemStone, Linux, Apache, Seaside, Smalltalk.

You may already be familiar with the advantages Seaside has over other web development frameworks. But you may be concerned that Seaside lacks native persistence or won't scale.

By running your Seaside application in GemStone/S, you'll gain a Smalltalk based Application Server and OODB that:

• Provides fully transparent persistence that doesn't require Object-Relational Mapping

• Scales to over a hundred billion objects and thousands of simultaneous connections

• Supports fully ACID transactions to handle concurrency conflicts

• Handles up to hundreds of HTTP requests per second

• Directly loads Monticello packages into a GemStone/S VM

GemStone/S is proven technology currently deployed in numerous global 500 companies in the financial, container shipping, manufacturing, and utilities sectors.

Here is a comparison of 64-bit editions of GemStone/S that work with Seaside:
