Deployment Matrix
Liferay Portal wants to make it a reality the J2EE promise of write once run anywhere so you can reuse your existing resources and deploy the portal the way you want to when you want to. Reuse what you have or use what's free so you can stick with your budget and get an immediate return on investment that everyone can be happy with.There are 650 ways you can deploy the portal, with more ways to come as we add support for Resin. Is there another application server or database you use that is not IN this list? Contact US at staff@liferay.com and we'll add support for it as soon as possible.
