Clustering Liferay in Amazon Cloud
Description
The Global Learning and Observations to Benefit the Environment (GLOBE) program was founded in 1995 by a coalition of NASA, NOAA, the NSF. The GLOBE Program is the world's largest international science education program supporting 111 countries, over 25,000 schools, and more than 25 million data points. NASA looked to Raytheon Web Solutions to provide a more cost efficient solution to host the GLOBE.gov Web Portal. In this case study, we will look at how Raytheon Web Solutions successfully migrated the GLOBE.gov Enterprise Liferay Portal to the AWS Amazon Cloud. We will look at the benefits and technical challenges presented with migrating a clustered Liferay Portal to the cloud. We will also examine the problems presented with the migration and what factors drove the technical solution. The topics covered will include data migration, multicast vs unicast, tomcat clustering, and ehcache. The presentation will discuss the factors that drove the cloud solution, the cost benefits, and technical challenges encountered while migrating GLOBE to the AWS Amazon Cloud.
