An existing Java application (pure java) has to be modified and testet to be hosted on Heroku. (Currently it's served by a conventional webserver.) This Java server application provides live and static data for a mobile app. No web output. In addition we need a way to host Cassandra in the cloud. A possible working solution must be provided, e.g. which hosting service should be used or what else needed to get this running together with the Java app in Heroku. The java app uses the Cassandra database for data storage. Also 2 bugs need to be fixed: - Application level: A bug in application codebase that cause application fail that need to be fixed. Or an enhancement that requires application code change. - Infrastructure level: CPU/Memory/Disk/Network issues cause service failure. Your offer should include the possible hours of work to do these things.
