FLEXIBILITY

Eberhard Wolff - @ewolff

Flexibility ! Tuning possible ! E.g. JVM parameters ! Load balancer configuration ! Can even use your own system images !  i.e. can add software, fine tune … ! Can log into running servers ! Session handling can be tuned ! Use EC2 if Elastic Beanstalk not flexible

enough
