@gamussa @hazelcast #cloudfoundry #cfsummit17 Applications are like onions Applications have
layers

@gamussa @hazelcast #cloudfoundry #cfsummit17 Cache is good for… ◇Performance ◇Offload
expensive parts of the architecture ◇Scale up – get the most out of one machine ◇Scale out – add more capacity with more machines
@gamussa @hazelcast #cloudfoundry #cfsummit17
@gamussa @hazelcast #cloudfoundry #cfsummit17 Caching use cases: ◇Performance ◇Offload expensive
parts of the architecture ◇Scale up – get the most out of one machine ◇Scale out – add more capacity with more machines ◇Usually very fast and easy to apply
@gamussa @hazelcast #cloudfoundry #cfsummit17 Problem ◇Data doesn’t fit just one
machine ONE DOES NOT SIMPLY FIT ALL DATA IN ONE MACHINE
@gamussa @hazelcast #cloudfoundry #cfsummit17 ◇Amount of data is too
big to fit
@gamussa @hazelcast #cloudfoundry #cfsummit17 ◇Data is too important to have
it only one machine
