◇Performance
◇Offload expensive parts of the architecture
◇Scale up – get the most out of one machine
◇Scale out – add more capacity with more machines

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
