CACHES
CACHES EVERYWHERE!

20. @gamussa @hazelcast #cloudfoundry #cfsummit17
Cache is good for…

21. @gamussa @hazelcast #cloudfoundry #cfsummit17
Cache is good for…
◇Improving performance

22. @gamussa @hazelcast #cloudfoundry #cfsummit17
Cache is good for…
◇Improving performance
◇Offload expensive parts of the architecture

23. @gamussa @hazelcast #cloudfoundry #cfsummit17
Cache is good for…
◇Improving performance
◇Offload expensive parts of the architecture
◇Scale up your – get the most out of one machine

24. @gamussa @hazelcast #cloudfoundry #cfsummit17

25. @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

26. @gamussa @hazelcast #cloudfoundry #cfsummit17

27. @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

28. @gamussa @hazelcast #cloudfoundry #cfsummit17
Problem
◇Data doesn’t fit just one machine
ONE DOES NOT SIMPLY
FIT ALL DATA IN ONE MACHINE

29. @gamussa @hazelcast #cloudfoundry #cfsummit17
◇Amount of data is
too big to fit

30. @gamussa @hazelcast #cloudfoundry #cfsummit17
◇Data is too
important to have
it only one machine
