Editor's Notes
- #14: Anyone used it before? Anyone heard it before?
- #15: Hazelcast is an operational in-memory computing platform that lets companies manage data and distribute processing using in-memory storage and parallel execution for breakthrough application speed and scale.
- #17: it is under apache 2 license so you can fork hazelcast and develop your own features or product, it is just 1 jar.. rod johnson - disruptively simple
- #18: -So, How do we survive as a company? We develop enterprise features such as high density memory. So you can put huge amount of data to native memory which is not under control JVM. Another example can be SSL support.. (security feature) - Management Center after 2 Nodes Also we open sourced our clients.
- #20: Going beyond “normal amounts of data” and “normal amounts of users” This is possible with two ways: Scale up vs. Scale out Scale up: Better hardware Scale out: Cluster/Distribute
- #22: L1 - There is a sandwich in front of you. L2 - Walk to the kitchen and make a sandwich RAM - Drive to the store, purchase sandwich fixings, drive home and make sandwich HD - Drive to the store. Purchase seeds. Grow seeds..... .... ... Harvest lettuce, wheat, etc. Make sandwich.
