SNEAK Principle

• Scenario: case/interface
• Necessary: constrain/hypothesis
• Application: service/algorithm
• Kilobit: data
• Evolve

Do you know what’s the different between “Node” and “Server”

Eg: Monitor System?

• S: where?
  • WhatsApp or Wechat

Do you know what’s the different between “Service” and “Server”

Service	Server
Software	Machine
Process, Thread	CPU, Disk

• N:
  • If you have 1000 Machine(Swarm)
  • May be 1000 x 200(Process) = 200k Process
  • We also need to send the logs to Center Machine per/Minute
  • Query Per Second(QPS): \(\frac{1000}{60} = 16\) 1000 means 1000 Machine

How many Processes can be run at the same time in Mac?
