Lab: Consul and Network Partitions

Questions:
- How does Consul behave in the different parts of a cluster during a network partition? Will it recover by itself when the partition is gone?
- Would Consul change the Raft Leader if the current leader won't be able to communicate with some nodes while some other node will?
- How does Consul perform in a lossy network?
Requirements: Vagrant, VirtualBox

Lab: Docker Swarm and Network Partitions

Questions:
- How does Docker Swarm behave in the different parts of a cluster during a network partition? Will it recover by itself when the partition is gone?
- What happens to a single-instance service when that node is getting partitioned off?
Requirements: Vagrant, VirtualBox

Lab: Kafka and Network Partitions

Questions:
- Does a Kafka cluster of 3 nodes survive a rolling restart of the nodes without losing a single message?
Requirements: Vagrant, VirtualBox
