8. KUBERNETES
 Containerization is the Key
 Consistent repeatable, reliable deployment on a wide variety of systems
 Who will manage the systems
 You ? Scripts? A system you write ?
 Kubernetes manages your cluster
 Deploys and monitors containerized workload

9. DECLARATIVE API
 Before
 You: provide exact set of instructions to drive the desired state
 System: executes instruction
 You: monitor system and provide further instruction if it deviates
 After
 You: define the desired state
 System: works to drive towards that state

10. Cloud native computing uses an open-source software
stack to deploy applications as microservices,
packaging each part into its own container and
dynamically orchestrating those containers to optimize
resource utilization.”
