GENERAL DISTRIBUTION6

WHAT ARE CONTAINERS?It depends who you ask...

● Sandboxed application processes on a shared Linux OS kernel

● Simpler, lighter, and denser than virtual machines

● Portable across different environments

● Package my application and all of its dependencies

● Deploy to any environment in seconds and enable CI/CD

● Easily access and share containerized components

WE NEED MORE THAN JUST CONTAINERS

Lifecycle and healthKeep containers running despite failures

DiscoveryFind other containers on the network

MonitoringVisibility into running containers

SecurityControl who can do what

ScalingScale containers up and down

PersistenceSurvive data beyond container lifecycle

AggregationCompose apps from multiple containers
