Cloud and containersIn the last four years, the cloud has changed drastically :• Heavyweight virtual machines now host small containers.• Containers are grouped into small private networks.• All interaction points are self-documented (services, storage,
ports).• Continuous integration is part and parcel with deployment.

Containers for C2MONBeing cloud-ready is not a given :• Location, location, location• Configuration and secrets• Storage claims• Outgoing connectivity• Dependencies on other containers

C2MON Container
Network Ports
Storage
Configuration
Service dependencies
• Fixed ports• No HA HTTP support
• Env variables only• No cloud configuration support
• Requires multicast support
• Expects decent I/O• World writeable flush folders

Conclusions• Containers promise a run-anywhere, scalable platform
independent experience :• Yes but mostly if you start from zero.• Knowing what to look out for before you get started :
• It may be worth upgrading part of your technology stack rather than spend time containerizing it.
• It will depend significantly on your target cloud platform.
