Lecture: Container Football
for Load Balancing and Hardware Lifecycle
Background migration of Logical Volumes (LVs) during operation via MARS or DRBD is the key for a new type of Software Defined Storage (SDS) on a sharding architecture. At 1&1 Internet SE, a beta version of the Football and Pool Optimizer subproject of MARS is already used for hardware lifecycle in a pool of thousands of servers and some petabytes of storage.
This presentation explains the idea behind the LocalSharding and FlexibeSharding models, and descibes the new tools and their plugins under development (similar to Kubernetes but on stateful containers), and reports first experiences from a sysadmin perspective.
