Applications MUST NOT use sticky sessions, nor any form of 2nd-level caching requiring similar container affinity. HSPC's reverse proxy environment routes pseudo-randomly and has no mechanism for supporting these types of applications.
Data Persistence
All containers are assumed to be ephemeral unless you tell us otherwise. If you have persistence requirements – usually external database access or disk access – let us know so we can find a workable solution.
Swarm Updates
Auto-rollout of updates begins with container management instructing the sandbox server to download the appropriate image. Once downloaded, existing containers are killed at a 15s delay while updated containers are starting up. As services are configured in a swarm, and there may be more than one container running at any given time. During the short (usually <1m) rollout periods, both old and new instances will be responding to requests if the cardinality is greater than 1.
