Session Manager
System Analysis
Normal Behavior
Runs a lightweight background agent on the target instance that initiates and maintains an encrypted, outbound-only WebSocket connection to the cloud provider's central management control plane. When an operator initiates a session, the control plane authenticates the user via centralized Identity and Access Management (IAM) policies, brokers an interactive terminal channel through the established outbound connection, and streams comprehensive, tamper-evident command transcripts to centralized audit storage.
Failure Behavior
If the local instance agent exhausts CPU or memory, crashes under high I/O load, or loses outbound connectivity to the provider's API endpoints, administrators are completely locked out of the instance, eliminating emergency troubleshooting access during critical host-level outages.
Business Consequence
A collapse of the Session Manager instantly invalidates all active user authentications, logging out the entire global user base simultaneously and causing a catastrophic thunderous herd of re-authentication requests that typically brings down the identity provider.
Visual Manifestation
"A sudden flood of HTTP 401 Unauthorized responses across all services, followed by the login page crashing under a 10,000% load spike."
Satirical Behavior
"The single point of failure that remembers who you are, until it reboots and decides the entire company needs to log in again."

How do outbound network policies and API throttling cause sudden administrative lockouts in Session Manager?
Because the instance agent relies exclusively on outbound HTTPS and WebSocket connections to the cloud control plane, any misconfiguration in outbound security groups, NAT gateways, or private VPC endpoints immediately severs the agent's control channel. Furthermore, if automation scripts flood the cloud provider's session API, control plane rate limiting (throttling) will reject interactive connection attempts during emergency triage.
Why does unbuffered session transcript logging freeze interactive terminal sessions?
When Session Manager is configured to stream live terminal input and output transcripts directly to external services (such as cloud log streams or object storage buckets) for compliance auditing, any temporary write latency or API rate limiting on the storage backend exerts backpressure on the agent's stdio pipe. This causes the interactive terminal to freeze and stop echoing keystrokes until the remote write acknowledgment resolves.
