Communication Protocol
Secure Connection Establishment
The communication between the server and agent is initiated through a secure connection. This is typically achieved using HTTPS or another secure transport layer protocol.
Authentication and Authorization
Upon connection,the agent authenticates itself with the server. Authentication is commonly implemented using tokens or certificates. Auth 2.0 is often employed for secure API access, ensuring that only authorized agents can communicate with the server.
Encrypted Data Transmission
All data transmittedbetween the server and agent is encrypted to ensure confidentiality. This encryption is typically implemented using industry standard encryption algorithms like AES 256. TLS/SSL protocols are commonly used to establish a secure channel for data transmission.
Data Flow
Configuration Retrieval
The agent requests configuration data from the server based on the application's needs. This can include retrieving the latest configurations for the application or fetching specific configurations for different environments.
Deployment Requests
When a configurationchange occurs or a new version is available, the server initiates a deployment request to the agent. This request includes information about the updated configuration, version, and any specific instructions for deployment.
Asynchronous Messaging
Asynchronous messagingmechanisms, such as message queues (e.g., RabbitMQ), may be employed to facilitate efficient communication. Queues help decouple the communication process, allowing the server and agent to operate independently, improving fault tolerance and scalability.
Interaction Patterns
Polling
In a polling-based model, the agent periodically queries the server for configuration updates. This pattern is suitable for scenarios where real-time updates are not critical, and the agent can afford to periodically check for changes.
Push Notification
In a push-basedmodel, the server proactively notifies the agent of configuration changes. This pattern is suitable for scenarios where real-time updates are crucial, and the agent needs to respond promptly to changes.
Webhooks
Webhooks providea mechanism for the server to notify the agent of specific events, such as configuration updates. The agent registers a callback URL with the server, and when an event occurs, the server sends an HTTP request to the agent's URL.
Error Handling
Acknowledgments
The agent acknowledges the successful receipt of configuration changes or deployment requests. This acknowledgment helps the server track the status of each agent and ensures reliable communication.
Retry Mechanism
In case of communication failures, a retry mechanism may be implemented. The server retries sending the configuration or deployment request to the agent for a specified number of times or until a successful acknowledgment is received.
Communication Security
Token Rotation
To enhancesecurity, tokens used for authentication may be rotated periodically to limit exposure and reduce the risk of unauthorized access.
Certificate Renewal
If certificatesare used for authentication, a certificate renewal process may be implemented to ensure that communication remains secure over time.
Audit Logs
Both the serverand agent maintain detailed audit logs of communication events. These logs can be useful for troubleshooting, monitoring, and ensuring compliance with security policies.
