Service Disruption Scenarios and Response Steps

1. Cloud Service Outage (e.g., AWS Services)
   • Description: An unexpected failure or outage impacting AWS services that our workloads rely on.
   • Immediate Steps:
     1. Notify the Incident Responder and Operations Manager.
     2. Use AWS CloudWatch to assess the impact and identify affected services.
     3. Initiate AWS Systems Manager Incident Manager runbooks to automate incident response.
   • Backup Procedures:
     • Activate backup servers or failover resources hosted in a different AWS region.
     • Engage with AWS Enterprise Support to escalate the issue if necessary.
   • Communication:
     • Inform stakeholders about the impact and estimated recovery time.
     • Send status updates every 30 minutes until the issue is resolved.
   • Resolution Verification:
     • Perform a full system check to ensure all services are operational before closing the incident.
2. Third-Party Software Failure
   • Description: A failure in third-party software impacting functionality.
   • Immediate Steps:
     1. Attempt to restart or reset the affected software following vendor documentation.
     2. Contact the third-party vendor support team using the Contact Information Log.
   • Alternative Solutions:
     • Use a backup software solution or manual process to maintain operations.
     • Document any workaround procedures for future reference.
   • Escalation: If the vendor cannot resolve the issue within an acceptable timeframe, escalate to a higher-tier contact.
3. Database Unavailability
   • Description: An outage or performance issue affecting the primary database.
   • Immediate Steps:
     1. Notify the Database Administrator (DBA) and Incident Responder.
     2. Switch to a read-only backup database if read operations are sufficient.
   • Backup Procedures:
     • Restore the database from the latest snapshot or backup if write operations are needed.
     • Notify all application teams to connect to the backup database.
   • Data Recovery:
     • Perform data integrity checks post-recovery to ensure no data loss or corruption.
4. Network Connectivity Issues
   • Description: A disruption in network connectivity impacting access to critical services.
   • Immediate Steps:
     1. Assess the scope of the issue (local, regional, or global).
     2. Attempt to reroute traffic using alternate network paths if available.
   • Alternative Connectivity Options:
     • Use a secondary internet service provider or virtual private network (VPN) for continued access.
   • Communication: Keep affected teams updated on progress and expected resolution times.

Backup and Failover Resources

1. Cloud-Based Resources:
   • AWS Regions and Availability Zones: Deploy resources across multiple regions and availability zones to minimize the impact of regional outages.
   • Data Backup: Regularly back up data to different geographical locations.
2. On-Premises Resources:
   • Maintain a local backup for critical services that can be activated if cloud services fail.

Communication Plan

1. Incident Notification:
   • Who to Notify: Incident Responder, Operations Manager, Support Coordinator, and relevant stakeholders.
   • How to Notify: Use email, SMS, or an incident management tool to communicate.
   • When to Notify: Immediately upon detection of a significant service disruption.
2. Status Updates:
   • Frequency: Provide updates every 30 minutes or as new information becomes available.
   • Content: Include the current status, steps being taken, and estimated resolution time.
3. Post-Incident Communication:
   • Conduct a post-mortem meeting to discuss the cause, impact, and lessons learned.
   • Distribute a detailed incident report to all relevant teams.
