Evolution of Incident Management: From On-Call to SRE and the Tools You Need

The world of incident management has significantly changed in recent years. What once relied on a basic on-call team and an alerting system has evolved into a complex practice that incorporates automated incident response and SRE workflows. This blog post will explore the evolution of incident management, the challenges faced in modern systems, and how the right incident management tools can empower your team.

Importance of Reliability and Tools for Incident Management

The rise of digital products and services has led to a surge in user expectations for reliability. Customers rightly expect software to function flawlessly whenever they need it. However, achieving perfect reliability is nearly impossible. Even reaching 99.9% uptime is a significant feat. Complex engineering infrastructures make incidents inevitable. The key is to resolve issues quickly and minimize their impact.

Here are some notable outages that have impacted users on a global scale, highlighting the importance of effective incident management with the right tools:

• October 2021: A mega outage took down Facebook, WhatsApp, Messenger, Instagram, and Oculus VR for almost five hours! Users were unable to access any of these products during this time.
• November 2021: A downstream effect of a Google Cloud outage led to outages across multiple GCP products, indirectly impacting many non-Google companies as well.
• December 2022: An incident corresponding to Amazon’s Search issue impacted at least 20% of all global users for almost an entire day. The monetary impact was massive, with share prices of numerous U.S. air carriers falling steeply.
• Jan 2023: The Federal Aviation Authority (FAA) suffered an outage due to a failed scheduled maintenance, causing 32,578 flights to be delayed and a further 409 to be cancelled.

These are just a few examples, and incidents like these are far more frequent than most people realize. While businesses bear the brunt of such outages, the impact is also felt by end users, resulting in a poor user experience.

Here are some interesting statistics on the impact of poor user experience:

• It takes 12 positive user experiences to make up for one unresolved negative experience.
• 88% of web visitors are less likely to return to a site after a bad experience.
• Even a 1-second delay in page load can cause a 7% loss in customers.

This underscores the importance of resolving incidents quickly. But how can you effectively deal with incidents? Let’s delve into the challenges of modern incident management and how the right incident management tools can help.

Challenges of Modern Incident Management and How Tools Can Help

Evolving business and user needs have directly impacted incident management practices. Here’s a breakdown of the challenges and how incident management tools can address them:

Managing Complexity:

• Challenge: Distributed applications and microservices architectures can make it difficult to pinpoint the source of an incident and determine which services are affected. An increasingly complex tech stack with numerous tools can further complicate troubleshooting efforts.
• Tools: Incident management tools can provide service visibility and ownership tracking to streamline troubleshooting. These tools can help you map dependencies between services and identify which teams are responsible for each one.

Lack of Automation:

• Challenge: Many incident response teams lack sufficient automation. Manual tasks slow down response times and can lead to human error.
• Tools: Incident management tools can automate routine tasks within the incident management workflow, significantly improving Mean Time to Acknowledge (MTTA) and Mean Time to Resolve (MTTR). This can include automatic notifications, incident escalations, and even some remediation actions.

Poor Collaboration:

• Challenge: Effective communication and collaboration are crucial during incidents. Poorly managed communication can lead to confusion and delays in resolving incidents.
• Tools: The right incident management tools can simplify communication channels and keep all stakeholders informed with Status Pages. This can include features like war rooms, chat integrations, and incident timelines.

Limited Visibility into Service Health:

• Challenge: Transparency regarding incident impact, triage, and resolution is essential. Without a clear understanding of the situation, it can be difficult to effectively communicate with stakeholders or take appropriate action.
• Tools: Status pages and service health monitoring tools can address this need by providing a centralized location for all incident-related information. This can include details about the impact of the incident, the current status of the investigation, and the estimated time for resolution.

Building an Enterprise Incident Management Strategy with the Right Tools

Here are some key aspects to consider when building an enterprise incident management strategy that leverages the right incident management tools:

• Centralized Alerting and Incident Management: A unified platform can consolidate alerts from various monitoring tools, providing a centralized view of incidents and streamlining the response process.
• Automated Alert Routing and On-Call Scheduling: Effective on-call management ensures alerts reach the right engineers and includes escalation protocols for unresolved issues. Incident management tools can automate these processes, ensuring timely notifications are sent to the appropriate on-call engineers based on pre-defined schedules and escalation policies.
• Automated Incident Management: Automating repetitive tasks like incident notification, escalation, and documentation frees up valuable time for engineers to focus on resolution. Incident management tools can automate these tasks, streamlining the workflow and minimizing human error.
• Integration and Collaboration Tools: Integrating your incident management system with ITSM, chatops, and CI/CD tools fosters seamless communication and streamlines workflows. For example, integrating with chatops tools allows engineers to collaborate and troubleshoot incidents directly within their chat platform, improving communication efficiency.
• SRE Adoption: Site Reliability Engineering (SRE) practices emphasize proactive monitoring, automation, and a data-driven approach to ensure system reliability and performance. Incident management tools can support SRE principles by providing features for automated incident prevention, root cause analysis, and performance metrics tracking.

Popular Tools for Incident Management:

Several tools can empower your incident management team, including:

• PagerDuty: A popular incident management platform offering features like on-call management, alert routing, incident collaboration, and integrations with various monitoring and ITSM tools. Today a lot of other pagerduty alternatives have come up that are willing to offer the enterprise features at a minimal cost
• FireHydrant: Focuses on streamlining alert workflows with features like automated incident suppression, runbooks for automated remediation actions, and war rooms for real-time collaboration during incidents.
• Squadcast: An incident management platform designed specifically for SRE teams, offering features like automated incident response workflows, blameless post-mortem analysis, and status page management.

These are just a few examples, and the best tool for your organization will depend on your specific needs and budget. However, all of these tools share some common functionalities that can significantly improve your incident management capabilities.

Conclusion

Effectively managing incidents requires a combination of process, people, and the right tools. By implementing a comprehensive incident management strategy that leverages automation, collaboration, and SRE principles, you can ensure your systems remain reliable and resilient. The right incident management tools can empower your team to respond to incidents quickly and efficiently, minimizing downtime and maintaining a positive user experience.
