On this weblog, we’ll dive into how giant language fashions, generative AI, and the Triangle System assist us leverage automation and suggestions loops for extra environment friendly incident administration.
Excessive service high quality is essential to the reliability of the Azure platform and its a whole lot of providers. Constantly monitoring the platform service well being allows our groups to promptly detect and mitigate incidents that will impression our clients. Along with automated triggers in our system that react when thresholds are breached and customer-report incidents, we make use of Synthetic Intelligence-based Operations (AIOps) to detect anomalies. Incident administration is a posh course of, and it may be a problem to handle the size of Azure, and the groups concerned to resolve an incident effectively and successfully with the wealthy area data wanted. I’ve requested our Azure Core Insights Crew to share how they make use of the Triangle System utilizing AIOps to drive faster time to decision to in the end profit consumer expertise.

Optimizing incident administration
Incidents are managed by designated accountable people (DRIs) who’re tasked with investigating incoming incidents to handle how and who must resolve the incident. As our product portfolio expands, this course of turns into more and more advanced because the incident logged in opposition to a selected service is probably not the basis trigger and will stem from any variety of dependent providers. With a whole lot of providers in Azure, it’s practically unimaginable for anyone particular person to have area data in each space. This presents a problem to the effectivity of guide analysis, leading to redundant assignments and prolonged Time to Mitigate (TTM). On this weblog, we’ll dive into how giant language fashions, generative AI, and the Triangle System assist us leverage automation and suggestions loops for extra environment friendly incident administration.
AI brokers have gotten extra mature because of the enhancing reasoning capacity of huge language fashions (LLMs), enabling them to articulate all of the steps concerned of their thought processes. Historically, LLMs have been used for generative duties like summarization with out leveraging their reasoning capabilities for real-world decision-making. We noticed a use case for this functionality and constructed AI brokers to make the preliminary project choices for incidents, saving time and lowering redundancy. These brokers use LLMs as their mind, permitting them to suppose, purpose, and make the most of instruments to carry out actions independently. With higher reasoning fashions, AI brokers can now plan extra successfully, overcoming earlier limitations of their capacity to “suppose” comprehensively. This method is not going to solely enhance effectivity but additionally improve the general consumer expertise by guaranteeing faster decision of incidents.
Introducing the Triangle System
The Triangle System is a framework that employs AI brokers to triage incidents. Every AI agent represents the engineers of a selected group and is encoded with area data of the group to triage points. It has two superior features: Native Triage and International Triage.
Native Triage System
The Native Triage System is a single agent framework that makes use of a single agent to characterize every group. These single brokers present a binary choice to both settle for or reject an incoming incident on behalf of its group, primarily based on historic incidents and present troubleshooting guides (TSGs). TSGs are a set of tips that engineers doc to troubleshoot widespread patterns of points. These TSGs are used to coach the agent to just accept or reject incidents and supply the reasoning behind the choice. Moreover, the agent can advocate the group to which the incident ought to be transferred to, primarily based on the TSGs.
As proven in Determine 1, the Native Triage system begins when an incident enters a service group’s incident queue. Based mostly on the coaching from historic incidents and TSGs, the one agent employs Generative Pretrained Transformer (GPT) embeddings to seize the semantic meanings of phrases and sentences. Semantic distillation includes extracting semantic data from the incident that’s intently associated to incident being triaged. The only agent will then determine to just accept or reject the incident. If accepted, the agent will present the reasoning, and the incident will likely be handed off to an engineer to evaluation. If rejected, the agent will both ship it again to the earlier group, switch to a group indicated by the TSG, or maintain it within the queue for an engineer to resolve.
Determine 1: Native Triage system workflow
The Native Triage system has been in manufacturing in Azure since mid-2024. As of Jan 2025, 6 groups are in manufacturing with over 15 groups within the technique of onboarding. The preliminary outcomes are promising, with brokers reaching 90% accuracy and one group noticed a discount of their TTM of 38%, considerably lowering the impression to clients.
International Triage System
The International Triage System goals to route the incident to the proper group. The system coordinates throughout all the one brokers through a multi-agent orchestrator to determine the group that the incident ought to be routed to. As proven in Determine 2, the multi agent orchestrator selects appropriate group candidates for the incoming incident, negotiates with every agent to search out the proper group, additional lowering TTM. It is a comparable method to sufferers coming into the emergency room, the place the nurse briefly assesses signs and directs every affected person to their specialist. As we additional develop the International Triage System, brokers will proceed to develop their data and enhance their decision-making talents, significantly enhancing not solely the consumer expertise by mitigating buyer points rapidly but additionally enhancing developer productiveness by lowering guide toil.

Wanting ahead
We plan to develop protection by including extra brokers from totally different groups that can broaden the data base to enhance the system. A number of the methods we plan to do that embrace:
- Lengthen the incident triage system to work for all groups: By extending the system to all groups, we goal to reinforce the general data of the system enabling it to deal with a variety of points. Making a unified method to incident administration would result in extra environment friendly and constant dealing with of incidents.
- Optimize the LLMs to swiftly determine and advocate options by correlating error logs with the particular code segments answerable for the problem: Optimizing LLMs to rapidly determine, correlate, and advocate options will considerably pace up the troubleshooting course of. It permits the system to offer exact suggestions, lowering the time engineers spend on debugging and resulting in quicker decision of points for purchasers.
- Develop auto mitigating recognized points: Implementing an automatic system to mitigate recognized points will cut back TTM enhancing buyer expertise. This will even cut back the variety of incidents that require guide intervention, enabling engineers to concentrate on delighting clients.
We first launched AIOps as a part of this weblog collection in February 2020 the place we highlighted how integrating AI into Azure’s cloud platform and DevOps processes enhances service high quality, resilience, and effectivity by way of key options together with {hardware} failure prediction, pre-provisioning providers, and AI-based incident administration. AIOps continues to play a vital function right this moment to foretell, shield, and mitigate failures and impacts to the Azure platform and enhance buyer expertise.
By automating these processes, our groups are empowered to rapidly determine and tackle points, guaranteeing a high-quality service expertise for our clients. Organizations seeking to improve their very own service reliability and developer productiveness can achieve this by integrating AI brokers into their incident administration processes designed within the Triangle System.
