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 bunch of providers. Repeatedly monitoring the platform service well being allows our groups to promptly detect and mitigate incidents that will influence our prospects. 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 dimensions 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 Group to share how they make use of the Triangle System utilizing AIOps to drive faster time to decision to finally 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 complicated because the incident logged in opposition to a selected service is probably not the foundation trigger and will stem from any variety of dependent providers. With a whole bunch of providers in Azure, it’s almost inconceivable for anybody individual to have area data in each space. This presents a problem to the effectivity of handbook prognosis, 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 as a result of enhancing reasoning potential of enormous 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 task choices for incidents, saving time and lowering redundancy. These brokers use LLMs as their mind, permitting them to suppose, cause, 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 potential to “suppose” comprehensively. This method won’t solely enhance effectivity but in addition 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 crew and is encoded with area data of the crew to triage points. It has two superior capabilities: Native Triage and World Triage.
Native Triage System
The Native Triage System is a single agent framework that makes use of a single agent to characterize every crew. These single brokers present a binary resolution to both settle for or reject an incoming incident on behalf of its crew, 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 crew to which the incident must be transferred to, primarily based on the TSGs.
As proven in Determine 1, the Native Triage system begins when an incident enters a service crew’s incident queue. Based mostly on the coaching from historic incidents and TSGs, the only agent employs Generative Pretrained Transformer (GPT) embeddings to seize the semantic meanings of phrases and sentences. Semantic distillation entails extracting semantic info from the incident that’s intently associated to incident being triaged. The only agent will then resolve to just accept or reject the incident. If accepted, the agent will present the reasoning, and the incident can be handed off to an engineer to evaluation. If rejected, the agent will both ship it again to the earlier crew, switch to a crew indicated by the TSG, or hold 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 strategy of onboarding. The preliminary outcomes are promising, with brokers attaining 90% accuracy and one crew noticed a discount of their TTM of 38%, considerably lowering the influence to prospects.
World Triage System
The World Triage System goals to route the incident to the proper crew. The system coordinates throughout all the only brokers by way of a multi-agent orchestrator to determine the crew that the incident must be routed to. As proven in Determine 2, the multi agent orchestrator selects appropriate crew candidates for the incoming incident, negotiates with every agent to seek out the proper crew, additional lowering TTM. This can be 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 World Triage System, brokers will proceed to develop their data and enhance their decision-making talents, drastically enhancing not solely the consumer expertise by mitigating buyer points shortly but in addition enhancing developer productiveness by lowering handbook toil.

Trying 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 few of the methods we plan to do that embrace:
- Prolong the incident triage system to work for all groups: By extending the system to all groups, we goal to boost 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 accountable for the difficulty: Optimizing LLMs to shortly determine, correlate, and advocate options will considerably velocity up the troubleshooting course of. It permits the system to supply exact suggestions, lowering the time engineers spend on debugging and resulting in sooner decision of points for purchasers.
- Broaden auto mitigating identified points: Implementing an automatic system to mitigate identified points will scale back TTM enhancing buyer expertise. This may even scale back the variety of incidents that require handbook intervention, enabling engineers to give attention to delighting prospects.
We first launched AIOps as a part of this weblog sequence 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 important function at this time to foretell, defend, and mitigate failures and impacts to the Azure platform and enhance buyer expertise.
By automating these processes, our groups are empowered to shortly determine and handle points, guaranteeing a high-quality service expertise for our prospects. Organizations trying 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.
