Our work will complement the work performed by these authors adding also insights from grey literature as well as more recent works on the topic.
AI是什么？
More precisely, AI is a technological domain with core components such as Machine Learning (ML), Deep Learning, Natural Language Processing (NLP) platforms, predictive Application Programming Interfaces (APIs), and image and speech recognition tools [29].
AIOps是什么？
Gartner的定义
"AIOps platforms utilize big data, modern machine learning and other advanced analytics technologies to directly and indirectly enhance IT operations (monitoring, automation and service desk) functions with proactive, personal and dynamic insight.
AIOps platforms enable the concurrent use of multiple data sources, data collection methods, analytical (real-time and deep) technologies, and presentation technologies."
Forrester 的定义
“AIOps primarily focuses on applying machine learning algorithms to create self-learning and potentially self-healing applications and infrastructure.
A key to analytics, especially predictive analytics, is knowing what insights you’re after.”

好处
AIOps is relatively young and far from a mature technology, even so, it already has reported some potential benefits.
Monitoring IT work. 强大的RCA，快速的troubleshooting
AIOps solutions monitor and analyze the activities performed in an IT environment (both hardware and software), e.g. processor use, application response times, API usage statistics, and memory loads [18, 61].
These analytics and ML capabilities allow AIOps to perform powerful root cause analysis that speeds up troubleshooting and solution to difficult and unusual problems [47, 59]
e.g., if the workload traffic exceeded a normal threshold by a certain percentage, the AIOps platform could add resources to the workload or migrate it to another system or environment much like a human admin does [56].
Proactive IT work. 主动运维，Proactive相对的是Reactive，依赖预测技术
AIOps reduces the operational burden of IT systems and facilities with constructive actionable dynamic insight by utilizing big data, machine learning, and other advanced analytics technologies to boost IT operations [47, 58].
This means that AIOps platforms can provide predictive warnings that allow potential issues to be solved by IT teams before they lead to slow-downs or outages.
In fact, a survey from 6000 global IT leaders about AIOps revealed that 74% of the IT professionals want to use proactive monitoring and analytics tools [48].
However, 42% of them are still using monitoring and analytics tools reactively to detect and fix technological challenges and issues.
挑战
Low-quality data.
The performance of the AIOps highly depends on the quality of the data [53].
While major cloud providers capture terabytes and even petabytes of telemetry data every day/month today, there is still a shortage of representative and high-quality data for developing AIOps solutions [22].
It is simply becoming too complex for manual reporting and analysis.
In this scenario, current issues are noisy data, irregular or inadequate reporting frequencies, and even inconsistent naming convention [51, 53].
Besides, essential pieces of information are “unstructured” types of data presenting poor data quality[53].
Therefore, a constant improvement of data quality and quantity is essential, taking into account that AIOps solutions are based on data [22].
Identifying the use cases. 找到场景怎么使用AIOPS，本身要求对于业务的深入理解
Use cases in the AIOps is the process of analyzing and identifying the challenges and opportunities across the IT operation environment [51].
In addition, building the models to solve these problems and monitoring the performance of the developed model [55].
Companies believe using AI and ML-related features will increase the efficiency of current development within the organization [52].
However, without identifying the underlying issue AIOps implementation might not be effective [51].
As AIOps solutions require analytical thought and adequate comprehension of the whole problem space such as market benefit and constraints, development models and, considerations of system and process integration [22].
Therefore, the organization should start examining underlying systems, applications, and processes from the top level and decide the integration of AIOps to have the greatest leverage [51].
Traditional engineering approach. 没有成熟的实施方案，落地比较困难，
Successful AIOps implementation requires significant engineering efforts [22].
As it is relatively young and far from mature technology only limited AIOps-engineer are available [22].
Therefore, instead of focusing on building new AIOps initiative, reshaping the existing approach and processes in the organizations is important for the new realities of digital business [54, 55].
These works indicate that traditional approaches do not work in dynamic, elastic environments.
However, ideal practice/principles/design patterns are yet to be established in the industry [53].
