Background

Digital transformation has promoted the development of new business forms in all walks of life, and also brought a large number of digital applications. In order to support the characteristics of digital applications such as highly concurrent, unmanned, distributed and periodic, new technologies such as public cloud, microservice, SDWAN, big data, container and virtual desktop have appeared in the IT field. For IT O&M departments, the increasing number of objects involved in O&M, the increasing complexity of O&M, and dramatically increasing IT service requests make the traditional passive IT O&M delivery impossible to meet the IT O&M needs in the digital age. It has become the mainstream to turn IT O&M into services, turn IT services into products and deliver IT services in an operational way.
