Digital transformation has brought along various benefits for enterprises and organizations. These benefits include accelerated application delivery, O&M costs, increased IT infrastructure scalability, and increased data storage and computing resource availability on the fly. The large-scale expansion of web-based services using multi-cloud or hybrid cloud environments has also created numerous challenges for IT teams. Strategists have to create an effective mechanism that ensures security and operational efficiency for IT systems.

AIOps is a mechanism that mixes the power of Artificial Intelligence (AI), machine learning techniques, and big data analytics to enhance IT operations.
