In this Q&A, James Miller, vice president and chief technology officer of DXC’s Cloud and Platform Services, says hybrid IT enables organizations to bridge the old to the new and use modern technology to get the most out of legacy environments — but IT has to evolve to get the most out of the opportunity.


Q: Why do enterprises need hybrid IT? 

AIt’s all about balancing old and new. In today’s digital reality, enterprises need strategies that enable traditional IT to work in harmony with analytic-intense data streams located on-premises, in the cloud and at the edge. Pressure to move information processing close to the data — due to high data volumes, data variety, and the need to minimize analytic latency — is forcing enterprises into public clouds at a remarkable rate. Even enterprise transactional systems are beginning to migrate. As the industry undergoes this dramatic transition, hybrid IT operations that span on-premises, data center, cloud and edge become mandatory.

Hybrid IT embraces integrated business-IT teams, with a focus on IT services and a shift to API-driven information-sharing for accelerated business performance. In a nutshell, hybrid IT takes modern approaches, including DevOps, automation, community sourcing, machine learning and artificial intelligence (AI), and pulls the legacy environment forward to provide more business value.


Q: How does the internet of things (IoT) play into a hybrid IT strategy? 

AIoT devices mean the enterprise has to extend its capabilities to the network edge, where the devices are. These edge devices are generating data that must be analyzed. Companies need to create a multi-tier architecture, where some data is processed at the edge in near real time, and some is aggregated and processed at the core using machine learning and AI to gain business insights.


Q: What kinds of changes need to be made with processes and people to enable hybrid IT?

AAs organizations move workloads to the cloud, the IT operations function should adapt to manage both on-premises and cloud-based applications. This new model, called CloudOps, can provide continuous integrated operations in a multi-cloud environment to enable rapid response to events, incidents and requests.

Instead of having tickets passed from one person (department) to the next, you have a multiskilled, high-performance team that rapidly addresses issues. Making that switch is a challenge for most organizations with a legacy operations environment. It requires re-skilling the IT workforce.

Eventually, log data can be leveraged to automate certain actions and resolve incidents.

Existing governance processes, gates and approval procedures designed for legacy IT environments are no longer appropriate in the new hybrid IT environment. Companies should revamp their change management systems to allow changes to happen quickly and, using automated workflows, to reduce manual intervention.
