Growing consumption of data-heavy services is speeding up infrastructure upgrades. Moreover, opportunities like implementing open and disaggregated networking architectures and the increasing adoption of cloud-native network functions are supporting more scalable, flexible, and cost-efficient DCI deployments across enterprises and service providers.

"Services are projected to record the highest CAGR during the forecast period"
The services segment is expected to experience the highest CAGR in the data center interconnect (DCI) market due to the increasing complexity of interconnection infrastructures and the rising demand for specialized support throughout deployment, integration, and maintenance phases. As organizations adopt hybrid and multi-cloud environments, they need expert services to manage secure and high-performance DCI networks that facilitate seamless data exchange across geographically dispersed data centers. The demand for real-time monitoring, traffic optimization, and disaster recovery planning is also boosting the need for managed and professional services. Additionally, the growth of outsourcing IT infrastructure operations to service providers and the shift toward software-defined and virtualized network management are reinforcing the importance of service offerings in achieving agility, scalability, and cost-efficiency in DCI deployments.
"Communications service providers (CSPs) will hold the second-largest market share during the forecast period"
The communications service providers (CSPs) segment is expected to hold the second-largest market share in the data center interconnect (DCI) market because of their crucial role in supporting high-bandwidth, low-latency connections across large and dispersed network infrastructures. As demand for high-speed internet, 5G deployment, and mobile data usage increases, CSPs are heavily investing in expanding their network capacity and interconnection capabilities. To maintain service quality and uptime, these providers require robust DCI solutions to ensure smooth data transfer between core, edge, and regional data centers. Furthermore, CSPs are adopting network virtualization, SDN, and NFV to deliver scalable and efficient services, which further drives the need for advanced DCI technologies to accommodate evolving telecom and enterprise workloads.
"Europe to grow at a significant rate in the DCI market by 2030"
Europe is expected to grow at the second-highest CAGR in the data center interconnect (DCI) market due to the region's rapid push toward digital transformation, rising adoption of cloud-based services, and the expansion of hyperscale and colocation data centers. The European Union's strong focus on data sovereignty, GDPR compliance, and sustainable IT infrastructure is fueling demand for secure, energy-efficient DCI solutions. Additionally, governments and businesses in countries such as Germany, the UK, France, and the Netherlands heavily invest in advanced connectivity infrastructure to support AI, IoT, and edge computing initiatives.
