COVID-19 IMPACT

Data Center Interconnect Industry Had a Negative Effect Due to Disrupting International Deliver Chains

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and returning to pre-pandemic levels.

The COVID-19 pandemic first influenced the data center interconnect market growth because of the world supply chain disruption, delayed projects, and on-site installation activities. Lockdowns and travel bans hindered the manufacturing process of equipment, its logistics, and caused shortages of parts and a long delivery time. Most of the companies delayed the growth of the infrastructure and data center upgrades due to the economic uncertainty. Also, the low supply of workforce discouraged the installation of optical fibre networks and interconnect systems. Nonetheless, as the demand on the digital services grew, the inability to scale the infrastructure rapidly resulted in the short-term discrepancy between demand and supply. The problems experienced by service providers and hyperscale operators included the inability to sustain uptime and deal with data spikes when they were not adequately connected. Despite the market starting to recover with the increased pace of remote work and cloud usage, the first phase of the pandemic has revealed the vulnerability of hardware reliance, the cross-border supply, and the absence of robust supply chains of key DCI equipment.

LATEST TRENDS

Adoption of Software-Defined Networking for Dynamic Data Centre Interconnects

The most significant trend defining the data center interconnect market is the resultant use of Software-Defined Networking (SDN) to establish more flexible, programmable and automated interconnect architectures.
