Yes. Thank you, Raju. A year into the pandemic, all the industries cutting across small, medium and large have accelerated their digital transformation and cloud adoption drives to be able to sustain and grow their businesses in a changed environment. Work from anywhere, movement to hybrid cloud platform, strengthening of disaster recovery plans to enable business continuity, application modernization, all these market trends find a natural solution in Sify's Cloud@Core model and offerings. The other important highlight is the growth of hyperscale cloud service providers and OTT players in India, which, on one hand, is accelerating our data center colocation business and on the other hand, strengthening our hybrid cloud offerings. Overall, we are on the right side of the same path.
I would now like to expand on the business highlights and our growth drivers. Revenue from Data Center Services grew by 22% over last year. Segment-wise, revenue from Data Center Services grew by 45%. Cloud and Managed Services grew by 21%, and Technology Integration Services grew by 19%, while Application Integration Services fell by 19% over last year. Revenue from Network-centric services fell by 7% over last year. Segment-wise, revenue from Data and Managed Services grew by 4% and Voice business fell by 35% over last year.
Let me now expand upon the growth drivers. The pandemic has accelerated the primary growth drivers in the market for cloud adoption led by digital initiatives and transformation. This trend is triggering movement of our cloud from on-premise data centers to hyperscale public cloud and hosted cloud in varied degrees based on the digital objectives of the enterprises.
This results in transformation of the traditional network architecture and transformation at the edge, which connects the end user. The need for digital services like analytics, data lakes, IoT, et cetera are shifting the balance to adoption of hybrid and public cloud versus private cloud. Collectively, these trends are generating opportunities for full-scale cloud data center and network services, network service providers with digital service schemes.
Let me summarize the categories of customers who are signing up with Sify.
