New Delhi, June 1 : The public cloud services (PCS) market in India reached $6.2 billion last year, as software-as-a-service (SaaS) continued to be the largest component of the overall public cloud services market, followed by infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS), an IDC report showed on Thursday. The overall India public cloud services market is expected to reach $17.8 billion by 2027, growing at a CAGR of 23.4 per cent.

The top 2 cloud service providers captured more than 40 per cent of the India public cloud services market. The India market witnessed robust growth, driven by the accelerating digital transformation among India enterprises, and cloud service providers continuing to witness increased demand from SMBs and startups. "The accelerated digital adoption among Indian enterprises with cloud as a key enabler continued to be the prime driver of the public cloud services market in India, as cloud adoption helps enterprises drive efficiency in operations along with scalability benefits, thereby enabling them to gain a competitive advantage," said Harish Krishnakumar, senior market analyst, IDC India. /IANS
