Reliance Industries Ltd on Monday announced a partnership with Microsoft's Azure cloud platform, in a move that deepens the offerings of its Jio telecoms unit while posing a direct challenge to rival cloud services providers such as Amazon.com and Alphabet's Google.

As part of the 10-year alliance, Jio will build data centres across India that will be hosted on Microsoft's Azurecloud, Reliance Chairman Mukesh Ambani told shareholders at the company annual shareholders' meeting.

"We now have the capability to develop truly India-native solutions, including speech recognition and natural language understanding for all major Indian languages and dialects," said Ambani, Asia's richest man with a net worth of $46.2 billion according to Forbes.

Reliance's foray into the cloud services market - essentially selling computer services such as website hosting and data storage - could intensify competition in an Indian market dominated by Amazon Web Services (AWS), say analysts.

Ambani disrupted India's telecoms industry in late 2016 when he launched Jio with free voice and cut-price data plans, pushing some rivals out of business and forcing others to match tariffs and consolidate in a crowded sector that once comprised more than 10 carriers.

"Other cloud players like AWS and Google will have to come up with new, perhaps cheaper pricing models for India," said Satyajit Sinha, an analyst at tech consultancy Counterpoint.

Ambani has always dubbed Jio a technology company and used it to launch internet-enabled devices, deliver entertainment services, build fibre broadband and develop other offerings.

The Reliance-Microsoft partnership could help Jio extend its services to India's booming start-up ecosystem.

On Monday, addressing Reliance shareholders via a recorded video message, Microsoft's Indian-born Chief Executive Satya Nadella said: "Together, we will offer comprehensive technology solutions – from compute and storage, to connectivity and productivity – to small and medium businesses everywhere in the country."

PRICE WAR

Jio would provide free connectivity and cloud infrastructure to start-ups, Ambani said, adding the company would offer a "bundle of connectivity, productivity and automation tools" to micro, small and medium business for as little as 1,500 rupees ($21.05) a month.

"This pricing of elementary services is really the rock bottom price," said Naveen Mishra, of tech researcher Gartner.

Rivals such as Amazon Web Services and Google offer similar services at multiple times that price and technology analysts said Ambani's move could spark a price war in the Indian cloud market, expected to grow at an average 23% annually over the next five years to touch $5.6 billion.

Amazon's cloud services unit declined to comment on the matter. Google did not immediately respond to a request for comment.

"We definitely will reassess whether we should keep using AWS or something else because storage is a huge cost," said Aprameya Radhakrishna, the founder and CEO of Vokal, an audio-video knowledge-sharing platform similar to Quora.

"India is a price-conscious nation in general and anything which is competing on price will definitely get attention."

Reliance's big push into cloud services also comes as India, one of the world's fastest-growing web services markets, is framing a data privacy law, drafts of which have emphasized storage of key consumer data locally.

The country's central bank has also asked foreign firms such as Mastercard and Visa to store payments data solely in India.

"Companies that have a fairly mature IT adoption or those that are playing with a lot of Indian consumer data, they might prefer to move to (Reliance) because this data is guaranteed to be stored locally," said Krishna Iyer, an independent technology advisor who was previously a senior executive at cloud services firm Akamai Technologies.
