Coming hot on the heels of Apple's announcement last week that it is seriously getting into the healthcare game came another healthcare announcement from a US tech giant this week in the form of Amazon, although what the proposal actually entails is still a bit fuzzy.

The online retailer and cloud provider has got together with Warren Buffet's conglomerate Berkshire Hathaway and financial services firm JPMorgan Chase to explore how to provide healthcare to their tens of thousands of US employees. Speculation initially centred on whether the trio was going to try to take on America's notorious health insurers, but it looks much more likely now that the main game is to explore how technology can cut the cost of healthcare provision.
