Research firm IDC recently released its global market predictions for 2015. And the firm predicts that spending on Internet of Things (IoT) will exceed $1.7 trillion, jumping 14% year over year. IDC expects nearly 15 billion devices will be sold in 2015. What's more, by 2020, IDC expects that spending to climb to $3 trillion and nearly 30 billion devices. And that's good news for both Intel and Cisco.

Intel's push into Internet-of-Things has generated a lot of excitement about its future. But Internet-of-Things is more than just a new buzzword. The term, which was first used more than a decade ago by British tech pioneer Kevin Ashson, refers to objects and devices that are virtually connected in the Internet. It's become a market Intel plans to dominate.

Last year, Intel placed huge bets in wearable technology by buying Basis Science, a company that specializes in wearable devices for health and wellness applications. Intel is also working on chips to power objects like door locks and thermostas that can be uniquely identified and controlled via the Internet.

Not to mention, with the growth and popularity of fitness apps and the new wave of medical devices, Intel wants to bring safety and tracking features to those devices. To better showcase its progress and growth in these new areas, Intel will begin reporting Internet of Things areas as a separate business segment in its financial reporting structure.

This means in 2015 Intel plans to grow its Internet of Things business, a segment that's now already growing at a rate of more than 30% year over year. To the extent Intel can capture a meaningful chunk of IDC's 2015 prediction of a $1.7 trillion market, Intel will be a force to be reckoned with.

For similar reasons, Cisco's shares should continue to climb in 2015. Cisco's versions of Internet-of-Things, called the "Internet-of-Everything," will fuel its growth in the year's ahead, even though Cisco is already the world's largest cloud appliance provider. In fact, CEO John Chambers said the Internet-of-Everything will help Cisco become the No. 1 IT solution provider.

Aside from saying Internet-of-Everything an untapped $14.4 trillion market, Cisco estimates that 99.4% of devices that could be connected to the Internet are not connected. According to Cisco, 1.5 trillion connectable things that exists globally only 10 billion are reachable via the Internet.

Like it did at the height of the Internet surge, Cisco plans to be the main conduit to connect those devices. And IDC's prediction makes Cisco a strong bet to gain share in this market, because aside from already having the enterprise network expertise, Cisco's advances in security (both logical and physical), gives it an added advantage over vendors that focus on just IoT deployments.

All told, early adopters of IoT will emerge leaders and capitalize on IDC's predictions. After already dominating the market in 2014, both Cisco and Intel look well-positioned to make more money for investors in 2015 and beyond.
