Cloud technology has evolved significantly over the years, but what the public sees today is still largely confined to cloud storage. While there's a lot of excitement about the future of the cloud, few can clearly define what it will bring. The core characteristics of the cloud are already present in many aspects of our lives. Any gaps or unmet needs represent areas where cloud technology still has room to grow. One day, we may be able to handle all information seamlessly, regardless of time, location, platform, country, or vendor. When that happens, the true cloud era will arrive—but the journey is still long.
Back in 2010 and 2011, predictions about the bright future of cloud computing made headlines. Analysts claimed that cloud computing would be one of the most significant technological advancements since the invention of the computer. Opinions on market trends varied widely, but one thing was clear: the cloud was on the rise.
In recent years, cloud computing has become an unavoidable force. For many businesses, it’s now the standard for deploying new applications and services. As we look ahead, several key trends have emerged, some of which were predicted years ago—some were spot-on, while others turned out to be off the mark.
One of the early predictions was that cloud computing spending would grow rapidly. In 2012, Forrester estimated that public cloud spending would reach $159.3 billion by 2020. However, this prediction was actually too conservative. Since then, the growth has exceeded expectations, with Forrester revising its forecast upwards. By 2016, it predicted that public cloud revenue would hit $236 billion by 2020 due to faster-than-expected adoption.
Gartner also released a report in October 2017, stating that public cloud service revenue reached $219.6 billion in 2016 and could surpass $260.2 billion in 2017. Clearly, the cloud market is growing at a pace few anticipated.
Another prediction was that non-IT companies would enter the cloud market and become major players. Some analysts even suggested that big retailers like Best Buy might offer cloud services. However, this didn’t materialize. Instead, tech giants like Amazon, Microsoft, IBM, Google, and Alibaba dominate the space. According to Synergy Research, AWS holds more than a third of the public IaaS and PaaS markets.
There was also a belief that private clouds would be more popular than public ones. Early reports suggested that a quarter of IT resources would be managed through private clouds. While enterprises did invest heavily in private clouds, the trend has slowed, and public cloud adoption has surged. RightScale’s 2017 report found that 41% of organizations use public clouds, compared to 38% using private ones. This suggests that while private clouds remain relevant, public clouds are becoming the preferred choice.
Some analysts also predicted that people would stop buying computers altogether, as cloud services and smartphones became the main access points. While mobile internet traffic has indeed surpassed desktop traffic, PC sales haven’t disappeared. In fact, they’ve declined but not vanished, showing that personal computers still have a place in the digital world.
Another prediction was that tablets and thin clients would take over from traditional PCs. While tablets saw initial success, their popularity has waned. Thin clients also failed to gain widespread traction, especially as PCs became more affordable. However, some companies, particularly those using Google’s cloud services, have adopted Chromebooks.
The idea of “sky computing†was another early concept, suggesting a network of interconnected clouds. Although the term never caught on, hybrid and multi-cloud environments have become common, bringing together different cloud providers.
Open source was also seen as a key driver in cloud computing. OpenStack, Linux, and open-source databases have played a major role in shaping cloud infrastructure. Today, 82% of companies either use or plan to use OpenStack, highlighting its importance.
Looking ahead, the future of cloud computing is likely to be based on hybrid models. Companies are moving toward a mix of public, private, and hybrid clouds, leading to the rise of multi-cloud strategies. This approach allows businesses to leverage different cloud providers and avoid vendor lock-in.
Despite the rapid growth, challenges remain. Many companies are moving applications back to on-premises environments due to security and cost concerns. Latency issues also make private clouds a better fit for certain industries, such as IoT and edge computing.
While some believe the future will be dominated by public clouds, experts like Tim Crawford argue that hybrid and multi-cloud approaches are more realistic. He emphasizes that no single solution fits all, and most companies will need to combine different cloud models.
In conclusion, the cloud is evolving, but it’s far from being a one-size-fits-all solution. As technologies continue to develop, the future of cloud computing will likely be shaped by a combination of public, private, and hybrid models, along with a growing emphasis on open source and multi-cloud strategies.
