In the past decade, organizations have aggressively overhauled their IT infrastructure to ensure that they are prepared to handle the more advantageous trends taking shape as time goes on, including mobility and big data. Although many firms were first somewhat one-dimensional in their approaches to cloud computing, more companies are now beginning to leverage public cloud and hybrid models that help to carefully align the investments with specific needs.
Hybrid IT infrastructure can be more affordable, secure and effective than only having a public or private cloud in place. As each business varies significantly across its departments and needs, its objectives vary as well – making a hybrid IT option a viable solution.
The World Bank cited mobility as having a major impact on the ways in which companies form their IT infrastructure, noting that there were nearly 7 billion cellular subscriptions last year and this figure is rising quickly. An estimated 40.7 percent of the global population attained Internet access last year, which is a major improvement from even five years ago. As cloud services evolve, the public cloud forecast looks to increase in affordable storage volumes.
The public cloud has been experiencing exponential growth for years now, making some experts wonder when a plateau of sorts will be reached. There are no signs that the market is going to stop expanding any time soon, as there has been a combination of companies just beginning to invest in the technology with long-term users working to expand out their capabilities in this area.
International Data Corporation recently predicted that global cloud infrastructure spending will expand by 24 percent in 2015 compared to last year, and the public model will play a major role in this. This includes several market segments grouped under the broader concept of cloud infrastructure, including networks, Ethernet switches, storage, servers and more.
According to the analysis, overall IT infrastructure spending will be up, but cloud-related investments are outpacing on-premise and other types of purchases, with an estimated one-third of spending on these needs being devoted to public and private models. Comparing this to 2014, the analysts stated that the percentage of IT infrastructure investments devoted to the cloud was at about 27.9 percent last year, and will surpass 33 percent in 2015.
Public cloud services were found to have a stronger compound annual growth rate than private ones, at 16.3 percent and 13.2 percent, respectively.
"Numerous IDC surveys indicate growing interest among enterprise customers to cloud deployments across multiple IT domains," IDC Research Director for Storage Systems Natalya Yezhkova explained. "End users often cite the agility of IT infrastructure and economic reasons as drivers for cloud adoption, but we also expect that the proliferation of next generation applications born and run in the cloud will fuel its further growth."
IDC believes that public cloud spending will increase by nearly 30 percent this year and reach a total market size of $20.5 billion globally. By 2019, the researchers expect total global cloud-based IT infrastructure spending to surpass $53 billion.
Impact on general corporate IT
Public models are proving to be more popular for several reasons, including the fact that the systems will be largely maintained and managed by third-party vendors.
As mentioned above, new trends are surfacing and intensifying relatively quickly today, and having IT professionals bogged down with routine maintenance requirements will hold the company back from seamlessly and intelligently getting relevant programs off of the ground. From the Internet of Things and big data to mobility and beyond, allowing technology workers to work on strategic matters will be endlessly beneficial to the business at large.
The hybrid approach has opened the gates for a wider range of companies, as so many were too concerned about security in wholly public models to leverage the solutions. In the coming years, more organizations are expected to embrace hybrid IT with the help of managed service providers.
