Software-as-a-Service quickly became the most popular solution within the cloud computing market several years ago, especially as the tools were easy to access, affordable and capable of facilitating corporate email, file sharing and other critical functions. However, in the past two or three years, Infrastructure-as-a-Service and Platform-as-a-Service have become far more popular, especially because of the common need for customized apps and IT setups among organizations.

Businesses of all sizes are now migrating to IaaS cloud models to reduce expenditures related to equipment purchases and maintenance, while simultaneously bolstering the flexibility of IT. Enterprise-class cloud models have also started to gain a larger share of the market that was historically help by public options, and these trends are only expected to intensify in the coming years.

A flock toward IaaS cloud
Jamie Hinks, writing for ITProPortal, recently reported that a survey conducted by Riverbed Technology, which specializes in WAN optimization, found that roughly 80 percent of respondents have already used an IaaS cloud to facilitate the deployment of applications. Between enterprise mobility, big data and several other trends in corporate computing, applications have become a focal point for decision-makers.

With PaaS and IaaS, companies have an enhanced ability to develop and deliver customized apps to employees, customers, vendors and more. According to Hinks, fears related to IaaS cloud have been relatively consistent throughout the past several years, and include cost management, security capabilities and overall performance. However, IaaS cloud providers continue to innovate and offer businesses more reliable options.

The author noted that companies that are concerned about performance are mostly fearful of a lack of in-house expertise when it comes to IaaS management, but that this might be a fleeting issue considering the involvement of vendors in general maintenance and support.

Additionally, Hinks stated that companies should be careful when planning cloud investments and deployments, and that overly complex multi-vendor options might not be the best choice. 

How private clouds will evolve
InformationWeek recently released its latest Private Cloud Survey, which found that many respondents are planning to increase their organizational knowledge of the technology. For example, more than three-quarters of respondents stated that they had already invested in increased training content to improve IT departments' and other employees' expertise regarding private cloud management.

By working closely with the vendor of these services, decision-makers can quickly strike a preferable balance between cost management, performance controls and security.
