The worldwide total amount of electronic data has increased exponentially in the past few years. In fact, the sum of the world's extant data has grown such that we now measure the total number in Zetabytes (ZB). A single ZB is one billion terabytes. In 2009 the collected data of the human species was 0.8ZB. By 2015, that number is expected to have reached ten times that size, 8ZB. And by 2020, analysts expect the number to have grown to 35ZB. That's 44 times the volume of data that we had 11 years prior, in 2009.
It is also estimated that by 2020, more than one third of the data produced worldwide will live in or pass through the cloud. ASEAN-based enterprises are not exempted from this trend, estimating that their data growth is at a staggering 20-50 percent year-on-year. Some 17 percent even say that this growth is over 50 percent.
Rapid changes in the technology we use to store, access and directing data in an effective way has become critical for organizations who want to stay competitive without suffering from runaway storage costs.
Organizations are looking to virtualization and towards leveraging cloud services for both compute and storage, as a way to mitigate costs while maintaining availability and data integrity. Yet, while virtualization can eliminate the complexity and cost of physical infrastructure deployment, storing data in virtual machines and within the cloud could jeopardize data security.
Cloud and virtualization
A growing number of enterprises are consolidating their IT infrastructures to private and public clouds. In fact, Gartner forecasts public cloud services to grow to $137 billion with a CAGR of 16.9 percent by 2017, while private cloud capacity is expected to outpace global storage capacity by 1.5 times (60 percent to 40 percent).
The mitigating factors in cloud adoption are the costs and complexity involved in managing the hardware and the people resources needed to control the explosion of data - which is still overwhelming running on legacy infrastructures.
Virtualization is a game changer for organizations adopting a cloud as a platform and/or as a storage environment. The benefits of server virtualization are compelling from cost savings through business flexibility, and the agility inherent in emergent private and public cloud architectures. Yet, according to a global study, nearly nine out of 10 IT managers believe virtual machine (VM) management is risky without proper planning. Indeed, the ease of deploying new VMs can lead to a virtual machine sprawl, making it tedious and time consuming for administrators to keep track of new virtual machines and to ensure data protection and retention policies are applied to them.
