Understanding the risks & challenges of Emerging IT Technology

As we believe that IT Systems and Communication is on paradigm shift towards new trends because of cloud computing,NFV, SDN and IoT . Cloud computing is an evolving IT technology for the next generation infrastructure systems; obviously it becomes requirement for industries, business and organizations in near future.

In past days; the need of computer systems was being treated as the basic requirement for human being, just similar as the requirement of using water, gas, or electricity. To meet this everyday need for general community, cloud computing is the way out by having support of Wireless sensor networks and virtualization, we can develop easily a ubiquitous computing IoT networks for general public and communities to fulfill their basic needs smartly.

Accomplishing this, we have to deploy high performance virtual machines and devices to handle inter-connected systems workloads, Bigdata and BYOD challenges and to maintain the utmost security levels.

Not more than 2-3 years ago, industries were moving slowly over cloud due to having risk factor.

Following is a chart by IDG published in 2013;

But; today in 2016, with the latest developments in SDN and NFV technologies; world is accepting the cloud computing trends more curiously.Following is the study from cisco, indicating cisco global cloud index:

Cisco said it as “The Zettabyte Era,” where a zettabyte equals 1 trillion gigabytes. * CAGR stands for compound annual growth rate

According to Cisco Study on Data Center Virtualization and Cloud Computing Growth

●   By 2018, more than three quarters (78 percent) of workloads will be processed by cloud data centers; 22 percent will be processed by traditional data centers.

●   Overall data center workloads will nearly double (1.9-fold) from 2013 to 2018; however, cloud workloads will nearly triple (2.9-fold) over the same period.

●   The workload density (that is, workloads per physical server) for cloud data centers was 5.2 in 2013 and will grow to 7.5 by 2018. Comparatively, for traditional data centers, workload density was 2.2 in 2013 and will grow to 2.5 by 2018.

Public vs. Private Cloud

●   By 2018, 31 percent of the cloud workloads will be in public cloud data centers, up from 22 percent in 2013. (CAGR of 33 percent from 2013 to 2018).

●   By 2018, 69 percent of the cloud workloads will be in private cloud data centers, down from 78 percent in 2013. (CAGR of 21 percent from 2013 to 2018).

As Cloud computing have high potential in it to merge public and private clouds, we can make multi cloud or hybrid clouds provisioning with legacy applications. Cloud computing has potential to establish, scale and secure any new application or services. Furthermore, users can define their own composite clouds.

The big challenge is that IP Traffic will increase with the increasing factor of connectivity

Due to the increasing factor of BYOD and guest VMs, expected growth of IP traffic will grow at CAGR of 51 percent from 2012 to 2017.

Following is the chart by Cisco showing increasing factor of virtual network interfaces (VNI).

IP Traffic will increase with the increasing factor of connectivity

The risk factor over which data storage and transfer security issues remain somehow till 2014, is now going to be minimized after an association of Open API working groups, including CipherCloud and CSA, this consortium will deliver guideline on vendor-neutral data-security implementation to aid those industries which are still not moving on cloud services adoption.
