How CIOs Migrate their IT Applications to the Cloud

As the role of cloud computing is growing around the globe, many CIOs and other senior IT decision makers are facing challenges with their existing network infrastructure -- to support the migration of their business applications to the cloud. A new international study by Cisco Systems revealed the ongoing challenges associated with public or private cloud deployments.

These latest research findings provide insight into the current state of cloud service adoption and the chasm between IT expectations and network realities. The survey also examines the experiences of IT professionals regarding the level of difficulty and time required to update their networks and migrate their applications to the cloud.

The 2012 Cisco Global Cloud Networking Survey addresses the applications that are most critical for businesses to move to a cloud services delivery model, as well as the network challenges and potential disruptions and road blocks they are facing during this process. The report also takes a closer look at the typical length of these cloud migrations, and how confident IT professionals are in the ability of their own network deployments to securely deliver an optimal cloud application experience.

Among its findings, the study reveals that updating the network is one of the top focus areas for cloud migration. In order to successfully move more applications to the cloud, the majority of respondents cited a cloud-ready network (37 percent) as the biggest infrastructure element required for further cloud deployments, ahead of a virtualized data center (28 percent) or a service-level agreement from a managed cloud service provider (21 percent).

This data expands on the Cisco Global Cloud Index, which predicts that more than 50 percent of computing workloads in data centers will be cloud-based by 2014, and that global cloud traffic will grow over 12 times by 2015, to 1.6 zettabytes per year – the equivalent of over four days of business-class video for every person on Earth.

Key findings from the global market study include:

Cloud Deployments in Perspective

• Almost two in five (39 percent) of those surveyed said they dread network challenges associated with private or public cloud deployments so much that they would rather get a root canal, dig a ditch, or do their own taxes.
• At the same time, nearly three quarters (73 percent) feel they are confident with enough information to begin their private or public cloud deployments. However, the remainder (27 percent) feels they have more knowledge about how to play Angry Birds than the steps needed to migrate their company's network and applications to the cloud.
• In a clear sign that many IT organizations are still considering and planning cloud migrations, nearly one quarter (24 percent) of IT decision makers said that over the next six months, they are more likely to see a UFO, a unicorn or a ghost before they see their company's cloud migration starting and finishing.
• Without proper processes and planning, more than one quarter (31 percent) said they could train for a marathon in a shorter period of time than it would take to migrate their company's applications to the cloud.
• A majority (76 percent) predict their cloud applications are likely to be breached, yet only one quarter (24 percent) are confident to the point in which they believe the odds are better for them to be struck by lightning than have their cloud applications breached by an unwanted third party.

Cloud Deployments Expected to Increase Significantly by the end of 2012

• Presently, only 5 percent of IT decision makers have been able to migrate at least half of their total applications to the cloud. By the end of 2012, that number is expected to significantly rise, as one in five (20 percent) will have deployed over half of their total applications to the cloud.

Most Critical Infrastructure for Cloud Deployments

• In order to successfully move more applications to the cloud, the majority of respondents cited a cloud-ready network (37 percent) as the biggest infrastructure element required for further cloud deployments, ahead of a virtualized data center (28 percent) or a service-level agreement from a cloud service provider (21 percent).

Top Infrastructure Roadblocks to Cloud Migration

• During the cloud migration process, data protection security (72 percent) was cited as the top network challenge or roadblock responsible for preventing a successful implementation of cloud services, followed by availability/reliability of cloud applications (67 percent), device-based security (66 percent), visibility and control of applications across the WAN (60 percent) and overall application performance (60 percent).

Top Choice of Application for Cloud Migration

• If given the choice of only being able to move one application to the cloud, most respondents would choose storage (25 percent), followed by enterprise resource planning (ERP) applications to manage HR, customer relationship management, supply chain management, and project management systems (20 percent). Email (16 percent) and collaboration solutions (15 percent) followed.

Reality Check: Status of Cloud Application Migration

• When asked which applications have been moved, or are being planning to be moved to public or private clouds in the next year, the majority of IT decision makers cited email and Web services (77 percent), followed by storage (74 percent) and collaboration solutions such as Web conferencing and instant messaging (72 percent).

Global Cloud Index: the Evolution of Data Center Traffic

As 2011 comes to a close, many busy executives and IT managers will be pondering the continued adoption of cloud applications within their organizations. How can a business be adequately prepared for the anticipated increase in demand for managed cloud services? Moreover, what are the key related market indicators that are shaping the future of emerging business technology deployments?

The Cisco Global Cloud Index is an ongoing effort to forecast the growth of global data center and cloud-based IP traffic. The forecast includes trends associated with data center virtualization and cloud computing.

From 2000 to 2008, peer-to-peer file sharing dominated Internet traffic. As a result, the majority of Internet traffic did not touch a data center, but was communicated directly between Internet users. Since 2008, most Internet traffic has originated or terminated in a data center.

Data center traffic will continue to dominate Internet traffic for the foreseeable future, but the nature of data center traffic will undergo a fundamental transformation brought about by cloud applications, services, and infrastructure.

By 2015, one-third of data center traffic will be cloud traffic.

Global Data Center IP Traffic: Already in the Zettabyte Era

The Internet may not reach the zettabyte era until 2015, but the data center has already entered the zettabyte era. While the amount of traffic crossing the Internet and IP WAN networks is projected to reach nearly 1 zettabyte per year in 2015, the amount of data center traffic is already over 1 zettabyte per year -- and by 2015 will quadruple to reach 4.8 zettabytes per year.

This represents a 33 percent CAGR. The higher volume of data center traffic is due to the inclusion of traffic inside the data center (Typically, definitions of Internet and WAN stop at the boundary of the data center).

The global data center traffic forecast, a major component of the Global Cloud Index, covers network data centers worldwide operated by service providers as well as private enterprises.

Traffic Destinations: Most Traffic Stays Within the Data Center

In 2010, 77 percent of traffic remains within the data center, and this will decline only slightly to 76 percent by 2015. The fact that the majority of traffic remains within the data center can be attributed to several factors:

• Functional separation of application servers and storage, which requires all replication and backup traffic to traverse the data center.
• Functional separation of database and application servers, such that traffic is generated whenever an application reads from or writes to a central database.
• Parallel processing, which divides tasks into multiple smaller tasks and sends them to multiple servers, contributing to internal data center traffic.

The ratio of traffic exiting the data center to traffic remaining within the data center might be expected to increase over time, because video files are bandwidth-heavy and do not require database or processing traffic commensurate with their file size.

However, the ongoing virtualization of data centers offsets this trend. Virtualization of storage, for example, increases traffic within the data center because virtualized storage is no longer local to a rack or server.
