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.

Public and Private Clouds for the Enterprise

Telecommunication service providers will likely consume their own cloud services. After all, every organization can gain something from the proven benefits of infrastructure and application out-tasking. However, their primary role will be to implement and deliver the services that their end-customers will seek from public, virtual private, and hybrid clouds.

Service providers have the opportunity to extend their current offerings, which may already include hosting, communications, media, and software application services. Moreover, cloud offerings enable service providers to extend their reach beyond their traditional areas of operation.

That said, service providers must be prepared to address customer concerns ranging from policy compliance, to end-to-end security, to quality of service management, and to technical customization. They must be able to deliver a flexible range of functionality, service levels, and payment models.

Enterprise Cloud Use-Case Scenario

• Many enterprise-focused service providers (SPs) have an opportunity to create higher-value, differentiated service offerings. They have unique capabilities they can leverage, including customer relationships, physical assets, and extensive operations experience.
• At the same time, over-the-top services (such as Skype VoIP) threaten traditional SP revenue streams (e.g., wireline and mobile voice services). So, SPs have an incentive to evolve their value-add capabilities.

Role for Cloud Technologies

• Cloud is unlocking huge growth potential through new service offerings (e.g., infrastructure as a service, collaboration as a service).
• SPs offering cloud services have several avenues of differentiation in terms of deployment models (e.g., public cloud, virtual private cloud, hybrid cloud) and service types (e.g., infrastructure, collaboration).
• A cloud-ready architecture can also reduce an SP’s overall cost of delivery through more efficient and sustainable infrastructure platforms.

Application Considerations

• As table-stakes, SPs offering cloud services must ensure security and isolation of customer data in a multi-tenant environment. They must also offer a comprehensive suite of basic services (e.g., voice, collaboration).
• Initial customer acquisition will be driven by distinctive solutions with differentiated services and end-to-end service level agreements (SLAs).
• Over the long term, SPs must be able to deliver cost-effective services with viable margins.

While large enterprises also see tangible benefits in using public clouds, we expect private and hybrid cloud models to be very common. Large enterprises may use public clouds for burst or peak capacity and for select services that are difficult to scale themselves.

However, these organizations often require a higher degree of control over their data, applications, and systems than current public clouds allow. At scale, a private cloud offers the efficiency and agility of a public cloud -- without the loss of control.

Still, the IT services that a pure private cloud can offer are often limited to what internal IT can develop or deploy. This is where managed cloud service providers can add value.

How to Unlock the Power of Virtualization

Virtualization uses technology to remove the physical barriers associated with computer servers and applications -- enabling the consolidation or replacement of servers, storage, network and other physical devices.

As a result, your business can better use computing capacity and drive more value from IT resources as well as consolidate data centers and significantly lower energy consumption.

For companies who need guidance on a virtualization project, Verizon Business offers these five tips -- culled from the company's years of experience handling complex IT installations and expertise in implementing and managing virtual environments:

1. Make sure you're looking at the big picture: A business should first complete a thorough assessment of its current IT environment and computing resources, including a full review of all servers. Once the enterprise has a better understanding of its infrastructure, it is easier to determine which computing resources, such as servers and devices, are candidates for consolidation.
2. Enlist vendor support: After compiling a list of applications that can be virtualized, it is important to confirm there will be very few, if any, issues with vendor support. Some vendors, especially smaller ones, do not support their software on virtualized platforms.
3. Evaluate licensing costs: When assessing applications for migration, evaluate the licensing costs associated with them. While consolidating multiple servers and devices into a single virtual machine will lower hardware and facility costs, this does not necessarily apply to software licensing costs. Many vendors still charge based on total available power and the number of physical applications. If that's the case, consider working with vendors that embrace more flexible licensing models.
4. Avoid common bottlenecks: Carefully assess the memory and storage requirements for applications moving to the virtual environment. Memory and storage can severely limit how many virtual machines a host can support. A common scenario is an environment with consolidated storage and a high number of mobile BlackBerry users, requiring large memory and storage needs. Therefore, assessment, management and proper allocation of applications per virtual machine are key.
5. Security, security, security: Security should be a top priority; it should be built in from the ground up to ensure the new environment comes with the right safeguards. Enterprises also should pay close attention to relevant industry regulations. For instance, businesses that store, handle or process customer payment information must maintain compliance with the Payment Card Industry Data Security Standard (PCI DSS), a comprehensive set of requirements for enhancing payment account data security. In that case, PCI DSS compliance would be a key requirement for the new virtual environment.
   

"Virtualization holds huge promise for the enterprise," said Michael Marcellin, vice president of Verizon global managed solutions. "Its ability to increase efficiency and agility while managing costs is unparalleled. With that potential, however, comes complexity concerning deployment and implementation. Our hope is that enterprises will take this promising technology to heart and embrace our suggestions -- based on our more than 10 years experience managing complex IT infrastructures -- on how best to utilize it."

Verizon Business offers a wealth of IT and hosting solutions to help customers meet their most-pressing IT needs in today's dynamic business environment. As we've previously reported on the Business Technology Roundtable, enterprise and small-business executives are actively adopting the selective out-tasking of applications to these managed cloud services.
