The Importance of Data Connectivity to Virtualization

Don't let inefficient data access undermine your virtualization goals

Data center architects naturally seek to employ server virtualization to maximize the use of their hardware systems. However, one factor – often overlooked – carries real potential to undermine this goal. That factor is data connectivity. This article examines the importance of data connectivity in a virtualized environment, and the need to take an intelligent approach to data access to truly reap the benefits of your virtualization strategy.

As strides have been made over the years in database optimization and the performance of processors and other hardware-based server components, the performance bottleneck has moved to the database middleware – the software drivers that provide connectivity between applications and databases. Between 75% to 95% of the response time now associated with database access can often be attributed to the data connectivity layer – and that’s using traditional non-virtualized servers. Running multiple virtual servers on a single machine can introduce additional complications involving data access.

Old Problems Become New Again
Exponential improvements in processor speed and design, continual strides in network capacity, and commoditized memory together promised to make hardware resource contention a thing of the past. However, with new capacity come new applications and new uses for information technology. In reality, the demand for applications is actually outstripping the ability of hardware improvements to accommodate them. That’s one reason why the number of x86 servers is projected to grow – according to IT research firm IDC – 39% by 2010 (adjusted down from an initially projected 61% due to the expected impact of server virtualization).

Consider this trend in light of the value proposition presented by virtualization technology: that you can use software to run multiple virtual machines (VMs) on the same single physical machine formerly employed as a dedicated server. Now multiple operating systems and their attendant applications must vie for the same discrete resources such as processor capacity, memory, storage I/O, and network I/O. The dormant issues of resource contention arise once again. Naturally, anyone considering a virtualized server environment must plan for sufficient hardware-based resource capacity to accommodate it. But adding additional capacity is not always feasible — flexibility in expanding network I/O, for instance, is something available only on relatively high-end machines.

Microservices Articles
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
"NetApp's vision is how we help organizations manage data - delivering the right data in the right place, in the right time, to the people who need it, and doing it agnostic to what the platform is," explained Josh Atwell, Developer Advocate for NetApp, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...
In his session at 20th Cloud Expo, Mike Johnston, an infrastructure engineer at Supergiant.io, discussed how to use Kubernetes to set up a SaaS infrastructure for your business. Mike Johnston is an infrastructure engineer at Supergiant.io with over 12 years of experience designing, deploying, and maintaining server and workstation infrastructure at all scales. He has experience with brick and mortar data centers as well as cloud providers like Digital Ocean, Amazon Web Services, and Rackspace. H...
Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, will discuss why containers should be paired with new architectural practices such as microservices ra...
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one. In his session at 16th Cloud Expo, Reuven Harrison, CTO and Co-Founder of Tufin, ...
DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...
Many organizations are now looking to DevOps maturity models to gauge their DevOps adoption and compare their maturity to their peers. However, as enterprise organizations rush to adopt DevOps, moving past experimentation to embrace it at scale, they are in danger of falling into the trap that they have fallen into time and time again. Unfortunately, we've seen this movie before, and we know how it ends: badly.
TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and...
