Virtual desktop infrastructure (VDI) and related end-user computing capabilities are most definitely not dead. In fact, I think the technologies are finally starting to support practical and cost-effective implementations for every size business. VMware Horizon and Mirage likely have some hot things going, and it’s always interesting to see how PCoIP has evolved.

TAKE 2 Designing Your Next-Generation Datacenter for Network Virtualization (NET5184)

Can you spell VXLAN? If you come away from VMworld 2013 with a good understanding of software-defined networking (SDN) and network virtualization, you could be the geek hero of your IT shop.

Converged Infrastructure, or ‘Where Did All the Silos Go?’

An IT industry analyst article published by Virtualization Review.

Quite a few companies are mashing up server, storage, networking and even the hypervisor into turnkey solutions that can scale up or down as data center needs dictate.

article_converged-infrastructureOnce upon a time as IT shops grew and matured, infrastructure subgroups would form to focus on complex domain-specific technologies. Servers, storage and networking all required deep subject matter expertise and a single-minded focus to keep up with the varying intricacies of implementation, operations and management. In large enterprises, fully staffed silos working in concert could leverage mountains of technology to great effect. But inevitably, turf battles, budget tightening and the fact that smaller organizations might not reach critical mass can make the silo approach costly and inefficient.

Virtualization solutions at first helped the silo model by abstracting the user of idealized IT from its physical implementation. Increasingly independent silos of underlying infrastructure could then be designed and managed very differently, and hopefully optimally, from what the end client sees. And in fact, virtualization became its own new IT domain, adding yet another layer of IT silo complexity.

But here at Taneja Group, we’ve noted several trends that are coming together to break down the traditional IT silo model. The virtual admin originally in charge of the hypervisor and server cluster is now on the verge of subsuming storage and networking too. New generations of “software defined” and cloud-provisionable technologies enable virtual admins to dynamically allocate increasingly enterprise-class resources to clients. And on the infrastructure side, converged infrastructure solutions make the physical implementation as simple as snapping Lego-like building blocks together.

For a while there have been bundled solutions that pre-package infrastructure into nice racks. Buying IT in pallets can be attractive in many growth or transformation scenarios, but at the end of the day they are still composed of racks of traditional enterprise infrastructure. In most cases, these solutions are adopted by customers that probably have the silo expertise to build their own, but are looking for a cost-effective shortcut.

What we are really excited about are the new “hyper-converged” infrastructure solutions that are designed from the ground up as scale-out units of IT. Server, storage, networking, and even the hypervisor may have been integrated as a single racked unit. Deployment and growth are simply handled by racking and stacking more identical (or similar as needed) units. They plug together and re-pool storage, cluster the servers and share key resources like flash. IT no longer needs deep silo staffing to deploy and operate enterprise quality solutions.

Is Virtualization Stalled On Performance?

An IT industry analyst article published by Virtualization Review.

Virtualization and cloud architectures are driving great efficiency and agility gains across wide swaths of the data center, but they can also make it harder to deliver consistent performance to critical applications. Let’s look at some solutions.

article_virtualization-stalled-performanceOne of the hardest challenges for an IT provider today is to guarantee a specific level of “response-time” performance to applications. Performance is absolutely mission-critical for many business applications, which has often led to expensively over-provisioned and dedicated infrastructures. Unfortunately broad technology evolutions like virtualization and cloud architectures that are driving great efficiency and agility gains across wide swaths of the data center can actually make it harder to deliver consistent performance to critical applications.

For example, solutions like VMware vSphere and Microsoft Hyper-V have been a godsend to overflowing data centers full of under-utilized servers by enabling such high levels of consolidation that it has saved companies, empowered new paradigms (i.e. cloud), and positively impacted our environment. Yet large virtualization projects tend to stall when it comes time to host performance-sensitive applications. Currently, the dynamic infrastructures of these x86 server virtualization technologies don’t provide a simple way for applications to allocate a “real performance level” in the same manner as they easily allocate a given capacity of virtual resource (e.g. CPU, disk space). In addition, virtualization solutions can introduce extra challenges by hiding resource contention, sharing resources dynamically, and optimizing for greatest utilization.

The good news is that additional performance management can help IT virtualize applications that require guaranteed performance, identify when performance gets out of whack, and rapidly uncover where contention and bottlenecks might be hiding
