Licensing: Pools and Architecture Changes?

In the past, virtualization architects and administrators were told the best way forward is to buy as much fast memory as they could afford as well as standardize on one set of boxes with as many CPUs as they dare use. With vRAM Pool licensing this type of open-ended RAM architecture will change as now I have to consider vRAM pools when I architect new cloud and virtual environments. So let’s look at this from existing virtual environments and then onto new virtual and cloud environments. How much a change will this be to how I architect things today, and how much of a change is there to my existing virtual environments? Is it a better decision to stay at vSphere 4? Or to switch hypervisors entirely?

VDI Environments

Yesterday, Simon Bramfit vSphere 5 – Did VMware Misjudge its Licensing Changes? requested a VDI only version of vSphere and yesterday VMware responded with vSphere Desktop which for VDI removes the vRAM Entitlement barrier. I see this as progress and that VMware is listening. Unfortunately, this is for new purchases and you cannot convert existing vSphere licenses into vSphere Desktop licenses.

Where are my NOC Views: Virtualization Management Vendors

As a delegate for Tech Field Day 6 in Boston, I was introduced to many third party management tools. In the past I have been given briefings as well on various VMware, Hyper-V, and Citrix Xen Management Tools as well. Many of these tools are marketed directly for use by the administrator, but they have the tools can be used by more than the administrator. These tools should be marketed to management, administrators, as well as the network operations center (NOC). The NOC you say, why should they see the details of my environment? The NOC should not, but they should be able to tell when systems are in failure states outside of the hardware. Only a few tools can be used this way today. The sooner  administrators get the word of a problem the sooner it can be fixed. The NOC is the one place that centralizes all monitoring whether it is for security or health of your virtual and cloud environments.

Centralized RBAC Missing from Virtualization Management Tools

As a delegate for Tech Field Day 6 in Boston, I was introduced to several virtualization and performance management tools from vKernel, NetApp, Solarwinds, Embotics, and a company still in stealth mode. With all these tools and products I noticed that each was not integrated into the roles and permissions of the underlying hypervisor management servers such as VMware vCenter, Citrix XenConsole, or Microsoft System Center.  This lack of integration implies that a user with one set of authorizations just needs to switch tools to gain a greater or even lesser set of authorizations. This is not a good security posture and in fact could devolve any security to non-existent. Continue reading Centralized RBAC Missing from Virtualization Management Tools

A Perfect Storm in Availability and Performance Monitoring

Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.

SolarWinds Acquires Hyper9 – The Implications

The question of how to manage virtualized environments as they scale up in size and complexity, and grow to host business critical applications (instead of just low hanging fruit tactical applications owned by IT) is clearly starting to get attention by larger vendors with serious ambitions in the virtualization performance management market. NetApp is acquiring Akorri, putting NetApp into a leadership position in Infrastructure Performance Management. Now SolarWinds acquires Hyper9. Continue reading SolarWinds Acquires Hyper9 – The Implications

Reinventing Infrastructure Performance Monitoring for the Cloud

Virtualization (the underlying foundation of a cloud) introduces a set of challenges to how one should monitor the performance of the infrastructure and the applications. These challenges are:

  1. Unlike physical systems that are mostly dedicated to specific applications, virtual systems are both shared and dynamic. This makes inferring the performance of the infrastructure by looking at resource utilization statistics ineffective. Leading edge Infrastructure Performance Management vendors like AppFirst, Akorri, CA|NetQos, Virtual Instruments and Xangati are taking an Infrastructure Response Time approach to this problem that avoids the issues of relying upon resource metrics, and provides a true picture of how the infrastructure is actually performing.
