SAML to the Rescue: vCenter Single Sign On

VirtualizationSecurityVMware vCenter 5.1 implemented a new security feature, Single Sign-On (SSO), that uses the Security Assertion Markup Language (SAML) to exchange security tokens. This combats an extremely well-known and prevalent attack within the virtualization management trust zones: SSL Man-in-the-Middle (MiTM) attacks. However, vCenter still supports the old SSL methods as well to maintain backwards compatibility and to allow management when SSO is not in use. Does this new feature change how we look at virtualization and cloud management security best practices? Is it a launch point for implementing other authentication techniques?

APM as a Service and CA’s Reaction

BlindDinosaurLegacy management software vendors like IBM, HP, BMC and CA are in deep trouble. They are in trouble across their entire portfolio of management solutions due to two simple facts. Their products are not suited for the new dynamic and distributed IT environment, and the way in which they sell and market those products is inconsistent with how the new buyers of management software want to buy those products. A great example of the trouble that legacy vendors are in is how CA and its APM solutions (Introscope) stack up against modern solutions like those from New Relic, AppDynamics, and Compuware/dynatrace.

Windows 2012 Hyper-V – the hypervisor for your Cloud? Part II

DataCenterVirtualizationWindows 2012 Hyper-V is the hypervisor for the cloud, VMware’s vSphere is a dead man walking?

In Part I I shared a chunk of what I learned from Aidan Finn‘s enlightening and entertaining session delivered at the E2E Virtulisation Conference in Hamburg tastefully titled, “Windows Server 2012 Hyper-V & VSphere 5.1 – Death Match”. In Part I we looked at pricing, scalability and performance, as well as storage in questioning how bold this statement was.

Pure license-cost wise, it more straightforward to run Microsoft Hyper-V than add another licensed hypervisor: note that Hyper-V does have a free offering (although this version doesn’t cover the virtual Windows Server instance licenses). We showed that scalability wise, Hyper-V can better common competition. Storage-wise Hyper-V, as should be expected from the newest offering, supports the newest technology: 4k sector sizes, and had the largest virtual disk support. Still, if you needed greater than 2TB of storage, you could always join multiple 2TB instances together, or bypass limits by mapping a LUN direct to the VM.

Still, besides pricing simplicity, performance improvements, and updated storage what has Microsoft done for the latest version of Hyper-V? In Part II, lets question further Aidan’s premise that Hyper-V kills vSphere.

Cisco Acquires Cloupia – Becoming a Management Software Vendor?

VirtualizationManagementIconOn November 15th, Cisco announced that it was acquiring Cloupia a cloud management startup that had built a unique combination of physical provisioning for converged infrastructures like the Cisco UCS and its downstream partner bundles like vBlocks and NetApp Flexpods with the ability to automate the provisioning of IaaS clouds on these converged infrastructures. Cisco had previously acquired Tidal Software, a vendor specializing in monitoring SAP in production, and newScale, a vendor who arguably lead the market for enterprise grade service catalogs.

A Secure Cloud Framework for Non-Clouds

DataCenterVirtualizationIs it possible to use a cloud framework to better secure your datacenter? Do cloud technologies provide a secure framework for building more than just clouds? We all know that virtualization is a building block to the cloud, but there may be a way to use cloud frameworks to first secure your datacenter before you launch a private, public, or hybrid cloud. In essence, we can use tools like vCloud Director to provide a more secure environment that properly segregates trust zones from one another while allowing specific accesses.

Waratek – forget VMware, just virtualize the JVM

Agile Cloud DevelopmentWaratek is a one-off company with a disruptive technology (remember VMware was like this once) that forces you to reset your undertanding of how things could work.  Waratek’s big idea is that you virtualize as high up the stack as you can because that gives you the best benefit in terms of sharing infrastructure. So rather than replicating operating systems on a hypervisor accessing shared hardware, you simply replicate as small a part as possible of the Java Virtual Machine (JVM).  Everything else (hardware, operating system and most of the JVM) is shared.
