The Virtualization Practice
VirtualizationSecurity

Symantec and others are providing more products that fill the gaps in current End-to-End Hybrid Cloud Security. These solutions range to improved log analysis through multi-layer security for critical systems. If these solutions are rolled out would we finally have secure environments? Would we be approaching the dream of secure multi-tenancy? But first what are the products that have come to light?

Wanova100x30

VMware have announced the upcoming acquisition of Wanova. The combination of VMware View and Wanova Mirage will be an an industry first pairing that could well dramatically redefine the VDI market. It is increasingly common to find vendors acknowledging that a VDI-only solution is not enough. Citrix know it. Quest know it. Desktone know it. We’ve critiqued before that by having a VDI only view, VMware doesn’t “get” desktops. With their Wanova acquisition VMware gets desktops.

FlexAppArchi-149-90

Liquidware Labs ProfileUnity 5.0 with FlexApp offers an option for user-installed applications (UIA) technology. This new feature offers VDI users the option to seamlessly install their own applications into any non-persistent Windows environment without affecting master images or underlying systems. We take a look what FlexApp delivers, where it is headed and consider it in the context of Citrix Personal vDisks and AppSense StrataApps

How do we measure success? This seems like it should be an easy question to answer but is it? Success itself is a dynamic variable that can be defined in several different ways from a promotion or even recognition from your peers. Now what about a successful cloud implementation or implementation in general? How would you define success? The true definition of implementing is to fulfill; perform; carry out: or to put into effect according to or by means of a definite plan or procedure. For the design and implementation team, success could be defined by the completed installation design, deployment and verification testing of all functionality as defined in the statement of work.

PerformanceManagement

The IaaS Cloud Performance Management Problem will continue to be one of two major factors impeding the adoption of public cloud services (multi-tenant security being the other one). Inferring performance from resource utilization metrics does not work in a simple single tenant virtualized environment (vSphere in your data center). It is worse than useless in muti-tenant public cloud environments that are build up upon a virtualization platform. The only known fix for this issue is for the cloud vendors to embrace end-to-end infrastructure latency as the quality of service metric and to surface this metric on a per tenant and per image basis to their customers.

There is a class of applications that is extremely difficult to virtualize. This group consists of graphics intensive applications such as ProEngineer, Photoshop, and pretty much anything that requires a GPU to perform well. Graphics intensive applications make up a list of applications that are usually too big or expensive to virtualize. The last mile so to speak. This is NO longer the case. With NVIDIA’s announcement of the NVIDIA VGX Cloud Platform. This and other classes of applications can now be virtualized.

There seems to be a myriad of definitions of who is a tenant when it comes to secure multi-tenancy. This debate has occurred not only within The Virtualization Practice as well as at recent Interop and Symantec Vision conferences I attended. So who really is the tenant within a multi-tenant environment? It appears multiple definitions exist and if we cannot define Tenant, then how do you build secure applications that claim to be multi-tenant?

AppSense_Company_Logo_100x30

Much of the recent buzz around AppSense from AppSense Labs,the research division at AppSense that is responsible for StrataApps, DataLocker and DataNow, its hot new tools to support user installed applications and provide increased security in consumer cloud services. Nevertheless, AppSense has not forgotten its roots and has recently released a major update to its core user persona management platform UV Suite.
