The 3/22 Virtualization Security Podcast brought to light the capabilities of Symantec Critical System Protection (CSP) software. This software successfully implements a manageable version of mandatory access control policies based on role-based and multi-level security functionality within the virtual environment. More specifically on those systems that are critical to the well being and health of your virtual and cloud environments such as all your management and control-plane tools (VMware vCenter, Microsoft SCVVM, XenConsole, etc.). In addition, Symantec CSP will monitor your virtualization hosts for common security issues. This in itself is great news but why are we just hearing about this now? Is this a replacement for other security tools?
There are many different types of metrics pertaining to storage and IO that can be grouped into Performance, Availability, Capacity, Economics and Energy (PACE). Every application or workload has some characteristics attribute of Performance, Availability, Capacity, Economics and Energy that can be further broken down into metrics that are more detailed.
There has been a lot of buzz and coverage about Windows 8 since its consumer preview. There will be some very cool features with this release and one feature that really stands out with me is that Microsoft added an additional supported processor type in that Windows 8 will run on Intel, AMD and now ARM based processors. That gives Windows 8 the ability to run on desktops as well as mobile phones and tablets.
One of the areas where VMware vSphere has had a large advantage over Microsoft Hyper-V has been in the architecture and capabilities of the VMware vSphere Virtual Switch. The most important of these capabilities has been the ability to designate one or more ports on the switch as promiscuous or mirror ports. These ports make a read only copy of all of the data flowing through the switch available to whatever virtual machine is sitting on that port. This is an essential capability for many security products and also performance management solutions like those from ExtraHop Networks that rely upon deep packet inspection to work.

Virtualizing Presentation Virtualization Workloads is increasingly seen as beneficial and more acceptable. As Citrix XenApp customers move into 2013 it is likely they’ll move more physical instances to virtual. To enhance RDS VM workloads with shared storage – Atlantis release ILIO for XenApp, the first solution designed specifically to accelerate provisioning, boot time and application response time
Quantum recently announced a ‘Flexible path to Next Generation Backup and Disaster Recovery’, which dovetails nicely with my thoughts on future proofing data protection. Quantum has created, with the help of Xerox, a way to have multi-tenant data protection at the level of the tenant and not just the cloud provider.

There is no one APM tool, be it network based or application based that can meet the needs for every constituent and every application. The tool should be chosen based upon the needs of the team supporting the application(s) in question, and the type of applications that must be supported (purchased or custom developed, and if custom developed via what method). Virtualization plays a key role and that it is giving rise to new organizational function often called Application Operations which is responsible for the performance of all of the applications in production.
SSD options for Virtual (and Physical) Environments Part IV: What type of SSD is best for your needs.

Let us continue to look at what SSD to use for different environments and build off the other parts of this series of articles. Part 1 of this series laid out the basics of nand flash Solid State Devices (SSD) with part II discussing endurance and performance. Part III looked at SSD options for virtual servers, VDI or virtual desktop as well as storage for physical server environments, usage and configuration criteria. So which SSD options are best for which environments?
