SDDC Application Performance Management

SDDC.Management.Stack.Reference.ArchitectureThe Software Defined Data Center (SDDC) will be a highly dynamic environment with constantly changing configuration and resource allocation settings driven by various forms of automation including the provisioning of workloads from service catalogs, the scaling of workloads in response to demand, and the migration of workloads across hosts for workload balancing and prioritization reasons. Due to Agile Development, applications are now changing more quickly than ever before. So we are going to have rapidly changing applications running on a rapidly changing software infrastructure. This will drive the need for SDDC Application Performance Management.

Cyber Defense: Using Virtual Desktops?

DesktopVirtualizationThere was recently a rather heated twitter discussion between @Guisebule, @VirtualTal, and @Texiwill (myself) about using virtual desktops as a part of cyber defense. While this could be true, there is a need to ensure you know where your virtual desktop(s) start and end, not only within the network, but your applications in use. In addition, it is very important to fully understand the scope of a virtual desktop architecture as well as use. There are some use cases that work very well for use of virtual desktops as a part of cyber defense or for that matter just make sense for virtual desktops. There two ways to make virtual desktops part of your cyber defense but they both require more than network security.

How Will VMware Win Against Microsoft?

DataCenterVirtualizationWhile VMware is still the undisputed leader in enterprise data center virtualization, it is also very obvious that Microsoft has made (and continues to make) significant inroads into both the broader data center virtualization market and into VMware’s own enterprise customer base. The general perception is that Microsoft Hyper-V is now “good enough” to run most production workloads, that it is close enough (or at parity) in functionality and performance to vSphere for customers to be able to move workloads from vSphere to Hyper-V, and that vSphere is “expensive” and Hyper-V is “free”. So how will VMware win against Microsoft? Continue reading How Will VMware Win Against Microsoft?

Host Deployments in a Software Defined Data Center (SDDC)

DataCenterVirtualizationHost deployments in a Software Defined Data Center (SDDC):  How do you deploy the hypervisors in your company?  There are several different choices: installing from a CD, installing over the network, and/or Pre eXecution Environment (PXE), to name a few methods currently available. When there are not too many physical hypervisors to worry about, CD installation works just fine; the need for automated installation grows in direct correlation to the number of hosts.

DataStax – Three Ways to access the same Big Data

CloudComputingWe recently had a conversation with DataStax regarding their DataStax Enterprise product, which got us to thinking a little about the nature of Big Data and Cloud.   DataStax is the company behind the Open Source Cassandra NoSQL database. It provides technical direction and the majority of committers to the Apache Cassandra project.  Cassandra in turn is a Column Family-based database along the lines of Google’s BigTable. If you are a SQL programmer it’s determining feature is… it doesn’t do joins. Continue reading DataStax – Three Ways to access the same Big Data

Virtual Desktop Patching and Data Protection

DesktopVirtualizationData Protection and patch management of virtual desktops, while not a sexy topic, is one that should happen on a regular basis within any organization  implementing or working to implement virtual desktops.  Recently, we have been testing virtual desktop software and there is a huge difference between patching and protecting data in a small number of instances and 1000s of instances. There are scale considerations as well as ease of use for file level and system recovery as well as issues with patching virtual desktops (not to mention other security issues).
