#Citrix transfers #Xen to the #Linux Foundation – via @scottjcutter

In 2007 Citrix acquired XenSource gaining control over the development of the Xen Hypervisor part of the Xen project. Today Citrix announcedthat it will hand over the Xen Project to the Linux Foundation which will continue its development. After both Ian Pratt and Simon Crosby who came from XenSource left Citrix to start their company Bromium, Citrix has clearly been struggling on how to continue its involvement in the development of the Xen project, leading to this decision.

The following companies will contribute to and guide the Xen Project as founding members of the Collaborative Project at The Linux Foundation: Amazon Web Services, AMD, Bromium, Calxeda, CA Technologies, Cisco, Citrix, Google, Intel, Oracle, Samsung and Verizon.

Its interesting to note that the Linux Foundation also supports the Kernel-based Virtual Machine (KVM) development, the hypervisor included in…

#Windows #Azure Virtual Machines and Virtual Network now are generally available

As I use to write; THIS IS INTERESTING! I think that Microsoft will take some market share for sure with their cloud service offerings!

Windows Azure Virtual Machines and Virtual Network now are generally available. We have new prices for Virtual Machines, Virtual Network, and Cloud Services.

Today is a major milestone for Windows Azure and all of our customers and partners. We are excited to announce that Windows Azure Virtual Machines and Windows Azure Virtual Network now are generally available. We also want to update you on new prices for Virtual Machines, Virtual Network, and Cloud Services.

Virtual Machines and Virtual Network help you meet changing business needs by providing on-demand, scalable infrastructure. These infrastructure services enable you to extend your data centers and workloads into the cloud while using your existing skills and investments. With these services, you can:

  • Provision Microsoft SharePoint farms in minutes without up-front hardware investments. Integrate full-trust code to run rich apps and provide Internet-facing collaboration sites.
  • Prototype your newest app or extend data marts into the cloud using Virtual Machines as a robust infrastructure for Microsoft SQL Server software. Scale on demand and connect to your on-premises infrastructure using Virtual Network.
  • Embrace rapid innovation using the cloud for development and test scenarios. You can spin up any test lab or sandbox quickly, and be agile in your learning, development, and prototyping.

Let’s take a closer look at the news that we are announcing today with general availability.

New high-memory instances for Virtual Machines

When your apps need more memory, new 28-gigabyte (GB) and 56-GB instances deliver.

Updated SLA

When you deploy multiple instances of Virtual Machines, Microsoft provides a financially backed 99.95 percent monthly service level agreement (SLA).

Customer support

Our customer support team is ready and available to help you troubleshoot 24 hours a day, seven days a week. We have several support plans tailored to meet your needs—from basic developer support to Premier Support.

What’s new in SCCM 2012 SP1 – update

September 14, 2012 1 comment

In my last post around SCCM 2012 SP1 (yes I know that I’m not supposed to use that abbreviation but I’m still gonna do it!) I forgot to look at and mention another important feature I must say…

OS X support!!!

This is really interesting, I bet that there are so many companies and architects out there sitting with X amount of different MDM and MAM solutions just to fit their needs around device and application management. But there are few out there that are covering all the OS’s and device types in a good manner.

Is SCCM going to try and tackle this at least for the MS, Linux, UNIX and OS X devices? And will they succeed all the way, don’t think so short term but long term perhaps. So now we architects have something to look forward to when planning our wanted position in this area and start evaluating the options for the roadmap towards it!

Client Deployment

The following items are new or have changed for client deployment in Configuration Manager SP1:

SCCM 2012 for Linux and UNIX

September 11, 2012 1 comment

Ok, this is interesting! Microsoft is adding more support for Configuration Manager in terms of managing Linux and UNIX targets. It will be interesting to see what the end-result will be when SP1 ships and most interesting will be if Microsoft will be able to convince the Linux and UNIX community out there that this is something that is competitive with other solutions like Puppet, Chef, STAF etc.

Here is a summary of the feature set planned for the SP1 release;

Functionality More information
Collections, queries, and maintenance windows Collections of Linux and UNIX Servers
Hardware inventory Hardware Inventory for Linux and UNIX Servers
Software Distribution Software Deployment to Linux and UNIX Servers
Monitoring and reporting Monitoring the Configuration of Linux and UNIX Servers
