Hyper-V Containers bringing speed and scale to the next level in today’s cloud-first world

April 9, 2015 Leave a comment

Last October, Microsoft and Docker, Inc. jointly announced plans to bring containers to developers across the Docker and Windows ecosystems via Windows Server.

Hyper-V Containers will ensure code running in one container remains isolated and cannot impact the host operating system or other containers running on the same host. Applications developed for Windows Server Containers can be deployed as a Hyper-V Container without modification, providing greater flexibility for operators who need to choose degrees of density, agility, and isolation in a multi-platform, multi-application environment.

Docker

The new Microsoft Container technology offers flexibility and choice through Windows Server containers, Linux containers, and Hyper-V containers both in the cloud and on-premises.

Oracle running on Azure

September 25, 2013 3 comments

Yes, your heard right

Oracle virtual machines on Windows Azure are now in preview, Multi-Factor Authentication is generally available and we have an announcement regarding SQL Database.
Microsoft and Oracle provide end-to-end support for customers running business-critical Oracle software on Windows Azure

Oracle, Oracle WebLogic Server, and the Java development environment are now available, in preview, in the Windows Azure Virtual Machines Image Gallery. These images include licenses for the Oracle software that they contain.

During the preview period, there is no charge for the included Oracle licenses. You will pay only for the Windows Azure compute and storage resources that your Virtual Machine consumes. If you would prefer to use an Oracle software license that you already own, you can do that too. Just choose a Windows Server image from the Image Gallery and install the Oracle software yourself.

Whether you bring your own Oracle license or use one of the license-included images, you now have increased flexibility and choice in where to deploy your applications and the peace of mind that comes from knowing you will be fully supported by Oracle.

To get started, sign in to the Windows Azure Management Portal and add a new Virtual Machine from the Image Gallery.

For more information, visit the Oracle information page on the Windows Azure website.

Update to improve cloud service provider resiliency in Windows Server 2012

July 13, 2013 2 comments

Microsoft released an update to improve the cloud service provider in Windows 2012

Note : The KB2870270 roll-up hotfix replaces KB2848344.  This hotfix contains the fix for Trim as well as ODX.  It is no longer necessary to disable Trim or ODX with this fix applied

The following issues are also resolved with this update:

– An Windows 2012 Hyper-V Cluster that uses CSV is moved or is toggled between directed access and redirected access when the performance monitor is running. In this situation, the performance counters no longer function.

– An Windows 2012 Hyper-V Cluster and the Virtual Machines VHD files are stored on a scale-out file share and the server is under a heavy load. In this scenario, the server may crash, and you may receive a Stop error message that resembles: STOP: 0x000000C2 (parameter1, parameter2, parameter3, parameter4) – Notes: The parameters in the Stop error message vary, depending on the configuration of the computer and not all “Stop 0x000000C2” errors are caused by this issue.

– When you use the Windows thin provisioning feature on a Windows Server 2012-based computer, you experience the same I/O delays or I/O stalls that occur during the volume-unmounting process in NTF volumes.

Plus the issues that are described in the following Microsoft Knowledge Base (KB) articles are resolved:

2796995      (http://support.microsoft.com/kb/2796995/ ) Offloaded Data Transfers fail on a computer that is running Windows 8 or Windows Server 2012
2799728      (http://support.microsoft.com/kb/2799728/ ) Virtual machine enters a paused state or a CSV volume goes offline when you try to create a backup of the virtual machine on a Windows Server 2012-based failover cluster
2801054      (http://support.microsoft.com/kb/2801054/ ) VSS_E_SNAPSHOT_SET_IN_PROGRESS error when you try to back up a virtual machine in Windows Server 2012
2813630      (http://support.microsoft.com/kb/2813630/  ) Virtual machine enters a paused state or a CSV volume goes offline when you try to create a backup of the virtual machine on a Windows Server 2012-based failover cluster
2848727      (http://support.microsoft.com/kb/2848727/ ) “Move-SmbWitnessClient” PowerShell command fails in Windows Server 2012

Resource outage when moving physical disc when using DPM to backup an HyperV Cluster.

July 13, 2013 4 comments

Microsoft just released a critical fix for hyper cluster that have been backed up by System Center DPM

“Physical Disk resource move during the backup of a Cluster Shared Volume (CSV) may cause resource outage”.

If you have configured a Windows Server 2012-based Hyper-V failover cluster CSV and your backup software perform the backup by using snapshots and the Physical Disk resource is moved to another node in the cluster, the Physical Disk resource may fail to come online if the backup of the CSV is in progress. As a result, virtual machines that rely on the CSV may crash.

A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem.
