#Microsoft finds a new way to deliver a private #cloud in a box – #Azure via @maryjofoley
Interesting!!!! 🙂
It took three years from when it was first announced, but Microsoft may have found a way to deliver a private cloud in a box.
The company’s vision and strategy for doing this has gone through many twists and turns.
Microsoft’s original plan was to provide its largest partners and even a few, select enterprise users a so-called Azure Appliance. Announced in 2010, the Azure Appliances were to be carried by Dell, Fujitsu and HP. These OEMs were to provide the servers which could be installed in partner and select enterprise customers’ datacenters. Microsoft was supposed to provide and maintain Windows Azure as a service to these servers.
The only partner that ever delivered an Azure Appliance was Fujitsu, which announced availability in August 2011. But some time in the past few months, Microsoft ended up dropping its Azure Appliance plans, without ever officially announcing it was dead.

Interesting and a good blog post by Sameer Mehta.
World of BYOD
Bring your own device (BYOD) initiatives are enabling employees to bring their own personal devices to work and allowing them corporate access to services such as Email. We did a recent audit using our ability to integrate with security incident and event management (SIEM) systems for a customer. The audit provided visibility into their ActiveSync traffic and found devices that belonged to executives that were not under IT management. Here’s a snapshot of their BYO devices.
There are several reasons to enable such access – for example, to boost employee productivity or convenience of accessing email from any device. Having said that, as Uncle Ben puts it, “with great power comes great responsibility”, and this responsibility is on the IT administrator from a security point of view. It’s IT’s responsibility to make sure that corporate data is not compromised or leaked in the following scenarios:
- What happens when this personal device is lost or stolen?
- What happens if this device is jailbroken or rooted?
- What happens if this device ends up outside an approved geofence. For example, outside of the US?
- What happens if the user inadvertently installs an application that has the ability and access to the entire device memory, thereby having unauthorized access to corporate data?
End User’s perspective on Enterprise Mobility
End users want access to corporate services such as email, intranet, ability to share and collaborate over documents, and also use 3rd party applications such as Evernote, Quick Office or GoodReader. With mobile solutions such as XenMobile MDM, CloudGateway, ShareFile and GoToAssist, Citrix provides ubiquity i.e. ‘access any app. from any device’, and a unified view for applications with an enterprise app store, documents via ShareFile. Having said that, since the user is accessing multiple applications; end user experience is a key component of mobility solutions. For example, bootstrap authentication and provide single sign on (SSO) to other applications.
Enterprise IT perspective on BYOD
As IT is providing access to corporate services, the main concern is around data loss prevention (DLP) and protecting corporate content on the mobile device. This means, encrypting data at rest for application data, and documents that are hosted either on Sharepoint, Network File share or Cloud storage. From a DLP perspective, for security conscious organizations, the mobile solutions bundle, which includes XenMobile MDM and CloudGateway…

#Sanbolic Brings Public Cloud Economics to the Enterprise – #Melio
Ok, I must say that this product is great!!! If you haven’t looked at it before then please do! And contact us at EnvokeIT if you want more details!
Sanbolic Enables Distributed Flash, SSD and HDD to Achieve Enterprise Systems Capability and Scale-Out In Server-Side and Commodity Storage Deployments
Waltham, MA – (March 18, 2013) – Sanbolic® today announced the general availability of its Melio version 5 (Melio5™) software – delivering distributed scale-out, high-availability and enterprise data services through software. Server-side flash has seen rapid adoption for applications such as hyperscale web serving, but limited adoption in general purpose enterprise applications. With the launch of Melio5, Sanbolic enables enterprise customers to dramatically improve their storage infrastructure economics by enabling server-side flash, SSD and HDD as primary persistent storage. Melio5 aggregates across nodes for scale-out and availability while providing RAID, remote replication, quality of Service (QoS), snapshots and systems functionality through a software layer on commodity hardware. This provides customers with the ability to deploy commodity and server-based storage architecture with similar economics and flexibility as public cloud data centers such as Google and Facebook.
With validation by hundreds of enterprise and government organizations running in production, Melio volume management and file system technology addresses the needs of high performing cost effective storage infrastructure on-premise. Melio5’s architecture is designed to scale up to 2,048 nodes and up to 65,000 storage devices enabling linear performance scalability in a cluster.
Melio5 also eliminates the need to deploy a redundant flash caching layer in front of legacy storage area network (SAN) hardware by directly incorporating flash into hybrid volumes and intelligently placing data based on file system access profiles. A hybrid volume will place random access data such as file system metadata on flash sectors while placing sequential data on low cost hard disk drives to greatly reduce the cost of capacity. The result is a highly scalable, high performance storage system, with a much lower cost than legacy storage arrays.
“Typically, server and disk drive vendors operate on gross margins in the 20-30% range. Storage array vendors, on the other hand, are often twice that or more,” said Eric Slack, Senior Analyst,Storage Switzerland. “Sanbolic’s approach leverages the architecture that the big social media and public cloud companies use, to fix this problem. By replacing storage arrays (and storage array margins) with commodity server and disk drive hardware and enabling it with intelligence through software, companies can significantly reduce storage infrastructure costs.”
Terri McClure, Senior Analyst, Enterprise Strategy Group (ESG), stated, “Sanbolic’s Melio5 software enables corporate users to take advantage of flash and SSD in conjunction with commodity hardware to create an intelligent, cost effective, and high performance storage architecture like the huge public cloud companies run, while still ensuring enterprise workload scalability and high availability.”
“Melio5 lets us solve one of the biggest challenges for our customers today – the upfront and management cost for storage – without sacrificing systems capability or performance. The Lego-like modular capability of Melio allows our customers to scale-out their storage and servers based on off-the-self commodity components, without downtime,” said Mattias Tornblom, CEO, EnvokeIT.
“LSI and Sanbolic’s shared vision and complementary products help customers to dramatically improve the performance, flexibility and economics of their on-premise storage infrastructure,” said Brent Blanchard, Senior Director of Worldwide Channel Sales and Marketing, LSI Corporation. “LSI’s Nytro™ family of server-side flash acceleration cards and leading SAS-based server storage connectivity solutions…

UCS and XenDesktop – Best Practises guide #Cisco #UCS #XenDesktop #VXI
I must admin that the Cisco, NetApp and Citrix story around providing a great offering around a complete server hardware, storage and networking solution!
I’m currently attending the 5h SYNBCN12-614W-Platform training on XenDesktop with Cisco Unified Computing System and NetApp session here and I must say that I like the offering due to the broad capabilities of the products included in the solution.
I think that one of the real added values that companies will like is that you have ONE (1) support contact (Cisco) for the whole solution, then Cisco wodk with the others to solve any potential issue etc.
And while playing around here the trainer also mentioned this best practise guide, and it looks good;
Additional info about the Cisco VXI – Desktop Virtualization can be found here.

XenServer 6.1 Releases
“Over the past several months, literally hundreds of people have asked me the question “When will Tampa release?” I am pleased to announce that earlier today, “Tampa” officially reached GA as XenServer 6.1. Within engineering, this is officially considered a “cloud centric” release. While on the surface that would seem to indicate a lack of features for traditional server virtualization and desktop, but the reality is quite different. When you consider that a cloud runs in a datacenter, and that cloud workloads typically translate into some pretty large VM densities, all with a requirement for a high degree of workload isolation; “cloud centric” actually translates into a set of pretty stringent performance requirements. To illustrate the point, let’s consider three key features, live storage migration, network security and VM conversion.
When you look at some of the most successful clouds, you’ll quickly see that the concept of resource pools are somewhat limiting. Regardless of the size of the pool, if your cloud is successful, eventually you’re going to have more customers than can fit in your cluster or pool. During the design phase for Storage XenMotion, we accounted for this with the result being a shared nothing live storage migration solution which works equally well across all storage types and without being confined to an arbitrary resource pool concept. While designed for the cloud, it fully supports enterprise storage management requirements, and even supports live VM migration between local storage for those cases where shared storage wasn’t implemented.”
