Application Response Time for Virtual Operations
For applications running in virtualized, distributed and shared environments it will no longer work to infer the performance of an application by looking at various resource utilization statistics. Rather it is essential to define application performance by measuring response and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

Massive changes are occurring to how applications are built and how they are deployed and run. The benefits of these changes are dramatically increased responsiveness to the business (business agility), increased operational flexibility, and reduced operating costs.

The environments onto which these applications are deployed are also undergoing a fundamental change. Virtualized environments offer increased operational agility which translates into a more responsive IT Operations organization. Cloud Computing offers applications owners a complete out-sourced alternative to internal data center execution environments. IT organizations are in turn responding to public cloud with IT as a Service (IaaS) initiatives.

For applications running in virtualized, distributed and shared environments, it will no longer work to infer the “performance” of an application by looking at various resource utilization statistics. Rather it will become essential to define application performance as response time – and to directly measure the response time and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

Making a Business Case for Unified IT Monitoring
Unified monitoring solutions like Zenoss offer a cost-effective alternative for those seeking to rein-in monitoring inefficiencies. By establishing a central nerve center to collect data from multiple tools and managed resources, IT groups can gain visibility into the end-to-end availability and performance of their infrastructure. This helps simplify operational processes and reduce the risk of service disruption for the enterprise.

In large IT organizations, monitoring tool sprawl has become so commonplace that it is not unusual for administrators to be monitoring 10 to 50 solutions across various departments.

Unified monitoring solutions like Zenoss offer a cost-effective alternative for those seeking to rein-in monitoring inefficiencies. By establishing a central nerve center to collect data from multiple tools and managed resources, IT groups can gain visibility into the end-to-end availability and performance of their infrastructure.

Zerto Offsite Backup in the Cloud

What is Offsite Backup?

Offsite Backup is a new paradigm in data protection that combines hypervisor-based replication with longer retention. This greatly simplifies data protection for IT organizations. The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Why Cloud Backup?

  • Offsite Backup combines replication and long retention in a new way
  • The repository can be located in public cloud storage, a private cloud, or as part of a hybrid cloud solution.
  • Copies are saved on a daily, weekly and monthly schedule.
  • The data volumes and configuration information are included to allow VM backups to be restored on any compatible platform, cloud or otherwise.

Optimizing the way applications are delivered and managed has been an ongoing challenge in enterprise IT, and the variety of approaches over the years have been received with varying degrees of success. While every method has pros and cons, some of the most stubborn issues include time-to-deliver, application conflicts, plug-ins and licensing. The too-frequent result is high IT overhead, too many gold images and excess spending on application licenses.

Too many companies are settling on less than optimal solutions because that is all they are presented with and they are unaware of the true state of the art for application management. It is possible to dramatically reduce the number of Windows gold images, in some cases to a single image. It is possible to deliver exactly what each and every end user needs to do their job, and nothing else. It is possible for a user to log into a random system and instantly be presented with their personal desktop, all the right applications, plugins and add-ons, the right printers, and the right fonts. It is possible and it is simple.

Citrix AppDisk, when integrated with FSLogix Apps, provides a unique set of features that can improve end-user productivity, reduce IT overhead and lower the cost of desktop management. With FSLogix patent pending Image Masking technology, AppDisk gains very granular and powerful user-based policy control over every aspect of a user’s desktop and applications, and enhances the ability to distribute applications on network attached disk images. FSLogix Apps also enable AppDisks to scale to a much greater degree than any other similar technologies available today.

This document details what is possible when FSLogix is combined with Citrix AppDisk and suggests best practices for installing and configuring the products for maximum flexibility and applicability in various environments.
A New Approach to Per User Application Management
Our premise is simple: existing methodologies for delivering and deploying Windows applications are based upon outmoded ideas and outdated technology. There remains a need for a product that makes it simple for each user to have their Windows applications individually tailored for their device. When a user logs on they should see only the applications that they are licensed to use regardless of whether they are using cloud, virtual or traditional desktops.

A simple truth: Current application delivery and deployment solutions for Windows®-based desktops are often not fast enough, and the methods employed introduce complexities and limitations that cost enterprises valuable time, money and productivity. There is a strong need for a solution that is faster to deploy, simpler to use, and improves productivity rather than degrades it. In fact, the best solution would seamlessly and instantaneously personalizing the entire desktop, from profiles and printers to applications and extensions, while supporting license compliance and cost optimization. And, of course, it wouldn’t matter if the target desktops were physical, virtual, or cloud-based. FSLogix is delivering that solution today.

UNIQUE, CUTTING EDGE TECHNOLOGY

FSLogix has devised a revolutionary technique called Image Masking to create a single Unified Base Image that hides everything a logged in user shouldn’t see, providing predictable and real-time access to applications and profiles. This approach is driving unprecedented success in image reduction, with a side benefit of license cost optimization. Image masking functions identically across a wide range of Windows-based platforms, greatly simplifying the path from traditional to virtual environments, and dramatically reducing the management overhead required for enterprise desktops. This solution eliminates multiple layers of management infrastructure, creating a single, unified approach to image management, profile access, and application delivery.
User Profile and Environment Management with ProfileUnity
This whitepaper has been authored by experts at Liquidware Labs in order to provide guidance to adopters of desktop virtualization technologies. In this paper, we outline how ProfileUnity was designed to address many of the shortcomings of Roaming Profiles, and basic profile management tools that are just a step away from roaming profiles, in managing user profiles and user-authored data over multiple desktop platforms, including physical upgrades and refreshes, Windows migrations and moves to
User Profile Management on Microsoft Windows desktops continues to provide challenges.  Most Administrators find that Roaming Profiles and even Microsoft UEV generally fall short due to several factors. Profile Corruption, Lack of Customization, and lack of Enterprise Features are just some of the top shortcomings of Microsoft Windows profile management with these options.

Basic tools such as roaming profiles do not support a mixed operating environment, therefore it does not allow users to move among desktops with mixed profile versions, e.g. Windows 7, Windows 10, Server2008, 2012 r2, etc.

The lack of support of mixed OS versions makes Microsoft profile management methods a serious hindrance when upgrading/migrating operating systems. Microsoft profile management tools also only support very limited granular management, so admins do not have the ability to exclude bloated areas of a user profile or to include files and registry keys outside of the profile. Profile bloat is one of the number one reasons for long logon times on Windows desktops.

Most organizations who will upgrade from a previous Windows® OS, such as Windows 7, to Windows 10, will want the flexibility to move at their own pace and upgrade machines on a departmental or ‘as needed’ basis.  As a result, management of Microsoft profiles and migration become a huge challenge for these environments because neither operation is seamlessly supported or functional between the two operating systems.  

A user’s profile consists of nearly everything needed to provide a personalized user experience within Windows.  If one could separate out the user profile from Windows and enable dynamic profiles that can adapt to any Windows OS version, several advantages can be realized:
  • User state can be stored separately and delivered just-in-time to enable workers to roam from workspace to workspace
  • Users’ profiles can co-exist in mixed OS environments or automatically migrate from one OS to the next, making OS upgrades easy and essentially irrelevant during a point-in-time upgrade
  • Integral policies and self-managed settings, such as local and network printer management, as well as security policies, can be readily restored in the event of a PC failure or loss (disaster recovery)
Given the growing complexity and diversity of Windows desktops technologies, today’s desktop administrators are looking for better ways to manage user profiles across the ever-increasing spectrum of desktop platforms available. In this whitepaper, we will cover the issues inherent with Roaming Profiles and how ProfileUnity addresses these issues.
Vembu: The Biggest Little Data Protection Company You Probably Haven't Heard Of (Yet)
Vembu wants to do more to let people know that it exists—it wants its own name to be in the marketplace and attached to its products—especially after hearing from many customers who desire to know whom the products they rely on truly belong to. So, in the past year, Vembu established relationships with more VARs and reached out directly to select enterprise and midmarket segments. It added 400 channel partners, 180 VARs, and 300 customers in 2014 alone.

If it appears that this analyst is impressed with Vembu, he is. Vembu’s feature set surpasses what one might presume to come from a backup company that most folks (in North America at least) haven’t heard of.And although it would be easy to assume that some of Vembu’s capabilities are mere boasts, the hesitations wash away with the recognition that this is a vendor with ten years in the business, and that well over half its workforce are R&D engineers. Said another way, Vembu appears to have been quietly solving its customers’ backup challenges for more than a decade through technology, instead of marketing.

In fact, not only did Vembu not have a marketing team until 2015, but it also didn’t have a sales team to speak of. This is an incredibly engineering-focused company—one whose revenues and customers have accumulated through word of mouth. But now, Vembu is building out a solid U.S.-based sales and marketing engine focused on penetrating awareness among IT decision makers, especially decision makers in the SMB segment.

The product Vembu will push in 2015, BDR 2.0, could be a “game changer” for Vembu’s growth. BDR appears to have the potential to quite effectively address the varied requirements of small and midmarket businesses who run mixed physical and virtual IT environments and who also want to leverage the cloud.

If Vembu continues to invest as much into its North American marketing and channel outreach programs as it historically has invested into engineering its technology, then 2015 could be the year that a lot of SMBs discover the “secret” to solving a lot of their backup problems.

European and APJ businesses may know Vembu, but many U.S. IT organizations will be surprised by the solution set of this ten-year-old company that is launching its first concerted marketing push into North America.

Growing at 35% per year, Vembu branches out from its backup/recovery roots
Cloud­based backup/recovery is a cutthroat business with shrinking margins, commoditization and a surfeit of contenders trying to get a piece of the pie. The company's decision to push its resellers away from rebranding and into carrying Vembu's name on their services will give it much ­needed name/brand recognition in a crowded arena.

Vembu has grown its revenue 35% annually over the past two years and is on track to meet that mark in 2014. Key product additions this year include a suite of CRM applications and the introduction of on­premises virtual appliances (with physical appliances to come in the near future). The latter move puts Vembu in more direct competition with relatively well ­known players in the hybrid cloud backup battle.

Vembu is celebrating its 10­ year anniversary by exceeding the 60,000 ­customer milestone, sold mainly through its 4,400 channel partners. That compares with 55,000 customers and 4,000 resellers in February 2014. The company has added 400 resellers so far this year, and has begun to emphasize VARs in addition to its traditional target market of MSPs. Notable service­provider partners include Verizon's Terremark subsidiary, mindSHIFT Technologies, HostPapa and Hitachi Data Systems. The profitable Vembu claims to have exceeded 35% revenue growth in each of the past two years, and is on track for similar gains this year.

The company expects to have 200 employees by the end of 2014 (up from 160 in February), and 300 by the end of 2015. Most of its employees are near its headquarters in Chennai, India (with 65% engaged in R&D), but Vembu has been steadily expanding internationally. It opened an office in London this year, and relocated its US headquarters to Addison, Texas, where it expects to grow its workforce from 15 employees this year to 50 next year Vembu's worldwide distribution of partners roughly equates to its worldwide revenue distribution: 70% North America, 20% Europe and 10% AsiaPacific – a distribution that has remained fairly steady over the past year. However, although about 30% of its revenue comes from outside North America today, Vembu hopes to increase that to 50% in 2015. Key target markets for 2015 include the EU­5 countries, Scandinavia, Brazil and China

Does Backup Need a File System of its Own?
VembuHIVETM is an efficient cloud file system designed for large-scale backup and disaster recovery (BDRTM) application with support for advanced use-cases. VembuHIVETM can be thought of as a File System of File Systems with in-built version control, deduplication (elimination of redundant information to enhance storage reduction), encryption, and in-built error correction.

Backup is just not about storage. It’s the intelligence on top of storage. Typically when businesses think of backup, they see it as a simple data copy from one location to another. Traditional file systems would suffice if the need were to just copy the data. But backup is the intelligence applied on top of storage where data can be put to actual use. Imagine the ability to use backup data for staging, testing, development and preproduction deployment. Traditional file systems are not designed to meet such complex requirements.

With the advent of information technology, more and more organizations are relying on IT for running their businesses. They cannot afford to have downtime on their critical applications and need instant access to data in the event of disaster. Hence, a new type of file system is necessary to satisfy this need. 

VembuHIVETM manages the metadata smartly through its patent-pending technology, in a way that is agnostic to the file system of the backup, which is why we call VembuHIVETM, a file system of file systems. This helps the backup application to instantly associate the data in VembuHIVETM to any file system metadata, thereby allowing on-demand file or image restores in many possible file formats. The data and metadata storage, harness cluster file system and computing and storage.

This is a really powerful concept that will address some very interesting use cases not just in the backup and recovery domain but also in other domains, such as big-data analytics.

The key to the design of VembuHIVETM is its novel mechanism to capture and generate appropriate metadata and store it intelligently in a cloud infrastructure. The increment data (the changes with respect to a previous version of the same backup) are treated like versions in a version control system (CVS, GIT). This revolutionary way of data capture and metadata generation provides seamless support to a wide range of complex restore use cases.
