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.
Virtually every area of human endeavour that involves the use of shared resources relies on a reservation system to manage the booking of these assets. Hotels, airlines, rental companies and even the smallest of restaurants rely on reservation systems to optimize the use of their assets and balance customer satisfaction with profitability. Or, as economists would say, strike a balance between supply and demand.
So how can a modern IT environment expect to operate effectively without having a functioning capacity reservation system? The simple answer is that it can't. With the rise of cloud computing, where resources are shared on a larger scale and capacity is commoditized, modeling future bookings and proper forecasting of demand is critical to the survival of IT. Not having proper systems in place leaves forecasting to trending and guesswork - a dangerous proposition that usually results in over-provisioning and excessive capacity.

A recent IDC survey of small and medium-sized business (SMB) users revealed that 67% have a recovery time requirement of less than four hours, and 31% have a recovery time requirement of less than two hours. Additionally, IDC estimates that as many as half of all organizations have insufficient business continuity and disaster recovery plans to meet business requirements, or to even survive a disaster.
Although business continuity is perhaps the top use case for cloud computing, simply focusing on this one use limits the broad potential of cloud, especially in a hybrid cloud context.

Why Rely on Backup Shipping as Your VMware DR Solution?
people think, if you want to protect data in your virtual VMware
environment, your easiest solution is to backup VMware using snapshots
or agents. However, solutions like this, such as Veeam, can slow down
your production environment, and they are difficult to scale.
many of us understand that backup is not disaster recovery. The right
approach to a BC/DR solution is hypervisor-based replication.
With hypervisor-based replication you receive:
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.
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.
LUNs, volumes, RAID, striping and more have nothing to do
with the virtual machines and applications that run your business, and only
result in storage performance issues and management complexity. Tintri lets you
manage what matters: individual virtual machines. With the announcement of VM
Scale-out and analytics, Tintri provides virtualization scale-out technology
that makes it possible to focus on managing individual VMs instead of storage.
This paper illustrates how Tintri’s per-VM management tools
work together with predictive analytics and VM Scale-out technology to make it
possible to scale out storage while utilizing the management simplicity that is
designed into each Tintri VMstore.
Introduction – why
If you work in the data center, you’ve got a full plate.
Your leadership pushes for a hybrid-cloud strategy. Your colleagues call for
new services and projects. And you have to keep your existing (growing) virtual
footprint up and running. Besides pulling you in multiple directions, the one
thing all these items have in common is the requirement to scale.
The cloud has revolutionized the way we build IT systems within enterprises. Indeed, enterprise IT’s goal since the inception of cloud computing has been to replicate the power of cloud computing within their own data centers. The trouble is that cloud computing systems were built net-new, which meant they could start from scratch and thus be more innovative with the use of cloud-based resources using the most modern technology and approaches available. Enterprises don’t have the same luxury. Decades of enterprise hardware and software purchases exist at different levels of maturation, and those structures must also support mission-critical systems in operations.
However, things are changing. New technology now provides enterprises with the public cloud experience,which includes:
