Picture this: You
round the corner and your CEO or another executive ambushes you with a question
about an IT issue that’s keeping him up at night…
Business leaders and executives often need quick answers
from IT, especially when there’s an issue underway and the ripple effects are
beginning to spread. How you respond in
these moments could make or break your career.
(Here’s a hint: they won’t want
This eBook will prepare you for those moments, showing you
how to think about IT ‘as-a-Service’ and communicate in the language your
leaders and executives understand, and the terms they care about.
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.
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. This helps simplify operational processes and reduce the risk of service disruption for the enterprise.
This paper can help you make an effective business case for moving to a unified monitoring solution. Key considerations include:
• The direct costs associated with moving to a unified monitoring tool• The savings potential of improved IT operations through productivity and efficiency• The business impact of monitoring tools in preventing and reducing both downtime and service degradation

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.
Download this paper to learn how to manage the demand pipeline for new workload placements in order to improve the accuracy of capacity forecasting and increase agility in response to new workload placement requests.
This is not a paper on disk defrag. Although conceptually similar, it describes an entirely new approach to server optimization that performs a similar operation on the compute, memory and IO capacity of entire virtual and cloud environments.
Capacity defragmentation is a concept that is becoming increasingly important in the management of modern data centers. As virtualization increases its penetration into production environments, and as public and private clouds move to the forefront of the IT mindset, the ability to leverage this newly-found agility while at the same driving high efficiency (and low risk) is a real game changer. This white paper outlines how managers of IT environments make the transition from old-school capacity management to new-school efficiency management.
The hybrid cloud has been heralded as a promising IT operational model enabling enterprises to maintain security and control over the infrastructure on which their applications run. At the same time, it promises to maximize ROI from their local data center and leverage public cloud infrastructure for an occasional demand spike. However, these benefits don’t come without challenges.
In this whitepaper you will learn:• The challenges in implementing an effective hybrid cloud• How key vendors are addressing their challenges• How to answer what, when and where to burst

Active Directory (AD) offers IT system administrators a central way to
manage user accounts and devices in an IT infrastructure network. Active
Directory authenticates and authorizes users when they log onto devices
and into applications, and allows them to use the settings and files
across all devices in the network. Active Directory services are
involved in multiple aspects of networking environments and enable
interplay with other directories. Considering the important role AD
plays in user data-management and security, it’s important to deploy it
properly and consistently follow best practices.
Active Directory Basics is a tutorial
that will help you address many AD management challenges. You’ll learn
what really goes on under the Active Directory hood, including its
integration with network services and the features that enable its many
great benefits. This white paper also explains how administrators can
make changes in AD to provide consistency across an environment.
In addition, the Active Directory Basics tutorial explains how to:
