Data abstraction overcomes data structure incompatibility by transforming data from its native structure and syntax into reusable views and data services. But some data abstraction approaches work better than others. Composite data virtualization is an optimal way to implement an abstraction layer at enterprise scale. 

For many years network administrators have expected security breaches to come from outside an organization or at the upper layers of the OSI model. This paper will focus on securing layer 2 switching at the access layer through port security and preventing denial of service (DoS) attacks at layer 2. 

This white paper discusses a gradual approach to building a new server room. Find out key factors to consider as you proceed with your initiative, such as site selection and size, energy, backup, and more. 

A new approach to Business Process Management (BPM) is the use of BPM and SOA together in a layering strategy. This white paper explores the BPM layered concept and offers a case study of how ABN AMRO, one of the world's largest financial institutions, has benefited from its deployment. 

Overlay transport virtualization (OTV) can help solve many of the challenges in today's increasingly virtualized and geographically dispersed data centers. Access this paper for a high-level overview of this technology and how it differs from the alternatives. 

Aging server rooms can cause serious breakdowns in computing capacity, but the damage to relationships and revenue can be especially great for a small to medium-sized business. Take a look at this comprehensive resource to learn the key considerations for updating your server room, specifically tailored for the small to medium-sized business. 

In this paper, learn why the database layer is so important to the software selection of an enterprise resource planning (ERP) system. Also compare Oracle database to SQL Server databases. 

This paper outlines the things you must consider when thinking about the feasibility of replacing a WAN provider’s provider (P) and provider edge (PE) devices with routers. This paper examines these considerations in greater detail, to see where any potential problems might arise. 

Typical IT departments feature islands of isolated infrastructure, leading to inefficient use of servers. The "application grid" concept allows data centres to run more efficiently, using less hardware and less software. This paper explains. 

Any virtualization layer or hypervisor introduces a new set of demands to a server or blade environment. This e-book explains the process of virtualizing the I/O layer, how to manage it and what challenges remain for this disruptive technology. 

<p>The web and email are not IT’s friends. They create risk and increase the workload because they distribute and prolong the payoff of known and unknown threats. Layering new and traditional techniques, including anti-malware, anti-spam, intrusion prevention, and application whitelisting, throughout the enterprise will minimize those risks.</p> 

While a DDoS attack can be damaging to any organization, DDoS attacks specifically at the application-layer can be more ominous. Understanding these attacks are the first step to keeping your organization protected. In this e-guide, explore how DDoS is being used, what you can do to stop them, the future of the web threat landscape and more. 

In this transcript, senior enterprise IT architect Nelson Ruest breaks down the seven different layers of the server virtualization architecture, and explains the role the hypervisor plays in the success of that infrastructure.
