Servers occupy a place in computing similar to that occupied by minicomputers in the past, which they have largely replaced. The typical server is a computer system that operates continuously on a network and waits for requests for services from other computers on the network. Many servers are dedicated to this role, but some may also be used simultaneously for other purposes, particularly when the demands placed upon them as servers are modest.
The technologies examined reduce operational expenses (OpEx), not capital expenses (CapEx) that has traditionally been the focus of virtualization. Many companies implemented virtualization with the goal of saving money in the form of fewer servers to buy (with a side benefit of reducing the footprint of the servers and lowering the required power and cooling). Most of the savings were in capital, but do not expect the same with many of the technologies listed here, because some may even require some additional capital expenditures (at least for software) in order to save on the day-to-day operations of IT. The bigger cost in running an IT department is in the OpEx category anyway, so savings there are recurring savings.

The IBM DB2 pureScale feature is designed to address your current and future business needs for continuous availability. This white paper introduces DB2 pureScale—what it looks like, where it comes from, and how it allows you to scale out your database on a set of servers in an active-active configuration that combines high availability with truly transparent application scaling.
Partners and customers expect instantaneous response and continuous uptime from data systems, but the volume and velocity of data make it difficult to respond with agility. IBM PureData System for Transactions enable businesses to gear up and meet these challenges.
Most enterprise datacenters are so cluttered with individually constructed servers, including database servers, that staff time is largely taken up with just the maintenance of these systems. As a result, IT service to business users suffers, and the agility of the enterprise suffers. Integrated systems represent an antidote to this problem. By dramatically reducing the amount of setup and maintenance time for the applications and databases they support, integrated systems enable the technical staff to spend more of their time supporting users and enabling the enterprise to thrive.
This planning and implementation guide discusses planning topics, architectural considerations, and configuration steps relevant before and after launching the necessary AWS services such as Amazon Elastic Compute Cloud (Amazon EC2) and Amazon Virtual Private Cloud (Amazon VPC) to run a high-availability and site-resilient Exchange architecture.
The new IBM System x3650 servers provide the power midmarket customers need to improve the performance of mission-critical applications, such as Microsoft Exchange, while offering dramatic cost savings and environmental customer benefits.
Clabby white paper that highlights the benefits and advantages that IBM brings to the market with its breakthrough technology and products, providing the right solution and value for customers' issues compared to Cisco UCS.
Between the proliferation of mobile devices and the ever increasing amount of content on the web, DNS usage has seen a huge increase in recent years. Meanwhile, DNS continues to be a tempting target for attackers, and when they succeed in disrupting DNS, all external data center services are affected. For organizations confronting these growth and security challenges, F5’s new full proxy architecture for DNS provides a complete solution for global, local, and cloud load balancing.
The use of SSL encryption for all enterprise Internet traffic is growing steadily. Applications that make use of SSL – such as SharePoint, Exchange, WebEx, Salesforce.com and Google Apps – are commonplace. Even email applications like Gmail, Yahoo, and Zimbra are being used in workplace environments as hosted email or BYOD apps.
It’s clear that organizations now need complete visibility into the SSL traffic coming across the WAN. They need the ability to preserve complete network and web histories from encrypted network and web traffic for compliance, regulatory and logging requirements. Blue Coat has solutions today to address the SSL dilemma.
