The Linux Enterprise Cluster by Karl Kopper Pdf

The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited resources, place them on a normal computer network, and install free software so that the computers act together like one powerful server. This makes it possible to build a very inexpensive and reliable business system for a small business or a large corporation. The book includes information on how to build a high-availability server pair using the Heartbeat package, how to use the Linux Virtual Server load balancing software, how to configure a reliable printing system in a Linux cluster environment, and how to build a job scheduling system in Linux with no single point of failure. The book also includes information on high availability techniques that can be used with or without a cluster, making it helpful for System Administrators even if they are not building a cluster. Anyone interested in deploying Linux in an environment where low cost computer reliability is important will find this book useful. The CD-ROM includes the Linux kernel, ldirectord software, the Mon monitoring package, the Ganglia package, OpenSSH, rsync, SystemImager, Heartbeat, and all the figures and illustrations used in the book.

High Availability IT Services by Terry Critchley Pdf

This book starts with the basic premise that a service is comprised of the 3Ps-products, processes, and people. Moreover, these entities and their sub-entities interlink to support the services that end users require to run and support a business. This widens the scope of any availability design far beyond hardware and software. It also increases t

Breaking the Availability Barrier by Bill Highleyman Pdf

As our daily lives and corporate well-being become more dependent upon computers, system reliability grows increasingly important. No longer are frequent system outages acceptable. In many cases, failure intervals must now be measured in centuries. Even current fault-tolerant computing systems will fail once every five or ten years. This book is the first in a three-part series on active/active systems. It describes techniques that can be used today for extending system failure times from years to centuries, often at little or no additional cost. The techniques described include splitting a large system into smaller, cooperating independent nodes. Copies of the application's database are distributed across the nodes. It is shown that these techniques significantly reduce the number of system failure modes and increase the level of sparing. As a result, the loss of a single node's capacity occurs far less frequently than the loss of all capacity when the equivalent monolithic system fails. Furthermore, the loss of more than one node's worth of capacity is almost never. Central to these techniques is the requirement that all database copies that are distributed across the network must be kept in synchronism. Several methods available today for maintaining synchronism are described. They include asynchronous data replication, synchronous data replication, and network transactions.

Enhancing Business Continuity and IT Capability by Nijaz Bajgorić,Lejla Turulja,Semir Ibrahimović,Amra Alagić Pdf

Enterprise servers play a mission-critical role in modern computing environments, especially from a business continuity perspective. Several models of IT capability have been introduced over the last two decades. Enhancing Business Continuity and IT Capability: System Administration and Server Operating Platforms proposes a new model of IT capability. It presents a framework that establishes the relationship between downtime on one side and business continuity and IT capability on the other side, as well as how system administration and modern server operating platforms can help in improving business continuity and IT capability. This book begins by defining business continuity and IT capability and their importance in modern business, as well as by giving an overview of business continuity, disaster recovery planning, contingency planning, and business continuity maturity models. It then explores modern server environments and the role of system administration in ensuring higher levels of system availability, system scalability, and business continuity. Techniques for enhancing availability and business continuity also include Business impact analysis Assessing the downtime impact Designing an optimal business continuity solution IT auditing as a process of gathering data and evidence to evaluate whether the company’s information systems infrastructure is efficient and effective and whether it meets business goals The book concludes with frameworks and guidelines on how to measure and assess IT capability and how IT capability affects a firm’s performances. Cases and white papers describe real-world scenarios illustrating the concepts and techniques presented in the book.
