Book Description:
This book starts with the basic premise that a service is comprised of the 3Psproducts, 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 the potential for service failure for reasons beyond just hardware and software; the concept of logical outages.High Availability IT Services details the considerations for designing and running highly available "services" and not just the systems infrastructure that supports those services. Providing an overview of virtualization and cloud computing, it supplies a detailed look at availability, redundancy, fault tolerance, and security. It also stresses the importance of human factors.The book starts off by providing an availability primer and detailing the reasons why you need to be concerned with high availability. Next, it outlines the theory of reliability and availability and the elements of actual practices in this high availability (HA) area, including Service Level Agreements (SLAs) and Change Management.Examining what the major hardware and software vendors have to offer in the HA world, the book considers the ubiquitous world of clouds and virtualization as well as the availability considerations they present.The book examines high availability concepts and architectures such as reliability, availability, and serviceability (RAS); clusters; grids; and redundant arrays of independent disks (RAID) storage. It also covers the role of security in providing high availability, cluster offerings, emergent Linux clusters, online transaction processing (OLTP), and relational databases.
Best Practices for High Network Uptime
Whether your network is a complex carrier or just a few machines supporting a small enterprise, JUNOS High Availability will help you build reliable and resilient networks that include Juniper Networks devices. With this book's valuable advice on software upgrades, scalability, remote network monitoring and management, high-availability protocols such as VRRP, and more, you'll have your network uptime at the five, six, or even seven nines -- or 99.99999% of the time.Rather than focus on "greenfield" designs, the authors explain how to intelligently modify multi-vendor networks. You'll learn to adapt new devices to existing protocols and platforms, and deploy continuous systems even when reporting scheduled downtime. JUNOS High Availability ...
High Availability with RAC, Flashback and Data Guard
Attain real solutions for current availability challenges. Based on a 'DBA-centric approach to High Availability, Oracle Database 10g High Availability concentrates on explaining Oracle Database 10g technologies and practices to database administrators, covering general availability, real application clusters (RAC), disaster planning and recovery, and distributed database solutions. Hardware and application needs are also taken into account. While Oracle Database 10g is the main focus, many of the options discussed are available in earlier database releases. Organized to provide conceptual understanding of High Availability, included are 'HA Workshops, step-by-step instructions to get you through certain implementations, plus real-world inspired case...
