Who should attend: Novice and advanced UNIX system and network administrators, and UNIX developers concerned with building applications that can be deployed and managed in a highly resilient manner. A basic understanding of UNIX system programming, UNIX shell programming, and network environments is required.

This course will explore procedures and techniques for designing, building and managing predictible, resilient UNIX-based systems in a distributed environment. Hardware redundancy, system redundancy, monitoring and verification techniques, network implications, system and application programming issues will all be addressed. We will discuss the trade-offs between cost, reliability and complexity. Topics to be covered:

	High availability - who does (and does not) need it
	Defining uptime and cost - "big rules" of system design
	Disk and data redundancy - RAID and SCSI arrays
	Host redundancy in HA configurations
	Network dependencies
	Application system programming concerns
	Anatomy of failovers - applications, systems, management tools
	Planning disaster recovery sites and data updates
	Security implications
	Upgrade and patch strategies
	Backup systems - off-site storage, redundancy and disaster recovery issues
	Managing the system managers, processes, verification
