8. Case Analysis

9. CASE ANALYSIS Presents the incident of Tribunes Server Consolidation Consolidation resulted in Dual Site Enterprise Architecture, incorporating two 72-Processor Sun 15Ks, 1Gbps Dark-Fiber link, new storage & Optical Switches Motivating factors for the project included: Bolstering backup and recovery Wanting hardwares and softwares that would enhance daily production Finding better and easier way to manage old hardwares

10. IT INFRASTRUCTURE
Before Consolidation Facility located in a single location Half a decade old important applications, including advertising, circulation, and database marketing programs- having high maintenance cost Under-utilized & under-available hardware assets Included two Sun Ultra Enterprise 10000 (E10K) servers, with 14-way Sun Ultra-Enterprise 5500 boxes, and a mainframe system for marketing database and other workloads

11. IT INFRASTRUCTURE
After Consolidation Two Data Centers at about 2-mile distance A scalable & available datacenter infrastructure Worked with AT&T, EMC Corp., Nortel Networks, and Sun Microsystems Inc. Anchored by two 72-processor Sun Fire Enterprise 15K servers, optical switches, new storage of 38TB, seven Solaris domain application partitions & a 1Gbps black fiber

12. IT INFRASTRUCTURE
After Consolidation

13. Challenges & Recovery
Coding Error –> 5-hour delay->
Cost: $1 million
“The server consolidation project ‘was the right move for us’” Darko Dejanovic, VP and chief technology officer of Tribune Co.
Project finished 1 week ahead with 10% less budget

14. CONSEQUENCES AND FUTURE PLANS
Outcomes
Time for nightly batch-processing task dropped from about five hours to as little as one hour.
Can add applications without increasing head count.
Increased application performance- increased user productivity
Cost savings
Change-Control Factor

15. CONSEQUENCES AND FUTURE PLANS
Editorial Application
Operations & Circular Application
Hardware Consolidation
Software Consolidation
95% classified-ad & 90% ad-sales Standardized processes
Disparate Billing & Ad Apps
Single Billing & Ad App
more efficient use of the Sun server cluster- for server capacity and clustering

16. CASE QUESTIONS & ANSWERS

17. 1. Review the five characteristics of infrastructure architecture and rank them in order of their potential impact on the Tribune Co.’s business.
1.Flexibility
2.Scalability
3.Reliability
4.Availability
5.Performance
1.Performance & Availability
2.Reliability
3.Flexibility
4.Scalability

18. 2. What is the disaster recovery cost curve? Where should the Tribune Co. operate on the curve?
A disaster recovery cost curve charts (1) the cost to the organization of the unavailability of information and technology and (2) the cost to the organization of recovering from a disaster over time.

19. 2. What is the disaster recovery cost curve? Where should the Tribune Co. operate on the curve?
Pros
¤Little to no downtime.
¤No data loss—data is always current
¤Can be configured for automatic failover
¤Easiest to revert back to normal environment after disaster scenario
Active-Active Replication System

20. 2. What is the disaster recovery cost curve? Where should the Tribune Co. operate on the curve?
Cons
¤High cost for extra equipment and software (Highest cost of all the other possible solutions)
¤Increased complexity
¤Requires reliable (redundant) network between locations
¤Potential exists for network connectivity issues between the two sites to result in a split-brain condition
¤During a disruptive event, half of available resources are lost
Active-Active Replication System

21. 2. What is the disaster recovery cost curve? Where should the Tribune Co. operate on the curve?

22. 3. Define backups and recovery. What are the risks to the Tribune’s business if it fails to implement an adequate backup plan?
Recovery
Backup exact copy of a system’s information that can be used to reconstruct that data can be physical and/or logical ability to get a system up and running in the event of a system crash or failure includes restoring the information backup.

23. 3. Define backups and recovery. What are the risks to the Tribune’s business if it fails to implement an adequate backup plan?
missed publication deadline
lost and irreplaceable advertising income
lost time in production
shifts cannot be done to make up
extreme damage to reputation, compromised legal position, fines, court sanctions and raised profile as a litigation target, & in extreme case a slow but sure bankruptcy.

24. 4. Why is a scalable and highly available enterprise architecture critical to the Tribune Co.’s current operations and future growth?
Scalable System
performance increases (or decreases) after hardware is added or removed somewhat proportionally to the capacity added or removed
Highly Available System provides user access for a high percentage of scheduled time by reducing unscheduled outages and mitigating the impact of scheduled downtime
Virtualization, new servers, watchdog to detect failed servers, redundant data centers etc.

25. 4. Why is a scalable and highly available enterprise architecture critical to the Tribune Co.’s current operations and future growth?
Why?
Industry demands a highly available & scalable Enterprise Architecture
In Case
Scalability
Partitioning applications into seven Solaris domains
38TB of Data Storage
Availability
active-active clustering (business continuity software and system)

26. 5. Identify the need for information security at the Tribune Co.
Information Security
application of Administrative, Physical, and Technical controls to protect the Confidentiality, Integrity & Availability of information.
Answer these Does Tribune Co. have information that needs to be kept confidential? Does Tribune have information that needs to be accurate? Does Tribune have information that must be available when needed?

27. 6. How could the Tribune Co. use a classified ad Web service across its different businesses? Write a Web Service Ad Single package to increase availability Shared services and decreased costs
