Identify three good reasons why a Tier 2 data center would not meet Facebook’s needs. Reliability and availability:
Tier 2 data centers offer a basic level of redundancy and
uptime, but they lack the high availability required by Facebook. Facebook's massive user base and the criticality of its services demand a data center with higher levels of redundancy, fault tolerance, and continuous availability. Tier 2 data centers typically have a single path for power and cooling, making them more susceptible to downtime due to equipment failures or maintenance activities.
Scalability and capacity: Tier 2 data centers often have limited scalability and capacity
compared to higher-tier data centers. Facebook experiences exponential growth in data storage and processing requirements due to its large user base and content-sharing activities. A Tier 2 data center may struggle to keep up with the demand for increased computing capacity, storage, and network bandwidth, leading to performance bottlenecks and scalability challenges.
Energy efficiency and cost optimization:
Facebook has made significant efforts to
design energy-efficient data centers to minimize operational costs and environmental impact.
Tier 2 data centers do not prioritize energy efficiency to the same extent as higher-tier data
centers. Given Facebook's commitment to sustainability and reducing operational expenses, a
Tier 2 data centers may not align with their goals and requirements.
Your organization has decided to outsource its data center operations. You are responsible for performing an initial assessment of service organizations that wish to compete for this business. Develop a set of six questions you can use to determine if an organization’s data center is a 1, 2, 3, or 4 data centers. 1.
What level of redundancy does your data center offer for power and cooling systems?
(Tier 1: Basic, Tier 2: Redundant components, Tier 3: Concurrently maintainable, Tier 4: Fault-tolerant) 2.
How do you ensure continuous uptime and availability in case of equipment failures or
maintenance activities? (Tier 1: Limited redundancy, Tier 2: Basic redundancy, Tier 3:
Concurrently maintainable, Tier 4: Fault-tolerant) 3.
What are your provisions for scalability and capacity expansion to meet increasing
demands? (Tier 1: Limited scalability, Tier 2: Some scalability, Tier 3: Scalable, Tier 4:
Highly scalable) 4.
How do you handle security measures, including access controls, surveillance, and
physical security? (Tier 1: Basic security measures, Tier 2: Enhanced security measures, Tier
3: Advanced security measures, Tier 4: Stringent security measures) 5.
What level of connectivity and network redundancy do you provide? (Tier 1: Basic
connectivity, Tier 2: Redundant connections, Tier 3: Multiple carriers, Tier 4: Multiple
carriers with fault-tolerant paths) 6.
How do you ensure energy efficiency and environmental sustainability within your data
center operations? (Tier 1: Limited focus on efficiency, Tier 2: Some energy-saving
measures, Tier 3: High energy efficiency, Tier 4: Optimal energy efficiency)
Based on business needs, should the data center at your place of work (or university) be designed and operating as a tier 1, 2, 3, or 4 data centers? Explain why. If the organization requires high availability, continuous uptime, scalability, and the ability to handle equipment failures or maintenance activities without disruptions, a Tier 3 or Tier 4 data center would be more suitable. This ensures concurrent maintainability and fault tolerance, providing a robust infrastructure with redundant components, backup power systems, cooling,

and network connectivity. However, if the organization's services can tolerate occasional downtime and have more flexibility in terms of scalability and capacity, a Tier 2 data center might be sufficient. It is important to assess the cost implications and evaluate the trade-offs between higher tiers and the level of business continuity required. The decision should align with
the organization's budget, risk tolerance, and the criticality of the services being provided.
