(1)
Organization needs 20 servers for 5 years.
For Buy-Alternative calculation:
The given inputs are,
- Server cost is $2,500.
- Software costs is $1,250.
- Straight-line depreciation is 3 years.
- Maintenance percentage is 3 %.
The formula to calculate the total buy payment is given below:
Total buy payment = Depreciation + Maintenance
For 1 year:
Server cost = Server cost × servers purchased
= 2500 × 20
= $50,000
Software cost = Software cost × servers purchased
= 1250 × 20
= $25,000
Depreciation1 = (Server1 cost + software1 cost) / Depreciation year
= (50000 + 25000) / 3
= $25,000
Interest Expense = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Maintenance = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Total buy payment = Depreciation + Maintenance
= 25000 + 1500
= $26,500
For 2 year:
Depreciation2 = Depreciation1
= $25,000
Interest Expense = Server cost × maintenance percentage
= 0 × 0.03
= 0
Maintenance = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Total buy payment = Depreciation + Maintenance
= 25000 + 1500
= $26,500
For 3 year:
Depreciation3 = Depreciation1
= $25,000
Interest Expense = Server cost × maintenance percentage
= 0 × 0.03
= 0
Maintenance = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Total buy payment = Depreciation + Maintenance
= 25000 + 1500
= $26,500
For 4 year:
Depreciation = (Server cost + software cost) / Depreciation year
= (0 – 0)/3
= 0
Interest Expense = Server cost × maintenance percentage
= 0 × 0.03
= 0
Maintenance = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Total buy payment = Depreciation + Maintenance
= 0 + 1500
= $1,500
For 5 year:
Depreciation = (Server cost + software cost) / Depreciation year
= (0 – 0)/3
= 0
Interest Expense = Server cost × maintenance percentage
= 0 × 0.03
= 0
Maintenance = Server cost × maintenance percentage
= 50000 × 0.03
= $1,500
Total buy payment = Depreciation + Maintenance
= 0 + 1500
= $1,500
Total Server cost:
Total Server cost = Sum of the server cost for 5 years
= 50000+0+0+0+0
= $50,000
Total Software cost:
Total Software cost = Sum of the software cost for 5 years
= 25000+0+0+0+0
= $25,000
Total depreciation:
Total depreciation= Sum of the depreciation for 5 years
= 25000+25000+25000+0+0
= $75,000
Salvage value:
Salvage value = (Total Server cost + Total Software cost) – Total depreciation
= 50000+25000 – 75000
= $0.00
Total cost:
Sum of yearly costs less salvage value = sum of totals buy expenses for 5 years
= 26,500 + 26,500 + 26,500 + 1,500 + 1,500
= $82,500
Finally, the sum of the yearly costs less salvage value is,
Total = total cost – salvage value
= 82,500 – 0.00
= $82,500
Therefore, the sum of the yearly costs less salvage value for buy-alternative is “$82,500”.
For Lease-Alternative calculation:
The given inputs are,
- The cost of 3 year lease is $285.
- The cost of 2 year lease is $335.
- The cost of 1 year lease is $415.
- Discount for 20 to 30 computers is 5%.
- Discount for 31 to 50 computers is 10%.
The formula to calculate the total lease payment is given below:
Total lease payment = (Payment for leased servers – Discount amount) × 12
For 1 year:
Payment for leased servers = Payment per unit × Servers leased
= 285 × 20
= 5700
Discount amount = Payment for leased servers × Discount
= 5700 × 0.05
= 285
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (5700 – 285) × 12
= 5415 × 12
= $64,980
For 2 year:
Payment for leased servers = Payment per unit × Servers leased
= 285 × 20
= 5700
Discount amount = Payment for leased servers × Discount
= 5700 × 0.05
= 285
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (5700 – 285) × 12
= 5415 × 12
= $64,980
For 3 year:
Payment for leased servers = Payment per unit × Servers leased
= 285 × 20
= 5700
Discount amount = Payment for leased servers × Discount
= 5700 × 0.05
= 285
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (5700 – 285) × 12
= 5415 × 12
= $64,980
For 4 year:
Payment for leased servers = Payment per unit × Servers leased
= 335 × 20
= 6700
Discount amount = Payment for leased servers × Discount
= 6700 × 0.05
= 335
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (6700 – 335) × 12
= 6365 × 12
= $76,380
For 5 year:
Payment for leased servers = Payment per unit × Servers leased
= 335 × 20
= 6700
Discount amount = Payment for leased servers × Discount
= 6700 × 0.05
= 335
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (6700 – 335) × 12
= 6365 × 12
= $76,380
Total cost:
Total = Sum of Lease payments for 5 years
= 64,980 + 64,980 + 64,980 + 76,380 + 76,380
= $347,700
Therefore, the sum of the yearly costs for lease-alternative is “$347,700”.

For 3 year:
Server2 cost = Server2 cost × servers purchased
= 2500 × 20
= $50,000
Software2 cost = Software2 cost × servers purchased
= 1250 × 20
= $25,000
Depreciation3 = Depreciation2 + (Server3 cost + software3 cost) / Depreciation year
= 25,000 + (50000 + 25000)/3
= 25,000 + 25,000
= $50,000
Interest Expense = (Server2 cost × maintenance percentage)
= 50000× 0.03
=$1,500
Maintenance = (Server1 cost × maintenance percentage) + (Server2 cost × maintenance percentage)
= (50000 × 0.03) + (50000 × 0.03)
= 1500 + 1500
= $3,000
Total buy payment = Depreciation + Maintenance
= 50000+3000
= $53,000
For 4 year:
Depreciation4 = Depreciation2
= $25,000
Interest Expense = Server cost × maintenance percentage

Total depreciation:
Total depreciation= Sum of the depreciation for 5 years
= 25000+25000+50000+25000+25000
= $150,000
Salvage value:
Salvage value = (Total Server cost + Total Software cost) – Total depreciation
= 100000+50000 – 150000
= $0.00
Total cost:
Sum of yearly costs less salvage value = sum of totals expenses for 5 years
= 26,500 + 26,500 + 53,000 + 28,000 + 28,000
= $162,000.00
Finally, the sum of the yearly costs less salvage value is,
Total = total cost – salvage value
= 162,000– 0.00
= $162,000
Therefore, the sum of the yearly costs less salvage value for buy-alternative is “$162,000”.

= $76,380
For 3 year:
Payment for leased servers = Payment per unit × Servers leased
= 285 × 40
= 11400
Discount amount = Payment for leased servers × Discount
= 11400 × 0.10
= 1140
Total lease payment = (Payment for leased servers – Discount amount) × 12
= (11400 – 1140) × 12

About five years ago, Facebook was involved in a multimillion-dollar effort to move a terabyte of data from a near-capacity data center to a then new higher-capacity data warehouse. The project was scheduled to be completed in 100 days with no provision for any schedule delays. In Facebook terms, a terabyte is equivalent to 250 billion “Likes” on Facebook. The project had two phases, i.e., building and outfitting the new data warehouse, and then moving data to the warehouse. The new data warehouse was designed so the servers could handle four times as much data as the current servers, and the processors and software were upgraded as well. As a result, the new data warehouse could hold eight times more data than the current data center, and it could also move and manage data more efficiently. To reduce the risks the project team took a…arrow_forward
