Clarification:

Can you pls let me know what manage means? Does it mean hosting the storage, enrolling new citizens, providing adminstration and technology support? Yes
Is it intended to offer only for 3 years starting from this year or 3 years for every citizen in their life or want to estimate cost only for 3 years but given free life time? Later

The source of cost are below.

Storage cost
Networking Cost
Manpower cost (administration & Technology support

User and Needs

0-6Yrs no need for storage and they dont operate electronic devices
7-18 Years for storing education and cartoon material
18-60 Years to store personal videos
60+ years for storing personal videos

Solution

As the storage is for all and lets assume population growth of 5% and inflation of 2%


Age	Need	Mobile Size (GB)	Laptop (GB)	Age group	Total Size (MillionGB)
0-6 Yrs	0	0	0	10%	-
7-18Yrs	Education	20	60	20%	4,800
18-60Yrs	Hobby	60	200	40%	31,200
60+	Hobby	40	100	30%	12,600
					48,600

Based on this total storage required in Yr 1 is 48.6MillionTB. Government may choose to go for a distaster recorvery that will provision 50% of additional data.

Hence total storage in a day = 72.9Million TB

Per TB storage cost per year = 50$

Inflation= 2%

Growth in population 5% and equal in all segments and constant for 3 years.

	Storage Million TB	Cost ($)
Yr 1	48.6	50
Yr 2	51.03	51
Yr 3	53.58	52
Total cost in Mn$		7820

Total 3 Yrs storage cost=$7.82 B

Total cost including networking and applications (Assuming netwrking and updation of applications in servers is 10% of storage cost)= 7.82X1.1=$8.6B

Manpower cost:

Assuming 3 scrum teams (25 people) required to maintain and update servers and resolve any problems, Total Years cost = $0.2MX 25= $5M=$0.005B (Does not impact the total cost)

So total cost of 3 years operation is $8.6B

Program composition:

1 Scrum team to manage the storage
1 scrum team to resolve customer problems at back end
1 scrum team taking customer grievances and managers to manage the team
