Need help to understand more about Social media app Services & Storage expanse.

Hi Guys,

Need help to understand more about Social media mobile application running expanse. (Storage, services)

We are building a social media mobile application and while working on valuation, I calculated the expenses of running the system. (I'm calculating this for India Region)

But I have some doubts regarding the dynamic storage, seems I’m not doing it right. Can you guys help me to find a possible number?

below I’m sharing the per year user & their average storage.

1. What do you think about Static storage? For now, I’m exploring AWS EC2.
2. What do you think about Dynamic storage? For now, I’m exploring AWS S3.
3. What’s the best way to calculate the pricing for Dynamic storage? Assume below is 5-year user & per-user storage data.
4. Let me know if i'm missing anything.

• 1st year, 10000 user & 1 GB per user.
• 2nd year, 30000 user & 1.5 GB per user.
• 3rd year, 100000 user & 1.8 GB per user.
• 4th year, 35000 user & 2 GB per user.
• 5th year, 1200000 user & 2.5 GB per user.
