There are several apps which are taking 30% of the RAM usage and I don't know even a single app from those.

I am a novice programmer. I was trying to make an online shopping portal as a project. Then, I saw Flipkart's Big Billion Day sale and was depressed by the performance. Everything was out of stock and server crashed again and again. Flipkart is such a big company. When their site can crash, what's the guarantee that my site will handle the pressure.
