Currently, publicly available wifi hotspots are the preferred networks for video consumption, but poor network infrastructure also leads to unbearable video buffering and latency. However, OTT streaming delivery requires something faster than what the internet offers in terms of how chunks/fragments are supposed to flow.

The new Amazon capability enables customers to improve the startup latency of their functions from several seconds to as low as sub-second (up to 10 times faster) at P99 (the 99th latency percentile). This can cause latency outliers and may lead to a poor end-user experience for latency-sensitive applications.

In PACELC terms we choose PC/EC and have the same level of availability for writes of our previous system while improving our theoretical availability for reads.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
