Hi Artford,

Hi Availability (HA) is not related to Low Latency (LL). HA means if you have problem with one system eg database or EC2, there is a standby system “Available” that will fail over to it so that you can continue to work without disruption, hence the term high availability. HA means having a redundant system like your spare tyre in the boot of your car in case you have a punctured tyre, you can switchover to the spare tyre to continue your journey. But Low Latency means high speed system that completes within a short (low) time. This is good, but High Latency is not good as it means a slow system that completes in long (high) time.
