We are building a small exchange and I am in charge of running the nodes with the proper configurations in order for our application to get all the proper info from the blockchain using our custom built API. I have installed a "small" node size on an m5.large at AWS and I'm having problem with the server usage. Even though its a large server it struggles a little and running a 32GB RAM server or 9 TB of storage would increase costs considerably. I was told Ripple runs its own servers, is it possible to connect via URL to these in order to not host our own node? We might consider creating an API using Ripple servers directly rather than running our own as running a full history ledger is about 9 TB. What other solutions could we apply in this case? Any help is greatly appreciated!
