json rpc – Methods to run Bitcoin Core as a manufacturing RPC Node?

I am planning to construct a pockets service with the next options:

• Question stability
• Question transaction historical past
• Ship transactions

I need to self-host a Bitcoin Core Node as my RPC Node. Since that is my first time working a Core Node in a manufacturing setting, I might prefer to ask:

1.Excessive Availability — Ought to I run a number of nodes for failover? What is the beneficial setup?

2.Monitoring & Sync — How do I monitor whether or not my node is correctly synced? Are there any beneficial instruments or metrics? Additionally, is block lag fully unacceptable for a pockets service, or is there a tolerable vary?

3.Basic finest practices — What does the group advocate for working a Bitcoin Core RPC Node in manufacturing?

Any recommendation or beneficial instruments can be appreciated. Thanks!
