Answer 1

Try:

• Zoo Keeper https://dzone.com/articles/distributed-lock-using
• Hashicorp Consul https://www.consul.io/docs/guides/semaphore.html
• Azure Blobs have a lease feature that can be used https://learn.microsoft.com/en-us/azure/architecture/patterns/leader-election
• Etcd
• Any relational database. With the correct use of row locks to guarantee linearizable writes to a row you can create a distributed lock.

There are surely many more.
