justalock
Distributed locks, zero setup required.A distributed lock is used to ensure that if one actor is using a shared resource, no other actor will use that resource. Locking is an important mechanism in distributed systems to prevent multiple actors from updating a single piece of data at the same time (and possibly corrupting the data in the process).
justalock provides publicly available locks on demand.Try It Now
