OverviewIn distributed systems, there are scenarios that require the use of a globally unique ID, which can be used to prevent ID collisions using a 36-bit UUID, but the UUID has some drawbacks, first he is relatively long, and the UUID is generally unordered.There are times when we want to use a simple ID and want the ID to be generated in an orderly fashion.The snowflake of Twitter solved this demand, and initially Twitter migrated the storage syste

Firewalls are the core and increasingly complex part of network security, and are constantly fighting against the ever-changing threats faced by enterprises. The updated firewall can analyze network traffic behavior, protocols, and application layer data. However, when resources are transferred to Amazon cloud, enterprises may find that there are no firewalls of the same quantity and type available. In this article, we will investigate the built-in firewalls, third-party firewalls, and open-sour

The snowflake algorithm is particularly efficient when generating IDs, for reference to: 1190000011282426The result of the snowflake algorithm generation ID is an integer of 64bit size, which is structured as: 1位No. The highest 1 of the binary is negative, but the IDs we generate are usually integers, so this is 0. 41位, which is used to record the timestamp (in milliseconds). 41-bit can repre
