Cloud4Y explains that […]
The infrastructure of a modern metropolis is built on Internet of Things devices: from cameras on the roads to large hydropower plants and hospitals. Hackers can turn any connected device into a bot and further use it to carry out DDoS attacks. The motives can vary widely: hackers may be paid by governments or corporations, or sometimes it's just criminals looking to have fun and make money. In […]

For this task, Tarantool has a module written in Lua called expirationd. After a short period of using this module, we realized it was not suitable for us: […]
