But what if multiple applications are running on the same infrastructure? How can we ensure each one has the minimally required resources? How can we restrict resource consumption?

Unfortunately, this term does not have a good English equivalent. Wikipedia translates it as 'multitenancy'. Sometimes it is referred to as 'multiple ownership'.

And it happened on the right side of the spread, which is very inconvenient. This means that if Vasya needs to write the next batch of his thoughts while having the previous step in front of him, he will have to scroll the sheet of paper […]

Hello everyone. We are actively getting to work and already preparing many powerful launches in January. Among other things, we are announcing the enrollment for a new cohort of the popular ‘Linux Administrator’ course. In anticipation of the launch, we traditionally share a translation of useful material. File permissions provide a secure alternative to SUID executable files, but they may seem a bit confusing at first glance. We all know that […]
Readers are invited to familiarize themselves with the principles of building a fault-tolerant infrastructure for a small enterprise within a single data center, which will be discussed in detail in a series of articles.
