Hello, Habr. For future students of the "Highload Architect" course we prepared a translation of the material.
We also invite you to register for an open webinar on the topic "Replication as a Pattern of Storage Scale- Out " with Vladislav Rodin (Team Leader and Java Enterprise Development Specialist). In this lesson, participants will walk through replication, one of the database scaling techniques.
I have several microservices that communicate with each other using JSON over REST, and it seems to me that soon they will reach the VPS performance limit, and I will need to upgrade it so that there is no performance drawdown.
