But to fix them, developers should know when a certain bug appears, and the context of the bug. To get this first-hand information, we set up monitoring services, which monitor the health of the […]
Read MoreWelcome to the second and last part of the series Consistent Hashing for Distributed Cache Systems. In our previous article, we first established what a Distributed Cache system is and what we use Distributed hashing for. We also saw a sample usage of distributed hashing. We then saw the problem of rehashing and highlighted the […]
Read MoreConsistent Hashing for Distributed Cache Systems, the topic itself seems to be very heavy and confusing. Before jumping on to the article, let us break down the topic into simple terms and draw a conclusion on what this article aims to achieve. This is part-1 of the series in which build the intuition as to […]

Read MoreIn our last post, we got to know about the concept and significance of resilient systems. We also studied the concept of circuit breakers, with a great deal of theoretical explanations and standardizations. This post is going to get a little deeper into the execution phase, wherein we discuss the issues we need to cater […]
Read MoreA system being an isolated, independent entity is a scarce thing. They do have dependencies, dependencies on other systems. A very classical example is Database.
