One of the problems that we come up against when designing scalable & highly available systems is how can we partition and replicate data in our systems. Data partitioning is the process of distributing data across a set of nodes while Data Replicati...
In distributed systems, failures will occur, e.g., servers can crash, disks can go bad resulting in data losses, or network connection can be lost, making a part of the system inaccessible. How can a distributed system model itself to get the maximum...
In this blog post we I will talk about some key characteristics of a highly scalable distributed system in particular: Scalability Read Part 4 Reliability Availability Efficiency and Manageability. Scalability Scalability is the capability of a sys...
In this Blog post I am going to talk about some low level OS concepts (CPU modes, Protection Rings, etc). It is very unlikely that you will ever work on an operating system core. However, your software is always influenced by operating systems work a...
In order to understand how the the concept of cloud [unlimited computing resourcing] works, we need to understand the concepts of scalability. In other words how does computing resources scale ? Let's consider the basic simple web application softwar...
So you have developed your backend for your application that you want to serve multiple users. Users will send you requests using their front end applications that are either installed on their mobile phones or that is living in their browsers and yo...
