Firecracker MicroVMs are lightweight virtual machines that provide OS-level isolation for serverless workloads. They offer blazing-fast boot times, minimal resource overhead, and enhanced security. In this deep dive, we'll explore how to tune kernel...

TL;DR * Ceph: Object storage on steroids with CRUSH algorithm * MooseFS: Lightweight and POSIX-compliant with a twist * JuiceFS: Cloud-native file system with a sprinkle of key-value store magic * All three systems offer unique approaches to replication,...

Multimodel databases combine different data paradigms (relational, document, graph, etc.) under one roof. We'll explore implementation patterns, query routing tricks, schema unification headaches, and how to deal with conflicting consistency models. Buckle up, it&...

TL;DR We'll dive deep into sophisticated invalidation strategies, explore event-driven approaches, flirt with "smart pointers" to data, wrestle with multi-layer caches, and navigate the treacherous waters of concurrency hazards. Buckle up,...

Server-Sent Events might sound like just another buzzword, but it's a technology that's been quietly revolutionizing real-time communication. Unlike WebSockets, which establish a full-duplex connection, SSE creates a unidirectional channel from the...

Before we dive into the how, let's quickly touch on the why: * Compliance: GDPR, CCPA, and friends don't take kindly to carelessly logged PII. * Security: Logs are often less secured than databases....

The world of Envoy and Kong, exploring advanced patterns for traffic management, security, and performance optimization. Expect to learn about multi-tenant routing, custom plugins, and how to implement a zero-trust architecture that would make even the...

We're combining the power of jsoniter, a blazing-fast JSON parser for Go, with AVX2 SIMD instructions to parse JSON at warp speed. Expect significant performance gains, especially for large datasets. The Need for Speed:...

Lua, born in the early '90s in the land of samba and football (that's Brazil for the geographically challenged), was once the darling of game developers. Its lightweight nature and ease of embedding...

Let's talk about why distributed sagas are the unsung heroes of microservice architectures. In a world where monoliths are so last season, managing transactions across multiple services can be a real headache. Enter distributed...

Reactive programming can be a powerful tool, but it's not without its pitfalls. From debugging nightmares to unexpected resource hogging, we'll explore when to embrace the reactive paradigm and when to run...

The TCP Tuning Tango Let's start with two lesser-known TCP options that can make a world of difference: tcp_notsent_lowat and TCP_CORK. These aren't your average configuration tweaks – they'...

What's the big deal with DIDs? Decentralized Identity is not just another buzzword in the tech industry. It's a paradigm shift in how we manage and control our digital identities. But before...

Why eBPF? Why Now? Before we dive in, let's address the elephant in the room: Why eBPF? Well, my fellow code wranglers, eBPF is like the Swiss Army knife of the kernel world (but...

The Problem: Distributed Transactions in Hotel Booking Let's break down our hotel booking system into its core components: * Reservation Service: Handles room availability and booking * Payment Service: Processes payments * Notification Service: Sends confirmation emails...
