One day I'm going to come back to this tweet and say "I made it in tech"

Cons: higher complexity, needs stateless design, load-balancing overhead, database sync challenges. In short: 🧱 Scale up for simplicity. 🌐 Scale out for resilience and long-term growth. #SystemDesign #Scalability #BackendEngineering #Architecture

Pros: simple setup, instant performance boost, great for non-distributed systems. Cons: single point of failure, expensive, limited by hardware/cloud caps. 🔹 Horizontal Scaling – Add more machines to share the load. Pros: fault-tolerant, nearly infinite scaling, cost-effective

🚀 DAY 3: Scalability Scalability is all about designing systems that grow as your users grow. It’s how you make sure performance and reliability keep up with demand. There are two main paths to scaling: 🔹 Vertical Scaling – Make one machine stronger (upgrade CPU, RAM, etc.)

Decide to cook up something for the backend community mind you that’s lovable I suck at frontend

3 prompts you don time me out till closing time, I no get 100 dollars o

TL;DR System Design is all about building systems that work at scale balancing performance, reliability, and maintainability. It involves both high-level architecture (how components fit together) and low-level design (how they’re implemented). #systemDesign #backenddevloper

3. Distributed Systems: Ensure applications are scalable, fault-tolerant, and maintainable especially when deployed across multiple servers or data centers. #architecturelovers #backendtools #SoftwareEngineering #softwareapplicationdevelopment

Core Areas That Shape System Design & Architecture 1. Operating Systems (OS): Manage system resources and processes that keep applications running efficiently. 2. Computer Networks: Enable communication between distributed machines and across different geographic locations.

It answers “How do all the parts fit together?” 2. Low-Level Design (LLD) This zooms into the implementation details defining classes, methods, data models, and structures. It answers “How is each component built internally?” #architecturelovers #backendtools

especially those that are data-intensive and operate at scale. Two Sides of System Design 1. High-Level Design (HLD) This focuses on the overall system architecture how major components like databases, APIs, caches, load balancers, and message queues connect and interact.

DAY 2 System Design is the process of defining the architecture, components, and interactions that enable a system to meet specific functional and performance goals. In simpler terms, it’s how engineers translate user requirements into scalable, maintainable, and reliable systems

Even though I’ve spent a good amount of time building microservice-based applications, I’ve come to realize that mastering System Design is essential to truly understanding scalability, resilience, and performance at scale. #SystemDesign #Backend #Microservices #SystemDesign

Just got a message from one of my mentees. She got promoted barely 2 months into the international job I recommended and is now earning over ₦2M monthly base salary. This is the same person who was earning ₦100k–₦200k from juggling multiple Nigerian companies doing the

A man in his 40s opens up about one of the hardest truths…

Next time you use Netflix, Amazon, or Uber, remember: behind the scenes is a symphony of machines acting as one.

Final Thought Distributed systems power the modern digital world but they’re not magic. They succeed because of careful design trade-offs between consistency, availability, performance, and fault tolerance.

10. Maintainability & Evolvability �� Systems must grow without chaos: Observability (logs, metrics, tracing). Automation (self-healing, CI/CD) Backward compatibility (smooth rolling upgrades).

8. Performance & Efficiency ⚡ Hide latency (async calls, caching). Optimize throughput (parallelism, sharding) Load balance workloads evenly. 9. Resource Management ��️ Scheduling jobs across nodes. Ensuring fairness. Isolation with containers/VMs.
