Nour

System design interviews are broken. You memorise diagrams. You regurgitate patterns. You get the job. Then prod goes down and you freeze — because you’ve never actually watched a system fail. I built Cascode to fix that. It’s a browser canvas where you wire up real AWS architectures, watch messages flow through them live, then start killing nodes. See what cascades. Understand why. No cloud account. No setup. Just you breaking things on purpose — before production does it for you. → 10 built-in challenges → 10 AWS services → AI architecture review (with a letter grade) → Terraform export when you’re ready to ship → Shareable links for your team cascode.uk What’s the worst system failure you’ve ever caused? 👇

@VictorKildahl Thanks! Definitely.

@mxnyapps Cool project Nour, lets connect!

This post connected me with a ton of awesome people 🤯 Met so many builders working on cool stuff in tech, SaaS, and AI. Let’s keep it going - always looking to connect with more people building interesting things 👻 What are you working on right now?

Proud to have launched on @ProductHunt Check it out 👇🏼💻 producthunt.com/posts/cascode

@shub0414 You can practice by simulating them on Cascode.uk for free!

☁️ AWS in Plain English (so you are never feel lost again): • EC2 → your computer in the cloud • S3 → a giant unlimited folder • RDS → a managed SQL database • Lambda → code that runs automatically • API Gateway → doorway to your APIs • CloudWatch → logs + monitoring • VPC → your private network • IAM → security guard of AWS • CloudFront → global CDN for speed • DynamoDB → NoSQL database • SNS → sends notifications • SQS → message queue that never sleeps Master these → 80% of AWS suddenly becomes simple. Hope this helps.

𝗬𝗼𝘂 𝗱𝗼𝗻'𝘁 𝗵𝗮𝘃𝗲 𝗮𝗻 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺. 𝗬𝗼𝘂 𝗵𝗮𝘃𝗲 𝗮 𝘀𝘁𝗮𝗴𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺. What I've seen in my career is that most teams pick architecture based on hype, not real needs. They see how Netflix runs microservices and assume that's the answer. A 5-person startup running microservices isn't engineering. It's cosplaying. Here's what you need to know about each one: 𝗠𝗼𝗻𝗼𝗹𝗶𝘁𝗵 → You're still figuring out what to build. A monolith lets you move fast, refactor easily, and deploy one thing. Start here, especially if you're a startup. And make it modular. 𝗠𝗶𝗰𝗿𝗼𝘀𝗲𝗿𝘃𝗶𝗰𝗲𝘀 → Multiple teams stepping on each other. Deployments take hours. One bad change breaks everything. That's when you split, and only along real team boundaries. If you can't afford a platform team, you can't afford microservices. 𝗦𝗲𝗿𝘃𝗲𝗿𝗹𝗲𝘀𝘀 → You want to stop managing infrastructure for workloads that don't need it. Works well until vendor lock-in creeps in. By the time you notice, migration costs are enormous. A well-structured (modular) monolith beats poorly designed microservices every time. You can mix them too. Monolith core with serverless for specific workloads is often the right call. Stop choosing architecture for where you want to be. Choose it for where you are.
