Start with understanding single server limitations, identify bottlenecks (CPU, memory, disk I/O), then make informed decisions about vertical vs horizontal scaling. Database optimization is often the real bottleneck, not application servers. Load balancers require careful algorithm selection and configuration. Even redundant architectures have single points of failure that need identification and mitigation. The key is adding complexity only when necessary and understanding the tradeoffs at each step. ## Full article daily.dev links to this article rather than hosting it.

Poor database design will make you scale the application server, yet your app is not getting any faster **@micahnorwoodjordan** · 2 upvotes > system design definitely pushes you into senior levels of problem solving. it's dreadful seeing what happens when an app goes down and it becomes "all hands on deck" while the team tries to resuscitate it, but cant because of the poor planning and architecting behind the app **@akhlaqurrahmanomi** · 0 upvotes > Interesting read **@angus\_hhz** · 0 upvotes > I like your article . Would you mind if i ask name website using to draw system design above. **@publicaccount** · 0 upvotes > I really enjoyed man ! may your all endeavors be fruitful ! ## Similar posts on daily.dev - [How to Scale a System from 0 to 10 million\+ Users](https://daily.dev/posts/how-to-scale-a-system-from-0-to-10-million-users-ytm2sqndw) · Hacker News · 2 upvotes · 0 comments --- Tags: [#career](https://daily.dev/tags/career), [#database](https://daily.dev/tags/database), [#architecture](https://daily.dev/tags/architecture) [View this post on daily.dev](https://daily.dev/posts/how-to-scale-like-a-senior-engineer-servers-dbs-lbs-spofs--dgn2e1t7w) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How to Scale Like a Senior Engineer (Servers, DBs, LBs, SPOFs)","url":"https://daily.dev/posts/how-to-scale-like-a-senior-engineer-servers-dbs-lbs-spofs--dgn2e1t7w","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-to-scale-like-a-senior-engineer-servers-dbs-lbs-spofs--dgn2e1t7w"},"datePublished":"2025-10-15T18:12:23.426Z","dateModified":"2025-10-15T18:12:45.401Z","description":"Scaling systems is about solving problems incrementally, not jumping to complex solutions.
