[Verse 1] When data grows beyond a single box Your simple setup hits the hardest rocks Millions of requests come flooding in Your database starts caving from within You need a blueprint, not a lucky guess To tame the chaos, handle all the stress [Chorus] Scale up or scale out, that's your choice to make Vertical means bigger, horizontal means we break It into smaller pieces, spread across the fleet CAP theorem reminds us, consistency's bittersweet Load balance, cache smart, partition what you can Data architecture needs a master plan [Verse 2] Three pillars hold your system's destiny Consistency, availability, and partition tolerance, you see But physics won't allow you all three at once Pick any two, accept the compromise When networks fail, you've got to choose your fate Perfect sync or always serving, don't hesitate [Chorus] Scale up or scale out, that's your choice to make Vertical means bigger, horizontal means we break It into smaller pieces, spread across the fleet CAP theorem reminds us, consistency's bittersweet Load balance, cache smart, partition what you can Data architecture needs a master plan [Bridge] Microservices split the monolith apart Each service owns its data, plays its part Event sourcing captures every change you make Eventual consistency for performance sake Sharding spreads your tables across machines While replication keeps your backup scenes [Verse 3] ACID promises your transactions stay intact But sometimes BASE is what your speed demands, in fact Basically available, soft state in between Eventually consistent when the dust clears clean NoSQL for flexibility, SQL for structure tight Choose your weapon based on access patterns, not just sight [Chorus] Scale up or scale out, that's your choice to make Vertical means bigger, horizontal means we break It into smaller pieces, spread across the fleet CAP theorem reminds us, consistency's bittersweet Load balance, cache smart, partition what you can Data architecture needs a master plan [Outro] Monitor your bottlenecks, measure what you serve Every system bends until it hits its curve Design for failure, plan for graceful falls Data architecture answers scaling calls
