System Design Solution

SystemDesign Solution
For a Read-Heavy SystemConsider using a Cache.
For a Write-Heavy SystemUse Message Queues for async processing
For a Low Latency RequirementConsider using a Cache and CDN.
Need 𝐀tomicity, 𝐂onsistency, 𝐈solation, 𝐃urability Compliant DBGo for RDBMS/SQL Database.
Have unstructured dataGo for NoSQL Database.
Have Complex Data (Videos, Images, Files)Go for Blob/Object storage.
Complex Pre-computationUse Message Queue & Cache.
High-Volume Data SearchConsider search index, tries or search engine.
Scaling SQL DatabaseImplement Database Sharding.
High Availability, Performance, & ThroughputUse a Load Balancer.
Global Data DeliveryConsider using a CDN.
Graph Data (data with nodes, edges, and relationships)Utilize Graph Database.
Scaling Various ComponentsImplement Horizontal Scaling.
High-Performing Database QueriesUse Database Indexes.
Bulk Job ProcessingConsider Batch Processing & Message Queues.
Server Load Management & Preventing DOS AttacksUse a Rate Limiter.
Microservices ArchitectureUse an API Gateway.
For Single Point of FailureImplement Redundancy.
For Fault-Tolerance and DurabilityImplement Data Replication.
For User-to-User fast communicationUse Websockets.
Failure Detection in Distributed SystemsImplement a Heartbeat.
Data IntegrityUse Checksum Algorithm.
Efficient Server ScalingImplement Consistent Hashing.
Decentralized Data TransferConsider Gossip Protocol.
Location-Based FunctionalityUse Quadtree, Geohash, etc.
Avoid Specific Technology NamesUse generic terms.
High Availability and Consistency Trade-OffEventual Consistency.
For IP resolution & Domain Name QueryMention DNS.
Handling Large Data in Network RequestsImplement Pagination.
Cache Eviction PolicyPreferred is LRU (Least Recently Used) Cache.
To handle traffic spikesImplement Autoscaling to manage resources dynamically
Need analytics and audit trailsConsider using data lakes or append-only databases
Handling Large-Scale Simultaneous ConnectionsUse Connection Pooling and consider using Protobuf to minimize data payload
To prevent overloading systemsUse Token Bucket and Leaky bucket Algorithms
Minimize deployment downtimeImplement Blue-Green deployment to minimize downtime and reduce risks

Forward Proxy vs. Reverse Proxy
