Architectural Knowledge Base & Engineering FAQs
Comprehensive reference guides on cloud tariffs, edge execution isolates, vector similarity search, and high-availability database replication.
How are Cloud Egress Tariffs Calculated?
Egress tariffs occur when data leaves a provider's private network out to the open internet or another cloud region. Hyperscalers like AWS and GCP charge up to $0.09–$0.12/GB. Modern edge platforms (Cloudflare R2, Wasabi, Hetzner) offer zero egress fees or massive monthly transfer quotas (20TB+), eliminating network bandwidth surprises.
What Causes Serverless Cold Start Latency?
A cold start occurs when an idle serverless instance initializes a fresh container runtime to handle an incoming HTTP request. While Chrome V8 isolates (Cloudflare Workers) achieve near 0ms cold starts, full Docker microVM containers (AWS Lambda, Google Cloud Run) average 100ms to 500ms depending on binary bundle sizes.
Managed Vector DBs vs. pgvector: Which is Best?
Dedicated vector stores (Pinecone, Qdrant) excel at multi-million vector indexing with specialized HNSW retrieval algorithms. However, using pgvector on Supabase or Neon lets developers run relational SQL queries and vector similarity searches in a single database, eliminating complex cross-database synchronization.
Chrome V8 Isolates vs. Firecracker MicroVMs
Chrome V8 isolates isolate execution environments at the JavaScript/Wasm runtime level inside a shared OS process, consuming minimal RAM (~5MB). Firecracker microVMs create hardware-virtualized minimal Linux kernels for every workload, offering total OS isolation and broad language runtime compatibility at the cost of slight memory overhead.
How to Avoid Proprietary Vendor Lock-in?
High vendor lock-in occurs when using proprietary APIs (DynamoDB, BigQuery, AWS SQS). To maintain full architecture portability, build applications using open standards: standard PostgreSQL, S3-compatible object storage APIs, and OCI-compliant Docker containers deployable across any PaaS or bare-metal VPS.
What is Cloud Egress Bandwidth Arbitrage?
Bandwidth arbitrage is an architectural strategy where origin data stored in standard cloud platforms is fronted by zero-egress networks (e.g., Cloudflare R2, Wasabi, or Akamai Linode) via CDN alliances. This routes user traffic away from high-cost hyperscaler egress points, lowering bandwidth costs by up to 90%.
How Does Serverless Database Connection Pooling Work?
Stateless serverless functions can quickly exhaust PostgreSQL connections because each invocation opens a separate connection. Dedicated proxies like PgBouncer, Supabase Pooler, or Prisma Accelerate maintain a persistent pool of TCP connections to the database, allowing thousands of transient edge requests to share a minimal number of active database sockets.
What are Object Storage Cold and Archival Tiers?
Cold storage tiers (such as AWS S3 Glacier or Google Cloud Coldline) reduce raw storage fees down to ~$0.001–$0.004/GB per month. While hot storage provides millisecond retrieval times, archival tiers require retrieval initiation times ranging from minutes to hours, making them optimal for disaster recovery backups and regulatory compliance archives.
