Rate limiting strategies: 1. Throttling levels: per-API key (1000 req/min), per-IP (100 req/min), global limits. 2. Rate limiting algorithms: token bucket, sliding window, fixed window approaches. 3. Burst handling: temporary burst allowance, graceful degradation during spikes. Authentication methods: 1. API key management: key rotation, expiration policies, usage analytics. 2. OAuth 2.0/JWT: token validation, scope-based authorization, refresh token handling. 3. mTLS: certificate-based authentication, client certificate validation. Security controls: 1. Input validation: request size limits (10MB), content type validation, schema enforcement. 2. WAF integration: SQL injection prevention, XSS protection, bot detection. 3. DDoS protection: rate limiting, IP blocking, geographic restrictions. Monitoring and analytics: 1. Request metrics: latency percentiles (P50, P95, P99), error rates, throughput tracking. 2. API usage: top consumers, endpoint popularity, quota utilization. Load balancing: upstream health checks, circuit breaker pattern, retry mechanisms with exponential backoff.

Automate server configuration and application deployment using Ansible for consistent, repeatable infrastructure management. Ansible architecture: 1. Control node: Ansible installation, inventory management, playbook execution. 2. Managed nodes: SSH access, Python installation, no agent required. 3. Inventory: static hosts file or dynamic inventory from cloud providers. 4. Modules: idempotent operations, return status (changed/ok/failed). Playbook structure: 1. YAML syntax: tasks, handlers, variables, templates, and roles organization. 2. Idempotency: tasks run multiple times with same result, state checking. 3. Error handling: failed_when, ignore_errors, rescue blocks for fault tolerance. 4. Variable precedence: group_vars, host_vars, extra_vars hierarchy. Role development: 1. Directory structure: tasks, handlers, templates, files, vars, defaults. 2. Reusability: parameterized roles, role dependencies, Galaxy integration. 3. Testing: molecule for role testing, kitchen for infrastructure testing. Configuration management: 1. Package management: ensure specific versions, security updates, dependency resolution. 2. Service management: start/stop services, enable on boot, configuration file deployment. 3. Security hardening: user management, firewall rules, SSH configuration, file permissions. Deployment strategies: rolling updates, blue-green deployments, canary releases with health checks every 30 seconds.

Optimize e-commerce fulfillment. Strategy: 1. Fulfillment model (in-house, 3PL, dropship). 2. Warehouse location optimization. 3. Order management system. 4. Picking and packing efficiency. 5. Shipping carrier negotiation. 6. Returns process streamlining. 7. International expansion (duties, compliance). 8. Peak season scaling. Use automation where possible. Focus on speed and accuracy. Customer experience crucial. Monitor fulfillment KPIs.

Implement NPS program. Process: 1. Survey timing (post-interaction or periodic). 2. Question: 'How likely to recommend 0-10?' 3. Categorize: Promoters (9-10), Passives (7-8), Detractors (0-6). 4. Calculate: %Promoters - %Detractors. 5. Follow-up questions for context. 6. Close the loop with respondents. 7. Root cause analysis. 8. Track trends over time. Use for customer sentiment. Benchmarks vary by industry. Focus on improving score by addressing detractors.

Systematically improve product performance and user experience. Performance metrics: 1. Core Web Vitals: Largest Contentful Paint (LCP <2.5s), First Input Delay (FID <100ms), Cumulative Layout Shift (CLS <0.1). 2. Time to First Byte (TTFB <600ms). 3. Time to Interactive (TTI <5s). 4. Application response times: API calls, database queries. Performance monitoring: 1. Real User Monitoring (RUM): actual user experience data. 2. Synthetic monitoring: automated performance tests. 3. Server monitoring: CPU, memory, disk usage. 4. CDN analytics: cache hit rates, edge performance. Optimization strategies: 1. Frontend: code splitting, lazy loading, image optimization, caching. 2. Backend: database query optimization, caching layers, microservices. 3. Infrastructure: CDN, load balancing, auto-scaling. Tools: Google PageSpeed Insights, New Relic, DataDog for monitoring. Performance budget: set thresholds, alert when exceeded, gate deployments on performance regression.

Build customer success playbooks. Components: 1. Onboarding playbook (30/60/90 days). 2. Adoption playbook (feature usage). 3. Expansion playbook (upsell triggers). 4. Renewal playbook (health scoring). 5. At-risk playbook (churn prevention). 6. Champion building playbook (advocacy). 7. Segmentation by customer tier. 8. Success metrics and activities. Document best practices. Scale CS team. Proactive not reactive. Tie CS to revenue outcomes.

Optimize retail merchandising. Strategies: 1. Product placement (eye level, end caps). 2. Planogram optimization. 3. Seasonal displays and themes. 4. Cross-merchandising complementary products. 5. Signage and pricing clarity. 6. Inventory visibility. 7. Store traffic flow design. 8. Impulse buy positioning. Use data on sales per square foot. Test and iterate layouts. Visual appeal matters. Balance bestsellers with discovery.
