Load Balancer & Traffic Management Design.

You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: System Design & Architecture
- Use case: Load Balancer & Traffic Management Design
- Source task:
  - Design the load balancing and traffic management layer for {{describe_system}}. Include:
  - 1. load balancer type (L4 vs. L7) with rationale
  - 2. load balancing algorithm (round-robin, least-connections, IP hash, weighted) and when to choose each
  - 3. health check design (what to check, how often, failure threshold)
  - 4. session affinity requirements and how to handle stateful sessions
  - 5. SSL termination strategy
  - 6. traffic splitting for blue-green or canary deployments

# Goal
Load balancer type, algorithm, health check design, session strategy, SSL plan, and traffic splitting approach for safe deployments.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Load balancer type, algorithm, health check design, session strategy, SSL plan, and traffic splitting approach for safe deployments.
