Load Balancing

Traffic distribution, health checks, and TLS termination for resilient entry points.

Load balancing design and implementation for application and network entry points: health-checked backends, TLS termination, session considerations, and drain-friendly deploys. We tune for the failure modes you actually see—not generic textbook topologies.

Who it’s for

  • Teams exposing services behind a single host today
  • Platform groups standardizing ingress patterns
  • Ops teams improving deploy safety with connection draining

Problems we address

  • Traffic hits one server with no health-aware routing
  • TLS and routing rules are undocumented
  • Deploys drop connections because draining was never configured

Expected outcomes

  • Load balancer or reverse proxy topology with health checks
  • TLS and routing configuration as code where practical
  • Deploy-friendly drain and deregistration patterns

Timeline depends on scope, access, and dependencies—not a delivery guarantee.

Process

A clear delivery path from discovery through handover and optional support.

  1. 01

    Discovery

    Goals, constraints, success criteria, and current-state review.

  2. 02

    Architecture

    Target design, interfaces, risks, and delivery sequence.

  3. 03

    Implementation

    Incremental build with visible progress and documented decisions.

  4. 04

    Testing

    Functional checks, failure paths, and acceptance criteria validation.

  5. 05

    Deployment

    Controlled release to staging and production with rollback paths.

  6. 06

    Handover

    Runbooks, access notes, and operator/admin walkthrough.

  7. 07

    Support

    Optional hypercare window or retainer continuity after go-live.

FAQ

Cloud LBs reduce undifferentiated ops for many teams. Self-managed proxies still make sense for specialized routing, telephony edges, or constrained environments.

We can design DNS and multi-region entry patterns when that is in scope. Global traffic management is a deliberate architecture choice, not a default add-on.
