OCI Network Load Balancer (L4)
Low-latency pass-through NLB with TCP/UDP listeners, backend health checks and preserved client IPs.
Verification
Plan-validatedPassed: module logic verified on a mocked plan - inputs, validation rules, conditional creation and outputs resolve (no real provider, no cloud).
Conformance
- Static validation (fmt · validate · tflint)
- Security scan clean (Checkov)
- Plan tests (mocked: validation rules · outputs)
Provenance
- SHA-256 checksum
- Cosign signature
Functional
- Live test pending (no cloud run yet)

Documentation
oci-network-load-balancer
Status: static-validated, live-test pending. Ships under live-test quarantine — no OCI cloud sandbox is wired into CI yet, so the live apply → verify → destroy gate has not run. Static validation (fmt, validate, tflint) passes.
Low-latency, pass-through Layer-4 Network Load Balancer for OCI: TCP/UDP
listeners, backend sets with L4 health checks, and preserved client source
IPs. Simpler and cheaper than the L7 Load Balancer — the natural front door for
OKE node pools, custom TCP services and UDP workloads. Works with Terraform
and OpenTofu (>= 1.6), OCI provider >= 8.0, < 9.0.
Secure defaults
- Private by default (
is_private = true): no public IP unless you opt in. - Deny-by-default backends: a backend only receives traffic once it passes its health check; health checks are required on every backend set.
- NSG-first: attach
network_security_group_idsfor a stateful, deny-by-default data plane instead of opening the subnet security list. - Client-IP preservation is available per backend set (
is_preserve_source) and NLB-wide (preserve_source_destination) for transparent backends. - A reserved public IP can only bind to a public NLB (precondition), and symmetric hashing requires source/destination preservation (precondition).
Requirements
- Terraform or OpenTofu
>= 1.6 - Provider
oracle/oci>= 8.0, < 9.0

oci-load-balancer
HTTPS load balancer with backend sets, health checks, TLS certificates, rule sets and WAF-ready listeners.
tencent-clb
A listener's health check is a switch that, off, sends traffic to every target forever; a port-80 listener forwards unless a redirection resource points it at 443; and delete_protect defaults to false. HTTP health checks on a path through listener rules, a 301 from 80 to 443 whenever a certificate is given, deletion protection on, access logs when a CLS topic is given.
huawei-elb
The default TLS policy accepts TLS 1.0; a pool without a monitor resource is never unhealthy and sends traffic to every member forever; an HTTPS listener does nothing about port 80 until an L7 policy redirects it; and deletion protection is off. tls-1-2-strict, an HTTP monitor on a path, a redirect on 80 whenever a certificate is given, two zones unless one is accepted, deletion protection on.
vultr-load-balancer
The default health check is TCP on the backend port, which a process that stopped serving still passes; ssl_redirect defaults to false, so the site stays in clear on 80; and a balancer with no instances is a public address that fails. HTTP checks on a path, redirect on whenever HTTPS exists, backends required, and a Let's Encrypt certificate from auto_ssl_domain rather than a pasted key in state.
do-load-balancer
The default health check is a TCP handshake, which a process that stopped serving still passes; redirect_http_to_https defaults to false, so the site stays in clear on 80; and a balancer with no tag and no droplets is a public address that 503s. HTTP checks on a path, redirect on whenever HTTPS exists, STRONG ciphers, backends required, and a Let's Encrypt certificate made from your domains.
upcloud-load-balancer
The backend health check defaults to TCP, which a process that stopped serving still passes; TLS is a certificate bundle nobody creates; a port-80 frontend forwards unless a rule redirects it; and a public network puts the frontend on the internet. HTTP checks on a path (TCP by name), a Let's Encrypt bundle for the hostnames you list, a 301 from 80 whenever it exists, and public by name.
