Six Real-World Enterprise Use Cases of INFINI Gateway for Elasticsearch

Scenario 1: Zero‑Cost Elasticsearch Security Framework

Problem background

A historical project used Elasticsearch 6.7 without an X‑Pack license due to budget constraints and later suffered security vulnerabilities, requiring authentication and authorization mechanisms.

Traditional solution challenges

Manual configuration of basic security modules is complex.

Open‑source alternatives such as Search Guard pose compatibility risks.

Upgrading the cluster version incurs huge cost.

INFINI Gateway solution

INFINI Gateway provides three security mechanisms:

Basic authentication: the gateway intercepts unauthorized requests.

IP whitelist: only allows specific internal network segments.

TLS termination: expose HTTPS on port 443.

Scenario 2: Intelligent Defense Against Abnormal Query Attacks

Problem manifestation

A DSL query of 100,000 characters caused the cluster CPU to spike to 100% and nodes to OOM.

Gateway defense strategy

Three‑layer protection:

DSL length limit: reject requests exceeding 5 KB.

JSON parsing depth control: prevent deep‑nesting attacks.

Regex filtering: block malicious script statements.

Scenario 3: Automated Circuit Breaking for Slow Queries

Operational pain point

When cluster load is high, the native Elasticsearch API _cat/tasks times out, making manual intervention inefficient.

Smart circuit‑break configuration

Mechanism:

Real‑time monitoring of query execution time.

Automatic trigger of circuit break when execution exceeds 30 seconds.

Asynchronous notification system records slow‑query logs.

Scenario 4: High‑Performance Proxy Architecture Practice

Drawbacks of traditional Nginx reverse proxy

Cannot understand Elasticsearch protocol semantics.

Lacks DSL‑level filtering capability.

Weak cluster state awareness.

Advantages of INFINI Gateway as proxy

Provides seamless compatibility with all Elasticsearch versions, integrates without code changes, and offers built‑in traffic analysis and control.

Scenario 5: Fine‑Grained Read/Write Traffic Control

Rate‑limiting requirements analysis

Write bursts cause indexing blockage.

Complex aggregations consume large resources.

Different business lines need differentiated QPS control.

Three‑dimensional throttling configuration

Index‑level: limit write rate per index pattern.

User‑level: control query frequency for specific accounts.

Operation‑type: distinguish search, index, bulk actions.

Scenario 6: End‑to‑End Log Tracing

Native Elasticsearch shortcomings

Audit requires X‑Pack commercial edition.

Lacks correlation analysis capability.

Gateway audit information dimensions

Basic info: timestamp, client IP.

Operation details: index name, DSL summary, query type.

System metrics: response time, resource consumption, shard distribution.

Conclusion: Why Choose INFINI Gateway?

INFINI Gateway acts as a dedicated intelligent proxy for Elasticsearch, Easysearch, OpenSearch, and similar systems, offering zero‑intrusion, high performance, and low cost. It resolves security, performance, and operational pain points of native open‑source Elasticsearch, making it suitable for budget‑constrained enterprises that need production‑grade reliability.
