About the technology

What is OpenSearch?

OpenSearch is an open-source search and analytics engine under the Apache 2.0 licence. It supports full-text, log and vector search as well as dashboards; security, scaling and operational capabilities are verified for the selected version.

We support the installation, configuration and optimisation of OpenSearch clusters for log analytics, full-text search, observability and semantic AI search. Architecture, performance and cost are aligned with the actual data and query profile.

OpenSearch Features

  • Full-Text & Semantic Search

    Powerful lexical full-text search with BM25 algorithm combined with semantic k-NN search for precise search results in large datasets.

  • AI-Powered Vector Search

    State-of-the-art AI vector search with Facebook FAISS integration, SIMD hardware acceleration, and quantization for high-performance semantic search and RAG applications.

  • Enterprise Security

    Comprehensive security features with RBAC, TLS encryption, audit logging, fine-grained access management, and support for LDAP, SAML, OpenID Connect - completely free.

  • Observability & Monitoring

    Trace Analytics, Event Analytics, Operational Panels, and Metrics Analytics with OTLP support for comprehensive monitoring of logs, traces, and metrics.

  • OpenSearch Dashboards

    Powerful visualization dashboards as Kibana alternative with Event Analytics, Notebooks, Piped Processing Language, and flexible visualization options.

  • Horizontal Scalability

    Remote-backed storage and cluster sharding can support large data volumes. Sizing and sustainable scale are tested against data volume, query patterns and recovery targets.

  • Log & Trace Analytics

    Advanced log analysis, trace analytics, and correlation across logs, traces, and metrics for deep insights into your systems.

  • High-Performance Queries

    Query and ingestion performance is tested against data volume, shard strategy, replication and real search profiles, then optimised for the workload.

  • RESTful API & Integrations

    Extensive RESTful API, plugin ecosystem, integration with AI services, and compatibility with Elasticsearch clients for seamless migration and flexible extensions.

Infrastructure, integration and operations

OpenSearch as part of your infrastructure

We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.

Architecture and migration

Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.

  • On-Premise

    In your data center: Installation on bare-metal, VM or Docker · Integration with existing Active Directory/LDAP

  • Installation in your cloud

    In your own cloud account, for example with AWS, Azure, GCP or Hetzner · Terraform/IaC setup (optional) · Kubernetes or Docker Compose · Capacity and scaling design

  • Enterprise Setup

    Advanced architecture after technical and licence assessment: HA and recovery design where supported by the application and edition · Logging according to feature set and edition · Custom security policies

Network and identity

SSO, secure access, internal systems and existing security components are integrated appropriately.

  • VPN Access

    WireGuard, NetBird, Tailscale, Headscale, OpenVPN, Cloudflare Tunnel · Easy client setup for all devices

  • SSO Integration

    Directly or through an upstream identity layer

  • Multi-Factor Auth

    Depends on application, edition and identity provider

  • Firewall & Hardening

    Fail2Ban, Rate Limiting, IP Whitelisting

Monitoring and service level

Updates, backups, technical monitoring and response paths follow a transparent operational scope.

  • 24/7 proactive monitoring

  • Updates and patches

    Regular updates, CVE monitoring and prioritised patches for critical vulnerabilities

  • Daily backup with 7-day retention

  • Personal technical contact

Integration and development

APIs, automation and custom extensions can be delivered beyond basic deployment.

  • Search Pipelines

    Manipulation of queries before execution. We develop request processors that enrich synonyms, correct typos, or analyze user intent.

  • Ingest Pipelines

    ETL directly in the cluster. We write ingest processors that enrich documents upon indexing (GeoIP, NLP sentiment, PII masking).

  • Vector Search (k-NN)

    Implementation of semantic search via k-NN plugin. We connect OpenSearch with embedding models for RAG applications.

Full-service installation with no hidden costs

What the OpenSearch setup includes

  • Complete installation & configuration
  • SSL certificate & reverse proxy setup
  • Backup strategy & disaster recovery
  • Performance optimization & tuning
  • Security hardening following OWASP
  • Monitoring & logging setup
  • Documentation & best practices
  • Administrator training (remote)
  • 30 days email support included
  • Dedicated contact person
  • Optional integration: LDAP/AD, SSO, MFA
  • Update strategy & patch management setup

The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.

Concrete Use Cases

OpenSearch Development & Integration

Search is more than `SELECT *`. We optimize OpenSearch for relevance, performance, and AI-powered vector search.

RAG Knowledge Base

Problem

LLMs hallucinate without context. Vector databases are complex to manage.

Solution

OpenSearch as hybrid search store (keyword + vector). Optimized retrieval queries for precise LLM answers.

E-Commerce Search Tuning

Problem

Customers don't find products when they misspell technical terms or part numbers.

Solution

Custom N-Gram tokenizers and phonetic analysis that finds 'screwdriver' even with dialect/typos.

Target architecture

Integrate OpenSearch into your infrastructure with clear controls

Data platforms are designed around access patterns, consistency, growth, recovery and the applications that depend on them.

Applications and data sources

Defined clients, services and ingestion processes connect through private or secured interfaces.

Secure access

TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.

Identity and permissions

Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.

OpenSearch platform

Queries, indexes, roles, resource limits and maintenance processes are configured for the workload.

Persistence and I/O

Storage class, capacity, latency and growth aligned with the data profile.

Replication and availability

Optional cluster, replica or failover design according to the required protection objective.

Backup and recovery

Consistent backups, retention and scheduled restore checks.

The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

Networking & Provisioning

WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
