# Supported Platforms for Deployment CertiNext is designed as a **platform-agnostic, enterprise-grade application** that can be deployed across a wide range of infrastructure environments. Its architecture emphasizes portability, scalability, and operational flexibility, allowing organizations to align deployment with their existing technology standards and hosting strategies. *** #### Core Technology Stack CertiNext is built on **Java 21**, ensuring: * Long-term support (LTS) stability * High performance and scalability * Compatibility with modern Java ecosystems * Strong security and runtime enhancements Because CertiNext is Java-based, it can be deployed on **any standards-compliant Java application server**. *** #### Containerized Deployment (Recommended) CertiNext is **typically shipped as a Docker image** and deployed on **Kubernetes-based platforms**. This deployment model enables: * Horizontal and vertical scalability * High availability and fault tolerance * Simplified upgrades and rollbacks * Cloud-native operations across public cloud, private cloud, or hybrid environments Kubernetes deployments are commonly used in both on-premises and SaaS models and integrate seamlessly with modern CI/CD pipelines. *** #### Application Server Deployment For environments that prefer traditional application server models, CertiNext can also be shipped as a **WAR file**. This allows deployment on Java application servers such as: * Apache Tomcat * JBoss / WildFly * WebLogic * WebSphere * Other Java EE / Jakarta EE compatible servers This option is suitable for organizations with established Java application hosting standards or constrained container adoption. *** #### Infrastructure and Hosting Flexibility CertiNext can be deployed across: * On-premises data centers * Private cloud environments * Public cloud infrastructure * Hybrid architectures The platform does not impose restrictions on underlying operating systems, virtualization layers, or cloud providers, as long as Java runtime requirements are met. *** #### Operational Benefits By supporting both containerized and traditional deployment models, CertiNext enables: * Alignment with enterprise IT standards * Gradual modernization from legacy app servers to Kubernetes * Simplified portability across environments * Reduced vendor and infrastructure lock-in *** #### Summary CertiNext’s deployment flexibility is a direct result of its **Java 21-based, platform-agnostic design**. Whether deployed as a Docker container on Kubernetes or as a WAR file on a Java application server, CertiNext adapts to diverse enterprise environments—ensuring consistent certificate lifecycle management capabilities without constraining infrastructure choices. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
