## What it is
Tencent Kona 8 is a no-cost, production-ready distribution of OpenJDK 8 with long-term support and quarterly updates, serving as the default JDK at Tencent. It is optimized for big data, machine learning, and cloud computing workloads and adds Chinese national cryptographic algorithms (SM2, SM3, SM4) and the TLCP/SMSSL secure protocol.

## Use cases
- run Java applications on a free production-ready OpenJDK 8 build
- get long-term support JDK with quarterly security updates
- use Chinese national cryptographic algorithms SM2 SM3 SM4 in Java
- enable TLCP SMSSL secure communication in Java applications
- run big data and machine learning Java workloads at extreme scale
- standardize a JDK across a cloud platform

## When to choose
- you need a free, LTS-supported OpenJDK 8 distribution with quarterly updates
- your applications require Chinese national cryptography (SM2/SM3/SM4) or TLCP
- you run large-scale big data, ML, or cloud workloads on the JVM
- you want a vendor-supported JDK backed by Tencent Cloud

## When to avoid
- you need a newer JDK version than Java 8
- you have no need for Chinese cryptographic algorithms or Tencent-specific optimizations
- your organization standardizes on another OpenJDK distribution such as Temurin or Corretto
- you require non-Linux/macOS/Windows platforms

## Facets
- artifact type: library
- maturity: stable
- function: programming-language, cryptography, security
- domain: cloud-computing, developer-tools, security, big-data, machine-learning
- platform: windows, jvm, cross-platform
- tags: openjdk, jdk-distribution, java, lts, chinese-cryptography, sm2, sm3, sm4, tlcp, tencent, linux, macos
