| <p class="second">ElasticJob 是一个分布式调度解决方案，由 2 个相互独立的子项目 ElasticJob-Lite 和 ElasticJob-Cloud 组成。</p> |
| <p class="second">ElasticJob-Lite 定位为轻量级无中心化解决方案，使用jar的形式提供分布式任务的协调服务；<br />ElasticJob-Cloud 使用 Mesos |
| 的解决方案，额外提供资源治理、应用分发以及进程隔离等服务。</p> |
| <p class="second">ElasticJob 的各个产品使用统一的作业 API，开发者仅需要一次开发，即可随意部署。</p> |
