open source軟件：CloudSlang介紹

1. 介紹

1. 介紹

CloudSlang是一個基於工作流的軟件的編排軟件，寫相應的yaml格式的DSL來定義工作流。

有三部分組成：the CloudSlang Orchestration Engine, the CloudSlang language and the ready-made CloudSlang content.

2. 特點

CloudSlang and its orchestration engine are:

• Process Based: allowing you to define the ‘how’ and not just the ‘what’ to better control the runtime behavior of your workflows.
• Agentless: there are no agents to set up and manage on all your machines. Instead, workflows use remote APIs to run tasks.
• Scalable: execution logic and distribution are optimized for high throughput and are horizontally scalable.
• Embeddable: the CloudSlang Orchestration Engine is distributed as a standard java library, allowing you to embed it and run CloudSlang from your own applications.

• Content Rich: you can build your own flows, or just use CloudSlang ready-made content.

3. 快速開始

Download, Unzip and Run

• Download the CLI with content zip file.
• Unzip the archive.
• Run the CloudSlang executable in the cslang-cli/bin folder.
• At the prompt enter:

run --f ../content/io/cloudslang/base/print/print_text.sl --i text=Hi

• The CLI will run the ready-made print_text operation that will print the value passed to the variable text to the screen

4. 已有的支持模塊
