One of two NSFCloud mid-scale experimental computing research infrastructures, Chameleon is a deeply reconfigurable cloud computing testbed supporting large-scale Computer Science experimentation. Located at the University of Chicago and the Texas Advanced Computing Center, it is composed of over 600 compute nodes and a total of 5 petabytes of storage supporting data-intensive science. Since its public availability in July 2015, Chameleon has attracted a community of over 1,300 users working on over 200 education and research projects.In Phase 2 of the NSFCloud program, this project will expand Chameleon capabilities and capacity, and will fulfill its mission of serving as a testbed that is used extensively by the research community by:1) broadening the set of supported experiments through the addition of new hardware and software supporting high bandwidth and Software Defined Networking (SDN)2) providing operational sustainability by streamlining operations, packaging the testbed as open source software that can be leveraged by others, and developing a process for adding resources to the testbed3) provide support for managing, understanding, comparing and reproducing Computer Science experiments, and4) focusing effort on building an engaged community around the testbed via both traditional outreach including targeted training and education efforts, and direct personalized outreach to experimenters.

变色龙是NSFCloud的两个中型实验计算研究基础设施之一，是一个深度可重构的云计算测试平台，支持大规模计算机科学实验。它位于芝加哥大学和德克萨斯高级计算中心，由600多个计算节点和总计5pb的存储组成，支持数据密集型科学。自2015年7月公开发布以来，变色龙已经吸引了超过1300名用户参与200多个教育和研究项目。在NSFCloud计划的第二阶段，该项目将扩展变色龙的能力和容量，并将通过以下方式完成其作为研究界广泛使用的测试平台的使命：1)通过增加支持高带宽和软件定义网络（SDN）的新硬件和软件来扩大支持的实验集；2)通过简化操作提供操作可持续性；将测试平台打包为开源软件，可以被其他人利用，并开发一个过程来向测试平台添加资源；3)为管理、理解、比较和再现计算机科学实验提供支持；4)通过传统的扩展（包括有针对性的培训和教育工作）和直接个性化的扩展（对实验人员），集中精力围绕测试平台建立一个参与社区。
