evolve at different rates, or adopt architecture features, driven by local choices or available resources, especially with space deployments. The possibility of deployments of something that might be described as a “private cloud” being deployed in a space
habitat context was proposed, or of various distributed servers. This all warrants much more discussion.</span><span lang="EN-GB"><o:p></o:p></span></li></ol>
