Making the internet's edge easily extensible fosters
collaboration and innovation on web-based applications, but also
raises the problem of how to secure the execution platform. This
paper presents Na Kika, an edge-side computing network, that addresses
this tension between extensibility and security; it safely opens the
internet's edge to all content producers and consumers. First,
Na Kika expresses services as scripts, which are selected through
predicates on HTTP messages and composed with each other into a
pipeline of content processing steps. Second, Na Kika isolates
individual scripts from each other and, instead of enforcing
inflexible a-priori quotas, limits resource consumption based on
overall system congestion. Third, Na Kika expresses security policies
through the same predicates as regular application functionality, with
the result that policies are as easily extensible as hosted code and
that enforcement is an integral aspect of content processing.
Additionally, Na Kika leverages a structured overlay network to
support cooperative caching and incremental deployment with low
