Architecture of the internet archive

摘要

The Internet Archive is a live production system supporting close to a petabyte of data and delivering an average of 2.3Gb/sec of data to Internet users. We describe the architecture of this system with an emphasis on its robustness and how it is managed by a very small team of systems personnel. Notably, the current system does not employ a cache. We analyze the reasons for this decision and show that an effective cache could not be built until now. However, new solid state disk technology may offer promising new cache implementations.
