Blueprint changed by Ben Howard: Whiteboard changed: + STATUS: Due to bug 948461, and S3 handling HTTP pipelining properly, + this has been postponed pending a resolution from Amazon or further + discussion. + + Rationale: S3 is a faster, more scalable technology that allows us to reduce costs and increase availability for EC2 users. Assumption: * Running on-EC2 mirrors is expensive and presents availability challenges. * on-EC2 mirrors have limited bandwidth and thus speeds can be affected by load * S3 has very high availability * S3 intra-region bandwidth is free * on-EC2 mirrors results in bandwidth charges when users use a mirror outside the availability zone * S3 is extremely fast. Generally speeds to S3 access are near-native * Amazon has asked for us to host our mirrors on S3 * Uploads to S3 are free ___ Example of access via S3. deb http://BUCKET/ubuntu/ oneiric main universe multiverse restricted deb http://BUCKET/ubuntu/ oneiric-updates main universe multiverse restricted deb http://BUCKET/security oneiric-security main universe multiverse restricted deb-src http://BUCKET/ubuntu/ oneiric main universe multiverse restricted deb-src http://BUCKET/ubuntu/ oneiric-updates main universe multiverse restricted deb-src http://BUCKET/security oneiric-security main universe multiverse restricted ___ Decision: Build S3 Regional mirror Work Items [utlemming]: Add APT Meta-parsing to script: DONE [utlemming]: Make script atomic: DONE - [utlemming]: Document process: TODO - [canonical-sysadmins]: Add EC2 CNAMES: TODO - [canonical-sysadmins]: Deploy solution: IN PROGRESS + [utlemming]: Document process: DONE + [utlemming]: Deploy Solution: DONE + [canonical-sysadmins]: Add EC2 CNAMES: POSTPONED - a method of pushing pristine repositories up
