Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs

SSH forward local port to remote AWS RDS MySQL instance.

SSH forward local port to remote AWS RDS instance

The scenario:

  • We have connectivity to remote server (EC2 instance) REMOTE_EC2_HOST over SSH.
  • Connectivity to AWS RDS MySQL instance RDS.ENDPOINT.rds.amazonaws.com from remote server only (due to security group/firewall settings).
# forward requests from 127.0.0.1:6400 -> RDS.ENDPOINT.rds.amazonaws.com:3306
# add [-f] switch to background ssh process
$ ssh -vvvN \
	-L 6400:RDS.ENDPOINT.rds.amazonaws.com:3306 \

MongoDB 3.2.x Replica Sets on AWS EC2

#MongoDB 3.2.x Replica Sets on AWS EC2 A MongoDB replica set provides a mechanism to allow for a reliable database services. The basic replica set consists of three servers, a primary, a secondary and an arbitrator. The primary and secondary both hold a copy of the data. The arbitrator is normally a low spec server which just monitors the other servers and help with the failover process. In production, there can be more than three servers.

To setup mongo as a replica set on Amazon Web Services EC2 you need to first setup a security group with ssh on port 22 and mongodb on port 27017. You then need to create three servers. Select Ubuntu 14.04 LTS x64 and a micro (or bigger depending on your database size, ideally you should have enough memory to match your database size) instance for the primary and secondary and a nano instance for the arbitrator.

##Adjust the File System on each Server The operating system by default will update the last access time on a file. In a high data throughput database application
