I have about 500 web sites that I want to host in AWS. I need to survive AWS outages so am considering Gluster in cross region replicated setup. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I had looked before at Gluster but keep coming across warnings about it being ill suited to web serving due to slow reads on small files. The worst thing I could do (besides lose all customer data!) is move from owned and happy physical hardware to Gluster backed cloud, find slow loads of sites and then have to unpick the solution again.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Also I would like to use same solution for Postfix which again is lots of small files. With Postfix though there are also lots of small file writes which seems to be another problem with Gluster.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I want the scalability and redundancy of Gluster but these things are worrying. The sites are mainly low traffic but there are a few with major peaks and some with consistent high volume. Mail is probably around 1500 pop3/imap users.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Also, at beginning I mentioned using cross region replicated setup. I suspect this may have a network overhead that could have a big io impact? Assuming Gluster is suited to Apache/MX usage, perhaps Geo replication is a better option for me with the slave as hot standby?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any help would be great thanks.<o:p></o:p></p><p class=MsoNormal>Ash<o:p></o:p></p></div></body></html>
