<div dir="ltr">What are the advantages of storing the imagery in S3 as opposed to EBS? I'm using the throughput optimized magnetic EBS which I is a little less expensive than S3. I did some testing a couple years ago and didn't see enough performance gain to justify SSD. Have you tested S3 against any of the EBS options?<div><br></div><div>Rich</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Mar 2, 2019 at 7:58 AM Jeremy Palmer <<a href="mailto:palmerjnz@gmail.com">palmerjnz@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr">I've now found this useful Mapserver wiki page <a href="https://github.com/mapserver/mapserver/wiki/Render-images-straight-out-of-S3-with-the-vsicurl-driver" target="_blank">https://github.com/mapserver/mapserver/wiki/Render-images-straight-out-of-S3-with-the-vsicurl-driver</a>. It seems to imply that it's better to merge a collection of dataset tiles into a single big Geotiff rather than create a VRT due to the repeated HTTP calls. I'm still interested in people's experiences using imagery direct from S3 and it's performance. </div><div dir="ltr"><br></div><div dir="ltr">Note some of my largest datasets have a total size of 1.5TBs uncompressed Geotiff with about 8000 tiles @ 175mb per tile.
