Except every other provider enables swap by default.
I understand another reason why they don't do it though... SSD has a very low amount of writes available, and if low mem machines are swapping all the time, then the SSD will wear out much more quickly.
Another annoying thing is that they disabled resizing the SSD space used. So now, when people upgrade from say 20GB to 30GB there is no easy way to do it. They did used to do this, but they disabled the easy interface for it. So lots of people upgrading are not getting what they paid for, or expected (easy upgrades of VMs).
- camus2 13y ago> Except every other provider enables swap by default. then why dont you switch to another one? if other providers are better?
- tgeek 13y ago"Except every other provider enables swap by default." This is false and 100% incorrect. Most AMI's on AWS don't enable SWAP by default whether supplied by a 3rd party or AWS themselves. Its not a forced thing either way. In October Rackspace announced that they would be getting rid of SWAP by default: http://www.rackspace.com/knowledge_center/article/changes-to-swap-on-cloud-servers http://www.rackspace.com/knowledge_center/article/changes-to... Linux VM's in Azure don't have Swap by default: http://blogs.msdn.com/b/windowsazure/archive/2013/07/29/swap-space-in-windows-azure-virtual-machines-running-pre-built-linux-images-part-1.aspx http://blogs.msdn.com/b/windowsazure/archive/2013/07/29/swap... On any host, physical or not, with more than 2GB of RAM people haven't run SWAP for years now. On cloud providers, even hosts with less than 2GB it is rarely worth it. It has horrible performance ramifications even when backed by SSD for the local host and any other tenants on that shared host. This isn't a scam or them trying to upsell you. This is smart people who know systems operations making the right call for their customers.
- Volundr 13y agoActually Linode is the only one I know of that does. Rackspace, many EC2 images, Chunkhost, etc all leave swap disabled by default.
- falcolas 13y agoAWS micro instances do not have swap or overcommit enabled by default. Caused me problems when trying to run a Go program.
