There is no need to share any storage between the nodes. What you need is to configure ElasticSearch to use its clustering features. This is very easy, check your config file and it should be very well commented. Otherwise, do a quick google for "elasticsearch cluster", this should help you: ...
They recommended that when running in a complete virtualized platform there is no real reason to virtualize at application layer This is potentially dangerous advice. Hyper-V clustering allows high availability in the event of a hardware failure - that is all. In-guest clustering allows for OS-level high availability in the event of a BSOD, failed ...
They recommended that when running in a complete virtualized platform there is no real reason to virtualize at application layer Incompetence. SImple like that. It totally depends on your requirements. And how you do it. SQL Server level standard clustering is active /passive and that will restart the sql server instance when the other fails, which ...
I can't speak specifically about glassfish, but it's normal to built failure-resilient LB systems with a pair of LBs, only one of which is active at any one time. If the LBs are applicances, this is done in hardware - you'll have a pair, usually with some direct connection between the two, for monitoring/heartbeat and sometimes for state exchange. If the ...
Looks like you are looking more for cloud computing than cluster computing. You should check out SUSE. They have some now cloud software that claims you can build your own cloud within 7 minutes. If you want free/open source, Ubuntu 12 supposedly supports cloud very well.
If you're open to CentOS, you can cluster with ricci/lucci that comes with CentOS. (This comment got deleted for some reason for not answering the original question so I will elaborate) You are asking about clustering 100 machines, they currently run ubuntu linux. And to EASILY make a big cluster For a BIG cluster, my response is if you are able to ...
As Sandor said, this cannot be done with standard MySQL replication. It can be done if you use a third-party / external replication mechanism. A few products that I'm aware of: Continuent Tungsten Replicator SymmetricDS Both are open source and freely available. Another option would be to migrate to a MySQL cluster. Some options: MySQL Carrier ...
No. That would require A to be slave to both B and C, which is not possible. A-›B->C->A not recommended either.
A cluster IP is the virtual IP that represents your clustered service. Typically this is the IP assigned to your clustered service on your load balancer.
Actually lets make the post more clear. It is possible to run Proxmox from PXE BUT it's not documented or supported. I recommend only advanced users try. If you get it working its amazing. You can run all your vm's straight from RAM and do not need hard drives in the system at all.
