Hi All,
My need is to make a service like AWS based on Eucalyptus. According to the network topology mentioned at http://72.47.234.81/wiki/EucalyptusNetworkConfiguration_v2.0, I have some thoughts.
In figure 1, all machines have one ethernet device, and connected to public network. By using STATIC mode, this works best to me, avoiding heavy load on gateway machine as in the figure 2. The problem to me is that Eucalyptus does not support adding IP to IP pool dynamically. According to the document, to add IP to IP pool, I must terminate all instances, then modify config file, then do clean restart. This procedure can't apply to business. For example, I have many customers using my Eucalyptus cloud. I can't terminate their servers (instances) if my IP pool is not enough any more. I dont know how much customers I will have, so I can't buy many public IP for my cloud. Maybe tens of IPs, some time later, the number of customers increases, it forces to add more IPs to the pool.
I really want to use Eucalyptus providing many services. Please give me advice.
Thanks,
Cuong.
- with a running instance, how could I change the VM type without losing existing data inside instances? For example, my customer at first chooses c1.small VM type, sometime later he wants to choose c1.medium for his need.
- If my running instance has a problem, need to shutdown to troubleshoot it, how could I do that? Because life cycle of eucalyptus instances maybe lack of shutdown state. Eucalyptus just has terminate capability, it will remove completely that instance when terminating instances.
- Maybe there is an issue with SC overload. For example, within a cluster I have 100 instances using AoE from SC. This will make heavy load on SC. How could I solve this issue?
Look forward to your replies. Thank you very much.
Cuong.
