Re: General Questions regarding Cloudstack

[Vivek Kumar]

Hello Bryan, 

For concern 1- 

There are couple of ways to achieve this.

1- You can use affinity groups ( host anti affinity ) where it will make sure 
that you applications will be powered on separate hosts.
2- You can use HOST TAG to define your hosts in compute offering. If you want 
your application to be powered on any specific host.
3- You can create 2 cluster and isolated them by using the TAG either host and 
storage tag.

But if you want to use host_tag  then I suggest to use at least 2-2 host for 
same tag, so that VMs can be powered on if any host goes down, because 
cloudstack will specifically see the tagged host so if the tagged host is not 
available then you won’t be able to power on you workload.

For Concern 2:

For this, I guess you will have to deploy some testing workload on VM and 
compare the performance with the baremetal, You can use tools like IOmeter, FIO 
for testing the random and sequential read/write and throughput. Because 
Databases required good I/O so underlying storage would be the critical 
component.

I hope this helps..!

Re: Console View Not Working

[Granwille Strauss]

Hi Guys

Any advice on this?

Hi Guys

Sorry for the many requests, this should be my last one.

I have an existing zone with 11 VMs running, the current consolevm 
works perfectly fine for 11 VMs. I also set consoleproxy.url.domain in 
global config to use a subdomain name such as console.domain.name and 
have a A record configured in DNS making it fully accessible on its 
public IP.


I now added a new zone, new IP private space to my existing cloudstack 
management. Now I have a new consolevm for this new zone, its is 
running and agent is connected. However, whenever I want to access 
console view for SSVM or ConsoleVM its just "connecting".


As per previous email thread: 
http://markmail.org/thread/azna4sh23nxgldc5 I have tested the 
following and its working perfectly fine, see attached screenshots.


I also added an additional A record to the subdomain name to include 
the new consolevm public IP with the hopes it would work. But nothing 
yet. Do anyone know what else I can try, please?

General Questions regarding Cloudstack

[Bryan Tiang]

Hi Guys,

Im a Business Development Manager trying to convince our company to convert our 
datacenter into a Private Cloud using Cloudstack. Currently things are set up 
in a Baremetal sort of set up. Im not super technical, more so on a business 
and risk side of things. And to have this approved by our management, I will 
need to address some of their concerns.

Concern 1:
Some of our applications requires High Availability. On a software level, we 
have covered this. But on a hardware level, is there a way to deploy our 
applications in a way where each HA Service is deployed in a different physical 
server (or cluster). This is to avoid any one server taking down the entire 
service (assuming both HA Applications are deployed as separate VMs, but in the 
same physical server).

Concern 2:
Is there any benchmarks only that compares the performance of bare metal and 
VM? I understand there is a slight drop in performance, but how much is that? 
Some of the system we currently deploy on bare metal are MSSQL Databases and 
other services that have very high network IO. Are any benchmarks available 
online? And can those performance degredations be restored/matched by 
compensating with more CPU/RAM allocation to the VM?

Appreciate the help.

Regardfs,
Bryan
