Kemp load balancers
Hi
Can I use Kemp LM2600 for load balancing VMs in cloudstack.
I was looking to install Openstack but struggling so want to try cloudstack
but have these LBs as I require SSL offloading.
Regards
Ian

Hi Ilya,
This should not be that hard to script either. If you use one of the APIs (like CloudMonkey) to launch your VMs you can query to see what IP was assigned to the machine(s) and then communicate that to your LB using whatever API kemp has.

Since the vendor or the ACS community has not integrated ACS with Kemps, you
can workaround the situation as below:
1) Spin up your VMs
2) Note down the IPs of the VMs
3) Run the Kemps in the same network or atleast ensure that the Kemp can
route traffic to the VM subnet
4) Configure your VIP on the Kemp and add the VMs are reals
5) Modify VM’s ACLs to allow inbound traffic from the VIP
With the Kemp integration into cloudstack, all of this should be doable
from the ACS UI itself but that will have to wait.

Looks straightforward enough to get started on ACS.

Hi Ilya
I might of not been specific enough in my original email, I want to use the
Kemps as load balancers/ssl termination for the VMs and not for the
Cloudstack system. Yes, it would be great to have them integrated into
Cloudstack like the Netscallers and F5 but I don't have the time and
resource to consider using my java development team to write a plugin at
this stage.
My plan based on my Openstack scenario, is the Kemps which are clustered
have VIPs set tot he front end web servers which are running on VMs inside
the cloud.
My setup is 2 management servers which would be running mariadb cluster and
two KVM hosts and a Dell EQLX SAN for running the VMs [to replicate the
'running VMs from SAN - block storage' in Openstack.
Is this workable and is there any potential issues with this setup?

Ian

Welcome to CloudStack user mailing list,
To be honest, I've not heard of Kemp, but did research just now and it
sounds interesting.
As it stands, there isn't anything that i'm aware of that will work with
Kemp and CloudStack natively. We have typical LB vendors like Citrix
NetScaler, BigIP F5, Brocades and plenty of other providers, but nothing
that would do load balancing with Kemp yet. There were talks of using
nginx as LB as well, not certain how far it got.
Perhaps you can try dev mailing list to see if anyone has any experience
or plans on supporting it. Alternatively, you can place a feature
request, but if demand is low, it will have the least priority. What
generally happens as well - is vendor writting support for CloudStack
and donating it to Apache Software Foundation. This is usually driven by
demand from the customers.
What many other companies do, is use their own dashboard with cloudstack
engine behind the scenes, this way they can also tie in custom solutions
including something like Kemp LB or any other technology.
Last but not least you can contract someone to write a support for it,
you can choose to donate it or not - but it would mean you have to
continuously maintain the code base on your own, if you were to upgrade
to the next version.
Regards
ilya
PS: most of the folks who are now using CloudStack initially tried
OpenStack and for obvious reasons you've mentioned - made the right choice.
