Apache CloudStack October Meetup

It has been a few months since the last meetup and in the meantime, the group is fast approaching 500 members. I hope we can get as many people as we can to participate in the upcoming meetup.

The agenda is still being finalized. It would be a good opportunity for you to present CloudStack success stories, tips and tricks, tutorials and HOWTOs. Vendors are also welcome to talk about their cloud products which have CloudStack integration. Please feel free to contact me (via the meetup link) for a slot at the earliest.

A special thanks to InMobi who have kindly offered to host the October CloudStack meetup at their premises.

A Basic zones is a flat network where SecurityGroups are used for traffic isolation while Advanced Zones can use VLAN, GRE or STT based isolation. The maximum VLANs possible per zone is 4096 while the actual number depends on the L3 switching device’s capabilities. Since every guest tenant is allocated one VLAN ID, the maximum tenants supported would be 4K tenants within the same zone. If there is a requirement to support more than 4K customers within the same zone, SDN technologies like GRE and STT can be used.

CloudStack Guest Scripts

Sometime back, I made modifications to the original generic CloudStack cloud-set-guest-password and cloud-set-guest-sshkey to make them work on other Linux distros and FreeBSD.

You can find them on Github.
