Keeping an eye on CloudStack

Zenoss backs Citrix’s CloudStack by extending ZenPack with monitoring solution

Chris Mayer

The cloud infrastructure battle is well underway and now IT-ops focused Zenoss puts its chips down on the Apache Foundation’s IaaS.

A month on from the groundbreaking announcement that Citrix were
abandoning the open source OpenStack, in favour submitting their
own offering, Citrix CloudStack to the Apache Foundation, we’ve
seen numerous companies come out in support of each IaaS.

The Citrix decision wasn’t entirely surprising, considering
their wishes to emulate the successes of Apache projects Cassandra
and Hadoop, but also to maintain API compatibility with Amazon Web
Services EC2. By moving to the Apache Foundation, Citrix will
certainly broaden usage and give the company the community they
desire. Not that it’s bad already, bringing an estimated 30,000
commmunity members across with the move.

It’s fair to say that OpenStack has talked the loudest so far,
with some reputable partners pledging to OpenStack, such as Red
Hat, the still in-beta Rackspace and HP, but Citrix has been
plotting to make sure it gets it right first, before making loud

Yesterday, IT-operations software leader Zenoss firmly committed
to CloudStack, by announcing extension to their open source
CloudStack ZenPack – promising to extend montoring capabilities to
VMs using CloudStack

This move, announced at Citrix Synergy should theoretically give
enterprises greater vision into the CloudStack infrastructure,
especially helpful for newer converts looking to learn the ropes.
The new and improved CloudStack ZenPack now monitors the underlying
core VMs key to the system’s operation. This includes router
VMs, secondary storage VMs and console proxy VMs, to ensure service
performance on CloudStack.

Newcomers are often unsure of how these VMs interlink and how
this affects performance. This solution should offer an unified
view, rather than providing logistics of individual technical

Now CloudStack users have a deeper understanding of the
performance of these systems and how they correlate to other
devices within the infrastructure with a unified view of the
service rather than individual technical components.

“Last month, CloudStack became the first cloud platform in the
industry to be submitted to the Apache Software Foundation, with a
mission of delivering a powerful, proven, hypervisor-agnostic
platform that helps customers of all sizes build robust clouds,”
said Chet Luther, Principal Engineer and Architect of the
CloudStack ZenPack. “Zenoss aims to support this mission by working
with our commercial and open source customers to continue enhancing
our CloudStack ZenPack and providing a powerful unified monitoring
solution for CloudStack deployments.”

We talked to Technical Evangelist at Zenoss, Floyd Strimling
about this initiative, who was understandably excited at the
potential for ZenPack, but first we talked about the entire
landscape change:

Zenoss has always really been looking at the latest and greatest
of the orchestration vendors, so we’ve worked with OpenStack since
close to the beginning, and done a lot of work with CloudStack.
Within the CloudStack realm as you know, there’s been exciting
movement with Citrix going all-in the open source world with ASF,
but also commercially with Citrix CloudPortal.

Subsequently we’ve been encountering that quite a lot of our
customers are using CloudStack, asking for more and more
functionality…We’ve worked in conjunction with the open source
community and some of our vendors (names undisclosed). The key was
go deeper into the CloudStack, to be able to discover the top-end
information, but to go very much deeper into router VMs, storage
VMs and console VMs to be able to see the system as a whole.

We’re very big on understanding that the way to solve these
problems is to visually understand the interactions and
dependencies between the underlying infrastructure and the
software. We do that by using a real-time service model which is an
object-oriented database. From that we can maintain all those
moving dependencies so we added the correlation of CloudStack hosts
and VM components to the underlying devices and that allows us to
visually abstract across the entire infrastructure.

It’s a good gesture from Zenoss on many fronts – to
understanding what the open source community (especially newer
enterprises) want from CloudStack but also to become part of their
wider ecosystem.
