It’s all about containers. All attention is turning to new and innovative variants of this cloud development technology. From LXC and Docker to our recent introduction, LXD – all signs point to an explosion in appetite for for containers, and the many benefits they bring to developers.

Containers are revolutionizing the way the enterprise manages cloud infrastructure. They provide flexible safe-havens to allow innovation to flourish, and, in the case of LXD, the speed and density it takes to launch hundreds of machines on a single server.

In Vancouver at ODS, the focus for the Canonical team was to bring to life the power and flexibility of LXD. Is it a hypervisor? What about Docker? How does LXC fit in and does it really crush KVM on density and speed? We’ve captured James Page and Ryan Harper’s OpenStack Summit keynote above which sought to answer all these questions and more.

Development: GNOME 3.17.3 released

Hey all,

The development of the next GNOME release, 3.17, is going on and a new
snapshot, 3.17.3, is now available.  Give it a shot!  Some of us will
gather in San Francisco next week for the West Coast Summit 2015, and
a month later we will all gather for GUADEC in Gothenburg, Sweden (no
relation whatsoever with a conspiracy that doesn't even exist).

To compile GNOME 3.17.3, you can use the jhbuild[1] modulesets[2]
(which use the exact tarball versions from the official release).

Python Vulnerabilities Closed in Ubuntu OSes

Canonical published details about a couple of Python vulnerabilities that had been found and corrected in its Ubuntu 14.10, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS operating systems.

Amidst discussions about the implementation of Python 3.5 in the latest Ubuntu systems, the maintainers have been quick to update the python2.7, python3.2, and python3.4 packages in the supported Ubuntu systems.

For example, “It was discovered that the Python CGIHTTPServer incorrectly handled… (read more)

Announcing Benchmarking with Juju

juju_machine_view

Benchmarking and performance are interesting problems, especially in today’s growing cloud-based microservice scene. It used to be a question of “how does this hardware compare to that hardware,” but as computing and service-oriented architectures grow the question has evolved. How does my cloud and application stack handle this? It’s no longer enough to run PTS on your web server and call it a day.

Measuring every microservice in your stack, from backend to frontend, is a complex task. We started thinking about how you would model a system to benchmark all of these services. It’s not just a matter of measuring the performance of one service, but also its interactions with other services. Now multiply that by every config option for every service, like PostgreSQL, which has hundreds of options that can affect performance.

Juju has been modeling service orchestration since 2010. It’s done a great job of taking complex scenarios that are now booming, such as containerization, service oriented architectures and hyperscale, and condensing those ideas down into composable, reusable, pieces. Today we’re adding benchmarking. The ability not just to define the relationships between these services, but how they should be measured in relation to each other.

As an example, monitoring the effect of adjusting the cache in nginx is a solved problem. What we’re going after is what happens when you adjust any service in your stack in relation to every other service. Turn every knob programmatically and measure it at any scale, on any cloud. Where exactly will you get the best performance: your application, the cache layer, or the backend database? Which configuration of that database stack is most performant? Which microservice benefits from faster disk I/O? These are the kinds of questions we want answered.

With Juju Actions, we can now encapsulate tasks to run against a single unit or service in a repeatable, reliable, and composable way. Benchmarking is a natural extension of Actions, allowing authors to encapsulate the best practices for measuring the performance of a service and serve those results — in a standard way — that any user or tool can digest.

We’re announcing charm-benchmark, a library written in Python that includes bash scripts so you can write benchmarks in any language. It uses action-set under the covers to create a simple schema that anyone can use and parse.

While we may intimately know a few services, we’re by no means the experts. We’ve created benchmarks for some of popular services in the charm store, such as mongodb, cassandra, mysql and siege, in order to provide a basic set of examples. Now we’re looking for community experts who are interested in benchmarking in order to fill the gap of knowledge. We’re excited about performance and how Juju can be used to model performance validation. We need more expertise on how to stress a service or workload to measure that performance.

For example, here’s what a benchmark for siege would look like:

actions.yaml:

siege: description: Standard siege benchmark. params: concurrent: description: The number of simultaneous users to stress the web server with. type: integer default: 25 time: description: The time to run the siege test for. type: string default: "1M" delay: description: | Delay each simulated user for a random number of seconds between one and DELAY seconds. type: integer default: 3

actions/siege:

#!/bin/bash set -eux # Make sure charm-benchmark is installed if ! hash benchmark-start 2&>/dev/null; then apt-get install -y python-pip pip install -U charm-benchmark fi runtime=`action-get time` concurrency=`action-get concurrency` delay=`action-get delay` run=`date +%s` mkdir -p /opt/siege/results/$run benchmark-start # Run your benchmark siege -R $CHARM_DIR/.siegerc -t ${runtime:-1M} -c ${concurrency:-25} -d ${delay:-3} -q --log=/opt/siege/results/$run/siege.log # Grep/awk/parse the results benchmark-data transactions $transactions hits desc benchmark-data transaction_rate $hits “hits/sec” desc benchmark-data transferred $transferred MB desc benchmark-data response_time $response ms asc # Set the composite, which is the single most important score benchmark-composite transaction_rate $hits hits/sec desc benchmark-finish || true

We’ll be covering benchmarking in the next Juju Office Hours on July 9th at 1600 EDT/20:00 UTC and we’d love to help anyone who wants to get started, you can find me, Adam Israel (aisrael), Marco Ceppi (marcoceppi), and Tim Van Steenburgh (tvansteenburgh) on #juju on Freenode and on the Juju mailing list.

So you want to buy a Meizu MX4 huh?

Well, you need to show you’re up for the challenge of owning an Ubuntu phone.

From tomorrow you’ll be able to buy the Meizu MX4, but only if you earn an invite. When you first visit the site you’ll see some hotspots on the origami themed wall.

meizu-01

If you’re lucky enough to find a hotspot with an invite then you’ll be able to cash in that invite and buy a brand spanking new MX4.

meizu-02

The invites are randomly generated, and if you’re not lucky enough to find one then you can try again over several days.

The idea behind it is to limit the amount of buyers, but without doing flash sales (thank God!) and making sure that people realise that it’s an Ubuntu phone they’re buying, and not an Android device.

It’s a novel idea, but I just hope there’s enough invites and units to supply the demand.

Ubuntu Fan Images

White Fan

This week, Dustin Kirkland announced the Ubuntu Fan Project.

To steal from the description, “The Fan is not a software-defined network, and relies on neither distributed databases nor consensus protocols.  Rather, routes are calculated deterministically and traffic carries no additional overhead beyond routine IP tunneling.  Canonical engineers have already demonstrated The Fan operating at 5Gpbs between two Docker containers on separate hosts.”

My team at Canonical is responsible for the production of these images. Once the official SRU’s land, I anticipate that we will publish an official stream over at cloud-images.ubuntu.com. But until then, check back here for images and updates. As always, if you have feedback, please hop into #server on FreeNode or send email.
