Carbon Offsetting Explained | Definitions And More | Earthly Blog
Introduction In the fight against climate change our first step must always be towards changing our actions. We can do this by consuming less, consuming better, and reducing our carbon footprint. However, nobody’s perfect. And to become carbon neutral or better yet, climate positive we need to acknowledge the place for carbon offsetting. A carbon offset broadly speaking is a greenhouse gas (GHG) reduction or removal, to compensate for CO2 emissions emitted elsewhere.
Amping up innovation
The global utilities sector, which has a market capitalization of US$2.1 trillion, is at the front end of a dramatic energy transition that will radically alter future market strategies, business models, and customer interactions. As we noted in our 2019 Global power strategies report on the world’s 40 largest utilities (which we call the Global Top 40, or GT40), long-held hypotheses about market direction, pace, impacts, and requirements have been overturned.
Codetree Collect Info
We recently landed a feature in Codetree that I’m pretty excited about. Codetree is a tool for collecting code from various locations and assembling it in a specific directory structure. It can be used in a standalone fashion, but is also tightly integrated with Mojo, which we use to deploy and manage Juju models. As an example, let’s say you want to get a subset of the latest OpenStack charms.
Canonical and QCT partnership extends to next-generation managed cloud
Canonical and QCT (Quanta Cloud Technology) have extended their collaboration by bundling the most innovative managed cloud services, based on Ubuntu reference architecture on QCT hardware. Canonical’s reference architecture is designed for success, distilled from the hundreds of OpenStack clouds deployed on Ubuntu OpenStack (64% of all production environments according to the latest OpenStack Foundation survey) and built to accommodate the whole range of different workloads.
Mojo: Juju Service Orchestration distilled part 3
This is the third in a series of three articles about Mojo. In the first article we introduced Mojo, and in the second article we took a closer look at specifications and manifests. Today we’re going to walk through an example service deployment so you can see Mojo in action. The only things you’ll need to be able to follow along with this example are a computer running Ubuntu Trusty or Utopic (to be able to install Mojo from our PPA), and access to a Juju environment.
Canonical Cloud Chatter: January 2015 Newsletter
This month, we had some news on Snappy, MAAS and Mojo, but also the results to our annual cloud survey are in! If that was not enough, find out more about our event plans over the next few weeks and sign up for our latest webinar! Here’s a quick recap of an exciting start to 2015. Last month, Canonical announced snappy Ubuntu Core, the new, transactional version of Ubuntu, designed for public clouds.
Mojo: Juju Service Orchestration distilled part 2
In the previous post we introduced Mojo. Today we’re going to take a closer look at how it all fits together. is the most often used command. As a refresher, here’s the diagram explaining how Mojo’s manifest can be used in different environments: Mojo looks for a manifest file that defines the steps it should execute, and takes a option, which tells it where to find the details of those steps.
Mojo: Juju Service Orchestration distilled
In Canonical’s IS Department we use Juju for service orchestration. It’s a great tool for quickly spinning up complex services, tying them together and scaling them out or in as needed. We use it for everything from the ubuntu.com website itself to click-packages, the system that underpins the Ubuntu phone. We even use it to deploy the OpenStack instances that these services run on. All in all we have more than 60 Juju environments in production.
ScalingStack: 2x performance in Launchpad’s build farm with OpenStack
Launchpad is an open source suite of tools that help people and teams to work together on software projects, and it includes a build service with over 11,000 Personal Package Archives (PPAs). We’ve recently made some major changes to the underlying infrastructure of this system by migrating it to an OpenStack instance that we call “ScalingStack”. ScalingStack can be thought of as spot instances for Canonical.
