CoreOS alternatives

CoreOS
CoreOS is a new Linux distribution that has been rearchitected to provide features needed to run modern infrastructure stacks. The strategies and architectures that influence CoreOS allow companies like Google, Facebook and Twitter to run their services at scale with high resilience.
CoreOS alternatives are:
Docker, OpenStack, Kubernetes
Here are the latest news about CoreOS:

09.05.16 Container-centric Linux distribution CoreOS raised $28M


CoreOS, the company behind the container-centric CoreOS Linux distribution and Tectonic container management service announced that it has raised a $28 million Series B round. The company plans to use the new funding to grow its team in the U.S. and Europe. This means CoreOS will build out its sales and marketing teams, for example, so it can more effectively engage with potential customers for its paid products. The core of CoreOS’s product range is the CoreOS distribution, but the Kubernetes-based Tectonic container management platform is what brings all of these efforts together.



2015 CoreOS launched an open-source tool for monitoring container security


CoreOS, the popular lightweight Linux distribution for data center deployments with the same name, is launching Clair, an open-source tool for monitoring the security of containers. Containers make life easier for many developers, but just like a Linux distribution needs to be regularly updated to mitigate vulnerabilities, containers may also come with outdated software packages installed in them. CoreOS says over 80 percent of Docker images stored in its Quay container registry service are still vulnerable to the infamous Heartbleed bug, for example. Clair can scan containers for known vulnerabilities and then alert developers of potential issues. CoreOS is getting this data from the vulnerability databases of Red Hat, Ubuntu and Debian.



2015 CoreOS launches Tectonic to bring Kubernetes to the Enterprise


CoreOS, a Docker-centric Linux distribution for large-scale server deployments, announced that it has raised a $12 million funding round led by Google Ventures. In addition, CoreOS is also launching Tectonic - the new commercial distribution combines CoreOS with Google’s open source Kubernetes container management and orchestration tools. This makes CoreOS the first company to launch a fully supported enterprise version of Kubernetes. Overall, the new distribution, which for now is only available to a select group of beta users, aims to make it easier for enterprises to move to a distributed and container-based infrastructure. Google, it’s worth noting, has supported CoreOS on its Compute Engine service for about a year now. Given Google’s recent focus on containers on its cloud platform, a collaboration with (and investment in) CoreOS makes a lot of sense for the search giant as it competes with the likes of Amazon and Microsoft to get startups and forward-looking enterprises to adopt its platform.



2014 CoreOS invented the new container technology to fight Docker


For the past several months container technology Docker was on its way to becoming the de-facto standard for container technology. Now CoreOS, the Linux operating system specialist, is unveiling is own competitive technology - Rocket, kicking off what could become a container-standardization war between the two entities. CoreOS states, that Docker’s effort to develop its enterprise-oriented lineup of features has caused the company to lose sight of its goal of making sure that its core container technology is lightweight and portable. And that now Docker is competing with container-management-and-orchestration services like Google’s Kubernetes or the new Amazon EC2 Container service. Rocket is basically a container engine, like Docker, but without all the extras Docker’s been working on to make itself more enterprise friendly. These features include tools for spinning up cloud servers, the ability to have clustered systems and even networking capabilities.
