Mesosphere's 'data center OS' now free for world+dog (almost)

Community Edition hits general availability, but so far it's for Amazon's cloud only


VC-backed Mesosphere says its Datacenter Operating System (DCOS) is now generally available in a free Community Edition.

Mesosphere DCOS is a platform for running and managing clustered data center workloads that combines Apache Mesos with a mix of open source and proprietary components.

Essentially, it's cloud infrastructure in a box – although the actual resources that make up the cloud could be in a local data center, on a public cloud, or in a hybrid configuration.

A number of prominent companies, including Apple and Twitter, are already running large Mesos clusters. Mesosphere says it aims to let other companies do the same, even if they don't have the IT and engineering budgets of the big players.

"Mesosphere wants bring the benefits of Mesos, and then some, to companies of all shapes and sizes," Mesosphere senior research analyst Derrick Harris said in a blog post announcing the release. "We want to let users build and deploy applications whose components span entire datacenters, but with the simplicity of programming for a single machine."

To that end, Mesosphere has taken the core Apache Mesos software, combined it with other components including Chronos and Marathon, piled on custom web and command line UIs, and made it easier to package and install services to run on the platform.

DCOS also supports other popular cloudy tech, including Docker containers and the Kubernetes orchestration software that's beloved by the likes of Google and CoreOS. But while DCOS includes and integrates with a variety of open source technologies, Mesosphere pointedly notes that the combined offering is not itself open source.

DCOS will be available in two versions, including the aforementioned Community Edition that's available at no charge and an Enterprise Edition that isn't.

Additional benefits of the Enterprise Edition include 24×7×365 support, training, installation and configuration help, emergency patches, and support for bare metal, virtualized, and hybrid deployments – although you'll need to contact Mesosphere about a subscription to find out just what all this might cost you.

The catch with the Community Edition, on the other hand, is that you can't download it and use it with your local infrastructure – at least not so far. The idea is that you'll try out DCOS on a public cloud. You can deploy it to Amazon Web Services (AWS) beginning on Tuesday, and support for Microsoft Azure and Google Compute Engine is in beta.

Mesosphere was founded in 2013 and the startup has so far raised approximately $50m in venture capital funding. Among its employees it counts Benjamin Hindman, who began work on Mesos in 2009 while a PhD student at the University of California, Berkeley. Hindman later brought the tech to Twitter – which makes extensive use of it – before joining Mesosphere in 2014. ®

  • Mega's unbreakable encryption proves to be anything but
    Boffins devise five attacks to expose private files

    Mega, the New Zealand-based file-sharing biz co-founded a decade ago by Kim Dotcom, promotes its "privacy by design" and user-controlled encryption keys to claim that data stored on Mega's servers can only be accessed by customers, even if its main system is taken over by law enforcement or others.

    The design of the service, however, falls short of that promise thanks to poorly implemented encryption. Cryptography experts at ETH Zurich in Switzerland on Tuesday published a paper describing five possible attacks that can compromise the confidentiality of users' files.

    The paper [PDF], titled "Mega: Malleable Encryption Goes Awry," by ETH cryptography researchers Matilda Backendal and Miro Haller, and computer science professor Kenneth Paterson, identifies "significant shortcomings in Mega’s cryptographic architecture" that allow Mega, or those able to mount a TLS MITM attack on Mega's client software, to access user files.

  • HashiCorp tool sniffs out configuration drift
    OK, which of those engineers tweaked the settings? When infrastructure shifts away from state defined by original code

    HashiConf HashiCorp has kicked off its Amsterdam conference with a raft of product announcements, including a worthwhile look into infrastructure drift and a private beta for HCP Waypoint.

    The first, currently in public beta, is called Drift Detection for Terraform Cloud, and is designed to keep an eye on the state of an organization's infrastructure and notify when changes occur.

    Drift Detection is a useful thing, although an organization would be forgiven for thinking that buying into the infrastructure-as-code world of Terraform should mean everything should remain in the state it was when defined.

  • End of the road for biz living off free G Suite legacy edition
    Firms accustomed to freebies miffed that web giant's largess doesn't last

    After offering free G Suite apps for more than a decade, Google next week plans to discontinue its legacy service – which hasn't been offered to new customers since 2012 – and force business users to transition to a paid subscription for the service's successor, Google Workspace.

    "For businesses, the G Suite legacy free edition will no longer be available after June 27, 2022," Google explains in its support document. "Your account will be automatically transitioned to a paid Google Workspace subscription where we continue to deliver new capabilities to help businesses transform the way they work."

    Small business owners who have relied on the G Suite legacy free edition aren't thrilled that they will have to pay for Workspace or migrate to a rival like Microsoft, which happens to be actively encouraging defectors. As noted by The New York Times on Monday, the approaching deadline has elicited complaints from small firms that bet on Google's cloud productivity apps in the 2006-2012 period and have enjoyed the lack of billing since then.
