Was ist das? Eine neue Suse Linux Enterprise? Ausgezeichnet!

Version 12 first major-number Suse release since 2009


Suse has kicked out a new version of its enterprise-grade commercial Linux distribution, Suse Linux Enterprise 12, more than five years after the last major-version release.

Not that the German firm has been resting on its laurels in the meantime. Countless patches and updates for the platform have been released for version 11 over the years, and Suse has shipped three official "service packs" for its flagship data center product, Suse Linux Enterprise Server (SLES) 11.

Suse Linux Enterprise 12, however, brings the distro up to date with a number of popular modern technologies – including improved management capabilities, containers, and yes, even systemd – to help it better compete with the likes of CentOS, Red Hat, and Ubuntu.

The core Suse Linux Enterprise 12 distro forms the base of all of Suse's enterprise product offerings, so the new release brings with it not just SLES 12, but also new versions of the company's High Availability Extension, the Virtual Machine driver pack, and Suse Linux Enterprise Desktop (SLED).

Among the major new features of the release, support for Linux Containers (LXC) is now baked into the OS, and Docker-based container deployment and management is offered as a technology preview.

The controversial systemd management daemon replaces the older, Unix System V–style init process, and network configuration management is handled via a new system called wicked.

Also out is Oracle's MySQL database, which has been replaced by MySQL creator Monty Widenius' MariaDB fork. Several other Linux distros have already done the same, including Red Hat and its variants.

These and other changes all come wrapped in a new installer that requires fewer reboots and gives users the option of receiving all available maintenance updates as part of the installation.

SLES 12 also now supports installation without a separate boot partition, enabling full system rollback capabilities using Suse's snapper tool and btrfs as the default file system.

The full Suse Linux Enterprise 12 family is available now via subscription for 64-bit Intel architecture, IBM System z mainframes, and IBM Power processors. For the latter, only Power8 and later processors are supported, including support for the native little-endian memory model. The 32-bit Intel and Itanium architectures have also been dropped since version 11.

Free 60-day evaluations of SLES 12 are available. More detailed information about the release is available here, and detailed technical release notes are available here. ®

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    We'll see you around the Block

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.
