Tailored SwiftStack update should help get your GDPRse in gear

But code and admin roles more complicated as a result


Object storage life is getting more complicated as public cloud dispersion meets GPDR data locality restrictions. Combining the two adds product and administration complexity.

Against this background SwiftStack has updated its open-source, object storage product with features for public cloud archiving, synchronization, and multi-region data management.

V5.0 SwiftStack was introduced in March this year, with Cloud Sync, a replication facility for on-premises to/from public cloud data movement.

We now have v5.9, the second significant product update this year, which boasts new options for multi-region data durability and policies in its single namespace while providing GPDR-driven options on data locality.

The Cloud Sync tool has policy-driven features for public cloud archiving and on-premises data rehydration, in which archived data is automatically rehydrated to on-premises infrastructure when requested.

There's a quasi form of stubbing. SwiftStack auto-tiers cold data to public clouds, with the data still accessible in a single namespace and, via an icon (quasi-stub) in the namespace listing, flagged as being at rest remotely. When the data is accessed then it is brought back on-premises.

V5.9 now offers multi-region erasure coding. SwiftStack says that, rather than spreading parity bits across all available regions, it "uses the nodes in each region and keeps the data whole in each global location. This makes data more likely to remain available even if an entire server node goes offline, and reduces the need to transfer large amounts of data from another region in the event of a request or rebuild."

Public cloud data placement can now be controlled more precisely, as admin staff "can specify how many replicas of the data should be kept in each region, and which nodes within regions to store the data based on a tiering strategy that combines high-capacity nodes and low-latency nodes with solid state drives.

"If a region goes down or an application has to be moved, data is automatically accessed on nodes in another region without requiring any changes."

SwiftStack says legacy applications can access and consume the same data from the single namespace via file services, with cloud-native applications doing it via object APIs.

Against a background of legacy apps co-existing with, and transitioning to, cloud-native ones, granular GPDR data placement controls meet the desirability of multi-region, multi-cloud archiving. SwiftStack life gets more complex as a result. ®

  • How ICE became a $2.8b domestic surveillance agency
    Your US tax dollars at work

    The US Immigration and Customs Enforcement (ICE) agency has spent about $2.8 billion over the past 14 years on a massive surveillance "dragnet" that uses big data and facial-recognition technology to secretly spy on most Americans, according to a report from Georgetown Law's Center on Privacy and Technology.

    The research took two years and included "hundreds" of Freedom of Information Act requests, along with reviews of ICE's contracting and procurement records. It details how ICE surveillance spending jumped from about $71 million annually in 2008 to about $388 million per year as of 2021. The network it has purchased with this $2.8 billion means that "ICE now operates as a domestic surveillance agency" and its methods cross "legal and ethical lines," the report concludes.

    ICE did not respond to The Register's request for comment.

  • Fully automated AI networks less than 5 years away, reckons Juniper CEO
    You robot kids, get off my LAN

    AI will completely automate the network within five years, Juniper CEO Rami Rahim boasted during the company’s Global Summit this week.

    “I truly believe that just as there is this need today for a self-driving automobile, the future is around a self-driving network where humans literally have to do nothing,” he said. “It's probably weird for people to hear the CEO of a networking company say that… but that's exactly what we should be wishing for.”

    Rahim believes AI-driven automation is the latest phase in computer networking’s evolution, which began with the rise of TCP/IP and the internet, was accelerated by faster and more efficient silicon, and then made manageable by advances in software.

  • Pictured: Sagittarius A*, the supermassive black hole at the center of the Milky Way
    We speak to scientists involved in historic first snap – and no, this isn't the M87*

    Astronomers have captured a clear image of the gigantic supermassive black hole at the center of our galaxy for the first time.

    Sagittarius A*, or Sgr A* for short, is 27,000 light-years from Earth. Scientists knew for a while there was a mysterious object in the constellation of Sagittarius emitting strong radio waves, though it wasn't really discovered until the 1970s. Although astronomers managed to characterize some of the object's properties, experts weren't quite sure what exactly they were looking at.

    Years later, in 2020, the Nobel Prize in physics was awarded to a pair of scientists, who mathematically proved the object must be a supermassive black hole. Now, their work has been experimentally verified in the form of the first-ever snap of Sgr A*, captured by more than 300 researchers working across 80 institutions in the Event Horizon Telescope Collaboration.

    We take a look at low, low subscription prices – not that we want to give anyone any ideas

    A Tor-hidden website dubbed the Eternity Project is offering a toolkit of malware, including ransomware, worms, and – coming soon – distributed denial-of-service programs, at low prices.

    According to researchers at cyber-intelligence outfit Cyble, the Eternity site's operators also have a channel on Telegram, where they provide videos detailing features and functions of the Windows malware. Once bought, it's up to the buyer how victims' computers are infected; we'll leave that to your imagination.

    The Telegram channel has about 500 subscribers, Team Cyble documented this week. Once someone decides to purchase of one or more of Eternity's malware components, they have the option to customize the final binary executable for whatever crimes they want to commit.

  • Ukrainian crook jailed in US for selling thousands of stolen login credentials
    Touting info on 6,700 compromised systems will get you four years behind bars

    A Ukrainian man has been sentenced to four years in a US federal prison for selling on a dark-web marketplace stolen login credentials for more than 6,700 compromised servers.

    Glib Oleksandr Ivanov-Tolpintsev, 28, was arrested by Polish authorities in Korczowa, Poland, on October 3, 2020, and extradited to America. He pleaded guilty on February 22, and was sentenced on Thursday in a Florida federal district court. The court also ordered Ivanov-Tolpintsev, of Chernivtsi, Ukraine, to forfeit his ill-gotten gains of $82,648 from the credential theft scheme.

    The prosecution's documents [PDF] detail an unnamed, dark-web marketplace on which usernames and passwords along with personal data, including more than 330,000 dates of birth and social security numbers belonging to US residents, were bought and sold illegally.
