Red Hat has announced the general availability of Red Hat Enterprise Linux 7.4 with new automation capabilities designed to limit IT complexity while enhancing security.

Red Hat Enterprise Linux 7.4 offers new automation capabilities designed to limit IT complexity while enhancing workload security and performance for traditional and cloud-native applications. This provides a powerful, flexible operating system backbone to address enterprise IT needs across physical servers, virtual machines and hybrid, public and multi-cloud footprints.

From traditional physical servers and virtual machines to next-generation cloud and container services, the operating system serves as a critical linchpin in connecting deployment footprints across the enterprise. Red Hat Enterprise Linux 7 acts as this keystone by pairing open source innovation with enterprise-grade stability, providing a foundation for digital transformation while still maintaining existing systems and workloads.

Security Features

As threats to IT infrastructure evolve, enterprises require more security innovation in their software stack to help prevent breaches and more proactively manage vulnerabilities. This innovation starts at the operating system level, and Red Hat Enterprise Linux 7.4 brings to bear new and enhanced features designed to foster a more secure production environment for mission-critical workloads, both cloud-native and traditional. This includes:

  • Updated audit capabilities to help simplify how administrators filter the events logged by the audit system, gather more information from critical events and to interpret large numbers of records.
  • USB Guard, a feature that allows for greater control over how plug-and-play devices can be used by specific users to help limit both data leaks and data injection.
  • Enhanced container security functionality with full support for using SELinux with OverlayFS helps secure the underlying file system and provides the ability to use docker and use namespaces together for fine-grained access control.

Performance

Modern business applications require more bandwidth and increased storage, placing a performance strain on traditional operating systems and hardware. Engineered to meet the needs of organizations seeking to both modernize and optimize their enterprise IT infrastructure, Red Hat Enterprise Linux 7 offers new features designed to improve the performance of both networking and storage. New features include:

  • Full support for package layering with rpm-ostree, providing a means of adding packages like monitoring agents and drivers to the host operating system.
  • The introduction of LiveFS as a Technology Preview, which enables users to install security updates and layer packages without a reboot.

Management and automation

With datacenter footprints that span from bare-metal to the cloud, the complexity associated with controlling IT environments continues to increase. Complementing the capabilities of Red Hat Satellite and automation via Ansible Tower, Red Hat Enterprise Linux 7.4 introduces Red Hat Enterprise Linux System Roles as a Technology Preview. System Roles provide a common management interface across all major versions of Red Hat Enterprise Linux, enabling an automated workflow via Ansible automation to be created once and used across large, heterogeneous Red Hat Enterprise Linux deployments without additional modifications.

Red Hat Enterprise Linux for multiple architectures

Red Hat remains committed to providing customer choice when it comes to datacenter infrastructure. Red Hat Enterprise Linux 7.4 maintains this commitment with availability across multiple architectures, including IBM Power, IBM z Systems and 64-bit ARM (as a Development Preview). For the IBM Power Little Endian architecture, this release enables support for the High Availability and Resilient Storage Add-Ons as well as the Open Container Initiative (OCI) runtime and image format.

When will we stop calling them phones?

If you don’t remember when phones were only used to talk to people, you may wonder why we still use this term for handsets, writes ARTHUR GOLDSTUCK, on the eve of the 10th birthday of the app.

Published

Do you remember when handsets were called phones because, well, we used them to phone people?

It took 120 years from the invention of the telephone to the use of phones to send text.

Between Alexander Graham Bell coining the term “telephone” in 1876 and Finland’s two main mobile operators allowing SMS messages between consumers in 1995, only science fiction writers and movie-makers imagined instant communication evolving much beyond voice. Even when BlackBerry shook the business world with email on a phone at the end of the last century, most consumers were adamant they would stick to voice.

It’s hard to imagine today that the smartphone as we know it has been with us for less than 10 years. Apple introduced the iPhone, the world’s first mass-market touchscreen phone, in June 2007, but it is arguable that it was the advent of the app store in July the following year that changed our relationship with phones forever.

That was the moment when the revolution in our hands truly began, when it became possible for a “phone” to carry any service that had previously existed on the World Wide Web.

Today, most activity carried out by most people on their mobile devices would probably follow the order of social media in first place – Facebook, Twitter, Instagram and LinkedIn all jostling for attention – and  instant messaging in close second, thanks to WhatsApp, Messenger, SnapChat and the like. Phone calls – using voice that is – probably don’t even take third place, but play fourth or fifth fiddle to mapping and navigation, driven by Google Maps and Waze, and transport, thanks to Uber, Taxify, and other support services in South Africa like MyCiti,  Admyt and Kaching.

Despite the high cost of data, free public Wi-Fi is also seeing an explosion in use of streaming video – whether Youtube, Netflix, Showmax, or GETblack – and streaming music, particularly with the arrival of Spotify to compete with Simfy Africa.

Who has time for phone calls?

The changing of the phone guard in South Africa was officially signaled last week with the announcement of Vodacom’s annual results. Voice revenue for the 2018 financial year ending 31 March had fallen by 4.6%, to make up 40.6% of Vodacom’s revenue. Total revenue had grown by 8.1%, which meant voice seriously underperformed the group, and had fallen by 4% as a share of revenue, from 2017’s 44.6%.

The reason? Data had not only outperformed the group, increasing revenue by 12.8%, but it had also risen from 39.7% to 42.8% of group revenue,

This means that data has not only outperformed voice for the first time – as had been predicted by World Wide Worx a year ago – but it has also become Vodacom’s biggest contributor to revenue.

That scenario is being played out across all mobile network operators. In the same way, instant messaging began destroying SMS revenues as far back as five years ago – to the extent that SMS barely gets a mention in annual reports.

Data overtaking voice revenues signals the demise of voice as the main service and key selling point of mobile network operators. It also points to mobile phones – let’s call them handsets – shifting their primary focus. Voice quality will remain important, but now more a subset of audio quality rather than of connectivity. Sound quality will become a major differentiator as these devices become primary platforms for movies and music.

Contact management, privacy and security will become critical features as the handset becomes the storage device for one’s entire personal life.

Integration with accessories like smartwatches and activity monitors, earphones and earbuds, virtual home assistants and virtual car assistants, will become central to the functionality of these devices. Why? Because the handsets will control everything else? Hardly.

More likely, these gadgets will become an extension of who we are, what we do and where we are. As a result, they must be context aware, and also context compatible. This means they must hand over appropriate functions to appropriate devices at the appropriate time. 

I need to communicate only using my earpiece? The handset must make it so. I have to use gesture control, and therefore some kind of sensor placed on my glasses, collar or wrist? The handset must instantly surrender its centrality.

There are numerous other scenarios and technology examples, many out of the pages of science fiction, that point to the changing role of the “phone”. The one thing that’s obvious is that it will be silly to call it a phone for much longer.
