SUSE manager boosts efficiency

Published

on

SUSE Manager 3 is now available to help customers reduce the complexities of managing their IT infrastructures, a key advantage as they look to cut costs and increase the responsiveness required to adopt DevOps and hybrid cloud solutions.

With 77 percent of enterprises adopting private clouds to increase agility and innovation, the corresponding rise in IT complexity requires the enhanced management, automation and monitoring of SUSE Manager.

SUSE Manager 3 is the latest Linux server management solution that provides comprehensive lifecycle management and monitoring for Linux servers across distributions, hardware architectures, virtual platforms and cloud environments. SUSE Manager 3 includes Salt automation software and features improved configuration management, easier subscription management and enhanced monitoring capabilities.

“SUSE Manager is built to improve IT responsiveness to changing business demands, enhancing configuration automation with the integration of Salt,” said Ralf Flaxa, president of engineering for SUSE. “SUSE Manager 3 is even more valuable to large and very complex data center environments where ease of management, scalability, performance and high availability are extremely important. Customers know manually updating, patching and configuring servers can be difficult and time consuming, but SUSE Manager solves that problem while reducing costs with automated, centralised management of their Linux systems.”

Mary Johnston Turner, research vice president for enterprise system management software at IDC, said, “SUSE Manager 3 represents an important extension of functionality that directly addresses the needs of today’s DevOps and hybrid cloud management teams. SUSE Manager’s new integration with Salt delivers customers a single integrated tool that moves beyond traditional Linux server provisioning and power management to enable much more automated and scalable configuration, provisioning, patch management, monitoring and reporting for mixed Linux platforms deployed in physical, virtual or cloud infrastructures.”

SUSE Manager 3 is the best open source IT management solution to manage multiple Linux distributions, hardware platforms including x86, IBM Power Systems and z Systems, as well as physical, virtual and cloud environments – all from a centralised console. Key new benefits include:

·         Increased IT efficiency with improved configuration management via Salt. Using Salt-based configuration management, customers can deploy tens of thousands of systems without compromising speed or security. With real-time configuration and monitoring, the time to patch hundreds or even thousands of servers in large environments is significantly reduced.

·         Optimised use and management of SUSE subscriptions. The new subscription management tool in SUSE Manager provides detailed insights into usage of SUSE products, identifying the over or under utilisation of subscriptions. This helps ensure customers pay only for subscriptions they need, when they need them.

·         Reduced IT complexity with enhanced monitoring capabilities using the Nagios-compatible Icinga monitoring server. Monitoring integration with Icinga enables additional reporting capabilities and provides easy-to-use monitoring solutions and flexibility to add-on management functions. Customers also have the flexibility to use existing in-house monitoring solutions with SUSE Manager, improving control and management of IT assets.

“SUSE’s use of Salt in SUSE Manager 3 enhances not only configuration management but also predictive orchestration needed for modern enterprise Linux environments,” said Mark Chenn, CEO of SaltStack. “With the highly scalable, flexible and real-time attributes of Salt automation software, SUSE customers will be able to more efficiently manage cloud, virtual and bare metal Linux infrastructure and application environments, resulting in reduced administrative effort, increased IT productivity and improved security and reliability.”

Money talks and electronic gaming evolves

Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.

The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.

The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games. 

It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.

MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.

“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”

New phenomena, often associated with the flavour of the moment, also emerge every year.

“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain unpacked

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.

Published

on

This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.

What is blockchain?

A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.

A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.

Each block stores:

–           A number of valid records or transactions.
–           Information referring to that block.
–           A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.

Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.

As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.

How is blockchain so secure?

Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.

Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.

In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.

What else can blockchain be used for?

Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.

Use of blockchain in healthcare

Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.

Use of blockchain for documents

Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.

Other blockchain uses

This technology could also revolutionise the Internet of Things  (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.

Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.

Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
