Inside look at Hewlett Packard’s next-generation infrastructure

In the 18 months since the company split from its sister consumer business, Hewlett Packard Enterprise has been in an almost constant state of refining its strategy.The company backed out of the public cloud market; sold off its Enterprise Services Business to competitor CSC for $8.5 billion; dealt other “non-core” assets to Micro Focus in an $8.8 billion deal; and dumped its OpenStack and Cloud Foundry development efforts off to Suse. HPE also bought all-flash storage vendor Nimble storage for $1 billion last year and snapped up hyperconverged infrastructure vendor Simplivity for another $650 million in January.To read this article in full or to leave a comment, please click here

Data centers decline as users turn to rented servers

Data centers are declining worldwide both in numbers and square footage, according to IDC -- a remarkable change for an industry that has seen booming growth for many years.Users are consolidating data centers and increasingly renting server power. These two trends are having a major impact on data center space.[ Further reading: The march toward exascale computers ] The number of data centers worldwide peaked at 8.55 million in 2015, according to IDC. That figure began declining last year, and is expected to drop to an expected 8.4 million this year.

Risk or Reward: First Nvidia DGX-1 Boxes Hit the Cloud

If you can’t beat the largest cloud players at economies of scale, the only option is to try to outrun them in performance, capabilities, or price.

While go head to head with Amazon, Google, Microsoft, or IBM on cloud infrastructure prices is a challenge, one way to gain an edge is by being the first to deliver bleeding-edge hardware to those users with emerging, high-value workloads. The trick is to be at the front of the wave, often with some of the most expensive iron, which is risky with AWS and others nipping at heels and quick to follow. It …

IDG Contributor Network: DevOps—The path to sustainable competitive advantages

A fundamental shift is happening in software development, and the way applications are built and brought to market is changing rapidly. As IT infrastructure has moved to the cloud and the age of the customer has made digital experiences pivotal in creating competitive advantages, DevOps has emerged. IT has refocused from managing servers to supporting lines of business managers and developers in their quest to provide integrated experiences across devices and touchpoints.+ Also on Network World: How DevOps can redefine your IT strategy + This shift can be compared to Henry Ford's innovation of the assembly line. Ford was able to set up a process that could produce more reliable cars faster and at lower costs. Similarly, the future of digital experiences belongs to the companies that can standardize and optimize their app delivery process. Companies that are able to align DevOps stratigeis and tools to deliver digital experiences faster and better than their competition have an advantage that will be difficult to replicate.To read this article in full or to leave a comment, please click here

IDG Contributor Network: When phone systems attack

A telephony denial of service (TDoS) attack is a specific type of DDoS attack that originates from or is directed towards a telephone system with the intent of bringing down the targeted system. These attacks commonly focus on commercial businesses and may often include ransomware requests. In reality, these attacks can affect anyone, including our nation’s 911 infrastructure, because even it is not isolated from or immune from these types of attacks. And based on its mission, in many ways, it is more fragile.Unintentional TDoS attack Just last year, 911 centers across the country, including a site in Phoenix, Arizona, were the targets of allegedly unintentional 911 TDoS attacks when some malicious JavaScript code was published on a web page. The code, once loaded on a smartphone browser, would cause some devices to automatically dial 911 repeatedly without user intervention and without the user’s knowledge. To read this article in full or to leave a comment, please click here

How we made our DNS stack 3x faster

Cloudflare is now well into its 6th year and providing authoritative DNS has been a core part of infrastructure from the start. We’ve since grown to be the largest and one of the fastest managed DNS services on the Internet, hosting DNS for nearly 100,000 of the Alexa top 1M sites and over 6 million other web properties – or DNS zones.

Today Cloudflare’s DNS service answers around 1 million queries per second – not including attack traffic – via a global anycast network. Naturally as a growing startup, the technology we used to handle tens or hundreds of thousands of zones a few years ago became outdated over time, and couldn't keep up with the millions we have today. Last year we decided to replace two core elements of our DNS infrastructure: the part of our DNS server that answers authoritative queries and the data pipeline which takes changes made by our customers to DNS records and distributes them to our edge machines across the globe.

DNS Data Flow

The rough architecture of the system can be seen above. We store customer DNS records and other origin server information in a central database, convert the Continue reading

US dismantles Kelihos botnet after Russian hacker’s arrest

The arrest last week of a Russian man in Spain was apparently for his role in a massive spam botnet and not related to an ongoing investigation into foreign tampering with last year's U.S. election.The botnet, called Kelihos, has enslaved hundreds of thousands of computers, and distributed spam and malware to users across the globe. However, the U.S. has taken action to dismantle the illegal operation, the Department of Justice said on Monday.The arrest of 36-year-old Peter Yuryevich Levashov, the botnet's alleged operator, was at first thought to be related to the ongoing U.S. investigation of presidential election-related hacking, but the DOJ said on Monday that wasn't the case.To read this article in full or to leave a comment, please click here
