IDG Contributor Network: The return of the infrastructure engineer

Corporate digital strategy—whether it involves the cloud, the Internet of Things or other technologies—has presented new opportunities for infrastructure engineering. The infrastructure engineer, traditionally relegated to hardware provisioning and maintenance, is now an integral part of solution design and delivery. But this shift entails new expectations along with new demand.The shift towards cloud-based, software-defined infrastructure requires today’s infrastructure engineer to marry traditional, specialized depth in a technology tower (e.g., network) with architectural breadth across towers. That doesn’t mean a network engineer needs equivalent expertise in storage and hosting technologies, but it does mean engineers have to understand how network, storage and hosting technologies (as well as software) interact and integrate to deliver a business outcome. As more core engineering activities in each tower become automated, engineers will become more focused on the configuration and orchestration of technologies to deliver seamless service performance.To read this article in full or to leave a comment, please click here

Is web-scale networking secure? This infographic breaks it down.

At Cumulus Networks, we take a lot of pride in the fact that web-scale networking using Cumulus Linux can have an immense impact on an organization’s ability to scale, automate and even reduce costs. However, we know that efficiency and growth are not the only things our customers care about.

In fact, many of our customers are interested first and foremost in the security of web-scale networking with Cumulus Linux. Many conclude that a web-scale, open environment can be even more secure than a closed proprietary one. Keep reading to learn more or scroll to the bottom to check out our infographic “The network security debate: Web-scale vs. traditional networking”

Here are some of the ways web-scale networking with Cumulus Linux keeps your data center switches secure:

  • Cumulus Linux uses the same standard secure protocols and procedures as a proprietary vendor: For example, Openssh is used by both traditional closed vendors and Cumulus Linux. The standardized MD5 is used for router authentication, and Cumulus supports management VRF.
  • Web-scale networking has more “eyes” on the code with community support: Linux has a large community of developers from different backgrounds and interests supporting the integrity of the code. Since an entire community of Continue reading

IDC predicts the collapse of the Windows Phone by 2020

Microsoft’s mobile OS is tracking to eventually drop to 0.1 percent market share, and the proposed Surface Phone line expected next year won't do anything to stop that decline. That's the conclusion from IDC, which just released its latest Worldwide Quarterly Mobile Phone Tracker. It puts global smartphone year-over-year growth in 2016 at a paltry 0.6 percent That's a major drop from the 10.4 percent year-over-year growth in 2015. + Also on Network World: When it comes to security, Android is the new Windows + However, that's the total market. For just 4G smartphones, IDC predicts a 21.3 percent year-over-year growth globally for 2016, reaching 1.17 billion units. Much of this growth is coming from emerging markets, such as Asia/Pacific—excluding Japan—Latin America, Central and Eastern Europe, and the Middle East and Africa. Mature markets such as the U.S., Canada, Japan and Western Europe are further along the 4G adoption curve, so the growth is slower.To read this article in full or to leave a comment, please click here

Amazon accelerates and simplifies its cloud infrastructure offering

Amazon Web Services continued to push its infrastructure offering forward on Wednesday with the launch of upgrades to its existing instance types and new tools for simplifying and accelerating computation tasks in its public cloud.AWS CEO Andy Jassy unveiled a new Elastic GPUs feature for the Elastic Compute Cloud (EC2) that will let developers add flexible acceleration using parallel processing for their applications.On top of that, Amazon launched a new Lightsail service that’s aimed at giving customers an easy way to spin up a straightforward virtual private server without having to orchestrate a fleet of different AWS services. Finally, the company also unveiled upgrades to its burstable, memory intensive, high I/O, and compute intensive instances.To read this article in full or to leave a comment, please click here

Python Basics – Part 2 cont…

4.Tuples

A tuple is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas in a list, elements can be changed. A tuple is created by placing all the items (elements) inside a parentheses ()

  • We generally use tuple for different datatypes and list for homogeneous similar datatypes.
  • Since tuple are immutable, means value can not be changed.
  • Tuples that contain immutable elements can be used as key for a dictionary. With list, this is not possible.
  • If you have data that doesn’t change, implementing it as tuple will guarantee that it remains write-protected.

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses)

CODE:

tuple1

OUTPUT:

tuple1out

 

 

5 .Dictionary

Python dictionary is an unordered set of key:value pairs , with the requirement that the keys are unique (within one dictionary). A pair of braces creates an empty dictionary: {}.Dictionary have no concept of order among elements.

Keys are unique within a dictionary while values may not be.The values Continue reading

Amazon’s cloud will be half way to 100% renewable power by end of next year

Amazon Web Services is marching toward powering its global cloud footprint completely with renewable energy, with plans to be half way to the goal by the end of next year.As of April 2015, the company was a quarter of the way to its goal of using 100% renewable energy. One of its 14 regions – in Oregon – already runs completely on green power. At the AWS re:Invent conference this week,  VP and Distinguished Engineer James Hamilton said the company is now 40% of the way to its goal and hopes to be 45% by the end of this year. By the end of next year it hopes to be half way there.+ MORE AT NETWORK WORLD: Cool products at AWS re:Invent | A peek inside Amazon’s massive cloud, from global footprint to custom built silicon +To read this article in full or to leave a comment, please click here

Senators fail to stop new rules allowing US law-enforcement hacking

Three senators' efforts to stop a major expansion of U.S. law enforcement agencies' hacking powers has failed for now.Proposed changes to Rule 41, the search-and-seizure provision in the Federal Rules of Criminal Procedure, will go into effect Thursday barring any last-minute action in Congress. The rules change will give U.S. law enforcement agencies the authority to cross jurisdictional lines and hack computers anywhere in the world during criminal investigations. Until now, the rules, in most cases, prohibited federal judges from issuing a search warrant outside their jurisdictions. To read this article in full or to leave a comment, please click here

AWS launches FPGA-based cloud instances to accelerate complex applications

Amazon Web Services gave its cloud customers a set of new infrastructure capabilities aimed at making its compute offering faster for complex applications that benefit from hardware acceleration.The F1 instance type, which entered beta on Wednesday, lets companies deploy applications that are accelerated by field-programmable gate arrays (FPGAs). FPGAs allow users to program hardware to perform a particular task quicker than a general-purpose processor would be able to.AWS CEO Andy Jassy positioned the new instances as a way to democratize access to the hardware needed to optimize speed for particular applications. Several other public cloud providers have turned to specialized hardware like FPGAs to try and accelerate the speed of their offerings.  To read this article in full or to leave a comment, please click here

Lenovo Drives HPC From The Middle Ground

While we all spend a lot of time talking about the massive supercomputers that cultivate new architectures, and precisely for that reason, it is the more modest cluster that makes use of these technologies many years hence that actually cultivates a healthy and vibrant HPC market.

Lenovo picked up a substantial HPC business when it acquired IBM’s System x server division two years ago and also licensed key software, such as the Platform Computing stack and the GPFS file system, to drive its own HPC agenda. The Sino-American system maker has been buoyed by higher volume manufacturing thanks to the …
