Cisco taps into AWS for data center, cloud applications

Cisco has released a cloud-service program on its flagship software-defined networking (SDN) software that will let customers manage and secure applications running in the data center or in Amazon Web Service cloud environments.The service, Cisco Cloud ACI (application centric infrastructure) for AWS lets users configure inter-site connectivity, define policies and monitor the health of network infrastructure across hybrid environments, Cisco said.[ Check out What is hybrid cloud computing and learn what you need to know about multi-cloud. | Get regularly scheduled insights by signing up for Network World newsletters. ] Specifically, this connectivity includes an "underlay network for IP reachability (IPsec VPN) over the Internet, or through AWS Direct Connect; an overlay network between the on-premises and cloud sites that runs BGP EVPN [Ethernet VPN] as its control plane and uses Virtual Extensible LAN (VXLAN) encapsulation and tunneling as its data plane,” Cisco says.To read this article in full, please click here

You Can Now Get This Award-Winning VPN For Just $1/month

If you use the internet (which you clearly do), you likely know how important it is to protect your data in an increasingly dangerous cyber environment. But like other essential tasks that tend to be tedious (like filing taxes early and brushing your teeth for the full two minutes), most installing and running a VPN can sound unappealing to many: sure, they encrypt your internet traffic and hide your location — but they can also run frustratingly slowly, delaying the way you’d usually use the internet for entertainment and work. That’s where Ivacy VPN is different: not only will the speedy service let you browse and stream lag-free, it also offers real-time threat detection technology, removing malware and viruses at the server level. It ensures that all your downloads and devices stay totally secure, so you can stay safe online without being inconvenienced.To read this article in full, please click here

Google partners with Intel, HPE and Lenovo for hybrid cloud

Still struggling to get its Google Cloud business out of single-digit marketshare, Google this week introduced new partnerships with Lenovo and Intel to help bolster its hybrid cloud offerings, both built on Google’s Kubernetes container technology.At Google’s Next ’19 show this week, Intel and Google said they will collaborate on Google's Anthos, a new reference design based on the second-Generation Xeon Scalable processor introduced last week and an optimized Kubernetes software stack designed to deliver increased workload portability between public and private cloud environments.[ Read also: What hybrid cloud means in practice | Get regularly scheduled insights: Sign up for Network World newsletters ] As part the Anthos announcement, Hewlett Packard Enterprise (HPE) said it has validated Anthos on its ProLiant servers, while Lenovo has done the same for its ThinkAgile platform. This solution will enable customers to get a consistent Kubernetes experience between Google Cloud and their on-premises HPE or Lenovo servers. No official word from Dell yet, but they can’t be far behind.To read this article in full, please click here

Safer Internet Day 2019: Malaysia Gears Up for Cyber Wellness

Safer Internet Day is celebrated in over 100 countries each year to promote a more secure Internet. It nurtures and increases public awareness on cyber security, especially to young people across the globe, so that they become more responsible when using technology and digital gadgets. In Malaysia this year, this event was observed over one month, beginning 5 February.

The Malaysian Safer Internet Day campaign was officiated by Eddin Syazee Shith, Deputy Minister of Communication and Multimedia in Putrajaya, Malaysia. It focused on “Cyber Wellness,” with the objective to promote wellness in the digital world through healthy mental well-being and ethical social values.

The Internet Society Malaysia Chapter was a strategic partner in Safer Internet Day 2019. Together with the Ministry of Communications and Multimedia, CyberSecurity Malaysia and other stakeholders from the industry, regulators, and society, various programs were organized to promote cyber wellness, a safer Internet, and nurturing and increasing public awareness on cyber security.

The theme cyber wellness was chosen as young people today have greater access to the Internet and communication devices. Living in an “on demand” interactive digital culture where social media has become an influential platform to their social lives, youth can be exposed to Continue reading

HPE and Nutanix partner for hyperconverged private cloud systems

Hewlett Packard Enterprise (HPE) has partnered with Nutanix to offer Nutanix’s hyperconverged infrastructure (HCI) software available as a managed private cloud service and on HPE-branded appliances.As part of the deal, the two companies will be competing against each other in hardware sales, sort of. If you want the consumption model you get through HPE’s GreenLake, where your usage is metered and you pay for only the time you use it (similar to the cloud), then you would get the ProLiant hardware from HPE.If you want an appliance model where you buy the hardware outright, like in the traditional sense of server sales, you would get the same ProLiant through Nutanix.To read this article in full, please click here

Anti-lasers could give us perfect antennas, greater data capacity

Playing laser light backwards could adjust data transmission signals so that they perfectly match receiving antennas. The fine-tuning of signals like this, not achieved with such detail before, could create more capacity for ever-increasing data demand."Imagine, for example, that you could adjust a cell phone signal exactly the right way, so that it is perfectly absorbed by the antenna in your phone," says Stefan Rotter of the Institute for Theoretical Physics of Technische Universität Wien (TU Wien) in a press release.To read this article in full, please click here

802.11ax Is NOT A Wireless Switch

802.11ax is fast approaching. Though not 100% ratified by the IEEE, the spec is at the point where most manufacturers and vendors are going to support what’s current as the “final” version for now. While the spec for what marketing people like to call Wi-Fi 6 is not likely to change, that doesn’t mean that the ramp up to get people to buy it is showing any signs of starting off slow. One of the biggest problems I see right now is the decision by some major AP manufacturers to call 802.11ax a “wireless switch”.

Complex Duplex

In case you had any doubts, 802.11ax is NOT a switch.1 But the answer to why that is takes some explanation. It all starts with the network. More specifically, with Ethernet.

Ethernet is a broadcast medium. Packets are launched into the network and it is hoped that the packet finds the destination. All nodes on the network listen and, if the packet isn’t destined for them they discard it. This is the nature of the broadcast. If multiple stations try to talk at once, the packets collide and no one hears anything. That’s why Ethernet developed a collision detection Continue reading
