IDG Contributor Network: How will the cloud be able to handle the emergence of IoT

Cloud computing and the Internet of Things (IoT) have spent the last several years in a sort of maximum-acceleration race where they’ve lapped the other players several times over and have only one another to measure against.IOT Expansion and Cloud Capacity Neither is slowing down, particularly the IoT. According to analysis firm Gartner, the number of IoT devices will hit 20.8 billion by 2020. The world population is expected to reach 8 billion in 2020, meaning there will be 2.5 IoT devices per person on the entire planet. In 2016, the IoT was growing at the rate of 5.5 million new things getting connected every day.To read this article in full or to leave a comment, please click here

WHOIS going to be at the Grace Hopper Celebration?

Ubuntu us are doing the round trip! It’s time to live - WAN you arrive at GHC, come meet us and say HELO (we love GNU faces, we’ll be very api to meet you). When you’re exhausted like IPv4, git over to the Cloudflare corner to reboot –– we’ll have chargers and Wi-Fi (it’s not a SYN to REST). R booth can be your ESC. Then Thursday morning we’re hosting a breakfast bash with Zendesk –– it will be quite the Assembly, you should definitely Go, compile a bowl of serial, drink a bit of CIDR or a cup of tee.

I’m also speaking at 1:30PM on Wednesday in OCCC W414 hashing out encryption and updates for IoT –– DES should be a fun session.

ACK! I did NAT tell you how to find us. Check for sum women in capes a few hops away from the booths with the lava LAMP stack. I'm the one with cURLs.

In D air! Excited to LANd. C you soon.

Why submarine cable , why not satellite ?

Why submarine/subsea cables rather than satellite. Story between my friend who is from finance background and myself.     Today, one of my friends who is totally foreigner to our industry,  visited me at home. It was a family dinner actually and as I said, He is not a network engineer but just a curios […]

Cisco Virtual Router for Cloud Services : Cisco CSR1000v

Today I am going to talk about the Cisco CSR1000v router used for the cloud services. With the help of Cisco CSR 1000v router you will able to connect the public and the private clouds and use the applications smoothly.

What is the purpose of Cisco CSR 1000v routers ?
With the help of Cisco CSR 1000V we can use the cloud-based networking and security issues to access the public and private clouds applications. Cisco CSR1000v uses the same type of Cisco IOS Software platform that is inside the Cisco Integrated Services Router (ISR) and Aggregation Services Router (ASR) product families, If you talk about the Cisco CSR1000v, the virtual router contains the features like routing, VPN, firewall, Network Address Translation (NAT), QoS, application visibility, failover, and WAN optimization. These functions empower enterprises and cloud providers to build highly secure, optimised, scalable, and consistent hybrid networks.

If Cisco CSR 1000v is a virtual router then how and where it runs ?
Well Cisco CSR1000v is a virtual router and run on VM. for running the Cisco CSR1000v you should have a UCS server where VM will be installed and on top of the VM, Cisco CST 1000v router IOS image will be Continue reading

BrandPost: An SD-WAN Can Cure Your Security Blues

Cyber security remains a hot topic with nearly every IT and business leader that I speak with. In particular, there seems to be an intensified focus on network security. Security is typically deployed in layers (network, compute and application), and I expect that model to continue in the short-term, but given the fact that many of the building blocks of digitization, such as IoT and the cloud, are network-centric, there should be a stronger focus on leveraging the network and network-based security to protect the organization.Nowhere in the network has there been more change than in the wide area network (WAN), so it stands to reason that as legacy WANs evolve into software-defined WANs, it must play an increasingly critical role in securing the enterprise.  Below are my top five recommendations to better secure your organization with an SD-WAN.To read this article in full or to leave a comment, please click here

How to kill your network with Ansible

Aside from being a user, I write about Ansible and try to help others to understand how it works. A few days ago I was answering questions from other Ansible users. Someone was having trouble figuring out why the ios_config module didn’t apply his template correctly. I explained what was wrong with the template, afterwards I thought about the issue some more and realized that the error could potentially be really dangerous. As in a game-over-level-event for your employment dangerous. Continue reading

North Korea Gets New Internet Link via Russia

This past weekend, North Korea expert Martyn Williams and I spotted the activation of a new internet path out of North Korea.  At 09:07:51 UTC on 1 October 2017, the country’s single internet provider, Star JV (AS131269), gained a new connection to the global internet through Russian fixed-provider Transtelecom (AS20485), often referred to as TTK.  Martyn published his analysis on the US-Korea Institute‘s 38 North blog, named after the dividing line between North and South Korea.

The internet of North Korea is very small (four BGP routes) and reportedly only accessible by a few elites in the country.  Since the appearance of AS131279 in the global routing table almost 7 years ago, Star JV has almost exclusively relied on China Unicom for its connectivity to the global internet — the only exception was its partial usage of satellite service from Intelsat between 2012 and 2013.  In light of this history, a new internet connection out of North Korea is certainly a notable development.

Unsteady Connection

At 09:07:51 UTC, TTK (AS20485) appeared as a transit provider for three of the four BGP routes announced by AS131279, namely, 175.45.176.0/24, 175.45.178.0/24, and Continue reading

Intel Gears Up For FPGA Push

Chip giant Intel has been talking about CPU-FPGA compute complexes for so long that it is hard to remember sometimes that its hybrid Xeon-Arria compute unit, which puts a Xeon server chip and a midrange FPGA into a single Xeon processor socket, is not shipping as a volume product. But Intel is working to get it into the field and has given The Next Platform an update on the current plan.

The hybrid CPU-FPGA devices, which are akin to AMD’s Accelerated Computing Units, or APUs, in that they put compute and, in this case, GPU acceleration into a single …

Will machine learning save the enterprise server business?

Nvidia and server makers Dell EMC, HPE, IBM and Supermicro announced enterprise servers featuring Nvidia’s Tesla V100 GPU. The question is, can servers designed for machine learning stem the erosion of enterprise server purchases as companies shift to PaaS, IaaS, and cloud services? The recent introduction of hardened industrial servers for IoT may indicate that server makers are looking for growth in vertical markets.There are very compelling reasons for moving enterprise workloads to Amazon, Google, IBM and other hosted infrastructures. The scalability of on-demand resources, operating efficiency at cloud-scale and security are just three of many reasons. For instance, Google has 90 engineers working on just security where most enterprises are understaffed.To read this article in full or to leave a comment, please click here

Google, Scale Computing partner for easier hybrid cloud deployment

Google has partnered with Scale Computing, developer of infrastructure software for hyper-converged systems, to make it easier to deploy Google Cloud Platform as a backup for your own data center. The two companies have created a platform called Cloud Unity, which integrates Scale’s HC3 software environment with Google Compute Engine. HC3 is a cluster software product that merges server, storage and virtualization into a single appliance for easier converged infrastructure. Also on Network World: Google develops high-capacity cloud data transfer device With HC3, you can build a cluster using Google's infrastructure instead of buying your own, thus creating a backup of your own data center in Google’s data centers. Cloud Unity creates a SD-WAN connection to your existing Scale environment, so the Google-hosted cloud version of your data center appears as just another cluster on the same LAN. It uses a VXLAN encryption between your site and Google’s data center. To read this article in full or to leave a comment, please click here

The DockerCon Hallway Track is coming to DockerCon Europe in Copenhagen. We’ve partnered with e180.co once again to deliver the next level of conference attendee networking. Together, we believe that education is a relationship, not an institution, and that a conversation can change someone’s life. After the success of our collaboration in Austin with Moby Mingle, we’re happy to be growing this idea further for Copenhagen.

DockerCon is all about learning new things and connecting with the right people. The Hallway Track will help you meet and share knowledge with community members and practitioners at the conference.
