176 Steps Closer To The Mythical All-Flash Datacenter

We have nothing against disk drives. Seriously. And in fact, we are amazed at the amount of innovation that continues to go into the last electromechanical device still in use in computing, which from a commercial standpoint started out with the tabulating machines created by Herman Hollerith in 1884 and used to process the 1890 census in the United States, thus laying the foundation of International Machines Machines. …

Tagging commands on Linux

Tags provide an easy way to associate strings that look like hash tags (e.g., #HOME) with commands that you run on the command line. Once a tag is established, you can rerun the associated command without having to retype it. Instead, you simply type the tag. The idea is to use tags that are easy to remember for commands that are complex or bothersome to retype.Unlike setting up an alias, tags are associated with your command history. For this reason, they only remain available if you keep using them. Once you stop using a tag, it will slowly disappear from your command history file. Of course, for most of us, that means we can type 500 or 1,000 commands before this happens. So, tags are a good way to rerun commands that are going to be useful for some period of time, but not for those that you want to have available permanently.To read this article in full, please click here

Top metrics for effective multicloud management

When it comes to effectively managing a multicloud environment, there are a ton of network and application metrics that enterprise customers should be watching.Among enterprises, the trend is toward multicloud environments, which can include workloads running on-premises and in public clouds run by multiple cloud providers such as AWS, Microsoft Azure, IBM/Red Hat, Google Cloud Platform and others. Gartner predicts by 2021, more than 75% of midsize and large organizations will have adopted some form of a multicloud and/or hybrid IT strategy. Likewise, IDC predicts that by 2022, more than 90% of enterprises worldwide will be relying on a mix of on-premises/dedicated private clouds, multiple public clouds, and legacy platforms to meet their infrastructure needs.To read this article in full, please click here

Combining Snyk Scans in Docker Desktop and Docker Hub to Deploy Secure Containers

Last week, we announced that the Docker Desktop Stable release includes vulnerability scanning, the latest milestone in our container security solution that we are building with our partner Snyk. You can now run Snyk vulnerability scans directly from the Docker Desktop CLI.  Combining this functionality with Docker Hub scanning functionality that we launched in October provides you with the flexibility of including vulnerability scanning along multiple points of your development inner loop, and provides better tooling for deploying secure applications.

You can decide if you want to run your first scans from the Desktop CLI side, or from the Hub.  Customers that have used Docker for a while tend to prefer starting from the Hub. The easiest way to jump in is to configure the Docker Hub repos to automatically trigger scanning every time that you push an image into that repo. This option is configurable for each repository, so that you can decide how to onboard these scans into your security program. (Docker Hub image is available only for Docker Pro and Team subscribers, for more information about subscriptions visit the Docker Pricing Page.)

Once you enable scanning, you can view the scanning results either Continue reading

History of Cable Networks with Rouzbeh Yassini

Cable networks account for the majority of the connectivity at the network edge. Given we started with dial-up over plain old telephone lines, and then with DSL, and were promised “ATM to the home,” how did cable networks grab the edge? Rouzbeh Yassini joins Russ White and Donald Sharp to give us the history of cable networks.

Review: CPLAY2air Wireless CarPlay Adapter

In late September, I was given a CPLAY2air wireless CarPlay adapter as a gift. Neither of my vehicles support wireless CarPlay, and so I was looking forward to using the CPLAY2air device to enable the use of CarPlay without having to have my phone plugged into a cable. Here’s my feedback on the CPLAY2air device after about six weeks of use.

In general, the device works reasonably well. Setup with the factory radio in my GMC Sierra truck was pretty straightforward, and only took a few minutes. Since then, the device connects to my phone every time I start the vehicle, and all CarPlay functions—music, maps, Siri, sending/reading messages, etc.—all work as expected. I can leave my phone in my pocket and still gain all the benefits of CarPlay, which is incredibly convenient.

The CPLAY2air is not without a few caveats, however. The wireless connection between the CPLAY2air and my iPhone does introduce some noticeable latency. When switching music tracks, for example, it will take between one and three seconds to stop playing the old track and start playing the new track. (By comparison, the same operation using traditional wired CarPlay is nearly instantaneous.) Similarly, when talking on Continue reading

Bienvenue Cloudflare France! Why I’m helping Cloudflare grow in France

I am incredibly excited to announce that I have joined Cloudflare as its Head of France to help build a better Internet and expand the company’s growing customer base in France. This is an important milestone for Cloudflare as we continue to grow our presence in Europe. Alongside our London, Munich, and Lisbon offices, Paris marks the fourth Cloudflare office in the EMEA region. With this, we’ll be able to further serve our customers’ demand, recruit local talent, and build on the successes we’ve had in our other offices around the globe. I have been impressed by what Cloudflare has built in EMEA including France, and I am even more excited by what lies ahead for our customers, partners, and employees.

Born in Paris and raised in Paris, Normandie and Germany, I started my career more than 20 years ago. While a teenager, I had the chance to work on one of the first Apple IIe’s available in France. I have always had a passion for technology and continue to be amazed by the value of its adoption with businesses large and small. In former roles as Solution Engineer Continue reading

COVID-19 Cyberthreat and Malware Updates

It has been over three months since our last report on COVID-19–themed attacks [1]. During this period, the tragedy of the COVID-19 pandemic has continued to dominate our daily livesfe. On the digital virus side, sSince our lastthat report [1, ] we’ have been closely tracking the cyberthreat landscape that leveraging leverages the COVID-19 themes. In the last report, we discovered that the majority of the attacks were involved infostealers. The oIn observations made from over the past two months,  witnessed similar infostealers1 as reported in [ again played a key role1]. HoweverIn the meanwhile, we also detected other threats not that we hadn’t seen earlier, such as the Emotet campaign and remote access Trojan (RAT) attacks.  

In this blog post, we first present the our most recent telemetry data, as reported by some VMware customers,, in order to exhibit highlight the diversity and magnitude of the attacks. Next, we investigate the Emotet campaign, as it is the most dominant wave seen in this period. More specifically, we analyze one of the samples from the campaign to reveal the tactics, techniques, and procedures (TTPs) used in the attack, and discuss how the Emotet payload variant is different from the one we reported recently [2].2

Cisco Project Bridges Kubernetes and SD-WAN to Speed Microservice Messaging

SD-WAN ( software-defined networking in a wide area network) and Kubernetes are two major technological developments of interest for businesses on the journey toward digital transformation. SD-WAN extends the SDN feature programmable network and automation to the WAN networks. And Kubernetes has largely adopted a containerized application orchestrator that has solid API architecture, autoscaling, deep monitoring, and load balancing capabilities for dynamic and distributed infrastructures. Many companies are using them together, given that business applications are distributed to different data centers and edge cloud locations. Here, different Kubernetes clusters are connected to end-user applications and workloads, and SD-WAN is used to connect all the clusters and end users. Sagar Nangare Sagar Nangare is technology blogger, focusing on data center technologies (Networking, Telecom, Cloud, Storage) and emerging domains like Edge Computing, IoT, Machine Learning, AI). He is currently serving Calsoft Inc. as Digital Strategist. He is based in Pune. You can reach to him on Twitter @sagarnangare. But there are still gaps in this amalgamated solution. SD-WAN is used mostly on the public internet, which has different performances in different parts of the world. When we deploy microservice-based applications there may be cases where some microservices may have specific latency requirements Continue reading
