Dell, VMware Team Up To Tackle The Hybrid Cloud

As enterprises shift more of their workloads into public clouds and grow out their multicloud strategies – many are using three or more public clouds for their applications and data to as much  protect them against problems with the cloud provider as to take advantage of particular strengths that each cloud provider offer – there can be the tendency to think that many will end up putting everything in the cloud. …

2019 Customer Innovation awards: 6 Stories of Transformation in the Enterprise

We are thrilled to honor six of our enterprise customers with the 2019 Docker Customer Innovation Award today at DockerCon. We launched the awards last year to recognize customers who stand out for how they are using  Docker Enterprise to drive transformation within IT and their business.

These are companies ranging from cruise lines to established “brick and mortar” enterprises, some of whom have been in business for well over 100 years. These are their stories.

Creating Exceptional Experiences: Carnival Corporation

         

Carnival’s first commitment is to creating fun, memorable and safe experiences for its guests. As the largest cruise line in the world, Carnival hosts over 12 million customers annually on 110 ships and at 15 resorts. Technology plays a key role in providing a world-class consistent customer experience.

Carnival leverages Docker Enterprise to build, run and update over 300 services on its new Medallion System, a necklace or wrist band IoT token unique to each passenger used to pay for drinks or as a key to your room. Adding or changes services, or testing new ones, is easy with the Docker Enterprise platform. The system is running on two ships today, with plans to expand Continue reading

Heavy Networking 446: How Open Systems Integrates Security And SD-WAN As A Service

Open Systems integrates security and SD-WAN as a service, including next-gen firewalls and Web gateways. They're the sponsor for today's Heavy Networking podcast. We discuss Open Systems' architecture, how it applies SD-WAN and security policies to traffic, and how Open Systems differentiates itself in this crowded market.

The post Heavy Networking 446: How Open Systems Integrates Security And SD-WAN As A Service appeared first on Packet Pushers.

Commentary: We’re stuck with 40 years old technology

One of my readers sent me this email after reading my Loop Avoidance in VXLAN Networks blog post:

Not much has changed really! It’s still a flood/learn bridged network, at least in parts. We count 2019 and talk a lot about “fabrics” but have 1980’s networks still.

The networking fundamentals haven’t changed in the last 40 years. We still use IP (sometimes with larger addresses and augmentations that make it harder to use and more vulnerable), stream-based transport protocol on top of that, leak addresses up and down the protocol stack, and rely on technology that was designed to run on 500 meters of thick yellow cable.

How to shop for enterprise firewalls

Firewalls have been around for years, but the technology keeps evolving as the threat landscape changes. Here are some tips about what to look for in a next-generation firewall (NGFW) that will satisfy business needs today and into the future.Don't trust firewall performance stats Understanding how a NGFW performs requires more than looking at a vendor’s specification or running a bit of traffic through it. Most firewalls will perform well when traffic loads are light. It’s important to see how a firewall responds at scale, particularly when encryption is turned on. Roughly 80% of traffic is encrypted today, and the ability to maintain performance levels with high volumes of encrypted traffic is critical.To read this article in full, please click here

Cisco goes all in on WiFi 6

Cisco has taken the wraps off a family of WiFi 6 access points, roaming technology and developer-community support all to make wireless a solid enterprise equal with the wired world.“Best-effort’ wireless for enterprise customers doesn’t cut it any more. There’s been a change in customer expectations that there will be an uninterrupted unplugged experience,” said Scott Harrell, senior vice president and general manager of enterprise networking at Cisco. “It is now a wired first world.” More about 802.11ax (Wi-Fi 6) Why 802.11ax is the next big thing in wireless FAQ: 802.11ax Wi-Fi Wi-Fi 6 (802.11ax) is coming to a router near you Wi-Fi 6 with OFDMA opens a world of new wireless possibilities 802.11ax preview: Access points and routers that support Wi-Fi 6 are on tap Bringing a wired first enterprise world together is one of the drivers behind a new family of WiFi 6-based access points (AP) for Cisco’s Catalyst and Meraki portfolios.  WiFi 6 (802.11ax) is designed for high-density public or private environments. But it also will be beneficial in internet of things (IoT) deployments, and in offices that use bandwidth-hogging applications like videoconferencing.To read this article in full, please click here

IDG Contributor Network: Robots extend the scope of IoT applications

Robots and IoT devices are similar in that they both rely on sensors to understand their environment, rapidly process large streams of data and decide how to respond.That’s where the similarities end. Most IoT applications handle well-defined tasks, whereas robots autonomously handle anticipated situations. Let’s consider both from six different vectors:1. Sensor IoT – Binary output from stationary sensor. “Is the door open or closed?” Robots – Complex output from multiple sensors. “What is in front of me? How do I navigate around it?” 2. Processing IoT – Simple data stream of signals handled with well-known programming methods. Robots – Large complex data streams handled by neural network computing. 3. Mobility IoT – Sensors are stationary and signal processing is done in the cloud. Robots – The sensor laden robot is mobile and signal processing is done locally and autonomously. 4. Response IoT – The action to take in response to a situation is well defined. Robots – Multiple actions could be taken in response to a situation. 5. Learning IoT – The application typically does not ‘evolve’ on its own and develop new features. Robots – Machine learning and other techniques are used to let Continue reading

Common Componentry Is The Key to Edge Architectures

The edge has caught the imagination of IT vendors, who envision a place well outside of the confines of the central datacenter but not quite in the cloud where the vast amounts of data that are being generated by billions of devices, systems and sensors can be quickly captured, stored, processed and analyzed in as close to real time as possible. …

About that Easy Button …

We love layers and abstraction. After all, building in layers and it’s corollary, abstraction, are the foundation of large-scale system design. The only way to build large-scale systems is to divide and conquer, which means building many different component parts with clear and defined interaction surfaces (most often expressed as APIs) and combining these many different parts into a complete system. But abstraction, layering, and modularization have negative aspects as well as positive ones. For instance, according to the State/Optimization/Surface triad, any time we remove state in order to control complexity, we either add an interaction surface (which adds complexity) or we reduce optimization.

Another impact of abstraction, though, is the side effect of Conway’s Law: “organizations which design systems … are constrained to produce designs which are copies of the communication structures of these organizations.” The structure of the organization that designs a system is ultimately baked into the modularization, abstraction, and API schemes of the system itself.

To take a networking instance, many networks use one kind of module for data centers and another for campuses. The style of network built in each place, where the lines are between these different topological locations in the network, the Continue reading
