Coming soon: On-premises 5G gear for enterprises

With all major mobile carriers expected to offer 5G this year, enterprises that want to take advantage of this next-gen mobile data service need to start thinking about how to support it on site.Anticipation is keen for 5G, given that it promises to deliver faster speeds and lower latency than the current premium wireless technology, 4G LTE. Ideally, 5G networks could deliver fast internet to areas of the country where wired broadband is unavailable, and more reliable connections to a variety of devices including not only computers and smartphones but also appliances, automobiles and security systems. But to use these services as a WAN option, businesses need hardware that can connect it to their existing wired and wireless LANs.To read this article in full, please click here

SD-WAN creates new security challenges

SD-WAN products have been available for the better part of five years. Early adopters of the technology focused primarily on transport-related issues such as replacing or augmenting MPLS with broadband. As any technology matures and moves out of the early adopter phase, the buying criteria changes — and SD-WAN is no different.In 2018, a ZK Research survey asked respondents to rank SD-WAN buying criteria, and security came out as the top response, well ahead of technology innovation and price. (Note: I am employee of ZK Research.) To better understand this trend and what it means to network professionals, I sat down with Fortinet’s executive vice president of products and solutions, John Maddison, who sets the company’s product strategy, making him well versed in both SD-WAN and security.To read this article in full, please click here

Dell EMC speeds up backups and restores in its storage appliances

Dell EMC has introduced new software for its Data Domain and Integrated Data Protection Appliance (IPDA) products that it claims will improve backup and restore performance from anywhere from 2.5 times to four times the previous version.Data Domain is Dell EMC’s purpose-built data deduplicating backup appliance, originally purchased by EMC long before the merger of the two companies. The IPDA is a converged solution that offers complete backup, replication, recovery, deduplication, with cloud extensibility.Performance is the key feature Dell is touting with Data Domain OS 6.2 and IDPA 2.3 software. Dell says Data Domain on-premises restores are up to 2.5 times faster than prior versions, while data restoration from the Amazon Web Services (AWS) public cloud to an on-premises Data Domain appliance can be up to four times faster.To read this article in full, please click here

How to make CI/CD with containers viable in production

Continuing Integration and Continuing Development (CI/CD), and containers are both at the heart of modern software development. CI/CD developers regularly break up applications into microservices, each running in their own container. Individual microservices can be updated independently of one another, and CI/CD developers aim to make those updates frequently.

This approach to application development has serious implications for networking.

There are a lot of things to consider when talking about the networking implications of CI/CD, containers, microservices and other modern approaches to application development. For starters, containers offer more density than virtual machines (VMs); you can stuff more containers into a given server than is possible with VMs.

Meanwhile, containers have networking requirements just like VMs do, meaning more workloads per server. This means more networking resources are required per server. More MAC addresses, IPs, DNS entries, load balancers, monitoring, intrusion detection, and so forth. Network plumbing hasn’t changed, so more workloads means more plumbing to instantiate and keep track of.

Containers can live inside a VM or on a physical server. This means that they may have different types of networking requirements than traditional VMs, (only talking to other containers within the same VM, for example) than other workloads. Continue reading

IDG Contributor Network: Named data networking: names the data instead of data locations

Today, connectivity to the Internet is easy; you simply get an Ethernet driver and hook up the TCP/IP protocol stack. Then dissimilar network types in remote locations can communicate with each other. However, before the introduction of the TCP/IP model, networks were manually connected but with the TCP/IP stack, the networks can connect themselves up, nice and easy. This eventually caused the Internet to explode, followed by the World Wide Web.So far, TCP/IP has been a great success. It’s good at moving data and is both robust and scalable. It enables any node to talk to any other node by using a point-to-point communication channel with IP addresses as identifiers for the source and destination. Ideally, a network ships the data bits. You can either name the locations to ship the bits to or name the bits themselves. Today’s TCP/IP protocol architecture picked the first option. Let’s discuss the section option later in the article.To read this article in full, please click here

Get TotalAV Essential AntiVirus for $19.99 (80% off)

The term “computer virus” calls to mind imagery of pathogenic creepy-crawlies bringing down a device’s operating system, their flagella wriggling as they multiply into hordes that infiltrate its chips and wires. And while it’s true that our computers can be infected with literal biological bacteria like staphylococci, per Science Illustrated, the threat of malicious codes and programs intent on corrupting data and files looms far larger: According to a recent study from the University of Maryland’s Clark School of Engineering, attacks on computers with internet access is virtually ceaseless, with an incident occurring every 39 seconds on average, affecting a third of Americans every year.

What is hyperconvergence?

Hyperconvergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data center complexity and increase scalability. Hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking, and they typically run on standard, off-the-shelf servers. Multiple nodes can be clustered together to create pools of shared compute and storage resources, designed for convenient consumption.The use of commodity hardware, supported by a single vendor, yields an infrastructure that's designed to be more flexible and simpler to manage than traditional enterprise storage infrastructure. For IT leaders who are embarking on data center modernization projects, hyperconvergence can provide the agility of public cloud infrastructure without relinquishing control of hardware on their own premises.To read this article in full, please click here
