Technology Short Take 151

Welcome to Technology Short Take #151, the first Technology Short Take of 2022. I hope everyone had a great holiday season and that 2022 is off to a wonderful start! I have a few more links than normal this time around, although I didn’t find articles in a couple categories. Don’t worry—I’ll keep my eyes peeled and my RSS reader ready to pull in new articles in those categories for next time. And now for the content!

Networking

• Mike Fiedler explores differences in ways for container-to-container communication to occur.
• Aidan Steele examines how VPC sharing could potentially improve security and reduce cost.
• What do you think microsegmentation means?
• Nick Schmidt talks about using GitOps with the NSX Advanced Load Balancer.

Servers/Hardware

• The Next Platform takes a look at Amazon’s Graviton3 processor.
• Ru Singh provides a review of his M1-based MacBook Air.
• Here’s a great review of the Framework laptop.
• Losing to Apple—whose M-series chips are widely regarded as faster and more efficient than Intel’s chips—has apparently stung the chip giant into revving up the innovation engine. These details on their 12th-generation H processors shows that Intel appears to be intent to regain the lead. Time will tell how successful they Continue reading

Video: Machine Learning Techniques

After Javier Antich walked us through the AI/ML hype and described the basics of machine learning it was time for a more thorough look at:

• Machine learning techniques, including unsupervised learning (clustering and anomaly detection), supervised learning (regression, classification and generation) and reinforced learning
• Machine learning implementations, including neural networks, deep neural networks and convolutional neural networks.

Edge computing in 2022: Double-digit growth

Worldwide spending on edge computing is expected to reach $176 billion in 2022, an increase of 14.8% over last year, according to new figures from analyst IDC.Edge computing started out rather modest in its use cases but has quickly expanded across industries and scope. Five years ago an edge network was a few mid-range servers in a ruggedized container. Now Nvidia and Lenovo are deploying GPU-based AI systems.How to choose an edge gateway “If we have learned anything over the last two years, the ability to quickly adapt to rapidly changing conditions is critical to business success. Organizations investing in edge computing combined with AI and modern application design will have an advantage when it comes to tackling whatever challenge comes next,” according to Dave McCarthy, research vice president for Cloud and Edge Infrastructure Services at IDC.To read this article in full, please click here

Hedge 115: Mat Duggan and DevOps

Devops is the new normal—but, far too often, operations folks (like network engineers) are expected to become full-on developers, and developers are expected to understand operations in ways they never had to before. Mat Duggan joins Tom Ammon and Russ White to discuss why operations is not development IT

New Cisco switch brings more networking features to the edge

Cisco is expanding its Catalyst family of switches for enterprises that need to blend industrial and operational technology (OT) systemsThe the ruggedized Catalyst Industrial Ethernet 9300 1RU rack-mountable switch is based on the same programmable Unified Access Data Plane (UADP) ASIC found in other Catalyst 9000 and features 28 Gigabit Ethernet ports. Up to eight of the units can be stacked together and managed as one system.SD-WAN buyers guide: Key questions to ask vendors The 9300 runs the same IOS XE operating system as other Catalyst boxes and can be centrally  controlled via DNA Center, Cisco’s principal networking-control platform that features myriad services from analytics, network management, and automation capabilities to assurance setting, fabric provisioning, and policy-based segmentation.To read this article in full, please click here

Backing up a database depends on how it’s delivered

How you back up your database depends three factors: how the database is delivered to you, the backup logistics of the database, and the recovery time objective (RTO) and the recovery point objective (RPO) you are attempting to meet. This article covers how the database is delivered.There are three ways databases can be delivered: as software on a server you own; as platform-as-a-service (PaaS); and as a serverless service. Let’s take a look at them.[Get regularly scheduled insights by signing up for Network World newsletters.] Traditional database software Until a few years ago the way all databases were delivered was by buying a license for a product and installing it on a server or VM of your choice. You were responsible for everything, including the security and administration of the server, the storage, the application itself, and (of course) the backup of the database. To read this article in full, please click here

VMware Network Automation with NSX-T 3.2 and vRealize Automation

VMware Network Automation combines the modern microservices architecture of vRealize with VMware NSX network virtualization to enable rapid application rollout. The solution automates VMware NSX via VMware vRealize Automation to deliver complete workload lifecycle automation through networking, compute, and security services that make it simple to template, provision, and update complete environments. That, in turn, enables businesses to accelerate application delivery and drive overall agility.

The latest iterations of vRealize Automation native integration with NSX-T features include multiple new capabilities, such as support for NSX-T Federation, distributed firewall configurations from NSX-T, a shared gateway across on-demand networks, and many others.

In this post, we will provide an overview of the feature-set available with this native integration. The post doesn’t aim to be exhaustive, so don’t hesitate to look at the vRealize Automation documentation for more details.

Setting up the Environment

The native integration allows for consumption of NSX-T constructs from vRealize Automation after a simple configuration.

The goal is for the cloud admin to be able to offer users a self-service catalog, through Service Broker that enables the deployment of complex topologies with consistent governance policies across the cloud — all while abstracting the underlying infrastructure and its complexity from Continue reading
