When Hardware Drives Software Upgrades

8006701A-85B8-4391-BD36-487B35755676

What’s your favorite version of Microsoft Windows? Is it Windows 10? Maybe it’s Windows XP? Windows 95? Odds are good that you have one version you appreciated more than most. Windows XP, Windows 7, and Windows 10 tend to rank high on the list. Windows ME and Windows 8 seem to rank pretty low. Yet, for all their impressive love and all the users clinging to them we don’t really use anything other than Windows 10 any more.

You might be tempted to say that the OS isn’t supported any longer so there’s no reason to run it. Yet we still drive vehicles that are no longer under warranty. We still buy classic cars that are older than we are and put parts in them to keep them running. Why is software different? What drives us to keep needing to upgrade our programs?

You might be shocked to learn that the most popular reason to upgrade software is, in fact, driven by hardware. It’s not the memory requirements or the fancy new user interface that drives people to move to the new platform. More often than not it’s because a new piece of hardware has requirements that only work on Continue reading

Cloud Networking As A Service Case Study With Koch – Packet Pushers LiveStream With Alkira (Video 3)

Koch Business Solutions provides IT services for businesses within Koch Industries. The company implemented a cloud-first modernization plan several years ago. At the time, the organization built transport hubs to get huge datasets and workloads into the cloud, but realized it was still coupled to a data center approach. The Packet Pushers’ Drew Conry-Murray speaks […]

Google Hints About Its Homegrown TPUv4 AI Engines

Google may be buying heavens only knows how many GPUs to run HPC and AI workloads on its eponymous public cloud, and it may have talked recently about how it is committed to the idea of pushing the industry to innovate at the SoC level and staying out of designing its own compute engines, but the company is still building its own Tensor Processing Units, or TPUs for short, to support its TensorFlow machine learning framework and the applications it drives within Google and as a service for Google Cloud customers. …

CDN-Cache-Control: Precision Control for your CDN(s)

CDN-Cache-Control: Precision Control for your CDN(s)
CDN-Cache-Control: Precision Control for your CDN(s)

Today we are thrilled to announce our support of a new set of HTTP response headers that provide surgical control over our CDN’s caching decisions. CDN-Cache-Control allows customers to directly control how our CDN behaves without affecting the behavior of downstream or upstream caches.

You might be thinking that this sounds a lot like the Cache-Control header we all know and love. And it’s very similar! CDN-Cache-Control has exactly the same directives as the Cache-Control header. The problem CDN-Cache-Control sets out to solve is that with Cache-Control, some directives are targeted at specific classes of caches (like s-maxage for shared caches), while other directives are not targeted at controlling any specific classes of intermediary caches (think stale-while-revalidate). As these non-specific directives are returned to downstream caches, they’re often not applied uniformly. This problem is amplified as the number of intermediary caches grows between an origin and the client.

For example, a website may deploy a caching layer on the origin server itself, there might be a cache on the origin’s network, the site might use one or more CDNs to cache content distributed throughout the Internet, and the visitor’s browser might cache content as well. As the response returns Continue reading

Video: We Still Need Networking in Public Clouds

Whenever someone starts mansplaining that we need no networking when we move the workloads into a public cloud, please walk away – he has just proved how clueless he is.

He might be a tiny bit correct when talking about software-as-a-service (after all, it’s just someone else’s web site), but when it comes to complex infrastructure virtual networks, there’s plenty of networking involved, from packet filters and subnets to NAT, load balancers, firewalls, BGP and IPsec.

Internet by the people, for the people – a view from the Digital Empowerment Foundation

The Digital Empowerment Foundation believes building community networks is something everyone can do. And people are doing it. Internet connectivity may be important for our global society, but in rural India it’s a luxury not many villages have access to. Osama Manzar, the founder of the Digital Empowerment Foundation, has spent the last decades trying […]

Upbound Universal Crossplane Wants to Replace Infrastructure as Code

Crossplane, has created what it says is the first enterprise distribution of Crossplane called Bassam Tabbara, Upbound founder and CEO, in an interview. Crossplane “becomes your universal control plane that you could use, using the same style that the Kubernetes community pioneered, to manage essentially all the infrastructure that an enterprise touches from a single control plane.” UXP, then, is an open source, vendor-supported, enterprise-grade distribution of Crossplane that also adds on a layer of 24/7 support, priority bug fixes, and consultation with a subscription. UXP is available free for individual users and by subscription for larger deployments, and is a drop-in replacement for Crossplane that installs with a single command. Tabbara noted that UXP is “vendor-supported, not community-supported,” in that Upbound will “help enterprises deploy it, support it, and give them a number of features that makes it easier for them to deploy and manage it in their environment.” As a long-term supported project, UXP also lags behind Crossplane upstream to ensure reliability, and Upbound describes UXP  as “designed to help enterprises adopt a universal control plane, moving beyond infrastructure as code,” in a press statement. In the case of UXP, Crossplane is further extended with its integration with both Upbound Cloud and Upbound Registry, both of which became generally available at the same time as the release of UXP. Upbound Cloud provides teams with visibility into their UXP instances and the infrastructure being managed, giving them a place to see what is running where, and by who it was provisioned. Upbound Registry then provides a place to both publicly and privately share Crossplane Configurations, and for providers to share managed resources. “With UXB, with Upbound Cloud and Upbound Registry, we believe we have a set of products now that can actually take this approach of using control planes in the enterprise and turn it into essentially a new way of managing infrastructure,” Tabbara said. “We see this with existing customers today, maybe even replacing a lot of what they do today with tools like Terraform and infrastructure-as-code approaches and going more towards a control plane approach, or even gitOps on top of a control plane.” The big difference Tabbara sees in all of this is that, by taking the API-driven approach rather than relying on templates, as with infrastructure as code, Crossplane and UXP can deliver a more scalable experience to managing infrastructure across large and varied environments. He explained that part of the appeal of Crossplane lies in the fact that teams can use the same Kubernetes-based tools and approaches that they are already using to deploy software to provision and manage infrastructure. Sponsor Note LaunchDarkly is a feature management platform that empowers all teams to safely deliver and control software through feature flags. By separating code deployments from feature releases, LaunchDarkly enables you to deploy faster, reduce risk, and iterate continuously. “If you are using Helm, or kustomize, or if you’re using literally any of the tools that people are deploying and love and use today with Kubernetes, as a container orchestrator, those tools work exactly in the same way,” said Tabbara. “When you’re using Kubernetes plus Crossplane to manage the rest of the cloud infrastructure and deployments across clouds and hybrid clouds, those tools work exactly in the same way. They are using Crossplane APIs that are extensions of Kubernetes extensions of the Kubernetes control plane.” Following the most recent KubeCon+CloudNativeCon, there were some
