Service mesh integration software provider Solo.io has released into general availability (GA) version 1.8 of its Gloo Edge Kubernetes-native ingress controller and API gateway. Version 1.8 offers integration for legacy SOAP (Simple Object Access Protocol) web services and other features, as Solo seeks to improve API-centric support for scaling needs across cloud native environments. Based on the Gloo Edge now helps DevOps teams integrate decades-old SOAP through a single API. Gloo Edge 1.8’s support for SOAP is “the biggest breakout feature” of the release, blog post, Gaun described how SOAP, an XML messaging protocol from the turn of the century, “remains prevalent today for enterprise web services across a number of industries, including financial services and healthcare.” Yet, “Unfortunately, SOAP (and associated legacy middleware applications) hold back large-scale modernization efforts because there hasn’t been a viable migration approach in the market,” Gaun wrote. “Organizations haven’t been able to tackle incremental deprecation of SOAP web services over time without great difficulty.” Gloo Edge Enterprise 1.8, with the addition of
The evolution of cloud storage as we know it is a fascinating journey filled with projects that built on one another to bring us to where we are today. Interestingly enough, most of the technology used to build a decentralized cloud storage network today has been available for decades. The fact that decentralized cloud storage is viable is mostly because of the growth of storage capacity available at the edge and the incredible increases we’ve made across the globe in bandwidth. Here are four key advancements throughout the years that have paved the way for decentralized cloud storage. Advancement #1: Network Bandwidth Increased JT Olio JT is the CTO at Storj. He oversees product development and led the re-architecture of Storj’s distributed cloud storage platform.

Calico, from network software provider Tigera, is a third-party plugin for Kubernetes geared to make full network connectivity more flexible and easier. Out of the box, Kubernetes provides the NetworkPolicy API for managing network policies within the cluster. The problem many Kubernetes admins find (especially those new to the technology) is that network can quickly become a rather complicated mess of YAML configurations, where you must configure traffic ingress and egress properly, or communication between Kubernetes objects (such as pods and containers) can be difficult. That’s where the likes of Flannel, which cannot configure network policies. With Calico, you can significantly enhance the Kubernetes networking configuration. Take, for instance, the feature limitations found in the default NetworkPolicy, which are: Policies are limited to a single environment and are applied only to pods marked with labels. You can only apply rules to pods, environments, or subnets. Rules can only contain protocols, numerical ports, or named ports. When you add the Calico plugin, the Continue reading
Network software provider Linkerd service mesh, has launched the public beta of William Morgan emphasizes that operational simplicity has always been a focus, he says that they expect Buoyant Cloud to take that one step further. “We want to take the operational burden off of the shoulders of whoever is bringing Linkerd into their organization. We want to handle that for you,” he said. “We want to carry the pager for you, we want to make it so that running Linkerd in production is a trivial task. This falls right in line with everything we’ve been doing with Linkerd since the very beginning — our focus has been really heavily on operational simplicity and on making it so that when you operate Linkerd, you’re not in this horrendous situation where you need to hire a team of experts just to maintain your service mesh. With Buoyant Cloud, we have the opportunity to take on a lot of those operational tasks for you, and make it so you get all Continue reading
Reza Ramezanpour Reza is a developer advocate at Tigera, working to promote adoption of Project Calico. Before joining Tigera, Reza worked as a systems engineer and network administrator. Public cloud infrastructures and microservices are pushing the limits of resources and service delivery beyond what was imaginable until very recently. To keep up with the demand, network infrastructures and network technologies had to evolve as well. Software-defined networking (SDN) is the pinnacle of advancement in cloud networking. By using SDN, developers can deliver an optimized, flexible networking experience that can adapt to the growing demands of their clients. This article will discuss how Tigera’s new Project Calico is an open source networking and security solution. Although it focuses on securing Kubernetes networking, Calico can also be used with OpenStack and other workloads. Calico uses a modular data plane that allows a flexible approach to networking, providing a solution for both current and future networking needs. VPP Continue reading
Well, wasn’t that fun? On June 8, 2021, many internet users went to their usual sites such as Amazon, Reddit, CNN, or the New York Times and found nothing but an “Error 503 service unavailable” and an ominous “connection failure” note. So, what happened? The Commercial Internet Exchange (CIX) other features became important. In particular, everyone started demanding faster performance and lower latency. The solution? CDNs. These companies, which besides Fastly include market-leader Cloudflare, all use the same basic techniques to speed up the net. They take the data from popular sites and place it in distributed caches in points of presence (PoP) close to consumers. If that sounds familiar to you even if you’re a cloud native developer and not a network administrator there’s a good reason. CDNs were one of the first business models Continue reading
Enterprise virtualization software giant VMware says it is “redefining” security as it seeks to help customers meet the challenges associated with a skyrocketing number of threats, more numerous attack vectors, and having fewer human resources at their disposal to help keep attacks at bay. “So what we’re asking all of these IT security teams to do is essentially to do more — and there’s a lot more complexity,” 2020 Threat Landscape report results, 81% of the survey respondents reported a breach during the past 12 months — with four out of the five breaches (82%) deemed material.

Reza Ramezanpour Reza is a developer advocate at Tigera, working to promote adoption of Project Calico. Before joining Tigera, Reza worked as a systems engineer and network administrator. It has been a while since I have been excited to write about encrypted tunnels. It might be the sheer pain of troubleshooting old technologies or countless hours of falling down the rabbit hole of a project’s source code that always motivated me to pursue a better alternative — without much luck. However, I believe luck is finally on my side. In this blog post, we will explore using open source Tigera announced a tech preview of its TLS were available to encrypt workloads’ traffic at higher TCP/IP layers, in this case, the application layer. However, WireGuard targets traffic at a lower layer, the transport layer, which makes it effective for a wider range Continue reading
Bruce Davie Bruce is a computer scientist noted for his contributions to the field of networking. With Larry Peterson, he recently co-founded Systems Approach, LLC, to produce open source books and educational materials. He is a former VP and CTO for the Asia-Pacific region at VMware. Prior to that, he was a Fellow at Cisco Systems, leading a team of architects responsible for multiprotocol label switching (MPLS). Davie has over 30 years of networking industry experience and has co-authored 17 Requests for Comments (RFCs). He was recognized as an Association for Computing Machinery (ACM) Fellow in 2009 and chaired ACM SIGCOMM from 2009 to 2013. Wireless networking is one of those technologies that is, for most of us, so ubiquitous that we take it for granted. WiFi permeates our homes, offices and coffee shops, while cellular networks allow us to stay connected in many other settings. Of course, network access of any sort is a lot less ubiquitous once you get out of densely populated areas. It turns out that making networking ubiquitous requires some fresh thinking about how wireless networks are built. This fresh approach has been realized in an open source project called

With the newest edition of the gRPC protocol, Microservices-based systems will no longer need separate stand-alone service mesh sidecars, noted Envoy, one of the most popular sidecar proxies in use today. Created at Google and released in 2016,
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

At some point, you’ve got to stop building something you think people need and start putting it out there to test in the market. You have to go get users. This is where the first engineers of the Istio service mesh at Google found themselves about four years ago. But, like many things in the still-emerging cloud native space, the first response was: Well, what is it? Who else is using it? Tetrate Service Bridge to act as an application connectivity platform or a technical bridge to take you from those legacies to those modern environments, and to increase reliability and availability. Also called TSB, it looks to solve the issue of networking for heterogeneous workloads. Tetrate Service Bridge, built on Istio and now in general availability, presents itself as the solution to enterprise-grade challenges that can’t be just abstracted out with a Kubernetes layer. The Tetrate team has built out the core set of functionality around controlling traffic across an entire fleet of services, from the edge to the mesh. Butcher says TSB bridges the gap between having service mesh capabilities and actually realizing those capabilities in a way that is safe. He said, “This service mesh is great, but how do I actually use it in my enterprise? How do I change my process to take advantage of the mesh? And actually changing processes is really expensive, so how do I not change my process either?” And those enterprise processes aren’t simple either. They look to use service mesh to enforce security and compliance requirements. Or to gain control and visibility across entire complex infrastructures. How to put security controls in place across highly heterogeneous environments. “Service mesh serves a lot of problems I have but you are telling me I can only have it in Kubernetes? I want those things to help me get from my legacy to a modern environment, not already in that,” Butcher said. TSB helps you manage across the full breadth of compute, connecting Kubernetes and legacy infrastructure. He gives examples you can use to link with Istio and Envoy and just start assembling your application network. “Tetrate Service Bridge is a platform for applications to communicate securely and successfully without having to get into the weeds of what lives there.”— Zack Butcher, Founding Engineer, Tetrate Butcher says then there’s the enterprise management side, teams need to be able to prove they are using service mesh correctly and securely. He says TSB enables teams to divvy up their physical infrastructure and cloud-based environments, with multitenancy and controls, so you can use service mesh to “do cool things at runtime.” The connectivity tool works not only with Istio and the Apache Skywalking, enabling observability across whole systems. They are clear that while they are a tool to ease the use of these open source tools and the whole Tetrate team is contributors to the open source projects they depend on, they are not an open core company, intentionally. “In my opinion, there’s this really big tension in open-core companies. If me, as a developer, I have to decide project or product that people pay for — he doesn’t want to make the value prop decision,” Butcher explained. He continued, “We are building a layer on top of the open source pieces. We are assembling these open source pieces together in a coherent system.” Another part of this decision is that, since they are still essentially using open source tools, enterprises can do so in a relatively cheap way through Tetrate. Butcher points to the fundamental difference between enterprise closed source products like TCB and the open source projects it serves. “Capabilities go in open source and then how you manage those capabilities and how you use them within an organization, that’s what you put in the product,” he said.” While they only went fully public with TSB in April, they built it alongside adopters from the start. Butcher, paraphrasing Socrates, said that after the “pain of adopting Istio — we were in a cave without users” they were determined to build hand in hand with users. One such early adopter was FICO, the organization that creates the predominant credit risk score in the U.S. One emerging use case for service mesh is encryption in transit to ensure compliance to ever-changing regulations and standards from HIPAA and GDPR to automate enforcement of
