Real-Time Data Access Across Highly Distributed Environments

The goal is straightforward, but getting there has proven to be a challenge: how to offer real- or near real-time access to data that is continually refreshed on an as-needed basis across a number of different distributed environments. Consequently, as different systems of data and their locations can proliferate across different network environments — including multiclouds and on-premises and, in many cases, geographic zones — organizations can struggle to maintain low-latency connections to the data their applications require. The challenges are especially manifest when users require and increasingly demand that their experiences, which are often transactional-based, are met in near- or real-time that require data-intensive backend support. Many organizations continue to struggle with the challenges of maintaining and relying on data streaming and other ways, such as through so-called “speed layers” with cached memory, to maintain low-latency connections between multicloud and on-premises environments. In this article, we describe the different components necessary to maintain asynchronously updated data sources consisting of different systems of record for which real-time access is essential for the end-user experience. For the CIO, the challenges consist of the ability for applications to have low-latency access to data, often dispersed across a number of often highly distributed Continue reading

CNCF Projects Bring Service Mesh Interoperability, Benchmarks

Both the Service Mesh Performance (SMP) projects joined the Cloud Native Computing Foundation (CNCF) earlier this month at the Sandbox level. Meshery is a multiservice mesh management plane offering lifecycle, configuration, and performance management of service meshes and their workloads, while SMP is a standard for capturing and characterizing the details of infrastructure capacity, service mesh configuration, and workload metadata. When the projects first applied in April for inclusion, the Technical Oversight Committee (TOC) had one clarifying question for them: should they be combined with or aligned in some manner with the Lee Calcote, founder of verifies that, in fact, it is a certain kind of a service mesh,” said Calcote. “So all in one Continue reading

Infoblox: How DDI Can Help Solve Network Security and Management Ills 

Network connections can be likened to attending an amusement park, where Dynamic Host Configuration Protocol (DHCP), serves as the ticket to enter the park and the domain name system (DNS) is the map around the park. Network management and security provider Infoblox made a name for itself by collapsing those two core pieces into a single platform for enterprises to be able to control where IP addresses are assigned and how they manage network creation and movement. “They control their own DNS so that they can have better control over their traffic,” explained Infoblox: How DDI Can Help Solve Network Security and Management Ills  Also available on Google Podcasts, PlayerFM, Spotify, TuneIn Infoblox’s name for this unified service is DDI, which is

Video Game Security Should Be Simple for Developers

Video games continue to Bharat Bhat (Okta marketing lead for developer relations) cover why and how video game platforms and connections should be more secure, with guest Okta senior developer advocate Video Game Security Should Be Simple for Developers Also available on Google Podcasts, PlayerFM, Spotify, TuneIn The gaming industry has often served as a showcase for some of the industry’s greatest programming talents. As a case in point, Adds Legacy SOAP Integration for Gloo Edge 1.8 Release

Service mesh integration software provider 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

4 Advancements That Led to Decentralized Cloud Storage

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. He was previously director of engineering at Space Monkey, which was acquired by Vivint in 2014.

Install Calico to Enhance Kubernetes’ Built-in Networking Capability

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

Buoyant Cloud Beta Brings Simplified Linkerd

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

Lightning-Fast Kubernetes Networking with Calico and VPP

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.

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

What the Heck Happened to the Internet? Fastly’s Hard Fall and Quick Recovery

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

VMware Redefines Security After a Surge in Attacks

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. At the Continue reading

Calico Integration with WireGuard Using kOps

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

Magma Brings a Systems Approach to Wireless Networking

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
