IBM, Bharti Airtel partner on edge cloud offerings in India

IBM will work with telecom provider Bharti Airtel to offer edge cloud services to organizations in India, providing a new option for companies looking to leverage edge services and keep their data in-country.The partnership, announced Wednesday, will extend across 20 of India’s largest cities, with a grand total of 120 network data centers included in the system. The idea is to offer business customers the ability to use cutting-edge new capabilities—for example, automated inspection for manufacturing, or high-level analytics for healthcare providers—without using global cloud services that might take data out of the country or having to implement that type of system completely in-house.To read this article in full, please click here

Hedge 147: The SRE with Niall Murphy (part 1)

It seems like only yesterday we started talking about the Site Reliability Engineer, and their place in the IT ecosystem. Over the last several years, the role of the SRE has changed—and it’s bound to continue changing. On this episode of the Hedge, Niall Murphy joins Tom Ammon and Russ White to discuss the changing role of the SRE, and what the SRE could be.

Day Two Cloud 163: Is The Tech Market Too Focused On Developers?

Today on the Day Two Cloud podcast we have a frank discussion about tech marketing. Why? Because engineers are a target of marketing, so it's helpful to know how marketing works, what's trying to be communicated, and how it could be better. We also discuss whether the tech industry has over-committed on chasing developers while ignoring operations and sysadmins, why ops and sysadmins shouldn't be ignored, and more. Our guest is Gina Rosenthal, founder of Digital Sunshine Solutions.

How to work on Linux with filenames that contain blanks

Personally, I always try to avoid filenames with blanks, usually by filling those places where less blank-phobic people would use them with underscores or hyphens. The filenames are still easy to decipher, and I don’t have to trouble myself with enclosing them in quotes when I want to use them. As a result, some of my files look like this:locking-accts Lost_World I also rarely add .txt file extensions to the end of text files unless I plan to share them with my Windows system.Use quotes When blanks in file names are preferable for any reason, however, there are several easy ways to work with them. To reference existing files, you can enclose the filenames in single or double quotes. In fact, you can make this easier by starting with a quote mark, typing as much of the filename as needed to differentiate it from other files and then pressing the tab key to initiate filename completion. For example, typing the portion of a filename as shown in the example below and then pressing tab should add the rest of the filename to the “file n” beginning:To read this article in full, please click here

How we built Pingora, the proxy that connects Cloudflare to the Internet

Introduction

Today we are excited to talk about Pingora, a new HTTP proxy we’ve built in-house using Rust that serves over 1 trillion requests a day, boosts our performance, and enables many new features for Cloudflare customers, all while requiring only a third of the CPU and memory resources of our previous proxy infrastructure.

As Cloudflare has scaled we’ve outgrown NGINX. It was great for many years, but over time its limitations at our scale meant building something new made sense. We could no longer get the performance we needed nor did NGINX have the features we needed for our very complex environment.

Many Cloudflare customers and users use the Cloudflare global network as a proxy between HTTP clients (such as web browsers, apps, IoT devices and more) and servers. In the past, we’ve talked a lot about how browsers and other user agents connect to our network, and we’ve developed a lot of technology and implemented new protocols (see QUIC and optimizations for http2) to make this leg of the connection more efficient.

Today, we’re focusing on a different part of the equation: the service that proxies traffic between our network and servers on the Internet. This proxy Continue reading

VLAN Interfaces and Subinterfaces

Early bridges implemented a single bridging domain across all ports. Within a few years, we got multiple bridging domains within a single device (including bridging implementation in Cisco IOS). The capability to have multiple bridging domains stretched across several devices was still missing… until the modern-day Pandora opened the VLAN box and forever swamped us in the complexities of large-scale bridging.

Software-defined perimeter: What it is and how it works

A growing number of organizations are drawing an invisible line around their internet-connected resources in an effort to keep attackers at bay. Called software-defined perimeter (SDP), it is based on the relatively simple idea of throwing a virtual barrier around servers, routers, printers, and other enterprise network components.The goal of SDP is to protect networks behind a flexible, software-based perimeter. "Advantages include stronger security and greater flexibility and consistency," says Ron Howell, principal SD-WAN and SASE architect at IT and business consulting firm Capgemini Americas.To read this article in full, please click here

What’s new in Calico Cloud: General availability of new container security features

Summer is almost over but we are bringing the heat back with the official release of Tigera’s new container security features. With this official launch, Calico leads the industry by offering a complete line of solutions across every stage of a cloud-native application CI/CD pipeline. From a new and improved approach to scanning container images for vulnerabilities to strengthening runtime security with improved performance, we’ve significantly improved and enhanced our Image Assurance and Runtime Threat Defense features for this exciting new phase of our Calico Cloud offering. Let’s take a look at the new container security features of this release.

Vulnerability management through Image Assurance

Scanning container images for vulnerabilities is a critical first step in stopping malicious software from being deployed. As business demands grow, development teams are pushed to churn out updates and new features faster. As a result, DevOps teams require assistance to help them quickly identify vulnerabilities in the registries where the container images are pulled from. Calico Cloud is now offering a CLI-based scanner for on-demand scanning, where customers can locally scan for vulnerabilities in their build stage. A lightweight downloadable binary is all it takes to perform these scans and integrate the process into Continue reading

VMware to pay $8M fine, settling charges it fudged the timing of backlogged orders

At a time when vendor order backlogs are at an all-time high and scrutiny of them is as well, VMware has agreed to pay an $8 million fine for disingenuous backlog reporting practices in 2019 and 2020.The Securities and Exchange Commission had charged VMware for misleading investors about its order backlog management practices, specifically stating that VMware had  moved revenue into future quarters by delaying product deliveries to customers, concealing the company’s slowing performance relative to its projections, the SEC stated.
