VMware Tanzu Service Mesh Named a Leader in GigaOm Radar Report on Service Mesh

GigaOm placed VMware Tanzu Service Mesh (TSM) in the leader ring of its 2021 GigaOm Radar Report for Evaluating Service Mesh, cementing VMware’s status as the open-source choice for connecting and securing modern applications across single and multi-cloud environments.

As enterprises continue to split applications into microservices that can be spun up or down as needed, service meshes give DevOps the ability to seamlessly and simply orchestrate connectivity and security services across multi-cloud environments, automatically and at scale. This common abstraction layer for application services enables true app resiliency, observability, and security across single and multi-cloud environments — a critical superpower for organizations focused on delivering powerful and consistent experiences.

VMware continues to lead

Citing Tanzu Service Mesh’s open-source architecture, dominance in the enterprise market, innovative road map, and focus on improving security, the authors of the report feel that Tanzu Service Mesh gives enterprises the best chance of gaining that all-important visibility and control with modern applications.

The key to this, of course, is Tanzu Service Mesh’s ability to seamlessly abstract the application layer from the infrastructure layer through Global Namespace (GNS). By onboarding applications to a Global Namespace, developers, operations, and security gain consistent policy controls and operational Continue reading

Sudan woke up without Internet

Sudan woke up without Internet
Sudan woke up without Internet

Today, October 25, following political turmoil, Sudan woke up without Internet access.

In our June blog, we talked about Sudan when the country decided to shut down the Internet to prevent cheating in exams.

Now, the disruption seems to be for other reasons. AP is reporting that "military forces ... detained at least five senior Sudanese government figures.". This afternoon (UTC) several media outlets confirmed that Sudan's military dissolved the transitional government in a coup that shut down mobile phone networks and Internet access.

Cloudflare Radar allows anyone to track Internet traffic patterns around the world. The dedicated page for Sudan clearly shows that this Monday, when the country was waking up, the Internet traffic went down and continued that trend through the afternoon (16:00 local time, 14:00 UTC).

Sudan woke up without Internet

We dug in a little more on the HTTP traffic data. It usually starts increasing after 06:00 local time (04:00 UTC). But this Monday morning, traffic was flat, and the trend continued in the afternoon (there were no signs of the Internet coming back at 18:00 local time).

Sudan woke up without Internet

When comparing today with the last seven days' pattern, we see that today's drop is abrupt and unusual.

Network Break 356: Aruba Beefs Up ToR Switch With DPUs; VMware Stands Free

This week on the Network Break podcast we discuss a new ToR switch from Aruba that includes built-in silicon to offload security and network services. Dell Technologies says the VMware spin-off will be complete by November 1st, and SASE startup Cato Networks raises $250 in an F round of funding.

How eBPF Streamlines the Service Mesh

There are several service mesh products and projects today, promising simplified connectivity between application microservices, while at the same time offering additional capabilities like secured connections, observability, and traffic management. But as we’ve seen repeatedly over the last few years, the excitement about service mesh has been tempered by practical additional overhead. Let’s explore how Envoy or wrote about his experiences configuring Istio to reduce consumption from around 1GB per proxy (!) to a much more reasonable 60-70MB each. But even in our Continue reading

Cloudflare Tunnel for Content Teams

Cloudflare Tunnel for Content Teams
Cloudflare Tunnel for Content Teams

A big part of the job of a technical writer is getting feedback on the content you produce. Writing and maintaining product documentation is a deeply collaborative and cyclical effort — through constant conversation with product managers and engineers, technical writers ensure the content is clear and serves the user in the most effective way. Collaboration with other technical writers is also important to keep the documentation consistent with Cloudflare’s content strategy.

So whether we’re documenting a new feature or overhauling a big portion of existing documentation, sharing our writing with stakeholders before it’s published is quite literally half the work.

In my experience as a technical writer, the feedback I’ve received has been exponentially more impactful when stakeholders could see my changes in context. This is especially true for bigger and more strategic changes. Imagine I’m changing the structure of an entire section of a product’s documentation, or shuffling the order of pages in the navigation bar. It’s hard to guess the impact of those changes just by looking at the markdown files.

We writers check those changes in context by building a development server on our local machines. But sharing what we see locally with our stakeholders has Continue reading

Infrastructure 3. Deploying High Performance Pure Virtual Linux Router – 6WIND

Hello my friend,

Network Function Virtualisation (NFV) is not a new topic. There are numerous blogpost and articles, even in our blog, which review this topic. Yet, there is much more we can cover. Today we’ll share some insights on one of the very interesting products existing on the market today: 6WIND vRouter Turbo Router. We have a limited amount of days to write a few articles under our evaluation license. Hence, we’ll focus only on the most critical elements.

Is Linux Suitable for Automation?

It absolutely is. In fact, Linux is the real home for automation systems, as in many cases it hosts the tools you create in Ansible, Python, Bash, Go or any other language. At the same time, in order to effectively work with Linux, you need to know how to automate management and operation of Linux operating system itself. And you will be absolutely capable to do that, once you attend our Continue reading

Mark Zuckerberg, unlike Einstein, did not dream up Facebook out of a sense of moral duty, or a zeal for world peace. This summer, the population of Zuckerberg’s supranational regime reached 2.9 billion monthly active users, more humans than live in the world’s two most populous nations—China and India—combined.

Given these concerns, it seems especially bizarre that Amazon was willing to reference the price of competing smart thermostats sold via its platform during the launch. Its smart thermostat is “less than half the average cost of a smart thermostat sold on Amazon.com,” the company’s senior vice president of devices and services, Dave Limp, said.

Worth Reading: Network Validation Evolution at Hostinger

Network validation is becoming another overhyped buzzword with many opinionated pundits talking about it and few environments using it in practice (why am I not surprised?)

As always, there are exceptions. They don’t have to be members of the FAANG club, and some of them get the job done with open-source tools regardless of what vendor marketers would like you to believe. For example, Donatas Abraitis described how the Hostinger networking team gradually implemented network validation using Cumulus VX, Vagrant, SuzieQ, PyTest and Test Kitchen. Enjoy!
