Exploring VMware’s Kubernetes App Connectivity and Security Solution: A Deep Dive, with Demos

Modern apps need to run in multi-cluster, multi-cloud environments across a mix of traditional and microservices architectures. In this context, enterprise platform, infrastructure, and operations teams are presented with unique challenges in securely connecting and managing modern workloads, in delivering scalable services, or bridging between traditional VM workloads and containers, and supporting production operations for modern apps.  

VMware recently introduced the “VMware Modern Apps Connectivity solution”, which brings together the advanced capabilities of Tanzu Service Mesh (TSM) and VMware NSX Advanced Load Balancer ALB (formerly Avi Networks) address today’s unique enterprise challenges.  

In this blog, we’ll take a deeper look at this solution and demonstrate how its cloud-native principles enable a set of important use cases that automate the process of connecting, observing, scaling, and better securing applications across multi-site environments and clouds. We’ll also show how state-of-the-art capabilities in this solution — like Global Server Load Balancing (GSLB) and Intelligent Autoscaling — enable enterprises to deliver advanced use cases such as cloud-bursting.  

Step 0: Set up (typical HA architecture for a modern distributed app) 

Let’s start by looking at our set-up, which is a typical architecture for a highly-available modern app deployment Continue reading

Volume Management, Compose v2, Skipping Updates, and more in Docker Desktop 3.4

We are excited to announce the release of Docker Desktop 3.4.

This release includes several improvements to Docker Desktop, including our new Volume Management interface, the Compose v2 roll-out, and changes to how to Skip an update to Docker Desktop based on your feedback.

Volume Management

Have you wanted a way to more easily manage and explore your volumes?

In this release we’re introducing a new capability in Docker Desktop that helps you to create and delete volumes from Desktop’s Dashboard as well as to see which ones are In Use.

For developers with Pro and Team Docker subscriptions, we’ll be bringing a richer experience to managing your volumes. 

You’ll be able to explore the contents of the volumes so that you can more easily get an understanding of what’s taking up space within the volume.

You’ll also be able to easily see which specific containers are using any particular volume.

We’re also looking to add additional capabilities in the future, such as being able to easily download files from the volume, read-only view for text files, and more. We’d love to hear more about what you’d like to see us prioritize and focus on in improving the Continue reading

New NVMe spec brings new support for hard drives

The new NVM Express 2.0 has been released and with it a surprise: The non-volatile memory express protocol—best known for handling SSD speeds—is now offering full-blown support for traditional hard-disk drives.This is quite unexpected because SSDs are orders of magnitude faster than traditional HDDs. [ Read also: How to plan a software-defined data-center network ] The first flash-based SSDs used SATA/SAS physical interfaces borrowed from existing hard drive-based enterprise server/ storage systems. However, none of these interfaces and protocols were designed for high-speed storage media and the SATA/SAS bus became a bottleneck for the much faster SSD.To read this article in full, please click here

Celebrating 7 Years of Project Galileo

Every June, we celebrate the anniversary of Project Galileo. This year, we are proud to celebrate seven years of protecting the most vulnerable groups on the Internet from cyber attacks. June is a busy month for us at Cloudflare, with the anniversary of Project Galileo and Access Now’s RightsCon, one of the largest events on human rights in the digital age. As we collaborate with civil society on topics from technology, privacy, digital security and public policy, we learn how to better protect critical voices on the Internet but also how to use the Cloudflare network to make positive changes to the Internet ecosystem.

We started Project Galileo in 2014 with the idea that we need to protect voices that are targeted for working in sensitive areas. As such, we give these voices the resources to protect themselves online against powerful opponents. Whether their opponent’s aim is to intimidate, silence, or steal sensitive information, cyber attacks can cause significant damage to organizations that work in areas such as human rights, independent media, education, and social justice. As the world moves online — a factor accelerated by COVID-19 — access to powerful cybersecurity tools is critical for organizations around the world. Continue reading

Real-Life Network-as-a-Graph Examples

After reading the Everything Is a Graph blog post, Vadim Semenov sent me a long list of real-life examples (slightly edited):

---

I work in a big enterprise and in order to understand a real packet path across multiple offices via routers and firewalls (when mtr or traceroute don’t work – they do not show firewalls), I made OSPF network visualization based on LSDB output. The idea is quite simple – save information about LSA1 and LSA2 (LSA5 optionally) and that will be enough in order to build a graph (use show ip ospf database router/network on Cisco devices).

Why the cloud will never eat the data center

Sometimes it’s hard to see gradual changes in technology paradigms because they’re gradual.  Sometimes it helps to play “Just suppose…” and see where it leads. So, just suppose that the cloud did what some radical thinkers say, and “absorbed the network”. That’s sure an exciting tag line, but is this even possible, and how might it come about?Companies are already committed to a virtual form of networking for their WAN services, based on VPNs or SD-WAN, rather than building their own WANs from pipes and routers.  That was a big step, so what could be happening to make WANs even more virtual, to the point where the cloud could subsume them?  It would have to be a data-center change.To read this article in full, please click here

Technology Advancements that Led to the Success of NASA’s Mars Rover Landing

Space exploration is one of the most unique and innovative things in the world. With each passing mission NASA employs new and advanced technology in their space missions. Space missions aren’t always a success however with latest technology, NASA has been enjoying some great success.

Ingenuity Mars Helicopter

Mars has a very thin atmosphere so it was necessary for NASA to come up with a powerful object that could fly around the planet and take photographs. This ingenuity Mars helicopter can easily fly around the red planet so that the astronauts can take pictures even far away from their landing base.

MOXIE

MOXIE is one of the most important technologies that is going to revolutionize the space program. MOXIE is a technology that is going to convert the carbon dioxide in Mars atmosphere to oxygen. This will be a great way to have unlimited amount of oxygen once NASA plans to start a base on Mars.

In addition to the above two technologies, NASA also uses new technologies for entry in to the atmosphere. descent and then landing.

Range Trigger

Good landing is very important when you are trying to land on another planet. You need to hit all the Continue reading

Introducing OSPF Support in NSX-T 3.1.1

NSX-T has revolutionized the data center and plays a key role in modern data center fabrics. Its unmatched capabilities are key elements in any effort to modernize networking in the data center.

NSX-T version 3.1.1 will go down as a critical milestone in this journey, as it supports OSPF version 2.

Based on RFC 2328, Open Shortest Path First Version 2 (OSPF v2) provides fast convergence, scalability, and is widely known among network architects and their operations teams. As a result, it is one of the most popular link state routing protocols in enterprise networks and data centers.

Interconnecting your physical networking fabric with NSX-T was possible using static routes and BGP. OSPF is now an option to consider leveraging dynamic routing protocols in the data center. By supporting OSPF as a dynamic routing protocol, existing NSX for vSphere customers can migrate seamlessly to NSX-T.

In this blogpost, we will demonstrate how to implement OSPFv2 within NSX-T in your data center.

OSPF Support in NSX-T

Providing connectivity between users and applications in a data center is crucial. The main purpose of any routing protocol is to dynamically exchange or share information regarding the reachability of a network.
