Docker Compose: From Local to Amazon ECS
By using cloud platforms, we can take advantage of different resource configurations and compute capacities. However, deploying containerized applications on cloud platforms is proving to be quite challenging, especially for new users who have no expertise on how to use that platform. As each platform may provide specific APIs, orchestrating the deployment of a containerized application can become a hassle.
Docker Compose is a very popular tool used to manage containerized applications deployed on Docker hosts. Its popularity is maybe due to the simplicity on how to define an application and its components in a Compose file and the compact commands to manage its deployment.
Since cloud platforms for containers have emerged, being able to deploy a Compose application on them is a most-wanted feature by many developers that use Docker Compose for their local development.
In this blog post, we discuss how to use Docker Compose to deploy containerized applications to Amazon ECS. We aim to show how the transition from deploying to a local Docker environment to deploying to Amazon ECS is effortless, the application being managed in the same way for both environments.

In order to exercise the examples in this blogpost, the following tools need Continue reading
Cisco SD-WAN: vManage, vBond, and vMSmart On-Prem Installation Process.
Introduction
This section explains the process how to build an on-prem Cisco Viptela based SD-WAN control plane system. It starts by setting up an enterprise Certificate Server using the Cisco CSR1000V cloud router. Next, it goes through the process of root certificate generation. The rest of the chapter explains the initial configuration and certification installation processes from vManage, vBond, and vSmart viewpoints.

Complexity Bites Back
What percentage of business-impacting application outages are caused by networks? According to a recent survey by the Uptime Institute, about 30% of the 300 operators they surveyed, 29% have experienced network related outages in the last three years—the highest percentage of causes for IT failures across the period.
A secondary question on the survey attempted to “dig a little deeper” to understand the reasons for network failure; the chart below shows the result.
We can be almost certain the third-party failures, if the providers were queried, would break down along the same lines. Is there a pattern among the reasons for failure?
Configuration change—while this could be somewhat managed through automation, these kinds of failures are more generally the result of complexity. Firmware and software failures? The more complex the pieces of software, the more likely it is to have mission-impacting errors of some kind—so again, complexity related. Corrupted policies and routing tables are also complexity related. The only item among the top preventable causes that does not seem, at first, to relate directly to complexity is network overload and/or congestion problems. Many of these cases, however, might also be complexity related.
The Uptime Institute draws this same lesson, though Continue reading

Roundtable: Key IT Lessons Learned from 30 Years of the Evolving Enterprise WAN
I’ll be joining Jeff Tantsura, Nick Buraglio, and Brooks Westbrook for a roundtable on March 16, 9 am PST (that’s tomorrow if you’re reading this the day it publishes) about the development of wide area networking technologies up until today. This is the first part of a two part series on changes in the wide area network.
The Third Time Charm Of AMD’s Milan Epyc Processors
With every passing year, as AMD first talked about its plans to re-enter the server processor arena and give Intel some real, much needed, and very direct competition and then delivered again and again on its processor roadmap, it has gotten easier and easier to justify spending at least some of the server CPU budget with Intel’s archrival in the X86 computing arena. …

The Week in Internet News: Berners-Lee Warns of Growing Digital Divide
A big divide: Tim Berners-Lee, inventor of the World Wide Web, says the digital divide has grown during the COVID-19 pandemic, the BBC reports. He called on governments to provide universal broadband by 2030 in his annual letter marking the anniversary of the Web. About one-third of young people do not have Internet access and many more people lack connections that are good enough to allow them to work or learn from home.
Spy vs. spy: Hackers have breached surveillance camera data collected by Silicon Valley startup Verkada and gained access to live feeds of 150,000 security cameras inside hospitals, companies, police departments, prisons, and schools, Bloomberg reports. Live cameras inside Tesla factories, women’s health clinics, and psychiatric hospitals were also breached. The breach exposed the reach of surveillance, the Washington Post suggested, with one expert saying that “our desire for some fake sense of security is its own security threat.”

Enhancing privacy-focused Web Analytics to better meet your metrics needs
Last December we opened up our brand new privacy-first Web Analytics platform to everyone. Today, we’re excited to announce the release of three of the most requested features: adding multiple websites to an account, supporting Single-page Applications (SPA) as well as showing Core Web Vitals in Web Analytics.
Bringing privacy-first analytics to everyone
Since we launched two months ago, we’ve received a lot of feedback from our users. We are really happy that we are able to provide our privacy-first analytics to so many of you.
Popular analytics vendors have business models driven by ad revenue. Using them implies a bargain: they track visitor behavior and create buyer profiles to retarget your visitors with ads; in exchange, you get free analytics.
Our mission is to help build a better Internet, and part of that is to deliver essential web analytics to everyone with a website without compromising user privacy. We’ve never been interested in tracking users or selling advertising. We don’t want to know what you do on the Internet — it’s not our business.
You now can measure multiple sites
When we launched Web Analytics, each account was only able to measure one website. We are happy to announce Continue reading
