In this wiki entry disguised as a RFC 7872, “Observations on the Dropping of Packets with IPv6 Extension Headers in the Real World” highlights IPv6 Extension Headers are effectively unusable since internet providers are dropping IPv6 fragment and failing to support Extension Headers. In IPv6, an extension header is any header that follows the initial 40 […]

A company’s important applications often are subjected to random and capricious changes due to forces well beyond the control of IT or management. Events like a corporate merger or even a top programmer on an extended vacation can have an adverse impact on the performance and reliability of critical company infrastructure.
During the second day keynote at DockerCon 2017 in Austin TX, Lily Guo and Vivek Saraswat showed a simulation of how to use Docker Enterprise Edition and its application transformation tools to respond to random events that threaten to undermine the stability of their company critical service.
The demo begins as two developers are returning to work after an extended vacation. They discover that, during their absence, their CEO has unexpectedly hired an outside contract programmer to rapidly code and introduce an entire application service that they know nothing about. As they try to build the new service, however, Docker Security Scan detects that a deprecated library has been incorporated by the contractor. This library is found to have a security vulnerability which violates the company’s best practice standards. As part of Docker Enterprise Edition Advanced, Docker Security Scan automatically keeps track of code contributions and acts as a Continue reading
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Network analytics is key to helping IT proactively deliver great user experiences, but analytics for the enterprise access network is complicated. Besides the array of connectivity options, the heterogeneous mix of client devices and the different application models to accommodate, there are volumes of relevant input data that can be used, such as:
Nyansa Figure 1. How network data is used today. Is this really analytics?

Today at DockerCon, we announced the Modernize Traditional Applications (MTA) Program to help enterprises make their existing legacy apps more secure, more efficient and portable to hybrid cloud infrastructure. Collaboratively developed and brought to market with partners Avanade, Cisco, HPE, and Microsoft, the MTA Program consists of consulting services, Docker Enterprise Edition, and hybrid cloud infrastructure from partners to modernize existing .NET Windows or Java Linux applications in five days or less. Designed for IT operations teams, the MTA Program modernizes existing legacy applications without modifying source code or re-architecting the application.
The First Step In The Microservices Journey
In working with hundreds of our enterprise IT customers the last couple years, when we sit down with them one of the first questions they inevitably ask is, “What is the first step we should take toward microservices?”
Through experience we have found that, for the vast majority of them, the best answer is, “Start with what you have today – with your existing applications.” Why is this the right place for them to start? Because it recognizes two realities facing enterprise IT organizations today: existing applications consume 80% of IT budgets, and most IT organizations responsible for existing Continue reading
If you’re running a SaaS company, you know how important it is that your application is performant, highly available, and hardened against attack. Your customers—and your revenue stream—depend on it. Putting your app behind a solution such as Cloudflare is an obvious move for your own infrastructure, but how do you securely (and easily) extend these benefits to your customers?
If your customers interact with your app on your domain and don’t care about branding under their custom or “vanity” domain (or aren’t paying you for the ability to do so), the solution is straightforward: onboard your domain to Cloudflare and serve the app at either https://app.yourcompany.ltd or https://yourcustomer.yourcompany.ltd. But if your customers want to host your application, portal, content management solution, etc. on their own domain for improved SEO and discoverability, e.g., https://app.yourcustomer.site the solution is not so easy.
Until today, your best bet was to ask them to CNAME over to your infrastructure, have them generate a private key and CSR, send the latter to a CA for signing, and then securely provide you with the Continue reading
