Continuing Integration and Continuing Development (CI/CD), and containers are both at the heart of modern software development. CI/CD developers regularly break up applications into microservices, each running in their own container. Individual microservices can be updated independently of one another, and CI/CD developers aim to make those updates frequently.
This approach to application development has serious implications for networking.
There are a lot of things to consider when talking about the networking implications of CI/CD, containers, microservices and other modern approaches to application development. For starters, containers offer more density than virtual machines (VMs); you can stuff more containers into a given server than is possible with VMs.
Meanwhile, containers have networking requirements just like VMs do, meaning more workloads per server. This means more networking resources are required per server. More MAC addresses, IPs, DNS entries, load balancers, monitoring, intrusion detection, and so forth. Network plumbing hasn’t changed, so more workloads means more plumbing to instantiate and keep track of.
Containers can live inside a VM or on a physical server. This means that they may have different types of networking requirements than traditional VMs, (only talking to other containers within the same VM, for example) than other workloads. Continue reading

Mirantis scored an eight-figure, multi-year deal to provide the carrier with core infrastructure software that has Kubernetes running on bare metal on-premises.
The president’s commitment comes as his top cybersecurity chief warns that China could use Huawei’s 5G networking equipment to steal “trillions” of dollars of intellectual property.
Ciena anticipates that the Blue Planet Division will reach $50 to $60 million in annual revenue during fiscal 2019, growing to $100 to $120 million in 2021.
The new product, based on the open source Eclipse Che integrated development environment project, enables OpenShift developers to conduct entire projects in Kubernetes..
At the end of the day, most engineers want to implement IPv6 because they know, deep down, that it is an eventual necessity. One problem is that no one is talking about quitting IPv4. If you add IPv6 to your network, you increase costs, complexity and operations. IPv4 is going to be around for 25 […]

Cloudflare Access secures your internal sites by adding authentication. When a request is made to a site behind Access, Cloudflare asks the visitor to login with your identity provider. With service tokens, you can now extend that same level of access control by giving credentials to automated tools, scripts, and bots.
When users attempt to reach a site behind Access, Cloudflare looks for a JSON Web Token (a JWT) to determine if that visitor is allowed to reach that URL. If user does not have a JWT, we redirect them to the identity provider configured for your account. When they login successfully, we generate the JWT.
When you create an Access service token, Cloudflare generates a unique Client ID and Secret scoped to that service. When your bot sends a request with those credentials as headers, we validate them ourselves instead of redirecting to your identity provider. Access creates a JWT for that service and the bot can use that to reach your application.
Within the Access tab of the Cloudflare dashboard, you’ll find a new section: Service Tokens. To get started, select “Generate a New Service Token.”
You’ll be asked to Continue reading
Last year, we published “The Dawn of New Digital Rights for Finnish Citizens,” about the launch of the New Digital Rights MOOC, a collaboration between Open Knowledge Finland and the Internet Society’s Finland Chapter. Raoul Plommer wrote, “The aim of the project is to make citizens more aware of their digital rights, initially focusing on explaining GDPR (General Data Protection Regulation) and MyData…through a MOOC platform and series of workshops that create content and train people and organizations to use it.” Plommer has written an update on the project:
We have come a long way from the beginning of last year, when we were given funding for the project from Internet Society’s Beyond the Net Funding Programme, and Eurooppatiedotus, which is a sub-organization of the Finnish Foreign Ministry.
It took us several months to agree on what is essential to know about the General Data Protection Regulation (GDPR) and how we would present it to the general public. It was also challenging to get all the content done without actually paying everyone for all their hard work. Both of our funders had a strict limit on how much money could be spent on salaries (15% and 30%). On Continue reading
Red Hat and Affirmed Networks helped with the deployment. Turkcell is on track to have 40 percent of its voice and data services capacity virtualized by year-end.
