ISSUE 156: Kubernetes is Ready for IPv6

Talk Talk Talk

“The programming model for serverless is still mainly limited to stateless functions — the so-called Function-as-a-Service (FaaS) model — which limits the range of use-cases supported.”

Lightbend co-founder Jonas Bonér, on expanding the role of serverless to include stateful workloads.

Mismatch between IT and finance overspend perceptions

Spending on public cloud computing continues to increase and with it, interest in ways to control cloud budgets. Two recent studies show that changes in IT responsibility and coordination with other departments often determines how much of a problem “uncontrolled” cloud spending.

IT and finance clearly need to better align their management of cloud costs, according to 451 Research’s “Cost Management in the Cloud Age” (sponsored by Cloudability). While 40 percent of respondents in IT roles say their budgets and forecasts are accurate, only 26 percent of those in finance roles say they rarely go past their cloud budgets. Finance can get a better view of spending if it works closely with IT, but for now, only 28 percent of respondents collaborate across both IT and finance.

Kubernetes Is Ready for IPv6

While many are eager to adopt these distributed systems software, Kubernetes is still experiencing growing pains. Last week, we wrote about how, because it was originally written in Java, K8s is still being refactored out of an architecture that makes it very difficult for multiple developers to collaborate on.

Now Kubernetes is catching up with another technology, IPv6.The Internet Protocol serves as the fundamental addressing format for the Internet. The originators, not predicting IoT or smartphones, didn’t expect that all the IP would ever be used. They designed a 32-bit address field, consisting of four 8-bit octets that could accommodate about 4.3 billion assignable addresses. Most of the IPv4 addresses are taken. Earlier this year, the last IPv4 block was sold. Only 43 million are left out in the wild.

Cisco has estimated that we’ll need 50 billion addresses next year for IoT alone. Needless to say, we have a shortage. IPv6 to the rescue! This format has 128 bit addresses space, offering a total of 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses, or 340 undecillion addresses. So that should last us awhile.

The Internet Engineering Task Force has warned us about Ipv4 exhaustion for decades, though enterprises have been slow to adopt it, if only because that there is no real upside for enterprises themselves to migrate to IPv6. So it was not a controversial move to start K8s out on IPv4 only. But early adopters of IPv6 have been the telecommunications firms, and since they are also looking at Kubernetes for 5G, it is not surprising they are pushing the envelope forward with IPv6, reports Mary Branscombe on The New Stack this week.   

With the 1.9 release, the container orchestrator supports IPv6-only clusters and the latest release, v1.13, uses the IPv6-friendly CoreDNS. The next big challenge is dual stack support for both IPv4 and IPv6. “Dual-stack IPv6 support for Kubernetes is more or less design-complete,” Google’s Tim Hockin said. “We have a very nice Kubernetes Enhancement Proposal for it, but that work has stalled a bit. It will be a few releases before that work is done, best case.”

How to Design Inclusion into a Tech Event

Let’s assume tech companies and tech conferences really are starting to understand that it’s not only right to embrace diversity, but that it benefits the bottom line through increased innovation, among other benefits. So just how do you make your tech conference welcoming and diverse? Make sure you have a few tickets for those who can not afford them. Appoint someone with making sure diversity, inclusion and accessibility are consistently part of each planning step. And develop a Code of Conduct to ensure a harassment-free environment exists.

How Oracle Plugs into the Cloud Native Dashboard Grafana

This week, for the GrafanaCon being held in Los Angeles, Oracle has released a plugin to expose the Oracle monitoring service as a Grafana data source. Grafana is an open source visualization and alerting tool for time series data. This means you can visualize Oracle Cloud Infrastructure data in your Grafana instance and use it to create beautiful and useful dashboards. The work comes from Oracle Cloud Native Labs, which empowers the next generation of cloud practitioners with a curated set of solutions, tutorials, and best practices, all designed to spark inspiration, drive hands-on experiences, and unleash our industry’s potential. From the company’s certified and managed Kubernetes service built on open standards, to the cloud native Java microservices framework, Helidon, and the release of the WebLogic Kubernetes operator, Oracle believes in providing more open, cloud native development options to all users.

How to Lead Teams to DevOps Maturity

In this contributed post from CircleCI, Rob Zuber discusses the three pillars of DevOps maturity and why they’re so important. The three pillars are 1) a culture of collaboration and trust, 2) a focus on automation and tooling, and 3) a commitment to measurement and continuous improvement. If you don’t have a culture of collaboration and trust, you might have a culture of blame and silos. Automation frees up the staff to solve new problems. Automated systems give you reliable feedback, and that feedback is how you improve.

On The Road


Cloud Foundry Summit North America
Come join The New Stack for a short stack in historic Philadelphia! Digital transformation is not about adopting a single new technology — it’s about adapting to a world that’s now ordered around technology. To build for the future, your organization must develop new systems for constant learning and the ability to turn on a dime. A huge part of this is designing an interoperable IT strategy in which your chosen technologies work in tandem as part of a multi-platform strategy. Your organization’s success will be measured by the ability to master this new state of change — now and in the future. Thank you Cloud Foundry and Pivotal for making this breakfast possible. Register now!

Technologists building and managing new stack architectures join us for short conversations at conferences out on the tech conference circuit. These are the people defining how applications are developed and managed at scale.
Free Serverless Ebook

Experts and visionaries in distributed systems believe serverless technologies are the next evolution of application infrastructure beyond microservices. Leading edge companies have already embraced serverless and have dramatically reduced operational overhead and streamlined the DevOps cycle, while increasing scalability and resiliency. Still, there are many challenges to serverless adoption, such as operational control, complexity and monitoring.

The New Stack’s Guide to Serverless Technologies will help practitioners and business managers place these pros and cons into perspective by providing original research, context and insight around this quickly evolving technology.
