Will JavaScript type annotations kill TypeScript?
The creators of Svelte and Turbo 8 both dropped TS recently saying that "it's not worth it".
Yes: If JavaScript gets type annotations then there's no reason for TypeScript to exist.
No: TypeScript remains the best language for structuring large enterprise applications.
TBD: The existing user base and its corpensource owner means that TypeScript isn’t likely to reach EOL without a putting up a fight.
I hope they both die. I mean, if you really need strong types in the browser then you could leverage WASM and use a real programming language.
I don’t know and I don’t care.

Honeycomb is sponsoring The New Stack’s coverage of Kubecon+CloudNativeCon North America 2020.

Obviously, these are not good times. COVID-19 deaths continue in many parts of the world. And the untimely death of Dan Kohn, former executive director of the Cloud Native Computing Foundation (CNCF) — who this writer can confirm was a genuinely kind and decent person — cast a further pall over this year’s virtual KubeCon + CloudNativeCon.

But despite everything, this year’s KubeCon proved that cloud native development and technologies are not only continuing to evolve but are flourishing. The community also continues to support diversity and inclusion for cloud native development, which were among the conference’s themes and discussions. In other words, the cloud native and open source community continues to thrive.

“It’s cloud native at its finest — as you can see, our end users are changing the world and many of you are sitting in the audience in your own homes today. That’s why end-user-driven open source is so inspiring,” CNCF General Manager Priyanka Sharma said during the opening virtual keynote. “Today, workloads are run at a scale never seen before with complexity management none of us has ever experienced. Establishing a direct feedback loop between our end users and projects has been invaluable — and further diversifies team cloud native.”

Best-Bit Observability

Observability and adopting the right monitoring system to achieve optimal visibility into application performance has emerged as a key challenge for the DevOps community. Not surprisingly, the OpenTelemetry project was a major theme at this year’s KubeCon. As a way to improve interoperability among observability tracing tools, the project was created to help create a standard for observability tools in a vendor-neutral way. In other words, OpenTelemetry will allow organizations to test and adopt tracing tools without having to create SDKs for each tool from different vendors.

“Overall, our goal is to make sure that people have one clear solution for how they’re going to add instrumentation data to their project, whether it be an open source framework or an end user or, someone working at an observability or telemetry company,” said Liz Fong Jones, principal developer advocate for observability provider Honeycomb — which supports OpenTelemetry — and a member of the governance committee of OpenTelemetry, said during The New Stack livestream podcast, “Understand Observability, Then Level Up”:

LogDNA is also engaged in adapting its “Kubernetes Enrichment” platform — introduced during the week of KubeCon — to meet the OpenTelemetry standard. The standard will help its platform better meet user specifications as a single panel for observability of pertinent events and resource metrics for Kubernetes environments, including infrastructure and deployed applications.

“With Kubernetes Enrichment, we’re primarily focusing on enabling new in-app developer workflows by exposing more Kubernetes metrics and metadata alongside logs in LogDNA,” Michael Shi, a LogDNA product manager, said.

Distributed tracing and analysis provider Dynatrace introduced its observability platform PurePath 4 platforms for transactions across multicloud environments during the week of KubeCon. While incorporating OpenTelemetry and W3C Trace Context, the tools support cloud native architectures for serverless computing for Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform and serve mesh configurations.

Additionally, Dynatrace has integrated OpenTelemetry into its open source project. “For complex systems, observability is key,” Daniela Rabiser, technical product manager for Dynatrace, said during her KubeCon talk “Batteries Included: Shipping OpenTelemetry with Your Open Source Project.”  She described how to pre-instrument OpenTelemetry for open source projects to “ensure that it’s coming with observability batteries included.”

Also during the week of KubeCon, Diamanti extended its Diamanti Spektra 3.1 “single pane of glass” console for Kubernetes environment management and Ultima data plane services to support Amazon Web Services (AWS) deployments. Spektra first supported Microsoft Azure, while the company expects to add support for  Google Cloud Platform (GCP) in early 2021.

15,000 Nodes Are ‘Already a Thing’

Even as Kubernetes moves into supporting production-level workloads, researchers are still researching the outer limits of what Kubernetes’ capabilities. New tools and platforms continue to fill the vacuum of uncertainties around the best way to deploy and manage Kubernetes in order to continually improve upon the container orchestrator.

Organizations are also increasingly able to scale Kubernetes clusters at incredible magnitudes. In his keynote on SIG Scalability at KubeCon, for example, Wojciech Tyczyński, a senior staff software engineer at Google who has been developing Kubernetes and the Kubernetes engine for over five years, described how it is now viable to manage Kubernetes clusters with 15,000 nodes.

“Clusters with 15,000 nodes are already a thing,” Tyczyński said.

While many, perhaps most, readers will work for organizations whose scalability needs will never require such a magnitude of nodes to scale, the research enabling 15,000 Kubernetes nodes will lend itself to cluster management at much smaller levels as well. “Scalability work matters for almost everyone because scalability is much more than just the cluster size — the improvements we did to push the scalability limits are also — or maybe even primarily — making smaller clusters more reliable and more performant,” Tyczyński said.

The Go programming language, and more specific to Kubernetes, the Go client for Kubernetes, has emerged as a popular and proven way to build applications for clusters.

“It may be surprising to many of you,” Tyczyński said, “But lock contention in Go memory has emerged as a major Kubernetes bottleneck.” Yet, this minor setback remains par for the course as the rate of contributions and creation of fixes continue unabated. Some optimizations for the Go bottleneck “have already landed” and “even more are coming,” Tyczyński said. “This benefits not just Kubernetes, it benefits everyone who’s writing their applications in Go,” he said.

Other recent improvements include removing bottlenecks for the Etcd distributed key-value store, relating to read and write operations. Now, when listing custom resources, spikes in the API latencies have been removed, Tyczyński said.

“With upcoming [Kubernetes] releases, you can expect even more improvements while extending the portfolio of use cases, supported by clusters with 15,000 nodes,” Tyczyński said.
