Amazon EKS now supports assigning EC2 security groups to Kubernetes pods

Amazon Elastic Kubernetes Service (EKS) customers can now leverage EC2 security groups to secure applications with varying network security requirements on shared cluster compute resources. Previously, all pods on a node shared the same security groups. While IAM roles for service accounts solves the pod level security challenge at the authentication layer, many organization’s compliance […]

Ingress for Anthos—Multi-cluster Ingress and Global Service Load Balancing

Ingress for Anthos is a Google cloud-hosted multi-cluster ingress controller for Anthos GKE clusters. Ingress for Anthos supports deploying shared load balancing resources across clusters and across regions enabling users to use a same load balancer with an anycast IP for applications running in a multi-cluster and multi-region topology. In simpler terms this allows users […]

What we learned after a year of GitLab.com on Kubernetes

It’s been one year since we moved GitLab.com to Kubernetes. We unpack the challenges and learnings from this major migration. For about a year now, the infrastructure department has been working on migrating all services that run on GitLab.com to Kubernetes. The effort has not been without challenges, not only with moving services to Kubernetes […]

Introducing Domain-Oriented Microservice Architecture

Recently there has been substantial discussion around the downsides of service oriented architectures and microservice architectures in particular. While only a few years ago, many people readily adopted microservice architectures due to the numerous benefits they provide such as flexibility in the form of independent deployments, clear ownership, improvements in system stability, and better separation […]

Cloudflare outage on July 17, 2020

Today a configuration error in our backbone network caused an outage for Internet properties and Cloudflare services that lasted 27 minutes. We saw traffic drop by about 50% across our network. Because of the architecture of our backbone this outage didn’t affect the entire Cloudflare network and was localized to certain geographies. The outage occurred […]

GNU GCC does not round floating-point divisions to the nearest value

I know that floating-point arithmetic is a bit crazy on modern computers. For example, floating-point numbers are not associative: 0.1+(0.2+0.3) == 0.599999999999999978 (0.1+0.2)+0.3 == 0.600000000000000089 But, at least, this is fairly consistent in my experience. You should simply not assume fancy properties like associativity to work in the real world. Source: lemire

Python may get pattern matching syntax

The creators of the Python language are mulling a new proposal,PEP 622, that would finally bring a pattern matching statement syntax to Python. The new pattern matching statements would give Python programmers more expressive ways of handling structured data, without having to resort to workarounds. Pattern matching is a common feature of many programming languages, […]

OpenAI releases powerful text generator

The laboratory, founded by Elon Musk and recently supported by a $1 billion grant from Microsoft, has designed text generators that create readable passages virtually indistinguishable from those written by humans. OpenAI’s machine learning approach scrapes massive amounts of data from the web and analyzes it for statistical patterns that allow it to realistically predict […]

Artificial brains may need sleep too

No one can say whether androids will dream of electric sheep, but they will almost certainly need periods of rest that offer benefits similar to those that sleep provides to living brains, according to new research from Los Alamos National Laboratory. Watkins and her research team found that the network simulations became unstable after continuous […]
