Microsoft’s underwater data centre resurfaces after two years

Two years ago, Microsoft sank a data centre off the coast of Orkney in a wild experiment. That data centre has now been retrieved from the ocean floor, and Microsoft researchers are assessing how it has performed, and what they can learn from it about energy efficiency. Their first conclusion is that the cylinder packed with servers had a lower failure rate than a conventional data centre.

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.

In simpler terms this allows users to place multiple GKE clusters located in different regions under one LoadBalancer.

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 of concerns, in recent years people have begun to decry microservices for their tendency to greatly increase complexity, sometimes making even trivial features difficult to build. As Uber has grown to around 2,200 critical microservices, we experienced these tradeoffs first hand.
