Topology We built a dedicated backend network specifically for distributed training. To support large language models (LLMs), we expanded the backend network towards the DC-scale, e.g., incorporating topology-awareness into the training job scheduler. We designed a two-stage Clos topology for AI racks, known as an AI Zone.

One neat thing about the implementation of Suppress as an operator, rather than an option on the count or window definition, is that both the raw and final streams are available in your topology. If you have a suppression in your topology, and you write some test data, no amount of waiting will make the results come out.

At the core of each shared state microservice we built was a Kafka Streams instance with a rather simple processing topology. Additionally, our processing topology includes a second key-value store for scheduling. We used it with the WALL_CLOCK_TIME type. For achieving one-time tasks, we used the cancellation handle returned by it.

Why do we need to create site-to-site VPNs or some sort of modern SD-WAN topology connecting all our branches when almost all traffic goes to the public internet and the cloud? The result of moving resources to the cloud and using SaaS is that the very concept of branch office routing has also changed. I know there are always exceptions.
