Optimising for High Latency Environments

CSS Wizardry

We really don’t deserve it, but I digress… That said, one of the key improvements in HTTP/3 is that, because it’s built on top of QUIC, which in turn has the benefit of access to the transport layer, it is able to provide TLS as part of the protocol. Cache Everything If you’re going to do something, try only do it once.

Kubernetes in the wild report 2023

Dynatrace

Of the organizations in the Kubernetes survey, 71% run databases and caches in Kubernetes, representing a +48% year-over-year increase. Together with messaging systems (+36% growth), organizations are increasingly using databases and caches to persist application workload states.

World’s first and only fully automatic observability for Golang services now extended to statically linked Go applications

Dynatrace

Checking the code references of these methods reveals that all leaking goroutines were started by the method type http.Transport , which is defined in the Go standard library package net/http : func (t *Transport) dialConn(.) { //. From http.Transport documentation : By default, Transport caches connections for future reuse.

Simple streaming telemetry

The Netflix TechBlog

The mechanisms by which the data is retrieved may not be inherently reliable (in the case of SNMP’s UDP transport) and always require active polling by the collector?—?which, After an instance of gnmi-gateway acquires a lock for a target and forms a connection, it begins to forward data into the local in-memory cache.

Pushy to the Limit: Evolving Netflix’s WebSocket proxy for the future

The Netflix TechBlog

This generalized message means that device teams are able to define their own protocols on top of these messages — Pushy would just be the transport layer, happily forwarding messages back and forth. For these requests where caching removed KeyValue from the hot path, we were able to greatly speed things up.

HTTP/3 From A To Z: Core Concepts (Part 1)

Smashing Magazine

For example, while HTTP deals with URLs and data interpretation, Transport Layer Security (TLS) ensures security by encryption, TCP enables reliable data transport by retransmitting lost packets, and Internet Protocol (IP) routes packets from one endpoint to another across different devices in between (middleboxes). What Is QUIC?

What is? OpenTelemetry??An open-source standard for logs, metrics, and traces

Dynatrace

Pools the data using SDKs, and transports it for processing and exporting. This occurs once data is safely stored within a local cache. Here are the steps the solution takes, and the data it generates along the way: Instruments your code with APIs, telling system components what metrics to gather and how to gather them.
