1. Application Architecture Matches Business Growth and Operations Capability At industry conferences, in documents and blogs, we constantly see all kinds of excellent solutions — but if you copy them straight into your own business, you keep hitting walls. Because these technical solutions were incubated in specific business scenarios; different business forms, different business scales, and different stages of business development all affect how technology lands.

1. Meaning If a service has multiple domain entry points and accessing it through any of them yields the same content, those domains are called peer domains. For example, through peer domains you can provide three identical file or API services. https://server.chenshaowen.com/static/index.html https://server-peer-a.chenshaowen.com/static/index.html https://server-peer-b.chenshaowen.com/static/index.html 2. Uses 2.1 Raising the Browser Concurrency Limit Browsers usually cap the maximum number of concurrent requests to a single domain at no more than 6 per second.

1. Choosing a Communication Protocol Ops systems are better suited to HTTP than to gRPC. More ops and R&D engineers are familiar with HTTP than with other protocols. Once you know the HTTP protocol, learning a RESTful-style HTTP API is quick. Being familiar to more people and easier to learn means better communication and lower handover cost, because they share more common domain background.

The hard part of a monitoring system is storing large volumes of time-series data and providing high-performance query capability; the hard part of an alerting system is designing an efficient alert engine and implementing a flexible alert escalation mechanism. I have been tracking monitoring and alerting systems for a while now, and this post mainly organizes some of the concepts, components, and research options related to monitoring and alerting.

Have you ever thought about how to design a large enterprise system? Before starting any major software development, we first have to pick a suitable architecture. That architecture has to give us the functionality and the quality guarantees we need. So before applying these architectures to our design, we should understand the different architectural systems.
