deployment requirements are relatively simple, the deployment problem and resolution become complex as the size of the system deployment nodes increases, the requirements for cross-datacenter deployment and service SLAs are higher. To prevent teams from repeatedly solving the same problem, Amazon built an on-premises system, Apollo, so that the team no longer reduces the speed of releasing new features because of deployment. It is reported that thousands of engineers per day in the Amazon to de

With the idea of devops, continuous delivery, and so on, the micro-service architecture is beginning to come into our vision.So is microservices the industry's long-awaited solution? Or is microservices simpler than the overall solution?Let's define the MicroServices first:MicroServices are built with a small set of services that operate independently in different processes, interacting between services through a lightweight communication mechanism, s

Speaking of this, you may have understood the relationship between the EP team and other technical teams: the EP team is like the automobile manufacturing industry, providing efficient and low-consumption tools; the product technical team is like the logistics industry, use tools to quickly advance and create user value. They are independent of each other. Who ha

Advantages and disadvantages of micro-service architecture Previously reprinted an article on the Micro-service architecture written by Martin Fowler: "Micro-Service (microservices)". Today, I will reprint an article summarizing the advantages and disadvantages of this architecture. Reprinted from: "Micro-service, make the development process simpler or more complex." , the debate on micro-service architecture: simpler or more complex. 》。 With the concept of

As this picture shows, in the Spring IO framework, Spring boot is in the execution layer to see the official explanation for this layer:The Spring IO execution layer provides domain-specific runtimes (DSRs) for applications built on the IO Foundation modules . A DSR may run standalone without requiring deployment to an external container.Or cite the official words to illustrate what spring boot does primarily:Spring Boot reduces the effort needed to create Production-ready,

ObjectiveToday's microservices architectures are popular, and microservices-based systems also bring clarity to business segmentation and scalability. At the same time, the technology stack that supports microservices is also diverse, and this series focuses on the leading--spring Cloud in these technologies. This is a preface to the main story of why we chose Spring Cloud and its technology overview.1. Why the MicroServices architecture requires spring CloudTo put it simply, the core of service

Every day, there will be a lot of hype about new languages and databases. But what technologies are actually used? Will the technologies used by good start-ups be different from those used by poor ones? Angellist's self-report can reveal some of our answers. You can find that mongohood uses python, Django, and iOS, and secret uses Java, go, Python, JavaScript, HTML5, CSS, IOS, and Android. Angellist divides these enterprises into three levels: one is "pass", and the technology used is represente
