As a next-generation Internet protocol, migration to IPv6 is the general trend in the future. However, due to the large-scale application of the IPv4 protocol in the current Internet, there is no way for users to specify a time and date. From that moment on, all devices on the Internet will use IPv6, which is unrealistic. One-time migration is not only unfeasible at the infrastructure level, but for enterprise users, even if the infrastructure can be prepared, it is unacceptable for enterprise users to shut down at least hundreds or even thousands of application instances for a period of time for protocol stack migration, no matter in terms of risk or cost! Since it cannot be done in one step, gradual IP address migration has become the current mainstream choice. This article will introduce some mainstream gradual IP address migration methods.

After several years of development, Service Mesh is an emerging concept, which has attracted the attention and pursuit of mainstream technology companies from all over the world since its launch. The full name of Proxyless Mesh is Proxyless Service Mesh, which is a new software architecture developed on the basis of Service Mesh in recent years. The ideal of Service Mesh is full, but the reality is very skinny! Although there is no intrusion to the application through a layer of proxy, the increased network proxy overhead poses many challenges to the implementation of many Internet services with high performance requirements. Therefore, Proxyless Mesh, as a compromise between the traditional intrusive microservice framework and Service Mesh, provides an effective solution for a large number of non-Service Mesh applications in the cloud-native era, embracing cloud-native infrastructure, and solving pain points such as traffic management. This article will introduce Spring Cloud Alibaba's exploration on Proxyless Mesh.

Static compilation and optimization of Java applications before running based on GraalVM can significantly solve the long-criticized problems of long-term cold start and large memory usage of Java applications, and achieve cost reduction and efficiency increase! This article will introduce how to use Spring Cloud Alibaba 2022.0.0.0-RC1 version, and how to use GraalVM to statically compile and optimize Spring Cloud Alibaba applications.
