Based on the above problems, we created an all-in-one open source SDK, EasySDK to help you effectively solve the…
Now is the best time to develop operation and maintenance (O&M) more professionally.
Lu Tang, who is in charge of elastic computing stability at Alibaba Cloud, mentioned that, “Ops was created only with experience without officially being considered as a specific field. Now, based on the previous experience, it provides standardized services to the outside world.”
He believes that this era helps make O&M truly professional. Accordingly, O&M personnel can reduce costs and improve efficiency for enterprises with their skills and experience. However, this can be a challenging time for many O&M professionals. …

Netty is a high-performance network communication framework widely used in the Java language. Many Remote Procedure Call (RPC) frameworks are implemented based on Netty. In Golang, getty is a high-performance network communication library similar to Netty. It was developed originally by Yu Yu, the project leader of dubbo-go, and used as an underlying communication library of dubbo-go. As dubbo-go was donated to the Apache Software Foundation, getty finally joined the Apache family under the joint efforts of community members. Then, it was renamed dubbo-getty.

When talking about methodology, Xiang, a technology expert of AMAP said, “Complicated problems should be simplified while the simple ones should be deepened.”
This statement deeply touched me, and I believe it also applies to writing code. In other words, after splitting a complex logic into lots of simple logic, and then implementing each simple logic in-depth, the simple logic is integrated into complex logic. The quote above can be summed up as, “changing complexity into simplicity, from simplicity to complexity.”
Writing Java unit testing cases simplifies complex problems, breaking down a complex piece of code into a series of…

With the rapid development of edge computing, more data needs to be stored, processed, and analyzed at the edge of the network. Devices and applications on the edge are growing rapidly. Managing the resources and applications efficiently on the edge has become a major challenge in the industry. Currently, the cloud-edge-end unification architecture has gained wide recognition in the industry. In this architecture, the cloud computing capability is delivered to the edge in a cloud-native way and is scheduled and managed on the cloud in a unified manner.
In May 2020, OpenYurt, Alibaba’s first cloud-native edge…
