Feelings about Sina cloud computing platform Sina App Engine

Today, I checked Sina's public cloud computing platform Sina App Engine. I just looked at development-related things and didn't actually do anything. I feel that there are still some gaps in conventional Web servers.ProgramIt should take a bit of effort to transplant (this should be consistentCodeThe writing quality is related, and a good design should not be changed much ).

After reading the development instructions, I feel that there should be no major problems in general, but the restrictions on the number of connections/memory may be problematic for some special applications, the maximum number of concurrent connections is 500, which should not be too high for common applications. A 64 MB memory ceiling is set for a single page script and cannot be modified on its own. This common application cannot use so much memory, however, some special applications may occupy more memory. They once used the attachment encryption function, in which memory usage is relatively large and such restrictions may cause some problems. Because of the distributed problem, the local I/O part may need to be modified to adapt to the distributed system architecture.

What is not quite good yet is the CDN feature, which also provides some mainstream front-end frameworks by default, such as jquery, mootools, prototype, Yui, and other general JS/CSS frameworks, jquery-UI Based on jquery is advantageous for self-built servers. However, after reading the jquery-UI usage method, it should be all introduced, which will waste some traffic, because not every application needs to use all components.

The general feeling is good, and we look forward to further improvement and updates. Enter an application to check what problems will occur during the development process. By the way, a certain amount of cloud beans are provided free of charge every day. It is good to put some small applications or something.
