characteristics, and of course the cap theorem is constrained by the horizontal scaling partition.The scalability of the software is very important, but it is difficult to grasp, the industry is trying to save the developer energy through cloud computing or high concurrency language, but no matter what technology, if the application system is monolithic, such as heavily dependent on the database, the system reached a certain level of access, The load is concentrated on one or two database serve

skyscraper isn ' t supposed to the change it location or height. Skyscrapers aren ' t scalable.We cannot easily add lanes to roads, but we've learned how to easily add fea-tures to software. This isn ' t a defect of our software processes, but a virtue of the medium in which we work. It's OK to release an application that is only does a few things, as long as the users value those things enough to pay for them. In fact, the earlier you release your application, the greater the net present value

Body: In the past few days, the customer has recommended a CMS system umbraco, hoping to make it a product for a general company website. After studying it, it feels very simple, but it is highly scalable. Umbraca really only does what CMS should do, so it is simple, but its content definition method makes its scalability very powerful. The default installation environment of umbraco is a hosting host that has never been used before. If you w

Chapter 6th of. NET Design Specifications: scalable design,Chapter 2: scalability design 6th Extension Mechanism Consider using a non-sealed class that does not contain any virtual or protected members to provide scalability for the framework. The scalability provided by this method is widely welcomed by users, and its overhead is not high. Consider using protected members for advanced custom solutions. When analyzing security, documentation, and comp

Scalable markup language XML 1. What is XML first? XML is short for eXtensible Markup Language. In the. NET Framework, XML is a very important part. It is used to describe data and is a powerful tool for processing structured document information. 2. XML has the following features: ① No pair of tags in XML are usually called nodes. They appear in pairs and must appear in pairs to describe the content stored on this node. ② Each node used to describe
