Infoq has also published several articles, such as "Introduction to Virtualization" and an article on virtualization security, but there is still a lack of comparisons between different cloud providers. This article compares three cloud computing providers, which provide a server-centric solution, starting with a description of how to start three cloud computing services and then comparing the performance, price, and availability of services to three service providers. ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem. Such a simple service is bound to bring many challenges to the unprepared IT department. 　　We've been through this many times before: the benefits of a technology that are easy to use end up being an unexpected management challenge, such as virtualization, which causes virtual machines to become fragmented, new security risks to smartphones, and instant messaging that triggers corporate governance problems.

Do you just follow the document and technically put it to the correct implementation? How to do this is the most important information a developer needs to know in a team life. But, in part, this is the only thing developers need to know about the project. But we can't see it that way. If you don't know what you're doing, even the most efficient ruby ...

Server era: Before the cloud service, developers need to consider the server before the development of the application, and make a series of preparations to pay, plan, connect, and maintain it.
