Today, more and more PAAs (platform service) providers, in the field of cloud computing has launched a fierce competition. Cloud computing works well with the development mechanism for deploying applications.     IAAS providers provide basic computing resources, SaaS providers provide online applications such as online CRM, and PAAs offerings provide developers with a one-stop service that allows our applications to start and run quickly without paying attention to some infrastructure issues. As a service provided on the PAAs platform ...

PaaS (Platform-as-a-service) is a kind of cloud service, the service provider not only provides on-demand hardware and operating system services, but also provides the application platform and solution stack. For developers, PAAs greatly reduces the cost and pain of it deployments, providing resources for applications to scale more easily as needed. JVMs, application servers, and deployment packages (for example, war and ear) provide natural isolation for Java applications, allowing different developers to deploy applications in the same infrastructure, so JAV ...

Improve Network Service resource quality, save IT cost, realize multi-point disaster prevention backup "server +IDC" is the basic mode of enterprise building IT system, but now, the pattern is changing. The disadvantages of traditional server model are obvious, the application workload is constantly changing, the single application server is often unable to meet the demand, and the rapid increase in the number of servers, will cause the enterprise capital and operating costs rise. At the same time, increasingly complex IT systems and data centers can be difficult to quickly configure and efficiently manage to meet changing needs. In every it encounter bottleneck ...
