Performance Cloud

When an enterprise migrates its core IT systems to a private cloud or public cloud network, the work is not over. 　　Now there is a different set of technical issues that need to be addressed: how to manage the cloud to ensure that the enterprise's investment returns, providing the desired efficiency and return on investment. Cloud management and cloud monitoring have become more important as the Amazon EC2 (Flex Computing Cloud) Service outage occurred this April. In that incident, the IT field saw what would happen when the cloud environment encountered a failure ...

Various new cloud performance management tools and technologies will make the visibility of applications in the cloud environment clearer. 1 milliseconds is just a short moment. But if you're a SaaS provider, with thousands of databases running more than 2 billion SQL queries a day, it's very valuable to provide 10TB of SQL data. Performance is also critical to visibility-especially when your system is connected to other providers ' systems in the cloud. This is exactly what concur technology has been doing, and it is dealing with more than 50 billion dollars a year in the cloud ...

What about cloud computing performance? It depends on who you ask. There are three cloud computing models, and which one you use determines what performance you will get. People who use software as a service (SaaS) system and process standard Web latency cannot tell you too much about performance. 　　However, those who use the advanced "large data" system will tell you something very different. You need to consider several performance patterns, the performance pattern can be divided into three non ...
