Database Schema Migration Tools

In the present case, it is clear that the enterprise can choose to verify the cloud application migration business case. It also shows that the technical problems associated with cloud migration can ruin business cases, disrupt applications and even produce other aspects of performance and stability of such applications. Application architects who consider implementing cloud migration need to review their entire application lifecycle management (ALM) processes. Otherwise, they should pay special attention to managing performance and reliability, ensuring compliance and security, and ensuring operational efficiency and stability in cloud computing. In general, deployment, redeployment, mainly through manual operation ...

Companies are clearly able to choose a business case for verifying cloud application migrations. However, it is clear that the technical problems associated with cloud migration can ruin business cases, disrupt applications and even generate other aspects of application performance and stability. Application architects who consider implementing cloud migration need to review their entire application lifecycle management (ALM) processes. In addition, however, they should pay special attention to managing performance and reliability, ensuring compliance and security, and the emphasis on ensuring operational efficiency and stability in cloud computing. Typically, deployment, redeployment, and management is done primarily through human operations ...

Editor's note: This article from Liouville Contribution (micro-blog @ Liouville Life Road), engaged in the cloud computing industry for many years, from personal experience, and with some Google, Jingdong and other companies cloud computing architects to share the experience of the summary, for you to analyze what is a "shared database." What is a shared database talking about "shared databases", what puzzles us most is "sharing" three words. "Sharing" lets us think of the antonym "exclusivity".

Currently, the vast majority of large, old, and single applications in the IT industry are not portable and must be rewritten to suit the target environment. The portability of applications has cost everyone a lot of time and money. Not surprisingly, the purpose of application migration in cloud computing is to make applications more portable in a way that is cloud computing. There are at least three things we can do: make the architecture of the application more reasonable to improve its portability in the cloud, develop open standards for cloud computing, and look for applications that can be implemented in the cloud without modification ...

The appearance of MapReduce is to break through the limitations of the database. Tools such as Giraph, Hama and Impala are designed to break through the limits of MapReduce. 　　While the operation of the above scenarios is based on Hadoop, graphics, documents, columns, and other NoSQL databases are also an integral part of large data. 　　Which large data tool meets your needs? The problem is really not easy to answer in the context of the rapid growth in the number of solutions available today. Apache Hado ...

It has been almost 2 years since the big data was exposed and the customers outside the Internet were talking about big data. It's time to sort out some of the feelings and share some of the puzzles that I've seen in the domestic big data application. Clouds and large data should be the hottest two topics in the IT fry in recent years. In my opinion, the difference between the two is that the cloud is to make a new bottle, to fill the old wine, the big data is to find the right bottle, brew new wine. The cloud is, in the final analysis, a fundamental architectural revolution. The original use of the physical server, in the cloud into a variety of virtual servers in the form of delivery, thus computing, storage, network resources ...

The implementation of the "TechTarget China original" Large data solution has put many IT departments in a dilemma.
