1. Avoid locking suppliers.

Too many IT leaders still think they are promoters of new technologies. Suppliers have long been catering to the idea of ​​decision makers. It also has obligations from cost center to contribution income. However, the old habit is difficult to change. A key factor is the rapid and seamless use of technology. Using technologies based on reliability and comprehensive economic analysis as soon as possible may have significant competitive advantages.

On the other hand, this needs to avoid suppliers locking. The lower the lock level, the faster the company's movement. Any technology may not be suitable for rewriting a large number of applications and re -invent the business process. Stay away from any supplier that trys to cover up their technology.

2. Does the company have to rebuild it?

For corporate engineers, there seems to be no more attractive way to start. Rewriting, rebuilding and re -invention are very satisfactory. Nothing to get rid of the past more effectively. It may really need to rewrite applications with obvious quality problems.

However, the migration from one database to another is usually driven by other factors. Usually not because of the quality problems of work applications, but because of business problems, but because of business problems. In fact, IT will have to rebuild a complete and healthy application platform.

At the beginning, it looked like an easy -to -manage project, and it would soon devour the entire business.

The method of starting from scratch will spread soon. With the progress of the plan, more and more applications need to be rewritten. Because there are not enough consultants to help solve this problem, analysts and commercial users are required to rewrite their SQL. Everyone wants to know if this is really the best use of their time.

As this ancient saying says: If it is not bad, why repair it? Just because we are looking for a more economical database platform, it does not mean that we must rebuild us in the same way after rewriting. Everything that is working.

3. Capacity migration.

The typical migration project of the data warehouse project lasts for $ 30 million within 5 years. Gartner set the success rate of these projects below 15%. Due to the company's migration to another platform, Teradata recently emphasized how heavyweight brands in this field win their customers.

If these projects have so many problems, why is the industry not better dealt with? First of all, our engineers often underestimate the efforts of software development projects.

However, the problems in migration are even more dangerous. The initial progress of this project shows that it will soon succeed. Then, 20%of the work will consume 80%of resources and ruthlessly push the cost. After several years of projects, the funds are exhausted, the business is overwhelmed, and the project collapses.

Don't be confused by the most typical issues: the first 80%of the challenges are a piece of cake. The last 20%is a problem of failure of these projects.

4. Advantages of virtualization database system.

Moving data to the cloud is not a choice, but an inevitable requirement for each IT department. However, this is not limited to this. Replacing the local database with only the hosting database does not meet the needs of IT for income. Instead, IT must find out in the depth integration of how to transition from today's data island (based on cloud) to the cloud database lte iot.

In the cloud, the data warehouse is the pillar of all new IT environments, and it may be the most difficult to move. If the perfect migration is performed, the bet is large, but the return is also very high.

The virtualization of the database system brings the gap between the old and the old: the existing application can be quickly transferred from the current database to the new database. There are no major changes. At the same time, the company can build a new application on the new platform. In short, the virtual database system provides the best advantage for enterprises.

Experienced IT leaders should understand that compared with rewriting applications, the benefits of new development deployment resources and funds are much higher. In today's world, the speed of technology is faster than ever.
