Method 1. The most common method is to hire your own in-house engineers to build the infrastructure. Particularly in medium to large companies, infrastructure engineers and application-specific engineers tend to be separated. The advantages are that since we are in-house engineers, it is easy to collaborate, it is easy to check the progress, and it is easy to request corrections such as specification changes.
However, on the other hand, in-house engineers may have disadvantages such as their work being individualized and their ability to keep up with new technology. In addition, when hiring a new Special Data network engineer, the recruitment and training costs are not trivial. Method 2. Outsource infrastructure construction Recently, cloud servers have become popular, and an increasing number of companies are outsourcing their infrastructure construction work.

By using cloud servers, maintenance is easier for the vendor than with regular servers, and the ordering side can entrust the work to a company that specializes in technology that cannot be handled by in-house engineers, so there are benefits for both parties. Issues include the security risk of disclosing internal confidential information to the outside. The current situation is that some companies are unable to outsource due to this concern.
