Infrastructure Engineer
An engineer who builds infrastructure environments is called an infrastructure engineer. Infrastructure engineers build the foundation needed to run applications created by programmers or system engineers, such as server construction and network construction.
In contrast to handling the visible front side such as apps, web pages, and other front-end areas, they handle back-end work behind servers and operating systems.
People who work on infrastructure foundations are called infrastructure engineers. Types of infrastructure engineers include the following.
- Network engineer
- Security engineer
- Server engineer
- Database engineer
Work of an Infrastructure Engineer
Infrastructure engineers design and build IT infrastructure, and perform operations and maintenance so it works without problems.
- Requirements definition
- Listen to the customer’s requests and decide what kind of IT infrastructure to create.
- Design
- Decide what devices to use and what configuration and setting values to set.
- Also consider what rules will be used to operate it after it starts running.
- Construction
- Procure equipment and actually perform construction tasks such as connecting devices.
- Testing
- Check whether it operates without problems according to the design document.
- Maintenance
- Monitor whether it is operating normally and resolve problems when errors occur.
