A software application engineer manages computer systems, installs and maintains servers, monitors applications, configures the entire system, and ensures service level agreements are met. They work in data centers and use advanced tools to track system health and maintain system availability.
A software application engineer is an individual responsible for managing the day-to-day maintenance of a computer system. He is typically responsible for installing, configuring, and maintaining multiple servers. This includes planning for server upgrades and outages due to infrastructure issues.
When a computer application is installed, it must be monitored to ensure that it functions correctly. The software application engineer uses advanced monitoring tools to track the computers in the system for which he is responsible. This monitoring software alerts the engineer when a problem is identified. These issues include hardware failures, network issues, and potential cyber attacks.
Software applications are a complex grouping of hardware, software, and networked telecommunications devices. This complex grouping requires proper configuration and enterprise planning. The software application engineer is responsible for managing the configuration of the entire computer system. Such detailed configuration management is critical to ensuring systems maintainability.
The software application engineer typically works in a data center. A data center is a building designed to manage multiple computer systems. This is a facility designed to support large computers, with special provisions for redundancy, advanced cooling and power backup. The data center provides a secure environment, protected from physical and electronic intrusions. The system administrator is the only person with access to computers in a data center.
Each software application has a service level agreement (SLA) that defines the required stability of the application. The software application engineer is responsible for ensuring that each SLA is adhered to. This SLA is the contract between the software vendor and the production environment manager.
SLAs are an extremely important topic for most large organizations. These large companies require that the availability of the IT infrastructure matches the organization’s business objectives. When a system is not available, revenue is potentially lost; therefore, system availability must be constantly monitored. The systems engineer uses advanced tools and software to track the health of the computers he is responsible for.
An online reservation system on the Internet is a good example of an application with a critical SLA. The software application engineer is responsible for ensuring that the reservation system is available 24 hours a day as failure would result in lost revenue. With the move to cloud computing, this requirement will become more relevant because all future applications will be supported over the Internet via software as a service (SAAS) strategy.
