A network administrator is nowadays becoming increasingly responsible for tasks that are purely based on software. Increasing global networking has revolutionised the job profile of network professionals, just like a traditional IT administrator.
A number of technologies whose installation and control is much more complex than any technology from just a few years ago, are grouped together under the collective term cloud.
The virtualisation of server infrastructure, which promises companies a more flexible and decentralized control, as well as better scalability, plays a very important role. Due to the rapid and widespread growth of broadband internet connections this is technically no longer a problem in industrialised countries.
Network administrator for IaaS, PaaS and SaaS
While a traditional network administrator is responsible for the local IT infrastructure and for ensuring that the hardware cable and WLAN networks run error-free, a virtual network administrator is specialised in the complex control of cloud-based services.
IaaS – Infrastructure as a Service
Complete Windows systems can be entirely virtualised nowadays with VMware, Microsoft Azure, Citrix and similar platforms. Instead of real hardware, the corresponding systems are used as virtual machines. If the server infrastructure required runs on Linux or Windows will depend on the specific case.
The necessary server and data transfer capacity are purchased according to need or flexibly calculated, and the entire management of the entire systems is done directly in the cloud.
PaaS – Platform as a Service
Managing PaaS systems also requires a trained network administrator. Platform as a Service refers to services that a web application developer will provide in the cloud in a specific computer platform. There are also services for collaborative work and versioning, for monitoring, for security or middleware services for storing data. The line between PaaS and IaaS is flexible, which mean a network administrator will often need to look after both. In PaaS services many parameters will need to be regulated with APIs, while in virtual infrastructure network protocols, ports and the assignment of rights is in the spotlights.
SaaS – Software as a Service
Software as a Service (SaaS) is software that runs purely in the cloud, and plays an important role for a virtual network administrator. Many IaaS and PaaS providers operate a complex SaaS interface to manage their services.
In addition to user management, rights and quotas, as well as the networking of all systems and services used, security is also very important for a modern network administrator these days.
The emergence of cybercrime has increased by leaps and bounds in recent years, and while a few years ago hackers targeted specific victims, automated bot networks are now a central focus. With automatic detection of vulnerabilities and the fully automated infection with malware, cyber criminals like to concentrate on poorly protected or old IT systems. Only a network administrator who is trained in security is able to protect these sort of highly networked IT systems accordingly.
