What is the significance of information technology?

It’s been said that data is what drives the world’s industries. That may be a stretch, but few firms, big or small, can stay competitive without the ability to collect data and turn it into actionable information. IT enables the development, processing, analysis, exchange, storage, and security of data.

So, how does IT play a role in day-to-day operations? Consider the following five scenarios involving IT and teams at work:

Upgrade the server.

A data centre server or servers nearing the end of its operational and maintenance lifetime. IT staff will select and procure replacement servers, configure and deploy the new servers, back up applications and data on existing servers, transfer that data and applications to the new servers, verify that the new servers are operational, and then repurpose or decommission and dispose of the old servers.

Surveillance for security.

IT staff receive alerts of potential threats or noncompliant behaviour — such as a user attempting to access a restricted file — check logs and other reporting tools to investigate and determine the root cause of the alert, and take prompt action to address and remediate the threat, often driving chasms between businesses.

New software has been installed.

The company finds that a new mobile application is required to allow consumers to log in and access account information, as well as complete other transactions, via their smartphones and tablets. Developers labour to design and improve a suitable application in accordance with a set of guidelines. Each iteration of the new mobile application is posted for download, and the back-end components of the app are deployed to the organization’s infrastructure.
Enhancement of the business. To help with revenue or business continuity initiatives, a company needs higher availability from a crucial application. IT workers may be asked to design a high-availability cluster to provide better performance and resilience for the application, ensuring that it can continue to function even if a single component fails. This can be combined with data storage protection and recovery improvements.

User assistance is available.

Developers are working on a significant upgrade to a critical business programme. Developers and administrators will work together to generate updated upgrade documentation. IT personnel may deploy the upgrade for restricted beta testing, allowing a small group of users to try out the new version while also preparing and delivering extensive training to prepare all users for the new version’s final release.
