In this post, we talk about the 5 most common causes of system unavailability and how to combat them effectively.
1. Storage failures
They are considered as the main reason for the unavailability of systems, especially in services that work in the cloud. It is important to remember that a cloud service, paradoxical as it may seem, works in one place physically and that if it fails, there will be a reduction in system performance.
To avoid this type of problem, it is important to consider these operational failures even during application development, using data redundancy techniques to ensure system availability.
2. Loss of databases
Another very common problem that causes data unavailability is the loss of the database, which can indicate problems with SQL or even some kind of data corruption. Usually the reason is that malicious users or programs delete or corrupt information, rendering systems unavailable.
When this happens, the database must be rescued and recreated from backup, so it must always be up to date. It is also important to develop tools that track actions of change to discover what may have happened and who is responsible for the problem. In some difficult situations, hiring IT services like Managed IT Services Dallas is recommended.
3. Security violations
Cyber attacks are very common problems and actions to avoid them should be among the first concerns during system development.
If the system works in the cloud or in the local area, security breaches can occur. However, cloud providers are very concerned about information security. Therefore, it is necessary to develop a tool that tests the system and can identify security gaps.

4. Human faults
It’s usually a simple bug that goes unnoticed during development, such as script typing errors, but can lead to system downtime. Incorrect codes can cause feature conflicts and open doors for attackers. Until the bug is identified, many hours of work and development will be lost.
To avoid this type of problem, it is very important to invest in a quality testing team that can identify these errors even before sending a system for production.
5. Natural disasters
Many systems are installed in the physical premises of the organization, but in the event of a disaster such as fire, application data will be lost. Because it is not possible to predict this type of situation, it is important that the company adopt a cloud infrastructure and an IT contingency plan.6. Lack of update
The lack of updating of both the users’ computers and the application itself is another factor that contributes to the lack of availability of the systems. An unrepaired computer can be vulnerable to attack, and systems that do not provide updates cannot resolve problems that were not detected during development. It is important to maintain a regular automatic update plan.
There are a number of causes for system unavailability, and while challenging, they can be avoided even before they occur. And efficient IT teams must be vigilant, as these problems can cause financial losses to the business and affect user performance.
