Unplanned server downtime can result in a chain of unprecedented negative occurrences, including data failure, lost revenue, decreased employee productivity, customer dissatisfaction, brand damage, and more. When it comes to managing server downtime, whether planned or unplanned, it’s essential to establish proactive prevention measures.
Although downtime events may vary, it’s evident that the direct and indirect cost implications are vital to your business’s bottom line. However, the good news is that there are reliable solutions that can help mitigate or completely eradicate the costly downtime.
A high availability clustering system like this is one of these possible solutions that can help eliminate unplanned downtime, improving your server uptime. Furthermore, this cluster solution can be used to automate applications and implement Linux clusters.
High availability clustering solutions also allow for continuous server monitoring, and when a fault occurs, the workload is safely moved to a different server host. This is a great way to ensure business continuity and reduce unplanned downtime.
Here is what every business professional should know about unplanned server downtime.
Causes of unplanned server downtime
Unplanned server downtime can occur due to several reasons. Some of the most common include internet or power outages, cybersecurity threats, and hardware failure. Although they are unforeseen, companies can prepare to prevent them from minimizing their impact on business. They can achieve this purpose by investing in power back-up solutions like generators and use cloud-based hosting to avoid data loss. On the other hand, cybersecurity-attack is considered one of the leading causes of server downtime.
In order to minimize the impact of cyber-attacks, businesses should implement viable protection measures such as fraud detection systems, file encryption, spam filters, and multi-factor authentication. Hardware failure can also significantly contribute to server downtime.
When servers hosting your resources, data, and applications fail, it can bring operations to a standstill. To reduce this problem, you may need to invest in redundant hardware like routers, switches, firewalls, and networks.
How to configure a high availability cluster
A high availability cluster helps minimize downtime to promote continuous service when one system part fails. It consists of different nodes that interact and share information via data memory grids, ensuring high system reliability, scalability, and availability.
To configure a cluster, you need a minimum of two servers. To enable communication between the two servers, you have to set up proper local DNS settings in the host file of the two separate servers. You can then open and update the file using your preferred command-line editor.
Feel free to add your servers’ actual IP addresses. To configure the cluster and enable communication among the nodes, you need to create a secure password on every node. Start and boot each node and then start the system. Lastly, authenticate the user for each node within the cluster where you’ll be running your software.
Advantages of high availability clustering
High availability clustering is a highly efficient solution that allows your business to continue running, even when certain system components fail. Some of the benefits of a high clustering solution include protecting your company from downtime. This means that if one of your servers breaks down, a clustering solution can safely transfer operations to another server.
This solution also simplifies maintenance as it helps manage hardware and software upgrades to avoid costly downtime. Similarly, high availability clustering can also improve resilience and agility. This is particularly true because it can be customized to suit your business’s specifications. Additional benefits include providing maximum flexibility and scalability and saving you lost revenue.
Disadvantages of high availability clustering
One of the obvious drawbacks of high availability servers is the high cost. Since the system is highly efficient, it requires good hardware and design, which is more costly than a non-clustering server design. So if you’re looking to invest in a high availability server, you should be aware of its cost implication.
Another disadvantage is that it’s hard to monitor and maintain. This is because the clustering requires more hardware and servers to work efficiently. Meaning, you must have a solid plan and budget before implanting your high availability clustering solution.
