Data center migration: how to make sure your server is completely fault-tolerant

Data center migration, to ensure that your server is always in the normal running time, regardless of Hongkong server or Chongqing server, you need to confirm a question: how is your server fault tolerance? If a part of the system stops working, can your online business still operate normally? Can hardware faults and software faults be detected and processed quickly? If your site, application, or network system does not have a proper fault tolerance mechanism, then once a component in your system stops working, your business may crash immediately.

However, building a truly fault-tolerant system is a major challenge, especially when your application infrastructure is complex enough. So what do you need to do well? How do you ensure that your server is completely fault-tolerant? How do you ensure that your server and its hosted network deal with the crisis accurately and quickly? Cicada cloud for you simple introduction.
First of all, you need to understand what redundancy is and how to build redundant systems. We say, in application design, a dependency may affect the entire application, and, in the server and managed infrastructure, any detail of the fault point may cause your server to stop working. This means that when you set up and maintain the server, you need to carefully analyze each application, hardware and network nodes, any link failure, may make your system offline. You need to make sure this doesn't happen.
First, redundant power supply
You need to make sure you have redundant power supply, including enterprise class UPS, regular standby generators, etc.. Although power outages may happen only occasionally, data centers without redundant power may cause your Hongkong server / Chongqing server to be temporarily interrupted due to a short class of power failures. Therefore, selecting data centers is important, and well-designed power systems will address local power failures, voltage changes, and short-term and long-term power outages.
Two, server hardware redundancy
Hardware is very important. Whether Hongkong server rents or Chongqing server rental, server hardware and network hardware should be built in a redundant way. If your service provider and data center are responsible enough, these facilities should be available. Among them, Hongkong server rental, usually access to a number of international routes, to BGP intelligent switching best route, to ensure network redundancy, by the way, the cicada cloud Hongkong server leased, has access China Telecom CN2 line directly to Hongkong, mainland visit faster and more stable. As for the redundancy of server hardware, the RAID disk array is generally required to be paid by customers, which can provide higher data reliability.
Three, maintain the latest version of software and patch update
You need to keep software updates, especially security related content. After all, a large number of service interruptions are caused by application failures, such as elastic load balancing software failures, etc.. Moreover, without updating the version and security patches, it is easy to be hacked, leading to more serious damage.
Four, server hardware fault monitoring
Providing close monitoring for hardware facilities is essential. You should always keep a close eye on the server hardware and software, and make sure that there is a system that alerts you when the crash happens. Of course, reliable Hongkong server leasing and Chongqing server rental service providers will deploy such real-time monitoring system. You should make sure that the service provider has such a deployment when choosing a server rental.
Five, reduce the error rate of human operation
In the event that causes online business stagnation, most cases are not caused by servers or data centers, but rather by application failures, system defects, and human error manipulation. Therefore, you may need to improve server management level.
