Disaster Recovery Construction of Integrated Platform for Tertiary Hospitals
The integrated platform for a Tertiary Hospital faces various challenges, including a large volume of data and the criticality of uninterrupted service to avoid disruptions in the hospital's related businesses. Some hospital management personnel have reported feeling uneasy about the stability of the platform and have had to respond immediately to emergency calls on site.
Therefore, ensuring the stability of the integrated platform and having a robust disaster recovery plan are crucial. Among the well-known solutions are cold backup, hot backup, active-active, and clustering.
The disadvantages of cold backup
In the construction of an integrated platform, some vendors can only provide a cold backup solution. The technical implementation of cold backup is relatively simple.
However, cold backup has the following issues:
The core issue is that when a problem occurs, it cannot automatically switch to the backup machine. The user needs to discover the problem and manually switch to the backup machine, which leads to a long interruption in hospital operations.
Other problems include:
- The overall running efficiency of the servers is extremely low, with a resource utilization rate of less than 50%.
- There are performance bottlenecks in the platform.
To address the shortcomings of manual switching, Odin offers a hot backup solution
The hot backup solution provided by Odin can automatically switch to the backup server to process business when the main server encounters problems. Users often cannot perceive the switching process between the main and backup servers, ensuring that the system can continue to operate while also meeting the real-time requirements of high-demand businesses.
However, since the hot backup server only receives low-level data synchronization from the main server and cannot function as an independent business processing server, it only provides a time window for administrators to repair the main server. Therefore, the overall resource utilization rate of the server remains less than 50%, and the hot backup solution only has one server running, making it difficult to meet the future needs of Tertiary Hospitals for processing large amounts of data, and cannot solve the "other problems" in the cold backup solution in terms of performance.
To solve the problem of performance bottlenecks and low running efficiency, Odin provides an active-active solution.
Odin's active-active solution deploys multiple servers without a primary or backup distinction, all of which can process project business simultaneously. This increases overall resource utilization and solves the problem of idle backup servers in the hot backup solution, while ensuring high availability and solving the performance bottleneck issue of a single server.
However, the active-active or multi-active solution still faces challenges such as inconsistent management and monitoring, as well as synchronization issues. Any configuration changes made on one engine require manual synchronization with other engine servers. Additionally, this solution is not suitable for projects with strict message processing order requirements, as messages are evenly distributed to multiple servers, which may not guarantee the original processing order.
Is there a solution that can address all the shortcomings of cold, hot, and active-active backup, and achieve "high availability, performance, efficiency, and synchronization - all of them" requirements?
YES!
Suitable solution currently available —— Odin's cluster solution
Odin's Cluster Solution: Resolving the Deficiencies of Hot Standby and Active-Active Solutions
Odin's Cluster Solution separates functions such as management, monitoring, production services, and data storage, and utilizes load balancing to construct a clustered system that achieves consistent configuration, multi-point operation, and consistent data through a sound technical architecture.
Multiple servers run business operations simultaneously in Odin's Cluster Solution. Even if one server fails, other servers can seamlessly take over the business, avoiding business interruption caused by server failure and ensuring continuous operation.
Odin's cluster solution solves performance issues as well
Odin's cluster solution improves the overall processing capability of the system through a cluster architecture. With the help of load balancing, it provides an efficient and reasonable dynamic task allocation mechanism that further enhances the overall operational efficiency of the system, ensuring high performance in most medical data application scenarios.
The difference between Odin cluster solution and general cluster solution: Odin is an application-level software cluster, not an operating system-level cluster, which results in different implementation effects
Some vendors provide cluster solutions at the operating system level to achieve high availability by implementing hardware and operating system-level failover. However, this kind of solution is difficult to fully utilize hardware resources.
Odin's cluster solution is an application-level software cluster developed for the specific business requirements of hospital platforms. It distributes services across multiple servers to run simultaneously, and can be dynamically expanded while achieving high availability and high performance.
