The Redis cluster is an assembly that provides data sharing between nodes in multiple Redis. redis3.0 Previously, only support master-slave synchronization, if the main hang, write on the problem. 3.0 will be a good way to help us solve this problem.At present, Redis 3.0 is not stable, if you want to use in the production environment, be cautious.

In what scenarios are cluster file systems applicable, I will summarize them in one sentence. When multiple nodes need to read and write the same file system, they need to use the cluster file system, it can pass the lock information held by the file system to each node. Experiment 1: Create a gfs2 File System Using the disk shared by iSCSI. multiple nodes can be mounted to the same file system to ensure d

Why use a cluster? There are two main reasons: first, for some core systems require long-term non-disruptive services, in order to provide high availability we need a cluster of multiple machines, on the other hand, as the traffic becomes more and more complex business logic, single machine processing capacity is not enough to deal with so many and complex logic, A number of additional machines are required

applications have a limit on the number of CPUs that can be used. The server acts as a separate entity, which is a single point of failure in the solution. If only one server is responsible for passing the functionality of the component within the application, its failure can cause the application to fail. Adding servers increases the complexity of managing and monitoring server hardware and its associated software. Solution SolutionsInstall services or applications on more than on

Introduction The Microsoft Cluster Server (MSC) connects multiple Windows NT-based operating systems to present them to network customers as a single, high-availability system. From the perspective of the system administrator, MSC provides additional management convenience and scalability, And the MSC architecture is scalable for future versions and can be perceived by clusters (cluster-aware) the applic

Distributed Database computing involves distributed transactions, data distribution, and data convergence computing. Distributed Databases can achieve high security, high performance, high availability, and other features. Of course, they also bring high costs (fixed costs and operational costs ), we analyze the design ideas from the implementation of MongoDB and MySQL Cluster to abstract some design methods that we can reference when designing databa
