pull the code pushed by others from the server and learn about its author, time, modification instructions, and specific modifications.
In this way, Version Control provides great convenience for collaborative development. Even if it is developed by one person, it records our entire development history, which is of great help and value.
For example, if a modification or even a problem occurs throughout the sy

Failure Transparency: The user will not notice that a resource (perhaps he has never heard of this resource) is not working properly and that the system subsequently recovers from a failure.
Persistent Transparency: hides the resource in volatile memory or on this disk.
28 detailed analysis of three factors that affect the scalability of a distributed system
The Computer Science Department of the University of Washington has just published a speech by Max Krohn (MIT) entitled "maintaining Web security with distributed information flow control ".
In his speech, Max explained that he had observed a revolution in the computing field, and was switching from desktop software to server-side software and cloud computing.
But he warned:
Web software is pron

Preface
I've been busy with trifles in recent months, and I haven't been idle for nearly a year. Busy in the fall of 2018 years, have to sigh time is always like fleeting, also do not know what harvest and lost what. Recently a little rest, bought two books unrelated to technology, one is Yann Martel wrote "The High mountains
In a distributed system based on SOA architecture, Services (service) become the basic function of providing units, regardless of the business process is not related to the basic functions, or specific business logic, are implemented in the corresponding services. Services to provide a unified interface, the use of standard communication between services to interact, each single service refined and effectiv

The experimental results show that our distributed event correlation mining algorithm has a near-ideal speed improvement compared with the centralized mining method. 1.introductionLarge-scale distributed systems: Cluster systems (CLUSTERSYSTEM), Cloud computing Systems (Cloud computing system)The key to buildi

So, we need to focus on the following scenarios:1) Disaster tolerance : Data not lost, node failover.2) consistency of data : Transaction processing3) Performance: Throughput, response timeAs mentioned earlier, to solve the data is not lost, only through the data redundancy method, even if the data partition, each area also needs data redundancy processing. This is the copy of the data: when the data loss of a node can be read from the copy, the data c

The spring boot framework reduces the use threshold of the spring technology system, simplifies the building and development of spring applications, and provides automatic integration of popular third-party open source techno
the user-space context switches are no longer needed for file system I/O.Because Linux displays a common interface to the file system (via the virtual file system switch [VFS]), Ceph's user perspective is transparent. The perspective of the administrator must be different, considering that many servers contain a potential factor for storage systems (see the Reso

Because Linux displays a public interface of the file system (through the Virtual File System switch [VFS]), the CEpH user perspective is transparent. The Administrator's perspective m

Using Distributed file systems makes it easy to locate and manage shared resources on your network, use a unified naming path to complete access to required resources, provide reliable load balancing, provide redundancy between multiple servers with FRS (File Replication services), and integrate Windows permissions to ensure security.
The process of configuring a Distributed File server is

1. Methods based on a specific replica:
Primary Replica method: Each data object is set to a unique primary replica, generally set in a frequently blocked site, the primary copy of the site is the main site of the data object, different data objects have a different main site. The lock on the data object is managed by the LM (lock man

The administrator's perspective is certainly different, given the potential for many servers to contain the storage system (see the Resources section for more information on creating Ceph clusters). From a user's point of view, they have access to large storage systems without knowing the metadata servers, monitors, and separate object storage devices that are aggregated into a large-capacity s
