Apache fund that distributes massive amounts of data to a large number of inexpensive servers, thus piecing together a single point of failure-free information management cluster. Before Twitter, Facebook and Digg have started using Cassandra, and Cisco WebEx has used Cassandra to collect user feedback. Recently, San Francisco, the new company Clustrix publicly declared that their products are more powerful and excellent, can complete MySQL do bad th
network model by Openvswitch GRE, but this approach is a bit clumsy in large-scale systems. For example, if the system has n hosts and they need to communicate between them, an n (n-1)/2 GRE tunnel is required, although it is possible to prevent the bridge loop by enabling the SPT protocol, but maintaining N (n-1)/2 tunnels is still a lot of work. So next consider how you can automate the implementation.4. References

ProxyProxy is designed to address the external network's ability to access the application services provided across the container in the machine cluster, and from 3-3 the proxy service is also running on each minion. Proxy provides TCP/UDP sockets proxy, each creating a service,proxy mainly from ETCD to obtain services and endpoints configuration information, or can also be obtained from file, Then, based on the configuration information, a proxy process is started on Minion and
receiving the UDP packet. When a TCP connection is established, data streams containing spam characters are sent until the connection is closed. Hacker uses IP spoofing to launch DoS attacks. Forge a UDP packet between two chargen servers. Similarly, the Fraggle DoS attack broadcasts a packet with a spoofed IP address to the port of the target address. The victim is overloaded to respond to the data.Port: 21Service: ftpDescription: The port opened by the FTP server for uploading and downloading
Software as a service (SAAS)ModeAs early as 1990, the concept of software as a service had emerged. SAAS (software as a service) and "On-Demand software" (On-Demand software), The Application Service Provider (Asp, Application Service Provider), and hosted software (managed software) it has a similar meaning and is a mode of providing software through the Internet.
SAAS solution providers were highly sought after by venture capital and peaked in the early 2000 s. With the rapid contraction of v

In the video and teleconference field, the mature solutions currently use cisco or WebEx solutions. However, these commercial solutions are not open-source, the two are relatively closed, and the three are relatively high. Currently, WebRTC-based real-time communication is a mature solution for interactive live broadcasts with a relatively small number of interactions.
It is a real-time communication between multiple parties based on
application development and distribution on the Internet, such as virtual servers and operating systems. This saves your hardware costs and makes collaboration between scattered studios easier.

Code review mechanism is not well done. On the one hand, the team may not be able to buy services for multi-person online conference systems such as WebEx and livemeeting due to time division.
