The Internet of Things (IoT) has the potential to transform every aspect of a company's operations. However, if the IoT platform is not able to easily interface with existing assets of the enterprise, or requires employees to have new skills, their opportunities will be impacted and attractiveness will be reduced.
Microsoft Azure IoT platform can work as needed. It can easily integrate existing devices and ser
In the micro-service architecture, several basic service governance components are needed, including service registration and discovery, service consumption, load balancing, circuit breakers, intelligent routing, configuration management, etc., which are co-organized by these basic components to form a simple microservices system.

this is not a client-side jump, the browser can not see the address changes, only based on the return information to verify, And can not cross the domain name, only at the current site to jump, in verifying the jump route must also create a simple REST service, as follows: Package Org.lixue.zuul;??Import org.springframework.web.bind.annotation. pathvariable; Import org.springframework.web.bind.annotation. requestmapping; Import Org.springframework.web.bind.annotation.RequestMethod;Import org.
When we configure the gateway to invoke the service of the cluster, the Ribbon route filter is executed, which is encapsulated as a hystrix command to execute when forwarding, and the Hystrix command has fault tolerance if there is a problem with the "source service" (such as a timeout), the The Hystrix command will trigger a fallback, and we need to implement the Org.springframework.cloud.netflix.zuul.filters.route.ZuulFallbackProvider interface, whi
method One:
First locate any other networked computer on the same LAN, and then double-click the Local Internet Protocol (TCP/IP) entry, and fill in the default gateway and subnet mask inside the computer.
Method Two:
1, find the same LAN other normal operation of the computer, click on the Win+r key combination, in the pop-up dialog box directly input cmd, and then click Enter;
2, came to the Msdos interface, will pop up a cut interface,

There's also a lazy approach to max_children,
If your PHP is 5.3, then you can set the FPM style to Apache-like, this time the number of children by FPM automatic control. The corresponding configuration parameters are
Start_servers: Number of start processes
Min_spare_servers: Minimum number of processes
Max_spare_servers: Maximum number of processes
When the server is more idle, FPM will take the initiative to kill some redundant children, to save resources, when the se

Meet a customer, there is a need to extract data from MSSQL into Oracle. After searching the internet, I feel that the Gateway tool can be implemented, so we will set up an experimental environment for testing. First download the corresponding installation package on the Oracle delivery.The experimental environment is as follows:Oracle Database:IP Address: 192.168.56.100Database name: ORCLDatabase Oracle_homOracle accesses MSSQL via
If you want to enter the official website, you should first break through the gateway (GetWay). This is easy to understand, because an intranet must always access the internet through the gateway. As for how to break through the gateway, this is no different from accessing a server that is not a gateway. After breaking
With the rapid development of network technology and information appliances, more and more families require the establishment of a home network. The home gateway is the core of the entire home network. It implements Internet access, remote control, and the function of connecting to a heterogeneous subnet in the home. The home gateway based on the PC solution is not only costly, but also requires that the co
Address: Use 21 bits to identify the network number, 8 bits to identify the host number, the front three bits are "110". The first paragraph of the Class C address has a value between 192~223, the first, second, and third paragraphs together to represent the network number. The last segment identifies the host number on the network. Class C addresses are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts.From the above introduction we know tha
