Piolink Server load Balancing solution design

piolink Server load Balancing solution designBasic principles of system design

L practical, advanced, safe and extensible is the basic principle of the system design

This recommendation is first to meet the application requirements for existing and foreseeable future years, and secondly to consider the choice of equipment and systems that currently offer the most advanced technology, with little investment added, and finally to consider the ability of the security system to realize long-term development in the face of application.

L Stability and Reliability

The network system of the underlying transmission platform of the business system must ensure the reliability and stability of its work, guarantee the uninterrupted operation of the year, so as to provide timely, accurate and reliable information support.

L Security

Security is a priority problem that must be addressed in the construction of information systems, or it may have serious consequences that cannot be predicted. Computer system has a breach of a point can make the whole system exposure particularity, so a complete security system needs from the network, host, operating system, application software to the underlying hardware platform for a complete security design, so as to provide multi-level, multi-angle network security guarantee.

L the advanced nature of technology

Technology should be quite advanced, the performance should be able to adapt to the rapid development of network applications, must ensure a broad adaptability to a variety of services have the best transmission efficiency of the network platform, so that the upper-level applications can run smoothly.

L very good system openness and upgrade expansion capability

The network should have excellent openness and the ability to upgrade, support multi-protocol, multi-interface and open structure, easy to external interconnection, to the future application and development of information system to leave ample room for expansion.

L easy to maintain, easy to manage

Network maintainability and manageability is the key factor to ensure the long-term stable operation of the network, easy to maintain easy to manage the network can not only save users a lot of time, energy and operating costs, or the above mentioned a variety of network reliability, security, advanced, extensibility and other characteristics to fully play a strong guarantee.

L practicality

Not only consider saving investment, but also ensure the advanced and usability of the product. When it comes to the interoperability of old devices and the smooth transition of business, users can also get maximum investment protection while achieving the latest outstanding network features. To make full use of existing network resources and communication resources.

System Solution DesignBypass Deployment ModeSolution topology Diagram

The advantage of a bypass deployment is that it keeps the user's existing network environment intact, and when the device is on-line and deployed, it has virtually no impact on the current network's business. For Piolink load balancing devices pas-k a topology with bypass deployment.

Solution Description

As shown, our entire network is built as follows:

1. for a network that grows every day, the number of internal servers grows very fast, in order to be able to smoothly and stably extend the internal network, and increase the server cluster, we in the Data center server Group Bypass Unit piolink pas-k Load Balancing equipment, Piolink Company's Pas-k uses proprietary technology MPA (multi-proxy Architecture ) , strong performance, and high reliability, combined with piolink PLOS Dedicated operating system, the user can choose according to their own needs pas-k a variety of additional value-added functions, strong extensibility.

2. set the SLB server load balancer on pas-k, and pas-k will load balance the servers against the internal server farms. By setting the SLB capability, we can balance the server traffic inside external access to the host of the corresponding server cluster, so that the application Exchange guarantees the best service . According to the customer's application environment, PAS-K will assign the access request to the fastest response server according to the optimal algorithm, guarantee the users to quickly and uninterrupted access to the application in real-time, while pas-k can smoothly and stably extend the internal network, and increase the server cluster, when the data center wants to increase the server later, Simply add the server IP on the pas-k to complete the operation.

3. Configure the server Health Check feature on PAS-K devices to ensure availability of data center application systems. Health checks include multiple detection methods, such as ICMP, DNS, HTTP page detection, and more. When Pas-k detects that a server is not available, the user request is automatically forwarded to the currently functioning server, ensuring uninterrupted user access.

4.in theIntelligent Optimization and acceleration are enabled on the PAS-K, using standard protocols to intelligently compress user-accessed HTTP traffic,withHouseholdsprovides very high communicationQualityvolume of the samewhen,stillcan beStrong Enoughbig.Save the netStation MutualNetworkingAccessBandwidthconsumption, maximize the increaseNetworkwithUser AccessServerinsidecapacity of the speeddegree;pas-kSeriesProductionProduct Energyenoughin theinsidein-store tonumberaccording to the form of the packageCache LiveNetStationpageall the faces can beCache live.insideand the content. whenwithUser Access PleaseAskHairsent topas-kwhen, ifin the cacheinsideEnergy Capacityenoughmatch withHouseholdsof theAccess PleaseAskthedirectly bypas-kto respondwithHouseholdsof theAccess,fromand avoid thetheBackstage ServiceServicesDevice'sLoad PressureForce, while increasing the user's access speed, while the SSL offload function can significantly reduce the burden on the server, improve the efficiency and reliability of the server.

5. PAS-K devices Support network security, QoS bandwidth management and other additional functions, for internal user groups and server groups, the Pas-k can be enabled by the Security Defense module to become a security hub between the outside and intranet areas, so as to protect the intranet more securely; QoS Bandwidth Management Traffic can be graded according to source and destination IP addresses or address groups, applications, ports, content /url , and cookies .

Scenario Implementation features

by pas -k SLB Server load Balancing function, pas -k can be intelligent server load balancing on the internal server cluster, when the client accesses, PAS-K will intercept the traffic that needs to be load balanced, through the set load balancing policy, the traffic will be intelligently allocated to the back end of each real server, so that the application can be exchanged for best service Guarantee.

through Pas-k's powerful Traffic Intelligence optimization and acceleration function, pas-k can use compression, caching and SSL offload technology for client access back-end server farm to optimize processing to save user bandwidth, reduce network delay, and reduce the burden of server. maximize the increase Network with User Access Server inside speed of the capacity .

Through the Pas-k Security Defense module and the QoS bandwidth management function, not only can add a security guard door to the intranet area, so as to ensure the security of the Network data center, ensure the service quality, guarantee the high performance of the key application, and can differentiate the traffic type according to the specific parameters. and determine how the traffic types are handled appropriately to efficiently manage the internal users.
