Role of Turbolinux in IDC

The role of Turbolinux in IDC-Linux Enterprise Application-Linux server application information. The following is a detailed description. IDC has gradually become the basis of all large-scale ISP core services. Compared with traditional ISP access services, ISP needs to build on the basis of infrastructure and services, provide services to icp asp or enterprise through host hosting or suspended hosts
Higher-level enhancement services
The construction of IDC involves a wide range of contents. Its physical infrastructure services include the construction of backbone networks with high capacity.
High-quality data center construction supports RACK services with small space and high scalability and availability
Hardware Selection LAN device selection and construction and many other aspects
Another important aspect of IDC is to provide customers with value-added solutions, including high selection and support.

Software enhancement solutions provided by IDC
Backend data center and database cluster Solution
Multiple services of IDC are built on the basis of databases, which facilitates the provision of advanced information content management
For the most effective information storage management and sharing, selecting an operating system dedicated to database optimization will undoubtedly
Enhance the quality of the entire IDC service
Turbolinux TDS Server is a high-performance network operating system platform developed for database applications.
The goal is to provide a high-performance and high-stability operating system platform system for the database platform.
The Optimization of the core system is specially customized. the settings of all core parameters are based on running data.
The shared memory and asynchronous I/O, which are closely related to the database system, are specially optimized here.
Applications that build databases on the platform can obtain extraordinary performance. TDS is fully bundled with Oracle 8I and
DB2 makes database installation the best effort to bind the operating system with the database, and the low layout cost exceeds
Imagine and precisely cooperate to improve the performance of the entire system
Database Server is one of the most critical systems in IDC. To ensure the availability and security of database services
Discuss the solution for using database clusters. Use TurboHA dual-host based on Turbolinux.
Wrong system this solution ensures that data is not lost and can improve the high availability of the system so that the database system does not stop
Working TurboHA enables online fault tolerance through dual-machine Hot Backup System software installed on two servers
Capability means another service that is waiting for monitoring when a working server cannot work normally.
Server quickly takes over the business programs and data on Abnormal servers to make business transactions of network users run normally
Ensures the integrity and consistency of transaction data and the high reliability of transaction services.
TurboHA uses a solution combining Fault-Tolerant Software and disk arrays. It has the automatic error correction function TurboHA.
For Linux can manage two Linux servers and provide two working modes of Dual-machine Hot Backup
When a work machine fails, the backup machine automatically takes over the work machine's tasks and data so that users' business transactions are normal.
Regular Operation customers do not need to interrupt their network applications to reduce the losses caused by host shutdown.
The two servers run different application tasks and act as backup servers.
When the host goes down, another host can quickly take over the faulty host.
The dual-server used by TurboHA adopts the TCP/IP network protocol and the user connects to the dual-server backend for the customer-service
Network user transparent system has the features of openness, reliability, stability, high performance, and high scalability.
Website load balancing Solution
Server Load balancer is a technology used to improve the performance of website systems and enhance the functions of IDC. Currently, there are multiple methods to implement Server Load balancer.
Server Load balancer uses the round-robin DNS solution, which is the simplest and most intuitive solution.
While the average traffic distribution is not able to process the request service of the address, it also lacks the effective location for the faulty node.
The Hardware Solution for Server Load balancer mainly uses the NAT network address translation function.
Hardware of high-end routers or vswitches for load balancing is not easy to expand and maintain.
It is expensive to upgrade the hardware solution. At the same time, it can only perform node-level status checks and cannot be refined
Service-level processing: The NAT mechanism is used to manage nodes in clusters, which requires a lot of work.
It is easy to become the bottleneck of the entire system because of a single fault point, so the availability is poor, negotiated Processing
The disadvantage of the solution is that there is no significant management node in the entire cluster and all nodes are determined by the entire working node.
It is difficult to conduct heavy network installation and maintenance through mutual negotiation.
The most effective method for website load balancing is to use the traffic distribution mechanism to implement a direct routing IP tunnel.
And Network Address Translation three methods TurboCluster Server supports all these three operations due to their
Advanced structure and technology: The TurboCluster Server won the most
Excellent WEB solution Awards
As a solution for high availability and load balancing, The TurboCluster Server can operate a variety of heterogeneous clusters.
As a system platform, such as the complex network that uses unix linux nt to provide services, the Service nodes can be different.
And the service can be delivered to the nearest server according to the region of the requesting user.
TurboCluster supports all TCP/IP-based applications. It not only effectively handles faulty nodes

Better detection service capability, effectively improving Load Balancing Capability
TurboCluster Server is easy to install and maintain at a low cost. It has a dedicated file system.
The system synchronization tool can easily synchronize or copy files and file system TurboCluster
With high scalability, service nodes are not limited to Management Nodes consisting of multiple nodes, which constitute a highly available
Solution TurboCluster is the best load balancing solution for IDC
Cache Server

On Turbolinux, there are multiple caching servers with the most stable and advanced algorithms. SQUID
SQUID can effectively and transparently copy Web files and automatically route HTTP requests to the Proxy Server and
Download a node or a set of URLs from the files returned by the Cache to ensure the speed of the busiest nodes.
Memory and availability can automatically refresh the cache and reject files protected by Access Control in the cache.
SSL-encapsulated file access control allows and limits access to specified external resources.
The Group IP address specified by the verified user name/password-DNS-and the host-based wildcard expression are implemented.
Supports SNMP for secure remote cross-platform management using HTML Format
Remote Monitoring and Management high-performance HTTP engines provide maximum throughput and high scalability.
The effective cache space of the storage system can process tens of millions of URLs to register all http ftp and
Gopher transactions include user agents in specified regions and Transaction completion statuses. Fault Tolerance is supported.
In short, IDC is a very important and very high-end application in the Internet.
It plays a key role in providing a powerful system-based guarantee for IDC operation.
