Introduction to Virtual Linux Server seminar Topic:
The internet has expanded around the world and the internet servers have to fill the huge support like never in the past. The active clients have been grown and equally get in connection with the server at same time. The users and also workload has extremely expanded. The companies are therefore ready to provide the quick solutions and 24 hours availability to their users for the continuous business solutions. The requirements of the systems for their users are highly recommended. This can be provided as mentioned below.
- Scalable: The server has made scalable or measurable to compare the requirement of the users or clients.
- 24 hours available: The server must be available and meet the client’s requirement for 24 hours even it is in some failures.
- Manageable: The system is very distant and large then also it has to be manageable.
- Cost effective: The system should be affordable.
The only server is unable to handle this job. On the other side the update of the server is difficult. The more up gradation of the server shall be more financial concerned. To overcome this group of the server with connection to speed network has come up as an active architecture to construct more measurable and deliver services. The slightly coupled architecture are more measurable, less cost and more dependable as compared with the multi coupled architecture. The various servers dealt with the clients and their requirements in an measurable support. The Linux Virtual Server (LVS)provides the answer to this problem.
The Linux Virtual Server is used as software tools the links the Network connections to the multiple servers which are meant for taking up the workload. The LVS is applied as highly measurable, available and valuable services. The LVS prototypes have been introduced to handle websites of the more workload on the Internet like the Linux portal linux.com, sourceforge.net, UK National JANET Web Cache Services.
The LVS establishes the connections between the Network connections to servers as per the scheduling algorithms by providing the services of the Cluster as a virtual support in a single IP address. The client is able to communicate to all clusters like a single server. The client needs not to be modified. The Scalability also get by combining or replacing the node in the cluster. The high availability is delivered by identifying the node and daemon failures by the system reconfiguration.
