**3. Conclusion**

In summary, a web server system uses several load balancing techniques for distributing its load among available web resources. These resources are getting costlier day-by-day; therefore, efficient cost optimization mechanisms are required to support by small organization or industry. In this chapter, several load balancing issues have been identified for efficient use of web resources in distributed environment. Detailed description of existing approaches, strength, limitation, and future scope has been analyzed and an adequate radiance has been thrown to these techniques. On the basis of abovementioned issues, several future dimensions have been identified that will be beneficial for the research community to achieve various objectives:
