SECURITY AND CACHE MECHANISM IN HADOOP APPLICATION
Keywords:
Performance, algorithms, crucialAbstract
In earlier time traditional tools like SQL Databases, Files etc. were used to handle data and its issues. With increase in the volume of data, traditional tools struggled a lot to store, retrieve manipulate data and hence Hadoop and Big Data evolved. Security and Performance in any application is an issue which needs to be addressed with increasing expectation of immediate availability of data and information. Security poses a major challenge which can be addressed with the help with encryption and decryption mechanisms. The main objective of encryption is to safeguard the confidentiality of data stored on computer or transmitted via Internet or other media. In Modern era encryption algorithms play a crucial role in security assurance of Computer systems andcommunications across network as these algorithms can provide confidentiality, authenticity, data integrity and Non repudiation.Another aspect of today‟s modern application development is that developers have a wide variety of techniques and technologies available to improve application performance and end-user experience. One of the most widely used technologies is the cache mechanism. By using cache at the client side the applications cane greatly benefited by improving response times and reducing server I/O load. One of such examples is HTTP caching techniques which are always associated with the client side cache mechanisms.
