30 High Paying IT Jobs

Cloudera is a company that makes a commercial version of Hadoop. Although Hadoop is a free and open-source-project for storing large amounts of data on inexpensive computer servers, the free version of Hadoop is not easy to use. Several companies have created friendlier versions of Hadoop, and Cloudera is arguably the most popular one.

Service-oriented architecture or SOA or is actually an old term for a software concept that's growing increasingly popular, thanks to cloud computing. Practitioners of it write their code in small bites, making little "services" that can be shared among multiple apps. Instead of every cloud app needing its own way of dealing with passwords, for instance, a "password service" can be shared by many.
SOA+jobs

8 Popular Encryption methods real Usage

Encryption works as it replaces original data with some special characters and stores the data. You need a private key to decrypt the data. Else it is not possible to understand encrypted data even for hackers.

Private keys are two types. Sender uses one private key and receiver uses one other private key.
I have given in this post about 8 encryption methods.
