Previously, we published a simillar list named List of Python Libraries For Data Science & Machine Learning. Just to repeat the same sayings - knowing basics around Python is a need for development around Data Science. We guess, most of the readers already used with installing Jupyter and working with Jupyter. This article is not exclusively related to Jupyter Notebook but is very important … [Read more...]
Fields of Application of Big Data : Part I
The possibilities with regard to the networking on the Internet means that a lot of data exchange takes place between the devices. This exchange includes both structured and unstructured data.

Cloud Infrastructure for Sensitive Workloads
Business-critical applications in sensitive industries are facing hurdles in the cloud. Cloud made the entire IT infrastructures possible to be configured with just a few clicks of the mouse, making the servers are immediately available, and when RAM, storage or computing power is scarce, the infrastructure can be easily readjusted and scaled. Virtual Locations aims to combine the benefits of the … [Read more...]
Edge Computing vs. Cloud Computing
Cloud computing happens in some centralized location with a huge resource in the pay-as-you-go model. Edge computing happens on the device itself. This comparison arises in this era of big data and IoT for different reasons. Edge computing is the data processing power at the edge of a network which is pushing the computing applications, data, and services away from the centralized nodes. A … [Read more...]
How to Install OpenVPN on Cloud Server (Debian 10)
Reading our previous article on OpenVPN may be practical to many of the readers. You need to configure a non-root user with sudo privileges and ideally another server to certificate authority (CA). How to Create Own Certificate Authority (CA) With EasyRSA is a separate guide which is mandatory to read before proceeding with this guide. Also, try to follow our guide on Initial Cloud Server Setup … [Read more...]
How to Create Own Certificate Authority (CA) With EasyRSA
A certificate authority (CA) is who issues the digital certificates. We need this for installation of some software, such as OpenVPN. For doing that, we have to download the latest version of EasyRSA. EasyRSA is the CLI utility to build and manage a PKI CA. A CA acts as a trusted 3rd party. The format of these certificates is specified by the X.509 standard. A certificate signed by a … [Read more...]
Apache Cassandra Versus Apache Phoenix
In our previous discussions, we have compared Apache Cassandra with Apache Hbase and Apache Cassandra with MongoDB. In one of those articles, we already mentioned that Apache Cassandra is more appropriate to compare with Apache Phoenix than Apache HBase. Also, it will make understand why commonly HBase is compared with Apache Cassandra, not Apache Phoenix. Apache Phoenix is a relational … [Read more...]
Apache Cassandra vs Apache HBase
In the last article we have compared Cassandra with MongoDB. That comparison made it obvious that we need to compare Cassandra with HBase, and MongoDB with HBase to complete the understanding. Cassandra and HBase are similar at many things but Cassandra's consistency model is like DynamoDB to provide eventual consistency. HBase is a part of HDFS which runs on top of Hadoop (based on … [Read more...]
MongoDB vs Cassandra : Comparison of NoSQL Databases
Previously we compared DynamoDB and MongoDB. MongoDB vs Cassandra is another frequently compared NoSQL database. Apache Cassandra is fully Free and Open Source Software which provides scalability. MongoDB is developed by MongoDB Inc, it has other options than just the MongoDB Open Source Software we commonly use. Apache Cassandra has scalability, linear performance, distributed architecture, … [Read more...]
What’s the Difference Between Hadoop and Spark?
