Cloud Computing Middleware an approach- Virtualization

Cloud+Virtualization+Jobs, Career
In order to run applications on a Cloud, one needs a flexible middleware that eases the development and the deployment process.

GridGain provides a middleware that aims to develop and run applications on both public and private Clouds without any changes in the application code.

It is also possible to write dedicated applications based on the map/reduce programming model. Although GridGain provides mechanism to seamlessly deploy applications on a grid or a Cloud, it does not support the deployment of the infrastructure itself. It does, however, provide protocols to discover running GridGain nodes and organize them into topologies (Local Grid, Global Grid, etc.) to run applications on only a subset of all nodes.

Elastic Grid infrastructure provides dynamic allocation, deployment, and management of Java applications through the Cloud. It also offers a Cloud virtualization layer that abstracts specific Cloud computing provider technology to isolate applications from specific implementations

Virtualization in CLOUD

With rapid expansion of Information Technology (IT) infrastructures in recently years, managing computing resources in enterprise environments has become increasingly complex. 

In this context, virtualization technologies have been widely adopted by the industry as a means to enable efficient resource allocation and management, in order to reduce operational costs while improving application performance and reliability. 

Generally speaking, virtualization aims at partitioning physical resources into logical resources that can be allocated to applications in a flexible manner. 

For instance, server virtualization is a technology that partitions the physical machine into multiple Virtual Machines (VMs), each capable of running applications just like a physical machine. By separating logical resources from the underlying physical resources, server virtualization enables flexible assignment of workloads to physical machines. 

This not only allows workload running on multiple virtual machines to be consolidated on a single physical machine, but also enables a technique called VM migration, which is the process of dynamically moving a virtual machine from one physical machine to another.

Four Tableau products a quick review and explanation

I want to share you what are the Products most popular.

Total four products. Read the details below.

Tableau desktop-(Business analytics anyone can use) - Tableau  Desktop  is  based  on  breakthrough technology  from  Stanford  University  that  lets  you drag & drop to analyze data. You can connect to  data in a few clicks, then visualize and create interactive dashboards with a few more.

We’ve done years of research to build a system that supports people’s natural  ability  to  think visually. Shift fluidly between views, following your natural train of thought. You’re not stuck in wizards or bogged down writing scripts. You just create beautiful, rich data visualizations.  It's so easy to use that any Excel user can learn it. Get more results for less effort. And it’s 10 –100x faster than existing solutions.

The Sqoop in Hadoop story to process structural data

Why Sqoop you need while working on Hadoop-The Sqoop and its primary reason is to import data from structural data sources such as Oracle/DB2 into HDFS(also called Hadoop file system).
To our readers, I have collected a good video from Edureka which helps you to understand the functionality of Sqoop.

The comparison between Sqoop and Flume

The Sqoop the word came from SQL+Hadoop Sqoop word came from SQL+HADOOP=SQOOP. And Sqoop is a data transfer tool. The main use of Sqoop is to import and export the large amount of data from RDBMS to HDFS and vice versa. List of basic Sqoop commands Codegen- It helps to generate code to interact with database records.Create-hive-table- It helps to Import a table definition into a hiveEval- It helps to evaluateSQL statement and display the resultsExport-It helps to export an HDFS directory into a database tableHelp- It helps to list the available commandsImport- It helps to import a table from a database to HDFSImport-all-tables- It helps to import tables …

Different Types Of Payment Cards

The Credit Card (Shopping): The purpose o this card is to buy any item withing the limit prescribed by banks to cardholder. These cards can have both Magnetic stripe and Chip cards. 
Now a days all banks are issuing credit cards with CHIP and PIN. After entering the PIN by cardholder, then transaction starts for further processing.

The debit (ATM, Cash) card is a relatively new method of payment. It is different from a credit card because the debit cardholder pays with the money available in their bank account, which is debited immediately in real time. A debit card seems to be more dangerous compared to a credit card because the debit card is directly linked to the bank checking account and usually allows ATM cash withdrawals.

On the other hand, it is more protected by the required two-factor authentication (PIN number plus card itself). The real dangerous element of many branded debit cards is that they can be processed as credit cards, without entering the PIN.
