Cloud computing basic Terminology for learners

AWS
The organizational unit of Amazon that provides a variety of cloud services. AWS operates from 11 physical locations across North and South America, Europe, Asia, and Australia.

Content delivery network (CDN)

A distributed system consisting of servers in discrete physical locations, configured in a way that clients can access the server closest to them on the network, thereby improving speeds.

Cloud

A metaphor for a global network, first used in reference to the telephone network and now commonly used to represent the internet.

Cloud portability

The ability to move applications and data from one cloud provider to another. See also Vendor lock-in.

Cloud provider

A company that provides cloud-based platform, infrastructure, application, or storage services to other organizations and/or individuals, usually for a fee.

Cloudsourcing

Replacing traditional IT operations with lower-cost, outsourced cloud services.

Cloud storage

A service that allows customers to save data by transferring it over the internet or another network to an offsite storage system maintained by a third party.

Cloudware

Software that enables creating, deploying, running, or managing applications in the cloud.

Cluster

A group of linked computers that work together as if they were a single computer, for high availability and/or load balancing.

Consumer cloud

Cloud computing offerings targeted toward individuals for personal use, such as Dropbox or iCloud.

Consumption-based pricing model

A pricing model whereby the service provider charges its customers based on the amount of the service the customer consumes, rather than a time-based fee. For example, a cloud storage provider might charge per gigabyte of information stored. See also Subscription-based pricing model.

Content Management Interoperability Services (CMIS)

An open standard for controlling content and document management systems and repositories using web protocols.

Customer self-service

A feature that allows customers to provision, manage, and terminate services themselves, without involving the service provider, via a web interface or programmatic calls to service APIs.

Disruptive technology

A business term that describes innovations that improve products or services in unexpected ways. These innovations change the methods used to accomplish a task, and re-shape the market for that task. Cloud computing is considered a disruptive technology because of its elasticity, flexible pricing models, and maintenance cost compared to traditional IT service provisioning.

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.

The best 5 differences of AWS EMR and Hadoop

With Amazon Elastic MapReduce (Amazon EMR) you can analyze and process vast amounts of data. It does this by distributing the computational work across a cluster of virtual servers running in the Amazon cloud. The cluster is managed using an open-source framework called Hadoop.

Amazon EMR has made enhancements to Hadoop and other open-source applications to work seamlessly with AWS. For example, Hadoop clusters running on Amazon EMR use EC2 instances as virtual Linux servers for the master and slave nodes, Amazon S3 for bulk storage of input and output data, and CloudWatch to monitor cluster performance and raise alarms.

You can also move data into and out of DynamoDB using Amazon EMR and Hive. All of this is orchestrated by Amazon EMR control software that launches and manages the Hadoop cluster. This process is called an Amazon EMR cluster.
