AWS EC2 Real Story on Elastic Cloud Computing

The short name for Amazon Elastic Computing Cloud is EC2. You can keep this point as an interview question. The computing capacity has an elastic property. Based on your requirement you can increase or decrease computing power.
You need to be very attentive when you enable Auto scaling feature. It is a responsibility on Admins. Amazon AWS EC2Making your existing hardware to the requirement, always is not so easy. So the EC2 feature in AWS helps you to allocate computing power according to your needs. AWS EC2 instance acts as your physical server.It has memory.You can increase the instance size in terms of CPU, Memory, Storage and GPU.EC2 auto scaling is a property, where it automatically increase your computing power. List of Top Security Features in EC2  1#. Virtual Private CloudThe responsibility of Virtual Private Cloud, is to safeguard each instance separately. That means, you cannot access others instance, which is already created by other organization.

Latest Trends in Data Analytics - Speed of NOSQL

Traditional database theory dictates that you design the data set before entering any data. A data lake, also called an enterprise data lake or enterprise data hub, turns that model on its head, says Chris Curran, principal and chief technologist in PricewaterhouseCoopers’ U.S. advisory practice. “It says we’ll take these data sources and dump them all into a big Hadoop repository, and we won’t try to design a data model beforehand,” he says. Instead, it provides tools for people to analyze the data, along with a high-level definition of what data exists in the lake. “People build the views into the data as they go along.

It’s a very incremental, organic model for building a large-scale database,” Curran says. On the downside, the people who use it must be highly skilled
Speed of NOSQL
Alternatives to traditional SQL-based relational databases, called NoSQL (short for “Not Only SQL”) databases, are rapidly gaining popularity as tools for use in specific kinds of analytic applications, and that momentum will continue to grow, says Curran.

Python Syntax Rules Eliminate Errors Before you start debugging

In Python, if you know syntax rules, you can eliminate errors. The basic mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Python is case sensitive. So using the wrong identifier gives an error.
Indentation is unique to Python. You cannot find this kind of rule in any other programming languages Python Syntax Cheat Sheet These are the main areas you need to focus while writing a Python program. You need to learn rules. Else you need to waste a lot of time fixing the issues or errors.
Indentation or Syntax ErrorsExceptionsHandling Exceptions
1. Indentation If you do not follow proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that.

In if loop, the if, elif, and else should have same indentation. Not only, the statement inside of them should have same indentation.Understand these examples a good material on indentation for you.   2. Exceptions  Python raises exception, wh…

Python Improved Logic Easy Way to Calculate Factorial

I am practicing Python programming. This post is you can write logic to calculate factorial in function. This function you can call it a user-defined function. The function name is 'factorial.py'. In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need. Factorial calculation program for supplied input value. Factorial Logic in Python I have completed this logic in 3 steps. Write factorial.pyImportExecute it Write Factorial.py  Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command Use, :wq to come out of the module. Import Factorial.py Go to Python console, using 'python' command. Use import factorial.py command.


Execute Factorial.py  >>> factorial.fact(5) It will show the result of factorial. Bottom line  Factorial o…

Calculate Circle Area the Logic You Need to write in Python

In Python, you can calculate circle area easily by using function. The purpose of Python is to use in data analysis.


You need this logic in many areas. You can use in your present finance projects or new ones.

Benefits of function you can re-use the same code number of times Area of Circle=pi*r*r Area of Circle Steps Given - You Can do Using Two Methods, Explained Both Methods I have given steps to calculate area of circle using two different methods. First I followed by creating an user defined function. Next directly I ran  the formula in interpreter.


Method-1 Steps I have followed to Calculate Area Using FunctionLogged into Cent Os (Linux) Create .py module Import .py module into Python Execute .py module  1. Log in I have first logged into CentOS. You can see there '$'.

2. Creating .py module To create .py module. You can use vi editor command.

You need 'import decimal' to get Decimal values. Else you will get only integer.

Top 10 SCALA Quiz Questions for Programmers

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do.


To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them. There’s a REPL and IDE worksheets for quick feedback.

Developers like it so much that Scala won the ScriptBowl contest at the 2012 JavaOne conference. At the same time, Scala is the preferred workhorse language for many mission critical server systems. The generated code is on a par with Java’s and its precise typing means that many problems are caught at compile-time rather than after deployment.


At the root, the language’s scalability is the result of a careful integration of object-oriented and functional language concepts.(Ref-what is Scala).View Su…
