4 Layers of AWS Architecture a Quick Answer

I have collected real interview questions on AWS key architecture components. Those are S3, EC2, SQS, and SimpleDB. AWS is one of the most popular skills in the area of Cloud computing. Many companies are recruiting software developers to work on cloud computing.

AWS Key Architecture Components AWS is the top cloud platform. The knowledge of this helpful to learn other cloud platforms. Below are the questions asked in interviews recently.
What are the components involved in AWS?Amazon S3.With this, one can retrieve the key information which is occupied in creating cloud structural design, and the amount of produced information also can be stored in this component that is the consequence of the key specified.Amazon EC2. Helpful to run a large distributed system on the Hadoop cluster. Automatic parallelization and job scheduling can be achieved by this component.Amazon SQS. This component acts as a mediator between different controllers. Also worn for cushioning requirements those are obt…

4 Top Python Oops Concepts Simplify Your Coding

Oops concepts in Python explained in this post. Python supports Encapsulation, Inheritance, Abstraction, Polymorphism and Dynamic binding. These simplify your coding effort. 

I have given examples on Python Oops ( Object oriented) concepts.

Python Oops (Object oriented) Concepts

  1. Encapsulation
  2. Data hiding and abstraction
  3. Inheritance
  4. Polymorphism (overloading/overriding)
The fifth Python special property is Dynamic binding.



#1 Python Oops Encapsulation

Wrapping of data and functions in a single unit is called Encapsulation.

Encapsulation

#2 Python Oops Data Hiding and abstraction

User program refers methods from an object is called abstraction. Keeping all the methods under one object called data hiding.

Abstraction

#3 Python Oops Inheritance

Inhering properties means, referring property of an Object of a class from an Object of the other Class.

Inheritance

#4 Python Oops Polymorphism

Poly means many. The definition of one function can use for many. 

The best example is the "+" operator. You can use it for the addition of numbers, and concatenate of String. 

Polymorphism

#5 Dynamic Binding

Dynamically you can call one procedure during the execution of the main program is called Dynamic binding. 

Dynamic Binding
