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…

How to use Pandas Series Method top ideas

I am sharing the ideas on how to use a series constructor on a dataset using Python pandas.
...
 

A series is an object of Pandas that represents a one-dimensional labeled array capable of holding any data type (integers, strings, floating-point numbers, Python objects, etc.).

Example of Dataframe data


Dataframe data


Example of Single Dimension Data

A single dimension data you can derive as (index, value):


 Index Value
 1 10           
 2 40
 3 01
 4 99


So, in the above "Dataframe" when you pull out the data of a single column with its index, you can say it as one-dimensional data.

When one index has multiple values in brackets, you can say it as a multi-dimensional array. The example is (1, (10,20))
mySeries = pd.Series(data, index=index)
Here, pd is a Pandas object, and data refers to a Python dictionary of "ndarray" or even a scalar value.

A Series is a single column of data from a DataFrame. It is a single dimension of data, composed of just an index and the data.

How to get Values and Index using Series Method in Python Pandas

In the first example, I show how to construct single dimension data and how to get index and values from the series data.


>>>mySeries = pd.Series([10,20,30], index=[1,2, 'a'])

In the above example, in the index, I have given 'a'. So for alpha index types, you need to give in quotes.

The result from the above code is you got both values and index.

Hyperledger Fabric: 20 Real Interview Questions

Image
I am practicing Hyperledger. This is one of the top listed blockchains. This architecture follows R3 Corda specifications. Sharing the interview questions with you that I have prepared for my interview.

Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions1). What are Nodes?
In Hyperledger the communication entities are called Nodes.

2). What are the three different types of Nodes?
- Client Node
- Peer Node
- Order Node
The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.

3). What is Channel?
A channel in Hyperledger is the subnet of the main blockchain. You c…

Python IF Statements Multiple Conditions Examples

Image
I shared how to write multiple if conditions (statements) in Python. These are the best examples useful for interviews and projects.
Many programmers confuse how to write IF conditions in Python. The below examples act as a handy guide for beginners and experienced.
Python IF Statements the Best Examples
IF, IFIF 'ELSE'IF 'or'IF 'and'Nested IFIF 'continue'IF 'break'
In Python,  the decision making logic you can write with IF condition. You can write multiple IF conditions (Single way decision). At the same time, you can write IF and ELSE conditions (Two-way decision).
Multiple IF conditions the best example.def main():         celsius = float(input("What is the Celsius temperature? "))         fahrenheit = 9/5 * celsius + 32         print("The temperature is", fahrenheit, "degrees Fahrenheit.")  # Print warnings for extreme temps  if fahrenheit > 90:  print("It's really hot out there. Be careful!")  if fahrenhe…

Best Machine Learning Book for Beginners

Image
You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.
