Step-by-Step Guide to Creating an AWS RDS Database Instance

Image
 Amazon Relational Database Service (AWS RDS) makes it easy to set up, operate, and scale a relational database in the cloud. Instead of managing servers, patching OS, and handling backups manually, AWS RDS takes care of the heavy lifting so you can focus on building applications and data pipelines. In this blog, we’ll walk through how to create an AWS RDS instance , key configuration choices, and best practices you should follow in real-world projects. What is AWS RDS? AWS RDS is a managed database service that supports popular relational engines such as: Amazon Aurora (MySQL / PostgreSQL compatible) MySQL PostgreSQL MariaDB Oracle SQL Server With RDS, AWS manages: Database provisioning Automated backups Software patching High availability (Multi-AZ) Monitoring and scaling Prerequisites Before creating an RDS instance, make sure you have: An active AWS account Proper IAM permissions (RDS, EC2, VPC) A basic understanding of: ...

The Quick and Easy Way to Analyze Numpy Arrays

The quickest and easiest way to analyze NumPy arrays is by using the numpy.array() method. This method allows you to quickly and easily analyze the values contained in a numpy array. This method can also be used to find the sum, mean, standard deviation, max, min, and other useful analysis of the value contained within a numpy array.


NumPy Python

Sum

You can find the sum of Numpy arrays using the np.sum() function. 
For example: 

import numpy as np 
a = np.array([1,2,3,4,5]) 
b = np.array([6,7,8,9,10]) 
result = np.sum([a,b]) 
print(result) 
# Output will be 55


Mean


You can find the mean of a Numpy array using the np.mean() function. This function takes in an array as an argument and returns the mean of all the values in the array. 

For example, the mean of a Numpy array of [1,2,3,4,5] would be 
result = np.mean([1,2,3,4,5]) 
print(result) 

#Output: 3.0


Standard Deviation


To find the standard deviation of a Numpy array, you can use the NumPy std() function. This function takes in an array as a parameter and returns the standard deviation of that given array. 
For example: 
import numpy as np 

arr = np.array([1, 2, 3, 4, 5]) 
std_dev = np.std(arr) 
print(std_dev) 

# Output: 1.5811388300841898

Max


To find the max Numpy Array, you can use the max() function from the Numpy library. 
For example, to find the max value in an array of numbers: 

import numpy as np 
arr = np.array([1, 3, 4, 6, 10]) 
print(np.max(arr)) 
This would output 10, which is the max value of the array.


Min


The easiest way to find the minimum value of a Numpy array is with the np.min() function. This function takes in a Numpy array and returns the minimum value in the array. 

Example: 
import numpy as np 
a = np.array([1, 5, 10, 100, 200]) 
min_val = np.min(a)
 print(min_val) 
# Output: 1
