We CNT Technologies is starting a series of blogs on AWS. Whether you are

looking to learn about cloud computing for your career or for interesting purposes.

we are sure that you will find this article helpful 

Let us Begin with cloud computing 

AWS:

 AWS server is a secured cloud service provided by amazon for offering computing power,

database storage, content delivery, and other functionality to help business growth.

Amazon Web Services is a secured cloud services platform,which offer his computing power

,storage for database, content delivery, and other functionality to help businesses to

grow and scale.

  AWS cloud server allow you to do following things

• AWS allow you to Run web and application servers in the cloud .To host dynamic websites.
• AWS store  securely all your files on the cloud. So you can access them from anywhere.
• AWS cloud alllow you to Use managed databases like mysql, postgresql, Oracle or sql
• Server to store information.
•  Deliver static and dynamic files quickly around the world using a CDN
•  Send bulk emails to your customers.
•  Now that you know what you can do with AWS, let's have an view of various AWS services.

 Terminologies used in AWS

 Region —

A region is geographical area which two or more zones.

 Availability Zone —

it is a data center.

 Edge Location —

These are cdn endpoints for cloud front.

 EC2 —

These are only just the virtual machine which is running on

cloud.you have os level control on virtual machines. you can run any

services as you want on virtual machines.

 LightSail —

If you do not have any prior experience with AWS then this service is

for you. It automatically deploys and manages to compute, storage and networking

capabilities required to run your applications.

 ECS —

It is a highly expendable container service to allow you to run the Docker containers in

the cloud.

 EKS —

Allows you to use kubernete on AWS cloud without installing and managing your own

Kubernete control plane. It is a relatively new service.

 Lambda —

AWS’s server less technology allows you to run functions in the cloud servers. It’s a

high cost saver as you pay only when your functions are executing.

 Batch —

It enable you to easily and efficiently run batch computing loads of any scale

on AWS cloud using amazon Ec2 and Ec2 spot fleet.

 Elastic Beanstalk —

Allows automated deployment and provisioning of resources like

a highly scalable production website.

 S3 —

storage service of AWS in which we can store objects

like files, folders, images, documents, songs, etc. It cannot be used to install software,

games or Operating systems.

 EFS —

Provides file storage for use with your Ec2 instances. It uses the NFSv4 protocol

and can be bemused concurrently by thousands of instances.

 Glacier —

It is very cost effective to store data for a long term as compare to other

cloud services.

 Storage Gateway —

It is a virtual machine that you install on your on-premise servers.

Your on-premise data can be backed up to AWS providing more durability.

 RDS —

Allows you to run relational databases like

MySqL, MariaDB, PostgreSQL, Oracle or SQL Server. These databases are fully

managed by AWS like installing antivirus and patches.

 DynamoDB —

It is a highly scalable, high-performance NoSQL database. It provides

single-digit millisecond latency at any scale.

 Elasticache —

It is a way of caching data inside the cloud server. It can be used to take

a load off of your database by caching the most frequent queries.

 Neptune —

It has been launched recently. It is a fast, reliable and scalable graph database

service.

 RedShift —

It is AWS’s data warehousing solution that can be used to run complex

OLAP queries.

 SMS —

It allows you to migrate on-site servers to AWS easily and quickly.

Python Programme for generating 12 digit strong password

 

Cyber crime is increasing day by day. weak password  is not good for devices which

demands high confidentiality, privacy and security of user credentials. It is true

that people find it difficult make a secure password which is strong enough to prevent

cyber criminals to grab it.

In this article we will show how to create strong password consisting  numbers,

special-character, upper case, lower case char. which was unpredictable  for

crackers can’t be memorised easily.

In this article we show you to  make python programme for generating a secure password.

The component that are used in password creation programme are:

Random Module:

Random module is used for generating random number in in python language, with

the help of random module we can generate random number and character in a programme

when we need it.

Array:

Random method is used to select at least one character from each arrays.

Programme:1 

programme2:

In this programme we use random method to select at least one character from

each array of characters. In this code we take 3 arrays consisting of uppercase

and lowercase character and 3rd one with special characters. Then combined

all characters array to form a single array. After that uses the random method

to select at least one character from all three arrays. Now that we are sure that 

we have at least one character from each array. Then traverse the password into

array and shuffle b/w characters to prevent it from having a consistent pattern.

if it is consistent then beginning of password is predictable.

Traverse the password  array and append the characters to form a strong password.
