Route 53

Sachin — Mon, 27 Oct 2025 06:14:18 +0000

it is amazon service it provided the Domain name service because i can not remember the ip address so we provide the name this name attatched to the ip address

ip address used by computer identified the server

Two type of ip

ipv4
ipv6

Some top level domain
.com .in. au
secondary domain level
.gov.in

In a aws route 32 have advantage generally we have webserver and we connected the loadbalancer in the availbility zone
if availablity zone some issue arise load balancer transfer another avialiablity zone

Problem is when the region aries the issue hence we solved the problem help of Route 53

Routing policy of Route53

Simple Routing policy

Weighted Routing policy

Latency Routing policy

FailOver Routing Policy

Geolocation Routing policy

Versioning in S3

Sachin — Sun, 26 Oct 2025 05:22:36 +0000

We can understand the create the bucket and upload the object and access the object

What is versioning in s3

it is the process of restoreation

Replicated the object(restore the deleted the object and file)
Version
i gave simple example of version if you have text file if you write hello and saved the file this is called version 1, and edit the file add some content like hello good morning this is called version 1.2 this is called the version

How to enable the version in s3

Go inside the bucket

select the properties
edit the version of inside the property

select the enable and save changed

How to recover the object

Now we upload the file and deleted the file

Now switch on the version

when we switch on the version

you can see that actual object inside the deleted marker the deleted marker is wall kind of thing behind that object inside when we deleted the object whenever the we enable the version it is not deleted it is actually behind the deleted marker
you can object back you need to deleted the deleted the deleted marker

we deleted the delete marker and disable the version
we replicated the object

Version in s3

we create txt file name demo.txt inside in heloo

upload the bucket this file

add more content the the demo file again upload

see that

when we upload same file two time it save as version

this is version 1

this is version 2

In last create bucket

S3 aws guide

Sachin — Sat, 25 Oct 2025 06:06:12 +0000

What is Amazon S3?

Amazon Simple Storage Service (S3) is a scalable object storage service provided by AWS. It allows users to store and retrieve any amount of data, such as text files, images, videos, and other objects, from anywhere on the web. S3 is designed for durability, scalability, and accessibility, making it ideal for a wide range of use cases, including backups, media hosting, and data lakes.

S3 stores data as objects within buckets. A bucket is a container for objects, and each object consists of data, a key (name), and metadata. Objects can be text files, MP3s, images, or any other file type.

Storage Types

S3 stores data primarily as objects, but it can also support use cases involving:

Object Storage: Stores files like text, MP3s, images, and other data types as objects in buckets.
Block Storage: While S3 itself is object storage, it can integrate with services like Amazon Elastic Block Store (EBS) for operating system-level block storage needs. For example, objects in S3 can store virtual machine images or backups that include OS data.

S3 provides unlimited storage capacity, allowing users to scale storage needs without constraints. Amazon guarantees 99.999999999% (11 nines) durability, ensuring data is not lost, and offers high availability for accessing data.

S3 Storage Classes

AWS S3 offers several storage classes to optimize cost, performance, and accessibility based on user needs:

S3 Standard: Designed for frequently accessed data with low latency and high throughput. Ideal for active workloads like websites and analytics.
S3 Intelligent-Tiering: Automatically moves data between frequent and infrequent access tiers based on usage patterns, optimizing costs without manual intervention.
S3 Standard-Infrequent Access (S3 Standard-IA): For data accessed less frequently but requiring immediate access when needed, such as backups or long-term storage.
S3 One Zone-Infrequent Access (S3 One Zone-IA): Similar to S3 Standard-IA but stores data in a single Availability Zone, offering lower costs with slightly reduced resilience.
S3 Glacier: For archival data with retrieval times ranging from minutes to hours, suitable for long-term storage at a lower cost.
S3 Glacier Deep Archive: The lowest-cost storage class for rarely accessed data, with retrieval times of 12–48 hours, ideal for compliance or archival needs.

Each class balances cost, durability, and retrieval speed to suit different use cases.

S3 Transfer Acceleration

S3 Transfer Acceleration enables fast and secure file transfers over long distances between end users and an S3 bucket. It leverages Amazon CloudFront’s globally distributed edge locations to optimize data transfer.

How It Works

When data is uploaded to an S3 bucket with Transfer Acceleration enabled, it is sent to the nearest CloudFront edge location.
From the edge location, data is routed to the S3 bucket over an optimized network path, reducing latency and improving transfer speeds.
This is particularly useful for users uploading or downloading large files, such as media or backups, from distant geographic locations.

To enable Transfer Acceleration, you can configure it on a bucket via the AWS Management Console or SDK, and use a special endpoint (e.g., <bucket-name>.s3-accelerate.amazonaws.com).

Linux File guide

Sachin — Fri, 24 Oct 2025 15:38:51 +0000

In a linux have 4 ways to create a file

Window and linux guide

Sachin — Fri, 24 Oct 2025 14:38:03 +0000

we discuss the different between the window and user

window

In a window user interact the shell and the shell interact the operating system and operating system interact hardware and also you can see the picture an hardware response the req the the os and os to shell and shell show the output
Note : In a window user interact have two ways
1 Gui (graphical user interface )
example you add a file in window using help of gui
2 Command line
using shell command line

linux

In a linux user have not choice they interact the only the shell and shell interact the kernal and kernal interact the hardware and also hardware response the kernal and shell

Differnce between window and linux

In window have adminstration
In linux have root user
In window have software
In linux have package
In window have os
In linux have kernal
In window have folder
In linux have directory
In window have c drive
In a linux have top level root directory

Window File structure Heiarchy

1 Program file
it contained the software file
2 user file
it is the house of user they login
3 window file
it contain the os related file
4 Program file
it contain the install software file

Linux file system Heiarchy

it it is top level directory it denoted the backslash /

it have

root dir it contain the root user if the root user gave login the linux 2 home it us house of other user if root user created the other user to access the system 3 boot it contain the package related file when the system start the you can see some package start automatic the process called the booting process it contain booting files

4 config
it cofiguration of system user and package

5 usr
it contain file the package user install

6 bin
it contain the registered command example when we type the dir it show dirr of system it registered the bin it can all run by all user
7 sbin
it a special command run by root user

Now we discuss the
c:\Program file\
window start wit c drive \ this is called the seperation
/root/div
linux start with / - top level dir
