  Storages: Types: EBS - Elastic Block Storage EFS - Elastic File Storage S3 - SImple storage service Glacier - Archival storage EBS - Elastic Block Storage: - It is a type of block storage  - It can be attached only to a single instance in a single-zone   - OS volume - application critical data EFS - Elastic File storage:   -It is a type of Network shared storage  -NFS principle -common software, logs, company data -It can be accessed only in a single region. S3 - simple storage service:  -It is a type of Object storage  -It requires internet  -commercial files (photo, videos, blogs) Glacier - Archival storage:  compressed data and storing in the tape drive  company’s old data for auditing purpose – Creating extra storage: Practical Steps: lsblk (list block) mkfs.ext4 /dev/xvdf (create ext4 file system)  mkdir /java (crate a fold to attach the new disk)  mount /dev/xvdf /java (temporary mount)  vi /etc/fstab (permanent mount entry)  /dev/xvdf    /java  ext4  defaults 0 0 — Temporary m

AMI: AMI - Amazon Machine Image  AMI is a master copy of an EC2 instance with common software installed in it!  By using AMI we can save time!  – Create:           Right click instance -> images and templates -> create image – AMI Launch and Check: – Move AMI to another region:           Right-click AMI - Copy AMI - > region  

EC2: Create EC2 instance( Windows & Linux): create EC2: search ec2 service -> launch instance -> choose amazon linux (freetier) -> choose t2 micro -> leave the configure instance default -> leave the default storage option -> tags give name like (Name Linux-server) -> create new security group and add the ports (ssh/http/all-icmp) -> create a new key pair for the login password Linux Machine:  To connect the EC2 - we need either putty or MobaXterm open MobaXterm - > session -> ssh -> public ip -> username = ec2-user -> advanced settings (use private key and choose the key we downloaded)  Windows machine:  login using username = Administrator (use get password feature in instance connect to upload your .pem key and generate the password) search rdp and give public ip and user name "Administrator" and give the generated password Linux website:  – Create a website in Linux server : yum install httpd ( host a website) cd /var/ww

  What is SNMP?             SNMP is monitor protocol, Which is used do monitor 1000's Router/Switches. In case of monitoring the router status of one or two routers manually it can be easily done by human but monitoring large number of router SNMP is used.     Main Principles Of SNMP!          The SNMP uses two major principle to communicate with routers and known their status:  1) Manager SNMP                         2) Agent SNMP Manager SNMP:           The devices/Software Which used to monitor the router/ switches status is Known as Manager SNMP. Agent SNMP:           What the managers are monitoring are known as agents SNMP (eg: Routers, Switches) How it Works? First we need to create the Database which contain all the information of Router/Switches(Agents). Then by using Unique ID's we can fetch or monitor the information (eg: Hostname, Interface Status, Location, etc..,) These identifiers are refers to Objects identifiers(ODI's) This Whole  operation is refers to man

Surpassing than Raspberry pi!             The previous blog shows that the Surpassing of Embedded basic board . In this blog we are going to see surpassing of Raspberry pi. Yes As I said already they are so many boards developed for every month. In this order the most valuable board reach it way .. In this order we going to see about most popular boards in market.            They processor which are fix in surpassing boards are mini cpu . They can perform without any central processing unit. Surpassing boards!                   After their family of Raspberry pi there comes Banana pi . This is a low cost single board computers which was designed by Chinese company  Shenzhen SINOVOIP Co. Ltd. This hardware is copied of Raspberry pi .  It can work on the platform of Linux, Ubuntu, Raspbian, etc... It is works on arm processor with ram of 1gb . The banana pi alao has so many versions :) BPI - M1 , BPI - M2 , BPI - M2+ ,BPI -M3 ,Qual core etc.                          The nex

Surpassing Embedded boards🤔?             The basics board of Embedded is Arduino family . We saw in previous blog. What is surpassing ! Surpassing is nothing but more advanced. Yes there are so many advanced board in market . The next level board is to be Raspberry pi. The board is also known as mini cpu for operating . Raspberry pi!           The Raspberry pi is one of the advanced board in Embedded which is works in a platform of Python programming language . As I said already when you start your work in Arduino family you can get strong in C program and next you start your work in Raspberry pi you can get strong in Python program.              The power supply of Raspberry pi is provided by using 2.5A and 5 volts charger. The hardware devices like Keyboard and mouse can Connect to Raspberry pi . The monitor connection used to give by HDMI to VGA cable.              In Raspberry pi there is also more number of version . Each version performs specific operation . The higher v

Is any hardware for Embedded🤔?         So many have a question about any hardware tool for Embedded . Yes there is plenty of hardware performing different types of action in Various field.         Most common board used to start as new work in Embedded is Arduino Uno . This board works in programming language embedded c. It consists of both analog and digital pins for performing the duties. The power supply of 5v given to the board by cpu or any other sources such as transformer , etc... Let's join in Arduino family😉;-)           Yes there are many types of hardware boards board available in this family.Most of board are works in Embedded c platform where we can get knowledge in c program also . This is very first step to do in Embedded system . The cost of board in arduino family are less max UpTo $1000. The board in Arduino family ; . Arduino Uno . Arduino mega . Arduino nana . Arduino Due . Arduino Leonard.
