What is AMI in AWS?

AMI stands for Amazon Machine Image

We can take the complete image/backup of any EC2 Instance easily.
How do we create AMI?
This is very simple
Select the Instance - Go to Actions - Choose Image & Templates - Create Image
We need to specify the Image name, Description while creating an image.

Once the AMI has been successfully created, please keep an eye on the status to confirm the AMI is ready or not.


We can use AMI in the same region & also between multiple regions.

Same Region:
If we have AMI in one region, and if we need to replicate the same, then we can easily do this by launching a new EC2 Instance with the help of My AMI.


Multiple Regions:
If we have AMI in one region, and if we need to replicate the same in another region,
then we can easily do this by copying AMI from one region to another region
Once the copying of AMI is done from one region to another region
We can launch a new EC2 Instance in the 2nd region with the help of copied AMI

Let's understand more about the EC2 dashboard.

EC2 Dashboard is Region specific
If we create EC2 machines in one region, then they won't be visible in another region.
AWS Management Console is Region specific dashboard
Every region is independent.
The experience of creating the EC2 instance is always the same in any region.

What is Scale-up in AWS?
What is Scale down in AWS?
Scale-up and Scale down also known as Vertical scaling in AWS
What is Scale in AWS?
What is Scale-out in AWS?
Scale in and Scale-out also known as Horizontal scaling in AWS


Scale-up in AWS is increasing the hardware configuration of the specific instance
-----------------------------------------------------------------------------------------------------------

Let's take a look at Scale-up in AWS.
How do we increase the hardware configuration such as Harddrive/RAM/CPU?

Harddrive - We can increase from the Volumes - Actions - Modify volume - Specify new size - Confirmation to modify.
For this, we don't have to stop the instance.

RAM&CPU - We must stop the instance from making any changes as this is changing the instance type from one instance to another instance
Please note that the changes to RAM&CPU go together as we need to use the existing instances given by AWS.
Select the instance - Actions - Instance settings - Change instance type - Select the new instance correctly - Apply.




Scale down in AWS is decreasing the hardware configuration of the specific instance
----------------------------------------------------------------------------------------------------------------

Let's take a look at Scale down in AWS.
How do we decrease the hardware configuration such as Harddrive/RAM/CPU?

Harddrive - We can decrease from the Volumes - Actions - Modify volume - Specify new size - Confirmation to modify
For this, we don't have to stop the instance.

RAM&CPU - We must stop the instance from making any changes as this is changing the instance type from one instance to another instance
Please note that the changes to RAM&CPU go together as we need to use the existing instances given by AWS.
Select the instance - Actions - Instance settings - Change instance type - Select the new instance correctly - Apply.




Scale-out - Without making any changes to existing EC2, and launching a new instance is nothing but Scale-out.

Scale in - Without making any changes to existing EC2, and removing an instance is nothing but Scale in

Example of Horizontal scaling: Autoscaling

How do we protect critical EC2 Instances without any accidental termination?

To overcome the accidental termination, we have a termination protection feature in AWS.

Where can we see this option?

Select the EC2 Instance - Go to Actions - Instance settings - Change termination protection - Enable - SAVE
Once this is enabled, we can avoid accidental termination.


Removing the termination protection is also the same
Select the EC2 Instance - Go to Actions - Instance settings - Change termination protection - Remove Enable option - SAVE

What is status checks in AWS?

We need to understand the EC2 Instance status check when the instance is terminated.
We also have to understand the EC2 Instance status check when the instance is created/started - Initializing, 2/2 checks passed.

Any EC2 Instance should pass the below status checks
Instance status check(1/2 passed)
System status check (2/2 passed)

Instance status check usually refers to OS(Operating System)
System status check usually refers to Hardware

When the Instance status check fails, we need to reboot the Instance as this is OS related.

When the System status check fails - automatically, the Instance status check would also get failed - We need to Stop & Start the EC2 Instance.

What is Autoscaling in AWS?

Autoscaling is nothing but an extension to load balancing in AWS.

We use load balancing along with the Autoscaling feature.

To recap,
The load balancer receives incoming requests/traffic and distributes the requests/traffic to registered target instances.


What is the Advantage of a Load balancer?
If one target instance is down/unhealthy, we can still get the application from other target instances.
Also, there is no limit of instances while attaching to the load balancer.


Companies use Load balancers & Autoscaling as a part of their business.

Example:
Let's consider that CompanyA is using a Load balancer
How many instances can CompanyA use as a part of the load balancer?
When there is an increase/decrease in traffic, how the company can handle this scenario?
No of the instances we attach shouldn't be static, considering the business as a priority.
No of the instances we attach should be purely based on the traffic
When traffic increase-we, need more no of EC2 Instances
When traffic decrease-we, need less no of EC2 Instances
No of the instances we attach should be dynamic.
Based on the traffic, the scaling should happen dynamically.

The auto-scaling feature helps us automatically scale up the infrastructure and scale down the infrastructure based on the traffic.


The following are the sequence of steps we need to perform while working with Autoscaling.
Step1 - Create a load balancer
Step2 - Create Launch configuration
Step3 - Create Topic in SNS(Simple Notification Service)
Step4 - Create Autoscaling group(min/max)
Step5 - Create Alarm in CloudWatch (This is condition)
Step6 - Add policy in Auto Scaling (This is an action for the condition)




Step1 - Create load balancer(For WebServers, we use Classic Load Balancer)
Specify Load balancer name
Create security group
Specify the security group name
Open SSH(22) and HTTP(80) ports for communication
Configure Health Check
Create



What is Launch configuration & Why do we need Launch configuration?
When traffic increases, Autoscaling should add the new EC2 instances automatically.
What happens when there is unexpected traffic on any special day/occasion? For this, we have business analysts who give instructions to the infrastructure team.
Based on the previous statistics, business analysts develop some plans and give their inputs to the internal teams accordingly to be prepared for any unexpected traffic.
When traffic decreases, Autoscaling should remove the EC2 instances automatically.
There is no manual process here, especially while adding or removing EC2 instances.
The most important questions as a part of Autoscaling are
What would be the RAM for the new EC2 instances?
What would be the HDD for the new EC2 instances?
What would be the Processor for the new EC2 instances?
What would be the OS for the new EC2 instances?
What are the ports we need to open for new EC2 instances?
Should we install any software while the EC2 instance gets created?
We need to pre-define all the above as part of the Launch configuration so that auto-scaling helps us automatically scale up the infrastructure and scale down the infrastructure based on the traffic.




Step2 - Create Launch configuration (This is a part of Autoscaling where we can see this from the Autoscaling Menu)
Specify the launch configuration name
Choose the AMI Image/ID correctly(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
Choose the instance type correctly(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
Since this web server in our example, go to advanced details - user data - use the bootstrap script here(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
Storage - EBS volumes - Select the Size correctly(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
Security groups - We need to assign a security group correctly(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
Key pair - We need to choose the key pair correctly(Autoscaling is going to use while launching new EC2 instances as a part of scaling up the infrastructure)
The purpose of the key pair is to get connected to EC2 Machine.




Step3 - Create Topic in SNS(Simple Notification Service)
What is Topic & Why do we need SNS?
The topic is nothing but a group where the entire group can receive email notifications.
SNS stands for Simple Notification Service
When the traffic increases, auto-scaling happens as per the configuration. We need to receive email notifications to scale up the infrastructure and scale down the infrastructure in this scenario.
Go to Application Integration - Simple Notification Service
Click on Topics - Create Topic - Choose standard
Specify Topic Name -
Specify Topic Display name -
Create
Now we need to add emails id's to the Topic.
Go to the Topic - Look for the subscription option
Click on create subscription
Protocol - Email
Endpoint - Specify email id OR group of email ids to receive notifications
Create subscription
We need to confirm email as a part of validation to receive notifications as this is mandatory.





Step4 - Create Autoscaling group(min/max)
We need to create an Autoscaling group based on the Launch configuration that we have created.
Select Launch configuration - Go to Actions - Create Autoscaling group
Specify Autoscaling group name
Choose VPC correctly(This is where Auto scaling happens)
Subnet - Choose this correctly(Subnet is nothing but a partition in your AWS Region. You may have more than one subnet, hence choose the subnet correctly so that the Autoscaling happens in the given subnet partition)
Load balancing - Attach to an existing load balancer - Choose from Classic Load balancers - Select your Load balancer correctly so that whenever Auto scaling happens, automatically EC2 Instances would be a part of Load balancer by default.
Group size - (Desired-1 ) (Min -1) (Max -1) We can also use any capacity, but as a part of learning/training, a minimum is recommended. At the company's we follow the size based on the statistics of the previous sales/business.
(Desired is nothing but to start with) (Minimum is minimum instances) (Maximum is maximum instances)
Create Autoscaling group
Check the status of the Autoscaling group
Add notifications - Select topic where we need to receive notifications
Add tags appropriately
Review
Create
Creation may take some time, depending on the configuration we have specified. Keep checking the status, and we can proceed with the next step when the status is





Step5 - Create Alarm in CloudWatch (This is condition)
How do we measure the traffic for the auto-scaling?
When Traffic increases/Traffic decreases, what is the condition?
Creating an alarm is nothing defining a condition when there is traffic increase/decrease.
We have a metric known as CPUUtilization provided by AWS
If CPUUtilization>70%, then create new EC2 or create more EC2 based on the business requirement
If CPUUtilization<30%, then remove EC2 or remove more EC2
In this scenario, we have to create 2 Alarms in CloudWatch
Alarm1-CPUUtilization-GTE70
Alarm2-CPUUtilization-LTE30



In the above step, we have created 2 conditions.
Now, what is the action to take for every condition is nothing but adding policy in Autoscaling.




Step6 - Add policy in Auto Scaling (This is an action for the condition)
In this scenario, we have to create 2 policies from the Dynamic scaling policy
Policy1 is for Alarm1-CPUUtilization-GTE70 (Adding EC2 Instances)
Policy2 is for Alarm2-CPUUtilization-LTE30 (Removing EC2 Instances)
Once the policies are created, we can take appropriate action accordingly


The Application should not go down no matter what happens.



Deleting process:
============
1)Delete AutoScaling
2)Delete launch configuration (Instances will be terminated automatically)
3)Delete Load balancer
4)Delete Topic
5)Delete Alarm

What is a Load balancer & Why do we need a Load balancer?

A load balancer accepts incoming traffic from users/clients and routes requests to EC2 Instances or targets.

The load balancer also monitors the health of its registered targets and ensures that it routes traffic only to healthy targets.

When the load balancer detects an unhealthy target, it stops routing traffic to that target.

It then resumes routing traffic to that target when it detects that the target is healthy again.


The load balancer is region-specific.

1:Define Load Balancer
2.Assign Security Groups
3.Configure Security Settings
4.Configure Health Check
5.Add EC2 Instances
6.Add Tags
7.Review

Once the Load Balancer is successfully created, we can see the DNS Name of the load balancer on the dashboard.

How to test the Load Balancer?
Go to browser - Type DNS Name and see what the response we're getting is
We should get a response from all the machines that are associated with Load Balancer
This confirms that the load balancer is working as expected.

How to launch AWS Linux Instance?

EC2 stands for Elastic Compute Cloud

In this, let's discuss how to create Linux EC2 Instance from AWS Management Console
1.Choose AMI correctly
2.Choose Instance type appropriately
3.Configure Instance
4.Add storage
5.Add tags
6.Configure security group(SSH Port 22 should be opened)
7.Review

AWS provides a .pem file while launching any Instance.

Using PuTTYgen tool - We can convert (.pem) to (.ppk)

Now we can get connected to Linux Machine using Putty.

In order to use Putty, we need Hostname or IP Address & (.ppk file)

PPK is nothing but (Putty Private Key)



Each Linux instance launches with a default Linux system user account.
The default user name is determined by the AMI that was specified when you launched the instance.

For Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user.

For a CentOS AMI, the user name is centos.

For a Debian AMI, the user name is admin.

For a Fedora AMI, the user name is ec2-user or fedora.

For a RHEL AMI, the user name is ec2-user or root.

For a SUSE AMI, the user name is ec2-user or root.

For an Ubuntu AMI, the user name is ubuntu.

Otherwise, if ec2-user and root don't work, check with the AMI provider.

1.Choose AMI correctly
2.Choose Instance type appropriately
3.Configure Instance
4.Add storage
5.Add tags
6.Configure security group(RDP Port 3389 should be opened)
7.Review

AWS provides a .pem file while launching any Instance.

We need RDP(Remote Desktop Protocol) to get connected to Windows Machine.

We need to make sure that we have DNS Name, Username & Password.

To get the password, we need to upload the downloaded .pem file and then decrypt the password to get the real password to log in to the Windows Instance.

Have you accidentally deleted Default VPC from your AWS Account?

Do you want to recreate your Default VPC using AWS Management Console?

It's straightforward.

Go to AWS Console

Click on Your VPC from VPC Dashboard

Go to Actions - Select Create Default VPC

Create


Please note that a default VPC enables you to launch Amazon EC2 resources without having t create and configure your own VPC and subnets. AWS creates a default VPC with a default subnet in each Availability Zone, an Internet gateway and a route table with a route to the Internet gateway.

DevOps is an innovative method for building and delivering quality software.

DevOps is a combination of Dev+Ops where Dev stands for Development & Ops stands for Operations.

DevOps is all about bringing development and operations activities together.

Implementing DevOps is not just about tools; it is also about how people work and the processes they use.
