4-AWS Ec2 Components

4-AWS Ec2 Components

by | Nov 28, 2022 | Linux

 

EC2 Access:-

EC2 Access → To access instances, you need a key I and Key pair Name.
→ You Can download the Private key Only Once.
→ The Public Key is Saved by AWS to match it to the Key pair name, and the Private key is when you try to login to the EC2 instances.
→ Without Key pair you Cannot access instances via RDP or SSH.
→ There are 20 EC2 instances Soft Limit per region, you Can Submit a Request to AWS to increase it.

Ec2 Status Check:-

Ec2 Status Check

 

 → By default AWS EC2 Service performs automated Status checks every minute.
→ This is done on every running EC2 instance to identify any Hw or software issue.
→ Status check is built into the AWS EC2 instance.
→ They Cannot be Configured, deleted, or disabled.
→ EC2 Services Can Send its metric Data to AWS Cloudwatch every 5 minutes (enabled by default).
→ Enabled detailed monitoring is Chargeable and Sends matric every 1 minute.
→ You are not charged for EC2 instances, if they are stopped, however, attached EBS Volumes incur charges.

 

When you stop an EBS Backed EC2 Instance → Instances perform a Shutdown.
→ state changes from Running Stopping.
→ EBS Volumes remain attached to the instance.
→ Any data cached in RAM or instances store volume is gone.
→ Instances retain its private IPv4 or any IPv6 address.
→ Instances releases its public LPv4 address back to Aws Pool.
→ Instances Retain their Elastic IP address.

 

 

EC2 Termination → when you terminate a Running instance the instance stakes change as follows.
Running → shutting down → Terminated.
→ During the shutting down and Terminated states, you do not incur Charges.
→ By default EBS Root Devices Volumes have been deleted Automatically when the EC2 instances are terminated.
→ Any additional (non-boot/boot) Vokimes attached to the instances by default, persist after the instance is terminated.
→ You Can Modify both behaviors by Modifying the ‘Delete on Termination’ attribute of any EBS Volumes during instances launch or while Running.
→ Enable EC2 Termination Protection against accidental Termination.

 

EC2 Metadeta:-

EC2 Metadeta

 

 This is instance data that you can use to configure or manage the instance.
eg:- IPv4 addresses, [Pu6 addresses, DNS hostname, AMI-id, Instance ID, Instance Type, local hostname, public keys, Security groups.→ Metadata Can be Only viewed from within the instance itself ie you have to log in to the instance.
→ Metadata is not protected by encryption, anyone that has access to the instance.→ Can view this data To View instance Metadata, GET http://169254169254/latest/Metadata

 

Instances User data:-

Instances User data → data Supplied by the User at instance launch in the form of a Script to be executed during the instance boot.
→ User data is limited to 16 KB.
→ You Can Change User data, by Stopping EC2 first.
→ User data is not encrypted.

 

Elastic Block Storage (NAS)

Elastic Block Storage (NAS) → The storage is called (EBS block volume) and the instance is called EBS Backed Instance.
→ Most Common Replicate with A-Z.
→ EBS Volumes attached at launch are deleted when the instance terminates.→ EBS Volumes attached to a running instance are not deleted when the instance is terminated but are detached with data interact.

 

Instance Storage  (CDAS)

Instance Storage (CDAS) → Physically attach to the host Server.
→ Data not lost when os is Rebooted.Data lost when:
→ Underlying drive fails.
→ Instance is stopped or terminated.
→ You Can’t detach or attach to another.
Do not Rely on for Valuable long-term data.
3-AWS Ec2 Purchasing Options

3-AWS Ec2 Purchasing Options

by | Nov 28, 2022 | Linux

Ec2 Instance Purchasing Options

There are four ways to pay for amazon EC2 Instances ie:- On-Demand, Reserved Instance, and Spot Instance.

You can also Ply for Dedicated Host which provides you with EC2 Instance Capacity on Physical servers dedicated for your Use.

 

1 On-demand → AWS on-demand Instances are Virtual servers that run in AWS or AWS Relational Database Service (RDS) and are purchased on a fixed Rode per Hour.

→ AWS Recommends using On-demand Instances for applications with Short term irregular workloads that Cannot be interrupted.

→ They are also Suitable for use during the testing and development of applications on EC2.

→ With On-demand instances, you only pay for the EC2 instances you use.

→ The Use of on-demand instances frees you from the Cost and Complexities of planning, purchasing, and maintaining hardware and transforms what are commonly Large Fixed Costs into much Smaller Variable Costs.

→ Pricing is per instance-hour Consumed for each instance from the time an instance is launched until it is terminated or stopped.

→ Each partial instance hour consumed will be billed per second for Linux Instances and as a full Hour for all Other Instance types.
2 Dedicated Instance → Dedicated instances are run in a VPC on Hardware that is dedicated to a Single Customer.

→ Your dedicated instances are physically isolated at the host hardware level from instances that belong to other AWS Accounts.

→ Dedicated instances may share Hardware with other instances from the Same AWS Account that is not a dedicated instance.

→ Pay for dedicated Instances On-demand Save up to 70% by purchasing Reserved instances or save up to 90% by purchasing Spot Instances.
3 Dedicated Host → An Amazon EC2 Dedicated Host is a

physical server with EC2 Instance Capacity fully Dedicated to your Use.

→ Dedicated Host can help you address Compliance requirements and Reduce costs by allowing you to use your existing Server Bound Software licenses.

→ Pay for a Physical Host that is fully dedicated to Running Your Instances, and bring your existing per-Socket, per-Core per-VM Software license to Reduce Cost.
4 Schedule Instance → Schedule Reserve Instances enable you to purchase Capacity Reservations that recur on a daily, weekly, or monthly basis, with a specified Start time and Duration, for a One-Year term.

→ You Reserve the capacity in advance So that you know it is available When you need it. You pay for the time that the instances are Scheduled, even if You do not use them.

→ Schedule instances are a good choice for Workloads that do not run Continuously, but do run on a regular Schedule.

→ Purchase instances that are always available on the Specified Recurring  Schedule, for a one-year term.

for eg:- You Can use Schedule instances for an application that runs during business hours or for Batch Processing that Runs at the end of the Week.
5 Reserved Instance → Amazon EC2 RI provides a significant discount (up to 75%) Compared to On-demand pricing and provides a Capacity Reservation when Used in a Specific Availability Zone.

→ Reserved instances give you the option to Reserve a DB instance for a one or three-year term and in turn receive a significant discount Compared to the On-demand Instance pricing for the DB instances.

→ Standard RI:- These provide the most significant discount (up to 75% of on-demand) and are Best Suited for steady-state – State Usage.

→ Convertible RI:- These provide a discount up to 54%) and the Capability to change the attributes of the RI as long as the Exchange Results in the Creation of Reserved instances of greater or equal value.

Schedule RI:- These are available to launch within the time window you Reserve.
6 Sot Instance → Amazon EC2 Spot Instances let you take advantage of unused Ec2 Capacity in the AWS Cloud Spot Instances are available at up to 90% discount Compared to On-demand prices

→ You Can use Spot – Instances for various test & Development Workloads.

→ You also have the Options to hibernate, Stop or terminate your Spot instances when EC2 Reclaims the Capacity Back with two minutes of notice.

→ When Would my Spot Instance get interrupted?

The primary reason would be Amazon EC2 Capacity Requirement (eg-On-demand or Reserved instances) Secondarily if you have chosen to set a ‘max. spot price and the spot price rises above this

2-AWS Types of EC2 Instances
