AWS – EC2 and its pricing plans.

INTRODUCTION

 

AWS EC2  is one of the first web services that provides re-sizeable computing capabilities within the cloud & also AWS EC2 is designed to make web-hosting cloud computing easier for developers.

Amazon EC2 instances may be charged for five ways: on demand, savings plans, reserved instances, and spot instances.

AWS Free Tier includes 750 hours of Linux and Windows, t2.micro times a month for one year. Only use EC2 micro instances to remain within the Free Tier . Furthermore information click here.

 

COMPUTE

 

Compute moreover refers to the computing power needed to meet the workload requirement. If your workload is low and you have few visitors on your website, you will need limited computing power. We need a large amount of computing power for big workload. Over time the time to calculate could change  drastically. It allows us to Acquire compute through launching virtual servers called Instances.

 

INSTANCE TYPE

 

They are defined as the virtual hardware supporting an Amazon EC2 instances.Types are mentioned below:

 

  • Instances
  • Virtual CPU’s (vCPU)
  • Memory
  • Storage
  • Network performance
  • Computer Credit

 

T2 instances are an instance of low cost, general purpose.

Prices on-demand Instance start at $0.0058 per hour. T2 instances are one of the lowest-cost instance options on Amazon EC2. These are suitable for a range of general-purpose applications such as micro-services, collaborative low-latency applications, small and medium data bases, virtual desktops, development, build and stage environments, code repositories, and software prototypes.

There are different family types . Lets try to understand it with the table given below:

 

 

Instance vCPU* CPU Credits/hour Mem (GiB) Storage Network Performance (Gbps)
t2.nano 1 3 0.5 EBS-Only low
t2.micro 1 6 1 EBS-Only low to moderate
t2.small 1 12 2 EBS-Only low to moderate
t2.medium 2 24 4 EBS-Only low to moderate
t2.large 2 36 8 EBS-Only low to moderate
t2.xlarge 4 54 16 EBS-Only Moderate
t2.2xlarge 8 81 32 EBS-Only Moderate

Sample instance type family:

Compute optimised— For workloads requiring substantial processing.

Memory optimised— For workloads which are memory intensive.

Storage optimised— For workloads which require high quantities of fast SSD storage.

GPU-based-instancesIntended for graphics and general purpose. GPU compute workloads, the Amazon web services charge you on an hourly basis.

 

The Amazon Elastic Block Store (EBS) 

 

A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerised applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS.   You can also use EBS snapshots with automated life-cycle policies to back up your volumes in Amazon S3, while ensuring your data and business continuity is protected geographically.

 

There are three different pricing types:

 

 A. ON DEMAND

 

In this the customer knows only the short-term forecasts and also in the future they will inquire for the facilities as per the demand would grow.Excellent for businessmen as they haven’t learned about the possible necessity, what level of traffic on the platform will be there, so they’ll go for On Demand.

 B. RESERVED INSTANCES 

 

In this way, the customer can predict that their workloads can reserve capacity and save  up to 75% over the hourly rateof demand. An additional advantage is that the capacity of  the AWS data centers is reserved for the customer.

 

There are different types of Reserved instance types:

 i. All Upfront: Pay for the full reservation upfront. Also there will be no monthly charges.

ii. Partial Upfront: Pay a portion of reservation upfront and after that you have pay it in monthly installments for the term.

 iii. No Upfront: Pay the full reservation upfront charges in monthly instalment for the entire term.

C. SPOT INSTANCES

 

Spot instances give’s an excellent discount.   Of spot instances, consumers decide the price they want to pay for some sort of event.   To make use of the spot instance consumer must offer above the spot price.

These will perform like all other instances of Amazon EC2 and the client will only pay the spot price for the hours the instance operates.

Instance will terminate when  :

 

  • The customer terminates them.
  • The spot price goes above the customer’s bid price.
  • There is not enough unused capacity to meet the demand for the spot instances.

SAVING PLANS

 

On the positive side a new flexible pricing mode which helps you save upto 72% on EC2 and Fargate the wages.

Important to realize customer simply commit a consistent amount of wage (Eg.$10 / hour) for one or three years & also in exchange they will receive a discount for that wage.

Furthermore Customer commits to $10 / hour of compute usages.

In addition, any usages beyond the commitment rate will be charged at the regular rates.

 

EC2 SAVING PLAN

 

  • Particularly it provides the discount up-to 72%, on the selected instance family, in specific AWS region.
  • Moreover you can change size, operating system & can modify your tenancy.

 

COMPUTE SAVING PLAN

 

  • First It gives the greatest flexibility up to 66% discount.
  • In addition You can change your instance family, change your region, change your operating system, modify your tenancy You have a compute option in which you can move from EC2 to fargate.
  • Furthermore Applied to EC2 services.

 

Getting Started with saving plan

 

  1. First Review hourly commitment.
  2. Also Select the type of saving plan.
  3. Correspondingly Select the term length.
  4. Similarly Start saving.

 

In short, AWS EC2 provides accommodations that will avail us minimize our workload and moreover they have plans for each level of business, be it astronomically immense, medium or low. In the same fashion you call it and they’ve got it. We’ll discuss EC2 instances and also EBS (Electronic Block Storage) in detail in the next blog.
