How can I design a cost-effective deployment architecture
I am a solution architect and I am tasked with designing a cost-effective deployment architecture by using the AWS elastic beanstalk for a web-based application. How can I approach this task, considering factors such as Instance types, scaling options, storage costs, and potential optimization for minimizing elastic beanstalk overall cost while ensuring optimal performance and scalability for the applications?
In the context of AWS, here are the steps and consideration given:-
Instance types
You can choose appropriate EC2 Instance types based on your resources of the application requirements. You can use the AWS cost explorer to analyze historical usage patterns and select Instances that can balance performance and cost.
Auto Scaling
You can configure auto-scaling policies based on metrics like CPU utilization, request count, or custom cloudwatch metrics. You can set scaling triggers for adding or removing Instances dynamically, optimizing resource utilization, and minimizing costs during peak and off-peak periods.
Storage costs
You can evaluate storage options such as Amazon s3 for static content, Amazon RDS for database, and Amazon EFS for shared file storage.
Optimization
You can implement performance optimization such as caching, code optimization, and resource consolidation to reduce the number of Instances required.
Here is an example given of how you can configure auto-scaling and Instance types in an elastic beanstalk environment by using AWS CLI:-
#!/bin/bash
# CloudFormation template for Elastic Beanstalk environment
Cat << EOF> elasticbeanstalk-template.yaml
Resources:
MyElasticBeanstalkEnvironment:
Type: AWS::ElasticBeanstalk::Environment
Properties:
ApplicationName: MyApplication
EnvironmentName: MyEnvironment
SolutionStackName: “64bit Amazon Linux 2 v5.4.0 running Python 3.8”
OptionSettings:

OptionName: MinSize
Value: ‘2’
