Hosting Deployment options on AWS

We have prepared few ready to use options which can later be changed as per your requirements. These requirements are based on your business scale and can be upgraded as per your choice.

Options	Description	Recommended for
Option 1 : Single Instance Deployment	All services mentioned in Commerceup architecture are installed in one single EC2 instance	This is standard and classic way of hosting any application on single EC2, Recommended for staging or mild traffic production use only.
Option 2 : Independent services instance deployment	You can use multiple instances to host your frontend, APIs layer, database, elastic search on different instances	This is used for medium to high production use by choosing different types of EC2 instances. May incur low cost but not full proof.
Option 3 : Managed services deployment	This is AWS preferred way to use AWS managed services which auto heal and auto start. This gives a great way for backup. Every service in given architecture runs on separate managed services by AWS	Recommended for high traffic and production use only. This may incur higher cost but is more reliable and secure. Gives you more flexibility over fallback, alarms, restarts and backup etc.

Merchants can choose any of the above hosting at the time of setup according to business requirement and budget. These setups can be changed or upgraded as business grows.

Estimated Usage Cost according to AWS are listed below

Below are few examples with use cases to calculate estimated pricing. These pricing are just estimate and can vary for different AWS region and services or resources used.

• API Gateway : This service is used to serve APIs and track, pricing goes as below : https://aws.amazon.com/api-gateway/pricing/

• S3 Storage : This service is used to save images, files and other assets in different buckets. https://aws.amazon.com/s3/pricing/

• Cloudfront : This service is used for distribution globally from its edge locations. https://aws.amazon.com/cloudfront/pricing/

• Data Transfer Cost : https://aws.amazon.com/blogs/architecture/overview-of-data-transfer-costs-for-common-architectures/

• EC2 : https://aws.amazon.com/ec2/pricing/on-demand/

• EKS : Managed Kubernetes is used. https://aws.amazon.com/eks/pricing/

• Elastic Load Balancing : https://aws.amazon.com/elasticloadbalancing/pricing/

• Elastic Cache : https://aws.amazon.com/elasticache/pricing

• OpenSearch Service : used for elastic search https://aws.amazon.com/opensearch-service/pricing/

• AWS Lambda Serverless pricing : https://aws.amazon.com/lambda/pricing/

You may also be entitled to get a free tier for 12 months of AWS. You can claim for 10000 USD credits if you enable the startup activation program with AWS.

Deployment Examples with estimated pricing

We have create 3 options which can be used as a reference.

Option 1

Description: Under this option, all the software components will run on a single instance. This is standard and classic way of hosting any application on single EC2, Recommended for staging and test environments

No. of Instances: 1

No. of Load Balancers: 1

No. of EKS Cluster: 1

HA: No

Backup: Manual / Can be automated using scripts

Architecture: Monolithic for DB services & Microservices for Application

Services on Instance #1

● Elastic and Kibana ● ElasticSearch (without Cluster / Replica) ● MongoDB unmanaged (without Cluster / Replica) ● Redis unmanaged (Without Cluster / Replica) ● Jenkins - Build and Deploy Pipeline

Estimated fixed cost will be for EC2 and rest will run as common pricing model as mentioned above. EC2 can be chosen as per preference but for production can be used a large machine and for staging can be a t2 medium or t3a.large.

Estimated Pricing : ~$100-200 per month excluding usage of common pricing

Option 2

Description: Under this option, all the software components will run on an individual instance.

No. of Instances: 5

No. of Load Balancers: 1

No. of EKS Cluster: 1

HA: No

Backup: Manual / Can be automated using scripts

Architecture: 3-tier for DB services & Microservices for Application

The below components will run on individual Instances:

● Elastic and Kibana ● ElasticSearch (without Cluster / Replica) ● MongoDB unmanaged (without Cluster / Replica) ● Redis unmanaged (Without Cluster / Replica) ● Jenkins - Build and Deploy Pipeline

Other cloud services will be used: ● API Gateway ● EKS ○ Ingress ○ Deployment ○ Services ● S3 and CDN ● Lambda, Cloud Function, Azure Functions ● Lets Encrypt SSL Estimated Fixed cost : $200-500 per month excluding usage of common pricing

Option 3

Description: Under this option, all the software components will be using Cloud managed services with or without HA.

No. of Instances: 5 + 8 HA Nodes

No. of Load Balancers: 1

No. of EKS Cluster: 1

HA: Yes

Backup: Automated

Architecture: 3-tier for SaaS DB services with HA & Microservices for Application

The below components will run on individual Instances using Cloud managed-services:

● Elastic and Kibana [EC2 / VM Instance / Virtual Machine] ○ HA Nodes: +2 ● ElasticSearch (with Cluster / Replica) [Opensearch]HA Nodes: +2

● MongoDB managed (without Cluster / Replica) [DocumentDB] ○ HA Nodes: +2

● Redis unmanaged (Without Cluster / Replica) [ElastiCache] ○ HA Node: +1

● Jenkins - Build and Deploy Pipeline ○ HA Node: +1

Other cloud services will be used: ● API Gateway ● EKS ○ Ingress ○ Deployment ○ Services ● S3 and CDN ● Lambda, Cloud Function, Azure Functions ● Lets Encrypt SSL Estimated Fixed Cost : $700-$900 excluding usage of common pricing as mentioned above.

Example : Estimated fixed cost for 20 million API requests traffic usage per month with Managed services deployment

Services used in middle east region	Cost	Total
