This document mainly focuses on the hardware requirements/ AWS network architecture for installing cQube and the deployment process step-by-step.
Hardware Requirements
Create Create an AWS EC2 or AZURE VM or in LOCAL SDC or Oracle VM instance with below configurations to install all the cQube micro services.
Ubuntu 22.04 (supported)
16 GB of System RAM (minimum requirement)
4 core CPU for AWZ, AZURE, LOCAL / 2 OCPU for ORACLE (minimum requirement)
250GB HDD
...
Port 80 inbound from 0.0.0.0/0
Port 443 inbound from 0.0.0.0/0
Port 8000 inbound from nginx private ip ( to communicate with kong )
5432 inbound to the particular ip which needs access
...
Create a domain name
Configure cname of AWS ec2 or AZURE VM or LOCAL sdc or ORACLE VM instance to the domain name
Create a SSL certificate for the domain name.
IAM user and Role creation for S3 connectivity (AWS)
An AWS Identity and Access Management (IAM) user is an entity that is created in AWS to represent the person or application that uses it to interact with AWS. A user in AWS contains a name and credentials. An IAM user with administrator permissions is different from the AWS account root user. One has to create an IAM user with a supported role to provide the connectivity between EC2 and S3. The role should have list, read and write permissions
S3 Buckets:
Create following s3 buckets
Archiving
Error logging
.
IAM user and Role creation for AZURE Storage Blob Container connectivity
An AZURE Identity and Access Management (IAM) user is an entity that is created in AZURE to represent the person or application that uses it to interact with AZURE. A user in Azure contains a name and credentials. An IAM user with administrator permissions is different from the AWS account root user. One has to create an IAM user with a supported role to provide the connectivity between azure VM and blob container. The role should have list, read and write permissions.
IAM User:
Create a IAM user
Assign IAM policy to the user
Download the access key and secret keyDefault Connection String and Azure account name and account name and container name
IAM Policy:
Create a IAM policy from AWS AZURE IAM
Provide access to list, read and write the objects to s3 bucketsto azure Blob container
For Local SDC installation
If a user opting for local installation, Enter storage_type as local. Then automatically install.sh will install and configure the minio application in localhost and it will set default username and password and it will create a minio bucket as well.

...
state_name ( Enter the required state code by referring to the state list provided )
api_end_point ( Enter the url in which cqube to be configured )
Storage_type (Enter the storage_type as aws or local or azure. If User opting for aws You will be prompted with the following AWS s3 credentials to enter and it will create the s3 bucket. If s3_bucket already exists it will prompt you to enter a unique s3 bucket name. And it will be generated in the config.yml.)
s3_access_key
s3_secret_key
s3 archived bucket name
s3 error bucket name
...
...
Storage_type (Enter the storage_type as local, minio will install and configure the minio username and minio password and create the minio bucket And it will be generated in the config.yml.)
...
Storage_type (Enter the storage_type as Azure, If User opting for Azure you will be prompted with the following Azure credentials to enter and it will create an azure container , if azure container exists it will prompt to enter a unique azure container name. And it will be generated in the config.yml.)
azure_connection_string
azure_account_name
azure_account_key
...
Step - 7: Optional_variables- Database credentials contain default values. If the user wishes to enter their own credentials then the user should opt for yes to enter their credentials otherwise can opt for no when the question pops up
db_user_name ( Enter the postgres database username )
db_name ( Enter the postgres database name )
db_password ( Enter the postgres password )
...
Step - 8: Optional_variables- Read Only Database credentials contain default values. If the user wishes to enter their own credentials then the user should opt for yes to enter their credentials otherwise can opt for no when the question pops up
read_only_db_user ( Enter the read only postgres database username )
read_only_db_password ( Enter the read onlypostgres password )
Step - 9: Keycloak_variables- Keycloak credentials with Keycloak admin user name and keycloak admin password.
Keyclaok_adm_name (Enter the keycloak admin name eg: admin)
Keyclaok_adm_password (enter the keycloak admin password eg: Admin@123)
...
Step - 10: Once the config file is generated, A preview of the config file is displayed followed by a question where the user gets an option to re enter the configuration values on choosing yes. If option no is selected then the install.sh moves to the next section.
...

The cQube network setup process is described in the block diagram below:
...
Micro services Microservices Details
Following are the details of the micro-services microservices which get installed in the cqube server.
Ingestion-ms: The ingestion-ms is used to upload the data of the events, datasets, dimensions, transformers and pipeline. All these apis will be to ingesting the data into the cQube.
Spec-ms: The spec-ms is used to import schema of the events, datasets, dimensions, transformers and pipeline. All these specs will be defined by the cQube platform prior to ingesting the data into the cQube. These specifications are derived by considering the KPIs as the Indicator.
Generator-ms: The generator-ms is used to create the specs & transformers for the derived datasets. Performed aggregation logics, updating data to datasets based on transformation. Status update of file processing
Nifi-ms: Apache NiFi is used as a real-time integrated data logistics and simple event processing platform
Postgres-ms: Postgres microservice contains the schema and tables
Nginx-ms: It is commonly used as a reverse proxy and load balancer to manage incoming traffic and distribute it to slower upstream servers
Kong-ms: It is a lightweight API Gateway that secures, manages, and extends APIs and microservices.
Dashboard-ms: It consists of an angular app, it is used to visualize the datasets present in postgres-ms in the form of charts. On run time it requests spec-ms to fetch data from postgres-ms and load it into the client side(Browser)
Query_builder-ms: It consists of backend API, which consists of JWT,METRICS,QUERY apis
JWT - it will generate a jwt token to restrict the other apis.
METRICS - it consists of menus for the navigation bar and dashboard cards.
QUERY - this api used for executing the SQL queries which integrated with Dashboard-ms.
LASTMODIFIED - this api will use for the last modified data in the s3,azure and minio

Storage_type is azure enter the below variables
azure connection string
azure account name
Azure account key
azure container name
Storage_type is a local system that will automatically create the minio username and minio password and minio bucket.
minio username
minio password
minio bucket
Minino can be accessed by Dashboard with http://localhost:9001 end point, here you can see the minio bucket which is created by default and the username is minio admin and password is minio admin
