Hybrid cloud is a modern IT architecture that allows organizations to run applications and store data across both on-premise and cloud environments. By leveraging the best of both worlds, organizations can optimize their IT infrastructure, reduce costs, and improve efficiency. Building a hybrid infrastructure between an on-premise system and AWS cloud can be a complex process, but the benefits are worth the effort. In this article, we will dive into the key steps involved in creating a successful hybrid infrastructure, including network connectivity, data integration, application deployment, monitoring and management, and security. By following these steps, organizations can ensure a seamless and secure integration of their on-premise and AWS cloud environments.
1. Connectivity: To establish a secure and reliable connection between your on-premise environment and AWS cloud, you can use either AWS Direct Connect or a VPN.
AWS Direct Connect provides dedicated, high-bandwidth network connections between your data center and AWS. It helps to reduce network costs, increase bandwidth, and improve network reliability compared to a public internet connection.
A VPN (Virtual Private Network) allows you to securely extend your on-premise network to the AWS cloud over the internet. It uses encryption to protect the data in transit and helps you to securely access AWS resources from your on-premise environment.
Example: A financial services company has sensitive customer data stored on-premise and wants to move some of its applications to the cloud. The company uses AWS Direct Connect to create a dedicated, high-speed connection between its data center and the AWS cloud. This helps the company to securely and reliably transfer customer data to the cloud and access it from the on-premise environment.

2. Data Transfer: To transfer your data from on-premise to AWS cloud, you can use AWS Data Migration Services such as AWS Database Migration Service (DMS) or AWS Storage Gateway.
AWS Database Migration Service helps you to migrate your databases to the cloud with minimal downtime. You can choose to replicate your database to an Amazon Relational Database Service (RDS) instance, Amazon Aurora, or an EC2 instance running SQL Server.
AWS Storage Gateway is a hybrid storage service that allows you to transfer data between your on-premise environment and the AWS cloud. You can use it to store your data in the AWS cloud and access it from your on-premise environment using standard file protocols like NFS and SMB.
Example: A retail company wants to move its sales data to the cloud to improve its reporting and analytics capabilities. The company uses AWS Database Migration Service to migrate its sales database to an Amazon RDS instance. This helps the company to access its sales data in real-time and use AWS analytics services to gain insights into customer behavior.

3. Identity and Access Management: AWS Identity and Access Management (IAM) allows you to manage and secure access to AWS resources from your on-premise environment. You can use IAM to create and manage users, groups, and permissions for your AWS resources.
Example: A healthcare company has multiple employees accessing its AWS resources from the on-premise environment. The company uses IAM to create a set of permissions for each employee, ensuring that each employee has only the necessary access to AWS resources. This helps the company to maintain the security and compliance of its AWS resources.

- AWS Single Sign-On (SSO)
4. Network Integration: To integrate your on-premise network with the AWS network, you can use AWS Transit Gateway. It allows you to connect multiple Amazon Virtual Private Clouds (VPCs) and on-premise networks using a single entry point. This helps you to simplify network management and provide centralized security.
Example: An enterprise company has multiple business units, each with its own network. The company uses AWS Transit Gateway to connect all its business units to the AWS cloud, enabling it to share resources and data between units and simplify network management.

5. Application Deployment: When deploying applications in a hybrid infrastructure, you have the flexibility to choose the appropriate AWS services based on your specific requirements. Some applications can be deployed entirely in the cloud, while others may need to remain on-premise for compliance or performance reasons.
AWS provides a range of services for deploying and running applications in the cloud, including Amazon Elastic Compute Cloud (EC2), Amazon Elastic Container Service (ECS), and AWS Elastic Beanstalk.
Example: A media company has a video editing application that needs high-performance computing capabilities. The company deploys the application on an EC2 instance with GPU support, while storing the video files in Amazon S3. This helps the company to take advantage of the scalability and performance of the AWS cloud while keeping its video files secure and accessible from the on-premise environment.

6. Monitoring and Management: AWS provides a range of management tools to help you monitor and manage the performance of your hybrid infrastructure. Amazon CloudWatch and AWS Systems Manager are two popular tools that you can use to monitor the health and performance of your infrastructure and manage your AWS resources.
Example: An e-commerce company uses AWS Systems Manager to automate routine tasks, such as patch management and software deployment. The company also uses Amazon CloudWatch to monitor the performance of its EC2 instances and RDS databases in real-time, ensuring that its customers have a seamless experience.

- AWS Systems Manager
7. Security: Ensuring the security of your hybrid infrastructure is critical to the success of your cloud adoption. AWS provides a range of security services, such as AWS Security Hub and Amazon GuardDuty, to help you maintain the security and compliance of your infrastructure.
Example: A government agency has sensitive data stored in the AWS cloud and on-premise. The agency uses AWS Security Hub to centralize security findings from multiple AWS services, such as Amazon GuardDuty, Amazon Inspector, and Amazon Macie. This helps the agency to quickly detect and respond to security threats, maintain the security of its data, and comply with regulations.

In conclusion, building a hybrid infrastructure between an on-premise system and AWS cloud can provide organizations with greater flexibility, scalability, and cost-effectiveness. By carefully planning and implementing the key steps involved, such as network connectivity, data integration, application deployment, monitoring and management, and security, organizations can ensure a smooth and secure integration of their on-premise and AWS cloud environments. The benefits of a hybrid infrastructure include reduced costs, improved performance, increased agility, and better security. By embracing the hybrid cloud model, organizations can stay ahead of the curve and achieve their IT goals in a rapidly changing landscape. With the right approach, a hybrid infrastructure can be a powerful tool for organizations of all sizes to unlock the full potential of their IT infrastructure and achieve their business objectives.
