Designing the architecture for deploying a hybrid cloud model on AWS requires careful planning and consideration of the organization’s needs and objectives. Note that this is beyond the scope of what you are expected to put into practice, but this will be useful when you look at how it is done in industrial contexts. Let’s walk through the steps:
Determine your hybrid cloud strategy: Before you begin designing your hybrid cloud architecture on AWS, you must define your hybrid cloud strategy. This involves identifying which workloads will be deployed in the public cloud and which will remain on-premises, as well as the data and application integration requirements.
Choose the right AWS services: AWS offers a wide range of services that can be used in hybrid cloud environments. It’s important to choose the right services that fit your specific use case and can seamlessly integrate with your on-premises infrastructure.
Build a secure network architecture: A secure network architecture is critical to ensuring the protection of your data and applications in a hybrid cloud environment. This involves configuring your virtual private cloud (VPC) and subnets, establishing secure connectivity between your on-premises environment and AWS, and implementing appropriate security controls.
Define your data storage strategy: Data storage is a key component of any hybrid cloud architecture. You need to decide how your data will be stored, where it will be stored, and how it will be accessed. This may involve leveraging AWS storage services such as Amazon S3, Glacier, or EBS, as well as on-premises storage solutions.
Ensure high availability and disaster recovery: Hybrid cloud architectures must be designed to ensure high availability and disaster recovery. This involves leveraging AWS services such as Elastic Load Balancing, Auto Scaling, and Route 53 to distribute traffic across multiple instances and regions, as well as implementing backup and recovery solutions.
Implement monitoring and management tools: To effectively manage your hybrid cloud environment, you need to implement monitoring and management tools that can provide visibility into your on-premises and AWS resources. This may involve using AWS CloudTrail, CloudWatch, and other third-party tools.
By following these steps, organizations can design a hybrid cloud architecture on AWS that meets their specific needs and provides the flexibility, scalability, and cost-efficiency of cloud computing, while also maintaining control over their sensitive data and applications.
The following figure shows an AWS architecture for a hybrid deployment:

The environment is well-integrated and is where AWS services are leveraged alongside an on-premises data center. The infrastructure is designed for resilience and is spread across multiple Availability Zones, with a clear distinction between handling regulated and unregulated workloads, suggesting a setup that is both compliant and performance-optimized.
Secure connectivity between the cloud and on-premises components is established via a site-to-site VPN, with the API gateway serving as a critical point of management and access control for APIs. This enables a seamless and secure interaction between cloud-hosted services and on-premises resources, allowing for a centralized approach to managing application interfaces.
Finally, the use of ECS in both the cloud and on-premises indicates a containerized approach to application deployment, providing the flexibility to run workloads where they are most appropriate, whether it’s for compliance, performance, or other operational efficiencies. This duality in container services underscores the architecture’s readiness for a dynamic and scalable application landscape that’s well-suited for modern enterprise needs.
