Establish container portability and PaaS foundation for developer services and digital supply chain operations. Achieve improved cybersecurity with industry-leading Keep Your Own Key encryption. | | Concentration risk | Mitigate regulatory concerns about concentration risk by using a hybrid cloud deployment model that uses Satellite to extend secure Financial Services Validated offerings from IBM Cloud to your data center. | | Data residency| Manage local data requirements — storage (residency) and legal protections (sovereignty) — by keeping data in-country and accessing public cloud services. Improve data privacy (cybersecurity) for regulated data with industry-leading Keep Your Own Key encryption. | | AI and automation | Gain new insights and process automation by enhancing databases on-premises with IBM Cloud Pak AI and automation services that are deployed with Red Hat OpenShift on IBM Cloud. Maintain control of data on-premises for performance, sovereignty, and regulatory requirements. | {: summary="The rows are read from left to right. The use case title is in the first column. The second columns describes the use case referenced in the first column."} {: caption="Overview of use cases for the Satellite reference architecture" caption-side="top"} Two uses cases from real financial institutions are presented in the following sections. ## US regional bank {: #satellite-architecture-use-cases-1} During a time-sensitive merger, a US regional bank needed to integrate two entities’ IT operations securely and bring consistency across container platforms in on-premises branch locations without adding overhead. Satellite enabled the customer to establish a location that used its existing data center infrastructure and create multiple Red Hat OpenShift on IBM Cloud clusters so that teams could build and host containerized workloads in a consistent way and pay only for what they consumed. This scenario is an example of using Satellite for platform modernization. The following diagram shows a high-level overview of the architecture that is used by this financial institution. ![High-level modification of Satellite reference architecture for the first institution](../images/satellite-use-cases/satellite_use_case_1_beta2_04_06.svg){: caption="High-level modification of Satellite reference architecture for the first institution" caption-side="bottom"} Key features of their approach include: - Using VMWare or other virtualization infrastructure to provide the hosts in the Satellite location. - Leveraging a proxy that they manage for traffic to and from the Satellite location. - Running Satellite-enabled Red Hat OpenShift on IBM Cloud for their workloads and exploring other Satellite-enabled services in later phases when they become Financial Services Validated. - Hosting on-premises databases on virtual machines outside the Satellite location within the enterprise. - Placing management tools in virtual servers within their IBM Cloud account. - Using the following services on IBM Cloud: - IAM for identity and access management - Activity Tracker Event Routing to collect IBM Cloud audit events - Object Storage for backup and archiving data ## Multinational bank {: #satellite-architecture-use-cases-2} A multinational bank wanted to ensure they were following local requirements for data residency by keeping data in country when they were accessing public cloud services. The Satellite reference architecture was a perfect fit for them. The following diagram shows a high-level overview of the architecture that is used by this second institution. ![High-level modification of Satellite reference architecture for the second institution](../images/satellite-use-cases/satellite_use_case_2_beta2_04_06.svg){: caption="High-level modification of Satellite reference architecture for the second institution" caption-side="bottom"} Highlights of their architecture include the following: - Using on-premises virtual infrastructure for the Satellite location - Using a proxy that they manage for traffic to and from the Satellite location - Running Satellite-enabled Red Hat OpenShift on IBM Cloud for their workloads - Integrating with various on-premises solutions (outside of the Satellite location) for logging, monitoring, image registry, and DevOps - Using the following services on IBM Cloud: - IAM for identity and access management, federated with an external identity provider (Active Directory Federation Services) - Object Storage for Red Hat OpenShift on IBM Cloud control plane backups - Red Hat NTP to sync the time on all nodes ## Next steps {: #next-steps} - [Satellite shared responsibility model](https://cloud.ibm.com/docs/framework-financial-services?topic=framework-financial-services-satellite-architecture-shared-responsibilities&format=markdown) - [Satellite architecture best practices](https://cloud.ibm.com/docs/framework-financial-services?topic=framework-financial-services-satellite-architecture-best-practices&format=markdown)
