Satellite reference architecture use cases

Use cases for the Satellite reference architecture for the IBM Cloud for Financial Services typically fall into the four categories in the following table.

Table 1. Overview of use cases for the Satellite reference architecture
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.
Use Case Description
Platform modernization Innovate faster and free your team to develop applications with Red Hat OpenShift on IBM Cloud on-premises. 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.

Two uses cases from real financial institutions are presented in the following sections.

US regional bank

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.

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

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.

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
