Portfolio Architecture Examples - Infrastructure Collection

Figure 1: The portfolio architecture process
For a few years now we've been working on a project we have named Portfolio Architectures. These are based on selecting a specific use case we are seeing used in the real world by customers and then finding implementations of that case using three or more products from the Red Hat portfolio.

This basic premise is used as the foundation, but many aspects of open source are included in both the process and the final product we have defined. There is a community, where we share the initial project kickoff with a group of architects and use their initial feedback from the start. We also present the architecture product we've created right at the end before we publish to ensure usability by architects in the field. The final publish product includes some internal only content around the customer projects researched, but most of the content is open and freely available through various open source channels. 

This article is sharing an overview of the product we've developed, what's available to you today in our architecture center, and concludes by sharing a collection of architectures we've published.


The basis of a portfolio architecture is a use case, two to three actual implementations that can be researched, and includes the use of a minimum of three products. This is the ideal foundation for a project to start, but we encountered a problem with use cases containing emerging technologies or emerging domains in the market. To account for these we've chosen to note the fact that these are opinionated architectures based on internal reference architectures. 

The product has been defined as complete for publishing when it contains the following content:

  • Short use case definition
  • Diagrams - logical, schematic (physical), and detail diagrams
  • Public slide deck containing the use case story and architecture diagrams
  • Internal slide deck containing both the public deck content and the confidential customer research
  • Video (short) explanation of the architecture
  • Either a technical brief document or one or more articles covering the solution architecture

Note that the items in italics are all available to anyone  in the Red Hat Portfolio Architecture Center or in the Portfolio Architecture Examples repository.

Tooling and workshops

The progress towards our products required a good idea of how we wanted to diagram our architectures. We chose to keep them very generic and simple in style to facilitate all levels of conversation around a particular use case without getting bogged down in notational discussions. 

A simple three level design for our architectures was captured by using logical, schematic, and detail diagrams. All of these have been integrated in open source tooling with pre-defined templates and icons for easily getting started. Furthermore, we've developed a tooling workshop to quickly ramp up on the design methods and tooling we've made available. It's called Designing Your Best Architectural Diagrams, has been featured in several conferences around the world.

Infrastructure collection

The collection featured today is centered around infrastructure architectures. There are currently seven architectures in this collection and we'll provide a short overview of each, leaving the in depth exploration as an exercise for the reader.

In each of these architecture overviews you'll find a table of contents outlining the technologies used, several example schematic diagrams with descriptions, and a link in the last section to open the diagrams directly into the online tooling in your browser.

Cloud to edge

This architecture covers the use case of providing a consistent infrastructure experience from cloud to edge and enabling modern containerized applications at edge.

(Note: this project is a new architecture and currently in progress, so sharing one of the schematic architecture diagrams and you can monitor this project for updates as it progresses to completion.)

cloud to edge

This use case is bringing cloud like capabilities to the edge locations.

Data center to edge

This architecture covers the use case around data center to edge where the energy (utility) infrastructure companies operate across vast geographical area that connects the upstream drilling operations with downstream fuel processing and delivery to customers. These companies need to monitor the condition of pipeline and other infrastructure for operational safety and optimization.

data center to edge

The use case is bringing computing closer to the edge by monitoring for potential issues with gas pipelines (edge).

Hybrid multicloud management with GitOps

This architecture provides a stable and simple container platform that's secure, supports a hybrid environment, and able to run on multiple cloud solution for its developers and engineers. Using an automated infrastructure as code approach that manages versioning and enabling deployments according to the supplied configurations.

hybrid multicloud management with GitOps

The use case is managing hybrid and multicloud cluster lifecycles, secure configurations and credentials. GitOps for infrastructure as code approach. Cross cluster governance and application lifecycle management.

SCADA interface modernisation

This Portfolio Architecture targets energy providers in North America that need to be compliant with NERC regulations and in order to achieve this they decide to modernise the interfaces between their business applications and their SCADA systems also for a better consumption of information that can be used in combination with AI/ML and decision management tools to better address customer needs.

SCADA interface modernisation

The use case is providing interfaces with SCADA systems that are compliant with NERC regulations, creating different layers of API gateways to protect business service depending on the network zones.

Telco 5G core: on premise

5G is the latest evolution of wireless mobile technology that aims to enable the delivery of highly immersive experiences for people and ultra reliable, low latency communication between devices. At the heart of each 5G network lies the 5G Core (5GC).

telco 5g core on premise

This portfolio architecture conceives 5G Core as a set of disaggregated, cloud native applications that communicate internally and externally over well defined standard interfaces. Each 5GC component is implemented as a container-based application and is referred to as cloud-native network function (CNF).

The use case is ultra-reliable, immersive experiences for people and objects when and where it matters most.

Telco 5G with hyperscalers

5G is the latest evolution of wireless mobile technology. In this portfolio architecture we’ll discuss an 5G solution built with open source technologies at core, that can work across any hyperscaler.

telco 5g with hyperscalers

The use case is building an adaptable, on-demand infrastructure services for 5G Core that can deliver across diverse use cases with minimal CAPEX and OPEX.

Telco radio access networks

5G is the latest evolution of wireless mobile technology. It can deliver a number of services from the network edge:

  • Enhanced mobile broadband (eMBB)

    • 5G enhances data speeds and experiences with new radio capabilities like mmWave frequency spectrum for higher bandwidth allocation and theoretical throughput up to 20Gbps.

  • Ultra-reliable, low-latency communication (uRLLC)

    • 5G supports vertical industry requirements, including sub-millisecond latency with less than 1 lost packet in 105 packets.

  • Massive machine type communications (mMTC)

    • 5G supports cost-efficient and robust connection for up to 1 million mMTC, NB-IOT, and LTE-M devices per square kilometer without network overloading.

telco radio access networks
The use case is base on the facts that digital transformation of mobile networks is accelerating and cloudification is increasing. Following the core network, radio access network (RAN) solutions are now taking advantage of the benefits of cloud computing.
