My current project is using OpenShift Container Platform (OCP), which is a container-based application run by Red Hat. We have deployed the Red Hat Fuse and 3scale applications, the API management stuff, and ESB stuff on OCP containers. In my last project, we were using on-prem enterprise systems and applications as well as the container version of Fuse. Now, it is SaaS-based.
It is deployed for our client organizations.
One of my clients is a postal and telecommunications client. We do some internal systems integrating with them, some scheduled jobs from one system to another system, and data transfers. There are some of the data integrations, postal integrations, and their integrations with different banks on payments. Therefore, we are using Fuse ESB for this. On top of that, we use the 3scale API Management platform, which is also an acquired Red Hat, open-source, SaaS platform for the API management layer. This is basically the use case for data transfers and data transformations from one system to another. In every other project, the use cases are similar in nature.
For some security layers on systems, we use OpenID. For integrations with banks, we always use SSO-based integrations.
Our client is using the private cloud with its own data center, but interim projects are managed by the client. The services run on 3scale, so the ESB is managed and supported by Red Hat.
Red Hat Fuse offers hybrid, on-prem, and cloud versions. The cloud version is managed by IBM Cloud, which is well-supported, but you can set your infrastructure in any cloud version, such as GCP or AWS. Basically, Red Hat-managed infrastructure is on IBM Cloud.
