Editor's Notes
- Learn, Volvo Peter Miklosik, Purushotham Muktha Arne Hjelmqvist Microsoft Ed Burns Caroline Atelius Forms and reports with WLS, running this on Premise Legacy application Oracle Linux 7.4 WLS 1212.2.1.0 FMW 12c Oracle DB They do have 10g, but they are moving that to 12c before moving to the cloud Oracle Restful Datasource (ORDS), integrates via JDBC. If you are using JPA, it just works Forms and reports, report builder. Long term goal is to allow this full system to support dynamic scale up/scale down, with quick responsiveness. The existing WLS Kubernetes Operator does not support the full FMW. JDK 1.8u72. This needs to be upgraded because it is not docker friendly. 1. They do have 10g, but they are moving that to 12c before moving to the cloud 2. Oracle BI Publisher 3. Shut down the datacenter and move it to the cloud. Peter suggest do the office stuff local to Gothenburg first, then do the factories.
- They are starting to talk about serverless. But not in this area. We can follow up with them about Azure Functions. This would be a complete rewrite.

- Would note here that at the time of writing, Functions 2.0 supports Java SE 8 LTS. Java SE 11 support should be coming soon.
- Would provide a development example or two in order to crystallize implications. For example, if you bundle Zulu in a Docker image and run it on AKS, you are fully supported via Azul for any version.
- Would discuss a bit here how Jenkins works on Azure even though it isn’t managed. Setup on IaaS using an available template (or do it yourself starting from OS). Use available Azure Jenkins plugins/Azure Pipelines to deploy artifacts to Azure and integrate with GitHub, etc.
- Their existing IDE is basically forms and reports. They have .NET, so they use Visual Studio.
- Mention that we as an industry have finally achieved the dream of software re-use.
- This one shows a very simple, but also very commonplace solution with three JBoss EAP inscances running in VMs, fronted by an Azure load balancer, connecting with App Server JDBC connection to an Oracle database, and using the elastic stack for logs. Infinispan is a distributed in-memory key/value data store with optional schema, available under the Apache License 2.0.
- This is a more involved solution
- It is a good idea to close this section with a demo. The demo setup instructions are on GitHub. Please review it. Reach out for help if needed. Feel free to highlight the parts most important to the customer.

- JOEY In a traditional Red Hat OpenShift Container Platform deployment, you need to deploy and manage a lot of supporting infrastructure. You end up managing a lot of things yourself, from cluster creation, network configuration, monitoring and logging, to securing, patching and updating the cluster. This takes time and effort. Cluster architecture is 3 master nodes including etcd, 3 infra nodes and 4+ application nodes Red Hat publishes a “sync” container image which runs on the OpenShift cluster to lifecycle cluster components (registry, router, web-console, etc.) Cluster deployment uses “Azure Managed Apps” under the cover, which allows cluster(s) to be deployed in the end customer’s Azure subscription, without the customer being able to modify the clusters, but allowing RH/MSFT access
- JOEY With Azure Red Hat OpenShift, our aim was to simplify the cluster operations so that you focus on building, deploying and scaling apps with confidence. Microsoft and Red Hat manage all the cluster infrastructure, apply security best practices, monitor and operate the VMs. https://azure.microsoft.com/en-us/pricing/details/openshift/ Encryption - By default, there is encryption at rest. The Azure Storage platform automatically encrypts your data before persisting it, and decrypts the data before retrieval. Are master and infrastructure nodes abstracted away as they are with Azure Kubernetes Service (AKS)? No. All resources, including the cluster master, run in your customer subscription. These types of resources are put in a read-only resource group.
- JOEY https://access.redhat.com/documentation/en-us/reference_architectures/2018/html-single/deploying_and_managing_openshift_3.9_on_azure/ All of these capabilities are enabled by containerizing your workloads. This is a precondition of using OpenShift.
- 1) Need to manage lots of infrastructure components For Spring Cloud microservices architecture, establishing technology to do dynamic scaling of infrastructure, is a mountain to climb We have to take care of even service discovery. Lots of things we shouldn't be doing, we have to do it. 2) Difficult to manage app lifecycle "Updating apps has been an issue, mainly because of the monitoring side of stuff." “It is painful to handle things around application lifecycle, like application security, A/B testing.” 3) Difficult to monitor and troubleshoot “Troubleshooting microservices is a pain. Which one is up or down. That is why we are using Hystrix and Zipkin "When we are troubleshooting in production, it is a pain. We do have logs but sometimes we cannot get detailed logs in prod.
- Azure: 1) Build and manage high availability environment to host Spring Cloud middleware - Config, discovery, circuit breaker, tracing, monitoring, app lifecycle 2) Build and manage underlying Kubernetes-based infrastructure to host microservice apps 3) Auto wire up microservice apps with Spring Cloud middleware Customer: 1) Create Azure Spring Cloud instance 2) Upload Java app – Source| JAR
