What’s needed to put Kubernetes into production?
Enterprise Linux
Cluster services
monitoring,
showback, registry,
logging
Application services
middleware, functions, ISV
Service mesh
Developer services
dev tools, automated
builds, CI/CD, IDE
Automated operations
certified
Lacks many essential components
1. Operating system
2. Developer tooling and UX
3. Container runtime (CRI-O, Containerd, Docker,
etc).
4. Image registry
5. Software-defined networking
6. Load‐balancer and routing
7. Log management
8. Container metrics and monitoring
9. DNS
10. Ingress
11. RBAC

The customer (or third-party) must configure,
integrate, operate and support additional
components to be fully operational.

What's new in OpenShift 4.6
Connectivity mode
- Allows developers to focus on the
composition of their application, both on
how it’s managed as well as how things are
connected.
Parity between List & Graphical
- Display Options
- Filters
- Find
Admin’s Project-> Workload tab has
an increased feature set
Consumption mode
- Allows developers to focus solely on
components consuming resources.
- Thus, no connectors are shown (Service
Binding, Visual, Traffic, Triggers, etc), nor
groupings. Pod count is shown by default.
Application topology

Monitor your applications with ease!
● Improved discoverability of alerts in topology
and Monitoring
● Easy access to Alert Details
● Alerts tab allows users to view application alerts
& silence them as as needed
● Monitoring your sample application Quick Start
available to show users how to access basic
monitoring features

Application Monitoring & Troubleshooting

Abstract Fluentd configuration by introduce new log
forwarding API to improve support and experience
for customers.
● Introduce a new, cluster-wide ClusterLogForwarder CRD (API)
that replaces needs to configure log forwarding via Fluentd
ConfigMap.
● The API helps to reduce probability to misconfigure Fluentd
and helps bringing in more stability into the Logging stack.
● Features include: Audit log collection and forwarding, Kafka
support, namespace- and source-based routing, tagging, as
well as improvements to the existing log forwarding features
(e.g. syslog RFC5424 support).
● WARNING: We will not automagically migrate old Tech
Preview CRs into a GA CR.
