If upgrading ECE, read upgrade your installation for guidance.

To prepare your hosts for their ECE installation, the following prerequisites must be met:

Best practices and recommendations

edit

To prepare your hosts for ECE installation, the following best practices are recommended and should be considered:

High availability - For production and mission-critical systems, high availability must be considered
Separation of roles - To group components on ECE and prevent conflicting workloads, consider role separation
Load balancers - Using a load balancer is strongly recommended
JVM heap sizes - Configure the proper JVM heap size based on your use cases
Wildcard DNS record - Configure your own wildcard DNS record for production systems
Manage installation capacity - Configure your memory, CPU quotas, processors and storage properly
