The Oracle Private Cloud Appliance (PCA) has emerged as the premier platform for running WebLogic and other middleware and application tier software. This is especially seen with Oracle Fusion Middleware, often in conjunction with Oracle Exadata - the premier database platform.
There are several reasons why this has proven so effective.
- Private Cloud Appliance provides quick time to value for a robust virtualization platform, going from power-up to starting VMs in a matter of hours. The Private Cloud Appliance automates discovery and provisioning of physical infrastructure.
- Private Cloud Appliance provides high performance high speed 100Gb Ethernet, ZFS storage array, and X8-2 compute nodes.
- Private Cloud Appliance design avoids single points of failure on management, network, storage, and compute resource, and permits 'zero-downtime' rolling upgrades to system infrastructure.
- Prebuilt Oracle VM virtual appliances and templates quickly stand up application instances. This is complementary to Private Cloud Appliance quickly and automatically standing up physical infrastructure. You can see a list of virtual appliances at https://www.oracle.com/virtualization/technologies/virtual-appliances.html
- High performance inter-VM networking using the Private Cloud Appliance internal networks permits low-latency, high bandwidth, private communication between VMs in a clustered application. This is especially useful for applications like WebLogic and Coherence.
- Private Cloud Appliance provides load balancing (Dynamic Resource Scheduling - DRS) and High Availability (HA) features that provide higher performance and automates recovery from outage.
- Private Cloud Appliance can provide Infrastructure as a Service (IaaS) cloud function via Oracle Enterprise Manager 13c.
- Application orchestration and automated workload deployment can be performed with Ansible or the Oracle VM API
- Customers can use Trusted Partitioning to manage software license costs.
