Software as a Service (SaaS) is fast becoming the deployment du jour, but appliances haven’t lost favor yet. The decision over an on-premise install or appliance versus an SaaS solution should still be made on a case-by-case basis. IBM Cast Iron offers both options and each enables cloud-to-cloud, cloud-to-on-premise and on-premise-to-on-premise integration and real-time, near-real-time and batch.
Here’s a brief look at both options.
Cast Iron As Appliance
Cast Iron can be deployed as either physical hardware or a virtual machine. With this style of deployment, the Integration Appliance is installed on-premise – normally behind the firewall, but not within a DMZ.
The runtime environments for the dev, test and prod lifecycles are typically separated, each with its own Integration Appliance to access necessary endpoints within the environment.
The user maintains full control of projects and their orchestrations on the appliance through the WMC. The orchestrations are started through activities which include polling, scheduling or an incoming request – an HTTP Receive Request, for example. Data flows through the Integration Appliance and is stored internally as XML variables. Users control the logging for each orchestration.
Cast Iron Live
This multi-tenant, browser-accessed deployment model includes key components for users to design, run and manage integrations all in the cloud. Those components are:
- A clustered runtime engine that runs the integrations with built-in fault-tolerance and recovery mechanisms
- A multi-tenant, highly available system to store the designed integrations
- A load-balancer to intelligently manage the loads throughout the various runtime engines
- Highly available file systems to store and manage logs that are related to the integrations
The Live version also includes a Design environment with the same capabilities as the on-premise Studio environment
