Executive SummaryUpdated on Mar 5, 2025

Oracle SOA Suite and IIS compete in the enterprise application integration and web hosting categories, respectively. Oracle SOA Suite appears to have the upper hand in integration capabilities, while IIS excels in user-friendliness and cost-effectiveness.

Features: Oracle SOA Suite offers integration with a wide range of systems using technology adapters, service orchestration capabilities, and comprehensive scalability tools. It supports complex integration scenarios leveraging its strong fault tolerance. IIS, on the other hand, is a lightweight web server ideal for web application hosting, with simple setup and strong integration with Microsoft products, offering stability and native support for Windows.

Room for Improvement: Oracle SOA Suite needs improved error handling, better support for micro-services, and enhanced integration with Enterprise Manager. Its user interface and configuration processes also require simplification. IIS faces challenges in integrating with non-Microsoft products, and enhancements are needed in documentation, security features, and cluster management for better usability.

Ease of Deployment and Customer Service: Oracle SOA Suite predominantly supports on-premises deployments, requiring significant expertise for management. Customer service reviews are mixed, citing slow and inconsistent support. IIS supports both on-premises and cloud deployments, with straightforward installation via Windows Server. It is generally praised for deployment ease, although customer support quality varies.

Pricing and ROI: Oracle SOA Suite is considered expensive, with high licensing fees and resource demands, suitable for larger enterprises needing complex integration. Careful cost management is essential to ensure ROI. IIS is cost-effective, bundled with Windows Server licenses, thus offering excellent ROI for those already using Microsoft infrastructure.

Room For Improvement

IIS struggles with compatibility, security, usability, and integration issues, inconsistent performance, costly licensing, and limited technical support.

Oracle SOA Suite needs performance, stability, integration, mobile support improvements, and simpler deployment, with concerns over cloud capabilities and costs.

It's influenced by the server's service performance.

Ibrahim Sherif

IT System Administrator at Bouri

It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.

Krishnakumar Natarajan

Oracle SOA Suite licensing cost tends to be higher, adhering to a fixed pricing model rather than a pay-per-use basis, which might not be suitable for smaller organizations.

Setup Cost

Enterprise users find IIS cost-effective within Windows but some see high licensing fees compared to Linux alternatives.

Oracle SOA Suite's cost is influenced by setup, licensing, and cloud options, with high availability justifying enterprise expenses.

If you have a Windows license, there is no additional cost for IIS.

Ibrahim Sherif

IT System Administrator at Bouri

We never had any pricing issue, but I don't know if it is competitive or not.

Krishnakumar Natarajan

Systems Engineer at Atos

Designs and manages multiple websites while ensuring data backup and disaster recovery

I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Has enabled complex data flow management but faces limitations with modern integration needs

There are areas of Oracle SOA Suite I would like to see improved or enhanced in the future, particularly regarding its adapter capabilities. The popularity of Oracle Integration Cloud nowadays arises from its larger set of adapter capabilities, including numerous application adapters. In contrast, Oracle SOA Suite provides a limited number of adapters. I would like to see more REST-based features added to Oracle SOA Suite, currently lacking, along with an enhancement of file size or payload capability, as the existing limitation is a 10 MB payload size. Additionally, Oracle SOA Suite licensing cost tends to be higher, adhering to a fixed pricing model rather than a pay-per-use basis, which might not be suitable for smaller organizations.

SOA Suite

Overview

Internet Information Services (IIS) provides a secure, easy-to-manage, modular and extensible platform for reliably hosting websites, services and applications. With IIS, you get choice and control without giving up reliability or security.

Microsoft

Oracle SOA Suite is a comprehensive, standards-based software suite to build, deploy and manage integration following the concepts of service-oriented architecture (SOA). The components of the suite benefit from consistent tooling, a single deployment and management model, end-to-end security and unified metadata management. Oracle SOA Suite helps businesses lower costs by allowing maximum re-use of existing IT investments and assets, regardless of the environment (OS, application server, etc.) they run in, or the technology they were built upon. Its easy-to-use, re-use focused, unified application development tooling and end-to-end lifecycle management support further reduces development and maintenance cost and complexity.
