Now let's take a look into the suites that the three big software vendors—Oracle, IBM, and Microsoft—have to offer. You will learn about these suites based on the reference architecture that was described in the previous chapter. There are a number of cross-cutting concerns and additional tools and frameworks that are also part of the suites that were not discussed in the previous chapter. To make a good comparison you will, apart from the building blocks, also learn about:

• Monitoring tools: Once the services are installed in the different building blocks, they need to be monitored. Performance, errors, and load are important aspects you need to keep an eye on.

• Error-handling mechanisms: Errors occur. Especially...
