CIOs, developers, and business users see SOA (and its effectiveness) differently.
Advantages of SOA:
the ability to quickly adapt IT to changing business challenges;
incentive for analysis and optimization of the company's business processes;
the ability to ensure integration during the consolidation of companies (= systems);
the ability to reduce the TCO of systems.
SOA Features:
long-term complex projects;
rethinking the IT strategy of the enterprise as a whole.
However
the SOA project should solve the tasks not of the IT department, but of the business as a whole;
often the result of SOA is a beautiful infrastructure, but not a real business value.
so decide for yourself
