SOA Exams

The Vendor-Neutral Architecture Approach

In 2009, a coalition of IT authors and enterprise architects gathered in Rotterdam to draft the SOA Manifesto. Led by best-selling author Thomas Erl, the group established that service-oriented architecture (SOA) is a design paradigm, not a technology stack you can buy off the shelf. Erl later founded Arcitura Education, the organization behind the SOA Certified Professional (SOACP) program.

Unlike cloud vendor credentials that test your ability to navigate a specific proprietary console, Arcitura certifications remain strictly vendor-neutral. They evaluate your grasp of universal architectural principles - service autonomy, statelessness, discoverability, and microservice containerization. For IT professionals working in finance, telecommunications, or government sectors with complex legacy infrastructure, these design patterns dictate how distributed systems communicate.

Service orientation peaked as an industry buzzword in the late 2000s, but the underlying mechanics never went away. Modern microservices are a direct evolution of SOA principles. Arcitura's curriculum reflects this continuous evolution, integrating containerization and API management into their service technology modules while retaining the core principles of loose coupling and service abstraction.

The SOACP Modular Structure

Arcitura organizes its certification tracks through a strictly defined modular system. Rather than offering monolithic exams that cover everything at once, the SOACP program breaks knowledge domains into distinct modules. Candidates earn credentials by passing specific combinations of these module exams.

This structure allows candidates to tailor a certification path to specific roles, such as business analyst, security specialist, or lead enterprise architect. You can take individual module exams - usually running 60 to 90 minutes with 40 to 50 questions - or combine them into larger, multi-module exams. The passing score for most individual modules hovers around 70 percent.

Foundational and Technology Exams

Most candidates begin their Arcitura journey with the S90.01: Fundamental SOA Service-Oriented Computing (S90-01A) exam. This baseline module tests your vocabulary and conceptual understanding of service orientation. It covers the shift from monolithic applications to distributed services, explaining how service inventories function and how business logic translates into service capabilities.

Once you understand the theory, the S90.02: SOA Technology Concepts (S90-02A) exam moves into the mechanics. It focuses on the actual transport protocols, messaging frameworks, and API structures that make service-oriented computing possible. You will answer questions about REST, SOAP, XML, and JSON, along with the foundational mechanisms of microservices. The test ensures you understand how data moves between decoupled systems without getting bogged down in the syntax of a specific programming language.

Architecture and Applied Design

Moving from theory to applied engineering requires passing the S90.03: SOA Design Architecture (S90-03A) exam. This test bridges the gap between knowing what a service is and knowing how to build one. It introduces the architectural considerations that differentiate well-designed services from those that fail to meet enterprise goals.

You will face questions on service contract design, versioning, and the specific design patterns required to ensure services remain loosely coupled. The exam tests your ability to position logic as an enterprise resource capable of functioning beyond its initial deployment boundary.

Professionals aiming for senior architect titles eventually face the S90.08: Advanced SOA Design Architecture (S90-08A) exam. Positioned near the top of the SOACP track, this module mixes multiple design layers. It assumes you understand individual service behavior and tests how well you manage service interaction across a full system. The exam deals heavily with runtime governance, design-time versioning, granularity control, and pattern conflicts. You must analyze trade-offs and justify architectural decisions based on enterprise constraints.

Arcitura differentiates its higher-level certifications by requiring practical application. The S90.09: SOA Design Architecture Lab (S90-09A) replaces standard multiple-choice theory with scenario-based testing. During this lab exam, you receive detailed architecture diagrams, service inventory lists, and business requirements. You must identify where two services are too tightly coupled, refactor existing inventories, and apply specific design patterns to resolve scaling issues. You are expected to think like an enterprise architect, evaluating interaction flows and dependency models rather than just selecting a definition from a list.

Career Value for Enterprise Architects

Arcitura certifications hold specific weight in the enterprise architecture job market. While a startup building a fresh application might prioritize a cloud-native developer credential, large enterprises managing hybrid environments look for the architectural maturity that SOACP credentials prove.

Employers in sectors with heavy integration demands use these certifications to identify professionals who can plan systems meant to last decades. The principles tested in these exams - such as reducing implicit dependencies and publishing external dependencies to increase system reliability - apply directly to modern microservice deployments and API gateway management.

A certified SOA professional brings a strategic mindset to system integration. They understand that buying an enterprise service bus or deploying a container orchestration platform does not automatically create a service-oriented environment. By focusing on the design paradigm rather than the tooling, Arcitura certified architects maintain their relevance even as specific software products come and go.
