Microservices Architecture Test

The Microservices Architecture Test is a free advanced-level, 25-minute skill test from Science of Apps. It tests microservices architecture — when to choose microservices over a monolith, decomposing by business capability and bounded context, synchronous and event-driven communication, data ownership and sagas, deployment on containers and Kubernetes, and resilience, security and observability. Score 70% or more on its 25 questions to earn a verifiable Microservices Architecture certificate (SOA-MICA). Every question is based on published standards and research — including Microservice architecture patterns (Chris Richardson), Microservices (James Lewis and Martin Fowler), Cloud Design Patterns (Microsoft Azure Architecture Center) — and each answer is explained with its source.

Read the five skill areas on this page, then take the 25-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Microservices Architecture certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Microservice architecture patterns (Chris Richardson); Microservices (James Lewis and Martin Fowler); Cloud Design Patterns (Microsoft Azure Architecture Center); Site Reliability Engineering (Google); Kubernetes concepts (kubernetes.io (CNCF)); OWASP Cheat Sheet Series (OWASP). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Principles and Decomposition (Monolith versus microservices, Bounded contexts and Service boundaries); Communication and APIs (Synchronous calls, Asynchronous messaging and API gateways and contracts); Data Management (Database per service, Sagas and Querying across services); Deployment and Platform (Containers and Kubernetes, CI/CD and Configuration); Resilience, Security and Observability (Fault tolerance, Service-to-service security and Distributed tracing and monitoring). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

Software architect, Senior backend engineer, Platform engineer, DevOps engineer and Engineering lead. It suits anyone who wants a quick, verifiable way to show Microservices Architecture skills, from students and career switchers to experienced professionals.

Yes. The Microservices Architecture Test is free and covers all of these: 25 scenario questions in 25 minutes, each answer explained with the source it comes from, so it works as interview and exam practice. It isn't a full course, so use the areas you miss as your study list. Scoring 70% or more earns a verifiable certificate.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
