Microservice Architecture

An introduction of the main concepts of microservice architecture (MSA). We focus on the notion of microservice architecture in connection with “traditional” methods for building a system. Microservice architecture patterns are discussed as well as MSA deployment issues and methods for ensuring required qualities.
Code: ARC-015
Duration: 24 hours


Microservice architecture (MSA) has recently become one of the most popular architectural approaches, because it provides numerous benefits at different stages of the product life cycle. In particular, MSA allows you to improve reaction time when it comes to business requirements.

Yet, in the process of MSA system development, architects face many challenges which often force those who are new to this field to roll back. Some of them include:

  • Errors in decomposition may make the development much more difficult
  • Performance decreases due to serious network delays
  • Distributed data storage prevents us from using transactional consistency
  • A large number of components communicating over the network reduce the system’s reliability
  • It gets difficult to ensure security

Not to mention that testing and maintenance of a distributed system requires additional efforts. This course will help you understand the advantages and disadvantages of MSA so you can decide on the feasibility of using MSA depending on business needs and team capabilities.

We cover the major challenges related to implementing microservice architecture and provide you with strategies, mechanisms, and patterns to solve them. We’ll also be looking at the most popular tools (such as Kubernetes, Istio, Histryx, Kibana, and many others) used in Microservice architecture.


Architectural styles
  • Notion of monolith, SOA, MSA
  • Comparison and selection

MSA decomposition patterns
  • The optimal microservice size
  • Splitting into services by business capabilities
  • Splitting into services by problem domains
  • Domain identification practices
  • Decomposition by technical and organizational aspects

Development organization for MSA
  • Team organization for MSA
  • Code repository organization for MSA

Integration of microservices
  • Communication patterns
  • Synchronous and asynchronous communication mechanisms
  • Orchestration and choreography
  • Main protocols and technologies (REST, gRPC, GraphQL, Kafka, RabbitMQ, etc.)
  • Communication with external systems (API Gateway, BFF)
  • Reactive systems
  • Event-driven architectures
  • Command query segregation

Data handling in MSA
  • Data handling patterns
  • Event sourcing
  • Reference data in MSA
  • Single source of truth in MSA

Main MSA patterns
  • Modifiability. High coupling problem resolution. Versioning of interfaces and events. Types of contracts. Changing event model. Query organization patterns. Microservice chassis. Service mesh
  • Scalability. Load balancers patterns. Discovery services and patterns
  • Performance. Performance patterns in MSA (Bulkheads, Graceful Degradation, etc.)
  • Consistency. Consistency problems in MSA. CAP theorem. Solving consistency problems. Two-phase commits. SAGA Pattern. Decreasing the consistency level
  • Reliability. Fault tolerance mechanisms. Circuit Breaker, Throttling, Dependent Timeouts, and other patterns
  • Security. Security mechanisms in MSA. Authentication. Authorization. Perimeter defense. Communication channel defense. Main protocols and patterns (OAUTH2, JWT, Gatekeeper, Valet Key, etc.)
  • Testability. Testing pyramid and quadrant. Specifics of microservice testing. Unit testing. Integration testing. Component testing. E2E testing. MSA testing patterns.
  • Ease of maintenance. Observability. Observation patterns (distributed tracing, log aggregation, etc.). Monitoring and logging. Microservice configuration. Configuration externalizing. System support
  • Microservice deployment. Deployment pipeline pattern. Deployment patterns. Using Docker and Kubernetes. Using ISTIO mesh. Serverless deployment. Deployment strategies (blue-green, canary, etc.)
  • Strategies of migration from monolith to MSA. Strategies of shifting from monolith to microservices. Strangler monolith. Strangle patterns. Microservice link to monolith. Database migration


  • Provide an overview of MSA and its relationships with other system architectures
  • Provide an overview of designing MSA systems
  • Practice skills of designing MSA systems.
  • Introduce students to the most popular MSA patterns

Target Audience

  • Software Architects
  • DevOps professionals
