What is Microservices Architecture Glossary?
This section breaks down fundamental terms you'll encounter when discussing or working with microservices. Understanding this specific vocabulary is the first step to confidently navigating discussions about this architectural style. The following table provides a Microservices Architecture Glossary with definitions and examples to kickstart your learning.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Microservice | Noun | A small, independent service designed to perform a single business capability. | Our e-commerce platform uses a microservice for handling user authentication. |
| API Gateway | Noun | A server that is the single entry point into the system for all client requests. | The API Gateway routes requests from the mobile app to the appropriate backend services. |
| Service Discovery | Noun | The process of how services locate each other on a network. | With Service Discovery, new instances of a service can be found automatically by other services. |
| Containerization | Noun | Packaging software code and all its dependencies so it can run consistently on any infrastructure. | Containerization tools like Docker help us deploy our microservices quickly and reliably. |
| Orchestration | Noun | The automated arrangement, coordination, and management of complex computer systems and services. | Kubernetes is a popular orchestration platform for managing containerized applications. |
| Scalability | Noun | The ability of a system to handle a growing amount of work by adding resources. | Microservices allow for better scalability as individual services can be scaled independently. |
| Resilience | Noun | The ability of a system to recover quickly from failures. | Building resilience into our microservices means the application can withstand partial outages. |
| Monolith (Monolithic Architecture) | Noun | A traditional software design where all components of an application are a single, indivisible unit. | We are migrating from a monolith to a microservices architecture to improve flexibility. |
| DevOps | Noun | A set of practices that combines software development (Dev) and IT operations (Ops). | DevOps culture encourages collaboration between development and operations teams for faster releases. |
| CI/CD (Continuous Integration/Continuous Delivery/Deployment) | Noun | Practices for frequently and reliably delivering applications by automating the build, test, and deployment processes. | Our CI/CD pipeline automates the deployment of new microservice versions to production. |
| Idempotency | Noun | A property of an operation that means it can be applied multiple times without changing the result beyond the initial application. | Ensuring your API endpoints have idempotency is crucial for reliable distributed systems. |
| Eventual Consistency | Noun | A consistency model in distributed computing that guarantees that if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value. | Some data in our system uses eventual consistency to improve performance and availability. |
| Circuit Breaker | Noun | A design pattern used to detect failures and prevent a cascade of failures in a distributed system. | The circuit breaker pattern helps prevent a single failing service from bringing down the entire application. |
| Distributed Tracing | Noun | A method used to profile and monitor applications, especially those built using a microservices architecture. | Distributed tracing allows us to follow a request as it travels through multiple microservices. |
| Service Mesh | Noun | A dedicated infrastructure layer for handling service-to-service communication, providing features like traffic management, security, and observability. | We implemented a service mesh like Istio to manage communication between our microservices effectively. |

Common Phrases Used
Beyond individual terms, you'll often hear specific phrases related to microservices. Understanding these common expressions will help you follow discussions and contribute more effectively. This section explains some frequently used phrases and their typical contexts, further enhancing your grasp of this technical vocabulary.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Break down the monolith | Refers to the process of decomposing a large, monolithic application into smaller, independent microservices. | The engineering team's main goal this year is to break down the monolith into manageable microservices. |
| Deploy independently | Highlights a key advantage of microservices: each service can be deployed without affecting others. | With microservices, we can deploy independently the payment service without a full system redeployment. |
| Single Responsibility Principle | A design principle stating that a service should do one thing and do it well, focusing on a specific business capability. | Each microservice is designed following the Single Responsibility Principle to ensure it's focused and maintainable. |
| Design for failure | An approach to building systems that anticipates failures and includes mechanisms to handle them gracefully. | When building microservices, it's crucial to design for failure to ensure overall system resilience. |
| Loose coupling | Describes a system where components (services) are independent and have minimal direct knowledge of each other. | Loose coupling between microservices allows us to update or replace them without impacting other parts of the system. |
| Bounded context | A concept from Domain-Driven Design (DDD) that defines the boundaries within which a particular domain model is valid. Often maps to a microservice. | Each microservice typically operates within its own bounded context, managing its specific data and logic. |
| Polyglot persistence | The practice of using different data storage technologies for different microservices, based on their specific needs. | Our system uses polyglot persistence, with some services using SQL databases and others using NoSQL. |
