What is Monolithic Architecture Glossary?
This section of our Monolithic Architecture Glossary delves into the core vocabulary you'll encounter when discussing this specific type of system design. Understanding these fundamental terms is the first step to discussing monolithic systems, their benefits, and drawbacks within software architecture. This Monolithic Architecture Glossary aims to simplify complex concepts, aiding your language learning journey especially if you encounter pronunciation problems with new terms.
Below is a table listing essential words and phrases related to monolithic architecture. Each term includes its part of speech, a simple definition, and an example sentence to help you understand its usage in context.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Monolith | noun | A single, large, self-contained software application where all components are bundled together. | The team decided to build the initial version as a monolith for simplicity. |
| Coupling | noun | The degree of interdependence between software modules or components. | Tight coupling in a monolith means changes in one module can affect others. |
| Scalability | noun | The ability of a system to handle an increasing amount of work or traffic. | Scalability can become a challenge for large monolithic applications under heavy load. |
| Deployment | noun | The process of making a software application available for use. | Deployment of a monolith typically involves updating the entire application at once. |
| Module | noun | A distinct, self-contained unit of functionality within a software system. | In a monolith, different modules like user management and payment processing are tightly integrated. |
| Legacy System | noun | An old method, technology, computer system, or application program. | Migrating a legacy system built as a monolith requires careful planning. |
| Single Codebase | noun phrase | All the source code for an application is stored in one central repository or project. | A single codebase is characteristic of monolithic architecture. |
| Tightly Coupled | adjective phrase | Describes components that are highly dependent on each other. | Tightly coupled systems can be harder to modify and scale independently. |
| Scalability Bottleneck | noun phrase | A component or resource that limits the system's ability to scale further. | Identifying the scalability bottleneck in a monolith is crucial for performance. |
| Refactoring | verb | The process of restructuring existing computer code without changing its external behavior. | Refactoring a large monolith can improve its maintainability and structure. |
| Application Stack | noun phrase | The set of technologies (e.g., operating system, database, programming language) used to build and run an application. | The entire application stack for a monolith is usually consistent across all its parts. |
| Single Point of Failure | noun phrase | A part of a system that, if it fails, will stop the entire system from working. | In a monolith, a critical bug in one module can become a single point of failure. |
| Development Velocity | noun phrase | The speed at which a development team can produce working software. | Large, complex monoliths can sometimes slow down development velocity due to interdependencies. |
| Technology Stack Lock-in | noun phrase | Difficulty in adopting new technologies because the entire application is built with a specific, unified stack. | One potential downside of a monolith is technology stack lock-in. |
| Inter-module Communication | noun phrase | The way different functional units or modules within the application exchange information. | In a monolith, inter-module communication often happens via direct function calls within the same process. |

Common Phrases Used
Beyond individual words, there are common phrases and idioms used when discussing monolithic architecture. Understanding these expressions will help you follow conversations and technical discussions more effectively. This section covers some frequently used phrases, explaining their meaning and providing context through examples. Recognizing these can help avoid language learning errors in technical discussions.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| "Scaling out" vs. "Scaling up" | Used to describe two different strategies for increasing system capacity. "Scaling out" means adding more machines; "scaling up" means increasing resources on existing machines. | For our monolith, "scaling up" the server hardware was the initial approach before considering "scaling out." |
| "Big Ball of Mud" | A colloquial, often negative term describing a software system (frequently a monolith) that lacks a clear, discernible architecture and is difficult to maintain. | Without careful design and refactoring, a monolith can evolve into a "Big Ball of Mud." |
| "Lift and Shift" | A migration strategy where an application is moved from one environment to another (e.g., on-premises to cloud) with minimal or no changes to its core architecture. | The company decided to "lift and shift" its legacy monolith to the cloud to reduce infrastructure costs. |
| "Strangler Fig Pattern" | An architectural pattern for incrementally replacing parts of a monolithic application with new services, gradually "strangling" the old system. Learn more about this pattern. | We are using the "Strangler Fig Pattern" to modernize our monolithic application piece by piece. |
| "Technical Debt" | The implied cost of rework caused by choosing an easy (limited) solution now instead of using a better approach that would take longer. Monoliths can accumulate this over time. | Years of quick fixes in the monolith have led to significant "technical debt." |
| "Single Deployment Unit" | Describes how the entire monolithic application is packaged and deployed as one complete unit. | A key characteristic and sometimes a challenge of a monolith is that it’s a "single deployment unit." |
| "Monolithic Hell" | A term used to describe the state where a monolithic application has become so large and complex that it's extremely difficult to maintain, scale, or update. | The team was struggling with "monolithic hell" due to the sheer size and complexity of the codebase. |
