YOU CAN’T BUILD SOMETHING UNLESS YOU UNDERSTAND THE ARCHITECT.
Understanding architecture is very important for a cloud engineer. Monolithic architecture, tier architecture, and microservice architecture are three different approaches to designing software applications.
Monolithic architecture is a traditional approach where the entire application is built as a single, self-contained unit. All components and functionality of the application are tightly coupled and run as a single process. This means that if any component fails, the entire application can go down. Monolithic architecture is relatively simple to develop and deploy, but it can be difficult to scale and maintain over time.
Tier architecture, also known as multi-tier architecture, is a more modern approach that breaks the application into separate tiers or layers. Each tier is responsible for a specific aspect of the application, such as presentation, logic, or data storage. Communication between tiers is typically done through well-defined interfaces or APIs. This approach provides more flexibility and scalability, as each tier can be developed and maintained independently. It also allows for better fault tolerance, as failure of one tier does not necessarily bring down the entire application.
Microservice architecture is a more recent approach that builds applications as a collection of small, independent services. Each service is responsible for a specific business capability and can be developed and deployed independently. Communication between services is typically done through lightweight protocols such as HTTP or REST. Microservice architecture provides greater flexibility, scalability, and fault tolerance than monolithic or tier architectures, but it can also be more complex to design and maintain.
The main difference between monolithic architecture and tier architecture is that monolithic architecture involves building the entire application as a single unit, while tier architecture involves breaking the application into separate tiers or layers. Microservice architecture takes this a step further by building the application as a collection of small, independent services. Each approach has its own advantages and disadvantages, and the choice of architecture depends on the specific needs of the application and the organization.
