Tight coupling refers to a situation where two or more components in a system are highly dependent on each other, meaning that changes made to one component will have a significant impact on the others. This can create a number of problems, including decreased system flexibility, increased complexity, and difficulty scaling the system.
In the context of AWS, tight coupling often refers to a situation where application code is tightly coupled with the underlying infrastructure, such as the servers or databases that the application is running on. This can make it difficult to scale the application or make changes to the infrastructure without also making changes to the application code.
Decoupling, on the other hand, refers to a design approach where components in a system are designed to be more independent of each other, meaning that changes made to one component will have minimal impact on the others. This can lead to increased system flexibility, decreased complexity, and easier scaling.
In the context of AWS, decoupling often involves breaking up applications into smaller, more modular components that can be managed and scaled independently of each other. This is often achieved through the use of microservices architecture, where each service is responsible for a specific task or set of tasks.
Let's take an example of a traditional monolithic application that is tightly coupled. In this application, the web server, application server, and database are all running on the same server. If you need to scale the application to handle more traffic, you would need to scale the entire server, which can be costly and inefficient. Additionally, if you need to update the database or make changes to the server configuration, you would need to make changes to the application code as well.
Now let's consider a decoupled architecture using microservices. In this architecture, the application is broken up into smaller, independent services, such as a web server, an application server, and a database. Each service can be managed and scaled independently of the others, making it easier to scale the application and make changes to the infrastructure without impacting the application code.
For example, let's say you need to update the database to a newer version. In a tightly coupled architecture, this would require changes to the application code to ensure compatibility with the new database. In a decoupled architecture, however, you can update the database independently of the other services, without needing to make any changes to the application code.
