Loose Coupling and High Cohesion: How To Avoid Tight Coupling and Low Cohesion?

Cohesion is a measure of the number of relationships that parts of a component have with each other.

High cohesion means that : All of the parts that are needed to deliver the component's functionality are included in the component.

Coupling is a measure of the number of... See more

What is Hatchet?

Hatchet replaces difficult to manage legacy queues or pub/sub systems so you can design durable workloads that recover from failure and solve for problems like concurrency , fairness , and rate limiting . Instead of managing your own task queue or pub/sub system, you can use Hatchet to distribute your functions between a set of... See more

More than reading popular books on Design Patterns, two things that helped me write and structure a large codebase better were

reading a lot of good open source codebases (with similar stack)coding and collaborating a lot on the same codebase

I understand the importance of reading general-purpose design patterns, but they might not suit your... See more

Hopefully, at this point, you see where I’m going with this. What I’ve concluded, based on experience, is that positioning your project as an alternative implementation of something is a losing proposition. It doesn’t matter how smart you are. It doesn’t matter how hard you work. The problem is, when you build an alternative implementation, you’ve... See more

Netflix created a scoring system from 0 to 100 that assigns a priority to a request, with 0 being the highest priority and 100 being the lowest priority.

The score was based on 4 dimensions

Functionality - What functionality gets impacted if this request gets throttled? Is it important to the user experience? For example, if logging-related requests... See more

Build & Deployments

Our build process starts by pushing changes to a repository on GitHub. When code is pushed to a repository through a pull request, it triggers a job to build the changes made to the branch and deploy them in isolation. This worklow happens interactively within the pull request, where the author has visibility of all steps.

Some... See more

A single field tells us in plain language what the status of the object is by using enums instead of booleans. Another upside is the extensibility and future-proofing that this technique gives us. If we go back to our previous example of adding a “pause” mechanic,... See more

• Terraform Providers: Terraform is primarily used for defining the infrastructure resources. Its strength lies in its vast collection of providers that offer standardized ways to interact with various cloud services (AWS, Azure, GCP, etc.) and on-premises infrastructure. These providers are essentially plugins that understand the specific APIs and

Problem : Tight coupling leads to fragility - a change in one microservice breaks connected services.

Low cohesion results in unclear responsibilities.

• Solution : Apply loose coupling and high cohesion. In a loosely coupled system, each component is independent and changes in one will not affect the others. High cohesion means that each component
