When choosing between Kubernetes and serverless for a new application, consider these key factors:
- Application Complexity:
- Kubernetes: Great for complex applications with many services and specific needs. It gives you control over your environment but requires more setup and management.
- Serverless: Best for simpler applications or small tasks. It handles the infrastructure for you and is good for event-driven applications.
- Scalability:
- Kubernetes: Can automatically adjust to handle more traffic, but you need to configure it. It’s good for applications with steady or predictable traffic.
- Serverless: Automatically scales up or down based on demand. It’s ideal if your traffic varies a lot or is unpredictable.
- Cost:
- Kubernetes: Often has fixed costs based on the resources you set up, which might be expensive if your usage is low or varies.
- Serverless: You pay only for what you use, which can be cheaper if your usage is variable or low.
- Management:
- Kubernetes: Requires more effort to manage, including updates and security. It’s flexible but needs more maintenance.
- Serverless: Less management needed, as the provider takes care of scaling and infrastructure. It lets you focus on coding.
- Performance:
- Kubernetes: Offers steady performance and lower latency for long-running tasks.
- Serverless: May have some delays when starting up, but is good for short, quick tasks.
Choose Kubernetes for more control and complex needs, and serverless for ease and cost-efficiency with simpler tasks.

To build a recommendation system for a streaming platform, I would adopt a hybrid approach combining collaborative filtering and content-based filtering. Collaborative filtering leverages user behavior, such as ratings and viewing history, to identify patterns and suggest content that similar users enjoyed. Content-based filtering analyzes the attributes of the content (genres, actors, directors) to recommend similar items based on what a user has previously liked.
First, I would gather data on user interactions, including viewing history, ratings, and demographic information. I would preprocess this data to handle missing values and normalize features. Next, I would implement matrix factorization techniques (like Singular Value Decomposition) for collaborative filtering and build a profile for each item using content features for content-based recommendations.
For evaluation, I would use metrics such as Mean Absolute Error (MAE) for prediction accuracy and Precision/Recall at k to assess the relevance of recommended items. Additionally, I would consider the Normalized Discounted Cumulative Gain (NDCG) to evaluate ranking quality. A/B testing with real users could provide further insights into the system’s effectiveness in driving engagement and satisfaction.
