• MySQL database for data storage and retrieval

The .Net framework is a powerful tool for developing microservices using Web APIs.

• The .Net framework provides a set of libraries and tools for building scalable and reliable microservices.

• Web APIs in .Net allow for easy communication between different services and clients.

• Features like dependency injection and middleware in .Net make it easier to develop and maintain microservices.

• Examples of popular frameworks for bui...read more

To troubleshoot a network bottleneck in a web API application hosted in a public cloud like Azure or AWS, one can analyze network traffic, monitor server performance, and optimize resource allocation.

• Use network monitoring tools to analyze traffic patterns and identify potential bottlenecks.

• Monitor server performance metrics such as CPU usage, memory usage, and disk I/O to pinpoint any resource constraints.

• Optimize res...read more

Azure Service Fabric clusters are used to deploy and manage microservices-based applications on Microsoft Azure.

• Azure Service Fabric clusters provide a platform for deploying and managing scalable and reliable microservices.

• They offer automatic scaling, rolling upgrades, and health monitoring for microservices.

• Service Fabric clusters can be used to deploy stateless or stateful microservices.

• They support multiple progra...read more

REST is lightweight and flexible, while SOAP is more structured and standardized.

• REST uses HTTP methods for communication, while SOAP uses XML messaging.

• REST is better suited for mobile and web applications, while SOAP is better for enterprise-level applications.

• REST is stateless, while SOAP can maintain state between requests.

• REST is easier to implement and understand, while SOAP has a steep learning curve.

• REST is mor

The architecture of the project is based on microservices with a containerized approach using Docker and Kubernetes.

• Utilizes microservices architecture for scalability and flexibility

• Containerized approach using Docker for easy deployment and management

• Orchestrated with Kubernetes for automated scaling and monitoring

To check if a number is a power of 2, we can use bitwise operations.

• A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.

• If n is a power of 2, then n & (n-1) will be 0.

• For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.

Sort a stack without using another data structure

• Use recursion to pop the top element and insert it at the bottom of the remaining stack

• Repeat until the stack is sorted in ascending order

• Time complexity: O(n^2), space complexity: O(n) due to recursion

Check if array has continuous increasing and decreasing values

• Loop through the array and check if each element is greater than the previous one

• Once you find the maximum element, check if the remaining elements are in decreasing order

• If yes, return true else false

Design a cricinfo (LLD)

• Identify the entities: players, teams, matches, scorecards, tournaments, etc.

• Define the relationships between entities

• Create a database schema to store the data

• Implement APIs to fetch and update data

• Design a UI to display the information

• Consider scalability and performance

• Ensure data security and privacy
