Happy Birthday Sir.Questions I faced in Interview, Could you please answer these question that will be really helpful. 1. There is a scheduler that runs every thursday to import data from CSV file in FTP server to User table. CSV file will contain new user or updates to existing user or existing user deleted. There is no flag in csv file to identify whether it new or existing or removed. How do you design a system to import file to table with less I/O. 2. we have service which calls multiple different API, If any one api call fails how do you make sure other API calls are not committed ? 3. What is clean architecture and when do you use it? 4. What is CQRS design pattern and why we need to use? 5. There is an application which is running in Dev and QA environment, How to configure authentication for this application such that Dev environment uses AD authentication and QA environment uses Forms Authentication or any other authentication.? 6. What is Repository pattern and Unit of Work why do we need to use it? 7. Entity Framework VS Dapper which one do you choose for your project and why? 8. Can we have EDMX file and Code First approach in same project? 9. Difference between Adapter and Decorator pattern? 10. How do you plan and migrate the existing application to Azure Cloud? 11. Azure App service vs Azure Function
We have taken the questions and will try to attempt it in later chapters. Thanks for commenting

You are a good teacher love from pakistan.
57:00 I was hired for tech lead(Individual Contirbutor role) but giving Technical Architect (Individual Contributor role). I dont have any experience with Architect role but willing to learn and looking for some guidance.
Very nice to hear that. but many times ( especially in smaller companies) architects are taken and made to code :-) like developers.
Hi Sir, I got question related to Adopter , Bridge and Façade Pattern and They asked me its all wrapper then why do need all these ? If you can explain about it more ?
Bridge and Facade surely do not look like wrappers but Adapter does come does have some resemblance . But please note its not just about creating a wrapper the whole point is to make incompatible interface compatible. And Adapter has two flavors Object adapter and other class adapter. Object adapter looks like a wrapper but not class adapter as it uses inheritance. And please note Adapter pattern adheres to interface but a normal wrapper class is just a aggregation.
😊
Happy Birthday sir
Thank You :) there is a free gift mentioned in the video do not miss to claim it. Happy Learning Happy Job Hunting.
Happy birthday 🎂 sir
Thank You for your wishes :)
for 52:00 if we remove null check inside lock then also it will be a lazy loading and it entered here because it is null in first condition. in between how it can become null
Buddy, it will create a performance issue if you don't have an outer null check. More thread, try to acquire for lock.
I was asked basic method to write in architecture interview.. interviewer was looking how I write code not the logic
I got a question about observer pattern
Happy Birthday Shivji
Thank You So Much :)
You are a good actor also😂😂
Dependency Injection is design pattern. Dependency inversion is architechture pattern. Inversion of control is architechture style. Please correct me
Yes , DI is a pattern yes or must be to be more specific constructor injections ,, property DI injection . I think one more keyword we should add here design principle. DINV and IOC are Design principle.
design principles guide the design of individual components, ensuring they are well-organized and adhere to best practices. On the other hand, architecture styles guide the overall structure of the entire software system, determining how different components and modules interact at a higher level. While design principles are concerned with the "how" of designing individual parts, architecture styles focus on the "what" and "how" of organizing and structuring the entire system.
You are frutfull.
😂 yes answered singleton pattern

Good teaching methology 👍🤟
