For my “aspiring” Cloud folk who have heard about https://t.co/1gPZPVnFqD seriously..

What’s preventing you from focusing for a minimum of 6 months to get the hard technical skills you NEED.

I really want to know, what are your blockers?

And For those just hearing about this resource.. 2025 is the year you dial in!

The 9 Algorithms That Dominate Our World

[Bytebytego @bytebytego]

How to scale a website to support millions of users? We will explain this step-by-step.

The diagram below illustrates the evolution of a simplified eCommerce website. It goes from a monolithic design on one single server, to a service-oriented/microservice architecture.

Suppose we have two services: inventory service (handles product descriptions and inventory management) and user service (handles user information, registration, login, etc.).

Step 1 - With the growth of the user base, one single application server cannot handle the traffic anymore. We put the application server and the database server into two separate servers.

Step 2 - The business continues to grow, and a single application server is no longer enough. So we deploy a cluster of application servers.

Step 3 - Now the incoming requests have to be routed to multiple application servers, how can we ensure each application server gets an even load? The load balancer handles this nicely.

Step 4 - With the business continuing to grow, the database might become the bottleneck. To mitigate this, we separate reads and writes in a way that frequent read queries go to read replicas. With this setup, the throughput for the database writes can be greatly increased.

Step 5 - Suppose the business continues to grow. One single database cannot handle the load on both the inventory table and user table. We have a few options:

1. Vertical partition. Adding more power (CPU, RAM, etc.) to the database server. It has a hard limit.
2. Horizontal partition by adding more database servers.
3. Adding a caching layer to offload read requests.

Step 6 - Now we can modularize the functions into different services. The architecture becomes service-oriented / microservice.

Question: what else do we need to support an e-commerce website at Amazon’s scale?

11 am I side chat a guy for a Laravel role he posted, 3 pm I am invited for an interview, He moves ahead to ask me I build a fully responsive platform as an unpaid intern and then I will be considered for a paid role!

@softwareEngke I 100% agree. Everything seems to be broken at the moment. We just need mentors to help us grow and not frameworks!

Billing in a setting like a hospital can be hectic. You can have an invoice with items like drugs, consultations, therapy, beds among others. In a typical world this calls for multiple tables in the database but with Laravel, we have polymorphic relationships....

[Njuguna @__hostDes]

You won’t find a better-crafted framework out there than Laravel

[SumitM @SumitM_X]

As a backend engineer.

Please learn:

- System Design (scalability, microservices)

-APIs (REST, GraphQL, gRPC)

-Database Systems (SQL, NoSQL)

-Distributed Systems (consistency, replication)

-Caching (Redis, Memcached)

-Security (OAuth2, JWT, encryption)

-DevOps (CI/CD, Docker, Kubernetes)

-Performance Optimization (profiling, load balancing)

-Cloud Services (AWS, GCP, Azure)
