🕹 Technology AI Serverless Cloud AWS
  1. Think twice before using Lambdas for training ML/AI models due to limitations and complexities.
  2. Serverless infrastructure can be powerful, but choose the right tools for ML tasks, like EC2 instances for training.
  3. Design decisions in the wrong direction can be costly and time-consuming to change, especially in AI and Cloud systems.

Make it resilient: Disaster Recovery Techniques

🕹 Technology Cloud Computing AWS Infrastructure Data Management
  1. There are 4 main disaster recovery techniques: Backup & Restore, Pilot Light, Warm StandBy, and Multi-Site Active/Active.
  2. The techniques aim to optimize for RPO (Recovery Point Objective) and RTO (Recovery Time Objective), which determine how much data loss and downtime are acceptable.
  3. The choice of technique depends on factors like cost, recovery speed, and the criticality of the application, with each method having its own advantages and trade-offs.

🕹 Technology
  1. Scaling a database like MySQL for big companies involves challenges like read and write scalability.
  2. To scale reads, common solutions include using read replicas and Master-Slave replication.
  3. Sharding is a method for achieving horizontal scalability in databases by splitting data into multiple databases, which can introduce complexities but resolves write scalability issues.

🕹 Technology DevOps Cloud Computing AWS Infrastructure
  1. Autoscaling allows you to adjust resources automatically based on traffic, ensuring your application stays performant and resilient.
  2. Auto Scaling Groups in AWS help manage resources by defining minimum, desired, and maximum instances, allowing for easy scaling up and down.
  3. AWS Auto Scaling Groups provide strategies like simple scaling, target scaling, and step scaling to optimize costs and react to traffic based on predefined metrics.

DevOps Concepts #1: Load Balancing Algorithms

🕹 Technology DevOps Algorithms Networking
  1. Load balancing is important for distributing traffic across servers.
  2. Stateless services are preferred over stateful ones for easier scaling.
  3. Different load balancing algorithms like Round Robin, Weighted Round Robin, Least Connections, and Least Time offer various ways to distribute traffic efficiently.
