A Look Inside Docker & Its working.
Docker is a tool to run containers and build images, providing a CLI and API for container management. Containers are isolated entities that include applications and their dependencies. Docker images define container contents and operation. The Docker CLI translates commands into API requests for the Docker daemon, which manages container and image operations via ContainerD and runc. Key Linux features, Namespaces and C-Groups, provide process isolation and resource allocation within containers.

Kubernetes Best Practices I Wish I Had Known Before
Kubernetes has revolutionized the building, shipping, and running of applications, but adopting best practices can save time, money, and headaches. Key recommendations include setting resource requests and limits, using namespaces for organization, avoiding multi-container pods unless necessary, using package managers for YAML files, implementing ingress and networking best practices, and setting up proper monitoring and security measures. Additionally, it's important to automate deployments with CI/CD, keep the cluster updated, and use labels and annotations wisely. Adopting a multi-environment approach, optimizing container images, and following a reliable logging strategy further enhance efficiency and reliability.

Scaling Monoliths: A Practical Guide for Growing Systems
Scaling monoliths can be achieved through various strategies such as vertical scaling, horizontal scaling, database scaling, caching, and using message queues. Vertical scaling involves adding more resources to a single machine, while horizontal scaling involves running multiple instances behind a load balancer. Database scaling can be done using read replicas, materialized views, and database sharding. Effective caching can reduce database load, and message queues can help manage traffic spikes by deferring heavy tasks. The key is to implement the right solution based on specific bottlenecks and system requirements.
