Basics of Cache3:10
Learn caching fundamentals and why it matters for memcached apps. Cache stores frequently accessed data in a faster location to improve data access, latency, responsiveness, bandwidth, and scalability.
Types of Cache3:04
Explore page, object, and database caching to optimize web app performance and learn how cdn, browser, and session caches deliver content faster at edge locations.

Introduction to Memcached2:58
Cache data quickly with Memcached, a fast distributed memory caching system that alleviates database load by storing data in memory for access using a simple key-value interface and scalable architecture.
Installation of Memcached2:53
Install Memcached to accelerate caching and improve the performance and scalability of applications, aligning with the course goal of building faster, more scalable apps.
Memcached - Configurations and settings1:47
Master memcached configurations to tune port, memory allocation, connections, verbose mode, and daemonization using the memcached.conf or memcached.ini file, with Linux commands to stop, update, and restart the service.
Data model - Key value pairs3:48
Memcache's data model is built on key value pairs, using unique keys to store and retrieve values with optional expiration, delivering simple, flexible, and efficient caching for scalable apps.
Cache expiration and eviction3:55
Explore cache expiration and eviction in memcache to keep data fresh and the cache responsive by setting expiration times and applying the least recently used policy.

What is distributed caching?2:01
Discover how distributed caching speeds apps by storing accessed data across multiple nodes, forming a cache cluster that replicates or partitions data to reduce latency and offload back end databases.
Distributed caching with memcached3:40
Explore distributed caching with Memcached to boost performance and scalability through in-memory storage, a simple key-value store, time to live, and automatic load balancing across nodes.
Consistent Hashing3:54
Explore consistent hashing principles for scalable, fault-tolerant distributed caching with memcache, including hash rings, virtual nodes, load balancing, and balanced data distribution.
Scaling Memcached2:34
Scale memcached to meet growing workloads using vertical and horizontal scaling in distributed caching environments, with sharding and consistent hashing to distribute workloads effectively.

Tools to monitor and analyze Memcached performance3:11
Discover tools to monitor Memcached performance, including stats, Memcache tools, Munin, Prometheus and Grafana, and Memcache Stop, while weighing ease of use, metrics, and security considerations.
Optimize memcached for performance4:01
Understand workload and allocate memory to optimize memcache for peak performance. Tune eviction policies, configure key and value limits, and minimize latency with network optimization, compression, and monitoring.

Usecase 1: Netflix like video delivery system3:16
Explore how memcache powers a Netflix-like video delivery system by caching video segments, metadata, and sessions to reduce latency, enhance scalability, and smooth playback across devices.
Usecase 2: Amazon like E-Commerce system2:40
Learn how memcache accelerates an amazon-like ecommerce system by caching product details, prices, inventory, shopping carts, and sessions, using a distributed memcached cluster to boost throughput and reduce database load.

Troubleshoot common issues with Memcached3:37
Troubleshoot common memcache issues by inspecting configuration files, port conflicts, and memory allocation, then apply step-by-step fixes to restore memcached reliability.
Best practices and Guidelines4:08
Explore best practices for deploying memcache to boost speed and scalability, including cache key design, expiration strategies, scaling, and monitoring.
Security best practices and recommendations4:28
Implement security best practices for memcached by changing the default port and bind address to restrict access, enabling SASL and SSL/TLS, limiting memory and item size, and applying timely updates.

Requirements

Prior knowledge of web application especially back-end systems. Experience in Python/PHP/Java programming

Description

In today’s data-driven world, application speed and scalability are critical to user satisfaction and business success. Memcached Fundamentals: Build Faster and More Scalable Apps is designed to help developers, system administrators, and architects master one of the most powerful in-memory caching systems used by top tech companies worldwide.

You’ll begin by understanding the core principles of caching, why it’s essential for modern applications, and how it improves performance. The course then dives into Memcached, exploring its installation, configuration, and key-value data model. You’ll learn how to manage cache expiration, eviction policies, and configurations to ensure efficient memory usage.

Through hands-on sessions, you’ll explore distributed caching concepts such as consistent hashing and scaling strategies for high-traffic systems. Performance tuning techniques and monitoring tools are covered to help you optimize Memcached for real-world workloads.

To connect theory with practice, you’ll analyze real-world use cases such as Netflix-style video streaming and Amazon-like e-commerce systems that rely on caching for lightning-fast performance. The course concludes with troubleshooting techniques, security best practices, and optimization guidelines to make your deployments robust and production-ready.

By the end of this course, you’ll have the knowledge and confidence to implement Memcached in your own applications, improving performance, reducing database load, and creating a seamless user experience.
