Instagram 📱 Architecture


Instagram, boasting over 2 billion users, is a powerhouse of innovation, and its success hinges on a robust and scalable architecture. Let's explore some key components:

Microservices Architecture: Instagram leverages microservices for independent, modular development. This enables flexible scaling of individual components based on demand.

Global Content Delivery Network (CDN): A robust CDN ensures fast and reliable content delivery for users worldwide. Caching frequently accessed data at geographically distributed edge locations minimizes latency and improves user experience.

Tech Stack Powerhouse: Instagram utilizes a diverse mix of technologies to handle various tasks:

Frontend: React (UI framework), GraphQL (API querying), Native mobile development with Swift (iOS) and Kotlin (Android)
Backend: Django (web framework), Gunicorn (web server)
Data Storage: Memcached (in-memory caching), PostgreSQL (relational database), Cassandra (NoSQL database for high-volume data), CockroachDB (distributed SQL database for scalability)
Messaging/Streaming: Apache Kafka (distributed streaming platform), Scuba (Facebook-developed messaging system)
Data Processing: Spark (large-scale data processing), Presto (ad-hoc SQL querying), Scuba (for internal data pipelines)
DevOps: Kubernetes (container orchestration), Docker (containerisation), ELK Stack (log management), Prometheus (monitoring)

As a DevOps engineer, every day brings a unique blend of challenges and opportunities to drive innovation while ensuring the stability of our systems.Here’s a glimpse into what a typical day looks like

1. 𝐂𝐨𝐧𝐭𝐢𝐧𝐮𝐨𝐮𝐬 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 & 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 (𝐂𝐈/𝐂𝐃): Mornings often start with reviewing and enhancing our CI/CD pipelines. Automating builds, tests, and deployments not only accelerates our development cycles but also improves overall software quality

2. 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐚𝐬 𝐂𝐨𝐝𝐞 (𝐈𝐚𝐂): Crafting infrastructure using tools like Terraform or CloudFormation ensures consistency and scalability.

3. 𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐞: Monitoring our systems is crucial. Rapid incident response is key to maintaining high availability and minimizing downtime.

4. 𝐂𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐢𝐨𝐧 & 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐒𝐡𝐚𝐫𝐢𝐧𝐠: DevOps thrives on collaboration. Whether it’s troubleshooting with developers, sharing best practices with teams, or participating in cross-functional meetings, fostering a culture of continuous learning is essential

5. 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐚𝐧𝐝 𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞: Integrating security into every stage of our pipeline is non-negotiable.

6. 𝐂𝐨𝐧𝐭𝐢𝐧𝐮𝐨𝐮𝐬 𝐈𝐦𝐩𝐫𝐨𝐯𝐞𝐦𝐞𝐧𝐭: At the heart of DevOps is continuous improvement. Reflecting on metrics, gathering feedback, and planning optimizations are ongoing processes.

#️⃣JENKINS CI/CD ♾ PIPELINE

1️⃣ User (Developer)
🔣 Role (Code Management and Collaboration): Write, test, and push new code to GitHub. May also be responsible for reviewing pull requests and updating documentation
🔣 How It Works: Developers create new features, fixes, or updates and 'push' this code to GitHub after local testing

2️⃣ GitHub (Code Repository)
🔣 Role (Version Control and Webhooks): Maintains version control and tracks changes in the codebase
🔣 How It Works: Once webhooks are manually set up, GitHub automatically triggers a webhook when the developer pushes new code, sending a notification to Jenkins

3️⃣ Jenkins (Automation Server)
🔣 Role (Continuous Integration and Continuous Delivery): Detects code changes and performs automated tasks like testing and building
🔣 How It Works: Upon receiving the webhook notification from GitHub, Jenkins automatically runs predefined tasks and tests. After successful completion, Jenkins invokes Ansible via a shell command or script

4️⃣ Ansible (Automation and Configuration Management)
🔣 Role (Server Configuration and Deployment): Manages server configurations, can create Docker images, and handles other automation tasks
🔣 How It Works: Following the invocation from Jenkins, Ansible runs predefined scripts to manage server configurations and, if needed, create and prepare a Docker image

5️⃣ Docker (Container Platform)
🔣 Role (Containerization and Orchestration): Creates and manages containers for application deployment, and provides orchestration, networking, and storage features
🔣 How It Works: The Docker image prepared by Ansible is run as a container on the Docker platform

In this way, the process that starts with a developer 'pushing' code to GitHub goes through stages of automated webhook triggering, continuous delivery,

Docker image creation, and container deployment.

All these steps are automated to minimize manual errors and speed up the process.

🐬 Kubernetes Commands: From Beginner to Advanced for DevOps Engineers

🖥 https://dev.to/prodevopsguytech/kubernetes-commands-for-devops-engineers-124o


🎯 Key Concepts
Before we dive into the commands, let's review some fundamental Kubernetes concepts:

➡️Pod: The smallest and simplest Kubernetes object, representing a single instance of a running process in your cluster.
➡️Node: A worker machine in Kubernetes, which can be a virtual or a physical machine.
➡️Namespace: A way to divide cluster resources between multiple users.
➡️Deployment: A higher-level abstraction that manages a replicated application, ensuring that a specified number of replicas are running.
➡️Service: An abstraction that defines a logical set of pods and a policy by which to access them.
➡️ConfigMap and Secret: Mechanisms to inject configuration data into your applications

💡 Kubernetes vs Docker: What's The Difference?

➡️Docker and Kubernetes are the most common names that one might hear in the field of container technology.

➡️Docker is a runtime and containerization platform that was first introduced in 2013 and brought about a microservices-based computing model.

➡️Kubernetes is a platform that manages and runs containers from multiple container runtimes and supports various container runtimes, including Docker.

Linux's file system is tree-like. The base is "/", with everything else branching off.

➡️ Core Directories:

/bin 🛠: Essential binaries, e.g., bash, ls, grep.
/boot 🚀: Boot items like kernel & bootloader.
/dev 🔌: Device files for connected hardware.
/etc 📜: System configuration files.
/home 🏡: User home directories.
/lib 📚: Shared libraries for programs.
/media 💿: Mounts for removable media.
/mnt 🧲: Temporary mounts.
/opt 📦: Optional software.
/proc 📊: System, process, memory info.
/root 👑: Root user's home.
/sbin 🔧: System admin tools, e.g., init.
/srv 🌐: Data for services.
/tmp 🌡: Temporary files.
/usr 🖥: User software.
/var 🔄: Variable data, logs, temp files.

🐧 Linux Commands:

cd 🚶: Navigate.
ls 📋: List contents.
mkdir 📁: Create folder.
rmdir 🗑: Delete folder.
cp 📤: Copy.
mv 🚚: Move.
rm ❌: Delete.

⚠️ Note: Directories like /bin are crucial. Don't modify!
