 Amazon S3 Storage Classes: Choosing the Right Tier for Your Data

Amazon S3 (Simple Storage Service) is a cornerstone of cloud storage, offering unmatched durability, scalability, and flexibility. But with multiple storage classes available, choosing the right one can be tricky. Whether you're storing frequently accessed files or archiving data for compliance, understanding S3’s storage tiers is key to optimizing performance and cost.

Let’s break down each class and explore when to use them.

S3 Standard — For Frequently Accessed Data

Use Case: Ideal for active workloads like websites, mobile apps, and real-time analytics.

  • Minimum storage duration: 30 days

Best For:

  • Long-term backups

  • Archived logs

  • Disaster recovery files

S3 One Zone-IA — Cost-Effective for Non-Critical Data

Use Case: Stores data in a single Availability Zone, making it cheaper but less resilient.

Key Benefits:

  • 20% lower cost than Standard-IA

  • Suitable for easily re-creatable data

  • Availability: 99.5%

Best For:

  • Secondary backups

  • Reproducible datasets

  • Non-critical logs

S3 Intelligent-Tiering — Smart Storage for Unknown Access Patterns

  • No performance impact

  • Ideal for unpredictable workloads

Best For:

  • Data lakes

  • Machine learning datasets

  • Media archives with variable access

S3 Glacier Instant Retrieval — Fast Access to Archived Data

Use Case: For long-term data that’s rarely accessed but needs millisecond retrieval.

Key Benefits:

  • Lower cost than Standard-IA

  • Retrieval in milliseconds

  • Minimum object size: 128 KB

Best For:

  • Medical records

  • Image hosting

  • Compliance archives

S3 Glacier Flexible Retrieval — Balanced Archival Storage

Use Case: For data accessed once or twice a year with flexible retrieval times.

Key Benefits:

  • Retrieval options: expedited, standard, bulk

  • Free bulk retrievals

  • Minimum storage duration: 90 days

Best For:

  • Disaster recovery

  • Historical records

  • Regulatory archives

S3 Glacier Deep Archive — Lowest-Cost Long-Term Storage

Use Case: For data that’s rarely accessed but must be retained for years.

Key Benefits:

  • Cheapest S3 storage class

  • Retrieval time: 12–48 hours

  • Minimum storage duration: 180 days

Best For:

  • Compliance data

  • Legal documents

  • Tape archive replacement

Tinder — Scaling for Millions of Swipes

Challenge: Tinder faced massive traffic and needed to scale quickly while maintaining stability.

Solution: Migrated 200+ services to Kubernetes, running a cluster with 1,000 nodes and 48,000 containers.

Solution: Shifted customer-facing applications to Kubernetes.

Impact:

  • Reduced deployment time from 45 minutes to just a few

  • Enabled developers to push updates independently

  • Increased agility across teams

 3. Airbnb — Empowering 1,000+ Engineers

Challenge: Needed scalable continuous delivery for hundreds of microservices.

Solution: Adopted Kubernetes to support 250+ services and 500+ daily deploys.

Impact:

  • Streamlined CI/CD pipelines

  • Improved developer autonomy

  • Enhanced infrastructure scalability

 4. Pinterest — Managing Billions of Recommendations

Challenge: Scaling infrastructure to support 250M+ users and 10B+ daily recommendations.

Solution: Migrated from EC2 to Docker, then to Kubernetes for orchestration.

Impact:

  • Reduced resource consumption by 30%

  • Restored 80% of capacity

  • Enabled faster idea-to-production cycles

 5. Pokémon GO (Niantic) — Planet-Scale Gaming

Challenge: Unexpected surge in users caused server crashes and scaling issues.

Solution: Deployed game logic on Google Kubernetes Engine (GKE).

Impact:

  • Supported 500M+ downloads and 20M+ daily users

  • Enabled real-time updates and scaling

  • Freed engineers to focus on game features

 6. Goldman Sachs — Modernizing Financial Infrastructure

Challenge: Migrating 5,000+ applications with 90% of compute power.

Solution: Adopted Kubernetes for large-scale orchestration.

Impact:

  • Accelerated migration timelines

  • Improved resource allocation

  • Strengthened tech-driven reputation

FUNCTIONS

 FUNCTIONS Functions are like reusing code that you have written rather writing everything from scratch. For example like  in CPP //header file #include<iostream> using namespace std; // main program int main(){ //this will display hello world cout<<"hello world"; return 0; } now with function #include<iostream> using namespace std; //funtion declaration void Hello_World(){} int main(){ //calling funtion Hellow_World(); return 0; } //defining funtion void Hello_World(){ cout<<"hello world"; } here funtion can be divided in 3 parts Declaration:  means to tell it's name and it's arguments and with their type. Defination:means to tell what will be inside of it and what will it do. Calling: means to call that function using it's name or provoking it. So by this we are calling the function to print hello world rather writing the code from scratch. For more you can watch below link of YoutTube video :  Functions

Why companies prefer Linux ?

Why Companies Use Linux: 1. Open Source Freedom Companies can access and modify the source code without licensing restrictions. No vendor lock-in, meaning more control over systems and infrastructure. 2. Security and Stability Linux is less vulnerable to malware and cyberattacks. It can run for years without crashing—ideal for servers and networks. 3. Cost-Efficiency Most Linux distributions are free. Saves thousands in licensing costs compared to Windows or macOS. 4. Scalability and Performance Works efficiently across systems: from embedded devices to massive cloud data centers. Can be fine-tuned for speed and performance. 5. Development-Friendly Rich support for programming languages, tools (Git, Docker, Kubernetes), and automation. Perfect for building and deploying software quickly and reliably. 6. Cloud & Server Dominance Nearly all cloud providers (AWS, Azure, Google Cloud) run Linux-based servers. Powers most web hosting services and critical infrastructure worldwide.  ...

Why companies use Docker?

   Why Companies Use Docker 1. Consistent Environments Docker containers ensure that applications run the same across development, testing, and production. Eliminates the “it works on my machine” problem. 2. Rapid Deployment & Scalability Containers launch in seconds, enabling fast rollouts and updates. Ideal for microservices and cloud-native architectures. 3. Cost Efficiency Multiple containers can run on a single host, reducing infrastructure costs. Lightweight compared to virtual machines. 4. Portability Docker containers can run on any system with Docker installed—cloud, local, or hybrid environments. 5. Security & Isolation Each container is isolated, minimizing the risk of system-wide vulnerabilities. Easier to apply updates and patches without affecting other services.  Real-World Use Cases by Companies Company Use Case & Benefits 1.Netflix Uses Docker to deploy thousands of containers daily via its internal platform Titus. Enables massive scalability ...
