Hello and welcome to the 5th post 🧵 of System Design, by @mukeshkuiry !
Let's dive into the fascinating world of storage in system design and make this journey more enjoyable with emojis and real-life examples!
🔵 Block Storage: Building the Foundation 🧱
Block storage is like the LEGO of data storage! 🧱 Data is split into small blocks, each with a unique ID. These blocks are stored on physical devices, offering lightning-fast access without fixed paths. Think of it as the building blocks for your data center. 💡
For example, in a cloud infrastructure, think of block storage as the individual bricks that make up the virtual server's storage. Each brick (block) can be easily replaced or expanded without disrupting the whole structure.
📁 File Storage: Organized and Structured 🗂️
File storage is the neat and organized filing cabinet of data storage. It's perfect for structured data and hierarchy lovers. Data is stored in files, files in folders, and folders in directories. Great for when you need a structured approach. 🗃️
For instance, when managing a website, file storage can be compared to the way web content is organized. HTML files in the html folder, images in the img folder, and scripts in the js folder.
📦 Object Storage: Unleash the Power of Flexibility 🚀
Object storage is the superhero of unstructured data! 🦸♀️ It's the go-to technique for data archiving, backups, and massive unstructured data sets. You communicate with your data through a RESTful API, offering immense flexibility. Perfect for handling backups, logs, and more. 💪
Consider object storage as the magical backpack for a traveler. You don't need to know the exact location of each item; you just put them in your backpack (object storage) and retrieve them easily when needed.
🔄 Redundant Disk Array (RAID): Powering Data Resilience 💽
RAID is the fortress of data storage, ensuring your data's safety and speed. It combines multiple disks to create a robust storage device. Externally, it looks like a single disk, but internally, it's a powerhouse with redundancy and performance. 🏰
In a data center, RAID can be likened to a team of security guards working together to protect valuable assets. If one guard (disk) falters, others step in to maintain security without interruption. 🛡️
In the world of system design, these storage techniques are your tools to craft efficient and resilient data handling strategies. Use them wisely and tailor your choices to meet the unique needs of your project.
Happy designing! 🌟 #SystemDesign101
