Upload Large Files to Azure Blob 5x Faster — The Overlooked Secret You Need

Uploading a 10GB file to Azure Blob Storage shouldn’t feel like waiting for Windows 98 to boot up. 🕰️💾

If you’ve ever tried uploading a massive file to Azure Blob and watched it crawl slower than a snail 🐌 (or worse — crash halfway 😭), this guide is your superhero cape. 🦸‍♂️🦸‍♀️

Today, I’ll show you the overlooked secret to 5x faster uploads using chunking and parallelism — your new best friends for handling large file uploads to Azure Blob Storage with C# .NET Core 8.

🎯 Why Chunking & Parallelism?

Uploading large files in one go is like trying to eat an entire pizza in one bite. 🍕💀

• Chunking breaks that pizza (or file) into smaller, delicious slices.
• Parallelism means eating multiple slices at once (if you’re that kind of person 🍕🍕🍕) — in tech terms, this means faster uploads.

🛑 Without Chunking:

• Slow uploads. 🐢
• Failures mean starting over. 😡
• High memory usage. 💥

✅ With Chunking + Parallelism:

• 5x faster uploads thanks to simultaneous transfers. ⚡
