Summary

• Innovations by AWS in Hardware for Serverless computing

Highlights

• AWS Serverless offerings (to name a few): Lambda, S3, DynamoDB, Fargate
• Amazon Aurora
  • Fully compatible PostgerSQL & MySQL DBs
  • Biggest innovation of Aurora is internal optimized storage system: powered by Grover
    • Aurora sends the log (core of any DB) to Grover, which then writes to multiple AZs!
  • Amazon Aurora Serverless launched in 2018
  • Databases on Nitro hypervisor: however when DB needs more memory, Nitro won’t be able to give that, since it would mean to bring down that DB instance & configure a new one with more memory, which is as good as DB failover. Nitro allocates static resources to an instance
    • To avoid this, AWS came up with Caspian: Combination of new hypervisor + heat mgmt planning system + few changes to DB engine
      • Caspian allows Aurora Serverless to resize in milli-seconds!
      • Caspian uses an approach called Co-operative oversubscription
      • Caspian can dynamically allocate resources, unlike Nitro
      • 
      • 
  • New Aurora Limitless Database
    • DB Sharding in Serverless world
    • Managed horizontal scale-out beyond the limits of a single instance
    • Innovation 1: New Request Routing Layer
    • Innovation 2: Fully Elastic Shards
    • Innovation 3: Reducing Clock error bounds via Amazon Time Sync Service
• New Amazon ElastiCache Serverless
• Amazon Redshift Serverless (launched in 2021)
  • Scales depending on Query Volume
  • New Next gen AI driven Scaling & Optimization: to address the challenge by one off massive Query which slow downs rest of the queries
• Quantum Computing:
  • AWS Centre for Quantum Computing established at Caltech in 2019
  • Quantum computing chip launched (in prototype)
