User-Defined Cloud

https://cseweb.ucsd.edu/~yiying/UDC-HotOS21.pdf

• Cloud computing evolves --> services, instance types

• Life cycle

  • Provider identifies a new type of application / hardware

  • Provider develops / adapts SW/HW infrastructure

  • Provider launches a new service or extends an existing one

• E.x. health industry

  • Secure storage and processing

  • But today:

    • No on-demand accelerator: pay extra with VMs

    • No secure accelerator: use secure CPU and run slower

    • No fine-grained tuning of systems feature: build your own

      • Combine a set of services

• No right service for niche applications

  • Users have to build a local cluster or use a third-party services

• Cloud providers "define" the cloud to accommodate the user needs they deem popular

• Users know what is needed to run their workloads and should be allowed to get what they need

• Idea:

  • user-define computing resources and features for their own workload

  • cloud provider supply software and hardware infrastructures under the hood

User-define cloud

What users can define

• Fine-grained hardware and software building blocks put together on demand like Lego pieces

• Find the right combination of HW / SW

Benefits:

• Users

  • Customize public cloud for exactly what they need

  • No need to wait for providers to prepare new features

    • Fast time to market, better performance

  • No need to manage SW/HW infra

  • Pay as we go

    • Low cost

• Providers

  • Build one set of configurable SW/HW infra

    • Cheaper to develop and maintain

  • Attract niche users

  • Charge a higher unit resource price

    • More profit
