The Birth of SlapOS - 2009
BonjourGrid
What is a Cloud?
| A system which... | Similar to... |
|---|---|
| runs all sorts of services worlwide on a distributed architecture | grid computing |
| manages the order, delivery and billing of online services | ERP or e-commerce |
| suppresses the need for sysadmins through automation | configuration management or devops |
SlapOS Architecture
- ViFiB wants you to host cloud computing at home - IDG, June 15, 2010
- SlapOS: A Multi-Purpose Distributed Cloud Operating System Based on an ERP Billing Model - Smets, Cérin, Courteaud - IEEE, 4-9 July 2011
- Dynamic Resource Allocation in Cloud Environment Under Time-variant Job Requests - Tammaro, Doumith, Al Zahr, Gagnaire, Smets - IEEE, 29 Nov.-1 Dec. 2011
- Practical solutions for resilience - Courteaud, Xu, Cérin - IEEE, Dec. 2012
Everything is a service - 2009
| A service is a running... | Like in... | Pros | Cons |
|---|---|---|---|
| x86 VM image | AWS | Portable, Isolation | Very heavy, Slow IO |
| Linux/BSD chroot tarball | Dotcloud | Fast IO | Heavy, not portable, poor isolation |
| Linux/BSD binary executable | CFEngine | Fast IO, Light | Not portable, poor isolation |
| POSIX recompiled executable | buildout | Fast IO, Light, Portable | Poor isolation |
| POSIX subprocess | buildout | Fast IO, Ultralight, Portable | No isolation |

Success cases: IaaS & CDN
Success cases: PaaS & Hybrid
Success cases: edge
Perspective: improvements since 2009
| A service is a running... | Like in clouds based on... | Pros | Cons |
|---|---|---|---|
| x86 ARM VM image | microVM | Portable, Isolation | |
| Linux containers | Namespaces | Fast IO | |
| Linux portable binary | Snaps | Fast IO, Light, Real-time | |
| POSIX recompiled executable | ZeroVM and successors | Fast IO, Light, Portable, Real-time | |
| POSIX subprocess | Secure languages | Fast IO, Ultralight, Portable, Real-time |
Perspective: new service classes
| A service is a running... | Like in... | Pros | Questions |
|---|---|---|---|
| HTML5 worker | Chrome | Portable, Isolation, Light, Cloudless | Memory? Security? IO? |
| WASI executable | Wasmtime | Portable, Isolation, Light | Memory? Security? IO? ecosystem? |
| IoT firmware | LiteOS, NuttX, RIOT | Lower CO2 impact | Memory? Security? ecosystem? |
| Non-POSIX subprocess | cdnbye | Portable, Isolation, Light, Cloudless | Memory? Security? IO? |
Solomon Hykes, a co-founder of Docker, wrote in 2019, "If WASM+WASI existed in 2008, we wouldn't have needed to create Docker"
Do we still need edge?
| Goal | Continental DC | Regional DC | Local DC | On-premise | Browser / IoT / UE |
|---|---|---|---|---|---|
| Distance (ms) | < 50 | < 2 | < 0.5 | < 0.1 | 0 |
| Minimize cost | ✅ | ✅ | |||
| Minimize application latency | ✅ | ||||
| Minimize energy | ✅ | ❓ | ❓ | ✅ | |
| Survive Internet shortage | ✅ | ✅ | |||
| Sub ms control loop | ✅ | ✅ | |||
| Maximize transactions | ✅ | ❓ | ❓ | ❓ | |
| CDN | ✅ | ❓ | ❓ | ✅ | |
