Wasmer: Fast, secure, lightweight containers based on WebAssembly
23 days ago
- Introduces WebAssembly-based container technology for secure and fast application execution across multiple platforms.
- Highlights cost-effective scaling with no overpayment for unused capacity, ensuring effortless traffic management.
- Features include seamless local-to-global deployment, millisecond startup times, built-in security via sandboxing, and flexible SDK support.
Performing Live Migrations of VMs
11 days ago
- Sailboxes offer a cost-effective pricing model, charging only for active resource usage per second, making long-horizon agent workflows scalable.
- Live migration technology enables Sailboxes to move VMs between hosts seamlessly, with minimal downtime, supporting ephemeral compute and load balancing.
- A network proxy handles open connections during migrations, spooling packets to maintain connectivity and providing additional features like whitelists and credential injection.
- P2P migrations use userfaultfd for efficient memory transfer, paging in data on demand and using larger memory chunks to reduce latency.
- Elastic memory consumption via virtio-mem allows Sailboxes to dynamically adjust memory usage, optimizing resource allocation and speeding up migrations.
- Sailboxes charge $0.015/vCPU-hour, significantly cheaper than competitors, with billing based solely on active usage for cost-effectiveness.
- Trade-offs include occasional latency spikes during migrations, but these are infrequent and manageable for long-horizon agents.
- Sailboxes are now generally available, with ongoing infrastructure improvements planned for fleet utilization and caching systems.
Aurora DSQL: Scalable, Multi-Region OLTP
8 days ago
- Aurora DSQL is a serverless SQL database for scalable, multi-region OLTP with active-active capabilities.
- It uses a disaggregated architecture separating compute, storage, and transaction coordination into scalable services.
- The system employs multiversion concurrency control with precision timestamps for coordination-free reads and optimistic concurrency control for writes.
- Coordination is minimized, occurring only at commit time via distributed adjudicators and the Journal replication system.
- It supports elastic scaling from zero to millions of TPS while ensuring strong consistency, ACID transactions, and high availability during failures.
