SLOG: serializable, low-latency, geo-replicated transactions Ren et al., Strict serializability reduces application code complexity and bugs, since it behaves like a system that is running on a single machine processing transactions sequentially. That’s where SLOG (Serializable LOw-latency, Geo-replicated transactions) comes in.

Microservices-based architectures and software containers enable organizations to deploy and modify applications with unprecedented speed. At the lowest level, SLIs provide a view of service availability, latency, performance, and capacity across systems. However, cloud complexity has made software delivery challenging.

Within this paradigm, it is possible to run entire architectures without touching a traditional virtual server, either locally or in the cloud. In a serverless architecture, applications are distributed to meet demand and scale requirements efficiently. When an application is triggered, it can cause latency as the application starts.
