METHODOLOGY FOR IMPLEMENTING SERVERLESS TECHNOLOGY IN A SYSTEM WITH A MICROSERVICE ARCHITECTURE

Shalgueva Sofiia Leonidovna, Leontieva Tatiana Vladamirovna

Serverless technology is slowly gaining popularity, attracting auto-scaling capabilities, flexible configurations, and most importantly the pay-for-performance model. This paper explores the feasibility of migrating an existing microservices system to a serverless approach using the Knative framework. A methodology is developed to convert conventional microservices running in Kubernetes to serverless mode with support for modes of installing a new network layer or configuring an existing one. A system performance comparison between regular microservices and those converted to serverless mode is given. The results of performance measurements of the new system, including the costs of "cold start" depending on the workload of services and the programming languages in which these services are developed, are presented
