Requirements and architectural specification of the base infrastructure

Summary
D1.1 (to be assigned to the subcontractor) will present the outcome of T1.1. It will report on the software and hardware requirements of the base infrastructure and present the architectural specification of the infrastructure and its interaction with the ELG system (including a diagram, with all ELG components). D1.1 will present and justify the selected solutions for (a) creating, managing, configuring a cloud platform (e.g., OpenStack plus anything else required); (b) deploying, scaling, executing containerized applications (e.g., Kubernetes); (c) any other software complementing the selected architecture (e.g., private Docker registries, load balancers etc.); (d) software for monitoring the ELG components, i.e., ELG platform, metadata database, metadata index, LT services execution nodes (e.g., Kubernetes nodes). The justification must include benefits and drawbacks, results from experiments, comparison and contrast with alternatives, etc.
