Abstract

Cloud storage is a storage model where data is stored through a cloud provider that offers storage as a service with data durability, availability and security. All data and configuration is held in the cloud and does not reside on the client site. As technologies evolve, the size and amount of data that applications have to work with is growing exponentially, data retrieval from the cloud impacts the performance of applications. In particular, in the world of High-performance computing (HPC), data needs to be retrieved as quickly as possible in order to perform complex calculations at high speeds. Key-value stores are ideal for HPC environments, since they offer high performance and faster application time. In this thesis we aim to offer the benefits of cloud storage in an HPC environment. We implement two systems, H3 and MongoKreon. H3 is a High speed, High Volume, and High Availability system, with object storage semantics over high performance key-value stores. MongoKreon is an integration layer between MongoDB and a state-of-the-art keyvalue store, Kreon. We describe the design and implementation of each system in detail and present an evaluation analysis, compared to MinIO and Mongo-Rocks.
