Service (SaaS) application. A combination of multi-tenant application architecture, Cloud Computing, auto-scaling and load-balancing features provide the required support for the solution to be more scalable with sudden workload. Furthermore, the system APIs can run on a separate container making it highly scalable. Both the middle tier and the Blockchain.

Resource utilisation, scaling up resources when needed then scaling down resources when they are not being used. Additional native cloud services (e.g. Auto Scaling, multiple storage services, and relational database as service) can help ensure that resources are being used efficiently, and cost optimisation is achieved through a continuous cycle of assessment, benchmarking, and integrationWe use Amazon VPC to control network access and increase privacy. Data in transit is encrypted using TLS across all services. Daily automated snapshots ensure business continuity under the unlikely event of system failures. A high degree of data security is achieved in the platform using a combination of Blockchain, Encryption, SSL Secure Communication, authentication, and role-based user authorization. While SSL protects the data in transit, across the system role-based access control ensures that only users with relevant access can perform actions. All the API calls as well are secured through an access token and SSL layers. Comprehensive logging both at the middle tier and Blockchain ensures a detailed audittrail of operations and to debug problems in configuration and code.
