Blockchain Technology is one of the computing technologies touted to likely bring about disruption in ways people conduct their transactions. By design, blockchains are decentralized, peer to peer, distributed consensus, and have anonymity property thus eliminating the need for a central Authority. Blockchain has been widely used in crypto currencies, with other uses lip frogging at slower paces. This paper explores the various uses cases that have been advanced for blockchain highlighting the shortcomings of the listed cases. The paper expounds more on usage of blockchain in electoral processes, analyzing existing voting use cases and identifying the shortcomings of the listed blockchain voting use cases. A more elaborate voting use case is conceptualized with clear description on how to generate Digital Votes, linked to a NONCE and previous Digital Votes. The process of vote validation is explained with the main component of the blockchain voting being highlighted as the Smart Contract.
Cloud service providers have a QoS monitoring capability integrated in their cloud platforms. This is to aid in monitoring the performance of the platform as well as for Service Level Agreement confirmation to the clients. Unfortunately this arrangement serves the interest of the cloud provider more than the cloud client since the service providers gauge their services using their own tools. This paper performs a comparative study on the capabilities of the client based vendor neutral QoS tool, developed from a vendor neutral QoS monitoring model against the cloud provider integrated QoS monitoring tools. The comparison was done on four global SaaS cloud service providers, namely SalesForce, Google, Hubspot and Shopify. From the comparative study, it emerged that the client based vendor neutral tool has more capabilities than the cloud provider integrated tools since it has the capability to monitor three key QoS metrics, namely service response time, service availability and service stability as opposed to the cloud providers’ tools which only have one quantitative capability. Further the vendor neutral model can be used across any cloud platform that is accessible via the web browser. This provides a capability for cross platform performance comparison for the various cloud providers. This can aid in decision making with regards to which cloud service provider to procure based on the desired performance.
