We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

 SOA is very useful architectural style for implementing applications in the cloud.
 SOA would provide the best way to leverage and consume application service provided by the cloud.
 Developing integrated service management approach for both the application services and infrastructure services together will drive efficiency in IT operations by improving the resource utilization and improving the service levels.
 It enable business agility by aligning IT with the business.


 Deliver and leverage cloud based services.
 Use web services-service requestors, service registry, service providers.
 It helps to interoperability and extensibility and shared infrastructure.
 Self service capabilities and virtualized.
 Cloud computing is an infrastructure management and services deployment method.
 Cloud share characteristic of SOA with flexibility and agility.
 Service-oriented architecture is an application framework for building better application.
 SOA design pattern is composed of loosely coupled, discoverable, reusable.
 Interoperable platform-neutral services


 SOA is defined by what a service is. Service are defined by the following characteristics.
 Explicit, implementation-independent interfaces.
 Loosely bound.
 Invoked through communication protocols.
 Stress location transparency and interoperability.
 Encapsulate reusable business function.
 SOA treats elements of business like:
 Business processes.
 Underlying IT infrastructure.
 Secure standardized components.
 Changing business priorities.
 When we look at the SOA vision we need to look at 3 aspects:
 The business view of service.
 The architecture view of service.
 The implementation view of service.
 SOA Lifecycle.
 Combining new and existing services.
 Secure and integrated environment for people, processes and information.
 Customer manage both IT and a business Perspective.
 Provide guidance and oversight for the SOA project.
 Service-Oriented Computing.
 Comprise a specific set of design principles.
 It use "separation of concerns" design philosophy.
 IT virtualized the architectural aspects of the service orientation to make process simple
 It helps to achieve business goals


 Major industry analyst view cloud infrastructure as a key IT ingredients for business agility. Analyst recommend an IT infrastructure that is:
 Shared across customers, business units and application.
 Dynamically driven by business policies and service level requirements.
 The analyst view IT visualization and IT Automation as 2 major elements in realizing infrastructure as service.


 Cloud infrastructure has many components, However, they need not all be implemented concurrently.
 Service can be divided into four domains.
 Application Services.
 Information Services.
 Common IT Services.
 Infrastructure Services.
SOA offers number of business values.
 Business Agility.
 This helps in defining the right time to launch or rapidly scale the deployment efforts needed to implement the new solutions.
 Lower Cost of Operations.
 This helps in utilizing the virtual pools efficiently which decreases the chance of procuring the new systems.
 It helps in increasing in overall effectiveness when we work in an automated environment.
 Improved service levels.
 SOA-based infrastructure helps to adhere to the SLAs efficiently and helps in orchestrating the resource as per the rules and policies.
 Business analytics helps to decide different predictive, proactive, alterative approaches when we follow SOA.
 Efficient Information Management.
 Information dissemination.
 Data replication.
 Business continuity protection.
 Regulatory compliance.
 Maximizing resource utilization.
 Rapid deployment of new application.
 More timely response to changing business conditions.
 Regulatory Compliance.
 We need monitoring to track the performance of the services to confirm that they comply with the regulatory compliances.
 It is important to adhere with energy emission regulations and efficiencies to adopt Greener solutions
 If we have centralized data storage it will help the audit process. Centralized data storage facilitates and accelerate audits.
 Energy Efficiency.
 Computing
 Storage
 Network utilization
 Datacenter energy efficiency

8.6 Cloud IT Service Management


 Organization intent upon leveraging cloud infrastructure should consider the following steps:

 Analysis and Strategy.

 Planning.

 Implementation.

 Value-Driven.

 SOA and Cloud infrastructure.

 SOA based cloud computing model builds on the IT and internet models.

 SOA based cloud computing enabling new ways of doing business.

 SOA to consider the business underlying principle and it helps to determine the cost of investment.

 SOA Business and IT Services.

 It helps to measure performance of business functions and manage the runtime application.

 Generate the metrics to measure the performance is pivotal in the progress of the business.
