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.

Eladr tokens are designed to incentifised community members as a proof of contribution. Using that they can access diffrent infrastructure built on top of eladr


Using this You can,Buy courses,Reward others and exchange for real money.

6.2 Resiliency

Get exactly what you want. Pay only for what you use.
Our CloudLayer Computing lets you configure a public cloud instance with exactly the number of cores (all 2.0GHz or faster), RAM, and local or SAN storage your application requires. Deployed in real-time, with hourly or monthly billing.
One platform. Endless possibilities.
They seamlessly integrate with Soft Layer dedicated servers and our turnkey Soft Layer Private Clouds. It's all behind one management system (including mobile apps, web portal, and full-featured API) and global network.
Plus, with our proprietary image management system you can capture an image of any server—dedicated or cloud—and then deploy it on any other server—dedicated or cloud. Scale. Migrate. Whichever direction you choose.
Globally distributed. Fully connected.
It's all available out of 13 data centers in the US, Asia, and Europe, integrated by a high-performance private network. Deploy cloud instances in Singapore, dedicated servers in San Jose, and connect them as if they were in one rack—with no back-end network charges or additional connectivity products to buy.
Build your vision on a platform that seamlessly spans physical and virtual devices, public and private clouds, as well as international borders. Build the future.
Provisioning
Cloud provisioning is the allocation of a cloud provider's resources to a customer.
When a cloud provider accepts a request from a customer, it must create the appropriate number of virtual machines (VMs) and allocate resources to support them. The process is conducted in several different ways: advance provisioning, dynamic provisioning and user self-provisioning. In this context, the term provisioning simply means " to provide."
With advance provisioning, the customer contracts with the provider for services and the provider prepares the appropriate resources in advance of start of service. The customer is charged a flat fee or is billed on a monthly basis.
With dynamic provisioning, the provider allocates more resources as they are needed and removes them when they are not. The customer is billed on a pay-per-use basis. When dynamic provisioning is used to create a hybrid cloud, it is sometimes referred to as cloud bursting.
With user self-provisioning (also known as cloud self-service), the customer purchases resources from the cloud provider through a web form, creating a customer account and paying for resources with a credit card. The provider's resources are available for customer use within hours, if not minutes.

High availability and disaster recovery
 Mean time between failures(MTBF).
 Mean Time Recovery(MTTR).
 High Availability(HA).
 Continuous Operations(CO).
 Continuous Availability(CA).
 Availability Management(AM).
The objective of disaster management plan is to provide for the resumption of all critical IT services within as stated period of time following the declaration of disaster.
 Protect and maintain currency of vital records.
 Select a site or vendor that is capable of supporting the requirement of the critical application workload.
 Provide a provision for the restoration of all IT services when possible.

Charging models, Usage Reporting , Billing And Reporting

Consumption-based pricing model
With consumption-based pricing you simply pay for what you use. This is most common for infrastructure as a service (IaaS) offerings such as IBM SmartCloud Enterprise. Under these models you only pay for the amount of resources you actually use such as disk space, CPU time and network traffic.
Subscription-based pricing
In this model you pay to use the service for a period of time – typically on a monthly basis. Your subscription cost typically allows for unlimited usage during the subscription period. So you pay the same amount regardless of the amount or resources you use. This is most common model for software as a service (SaaS) offering such as IBM SmartCloud for Social Business.
Advertising-based pricing
In this model the service is no or low-cost, but features advertising. So the user gets a no charge or heavily-discounted service and the provider receives most or all of their revenue from advertisers. This model is quite common in cloud media services such as free TV provider net2TV.
Market-based pricing
With market-based pricing there is a market price for a service, like per hour of CPU time. The market price varies over time based on supply and demand. As a customer you can buy the service at the current price and use it straight away. Or you can make a bid to use the service at a lower price and if the market price reaches your price then your workload will be activated and you will be charged at your bid price. Amazon EC2 Spot Instances are an example of market based pricing.
The future of cloud pricing models
As cloud computing evolves, so will the pricing models used. The challenge for the industry will be to make these more complicated models easily assessable and understood.
Over time we may see more market-based systems and even pure auction systems. Other possibilities that could eventuate include price comparison sites, aggregation services, group buying, and a futures market for cloud computing services.
As standards such as OpenStack make it easier to move workloads between suppliers, it’s possible that we’ll also see sophisticated deployment engines which query the market, acquire a service at the lowest price, and then deploy workloads to the lowest-price provider.
 Standardised Subscription –based Model
 Pay per use model.
 Premium pricing model.
 Hybrid model.

Basic Requirement

 Fairenes.
 Control.
 Repeatability and Predictability.
 Simplicity

Activity Based

 Derives the cost of an organization outputs(products and srvices).
 Identifies the activities and tasks used in production and delivery of the outputs.
 Identifies the resources consumed in the performances of these processes and instruments these activities so that the cost per task can be rolled up into change per major activity per report.
