  1. 1.  How does cloud computing and blockchain impact your life? Topics:
  2. 2. Cloud Computing
  3. 3. Definition: Cloud computing is a technology that uses the internet for storing and managing data on remote servers, and then access data via the internet.
  4. 4. Description of Cloud Computing: This type of system allows users to work on the remote. Cloud computing customers do not own the physical infrastructure; they rent the usage from a third-party provider. Cloud Computing and the Essential characteristics of cloud services are On-demand self- service, Broad network access, Resource pooling, rapid elasticity. Cloud computing is so successful because of its simplicity in its usage. They are a cost-effective solution for enterprises. One such example is Google cloud – It is a suite of public cloud services offered by Google. All the application development run on Google hardware. They include Google Compute Engine, App engine, google cloud storage, Google container engine.
  5. 5. There are three types to depend on services: 1) SAAS (Software-as-a-Service)- Examples Microsoft Office Live, Dropbox. 2) PAAS (Platform-as-a-Service)- Examples Google App Engine 3) IAAS (Infrastructure-as-a-Service) – Examples IBM cloudburst. Generally ,There are three types of cloud computing: Private Cloud: It functions for single organizations on a private network and it is secure. Ex: Corporate IT department. Public Cloud: It is owned by the cloud service provider. Ex: Gmail. Hybrid cloud: It is the combination of both private and public versions of the cloud. Ex: Proprietary technology.
  6. 6. How Does Cloud Computing Work? The cloud is basically a decentralized place to share information through satellite networks. Every cloud application has a host, and the hosting company is responsible for maintaining the massive data centers that provide the security, storage capacity and computing power needed to maintain all of the information users send to the cloud.
  7. 7. How Does Cloud Computing Work? The most prominent companies hosting the cloud are major players like Amazon , Microsoft, Apple and Google, but there's also a plethora of other players, large and small. These hosting companies can sell the rights to use their clouds and store data on their networks, while also offering the end user an ecosystem that can communicate between devices and programs
  8. 8. Advantages And Disadvantages of Cloud Computing : As we have studied in the above section about the examples of cloud computing so now we are going ahead with the advantages and disadvantages of cloud computing Advantages :  Reduced cost: The billing model is paid as per usage. Initial expensive and recurring expenses are much lower than traditional.  Increased Storage: They have massive storage and maintenance of large volumes of data.  Flexibility  They are scalable, as we can pay for the amount of storage required. And are used in emergency back up plan.
  9. 9. Disadvantages:  Performance on shared infrastructure can be inconsistent. Servers maintained by cloud computing can fall to natural disasters and internal bugs.  Privacy and security in the cloud are much more concerns.  reliability, As well as privacy. Vendor lock and failure is also another concern in cloud computing.  Data Transfer costs: Outbound data transfer over the monthly basis is charged as per GB Basis.  Downtime: If the internet connection is down, Unable to access any of the applications, server or data from the cloud.
  10. 10. Impact Our life: 1. Social Impact 3. Development 2. Education 4. Health
  11. 11. Block-Chain
  12. 12. Definition:Blockchain is a database system that maintains and records data in a way that allows multiple organizations and individuals to confidently share access to the same data in real-time, while mitigating concerns around security,privacy and control.
  13. 13. There are four types of Blockchain: 1. public blockchains 2. private blockchains 3. consortium blockchains 4. hybrid blockchains.
  14. 14. 1. Secure – Since it is an open source ledger, every transaction is made public. This leaves no room for fraud. The integrity of the blockchain is monitored by minors who have their eyes on all the transactions. 2. No third party interference – No government or financial institution has control of the cryptocurrencies based on blockchain technology. This means no government can meddle with the value of the currency. 3. Secure transactions – The blockchain responsible for keeping record of all the transactions cannot be edited or manipulated. Both ends of a transaction and the public can view the transaction data at any given time. This makes online transactions more secure. 4. Instant transactions – Blockchain technology transactions are completed in a few minutes. Take for example a bank transaction made to a person with a different bank account. It takes two days minimum to complete the transactions. At this time, the person doing virtual transactions with crypto can complete a series of transactions. Advantages:
  15. 15. Disadvantages: Difficulties with Updating and Elimination of Errors: 1. The application must be updated on each node of the P2P network or forked if any part of the nodes don’t accept the amendments. Network Robustness for Dedicated Purposes: 1. All applications have a business logic behind them. The logic defines how new applications must work in terms of business requirements. By nature, blockchain employs a strict logic that doesn’t allow redesign without the loss of benefits leading to the need for logical business changes to be acceptable to the blockchain solution. Difficulty of Development: 1. Applying very complex protocols to achieve consensus and allow for scaling from the beginning is very important. One cannot hastily implement an idea hoping to later add new features and expand the application without redeployment of the network or forking. 2. Applications don’t normally require third-party APIs to store and retrieve data. The decentralized app shouldn’t also depend on other Dapps. This might sound good in theory but causes difficulties in practice.
  16. 16. Using the Bitcoin system as an example, here’s how blockchain — also known as distributed ledger technology — works: The purchase and sale of bitcoin is entered and transmitted to a network of powerful computers, known as nodes. This network of thousands of nodes around the world vie to confirm the transaction using computer algorithms. This is known as bitcoin mining. The miner who first successfully completes a new block is rewarded with bitcoin for their work. These rewards are paid for by network fees, which are passed on to the buyer and seller. The fees can rise or fall depending on the volume of transactions. How does blockchain work?
  17. 17. After the purchase is cryptographically confirmed, the sale is added to a block on the distributed ledger. The majority of the network must then confirm the sale, in a process known as “proof of work.” The block is permanently chained to all previous blocks of bitcoin transactions, using a cryptographic fingerprint known as a hash, and the sale is complete. How does blockchain work?
  18. 18. How Blockchain Technology can Impact our Daily Lives? Here are some of the significant applications of blockchain technology that could transform our day-to-day lives in the near future: 1 .Digital Identity Blockchain technology can enable everyone to acquire a unique and secure digital identity for all purposes, without having to reiterate it every now and then. Digital security in areas such as VoIP through the cloud are a massive problem at present; the lapses in cybersecurity are likely to cost the industry about $6 trillion annually by the year 2021. Digital identity is intricately woven into all aspects of culture, commerce and other human activities worldwide; such as banking, healthcare, online retailing, national security, citizenship documentation etc.
  19. 19. 2. Digital Voting Security is currently the greatest barrier to conduct the electoral processes online. But, by using the blockchain technology a voter can check that the person’s vote has been successfully transmitted while maintaining complete anonymity. Blockchain was effectively used for the first time in Denmark in 2014 by the political organization, Liberal Alliance. Generally, the voter turnouts are still very low even in many advanced democracies. Blockchain-powered distributed digital voting can enfranchise many of those who are currently not into active voting processes. 3. Decentralized Notary Services Timestamp is one of the special features of blockchain-based transactions. Here each transaction is a time-wrapped piece of data (called a hash) validated by the entire network of blockchain system at a particular time. This essentially confirms the existence of the time- stamped piece of data, and makes it provable in a court of law. Until now, the proof of such transactions could be provided only by centralized notary services.
  20. 20. 4. Smart Contracts The blockchain technology makes the world of smart contracts a reality. These are blockchain based digitized contracts with programmable features, and are legally binding. Here the cryprocurrency network acts as the ‘3rd party executor’, instead of any trusted central authority, for the release of agreed funds upon meeting certain pre-determined conditions. Smart contracts will have far-reaching implications in matters concerning real estate, wills, property bequeathals etc. This will make the businesses more efficient, and the legal system more speedy and equitable.
  21. 21. 5. International Funds Transfers Blockchain-based bitcoins could provide standard way of international transactions much faster and at much lower costs than they are done today through conventional banking channels. Bitcoins are perfectly designed to serve as the standard means of international payments or remittances. Currencies can be exchanged across the globe almost instantaneously and at a small fraction of the current cost, without any centralized or government control.
  22. 22. 6. Healthcare Blockchain can be used to create universal records with a timestamp. These universal records virtually form a library of diverse databases from which rhe required data can be retrieved. ‘Patientory’ is one such vast library of data pertaining to patients and healthcare. It can be extremely useful for administering precision medicare. The proliferation of wearable devices, sensors and health applications add a constant flood of data to ‘Patientory’. Current healthcare systems are not well-designed to cope up with the explosion of the various and voluminous medical data being generated today.
