Evolution of Cloud Computing

  • The concept of cloud computing is to rent computer resources. This concept was initially proposed in the 1950's. 
  • Five innovations were crucial in transforming cloud computing into what it is today. 
  • Distributed systems and its peripherals, virtualization, web 2.0, service orientation, and utility computing are all examples of this.

Evolution of Cloud Computing

Distributed Systems and its peripherals
  • A distributed system is made up of numerous separate systems that seem to users as a single entity. 
  • The goal of distributed systems is to share resources while still making effective and efficient use of them. 
  • Scalability, concurrency, continuous availability, heterogeneity, and failure independence are all properties of distributed systems. 
  • The fundamental issue with this system was that all of the systems had to be present at the same time and in the same place. 
  • As a result of distributed computing's solution to this challenge, three new forms of computing emerged: mainframe computing, cluster computing, and grid computing.
Cluster computing:-
  • Cluster computing began in early 1980 as a better solution to the mainframe computer. 
  • Each machine in the cluster was connected to the others via a high-bandwidth network. 
  • These were far less expensive than mainframe systems. These were also capable of doing complex calculations. 
  • As a result, the cost issue was resolved to some extent, but the issue of geographical constraints remained. 
  • Grid computing was presented as a solution to this problem.
Grid computing:-
  • Grid computing was first presented in the 1990s. 
  • Grid computing is described as a group of computers working to complete a task that would be impossible for a single machine to complete. 
  • To act as a virtual supercomputer, all machines on that network use the same protocol.
  • Although it solved some problems, as the distance between the nodes increased, new problems emerged. 
  • The main issue that was experienced was a lack of high-bandwidth connectivity, as well as other network-related problems. 
  • As a result, cloud computing is frequently referred to as "grid computing's successor."
Virtualization:-
  • It was first presented around 40 years ago. 
  • It's the technique of establishing a virtual layer on top of hardware that allows the user to run several tasks on the same device at the same time. 
  • It's a vital component of cloud computing. One of the most prevalent types of virtualization is hardware virtualization.
Web 2.0:-
  • It's the mechanism by which cloud computing services communicate with their users. We now have interactive and dynamic websites thanks to Web 2.0. 
  • It also adds to the flexibility of web pages. Google Maps, Facebook, Twitter, and another web 2.0 applications are popular examples. 
  • Without a doubt, social media is only available because of this technology. In 2004, it became extremely popular.
Service orientation:-
  • It serves as a cloud computing reference model. It supports applications that are low-cost, flexible, and upgradeable. 
  • In this computer model, two significant principles were introduced. 
  • Quality of Service (QoS), which includes the SLA (Service Level Agreement), and Software as a Service were the topics (SaaS).
Utility computing:-
  • It is a cloud platform that specifies high availability strategies for pay-per-use services such as computation, as well as other significant services such as storage, infrastructure, and so on.

Advantages of Cloud Computing

 Advantages of Cloud Computing 

Cloud Computing Benefits

  1. Cost Saving
  2. Flexibility
  3. 24/7 Availability
  4. Reliability
  5. Scalability
  6. High Performance
  7. Security
  8. Unlimited Storage
  9. Easy Backup and Restore
  10. Highly Accessible
  11. Automatic Software Update

Cost Saving

  • People want to shift to the cloud for a variety of reasons, the most important of which is cost savings.
  • If your firm decides to build a data center, it will need to spend in both hardware and software. The infrastructure must then be managed by qualified personnel.
  • Even once the data center is put up, it must be maintained 24 hours a day, seven days a week for proper operation. It can quickly add up to a cost that many small businesses cannot afford.

Flexibility

  • When it comes to provisioning resources like memory and compute capacity, cloud computing is extremely flexible.
  • You can start small and gradually expand your infrastructure as your company grows.
  • No matter how big our company gets, cloud computing keeps us safe.
  • We shall always be ready to take on the weight.

24/7 Availability

  • Your application should be available 24 hours a day, seven days a week. Highly available systems should be able to satisfy requests even if there is a failure or a natural disaster.
  • When it comes to availability, the majority of cloud service providers are trusted. Many of them, in fact, guarantee 99.99 percent up-time.

Reliability

  • Disaster recovery is now easier than ever thanks to cloud computing. Multiple copies of our data are kept in various locations/availability zones in the cloud.
  • So, even if one of them crashes or the location is hit by a natural calamity. The data is secure since it can be restored from a different place.

Scalability

  • Scalability refers to the ability to scale up or down storage, CPU, and other resources as needed.
  • Infinite scalability is one of the benefits of cloud computing. You can scale as much or as little as your system requires, whether it's storage, computation, or something else.
  • That means it not only scales, but it is also more efficient because the capacity may be reduced when not in use. You can't do that with a data center on your property.

High Performance

  • A network of data centers underpins cloud computing services. The technology and software in the data centers is extremely powerful. 
  • They're also constantly upgraded to the most up-to-date, quick, and efficient hardware, ensuring high performance.

Security

  • Many cloud providers now offer a set of policies and advanced strategies to help us improve our overall security. As a result, we are better able to defend ourselves against a wide spectrum of cyber-attacks.
  • Security in the cloud, however, is a shared duty. This means that cloud service providers are responsible for cloud (infrastructure) security, while clients are liable for cloud security (For their application)
  • Service providers, on the other hand, present us with methods for securing our application.

Unlimited Storage

  • Data is growing at a breakneck speed these days. Companies have data in the terabytes or exabytes. They seek a low-cost, flexible storage solution that can grow with their needs.
  • One of the benefits of cloud computing is the ability to store as much data as needed. You don't have to be concerned about disc space.

Easy Backup and Restore

  • Gone are the days when we would save our photos on a laptop, hard drive, or other storage device. Our phones are now linked with the cloud (for example, Google Images) to store photos, contacts, and other information.
  • Even if you change phones, simply set your email and your mail, contacts, and images should all be restored. Isn't it simpler to copy the data to a hard disc and then restore it?

Highly Accessible

  • Consider whether you have your photo on your laptop or phone. You can only use that laptop or phone to access it. If, on the other hand, your images are kept on Google Photos, you can access them from any computer system in the globe.
  • On other words, keeping data in the cloud makes it simple to access that data from anywhere in the globe on any computer.
  • Simply said, If I say cloud computing, I mean that it allows us to have our data at our fingertips.

Automatic Software Update

  • Nothing is more inconvenient than having to apply software updates when you have more pressing matters to attend to.
  • When you use the cloud, you or your office's IT staff are no longer responsible for software upgrades at regular intervals.
  • Cloud-based software provides a variety of advantages to businesses of all sizes, including the flexibility to access software from any device via a native app or a browser.
  • As a result, users may seamlessly transfer their files and preferences from one device to another.
  • Cloud computing entails a lot more than just being able to view information from numerous devices.
  • Users may check their email on any computer thanks to cloud computing services, and they can even store files using Dropbox and Google Drive.
  • 6 & 7 Users can also use cloud computing services to back up their music, files, and images, ensuring that they are available promptly in the event of a hard drive accident.
  • It also provides a wealth of cost-cutting opportunities for large corporations. Before the cloud became a viable option, companies had to purchase, create, and maintain costly information management systems and infrastructure.
  • Companies can replace expensive server centres and IT personnel with fast Internet connections, allowing people to finish work by interacting with the cloud online.

Cloud Storage

 What is cloud storage?

  • In this fast-moving world it become necessary to store data on the cloud storage. The biggest advantage of cloud storage is that we can store any type of data in digital form on the cloud. 
  • Another advantage of cloud storage is that we can access data from anywhere, anytime on any device. There are many cloud storage providers such as, Google Drive, Dropbox, OneDrive, iCloud, etc. 
  • They provide free service for limited storage but if you want to store beyond the limit, you have to pay. In this section, we will discuss what is cloud storage, uses of cloud storage, and its architecture in detail.

Cloud Storage

  • The cloud storage is a computer data storage model in which the data that is digital in format is stored, and hence it is said to be on the cloud, in logical pools. 
  • This physical storage consists of multiple servers which can be located in the different parts of the country or may be in different parts of the world depends on many factors. The maintenance of these servers is owned by some private companies.
  • The cloud storage services are also responsible for keeping the data available and accessible 24x7, and it also safeguard the data and run the physical environment. 
  • In order to store user, entity, or application information, individuals and organisations purchase or lease storage capacity from providers.
  • The Cloud storage resources, for example a cloud desktop storage, a cloud storage portal or a Network-based content management system in the cloud. 
  • These all can be easily accessed with the help of a co-located cloud computing service or it can be a web service application programming interface which in general is known by the name of API or applications that use the API.


Architecture of Cloud Storage

Cloud Storage


  • In terms of interfaces the cloud storage is basically based on highly virtualized technology which is more like broader cloud computing. 
  • It is possible to use cloud storage services from an off-site provider (Amazon S3) or from an on-site provider (ViON Capacity Services).
  • Usually, cloud storage refers to a hosted object storage service, although the concept has extended to include other forms of data storage, such as block storage, that are also available as a service.
  • Some of the examples of cloud storage which can easily be hosted and deployed with cloud storage characteristics are as follows -, Oracle Cloud Storage, Microsoft Azure Storage and Amazon S3.

  1. It consists of several distributed resources, but still functions as one, either in a cloud architecture of federated or cooperative storage.
  2. Highly fault-tolerant via redundancy and data distribution.
  3. Extremely durable through the manufacture of copies of versions.
  4. Ultimately, it is usually compatible with data replication advantages.
  5. Companies just need to pay for the storage they actually use, normally an average of a month's consumption. This does not indicate that cloud storage is less costly, rather that operating costs are incurred rather than capital expenses.
  6. Cloud storage companies can cut their energy usage by up to 70 percent, making them a greener company.
  7. The provision of storage and data security is inherent in the architecture of object storage, so the additional infrastructure, effort and expense to incorporate accessibility and security can be removed depending on the application.
  8. Tasks for storage management, such as the procurement of additional storage space, are offloaded to the service provider 's obligation.
  9. It provides users with immediate access of wide variety of tools and software housed in another organisation's infrastructure through a web service interface.
  10. As there are usually 2 or 3 separate backup servers located in different locations across the globe, cloud storage may be used as a natural disaster proof backup.
  11. With the WebDAV protocol, cloud storage can be mapped as a local drive. For organisations with several office locations, it may act as a central file server.

Data security

  • Data storage outsourcing increases the surface area of attack.
  • It is processed at more locations after information has been dispersed, raising the likelihood of unauthorized physical access to the data. For example , in the case of the disposal of old computers, the reuse of drives, the reallocation of storage space. 
  • The way data is replicated depends on the quality of service a customer prefers and the service delivered. It will maintain confidentiality when encryption is in effect. When disposing of data (on a disc), crypto-shredding can be used.
  • The number of persons who may be compromised (e.g., bribed, or coerced) with access to the data increases significantly. As for the sharing of multiple cloud data with multiple users, a large number of keys must be distributed to users for decryption through secure channels, and users must also store and manage it securely on their devices. It takes very costly safe storage to store these keys.
  • It increases the number of networks the data travels over.
  • It is possible for other customers to access the data by sharing storage and networks with many other users or customers. Sometimes due to wrongdoing, defective equipment, a malfunction, and sometimes due to criminal purpose. With encryption technology, the possibility of making data read during transmission can be mitigated. It is the role of the transit encryption in order to safeguard the data as it is transferred to and from the cloud service. In-rest encryption protects the data stored by the service provider. Both forms of encryption security can be offered by encrypting data in an on-site cloud service on-ramp scheme.

Longevity

  • Companies are not permanent and they may modify the services and goods they offer. Data storage outsourcing to another business requires careful investigation and nothing is ever assured. 
  • When a business ceases to exist or its circumstances change, contracts set in stone can be worthless. Companies are willing to:
  • Expand their concentration and modify it.
  • Be absorbed by other bigger firms.
  • To be bought by a company based in or moved to a country that refuses compliance with export restrictions and thus needs a transfer.
  • Suffering from an unrecoverable tragedy.

Accessibility

  • Depending on how much a client is willing to invest on WAN bandwidth, outsourced storage efficiency is likely to be lower than local storage.
  • Reliability and accessibility depend on the availability of the wide-area network and the extent of precautions taken by the service provider. Hardware as well as different algorithms used should be focused on reliability.

A multiplicity of data storage is a given.

  • Users with unique record-keeping requirements, such as public entities that must maintain electronic records in compliance with the law, can face cloud computing and storage complications.

Suggested Solution to Cloud Problems

  • To prevent such problems, there are many choices available. One choice is to use a private cloud (there are also services that provide private cloud storage) instead of a public cloud. 
  • Another choice is to ingest data inside our on-site infrastructure in an encrypted format where the key is kept.
  • Access is also achieved using on-premise cloud storage gateways. These gateways not only have options for encrypting and compressing data prior to transfer, but also for mirroring storage through various cloud storage providers and removing the possibility of shutdown by a single provider. 
  • Gateways also provide the option of caching data on a recently used on-premise algorithm. Data is cached and fetched in the most useful form along with data analytics instead of just recently used form.

Types of Cloud Computing

Cloud computing itself has different forms, as per different needs and in different situations.

  • First thought comes to mind when we ask about the cloud, a majority of people would say it is an actual cloud or anything related to weather. 
  • Cloud computing is not a new concept in IT field. In simple term, cloud computing is a model which widely available, convenient network access to share pool of computing resources like servers, storage, application with minimal efforts.
  • Cloud computing involves using internet hosting rather than local severs, to make data and services easily accessible across locations and devices. 
  • It is a system where most businesses and people work from more than one computing device. Cloud computing can refer to either the applications or services delivered through the internet as well as to the software and hardware that facilitate these services. 
  • Commercial, public cloud services include Amazon’s EC2 (Elastic Compute Cloud), Microsoft’s Azure, and Google’s suite of apps including Gmail, Google Docs, and Google Calendar.

Types of Cloud Computing

  • Private cloud services exist solely by an organization which either manages the service itself, or has it managed by a third party. The examples discussed above all refer to versions of public clouds, accessible to the public and managed by a host organization, which sells these services.
  • Community clouds are shared by several organizations with a community that may share goals or concerns. Government or G-Cloud is a specialized example of this – one agency may provide a cloud service to a variety of other agencies under the same organizational umbrella.
  • There are also hybrid clouds, which combine public and private offerings to allow information exchange and even application compatibility across many different and disparate cloud service offerings. Hybrid cloud and its ability to utilize third party cloud providers makes this type of cloud especially flexible, and perfect for scaling to different needs.
