Complex Connections and Computations with Cloud Computing

Introduction:

Cloud computing means storing and accessing the data and programs over the internet rather than the computer’s hard disk. The data can be anything such as music, files, videos, images, documents, and many more. The user can access the data from anywhere just with the help of an internet connection. To access the cloud, the user should authenticate with ID and password for security reasons and safety purposes. The speed of transfer depends on various factors such as internet speed, the capacity of the server, and many more. The word ‘cloud’ is used as a metaphor for ‘the Internet,’ so the phrase cloud computing means a type of Internet-based computing.

The cloud enables the data center to operate like the Internet and computing resources to be accessed and shared as virtual resources in a secure and scalable manner. Cloud computing networks are large groups of servers and cloud service providers that usually take advantage of low-cost computing technology, with specialized connections to spread data-processing tasks across them. This shared IT infrastructure contains large pools of systems that are linked together. Virtualization techniques are often used to maximize the power of cloud computing. It can be defined as delivering computing power as a service over a network rather than physically having the computing resources at the customer location.

The availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture, and autonomic utility computing has led to growth in cloud computing. In the future, all web or mobile applications will be available on the cloud.

Characteristics of Cloud Computing: Agility, High availability and reliability, High Scalability, Multi-Sharing, Device and Location Independence, Maintenance, Low Cost, Services in a pay-per-use model, Broad network access, resource pooling, and Rapid elasticity or expansion

Types of Service Models:
  • Infrastructure as a Service (IaaS): It is one of the primary services which provides access to computing resources in a virtualized environment i.e. the server is running in the service provider’s data centers but is fully managed by the customer. The greatest benefit of IaaS is extra capacity, which can be accessed on demand for long-term or short-term needs. The reason for choosing IaaS is that it is easier, faster, and cost-efficient which reduces the burden of the organizations. It provides computing infrastructure like virtual server space, network connections, bandwidth, load balancers, and IP addresses. IaaS-cloud providers supply these resources on-demand from their large pools of equipment installed in data centers

  • Platform as a Service (PaaS): It is a developer programming platform which is created for the programmer to develop, test, run and manage the applications. A developer can write the application as well as deploy it directly into this layer easily. It is used to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development. This helps the user by providing the facility to make, publish and customize the software in the hosted environment
  • Software as a service (SaaS): It is a method for delivering software applications over the Internet, on-demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet or PC. SaaS is a software delivery method that provides access to software and its functions remotely as a Web-based service.  SaaS is compatible with all internet-enabled devices. SaaS is also known as "On-Demand Software"


Types of Deployment Models:
  • Public Cloud: It is used by the public. These clouds are accessed through the internet by users. These are open to the public and their infrastructure is owned and operated by service providers. Public cloud is the classic cloud computing model, where users can access a large pool of computing power over the internet (whether that is IaaS, PaaS, or SaaS). Public clouds are typically cheaper than private and hybrid cloud solutions
  • Private Cloud: It is owned by a specific entity or an Organization and normally used by that entity or one of its customers. It allows the accessibility of systems and services within the organization. On-premise private clouds, also known as internal clouds, are hosted within one’s own data center. Externally hosted Private Cloud is hosted externally with a cloud provider

  • Hybrid clouds: It’s a combination of both public and private services. This type of model allows the user more flexibility and helps optimize the user's infrastructure and security. By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options and helps optimize your existing infrastructure, security, and compliance
  • Community Cloud: Here, computing resources are provided for community and organizations.  The infrastructure is owned jointly by different organizations. The organizations may have a similar set of requirements, policies, and customer base. This model helps to reduce the costs

Essentials:
  • Serverless Computing: Serverless computing is a Cloud Computing model in which the platform will dynamically determine and manage the allocation of required infrastructure and automatically provisions and de-provisions the infrastructure to support the application. With this, the cloud instances are no longer allocated to sit idle till called upon to kickstart the applications and other functions. Hence, the Serverless Architecture also is known as “Function as a Service” (FaaS). It is a service-hosted remote procedure call that leverages serverless computing to enable the deployment of individual functions in the cloud that runs in response to events
  • Mobile Backend as a service (MBaaS): In this, web application and mobile app developers are provided with a way to link their applications to cloud storage and cloud computing services with application programming interfaces (APIs) exposed to their applications and custom software development kits (SDKs)
  • Multicloud: It is like a hybrid cloud because the customer is using more than one cloud service. A multi-cloud environment can include only public clouds, only private clouds or a combination of both public and private clouds

  • Everything as a Service (EaaS): Cloud Computing sees continued growth for all its cloud-based services and solutions. Most of these services are already well established with Infrastructure, Platform, and Software as a Service (IaaS, PaaS, and SaaS) all predicted to account for a more significant portion of IT segments in near future known as Everything as a Service
  • NoOps (No Operations): NoOps is the concept that an IT environment can become so automated and abstracted from the underlying infrastructure that there is no need for a dedicated team to manage the software-in-house. The more underlying technologies are abstracted, and less operational tasks are required and hence the term NoOps
  • Virtualization: It is the creation of a virtual version of something, such as a server, a desktop, a storage device, an operating system or network resources. In other words, Virtualization is a technique, which allows sharing a single physical instance of a resource or an application among multiple customers and organizations
  • Cloud Automation: It is a method of provisioning, deploying and decommissioning using a good automation software. Without automation, provisioning capacity is a manual process, and managing all those pooled resources would be too inefficient

Advantages:
  • Worldwide Access, More Storage, Easy Set-Up, Fast, Secure, and Data Safety
  • Pay-per-use Model, Convenient, Adaptable, and Multitenant
  • Reliable, Cost, Automatic Updates, Performance, Flexible and Scalable

Disadvantages:
  • Security, Privacy, Loss of Control, Internet Reliance, and Data Protection
  • Regulatory and Compliance Restrictions, Costs and Mobilization


Future:
Within the next couple of years, most of the existing non-cloud apps will move to the cloud. Today’s computing landscape shows companies not only adopting cloud but using more than one cloud environment. It’s truly indicating that there will be a constant provocative rise and growth in the Cloud Computing industry and its subsidiaries.
Applications:
  • Entertainment, Social Media, Logistics, Documents, and Spreadsheets
  • Banking, CRM and PPT’s, HR, Payroll, Accounting, and Inventory Management
