SaaS (Software as a Service) SaaS is the bottom level of the cloud stack that offers you a cloud-based software for a monthly or yearly fee. After payment, the cloud vendor provides you access to the software over the Internet. This is a software solution that you can use from your browser. No additional software needs to be installed. You can enjoy the service using their user interfaces without much upfront cost. Popular SaaS products include DropBox and Salesforce. These are great options for those who want a complete cloud software solution without paying much. Small and medium businesses that have just started and do not have enough funds to spend on their IT infrastructure can use SaaS. The SaaS providers also offer good customer support if you run into any troubles. In SaaS, all the software infrastructure, middleware, and application data are stored in the provider’s data center. Using a service agreement, the vendor ensures the security of your app data. The best part about SaaS is that you do not necessarily have to be a tech wiz to use it. Benefits of using SaaS You can access the SaaS software using a web browser, such as Google Chrome from a laptop, desktop, tablet, or smartphone. It is easy to use, flexible, and can be scaled up or down. The pay-as-you-go model helps you save costs. New releases and upgrades are provided to users as soon as it is available. The upgrading costs are minimal. Learn more: Top 7 Cloud Computing Applications in Real World 4.

The similarity between cloud computing and grid computing is uncanny. The underlying concepts that make these two inherently different are actually so similar to one and another, which is responsible for creating a lot of confusion. Both cloud and grid computing aims to provide a similar kind of services to a large user base by sharing assets among an enormous pool of clients. Both of these technologies are obviously network-based and are capable enough to sport multitasking. The availability of multitasking allows the users of either of the two services to use multiple applications at the same time. You are also not limited to the kind of applications that you can use. You are free to choose any number of applications that can accomplish any tasks that you want. Learn more about cloud computing applications. Now the way each of these technologies makes the resources available to the user base is actually very different. Grid computing aims to make all the available resources virtual, meaning all the computing resources would be made available on a grid to store vast amounts of data. Cloud computing, however, is very different from grid computing in this regard. Cloud computing never lets any application access the available resources directly. Instead, all the resources are made available for use by any application via the use of the internet. Another critical difference between grid and cloud computing is that the available resources are distributed to the computers connected to the specific grid in grid computing. Whereas in cloud computing, the management of all the available computing resources is done in a central unit. That was a very brief overview of what makes each of these methods of computing unique. In order to understand grid computing vs. cloud computing in a holistic way, we must first take a look at them individually.  Learn Online Software Development Courses online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. Grid Computing With the help of a number of computers all linked together on a network, grid computing aims to process a massive volume of data by pooling in all the available computing power from all the computers on the network. If you employ grid computing to solve a problem, grid computing would instruct all the available processing units currently on the grid to work on the same issue, thus reducing the amount of time taken to solve the problem simultaneously.  Essentially, the definition of grid computing would be that it is a massive network of computers all connected with each other, all working in harmony to solve a common problem. The solution to the problem is found out by dividing the problems into smaller units known as grids. Grid computing follows a distributed architecture meaning the tasks given to any computer over the grid are managed and given meticulously to avoid any clashes and minimize the overall time is taken (there is no time dependency).  Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Cloud Computing Cloud computing is the type of computing that is accomplished via the help of the internet. Any application which is running on the cloud computing setup cannot access the resource pool directly. Instead, the application must interact with the internet to gain access to any of the available computing power. It is definitely a testament to the modern advancement which have been achieved in the 21st century. Cloud computing works best for remote access to any IT resource which might not be available but, at the same time, is very crucial for a computing problem to be solved. Cloud computing allows for on-demand access to a vast resource pool, which is dynamically allocated. Since there is just a need for one main computer to handle resource allocation; thus, the cost of setting up the operations is also reduced. Cloud computing allows users to only use the applications they want without worrying about any of their own personal data. Essentially you pay only for what you use and what you need.  Must Read: Cloud Computing Project Ideas & Topics Difference Between Grid and Cloud Computing Now that we have understood the particular meaning of the two terms, we can now pit grid computing vs. cloud computing, head to head to understand what differences lie there: 1. The difference in technology In Grid computing, the task at hand is broken down into smaller problems. Through a distributed network, the tasks are shared among the network of interconnected computers. Whereas, in cloud computing, there is just one central computing unit that takes care of the distribution of all the available resources. The resources can only be accessed with the help of the internet. 2. The difference in the way of their functioning The primary function that grid computing is used for is scheduling jobs, where the available resources are divided and distributed into a number of small tasks that every computer on the grid is tasked to do. After completing all these little tasks, all the allocated resources are acquired back by the main machine. Cloud computing, on the other hand, behaves on a need basis. Whenever there is a need for resources, the central computing unit allocates all the available resources and takes them back when the task is completed.

The difference in their application Cloud in cloud computing is actually a reference to the internet. The primary use of cloud computing is to ask for the resources whenever the need for them arises without having to buy either the software or the hardware by yourself. The cloud takes care of all resource allocation and management. Whereas, researchers actually use grid computing to perform academic research because the pooling of such a considerable amount of computing power in one place allows for a faster and an efficient way to handle massive amounts of data. Not only does grid computing can handle massive amounts of data, but it can perform the required actions and provide the desired results. upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   4. The difference in resources Grid computing requires the presence of physical hardware or software to be connected on the grid. The location of these resources, however, is not important as long as they all are connected. In cloud computing, there is just one central unit that takes care of everything.  In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Checkout: Future Scope of Cloud Computing What Next?

Cloud computing architecture includes various cloud computing components, bundled up to form a fully functional system. It can broadly be classified into two parts: Front End It is the user interactive platform, and it’s ideally for the users to provide their requirements. It includes local networks, browsers, and web APIs and development kits. The front end provides a menu for the user to convey their needs and perform tasks on the cloud. The software for the client’s end consists of client-based applications and browsers. The main hardware part at the client’s end is the Client Network. The front end is easy to use, and the format is available for users to get hassle-free services. The user need not take care of the back end processes. Everything will be provided with a click. Back End The back end building of the cloud draws in the front end plan. It includes hardware and limits and is arranged on an inaccessible specialist. The cloud controls this back end cloud plan in the center. Back end cloud building should be generous and reliable, as it sustains the whole system using the cloud. The prime pieces of back end cloud building are:  Application: The application is a significant part of the back-end designing. It insinuates the UI that the back end offers to the end customer to send requests. This layer of the back end manages the client’s sales and necessities.  Organization: It is a captivated zone of back end cloud designing. Thus, it adds functions to the entire back end plan. The organization handles each endeavor that abruptly spikes for the disseminated registering system. A segment of the cloud organizations is application improvement in terms of condition, storage, and web organizations.  Cloud Runtime: The term ‘Cloud Runtime’ is the spot that associations run. No doubt, a cloud working structure. Absolutely when we make progressions with the assistance of virtualization programming, they are called Hypervisors. A hint of the basic hypervisors is Oracle Virtual Box, Oracle VM for x86, VMWare Fusion, etc.  Cutoff: Distributed capacity is the place where the data of a cloud application stands or resides. In any case, all of them have a typically submitted locale for passing on limits. A pattern of the instance of the cutoff is solid-state drives, hard drives, Intel Optane DC Persistent limit, etc. The specialist cover structure is taken care of in the cloud back end arranging. Additionally, especially in a circumnavigated area taking care of the structure, the thing scatters drive as indicated by the necessities of the OS in the cloud to run swarm affiliations. Establishment: The motor that arranges all the cloud computing components is called structure. It wires the CPU, Motherboard, Graphics Processing Unit (GPU), network cards, invigorating pro cards, and so on. The foundation models dependably rely on the uncommon loads of the customers. Must Read: Career in Cloud Computing Components of Cloud Computing Architecture There are several components of cloud computing: Hypervisor It is also known as Virtual Machine Monitor. It acts as a virtual operating system for the user, allowing them to manage the guest operating system to use the cloud. It consists of software, hardware, and firmware that combine and run the virtual machine to use the cloud. Management The administration programming assigns explicit assets to explicit undertakings and is answerable for the impeccable working of any cloud condition. In specialized terms, the executive is the ‘middleware,’ and it arranges between the front end and back end engineering in a distributed computing framework. The executive’s programming comprises different plans and the systems that help build the cloud exhibition. This administration programming gives numerous highlights, for example, on-time conveyance of capacity, legitimate security, untouched access, and numerous different offices. This is one of the significant pieces of Cloud Computing design. One of the significant highlights of this is the consistent examination, the executives of managing calamity, and emergency courses of action. Deployment Every cloud system needs to be deployed first. It consists of all mandatory installations and configurations for the cloud. There are three models of deployment to initiate it. SaaS – Software as a Service  Offering circulated processing organizations through approved programming or participation. In this transport model, the end-customers don’t need to buy or present any gear in their territories. PaaS – Platform as a Service PaaS model offers a phase that allows the end-customers to make and run similarly as administer applications on the cloud. In PaaS, an outcast master association empowers hardware and programming instruments. IaaS – Infrastructure as a Service  This model energizes PC hardware like frameworks organization development, laborers, accumulating, and worker ranch space as a help. It moreover fuses the movement of virtualization advancement and working system. Network The network is the most important component of the architecture. It binds the connection of the cloud. It connects the front end to the back end. Benefits of Cloud Computing Speed and Latency The cloud services increase latency, and hence, the speed increases. Speed is the need in today’s times. Cloud showers us with fast speed technology. Accessibility It allows us to work without portable digital tools. It increases thus, providing users access to cloud-based software through most browsers and devices. Cost-Efficient Pay for what you want! Cloud service providers have customized packages with full IT support. It reduces the cost and provides full customer support too. Flexibility It allows us to alter the bandwidth of the cloud. Thus, one can easily increase or decrease cloud capacity. Organizations adore this benefit of cloud providers. Security Organizations are worried about their data being stolen. Thus, cloud architecture provides great security with an almost null risk of vulnerability. Hardware damage can not let the data be hampered. Thus, your data is safe and secure with the cloud. Automatic Updates The regular design requires a lot of time and inner assets to oversee, keep up, and stay up with the latest. Sending refreshes expects frameworks to go under personal time and become inaccessible.

Read: Top Cloud Computing Models Explained Why are there different models? Different organizations tend to have very different performance requirements based on their business’ specific needs. The main reasons are the level of performance desired in terms of concurrency, costs, security, privacy, and control over the desired data.  For example, one of the most prominent reasons for choosing a specific cloud computing service is where the data center is located. These data centers or cloud computing hubs have tens of thousands of high performance servers to serve fast computing and storage needs of businesses. Thus, the cloud computing deployment models and strategy are first and foremost classified according to the location. This gives rise to four major types of deployment models. Check out upGrad’s Advanced Certification in Blockchain 4 Types of Cloud Deployment Models  1. Private cloud In the private cloud computing model, a proprietary environment is dedicated to your business. Computing and storage resources are extended via virtualized components, which may be on-premise or at the vendor’s data center. A private cloud provides superior levels of security and control to organizations because they can configure and manage the environment based on their specific business needs,  2. Community cloud A community cloud model is very similar to a private cloud setup. The only difference is that in a private cloud setup, the cloud computing infrastructure and servers are owned and managed by a single private entity. But in a community cloud model, several different organizations of similar size pool their resources together to share infrastructure costs, maintenance, operations, and deployment. But for the community model to work properly, the participatory companies should have similar security, privacy, and performance requirements.    3. Public Cloud In a public cloud, computing and storage resources are provided to the customer over the internet. Public cloud offers immense cost benefits because organizations can do away with costly on-site hardware deployment and maintenance. 4. Hybrid Cloud Hybrid cloud computing offers the best of both public and private worlds by straddling the two with a layer of proprietary software. With a hybrid model, it is possible to host the application in a secure environment while leveraging cost benefits and low time to market offered by the public cloud.  Must Read: Scope of Cloud Computing Classification of Cloud Deployment Models Based on Services 1. Infrastructure as a Service  IaaS requires the customer to install traditional applications on servers offered by the cloud platform provider. The customer is expected to manage all aspects of the application software and hardware. The capabilities of the software are identical to the same software deployed using on-premises hardware.   Benefits of IaaS Service Model IaaS Service Model offers time and cost savings since more installation and maintenance of IT software/ hardware happens in-house.  IaaS also offers better flexibility since the on-demand hardware resources can be more easily tailored to your specific needs.  The IaaS model, with its complexity, time, and cost savings, is especially valuable for large enterprises, which have large in-house IT teams that can build and manage the platform by themselves without having to rely on an external partner. The IaaS offers the desired flexibility to mold the platform according to their specific needs.  2. Platform as a Service The hybrid approach of the PaaS allows for the cloud vendor to provide the hardware and the software as a cloud service, and the vendor manages the hardware deployment, software installation, and software configuration. The customer, on the other hand, is responsible for managing, tuning, and optimizing the software.  Benefits of Platform as a Service The PaaS model is very popular since it provides the best of both worlds. The vendor is responsible for deployment and installation of hardware and software, while the customer manages the optimization, fine-tuning, and installation of the software and hardware updates.  PaaS provides flexibility as well as time savings for managing and deploying large development projects – managing the implementation of the platform and instant production. Security – The customer is responsible for managing data security protocols and taking application backups.   Also Read: Cloud Computing Ultimate Guide upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   3. Software as a Service  In SaaS, the cloud vendor provides all hardware and software, including all aspects of managing the hardware and software. This includes services such as software and hardware upgrades, security, availability, data safety, and performance optimizations.  Benefits of SaaS While being more costly than its IaaS and PaaS counterparts, SaaS provides immense benefits in terms of time saving and quick deployment. The customer does not need to be concerned with infrastructure and managing the software alignment. There is no need for installation or software maintenance. The vendor provides all the necessary software and hardware upgrades, including security.  Testing and deploying new software applications is quick and easy. The SaaS model is the most popular, and it is responsible for the rapid growth in the adoption of cloud computing services today.  An effective cloud deployment strategy needs to take into account the specific needs of the organization. Many organizations find it easy to deploy and use SaaS models that have low cost monthly subscription plans. As they scale out and build deeper in house capabilities, these organizations can then develop and set up the advanced capabilities, manpower, and technology needed. Moreover, the scalability and flexibility offered by cloud providers implies that organizations often work with multiple cloud vendors for provisioning and streamlining different workflows; this puts pressure on the vendors to provide superior performance and security because the competition is intense, and it is quite easy to cancel the cloud subscription and switch vendors within a cloud deployment strategy.  Conclusion Previously, organizations had expressed concerns with regards to data security and privacy for cloud deployment models, especially within a shared public cloud model. But these fears have not only been allayed, but the deeper pockets and technology expertise of major cloud vendors such as Amazon, Microsoft, Google, and IBM ensure the most advanced security protocols and layers to guarantee data safety and security. With these advancements in technology as well as the huge success and willingness shown by organizations to adopt cloud computing solutions for success and speed covey that it is a very exciting time to look ahead for cloud computing.  At upGrad, we offer the Advanced Certificate Programme in Cloud Computing program.

Cloud Deployment Models Private Cloud  Private Cloud is the first type of deployment model in cloud computing.  A private cloud is a cloud infrastructure that is operated just in a single organization. It can be managed internally or by third-party providers.  Private cloud needs physical presence, space allocation, hardware, and environmental controls. These factors involve capital expenditures.  It can be deployed by using Microsoft System Center, Vmware Vcloud, Openstack, Eucalyptus. Public Cloud In Public Cloud, the infrastructure and services are provisioned for open use by the general public. It may be owned, managed, by a business or a government agency. The devices exist on-premises of a cloud service provider. Public cloud features are: Hosted at the service provider site. Utilizes the shared infrastructure. Supports connectivity over the internet. It is cheaper than an enterprise private cloud. If you use an email client connected to Gmail, Outlook.com, or Yahoo, you are using a public cloud application. Various service providers for public cloud are AWS (Amazon Web Services), Microsoft Azure, Google Compute Engine, IBM SoftLayer, HP Helion Public Cloud Read: Cloud Computing Ultimate Guide Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Community Cloud The third type of cloud deployment model is Community Cloud. A community cloud is a shared environment in which several companies, or even individuals, gain the benefits of a public cloud by using private cloud-like controls and security. This kind of cloud infrastructure is provisioned for use by a particular consumer network (for instance, Insurance, Banks, Airlines). It may be owned, managed by one or more organizations inside the community. It may exist on or off-premises. Hybrid Cloud The fourth deployment model is the Hybrid Cloud. This cloud infrastructure is a composition of two or more cloud infrastructure (public + private). It is utilized to set up proprietary or standardized technology that empowers application and data portability. What is Object Storage? As an introduction to cloud computing, try to get this, just like we move photos from devices to a PC, – Simplify management and usage – Organize, protect and share photos, IT Cloud industry uses Object stores for similar reasons – To consolidate, organize and protect user data – To manage data and faster search. Traditional Storage used concepts of SAN (Storage Area Network) and NAS (Network Attached Storage). Object storage eases storage administrators from tiresome tasks like creating and managing the logical storage volumes, formatting, and managing RAID levels in case of any unfortunate event of storage device failure. In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Characteristics of Object Storage Linear Scalability – The storage can scale up to support billions of objects. Support for large files – in the object storage terminology, the supported single object sizes are in TBs (Terabytes). Web Friendly – Objects can be stored and retrieved using the Web User interface, HTTP-based, and RESTful API (Representational State Transfer, Application Programming Interface). Metadata and extensibility – Object storage adds metadata to the object, as controlled by the interface in use when it creates or rewrites it as an object. Geo Scale – Objects can be geographically replicated and distributed. No Locking – Objects can be edited, as there is no locking on write or create operations.

Prominent businesses prefer the cloud for their apps to serve, win, and retain customers. The demand for cloud computing is growing in all its forms. According to the Market Research Firm Gartner’s new market forecast, this growth is estimated to be 18% by 2020. The worldwide revenue has increased from 209 billion USD (United States Dollar) to 246.8 billion USD. Each company’s infrastructure is unique, and thus cloud computing service demands are different for every client. Cloud computing service providers supply cloud computing models based on customer’s demand suitable to the infrastructure and market.    There are different categories of cloud computing cost models depending on four major parameters viz.: fact, value, demand, and supply. Other several factors such as cloud technology, business strategy, competitive market environment, investment budget, and targeted customers are considered while mapping cloud cost models into different categories and strategies. There are three strategies for costing and a 3X3 matrix for the value that defines a conceptual framework to examine systematic cloud cost models. Check out our free courses to get an edge over the competition. What are the Cloud Cost Models? Cloud cost models are dynamic in nature as the supply and demand keep fluctuating. These depend on multiple characteristics and are auction-based, time-based, or cost-based. There are three cloud pricing strategies that are subjective (value), objective (fact), and market-based. Demand drives value-based cost; supply drives cost-based cloud model; whereas an equilibrium of both supply and demand drives the market-based cloud model. Check out upGrad’s Advanced Certification in Cloud Computing Cloud cost modeling has research challenges that include moving from pure cost-based to both value-based and cost-based cloud cost modeling. Other challenges are moving from statefulness to stateless pricing, transferring from mutable to immutable pricing, and developing cloud cost models that attract cloud customers. Sixty different cloud cost models are determined as per this analysis. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript   Let us understand what different cloud service cost models are: 1. Service-Based Cost Model It emphasizes value delivery with physical product-oriented pricing. Service-based cost models are used in banking, airline, travel, legal consultant, insurance, hospital, and so forth. The service-based model’s value is measured using the unit of a level, tier, per device, user, and priority. The value of this model can be identified and predicted.  Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) 2. Performance-Based Cost Model It is an arrangement in which the seller pays based on the actual performance of a cloud model or service as per M. McNair’s definition. It is connected to the client’s business outcome that relies on specific performance metrics. Examples of this model’s applications include telecom services such as mobile apps, multi-party video conferences, satellite connectivity.  Read: Cloud Computing Types 3. Customer Value-Based Cost Model It sets a price from a subjective view of a client focusing on the client’s value delivery. There are four categories of value-based cost models: perceived value, feature, psychological and hedonic-based model. The construction of these models is based on perception, sociology (large environment), psychology, and economics (utility). The customer value-based cost model maximizes the business’s profit and leads in the market.

Free Upfront and Pay Later Cost Model The competition among cloud service providers is increasing along with its demand. Many cloud service providers offer free upfront and pay later cost models to leverage their products with basic features to gain more customers and make profits from premium clients. Three cost models are available viz. free product cost on advertising, freemium, and razor and blades cost model. 5. Auction and Online-Based Cost Model Auction based cost model decides the pricing. As per Asuncion Monchan, an Auction is a market mechanism, operating under specific rules that determine whom one or more items will be awarded and at what price. It is relatively faster and transparent, with no backward and forward processing steps.   6. Retail-Based Cost Model It is based on a small number of customers that buy from physical locations/ retail outlets. It applies to the B2C (Business-to-Consumer) model. It has four subcategories of cost model: discount and allowances, product mixing, promotional and discriminatory pricing.

Expenditure Based Cost Model A cost is decided on using the application for a central component as a unit of charge. It has three types of cost models: cost-plus, target return, and percentage cost model. 8. Resource-Based Cost Model This cost model depends on the consumption of services. It is one of the categories of cost-based cost model strategy. Read our Popular Articles related to Software Development Why Learn to Code? How Learn to Code?

Utility-Based Cost Model As per Nayan B. Ruparelia’s definition, “Utility models are metered price models whereby your usage of the service is monitored, and you pay accordingly.” Customers need updated cloud models and resist accepting obsolete hardware-based costing. They demand renewation in contracts as per the metering of utility-based IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service) models. Cloud cost models vary as per unique discount options and frequent price cuts to attract customers.
