CLOUD COMPUTING ARCHITECTURE:Top Cloud Computing Applications in



Cloud computing is the delivery of on-demand computing services — from applications to storage and processing power — typically over the internet and on a pay-as-you-go basis.

Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.


History of cloud computing?

Cloud computing as a term has been around since the early 2000s, but the concept of computing-as-a-service has been around for much, much longer — as far back as the 1960s, when computer bureaus would allow companies to rent time on a mainframe, rather than have to buy one themselves.

These ‘time-sharing’ services were largely overtaken by the rise of the PC which made owning a computer much more affordable, and then in turn by the rise of corporate data centers where companies would store vast amounts of data.

But the concept of renting access to computing power has resurfaced again and again — in the application service providers, utility computing, and grid computing of the late 1990s and early 2000s. This was followed by cloud computing, which really took hold with the emergence of software as a service and hyperscale cloud computing providers such as Amazon Web Services.

How Does Cloud Computing Work

Rather than owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider.

One benefit of using cloud computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it.

In turn, providers of cloud computing services can benefit from significant economies of scale by delivering the same services to a wide range of customers.

What are the cloud computing services  that are available?

Cloud computing services in the IT industry are numerous cover, from the basics of storage, networking, and processing power through to natural language processing and artificial intelligence as well as standard office applications. Pretty much any service that doesn’t require you to be physically close to the computer hardware that you are using can now be delivered via the cloud.

Why is it called cloud computing?

A fundamental concept behind cloud computing is that the location of the service, and many of the details such as the hardware or operating system on which it is running, are largely irrelevant to the user. It’s with this in mind that the metaphor of the cloud was borrowed from old telecoms network schematics, in which the public telephone network (and later the internet) was often represented as a cloud to denote that the just didn’t matter — it was just a cloud of stuff. This is an over-simplification of course; for many customers location of their services and data remains a key issue.

Examples of cloud computing?

Cloud computing underpins a vast number of services. That includes consumer services like Gmail or the cloud back-up of the photos on your smartphone, though to the services which allow large enterprises to host all their data and run all of their applications in the cloud. Netflix relies on cloud computing services to run  its video streaming service and its other business systems too, and have a number of other organisations.

Cloud computing is becoming the default option for many apps: software vendors are increasingly offering their applications as services over the internet rather than standalone products as they try to switch to a subscription model. However, there is a potential downside to cloud computing, in that it can also introduce new costs and new risks for companies using it.

Companies are experiencing an unprecedented burden on their IT infrastructure as they struggle to meet growing customer expectations for fast, reliable, and secure services. As they try to increase the processing power and storage capabilities of their IT systems, often these companies find that the development and maintenance of a robust, scalable, and secure IT infrastructure is prohibitively expensive.

Luckily, there is another option; instead of acquiring extra hardware, your company can embrace cloud computing. Cloud computing is a rapidly-growing industry which allows companies to move beyond on-premise IT infrastructure and, instead, rely on internet-based services. Cloud-based providers often offer services such as software, storage, and processing at affordable prices. In fact, your company can save up to 30% by implementing a cloud-based solution.

Cloud computing is offered in three different service models which each satisfy a unique set of business requirements. These three models are known as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).


3 service models of cloud computing 1

Software as a Service offers applications that are accessed over the web and are not managed by your company, but by the software provider. This relieves your organization from the constant pressure of software maintenance, infrastructure management, network security, data availability, and all the other operational issues involved with keeping applications up and running. SaaS billing is typically based on factors such as number of users, usage time, amount of data stored, and number of transactions processed. This service model has the largest market share in cloud computing; according to Gartner, its sales will reach 117 billion USD by the year 2021 Current applications for SaaS include Field Service solutions, system monitoring solutions, schedulers and more.

Platform as a Service is halfway between Infrastructure as a Service (IaaS) and Software as a Service (SaaS). It offers access to a cloud-based environment in which users can build and deliver applications without the need of installing and working with IDEs (Integrated Development Environments, which are often very expensive. Additionally, users can often customize the features they want included with their subscription. According to Gartner, PaaS has the smallest market share of the three service models, with a projected revenue of 27 billion USD by the year 2021[2]. In today’s market, PaaS providers offer applications such as Microsoft Azure (also IaaS), Google App Engine, and Apache Stratos.

Infrastructure as a service offers a standardized way of acquiring computing capabilities on demand and over the web. Such resources include storage facilities, networks, processing power, and virtual private servers. These are charged under a “pay as you go” model where you are billed by factors such as how much storage you use or the amount of processing power you consume over a certain timespan. In this service model, customers do not need to manage infrastructure, it is up to the provider to guarantee the contracted amount of resources and availability. According to Gartner, this service model is forecasted to grow by 35.9% in 2018[2]. IaaS services offered today, include Google Cloud Platform and Amazon EC2.

Cloud computing has been around for quite some time now; however, it will continue to evolve as faster and more reliable networks offer increased benefits to service providers and consumers alike. With these advancements, there are growing opportunities to develop business models in an increasingly-connected economy.

Open Smartflex is the only holistic CIS solution that spans across the whole business lifecycle of Smart Utilities and runs on any service model and any cloud provider. It has a Customer Information System (CIS) at its core and has been extended with superior capabilities in four dimensions: on the metering side, with Meter Data Management (MDM) features; on the customer side with Customer relationship management (CRM) with digital customer engagement features such as self-service portal; on the field dimension with Mobile Workforce Management features; and, finally, with the Analytics dimension, all of them streamlined for mobility.

Benefits Of Cloud Computing

The exact benefits will vary according to the type of cloud service being used but, fundamentally, using cloud services means companies not having to buy or maintain their own computing infrastructure.

No more buying servers, updating applications or operating systems, or decommissioning and disposing of hardware or software when it is out of date, as it is all taken care of by the supplier. For commodity applications, such as email, it can make sense to switch to a cloud provider, rather than rely on in-house skills. A company that specializes in running and securing these services is likely to have better skills and more experienced staff than a small business could afford to hire, so cloud services may be able to deliver a more secure and efficient service to end users.

Using cloud services means companies can move faster on projects and test out concepts without lengthy procurement and big upfront costs, because firms only pay for the resources they consume. This concept of business agility is often mentioned by cloud advocates as a key benefit. The ability to spin up new services without the time and effort associated with traditional IT procurement should mean that is easier to get going with new applications faster. And if a new application turns out to be a wildly popular the elastic nature of the cloud means it is easier to scale it up fast.

For a company with an application that has big peaks in usage, for example that is only used at a particular time of the week or year, it may make financial sense to have it hosted in the cloud, rather than have dedicated hardware and software laying idle for much of the time. Moving to a cloud hosted application for services like email or CRM could remove a burden on internal IT staff, and if such applications don’t generate much competitive advantage, there will be little other impact. Moving to a services model also moves spending from capex to opex, which may be useful for some companies.

Top Cloud Computing Applications in 2020

1. Platform as a Service (PaaS) and Infrastructure as a Service (IaaS)

Two popular forms of cloud computing are PaaS or Platform as a service and IaaS or Infrastructure as a service. In the PaaS model, the hardware and software tools are provided to the users by a third party, generally for application development. The hardware and software are hosted by the provider.

In the IaaS model, cloud computing is provided on virtualized computing resources via the internet. The IaaS model is quite popular among companies as it cuts costs on investing and managing an entire IT structure since pay-per-use schemes are available for cloud computing services on the internet.

PaaS is also used with the same cost-cutting philosophy, along with boosting the speed of developing and deploying applications on a ready-to-use platform. Both these cloud computing applications have made it much easier for businesses to be productive as well as cost-effective.

2. Hybrid Cloud Approach

While deploying an application, it is important to deploy it in a limited environment to test out the workload and the comfort of using the application. Creating this environment is costly and would be a complete waste if the application fails. Hence, many companies use the hybrid cloud approach, which creates a platform for infrastructure and applications.

During limited peak usage, a hybrid cloud can expand – a feature that is preferred over hosting of large infrastructures. You can even expand on the various services based on the pay-per-use service features provided by Hybrid cloud services.

3. Testing and development

Cloud computing applications can help in creating a wonderful test and development environment for many developers. Traditionally, such an environment would have required time, a hefty budget for setting up the physical assets, and manpower. It is clear that setting up such an environment is not especially cost-effective and will stretch the deadlines and budget for a project.

However, with the help of cloud computing, you can have all these resources delivered to you almost instantly with a comparatively lower cost. This feature can also be combined with the automatic allocation of virtual and physical resources.

4. Big data analysis   

Big data analysis means the use of advanced and diverse analytical techniques on large data sets (can be terabytes or zettabytes). These data sets can be structured, unstructured, or semi-structured. One of the biggest feats of cloud computing is its contribution to big data analysis. Due to the storage facility offered by Cloud, people can now tap into unstructured, semi-structured, and structured data and convert them into business value.

By analyzing this data, businesses can find out market trends, buying patterns, and consumers and use this knowledge for targeted marketing and advertisements. Social media often uses big data analysis to understand the behavioral patterns of users and gain meaningful insight about them and suggest tailored recommendations.

5. Storage

Storage of data locally has always been a bit of a hassle. As we grew technologically, we required more and more space to store data. For example, if we talk about something as simple as a game – a 1990s game would only require about 8MB storage while games after 2017 would probably require above 30GB of space.

Nowadays, people can use cloud to store and access their files. You can store it from multiple devices and access the file from these devices as well as use other cloud-based services. Not only is storage on cloud convenient, but it also comes with high speed, benefits of scalability, and has integrated security too.

The storage is almost unlimited against a specific amount paid, and there is no need for daily maintenance of the data. Companies can store data on the premises or off-premises based on their compliance requirements. It is also stored by the third party based on customer specifications.

6. Recovery

Traditionally, due to the lack of proper cloud-based services, recovery was difficult or almost near impossible. Companies used to rely on different storage tools so that any loss of data can be retrieved from another storage. It wasn’t a very cost-effective process. There were rigid procedures for recovery, and the fixed assets required regular maintenance.

However, with the help of cloud, disaster recovery solutions have become more cost-effective. Disaster recovery solutions in cloud help in speeding up the recovery process from a mesh of varying physical locations at a much cheaper cost than traditional, locally placed disaster recovery systems.

7. Backup

Backing up data is a complicated process, and many computer scientists and engineers are always trying to modify and improve it. Previously, a set of drives or tapes were used. Data was manually collected and dispatched to the backup facility. This came with a host of problems, like the loss of data between the originating site and the backup site.

One of the common problems was running out of backup media. Human errors were often common too. Plus, recovery from the backup devices took a lot of time. With the use of cloud-based backup services, it is possible to dispatch the data automatically from any location using a wire. It is a secure means to activate the backup process. The capacity of the cloud server is not an issue, and the backup can be readily available from any device as well, making it so much more convenient.
