What Is Cloud Computing? An Overview Of The Cloud

Plus, cloud providers’ security teams are known as top experts in the field. Multicloud is the use of multiple cloud computing services in a single heterogeneous architecture to reduce reliance on single vendors, increase flexibility through choice, mitigate against disasters, etc. It differs from hybrid cloud in that it refers to multiple cloud services, rather than multiple deployment modes . Organizations choose multicloud to avoid vendor lock-in, to have more services to choose from, and to access to more innovation. But the more clouds you use—each with its own set of management tools, data transmission rates, and security protocols—the more difficult it can be to manage your environment. PaaS provides the ability to create and manage custom cloud applications.

You access these services and manage your account through a web browser. SaaS is a software delivery model in which the cloud provider hosts the customer’s applications at the cloud provider’s location. Rather than paying for and maintaining their own computing infrastructure, SaaS customers take advantage of subscription to the service on a pay-as-you-go basis.

Data Storage

In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. Cloud users do not manage the cloud infrastructure and platform where the application runs. This eliminates the need to install and run the application on the cloud user’s own computers, which simplifies maintenance and support.

Your financial situation is unique and the products and services we review may not be right for your circumstances. We do not offer financial advice, advisory or brokerage services, nor do we recommend or advise individuals or to buy or sell particular stocks or securities. The cloud can help your business save money, become more agile, and operate more efficiently.

  • This enables the business to reallocate IT operations costs away from hardware/software spending and from personnel expenses, towards meeting other goals.
  • For users, moving critical business activities to the cloud leads to greater productivity.
  • Cloud SQL Fully managed relational database service for MySQL, PostgreSQL, and SQL Server.
  • Financial services companies are using the cloud to power real-time fraud detection and prevention.
  • Cloud applications differ from other applications in their scalability—which can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand.

Retailers are using the cloud and cloud computing to gain faster customer insights, improve performance and make the best use of existing resources. One can share single physical instance of hardware, database and basic infrastructure. Cloud Computing offers online development and deployment tools, programming runtime environment throughPaaS model. PaaS provides the runtime environment for applications, development and deployment tools, etc.

Before the cloud became a viable alternative, companies were required to purchase, construct, and maintain costly information management technology and infrastructure. Companies can swap costly server centers and IT departments for fast Internet connections, where employees interact with the cloud online to complete their tasks. Cloud computing is far more than just accessing files on multiple devices. Thanks to cloud computing services, users can check their email on any computer and even store files using services such as Dropbox and Google Drive. Infrastructure-as-a-service involves a method for delivering everything from operating systems to servers and storage through IP-based connectivity as part of an on-demand service.


A stack refers to the combination of frameworks, tools, and other components that make up cloud computing’s under-the-hood infrastructure. This includes Infrastructure as a Service , Platform as a Service , and Software as a Service modules. These services provide customers with varying levels of control and responsibility in their cloud environment. Hybrid cloud is the combination of one or more public and private clouds. Let’s say you work in an industry that must adhere to very strict data privacy regulations. While you don’t want to host data that is subject to regulation in the cloud, you want to access it as if it was.

Think of SaaS as the off-the-shelf option for getting into It’s usually a standard set of offerings that are available for immediate implementation on a pay-as-you-go basis. You may already be using SaaS in your personal life without really thinking about it. If you use a web-based email or calendar service, then you are using a form of SaaS.

Using PaaS is ideal when you have lots of developers working on the same project, or if you’re using several vendors. In many ways it helps simplify the creation and rapid deployment of apps. It is very difficult for the customers to switch from oneCloud Service Provider to another. Anything-as-a-Service is yet another service model, which includes Network-as-a-Service, Business-as-a-Service, Identity-as-a-Service, Database-as-a-Service or Strategy-as-a-Service. What happens if you’re somewhere without an internet connection and you need to access your data?

Measures to protect this data include two-factor authorization , the use of VPNs, security tokens, data encryption, and firewall services, among others. Hybrid clouds are, as the name implies, 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. Cloud computing offers enterprise developers quick access to tools and platforms for building and testing applications, speeding up time to market. Cloud computing is the on-demand availability of computing resources as services over the internet.

Von Laszewski, Gregor, et al. “Comparison of multiple cloud frameworks.”, IEEE 5th International Conference on Cloud Computing , 2012. For instance, sworn translators working under the stipulations of an NDA, might face problems regarding sensitive data that are not encrypted. Due to the use of the internet, confidential information such as employee data and user data can be easily available to third-party organisations and people in Cloud Computing.

Cloud Roadmap

Virtualization software separates a physical computing device into one or more “virtual” devices, each of which can be easily used and managed to perform computing tasks. With operating system–level virtualization essentially creating a scalable system of multiple independent computing devices, idle computing resources can be allocated and used more efficiently. Virtualization provides the agility required to speed up IT operations and reduces cost by increasing infrastructure utilization.

Hybrid clouds connect infrastructure and applications between cloud-based resources with existing resources not located in the cloud. This approach gives your business greater flexibility and deployment options. Some integration and data management providers also use specialized applications of PaaS as delivery models for cloud computing data. IPaaS enables customers to develop, execute and govern integration flows. Under the iPaaS integration model, customers drive the development and deployment of integrations without installing or managing any hardware or middleware. DPaaS delivers integration—and data-management—products as a fully managed service.

When a company chooses to “move to the cloud,” it means that its IT infrastructure is stored offsite, at a data center that is maintained by the cloud computing provider. An industry-leading cloud provider has the responsibility for managing the customer’s IT infrastructure, integrating applications, and developing new capabilities and functionality to keep pace with market demands. Public clouds are hosted by cloud service providers, and distributed over the open internet. Public clouds are the most popular and least expensive of the three, and frees customers from having to purchase, manage, and maintain their own IT infrastructure.

For customers, cloud computing offers more agility, scale, and flexibility. Instead of spending money and resources on legacy IT systems, customers are able to focus on more strategic tasks. Without making a large upfront investment, they can quickly access the computing resources they need—and pay only for what they use. In general, the cloud is as secure as any other internet connected data center. If anything, you can expect better security from cloud service providers—the big ones in particular—as it is all but guaranteed that their security staff is better than anyone that you can assemble.

Autonomic computing automates the process through which the user can provision resources on-demand. By minimizing user involvement, automation speeds up the process, reduces labor costs and reduces the possibility of human errors. Platform as a service is a cloud infrastructure built on IaaS that provides resources to build user-level tools and applications. It provides the underlying infrastructure including compute, network, and storage resources, as well as development tools, database management systems, and middleware.

How Cloud Consumption Works

A cloud provider maintains the hardware and computing infrastructure that organizations can lease, typically for a monthly fee. You can choose your options that can include a fixed offering or a mix of storage, software and platform options. Cloud computing encompasses business applications, and data storage, networking and processing capabilities, too. It enables organizations of all sizes to take advantage of powerful analytical technologies such as natural language processing and artificial intelligence. If computing services are available in the marketplace, they’re almost certainly available via the cloud. Today, cloud computing has moved to the center of many organizations’ technology strategies.

Reduce the need for additional personnel to manage software updates or version compatibility with different operational systems and databases. Applications such as e-mail, web conferencing, customer relationship management execute on cloud. Let’s say you’re visiting a client, and you realize that you left the proposal that you stayed up all night to complete. In a world without the cloud, the only way you’re getting that proposal is by physically retrieving it.


You can see the obvious drawback is the cost of setting up the cloud computing infrastructure. The up-front expenses of hardware, real estate and staffing can be significant. Even if you opt to contract a private cloud provider, cost can be significantly higher. But if you’re an enterprise-level company where security and privacy are critical, then it’s an option you will want to explore. Private cloud hosting offers isolated firewalled infrastructure that improves security. In addition, cloud providers offer many security mechanisms and technologies to help build secure applications.
