What is a ‘Cloud Computing Service’?

Cloud computing is an advanced technology, a remarkable platform that has the potential to transform the way organizations view and deal with IT operations. Cloud computing is the on-demand delivery of compute power, storage, database applications, and various other IT resources via the internet with pay-as-you-go pricing. In simple words it means a company or an individual uses someone else’s computing services (usually over the internet) instead of having to run that software on their own computers storing and accessing data and programs over the Internet.

Cloud computing is named as such because the information being accessed is found remotely in a virtual space or the ’Cloud’. Companies that provide cloud services enable users to store files and applications on remote servers and then access all the data via the Internet.

Examples of cloud services include Web-based e-mail services, online data storage, and backup solutions, document collaboration services, hosted office suites, database processing, managed technical support services and more.

 

How do cloud services work?

Cloud computing refers to sharing resources, software, and information through a network, in this case, the Internet. The information is stored maintained and controlled by a cloud computing provider on physical servers. Cloud computing services utilize server and storage virtualization extensively to allocate/reallocate resources rapidly.

Resources are pooled and shared among multiple users to gain economies of scale. These resources are accessed via web-browser or thin client using a variety of networked devices (computer, tablet, smartphone) and are self-provisioned from an online catalogue of pre-defined configurations and can scale up or down, automatically. Resource usage is tracked and billed based on service arrangement.

For large corporations, Cloud computing services are a boon. Remote machines owned by another company (Cloud Service Providers) can run everything from E-mail to word processing to complex data analysis programs. These services are extremely efficient and can go a long way in making various function and activities easy and secure. For example, for an executive in a large corporation responsible for managing the purchase of software (and software licenses) and setting it up on the systems of all employees and every now and then on the system of a new hire can be a very stressful task. But with a Cloud Computing service the executive would have to load only one application which would allow workers to log into a Web-based service which would host all the programs and tools the employee would need for his or her job. Thus making adding productivity and efficiency to the overall process.

The Three Cloud Service models

There are three main categories of cloud computing services that form the cloud stack.

Infrastructure as a Service (IaaS): IaaS refers to cloud-based computing infrastructure which is the lowest level of cloud solution, where the vendor provides clients pay-as-you-go access to networking, storage, servers and other computing resources in the cloud.

  • Instead of purchasing hardware users only pay for IaaS on demand.
  • It helps to saves enterprises the costs of buying and maintaining their own hardware.
  • As the data is on the cloud, there won’t be a point of failure in the system.  

Platform as a Service (PaaS): A service provider offers access to a cloud-based environment where developers can build and deliver applications.

  • Provides a platform with tools to develop and host applications and test in the same environment.   
  • Enables organizations to focus on development without having to worry about the underlying infrastructure. 
  • Providers also manage operating systems, security, server software and backups.
  • Helps teams work remotely by facilitative collaboration.

Software as a Service (SaaS): A service provider delivers software’s and applications through the internet. The consumer simply has to access the product through their browser and don’t have to worry about installations or updates. 

  • SaaS vendors provide users software and applications via a subscription model.   
  • Users do not have to manage, upgrade or install software; SaaS providers manage all this.
  • Data is secure in the cloud       
  • Equipment failure does not result in loss of data.  
  • Depending on services resources can be scaled
  • Applications are accessible from any internet-connected device i.e. virtually anywhere in the world.

 

Cloud Computing Benefits

Cloud Computing is playing a vital role in making a large transformation globally to users, developers, enterprise communities in their whole experience of information access, application designing, development and implementation, and administration and management of costs and infrastructure. Cloud Computing helps users to get their applications to market quickly. Cloud hosting provides many benefits to businesses and corporations. It can save money as its cost-effective, increases the efficiency, it’s highly reliable and it provides the agility, flexibility and scalability and high performance.

Given below is an exhaustive list of benefits of Cloud Computing.

  • Lowers IT infrastructure and computer costs.
  • Data Security
  • Prevention of Data Loss
  • Mobility – Flexibility of work practices
  • 24 X 7 Availability
  • Improves performance
  • Less Maintenance issues
  • Instant software updates (Automated Updates on Software)
  • Improved compatibility of Operating systems.
  • Backup and recovery.
  • Performance and Scalability
  • Instantly scalable resources and pay as you go 
  • Strategic competitive advantage
  • Increase storage capacity
  • Get new app run quickly
  • Easily Manageable

The cloud is currently being used by more than 96% of organizations from the world. Organizations of all sizes across industries –manufacturing, retail, media and entertainment, finance and insurance, professional services, software and IT, telecommunications, millennial start-ups – already leverage public cloud services. To understand what makes cloud computing successful, you’ll need to deeply understand the ways in which companies must manage and are managing their IT needs, and develop products and software. As such many IT & Cloud services providers (such as AceTek Solutions) strive to leverage extensive Cloud Computing services to their customers and clients.
