Introduction to cloud computing services
Cloud Computing Services – It’s computing as a service over the internet.
These days a real buzzword is the cloud computing services – but what exactly is the cloud, how does it impact you and your work?
The cloud is computing based on elastic shared resources delivered to endusers in a self-service, metered manner using internet and web technologies. It is a model for delivering IT services in which resources are retrieved from the network using internet through web-based applications and tools, rather than a direct connection to a server – empowering the user to work remotely from anywhere and on any device.
What is cloud computing?
Cloud computing is the next stage in the Internet’s evolution. It is bringing everything from computing power to computing infrastructure, apps, business processes to strategic collaboration together that can be delivered to you as a service.
These services are available on demand and are delivered economically without compromising security or functionality. It enables people the access to these services on any device, any time and from anywhere in the world.
It’s no secret – the cloud powers business innovation. Cloud computing is transforming competitive landscapes by providing new ways to create and deliver value. Cloud enables you to amplify innovation, increase agility, capitalize on analytics, and get personal.
To take full advantage of cloud computing, organizations need to evolve it’s IT strategy to achieve greater business value through the improved productivity and cost-savings that cloud services offer.
Why you should opt for cloud computing services?
You should consider cloud computing if you answer is Yes for any on the following:
Types of cloud computing services and solutions
Private cloud (also known as internal cloud or corporate cloud) is cloud infrastructure dedicated to a particular organization. This cloud is not shared with any other organization, whether managed in-house or by a third-party, and it can be hosted in-house or externally.
A private cloud exists within the company environment (firewall) and its access is restricted, usually to company staff or business partners or associates.
A private cloud is designed to offer same quality, features and benefits of public cloud, but removes a number of objections to the cloud computing model including control over enterprise and customer data, worries about security, and issues connected to regulatory compliance.
Private cloud provides more control over the company’s data, and it ensures better security as compared to Public cloud, although with a greater potential risk for data loss due to natural disaster since it is implemented behind corporate firewall.
The organization implementing the private cloud is responsible for running and managing IT resources instead of passing that responsibility on to a third-party cloud provider. This calls for capital investments and complex technology expertise.
Move to Private Cloud if:
Public clouds are made available to the general public by a cloud computing service provider who hosts the cloud infrastructure. Generally, public cloud providers like Microsoft, Cisco and Salesfore, Amazon AWS, IBM etc own and operate the infrastructure and offer access over the Internet.
In this model, the customers have no visibility or control over the location of infrastructure. All customers on public clouds share the same infrastructure pool with limited security, configuration, protections and availability.
Public Cloud customers benefit from economies of scale, since the infrastructure cost is spread across the users, allowing each and every client to operate on a low-cost, “pay-as-you-go” model. Public cloud is also provides clients with on-demand and seamless scalability. Public Cloud offer the greatest level of efficiency in shared resources; but at the same time they are more vulnerable than private clouds.
You should choose a public cloud when:
A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and some other resources are provided and managed by third party.
Ideally, the hybrid approach allows a business to take advantage of the scalability and cost-effectiveness that a public cloud computing environment offers without exposing mission-critical applications and data to third-party vulnerabilities. This type of hybrid cloud is also known as “hybrid IT”.
For example an enterprise could implement hybrid cloud hosting to host their e-commerce website within a private cloud, where it is scalable and secure, but their catalogue site in a public cloud, where it is more cost effective (and security is less of a concern).
The Hybrid Cloud allows customers to save IT resources and money by moving less critical applications and data to the Public Cloud, while maintaining sensitive data and applications in a Private Cloud.
Companies should opt Hybrid Cloud when:
Software as a service (SaaS)
Cloud-based applications — or software as a service (SaaS) — run on distant servers on the cloud that are owned and operated by third party ISVs or ASPs and that connect to users’ computers via the Internet and, usually, a web browser. Here software and associated data are centrally hosted on the cloud and are delivered as service. This is sometimes referred to as “on-demand software”.
For example, Gmail is a cloud-based SaaS application that replaces traditional email programs that run on your computer, like Thunderbird or Outlook.

Platform as a service (PaaS)
PaaS provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) application. You can make it widely available to users through the Internet. PaaS offers cloud-based application development tools, with services for testing, collaborating on, deploying, hosting, and maintaining apps.
You can also use PaaS to create multi-tenant application which is accessed by many users concurrently. The open design of PaaS can support integration with legacy applications and interoperability with on-site systems. Interoperability gives you the flexibility to take advantage of cloud benefits while retaining data and applications on site as needed.

Infrastructure as a service (IaaS)
Infrastructure as a Service (IaaS) sometimes referred to as Hardware as a Service (HaaS) provides companies with computing resources including servers, data center space, storage, and networking. Cloud-based infrastructure is swiftly secure, scalable and accessible over the Internet — you only pay for what you use.
Businesses can reduce IT capital investments, while gaining true agility—the ability to adopt new capabilities quickly—as well as the ability to use IT to drive fundamental business innovation.

Data as a service (DaaS)
Today data floods into enterprise systems from myriad channels — corporate systems, mobile devices, social media, sensors etc. Managing that ever-changing enormous flow of data isn’t simple. To maximize the value of data to enterprise business operations, it must be separated from the underlying tangle of management, compliance, and integration problems that often stunt enterprise ability to use data for competitive advantage.
Data as a Service (DaaS) is an information provision and distribution model where data files are made available to clients over the network. DaaS offers easy and cost-effective solutions for client-oriented businesses and customers. It is emerging as underlying technologies that support SOA (service-oriented architecture) and Web services mature.
The evolution of SOA has significantly reduced the relevance of the particular platform on which data resides. DaaS began with the notion that data quality is possible only in a centralized location, enriching and cleansing data and offering it to different devices or systems, software applications or clients, irrespective of where they were on the network. With DaaS, any business process can access data wherever it resides.
DaaS empowers businesses to use data as a independent standalone asset and connect with partner data to make informed and smarter decisions. DaaS is a service in cloud that offers variety, scalability, connectivity, including support for cross channel, cross device, and known and anonymous data.
Cloud computing services #Benefits of DaaS include the following:
