Most of us use Gmail, Dropbox, iCloud and Facebook almost every day. We have become accustomed to the idea of storing our personal data in the cloud. As the world of information and data continues to expand, the cloud is expanding right along with it. The cloud’s presence is well appreciated and accepted in the highly dynamic, information-heavy, always growing corporate arena.
Cloud computing offers a natural competitive advantage to entrepreneurs bold enough to think outside the box. It enables startups and companies to move quickly from an innovative idea to an actual product or service by removing big upfront investments. It allows businesses to scale up or down quickly providing much needed flexibility when responding to changing customer demands. It removes geographic constraints and opens new markets that were previously not accessible. It also enhances external collaboration with partners and customers.
Cloud Deployment Models
Cloud infrastructure is deployed in many ways depending on the requirement of the business. I have listed the major types of deployment models.
Public cloud: A public cloud is the internet. Service providers use the internet to make resources, such as applications (also known as Software-as-a-service) and storage, available to the public.
Private cloud: Private cloud architecture suits an organization or a company that intends to gain the benefits of cloud architecture without giving up the control of maintaining their own data center. Private cloud can be very expensive and not suited for SMEs.
Hybrid cloud: Hybrid cloud is a cloud-computing environment, which uses a mix of on-premises, private cloud and third party, public cloud services with orchestration between the two platforms. Hybrid cloud is particularly valuable for dynamic or highly changeable workloads.
Community cloud: A cloud environment where different organizations belonging to same community share the setup. This is particularly used banks, apartment welfare organizations etc.
Cloud Service Models
Cloud-computing providers offer their ‘services’ according to different models, of which the three standard models per NIST.
Infrastructure as a Service (IaaS): IaaS is a form of cloud computing that provides virtualized computing resources over the Internet. Rather than purchasing or leasing space in an expensive datacenter, labor, real estate, and all of the utilities to maintain and deploy computer servers, cloud networks and storage. AWS, Microsoft Azure Google compute engine are few of the leading IaaS providers.
Platform as a service (PaaS): Cloud model that provides the entire infrastructure required to create & manage custom cloud application. Cloud provider delivers hardware and software tools — usually those needed for application development — to its users as a service. Salesforce.com, Google app engine, AWS Elastic Beanstalk are some of the PaaS vendors.
Software as a Service (SaaS): In SaaS cloud model, service providers host application and make them available for their users over the Internet. SaaS applications are used for emails, CRM, Sales management etc. Intuit, Microsoft, Oracle, SAP are few leading SaaS providers.
Many companies are still worried about the Cloud adoption. The biggest concerns about cloud computing might be Security and Privacy.
Organizations see lot of value in adopting the Cloud. I have listed down few advantages:
- Cloud computing allows companies to avoid up-front infrastructure costs.
- Upgrading the software will be easier: Upgrading software is a daunting task, especially when those updates take place on a massive corporate level.
- Lower operational expenditure: Cloud computing saves the corporate world money on two fronts: IT staffing and equipment costs.
- Scalability on a Corporate Level: Massive, fluctuating amounts of data just comes with the corporate territory, which is another reason why the cloud is so beneficial for major business.
- With cloud computing, increasing and decreasing storage needs is as easy as contacting the cloud service provider.
- It is not easy for small & medium businesses to have access to the experts and finance afforded to larger businesses, but cloud computing now makes this a real possibility.
Thus, Cloud computing has provided a platform to Small and Medium sized enterprises create their niche product and cater it to the customers across the globe and helping large enterprises to cut down on their Opex.
