Cloud computing allows users access to shared pool of computing resources (computer, network, storage, database, and other services) that can be easily provisioned and released. In simpler terms, it is on demand delivery of computing resources via the Internet.
We can draw an analogy, ‘if you need milk (computing resources), would you buy a cow (software/ hardware)?’
Cloud brings cost optimization, scalability, and agility, which has made it the new standard. There are loads of cloud computing companies offering service today. Amazon Web Services (AWS) is the market leader, and Microsoft Azure is making huge strides in the cloud space.
Thus, it is important for a business to select the right one that comprehends the business infrastructure. So, before making a choice, know all about the Cloud Management Services, Computing Services and deployment models.
# Cloud Computing Services
• Software as a Service (SaaS)
Cloud-centered applications or software as a service (SaaS) run on separate workstations “in the cloud.” These cloud workstations are possessed and operated by someone else, and connect users’ computers over the Internet usually through a web browser.
• Platform as a Service (PaaS)
Platform as a service offers a cloud-based setting including everything that is essential to support the complete lifecycle of developing as well as delivering web-based/cloud applications without the complexity of purchasing and handling the underlying hardware, software, and hosting.
• Infrastructure as a Service (IaaS)
Infrastructure as a service allows organizations to use computing resources such as servers, networking, storage, and data center space on the basis of usage.
# Cloud Computing Deployment Models
• Public Cloud
Owned and operated by firms, the public cloud is useful for individuals or organizations to gain quick access to affordable computing resources. Because of public cloud services, users are not required to specifically purchase hardware, software or supportive infrastructure, as it is all owned and managed by the provider.
• Private Cloud
This type of cloud is held and operated by a single organization. The organization thus controls how several lines of business and leading groups utilize the automated services and virtualized resources. Private clouds take advantage of many of cloud’s competencies while offering better control over resources.
• Hybrid Cloud
A hybrid cloud makes use of the foundation of a private cloud together with the strategic use of public cloud services. It is difficult for private cloud to occur in isolation from the business’s IT resources and the public cloud. Most of the companies that managed private clouds have evolved to even manage workload through data centers, and private & public clouds; thus, creating hybrid clouds.
A prominent factor in cloud service is that these are usually pay-as-you-go. Thus, it is quite easy to try to go to the cloud at relatively low cost and experience the difference. However, with too many service providers, picking the ideal one is an uphill task. So, you have your work cut out, as you need to research and assess which provider offers finest cloud computing service that suits your needs.
