A Beginner’s Guide to Cloud Computing
- 1. A Beginner’s Guide to Cloud Computing - Global Knowledge Technologies
- 2. Remember the days when we used to store data in floppy disks? The present day is different-with the advent of cloud, storage and access of data is no more an arduous task. Whether it is big corporations or individuals, everyone is leveraging the power of Cloud. The impact of Cloud Computing is so high that, Forbes in its Cloud Computing Forecasts projected it will witness an increase to $162B in 2020 from $67B in 2015attaining a compound annual growth rate (CAGR) of 19%.

- 4. What is Cloud Computing? It was not very long ago when people had to maintain a pile of physical documents which if lost or misplaced could cost a great deal. Cloud Computing has transformed how the internet was used completely-enabling storing data in a centralized location which can be accessed from computer and mobile device anytime anywhere. Whether it is pictures, important data, now with the access of cloud, sharing files has never been so easy. To sum up, Cloud literally acts as a virtual drive or maybe more than that.
- 5. Cloud Computing Service Models • Cloud services are based and categorized on three service models, namely- Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). • IaaS in cloud computing: The first layer of Cloud, IaaS or Infrastructure as a Service involves delivering cloud computing infrastructure where third party providers such as Amazon Web Services, Microsoft Azure or Google, hosts virtualized computing resources over the Internet. • PaaS in cloud computing: Platform as a service (PaaS)- the second cloud layer is a cloud computing model that enables delivering applications over the internet where a developer can easily create, run, test and manage the applications over cloud. • SaaS in cloud computing: SaaS or Software as a service is the third layer, which is also popularly known as ‘on-demand software’, it is a software distribution model where applications can be hosted centrally on the cloud server and can be accessed directly without downloading or installing.
- 6. Deployment Models in Cloud Computing • Private Cloud: Provides its services exclusively to a single enterprise or institution. In Private Cloud model the cloud infrastructure can be tracked only by the cloud provider or the user. • Public Cloud: In the Public Cloud model, the services and infrastructure remain open to use for the general public. While the users have no control over the location of the infrastructure, they can access the services over a public network such as the internet. • Hybrid Cloud: This Cloud model is basically the amalgamation of both Public Cloud and Private Cloud infrastructure where the particular enterprise or institution using it can benefit in the aspect of attaining scalability, flexibility, and security.
- 7. Top Cloud Providers • The popularity of Cloud is not only among businesses but also general users that stimulated number of companies to provide cloud services in the recent years. Today there are numerous cloud providers; however, there are handful of them who are leading in the cloud market. • Google Cloud Platform • IBM Cloud Services: • Amazon Web Services: • Microsoft Azure:
- 8. Why take Cloud Computing Certification? • Indeed’s search revealed that there are around 25,000 unfilled positions in the U.S. that are relevant to AWS alone. • According to the predictions by International Data Corporation IDC that the spending on public cloud services and infrastructure is projected to exceed $277 billion by 2021 in an annual growth rate (CAGR) of 21.9 percent. • There is a rise of 33% in employers expressing interest in cloud computing skills. • By 2022, the overall development in IT spending on cloud-based offerings will be faster compared to the traditional (non-cloud) IT offerings- that will make cloud computing count as one of the most disruptive forces in the IT landscape. • For Cloud Engineers in India, the average salary as of 2019 is INR 12, 01,527 according to Glassdoor.
