Cloud computing has gained major industry-wise traction in recent years, though not new to the IT world. Since its conception, cloud computing has changed the way organisations look at application infrastructure and services. As a result, cloud technology has become a crucial part of the digital era, and an individual who has taken cloud computing courses is set to have an advantage.
The generic term for offering hosted services over the internet is cloud computing. In cloud computing, everything is stored on the cloud. That means there is no capital expenditure, and operational costs are strictly limited to your usage. As a result, firms do away with the complexity of owning an infrastructure with cloud computing. Moreover, cloud computing is more secure, fault-tolerant, highly available, and offers virtually infinite scalability.
CLOUD COMPUTING HISTORY
In the 1960s, computer bureaus allowed organisations to rent the devices instead of buying one independently. This was known as time-sharing.
With the advent of PC and data centres, the concept has now evolved to cloud computing, taking advantage of the emerging data need and the incoming public platform-as-a-service and infrastructure-as-a-service giants like AWS cloud and Azure cloud.
In addition, the hyper-popularity of cloud computing has resulted in a skyrocketing amount of available cloud computing courses.
SERVICES AVAILABLE IN CLOUD COMPUTING
The services range from storage, computing, networking, analytics, machine learning, natural language processing, artificial intelligence, and standard office applications. Most of these services and tools are scalable and highly available.
CLOUD COMPUTING MODELS
Cloud computing models can be broken down into 3 types
- Infrastructure as a service (IaaS)
The fundamental blocks of computing can be rented – physical and virtual servers, networking, and storage. Companies that want to build from scratch and be involved in the basics find this service attractive. According to a survey conducted by Oracle, most of the users stated that IaaS allowed for more innovation and reduced their deployment and maintenance costs.
- Platform as a service (PaaS)
This is one step ahead. It provides underlying storage, virtual servers, and networking. In addition, it includes tools and software like middleware, operating systems, database management, and development tools.
- Software as a service (SaaS)
This is the delivery of applications. The most used cloud computing service, the underlying software, and OS are irrelevant to the consumer. He will access the service via a browser or an app. This service is bought on a per-seat or per-use basis.
TYPES OF CLOUD COMPUTING
There are three cloud computing variants:
- Public Cloud:
The cloud is owned by a third-party provider and operated by them. They deliver their cloud computing services over the internet. The hardware, software, and support systems are owned and managed by the cloud provider. An example of a public cloud is the Microsoft Azure cloud.
- Private Cloud:
This is owned and used for a single business entity. It is mostly located on the organisation’s onsite data centre.
- Hybrid Cloud:
Hybrid cloud takes the best features from both public and private clouds. In addition, hybrid clouds allow for much-needed flexibility in business by allowing sharing of data and applications in-between the private and public cloud.
BENEFITS OF CLOUD COMPUTING
- Cost: The capital expense in setting up the infra like hardware, software, and running the data centres is avoided.
- Speed: Cloud computing services can provide substantial computing resources within minutes. It is all just a click away. So the pressure of capacity planning isn’t there.
- Global Scale: The option to scale up or down to high levels is allowed easily. The motto is to deliver the apt services at the right time.
- Productivity: Data centres require racks and stacking, and other time-consuming IT tasks. Cloud computing does away with most of the tasks, allowing the team to concentrate more on the job.
- Reliability: Data backup, recovery, and business continuity is easier and reliable with cloud computing
- Security: The cloud providers offer policies, technologies that strengthen security and provide overall safety to your data, infra, and apps.
CLOUD COMPUTING COURSES
Given the impact that cloud computing has on businesses worldwide, the need for individuals with cloud certification is high. An individual can be a certified cloud computing professional by undergoing any of the Microsoft cloud courses available and passing the certification exams.

With the growing demand, cloud computing courses are also increased. You can access cloud courses in free and instructor-led, paid variants today. As a result, firms do away with the complexity of owning an infrastructure with cloud computing. Moreover, cloud computing is more secure, fault-tolerant, highly available, and offers virtually infinite scalability.
