In the modern digital landscape, what is cloud computing? It's a revolutionary technology transforming the way businesses and individuals store, process, and manage data. By allowing users to access servers, storage, databases, and a vast array of applications remotely via the internet, cloud computing enhances efficiency, scalability, flexibility, and cost-effectiveness over traditional IT infrastructures.

The concept of cloud computing isn't new, but its adoption has accelerated with advances in broadband technology, mobile computing, and robust security protocols. Organizations from startups to global corporations are leveraging cloud solutions to innovate, cut costs, and gain a competitive edge. This article will delve deeper into the basics of what is cloud computing, exploring its various service models and discussing the benefits it offers, particularly focusing on how can facilitate your transition to cloud computing.

Understanding what is cloud computing involves different models that define the services offered: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each model provides varying levels of control, flexibility, and management, making cloud computing adaptable to a wide range of business needs. From deploying entire virtual infrastructures to developing complex applications or simply using software over the internet, cloud computing has a solution for every business challenge.

Furthermore, the impact of cloud computing extends beyond business efficiency and operational flexibility. It is a key enabler of innovation in areas such as artificial intelligence, machine learning, and the Internet of Things (IoT). These technologies rely on extensive data processing capabilities and scalable computing power, which cloud computing provides readily and cost-effectively.

In this comprehensive guide, we’ll break down the essentials of what is cloud computing, highlight the different service models, and explain how embracing the cloud can propel organizations into a more productive and innovative future. Whether you’re a business leader, IT professional, or curious learner, understanding cloud computing is crucial in the ever-evolving digital age. Readynez offers specialized training and resources to help you master cloud computing.

Defining Cloud Computing 

At its simplest, what is cloud computing? It's the delivery of computing services over the internet ("the cloud"), including servers, storage, databases, networking, software, analytics, and intelligence. This enables users to access and utilize computing resources without direct active management. Essentially, cloud computing provides a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software.

Key Features:

  • On-demand Self-service:

    Users can provision resources as needed without human interaction from the service provider.
  • Broad Network Access:

    Services are available over the network and accessed through standard mechanisms that promote use by heterogeneous client platforms (e.g., mobile phones, laptops).
  • Resource Pooling:

    The provider’s computing resources are pooled to serve multiple consumers, dynamically assigned according to demand.
  • Rapid Elasticity:

    Capabilities can be elastically provisioned and released to scale rapidly outward and inward commensurate with demand.
  • Measured Service:

    Cloud systems automatically control and optimize resource use by leveraging a metering capability.

Types of Cloud Computing Services 

Cloud computing services are broadly classified into three categories, each serving a distinct need in the IT ecosystem:

Infrastructure as a Service (IaaS)

This is the most basic category of cloud computing services that allows you to rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Platform as a Service (PaaS)

PaaS provides developers with a framework they can use to build upon and create customized applications. Cloud providers deliver a platform, including hardware and software tools, typically those needed for application development. This frees developers from having to install in-house hardware and software to develop or run a new application. Popular PaaS examples include Google App Engine, Microsoft Azure App Services, and Salesforce Heroku.

Software as a Service (SaaS)

SaaS delivers software applications over the internet, on a subscription basis. It is accessible from any device with an internet connection and a web browser. In this model, cloud providers host and manage the software application and underlying infrastructure, and handle maintenance, such as software upgrades and security patching. Examples include Google Workspace, Microsoft 365, and Salesforce CRM.

Benefits of Cloud Computing

Enhanced Collaboration

Cloud applications improve collaboration by allowing dispersed groups of people to meet virtually and easily share information in real time and via shared storage. This can lead to innovations in products and services and improve customer service and satisfaction.

Security and Compliance

Many cloud providers offer a set of policies, technologies, and controls that strengthen security, helping protect data, apps, and the associated infrastructure from potential threats.

Disaster Recovery

Cloud computing can also enhance data security for its users by backing up data off-site, decreasing the potential for data loss due to local disasters.

Each of these benefits underscores the value of cloud computing in today's business environment. offers specialized training to help you and your organization leverage these benefits. By understanding what is cloud computing and how to effectively implement cloud solutions, you can ensure your business remains competitive, agile, and secure.

What's Causing the High Demand for Cloud Professionals:

Several factors contribute to the high demand for cloud professionals. The exponential growth of data and the need for scalable infrastructure solutions drive organizations to adopt cloud technologies. Additionally, the COVID-19 pandemic accelerated the shift to remote work, further fueling the demand for cloud-based collaboration and productivity tools. Moreover, the cost-saving benefits, agility, and innovation potential offered by the cloud continue to incentivize businesses to invest in cloud solutions, creating a sustained demand for skilled cloud professionals.

Average Salaries of Cloud Professionals:

Cloud professionals command lucrative salaries, reflecting the high demand for their expertise. According to recent surveys, the average annual salary for cloud architects ranges from €100,000 to €130,000, while cloud engineers can expect salaries in the range of €85,000 to €120,000. Cloud developers and cloud security specialists also enjoy competitive compensation, with average salaries ranging from €75,000 to €110,000.

Obtaining relevant certifications is crucial for aspiring cloud professionals to validate their skills and enhance their marketability. Let's delve into each certification to understand its significance and the skills it validates:
