What is cloud computing?

Cloud computing, in simple terms, is a revolutionary computing model that operates through the internet. It encompasses servers, networks, storage, development tools, and applications, all made accessible through the web. Rather than burdening organizations with significant investments in purchasing equipment, training staff, and managing maintenance, cloud computing offers a seamless alternative. It allows businesses to rely on cloud service providers to cater to their computing needs partially or entirely.

Imagine the possibilities when you no longer have to worry about infrastructure headaches or costly hardware upgrades. With cloud computing, you can focus on what truly matters – accelerating your business growth and achieving your goals with ease and efficiency.

Key characteristics of cloud computing

Cloud computing boasts five key characteristics that set it apart as a game-changer in the world of technology:

Characteristics of Cloud Computing

  1. Internet access: With a public cloud environment, you can seamlessly connect to data and applications from anywhere, anytime, thanks to the power of the internet.
  2. Measured service: Cloud computing operates on a pay-as-you-go basis, just like a utility company measures your consumption of water, electricity, or gas. You only pay for what you use, ensuring cost efficiency.
  3. On-demand self-service: Forget about lengthy setups and manual configurations. In the cloud, you can request and access services quickly and easily, without the need for any manual intervention.
  4. Shared resource pooling: Collaboration reaches new heights with cloud computing's multi-tenancy model. Instead of duplicating applications for each user, several users can efficiently share a single application, tailoring it to their specific needs.
  5. Rapid elasticity: Adaptability is key, and cloud platforms excel in this area. You can effortlessly scale your resource usage levels up or down, ensuring your organization meets changing demands with ease.

Deployment models of cloud computing

Cloud computing offers several deployment models to cater to different business needs. Let's explore the four main deployment models: public cloud, private cloud, hybrid cloud, and multi-cloud.

1. Public Cloud

This model involves accessing computing resources hosted on data centers managed by third-party cloud service providers through an internet connection. Organizations opt for the public cloud to avoid the hassle of owning and maintaining on-premise resources. In a shared environment, multiple organizations or tenants leverage the same infrastructure. The industry's leading hyperscalers, including Microsoft (Azure), Amazon (AWS), Alibaba (Alicloud), and Google (Google Cloud), offer massive scaling capabilities, while others like IBM and Oracle also provide cloud services.

2. Private Cloud

Ideal for businesses seeking enhanced control over resources and security, the private cloud model relies on servers owned and maintained by the organization. Accessible via the internet or a private internal network, the private cloud ensures compliance with specific regulatory and compliance requirements, such as HIPAA for healthcare or GDPR for data protection.

3. Hybrid cloud 

Many organizations find a perfect solution in the hybrid cloud approach, which combines various cloud environments. Typically, it includes a mix of public cloud, private cloud, and sometimes on-premise infrastructure. Effective communication or orchestration between these deployments creates a true hybrid cloud architecture. This approach provides flexibility, security compliance, and eliminates reliance on a single cloud provider. Hyperscalers now offer private cloud options in public environments (e.g., VMware on AWS, Azure VMware Services), blurring the lines between "public" and "private" into "dedicated" and "shared."

4. Multi-cloud

In a multi-cloud setup, an organization utilizes services from multiple public cloud providers. This specific case of hybrid cloud empowers businesses to cherry-pick the best offerings from different providers, maximizing their advantages and avoiding vendor lock-in.

Service categories of cloud computing

Let's explore the three service categories of cloud computing, each offering distinct advantages for businesses:

1. Software as a Service (SaaS)

SaaS is a widely used cloud application service that grants organizations easy access to software applications. With SaaS, you access specific applications hosted on remote servers managed by a third-party provider. This subscription-based model allows access through web browsers, eliminating the need for on-device software downloads or updates. Popular SaaS products include Salesforce, Workday, and Microsoft Office 365. Businesses opt for SaaS to quickly enable cloud system access with minimal database management and service provider interaction. It's perfect for web and mobile access applications, short-term projects requiring quick collaboration, and startups launching ecommerce websites without server issues or software development.

2. Platform as a Service (PaaS)

PaaS is a top choice for businesses seeking to create unique applications without significant financial investments. With PaaS, organizations access a pre-defined software development environment, which aids in building, testing, and running applications. Developers benefit from not having to start from scratch, allowing them to focus on the creative side of software development rather than tedious tasks like writing extensive code or managing updates and security patches. Examples of PaaS products include Google App Engine, web servers, and SQL servers.

3. Infrastructure as a Service (IaaS)

For simplicity, IaaS is the ideal option. It involves migrating an organization's hardware to the cloud, renting servers and data storage instead of maintaining its infrastructure. IaaS offers the same technologies and capabilities as a traditional data center, granting full control over server instances. System administrators handle aspects like databases, applications, runtime, and security, while the cloud provider manages servers, hard drives, networking, and storage.

Your cloud migration strategy needs to consider the deployment model and service category.

Leading cloud computing platforms

The cloud computing landscape is led by three prominent platforms: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). These major players collectively dominate over half of the global market share in cloud infrastructure as a service (IaaS), making them the undisputed leaders in the cloud computing race.

  1. Amazon Web Services (AWS): For years, Amazon has been a dominant force in cloud services and continues to expand at an impressive rate. AWS boasts a vast array of over 175 services, covering virtually every major aspect of cloud computing. Notably, AWS offers serverless options, allowing you to run applications, manage cloud storage, integrate applications, and scale automatically without dealing with server management. While AWS is immensely popular, it's important to consider that its complexity and potential pricing confusion might not always make it the best choice.
  2. Microsoft Azure: Azure is Microsoft's robust cloud platform, providing a comprehensive set of cloud services for developers and IT professionals. It enables the building, deployment, and management of ASP.NET Core web applications through a global network of data centers. Azure offers a rich variety of both IaaS and PaaS services, effectively handling dependencies and streamlining cloud deployment processes.
  3. Google Cloud Platform (GCP): Google's cloud platform, GCP, offers a suite of public cloud computing services. It features a set of virtual machines (VMs) running on Google's powerful infrastructure. GCP also provides container services, various cloud storage options, and cutting-edge big data solutions. While GCP excels in advanced services, it may come with a trade-off in terms of user-friendliness.

When choosing a cloud platform, it's essential to evaluate your specific business requirements and objectives. Weighing factors like complexity, pricing, services offered, and user experience will help you make an informed decision to leverage the full potential of cloud computing for your organization.
