The popularity of public cloud adoption has significantly increased since the introduction of the first commercial cloud two decades ago. Many of us now rely on various public cloud-related services in our daily lives, such as social media platforms like Instagram, video streaming services like Netflix, and web-based email applications like Gmail. In the business world, both large corporations and small startups utilize public cloud computing models to achieve flexibility, cost-effectiveness, and scalability necessary for business growth. According to a report by the International Data Corporation (IDC), global spending on public cloud provider services is projected to reach $1.35 trillion by 2027.
A public cloud is a type of cloud computing where a third-party service provider (such as Amazon Web Services, Google Cloud Platform, IBM Cloud, or Microsoft Azure) offers computing resources over the public internet on a pay-per-usage basis. This model allows companies to scale their compute and storage resources automatically to meet their specific needs. In a public cloud environment, the cloud service provider owns and operates large physical data centers that run client workloads in a multi-tenant setting. This setup allows for efficient resource utilization and lower costs compared to on-premises data centers.
Public cloud service providers are responsible for hardware maintenance, high-bandwidth network connectivity, virtualization of servers, and ensuring data security. They also offer various cloud security tools and solutions to prevent data breaches. Service level agreements define the relationship between a cloud service provider and a client, covering the performance, availability, and manageability of cloud services.
Today’s cloud providers offer a wide range of managed services and tools across four main categories. These services include storage, dynamic resource allocation, development and testing, cloud-native applications, DevOps, low code, analytics, hybrid multicloud strategy, generative AI, and edge computing. Businesses can benefit from public cloud solutions by reducing costs, increasing efficiency, scaling resources, fostering innovation, enhancing team collaboration, ensuring high availability and reliability, and promoting sustainability.
In addition to public clouds, other cloud deployment models include private cloud, hybrid cloud, and multicloud. Each model offers unique advantages and can be tailored to meet specific business needs. Businesses can leverage public cloud computing services in various ways to achieve cost savings, drive innovation, and support overall business growth.
