Cloud computing has transformed the way businesses and individuals access IT resources. Instead of purchasing and maintaining physical servers, you can rent computing capacity, storage, and software over the internet. The main service prototypes are IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). Scalability is one of its greatest benefits, allowing resources to be quickly adjusted according to demand. However, security remains a central concern, requiring constant attention to data protection and compliance.
The Offering Matrix - Public, Private, and Hybrid Cloud
The cloud computing landscape is more complicated than just "the cloud." There are different deployment prototypes that meet specific needs. The public cloud, offered by major providers such as AWS, Azure, and GCP, is characterized by shared resources and massive scalability. The private cloud offers dedicated infrastructure for a single organization, providing greater control and security, but generally at higher costs. Hybrid cloud, on the other hand, combines elements of both, allowing companies to move workloads between environments as needed, optimizing costs and flexibility. Choosing the most appropriate cloud prototype depends on factors such as security requirements, regulatory compliance, budget, and performance needs. Additionally, multicloud, the use of services from different public cloud providers, is also gaining popularity to avoid vendor lock-in and take advantage of the best offerings from each.
