Infraestrutura como Serviço (IaaS) is a computação em nuvem model that delivers fundamental computing resources such as virtual machines, storage, and networks over the internet. IaaS is one of the three main categories of cloud services, the others being Platform as a Service (PaaS) and Software as a Service (SaaS).
In an IaaS model, users can access and manage computing resources without the need to invest in physical hardware. This allows businesses to scale their infrastructure up or down based on demand, providing flexibility and cost-effectiveness. IaaS providers typically offer services on a pay-as-you-go basis, meaning users only pay for the resources they consume.
As soluções de IaaS incluem uma variedade de serviços, como:
- Máquinas Virtuais: Users can create and manage virtual servers with different configurations according to their needs.
- Armazenamento: Options for scalable storage solutions, including block storage and object storage, are typically available.
- Redes: Users can set up virtual networks, load balancers, and IP addresses to manage their infrastructure effectively.
Exemplos comuns de provedores de IaaS incluem Amazon Serviços Web (AWS), Microsoft Azure, and Google Cloud Platform (GCP). These platforms enable organizations to deploy applications, host websites, and run workloads without the complexities associated with maintaining physical servers.
No geral, a IaaS simplifica a TI management, reduces capital expenditures, and allows businesses to focus on their core activities rather than infrastructure maintenance.
