IaaSpohjaiset

IaaSpohjaiset is a Finnish term used to describe IT architectures and services that are based on Infrastructure as a Service (IaaS). In practice, IaaSpohjaiset deployments rely on virtualized compute, storage and networking resources provided by an external cloud provider, while the customer retains control over operating systems, middleware, and applications. The term is often used in Finnish IT discussions to distinguish IaaS-based setups from Platform as a Service (PaaS) or Software as a Service (SaaS).

Key characteristics include the use of virtual machines and managed storage and networking from an IaaS provider, with management responsibility for guest operating systems, runtimes and applications staying with the user. IaaSpohjaiset environments are commonly provisioned and managed through infrastructure-as-code tools, enabling automation, replication and scalable deployments. They can be deployed in public, private or hybrid cloud configurations.

Benefits include greater control over the software stack, portability of workloads, and elastic scaling with usage-based pricing. They are well-suited for custom or legacy applications, regulated workloads requiring specific configurations, or scenarios needing fine-grained performance tuning.

Challenges include shared security and compliance responsibilities with the provider, potential complexity of governance, data sovereignty concerns, and performance variability. Adoption often requires mature IT processes and tooling, such as configuration management and monitoring.

Origins: the term reflects Finnish cloud discourse and is used to categorize IaaS-based deployments. See also cloud computing, IaaS, PaaS, SaaS, hybrid cloud.
