What Is IaaS (Infrastructure as a Service)?
IaaS is the infrastructure model as a Service, which is serviced. Transactions, storage and network resources are served from a provider. What is IaaS is a critical point of responsibility sharing: the important part of operating system and application management may be in customer while processing by the physical infrastructure provider.
What resources do IaaS provide?
Virtual machines, discs, virtual networks and IP resources are basic components. Load balancer and additional security services can be added according to the products of the provider. The capacity limit of each component, pricing and usage zone are evaluated separately.
For example, virtual machine, storage and network rules can be created for a web application. Application installation, operating system update and user authorizations are also managed. Receiving the source as service does not eliminate the need of technical management.
IaaS, PaaS and SaaS difference
IaaAS offers more control over infrastructure. PaaS manages larger part of the application run platform. SaaS is a ready-to-use application. As the control rises, the customer's management load can also increase; The right model depends on the competence and application requirement of the team.
If an old application needs certain operating system or components, IaAS may be a suitable option. PaaS is evaluated if a new application can work with managed platform. If the ready-made product meets the need, it can create unnecessary operation load to build special infrastructure.
How to check the costs of IaaS?
- Follow trading resources and working hours.
- Measure disc, snapshot and backup capacity separately.
- Check out data output, IP and additional service costs.
- Tag the source owners; Set budget alarms.
- Close unused resources with approved process.
Security and recovery plan
Identity verification is regulated by the lowest authority required by management access and network permissions. The operating system and application are monitored. The physical infrastructure security of the provider does not automatically fix the customer's incorrect access settings.
The frequency of backup is determined by the accepted data loss and return time work units. Pre-testing which resources will be used in the region or provider failure. Application dependency for transport, data export formats and alternative environment plan should be documented. Thus, sustainable operation is also provided.
