IaaS, i.e., Infrastructure as a Service, also known as Hardware as a Service. Organizations usually give their IT infrastructures such as servers, processing, storage, virtual machines, and other resources in this model type. Customers can access the resources very quickly on the internet using the on-demand pay model.
Take up IaaS for cloud computing course and understand more about these clouds and their specifications.
The Iaas platform eliminates the need for every organization to maintain its IT infrastructure.
IaaS is divided into three aspects: public, private, and hybrid. The private cloud can offer that infrastructure that resides at the customer end. In contrast, the public cloud is located at the cloud computing data Centre end, and the hybrid cloud is a combination of both public and private clouds.
IaaS provides us with various services, which are listed below:
Compute: Computing various services, including virtual CPUs, Virtual main memory for virtual machines at the user end.
Storage: IaaS provider provides back-end support for storage for storing files.
Network: Network as a Service provides networking components such as routers, switches, and bridges for virtual machines.
Load Balancers: It gives load balancing at the infrastructure layer.
Advantages of IaaS in Cloud Computing:
Shared Infrastructure
- IaaS gives shared users to share the same physical infrastructure.
Web Access to the resources
- IaaS allows IT users to access resources over the internet.
On-demand as per usage model
- Iaas providers provide services only as a clients pay-as-you-go model.
Business model focus
- Iaas Providers give business core organization focus rather than IT infra.
Update versions of the Software
- There is the scalability of services provided as there is no problem with software upgrades and troubleshooting issues related to IT infrastructure.
Disadvantages of IaaS in Cloud Computing
Security
- Security is the main concern in IaaS as it is not 100percent sure.
- Maintenance and up gradation
- Although IaaS providers maintain the software but not for all.
Interoperability issues
- It is difficult to migrate Virtual Machine form one IaaS provider to another, so customers experience problem related to vendor lock.
- Main Iaas Cloud Service providers are Amazon Web Services, Microsoft Azure, and Google Cloud Platform etc.
