IaaS hosts infrastructure on the public cloud and private cloud instead of in an on-premises data center. The infrastructure delivered to customers on demand while being fully managed by the service provider. It is a cloud computing service where enterprises rent or lease servers for compute and storage in the cloud and use this as platform as a service.
It is a scalable alternative to a traditional datacenter that allows businesses to avoid the cost of provisioning and maintaining their own physical IT infrastructure.
Benefits of Infrastructure as a Service (IaaS):
- Continuity and disaster recovery: Cloud service in different locations allows access to applications and data during a disaster or outage.
- Faster scaling: Quickly scale up and down resources according to application demand in all categories of cloud computing.
- Core focus: IaaS allows enterprises to focus more on core business activities instead of IT infrastructure and computing resource
- Reduce Costs and Up-front IT infrastructure Investment with IaaS
Implementation of Infrastructure as a Service:
It can be implemented in public, private or hybrid cloud setting. It is accessible through an API key so new servers are brought online as part of an automation when needed.
Enterprises use IaaS to do the following more efficiently:
- Test and development: With IaaS, it is easy and fast to setup test and development. Which helps to bring applications quicker to market.
- Data Recovery: IaaS solves storage and recovery issues.
- Big Data Analysis: IaaS provides the processing power to economically large data sets.
Infrastructure as a Service Examples:
Infrastructure as a service example includes the below features.
- Network: Users can build and manage multiple virtual networks through application programming interfaces (APIs). IaaS providers also deliver several networking services and tools for configuring and managing virtual networks
- Storage: Infrastructure as a service combines data storage from multiple disks and machines to appear as a single virtual storage entity. it uses the object storage method.
- Compute: Virtualized compute resources in an IaaS environment are also referred to as virtual machines (VMs). End-users can configure virtual machines to spec allocating processing power and memory as needed.
- Physical Data Centers: IaaS providers manage the data centers, the resources are abstracted and distributed to users who then access them through virtualization. Many businesses are moving toward Infrastructure as a Service as a supplement or replacement to their on-site data centers.
Infrastructure as a Service Providers:
Since we already discussed about the importance of the IaaS in current technical scenario, there are several providers which offer these and Protected Harbor excels at this with a wide customer base and providing the services to them with 99.9% uptime along with round the clock support. Few more examples of IaaS providers are AWS (EC2 instances, S3 Storage), Microsoft Azure, Google Cloud Platform (Google Compute Engine, Google Cloud Storage) etc.
