Infrastructure as a Service (IaaS) in Cloud Computing

Preface – This post is part of the Cloud Computing series.


Infrastructure as a service is the service model of cloud computing. IaaS provides services such as storage, networking, memory, compute on-demand. It offers a virtual infrastructure of services that users can run on any operating system or applications on rented servers without the maintenance and upfront cost.

In 2012, IaaS was introduced by oracle as a cloud computing service model. IaaS offers a guaranteed service-level agreement (SLA) regarding uptime and performance. The IaaS cloud computing platform cannot replace the traditional hosting method, but it provides more than that, and each resource used is predictable per usage.

Issues to be considered while choosing IaaS

  • Security
    The ideal service model should be capable of managing security threats. The malware must also be considered because the infection results can range from mild to terrific, and all your data can get erased. Servers can also be affected by damage or unauthorized access; when that happens, it usually isn’t a pretty sight.
  • Service
    The necessary information, such as service level agreement (SLA) should be provided before using the service, and other essentials, such as technologies, scalability, and performance, should be functioning correctly.
  • Multitenant architecture
    As IaaS providers tend to allocate infrastructure resources to multiple clients as needed, the provider must ensure that customers who cannot access each other’s data are logically separated.
  • Flexibility
    The service should be able to respond to changes and bring changes to customers. We can purchase the needed resources and add or delete them to meet changing demands.


Top companies offering Infrastructure as a service

  • CenturyLink Cloud
    Provision, process, and store network resources with on-demand, self-service, FedRamp certified access for maximized control and scalability. The IaaS is located in two geographically redundant locations. The locations are designed with high availability of load balancers, dynamic resource schedulers, and other VM protections to move workloads within the cluster and ensure availability for rapid application delivery to users.
  • CloudSigma
    CloudSigma offers open networking, No restrictions on operating systems and software, Transparent billing and pricing based on actual usage, and other flexible and hybrid services on the IaaS and PaaS principles.
  • OpenStack
    OpenStack is a cloud computing platform that primarily uses IaaS and offers virtual resources for computing, networking, storage, and image services. It provides an entirely scalable solution to fit every cloud hosting need.
  • IBM Cloud
    The IaaS services of the IBM cloud are highly optimized for better performance. In IBM, end users can manage and deploy servers on multiple platforms without any conflicts with secure, next-generation, and hybrid cloud solutions. It is the most secure platform with over 170 products and services covering data, blockchain, and data analytics.
  • VMware
    VMware products include self-service, automation, encapsulation, High availability cluster to quickly handle hardware failure, Storage DRS that stores data without experiencing latency, etc.
