Moving-To-IaaS

Moving to IaaS: An Overview

Cloud computing, Cloud Migration, Industry insights

According to Gartner’s forecast, infrastructure-as-a-service (IaaS) will be the fastest growing segment of the market with a predicted growth of 27.8%. This shift to IaaS is primarily as a solution for three key use cases.

  1. Moving apps from the corporate data center environment to the cloud.  

The key challenge they are seeking to solve in this desire is to reduce their total cost of updating, maintaining, and operating data centers – this work isn’t core to accomplishing the mission of their business and doesn’t help differentiate them from their competitors. While the corporate data center isn’t going away, its role is changing, and IaaS provides a fantastic route for businesses to run their traditional applications as they resize their data center needs.  

2. Building net new cloud-native applications.  

IaaS provides unique characteristics that just can’t be ignored as businesses look for competitive advantage in building new workloads and delivering next-generation apps for their users. IaaS can provide the ability to scale up and down as user demand changes, can provide fine-grain infrastructure cost control via pay as you go models, and empowers developers to gain control over the servers, storage, and networking that is used to deploy their apps. IaaS is the route of choice for next-generation application development, and businesses today are using it to modernize how they build and deliver apps.  

3. Operating and scaling workloads with special characteristics, like HPC. 

 These types of workloads stress infrastructure in a different way than business productivity apps, and have special performance needs as they generally are spun up, run near max of capacity for a defined time period to generate a specific result, their results stored, and then spun down. 

IaaS: An Overview

Infrastructure as a service is a method where organizations get the hardware, storage, networking and other services they need to run their operations. Instead of buying, managing or maintaining equipment, they rent the equipment, paying only for the capacity and space they use.

The move to IaaS depends on many setups like from full-blown compute as a service to partial infrastructure as a service, such as storage, servers, web hosting and disaster recovery. The amount of infrastructure depends on factors which includes the line of business, the availability of IT staff and expertise and the cash flow constraints.

There are also different ways of implementing IaaS: in a private cloud, public cloud or hybrid private/public cloud. Again, the path an organization chooses depends on several factors and usually comes down to balancing cost with security needs.

Public /Private or Hybrid?

Whether an organization chooses to move its infrastructure to a private or public cloud depends on many variables, namely cost, security and compliance requirements.

Private Cloud:

Every organization would first opt for a private cloud, which is the most secure and at the same time quite expensive. With a private cloud, organizations pay for a computing infrastructure dedicated solely to their core focus. Private clouds can be hosted on the organization’s premises or by an IaaS provider. But in either case, they don’t share resources with other tenants. This is a viable option for enterprises that must cooperate with specific compliance, auditing or governance regulations.

Public Cloud:

On the other end of the spectrum is the public cloud, where infrastructure is hosted in the IaaS provider’s data center and often shared with other customers. But there are caveats: If the organization deals in sensitive information, such as healthcare data or sensitive personal or financial data, a public cloud may not be the right avenue.

However, public cloud requires less spending compared to the other service types. It requires special attention to safety and accessibility and you’ll need to learn a new skill to increase the crossover or to increase the automation to take advantage of the new technology.

Hybrid Cloud:

IaaS Hybrid Cloud is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. The IaaS provider owns and maintains the equipment while the organization rents out the specific services it needs, usually on a pay as you go basis. It’s your own private cloud instance in the public cloud.

Benefits of moving to IaaS

Pay Per Use:

The IaaS service can be used on demand and the users only have to pay for the resources that are actually used.

Saves time and Cost:

The cloud provider is responsible for for setting up and maintaining the underlying hardware required for supporting the IaaS environment. It saves a lot of time and effort of the users and ensures affordability.

Location Independence

Users working on the IaaS environment can access it from anywhere in the world through the internet; however, they have to abide by the security protocol of the cloud network.

Conclusion

Many businesses will benefit from access to on-demand private, public or hybrid cloud infrastructure, although they will need to evaluate the cloud-readiness of their workloads and perhaps make some adjustments to the mix. The IaaS market is evolving rapidly and includes both proprietary and open-source platforms, which makes the choice of technology and service provider a challenge for enterprise IT architects. Given that a hybrid cloud architecture is likely to prove a good fit for many businesses, service providers that make it easy to integrate private and public cloud infrastructure are likely to prosper.
