Infrastructure-as-a-Service (IaaS), has enabled organizations to rent IT infrastructure from a service provider rather than purchasing the technology and hosting it internally. IaaS cloud has moved ahead of the general cost-benefit upsides and has allowed organizations to develop and host highly voluminous consumer-facing and B2B content.

Implementing IaaS cloud can be a challenging task. Many organizations face scalability, pricing and performance issues. In some instances, IaaS providers are still trying to develop and improve their practices to meet customer demands. If you want to have a successful cloud experience, you must dig a little deeper into how IaaS services work and keep a realistic approach. In our previous blog post, we stated how to choose between private cloud and virtualization automation. In this post, we present to you the five questions you must ask before adopting an IaaS cloud strategy.

  1. Does the application sit on x86 architecture? You must check whether your application is compatible with the compute-intensive x86 cloud infrastructure. x86 cloud architecture provides a high level of data integrity and improves data security by using an advanced encrypting algorithm. Also, it ensures tight integration with internet backbone infrastructure, thus supporting industry-standard software and tools used to architect IaaS cloud. Hence, your application's compatibility with x86 architecture is required.
  2. Can the application sit on a virtualization hypervisor? Cloud computing lets you access a virtual machine and complete your tasks from anywhere. A hypervisor manages these virtual machines. It is a program that allows you to host several different virtual machines on a single hardware. Each of these virtual machines is able to run its own program. It gives you the illusion that system has the host hardware's processor, memory, and resources. But, in reality, the hypervisor allocates resources to this virtual machine. A virtualization hypervisor is an essential component of IaaS cloud. Hence, your application must be compatible with it.
  3. Does the application have any high capacity performance requirements? In an IaaS Cloud, the instances of virtual machine share the physical machines in provider's data center. If your application has a high capacity performance requirement, it might need a number of physical machines connected to the cloud. An increase in the number of physical machines leads to rise in infrastructure and operational costs. Hence, you must determine your application's capacity requirement and develop a scalable model for the performance, availability and power consumption of an IaaS Cloud.
  4. Are all the privacy compliances fulfilled by the public cloud? You must compare the privacy policies provided by a public cloud and private cloud. Also, you must thoroughly understand the privacy risks involved in the public and private cloud. Based on this information, you can take a decision whether you want to implement IaaS cloud or server colocation.
  5. Does the application have a fixed lifespan? Using an application lifecycle management program, you can determine the exact lifespan of your application. Based on this information, you can further decide whether your application requires IaaS cloud or collocation.

Today many IT professionals and company owners are realizing the benefits of not locking into a single vendor and instead, choosing tools.
