Which Cloud is Right for My Business?
Cloud computing is quickly becoming a necessary tool in business as more and more companies utilize it to increase efficiency and effectiveness. In fact, leading data analysts expect IT expenditures on Cloud computing to grow by 21% in 2015 and account for approximately 33% of all IT infrastructure spending.
There are numerous benefits to Cloud computing, including virtualized resources, scalability, flexibility, and turning expensive capital expenditures into operating costs. Though deciding to implement a Cloud strategy may be an easy decision, choosing between a public, private, or hybrid Cloud may not. So what are the primary benefits of each choice?
Public cloud is a multi-tenant environment where the computing resources are pooled and shared. Public cloud provides increased flexibility and scalability. As opposed to paying for the computing resources needed to meet your peak demands throughout the entire year, public cloud gives customers the ability to scale up or down depending on your needs. This is especially useful for eCommerce sites that may experience dramatic shifts in website traffic depending on the time of year.
Though some critics argue that public clouds are not sufficiently secure, Forbes recently pointed out that public clouds are often more secure than most companies’ internal data centers and security measures. One drawback to public cloud is the ‘noisy neighbor’ effect where one tenant monopolizes the cloud resources and negatively affects the performance of the other tenants.
In a private cloud environment, computing resources are dedicated to a single organization as opposed to the multi-tenant public cloud. Since resources are dedicated to one company, the private cloud model offers more control. The virtual environment can be customized to achieve a high level security, making it the ideal choice for organizations bound by compliance regulations such as PCI and HIPAA. The dedicated nature of private cloud also means the resources are always guaranteed, eliminating the noisy neighbor effect and assuring high-performance and availability for mission-critical applications.
Hybrid Clouds allow you to mix and match public, private and physical servers. You can create an IT infrastructure environment that meets your needs exactly and ensures the highest return on investment. The hybrid Cloud allows you to utilize both multi and single tenant Cloud environments, giving you the flexibility and scalability of a public Cloud with the compliance and security benefits of a private Cloud.
Hybrid options also include colocation and cloud computing combined as a service. With this solution, you’ll be able to safely and securely maintain and house servers and systems you’ve previously invested in while saving on future capital expenditures by running some applications through the Cloud.
When choosing between a public, private and hybrid Cloud, it’s best to start by understanding your own needs and what each option offers you. In order to fully evaluate this, first determine what level of security, flexibility, scalability and customization your business will need. From there you should be able to narrow to a single Cloud computing option.
