Cloud services are becoming the number one choice for a lot of companies for their hosting needs for any given IT project. But how to choose the suitable cloud hosting service for your project? The first step would to better understand what each solution has to proposed. The following article will help you selecting the best cloud hosting model for your business.
IaaS, PaaS & SaaS
When considering cloud hosting, you have to understand the differences between IaaS, PaaS and SaaS which are the three main cloud services categories:
- Infrastructure as a Service (IaaS): Refers to a cloud service where the user can provision and use components like processing, storage or networking resources.
- Platform as a Service (PaaS): Refers to a cloud service where the user can deploy, manage and run applications using one or multiple programming languages and one or more execution environments supported by the cloud service provider.
- Software as a Service (SaaS): Refers to a cloud service where the user can use the cloud service provider’s applications.
With IaaS, you gain access to the computing and storage resources, operating system, web server, application server, database server and other configurations. The level of access provides pretty much all the control you could possibly need. This is a great model for those who has sys admins in their IT department or developers with server configuration skills.
PaaS is a developper oriented model and an extension of IaaS. PaaS removes server configuration from cloud hosting that allows developers to concentrate on what they do best, coding so all configuration and update management is done by the provider. The inconvenient with that model is the limited level of control, software and development language options. You will have to consider the fact that your applications will run on a specific platforms and make sure that your developers are familiar with that platform and the developing language used. This is a great model for those who develops applications but doesn’t have the skills to take care of configuring and installing server apps.
For SaaS, this service is used to provision an application ready to be deployed over the internet. It offers a product with features, functions and benefits designed for a specific market.
Cloud vs Dedicated
Some people may wondering if cloud is the way to go or should stick with dedicated hosting. The key attribute that differentiates cloud hosting and dedicated hosting is how the resources are allocated and provided to the customer.
For dedicated hosting, physical servers are configured and deployed one at a time and owned by the customer, who will pay a fixed monthly price until they decide to upgrade, close or migrate servers.
With cloud hosting, physical resources are shared between customers and managed by the cloud service provider. The customer can deploy Virtual Machines (VM) that use an allocation of the resources in the pool. The VM computing resources are easily configurable which means that the customer can scale up or down instantly and you can also deploy multiple VM in less then a minute. Dedicated servers requires more time if you want to upgrade capacity since you will have to contact your dedicated server provider and ask for a hardware replacement. Cloud hosting also offers also the ability to purchase on a pay-per-use basis: by the hour, for the amount of resources you use that hour.
You may wondering what is the best solution for your hosting needs, as an example, a website that sees consistent traffic levels does not need to scale up and down so a cloud hosting solution may not be required. As another example, a large and busy database may achieve more consistent read and write speeds on a dedicated server.
Public & Private cloud solution
Public cloud: Public Cloud could be defined as a cloud IaaS managed by a cloud service provider and available to almost anyone, usually with the features described above (IaaA).
Private cloud: It offers the same features as the public cloud, except that the pool of computing and storage resources is controlled and exclusively available to a customer. This infrastructure may be hosted by the customer (on-premises), or hosted by a hosting provider (off-premises). With private cloud, the customer pays a fixed price for the infrastructure plus any software licensing. For customers who value the flexible and responsive features of cloud hosting and the fixed-cost model of dedicated hosting, this is an interesting choice.
