PACI offers more flexibility than a virtual private server, making it more cost-effective: SMB customers can grow or shrink their resources — CPUs, memory, and storage — dynamically as their needs change, and only pay for what they use. What if they need a thousand servers for just 1 hour? With PACI, they can do exactly that.
Another difference is programmability. Customers don’t need programming skills to use PACI — but if they are developers, the exposed APIs enable them to apply their own business logic to the service. In addition, PACI makes load balancing available to SMB customers as an option, enabling them to add it with a click when they want it, and giving Service Providers another value-added service for their customers. Other key advantages of PACI include an intuitive user interface that makes it easy for customers to manage multiple servers from a single control point; a virtual private network that’s delivered by default; and a single firewall that applies to all servers; these advantages are summarized in the chart below.
|Scalability||Must buy enough capacity to support peak usage.||Can dynamically scale up and down as load changes.|
|Pricing||Fixed charge per VPS.||Variable, based on usage.|
|API accessibility||No API access; managed via control panel.||Exposed APIs allow custom programmatic management.|
|Availability||Load balancing not available through software.||Load balancing is easily initiated as needed.|
|Ease of use||Difficult to manage multiple VPSs together; have to manage each one individually.||Intuitive user interface makes it easy to manage multiple servers.|
|Security||Software-based vLAN not available; fire-wall available only on a per-VPS basis. Lack of policy consistency across VPSs makes firewall management difficult and prevents free-flowing communication between VPSs (communication requires complex mapping).||Software-based vLAN is delivered by default; one firewall applies to all instances.|
|Storage||Local storage.||Local storage with future network storage options.|
