Businesses invest a great deal of money into dedicated servers. What may start with one server and a few gigabytes of data can eventually grow into an entire server cluster with several petabytes of data. Ideally, a hosting or colocation provider will give businesses the tools to smoothly transition from one stage of development to the next. This is scalability, and every business needs it.
Scalable hosting includes both the hardware and the software platform. Both should allow for seamless upgrades and data expansion. Additionally, the network infrastructure will also need to be scalable in order to handle an increased flow of traffic. Power management and cooling should also be flexible enough to handle the escalated load without overheating or causing an outage.
Scalable hardware may include CPU expansion, RAM expansion, the ability to add additional racks, mass storage add-on capabilities, rapid deployment, and load balancing of power and system resources.
Scalable software may include OS support for multi-core processors and hyperthreading, hardware virtualization support (Intel VT-x and AMD-V), cluster file system support, database scaling, load balancing software, and caching proxies.
Ideally, businesses grow over time, and that means hosting technology should grow with it. A good hosting provider or server vendor will afford you with scalable technology at a reasonable price.
