Benefits Of Using Rack-Mounted Servers When Running A Cloud Computing Service
A cloud computing service can be divided into two main categories: Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS). IaaS is the more common of the two services. With an IaaS model you host your virtual server on a virtualized platform. With a PaaS model you develop and deploy your own software platform. Both models make use of the Internet as their virtual operating system.
With an IaaS cloud computing model you need to manage infrastructure, which consists of multiple machines that each have their own operating system and data. You can specify the number of processors, RAM, hard drive size, network bandwidth and processing power real time. You can also associate your cloud service with the appropriate external IP address for each machine. Multiple cloud servers can simultaneously spin up at the same moment. You could also store your server images for future usage; when you’re ready to use it again, just open the image and everything that was there, including your application program files, would be available.
With PaaS, you would have to manage and maintain your own infrastructure consisting of hardware, networking equipment and software. You need to have high bandwidth and low latency connectivity to the internet for your workloads to be delivered to your customers. The hardware is typically based on proprietary hardware like servers and workstations. The infrastructure has been built and maintained by third-party vendors and you’d have to hire technical support professionals for software updates and security fixes. For faster application response times and greater levels of availability, you would want your VPS cloud computing services to utilize highly advanced hardware features.
While this solution comes with significant cost savings and flexibility, the main drawback is its lack of hardware scalability. You can only scale up the system to its maximum traffic potential; otherwise, performance will degrade rapidly. Due to heavy programming and resource intensive workloads, even a single instance of a PaaS cloud computing service can easily exceed the available capacity of a single physical computer. For companies with large workloads, this issue can be extremely detrimental to their bottom line.
On the other hand, cloud computing server hardware solutions that feature two CPU sockets and fourGB of RAM for each instance can bring significant cost savings. You could run two instance’s on each machine and divide the workload between the two machines. Each instance of the software and applications can easily consume most of the available RAM in both sockets for increased performance. This setup allows you to have two CPU cores running at maximum utilization for your workload without having to use more than one CPU core for general computing purposes.
Virtualization: Cloud computing service providers like Hypervacle find a common ground in virtualization. Virtualization allows multiple machines to run various operating systems, software, and applications on a single piece of hardware. With cloud computing, virtualization can easily adapt to workloads by using multiple CPU sockets andGBs of RAM. You would only need a single piece of hardware for each instance of applications and programs, allowing greater server density. This virtualization feature helps in better utilization of available RAM and CPU sockets.
