Cloud Computing
Definition
Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure as a Service, Platform as a Service and Software as a Service. The name cloud computing was inspired by the cloud symbol that’s often used to represent the Internet in flowcharts and diagrams.
A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic — a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.
Comments Off Performance tuning of linux server
We know that we have limits for number of open files, number of processes, memory etc. We can see all the details by command ulimit -a, which gives output for example.
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 8127
Red Hat the New VMware
Red Hat Enterprise Linux now comes with built-in virtualization (KVM) but is Red Hat Enterprise Virtualization (RHEV) about to go to the virtual mat with VMware? If you look at their RHEL video, you’ll come away with a resounding ‘Yes’ to that question.
Red Hat purchased Qumranet in 2008 to acquire their KVM-based virtualization solution and SolidICE product based on the SPICE protocol.

Comments Off What is Virtualization?
Virtualization is software technology which uses a physical resource such as a server and divides it up into virtual resources called virtual machines . Virtualization allows users to consolidate physical resources, simplify deployment and administration, and reduce power and cooling requirements. While virtualization technology is most popular in the server world, virtualization technology is also being used in data storage such as Storage Area Networks, and inside of operating systems such as Windows Server 2008 with Hyper-V.
Virtualization Advantages:
- Server consolidation
- Reduced power and cooling
- Green computing
- Ease of deployment and administration
- High availability and disaster recovery
