Cloud Computing

The systems administrator role:
The systems administrator role is perhaps one of the earliest in technology, at least as far as the implementation of a system goes. In the earliest days of computing, electronic technical professionals built prototype computers. In time, the systems administration role owned the installation, configuration, operation and tuning of these systems once they went into production and use on a larger scale.
A few of the tasks associated with the role are:
1. Planning, installing and configuring systems.
2. Planning, designing and creating storage, networking and other system components.
3. Planning, designing and implementing high availability and disaster recovery for each system.
4. Maintaining and monitoring systems.
5. Implementing performance tuning systems based on monitoring.
6. Re-balancing workloads across servers based on monitoring.
7. Securing systems, networks and individual computers based on requirements and implementation.
8. Planning, implementing and controlling user and account security rights and restrictions.
How the cloud changes things:
The systems administrator has the same concerns and impacts of the cloud as the DBA and the systems architect. They need to educate themselves on the options within this new option, try a few test solutions out and of course work with others on various parts of the implementation.

Hi Afreen,
Cloud computing is the delivery of computing and storage capacity as a service to a community of end-recipients. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts services with a user's data, software and computation over a network.There are three types of cloud computing:
1.Infrastructure as a Service (IaaS),
2.Platform as a Service (PaaS), and
3.Software as a Service (SaaS).
Employers will want you to have exposure to or experience working with the technologies of one of the four big cloud computing companies: Amazon, Google, Microsoft or Salesforce.com, and/or experience working with virtualization technologies such as that of VMWare.
Other requirements may include:
BA/BS degree in engineering, computer Science or related field;
Network and security architecture experience;
Experience with a cloud migration, data center migration, or server consolidation project;
Knowledge of and experience with technologies such as Java, Web services, SOAP and Ajax;
communication, teamwork and problem-solving skills.
Hope this information helps.
Wish you luck.
