From the Administration point of view on cloud, there is a significant change in the Oracle DBA role in this cloud era as organizations are shifting to IaaS, DBaaS or hybrid architecture. In this series, we will discuss where Oracle DBA should focus and what skills they need to learn. It mainly focuses on relational Databases and talks about managing database and other services on Oracle cloud.
The three broad categories in which Cloud Computing has been divided are: SaaS, PaaS and IaaS.
Cloud Computing
A) IaaS stands for Infrastructure as a Service, involves software and hardware combinations to build everything on your own. Three main part of computing i.e. CPU, Memory and Disk can be rented/provisioned on the cloud. Example of IaaS are Amazon’s S3, Google Compute Engine, Oracle Storage Cloud, or Oracle Bare Metal Cloud

B) PaaS stands for Platform as a Service, involves tools and services to develop and deploy applications. Example of PaaS are Google App Engine, Java Cloud Service, Database as a Service, etc.

C) SaaS stands for Software as a Service, involves a ready-made application to be used by its end-users. Example of SaaS are Gmail, DropBox, Oracle Fusion Applications, SalesForce, Workday etc

There is another service as well which is DBaaS – Database as a Service which is important to Oracle DBA and Developers. Will talk about it in upcoming blogs.
