Description

We use many applications in our daily life like email, Web, social media apps, games, learning, research and analysis, media and many more. Ever thought of from where these applications are being served off?

Every application would be running from a server installed in an Enterprise IT center or data center. This server would consist of the components like Multiple processors, Memory Chips (or RAM), Hard disks or SSD, Input Output Cards, Network Interface Cards, etc.

The course covers concepts like Redundant Array of Independent Disk (RAID) and Logical Unit Number (LUN) in detail. Various storage technologies like Direct Attached Storage (DAS), Fiber Channel Storage Area Network (FCSAN), IP Storage Area Network (IPSAN) and Network Attached Storage (NAS) are covered in the course.

Virtualization has given a way to mitigate the wastage of resources and improve ROI. The advantages of virtualization are:

Resource consolidation
Agility
Development Flexibility
Migration and Cloning, and
Desktop Virtualization

The course includes Network Virtualization, Storage Virtualization and Server Virtualization.

On the foundation of the above-mentioned concepts, the course now turns towards Cloud computing which is defined as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Major Service models of cloud computing are:

Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software as a service (SaaS)

These service models are discussed in detail in the course. Other concepts related to Cloud like storage and deployment models are also covered extensively.

Apart from all this Cloud Monitoring is an important aspect which needs to be considered in this domain. Cloud monitoring system refers to a set of programs, software, and applications that offers capability to monitor smallest to biggest elements of Cloud with number of benchmarks, thresholds, and nature of alarms.

Cloud monitoring includes the following concepts:
