What is cloud computing?
Definition: Cloud computing refers to a centralized delivery
system of computing services, be it information, resources or software
over the “cloud”, i.e., the Internet. Storing and accessing data over the
network rather than a computer is what cloud computing essentially
means.

Cloud Service Models

Description
● Infrastructure as a Service (IaaS) : The first layer and base of cloud
computing is Infrastructure as a Service, wherein one manages the servers,
storage, virtualization, networking and operating systems. Example: U-Cloud,
VMware, Amazon Cloud (AWS), RackSpace, etc.
● Platform as a Service (PaaS) : The second layer of the cloud service model
is known as Platform as a Service wherein one manages the applications and
the third-party cloud vendor manages the rest, such as servers, networking,
storage, etc.. Example: Google App Engine, Windows Azure, etc.
● Software as a Service (SaaS) : The final layer of this model is known as
Software as a Service wherein the third party cloud vendor manages all the
applications and data allowing the business to access the interface. Example:
Google Docs, Gmail, Cisco WebEx, etc.

Key Characteristics of Cloud

Cloud Testing
Cloud testing becomes ubiquitous wherein resources such as the software,
hardware, etc., are checked in a thorough testing effort.
Due to certain challenges like:
● High costs
● Restrictive budget
● Numerous test cases
● Various users across the globe, etc.,
Effective testing becomes essential wherein availability of flexible and scalable
infrastructure, distributed test environment or unlimited storage helps in saving
time as well as the cost.

Common Testing performed on Cloud
● Functional testing – To verify the basic functionalities with respect to the valid input
that should match the expected output such as user login, shutdown of system,
etc.
● Load testing – To ensure stability with a number of users accessing the cloud. With
scaling-in/scaling-out, load testing is conducted to handle variable load.
● Performance and Benchmark testing – To establish certain yardsticks considering
the performance of the application such as consistency across devices.
● Network security testing – Testing in terms of network connectivity, maintenance of
data integrity, protocol, etc., becomes imperative to ensure a secure environment.
● Interoperability and Compatibility testing – To test seamless functionality across
browsers and platforms.

Conclusion
Cloud computing becomes an effective way to-
● Create surplus
● Lower the costs
● Help small businesses and startups wherein they don’t have to bear the initial
infrastructure expenses
● Build, operate and use IT business systems
However, it does pose certain challenges with respect to security, reliability, interoperability,
etc., which need to be taken into consideration.

A Glimpse into the Future
● Focus on multi-cloud management
● Development in domain-specific cloud services
● Growth in application migration
● Increased focus on areas such as performance and security
● Change in healthcare, local businesses, real estate and many more
