An Insight into Cloud Testing

Cloud testing is a form of testing in which applications use cloud computing

environment and cloud infrastructure. The cloud infrastructure includes hardware and

bandwidth that closely simulates real world conditions and parameters. Testing a Cloud

includes availability, security, performance, interoperability, disaster recovery, and

multi-tenancy testing. Testing is performed in three distinct areas of cloud that includes

infrastructure, platform and service. Organizations and enterprises face a lot of issues

with testing such as limited test budget, lack of meeting the prescribed timelines in

addition to high costs per test. Cloud testing facilitates services to clients based on

internet and delivers services like resources, software, and information by leveraging

cloud computing resources and models to enable all aspects of testing in a highly cost

effective manner. The aim of cloud testing is to ensure high quality service delivery and

help avoiding data outages by comprising of testing inside, outside, or either, in a

datacenter.

A typical cloud environment handles high increases in load by dynamically scaling to

more physical resources based on the need. It runs on a virtualized hardware and a

software stack that can be moved and replicated between machines as needed. It

provides API’s for integration and management and is built to be highly scalable in real

time. However, to successfully provide cloud services and sharing of resources, the

cloud must be tested. Cloud testing is testing cloud-based applications as a service and

IT organizations that deal with testing products and services make use of cloud-based

licensing models for clients. There are some cloud testing challenges like securitychallenge, layered testing challenge, scalability issues, lack of universal standards,

guidance, and limited infrastructure that needs to be taken care of while cloud testing.

Benefits of Cloud Testing

With organizations adopting cloud services, they definitely get the benefit of quick

access to data whenever needed without experiencing any undue delays. It also helps

users’ data to be moved to large data centers, which are remotely located, with the user

being able to access the same anytime needed. Further, it reduces direct price of

equipment maintenance and management and helps attain rapid ROI on applicationassets and brings about faster time to market.

Disaster Recovery in Cloud: Today, there is a new concept of cloud that is based on

virtualization wherein the entire server including the operating system, applications,

patches and data are encapsulated into a single software bundle or virtual server. This

virtual server further can be backed up to an off-site data center within no time. Since it

is a virtual server without any need for hardware, data can be safely transferred from

one data center to another without the burden of re-loading to the server. This candramatically reduce recovery times compared to conventional (non-virtualized) disaster

recovery approach as the server need to be loaded with the OS and later need to be

configured. With cloud computing, disaster recovery becomes more cost effective with

quicker recovery times.

Multi-Tenancy in SaaS Cloud Computing: In cloud computing, multi-tenancy represents a

Software as a Service (SaaS) and the vendor provides a single version of its software for

all its customers. Under

multi-tenancy architecture, a single instance of a software application serves multiple

customers wherein each customer is a tenant. Under cloud computing, the multi-

tenancy architecture has broadened due to new service models that take advantage of

virtualization and remote access. The SaaS provider can further run one instance of its

application on one instance of a database and provide web access to multiple customers

and each tenant’s data is isolated and remains invisible to other tenants. It lowers the

costs through economies of scale.

Cloud Testing Models

There are 3 models named as Infrastructure as a Service (IaaS), Software as a Service

(SaaS), and Platform as a Service (PaaS). IaaS is a typical platform virtualization

environment as a service. It can be represented as a fully outsourced service wherein

client purchases servers, software, data center space, and other network equipment.

With respect to SaaS, the cloud provider offers complete applications over the internet

and service is paid on a unit basis with the Pay As You Go model. With the PaaS model,

the service facilitates to help enterprise developers to quickly write and test customer

or employee facing web applications.

There are different types of deployment models such as public cloud (services can be

found by the third party through the web), private cloud (arranging of privately used

applications emulating a cloud over the web), and the hybrid cloud (- which is a

combination of public and private clouds).

Types of Cloud Testing

1.  Functional Testing: It is performed for both remote and local applications. It

consists of testing all features and functions of the system that includes hardware

and software testing. The different types of functional testing are System,

Integration, and User Acceptance Testing.

2.  Non-functional Testing: This type of testing is done to ensure that a web

application meets the specified performance requirements. It includes Security

testing, Stress testing, Load testing, Performance Testing, Browser testing,

Latency testing, Availability testing, Business Requirement testing, and more

Cloud Testing Tools

The right choice of testing tools really depends on multiple parameters including client

application architecture, context, and client needs. Some of the most commonly used

Cloud testing tools have been given below.

Finally, it is true that the future for all large as well as small businesses will be aroundcloud computing solutions on a large scale. There are many advantages with cloud-

based applications and with the advancement of cloud technology, cloud testing is

emerging as Testing as a Service (TaaS). Thus, innovative cloud testing techniques,

solutions and certain standards are needed to support on demand testing services in a

cloud infrastructure.
