Cloud Testing is a type of testing which is used to test cloud computing Services. The cloud-based applications that are using resources from the cloud are tested by using cloud testing.
These resources can be software, hardware, and infrastructure that are needed to take a quality test. A cloud testing approach offers an end-to-end solution that improves the way computing is conducted and can help a company improve its productivity by reducing research costs without negatively impacting mission-critical development processes.
When using a cloud infrastructure system for testing, companies can shorten the provisioning time as the cloud requires test servers to be supplied on demand. It will ensure that redundant servers don't stay idle.
As a result, cloud testing has become important for validating working device specifications and market needs. Data software engineers need an understanding of various software styles and techniques as well as application expertise.
Types of cloud testing
There are four types of the whole cloud testing:
1.Testing of the Whole Cloud:
The cloud is treated as a single system and is tested depending on its functionality. Cloud and SaaS providers, as well as end-users, are involved in running these testing.
2. Testing within a cloud:
Tests are carried out by checking each of its internal features. Only cloud vendors can do such testing
3. Testing across cloud:
Testing is done on various kinds of cloud-like private, public and hybrid clouds
4. SaaS testing in the cloud:
Functional and non-functional evaluations are conducted according to the program criteria.
Core Components of Cloud Testing:
Application: It contains function testing, end-to-end business processes, data protection, compatibility with browsers, etc.
Network: It includes testing different network bandwidths, protocols, and successful data transmission via networks.
Infrastructure: This includes checks for emergency recovery, backups, safe communication, and transport. The network needs to be checked for conformity with the regulations
Methods of Cloud Testing:
There are different methods according to the different types of cloud testing:
1.SaaS or Cloud-oriented Testing:
Usually, cloud or SaaS vendors perform such testing. The primary goal is to ensure the consistency of the software services that are offered in a cloud or SaaS system. Testing carried out in this environment is integration, functional, safety, unit, validation of system function and regression testing, as well as evaluation of performance and scalability.
2.Online based application testing on a cloud:
Virtual platform providers perform this test that tracks cloud-based applications' performance and practical monitoring. Once programs are related to legacy networks, the consistency of the communication between the legacy network and on a cloud is checked under check procedure.
3.Cloud-based application testing over clouds:
This type of testing is performed over different clouds to evaluate the reliability of a cloud-based application.
Strategy Components of Cloud Testing:
Quality and Load Testing (Longevity Testing): Ensure a cloud system addresses domain-specific business requirements.
Stress testing and recovery testing: Ensure recovery of data following a hardware crash
System integration testing (SIT): includes areas of design
Security Testing: guarantees a cloud system satisfies requirements for data security
User Acceptance Testing (UAT): Makes sure the cloud solution meets the firm's documented demands.
Interoperability and compatibility testing: Ensure the integration between cloud and product resources
Models:
There are three models of cloud computing that we are going to discuss shortly:
SaaS:
Also known as Software as a service. It is a model that provides quick access to cloud-based web apps. The provider manages the whole stack of computation and can be viewed through a web browser. These applications are running on the cloud and you can use them with a paid licensed subscription, or with limited access for free. SaaS does not require any modifications or upgrades in the current software network. This eliminates the need to install applications on each of your computers, with the vendor taking over the maintenance and support. Some well-known SaaS examples include Google G Suite, Microsoft Office 365, Dropbox, etc.
IaaS:
Also known as Infrastructure as a service. This is simply a software supply of cloud storage services. In addition to servicing and support, an IaaS cloud service can provide you with the full spectrum of computing infrastructures such as storage, servers, networking hardware.
Amazon Web Services, Google Compute Engine, and Microsoft Azure are among the major suppliers of cloud computing to IaaS.
PaaS:
Also known as Platform as a Service. It is a software platform where various apps for the company can be created, checked, and organized. Implementing PaaS simplifies the process of designing enterprise applications. The virtual runtime environment provided by PaaS gives favourable space for application development and testing.
The whole resources offered in the type of servers, storage, and networking are either manageable by the company or by a provider of the platform. Two typical examples of PaaS include Google App Engine and AWS Elastic Beanstalk. PaaS is also built on subscriptions that offer you flexible pricing options depending on your business need.
Benefits of Cloud Computing:
Yes, you can easily realize that cloud computing services are running in the world
• Reduced maintenance costs – The usage of the infrastructure offered by current Cloud installations removes the requirement for equipment integration and support. Using cloud systems enables IT resources to be centralized. Any maintenance steps will only have to be performed once, centrally, and will be mirrored on all end-user instances.
• It is important to take into account the extra time and/or staff needed to perform exhaustive tests on all the devices.
• It is important to provide a clear list of devices that need quality assurance. The business-will also devotes itself to promoting all target platforms and operating systems
• Location-independent access – The use of thin clients or virtualization helps reduce hardware requirements, allowing the services to be tested anywhere.
