Challenges of Testing in a Cloud Computing Environment
Here, find out how to get around some of those obstacles. Cloud computing can be intimidating even today. Testing in cloud environments can also be challenging. However, cloud services, in my opinion, are the right direction and will enable businesses in transitioning from the Industrial era to the Data Accessibility era.
Which are the clearest examples of operating in a Cloud-based surrounding?
Sending or gaining access to some work-related documents outside of your office.
Accessing your bank accounts and conducting transactions while on the road.
While commuting, update your Facebook and WhatsApp statuses.
Business continuity and disaster recovery (BCDR).
Software product updates on the go.
Siri, Alexa, and Google Assistant.
These and numerous other advantages are now enabling small, medium, and major corporations to remedy small and large challenges in order to reach their full potential. Furthermore, there are some obvious reasons why both large businesses around the world are migrating to the Cloud. Efficiency, adaptability, disaster management/recovery, incredibly simple feedback, improved partnership, anywhere/anytime access, competitive edge; it also inspires making the workplace more eco-friendly.
If you're still not convinced of the popularity and efficiency of cloud solutions, consider the following staggering statistics from recent studies:
By 2025, there will be over 100 zettabytes of data stored in the cloud.13 To put this in perspective, a zettabyte is a billion terabytes (or a trillion gigabytes). In the same year, the total global data storage will exceed 200 zettabytes of data, meaning that around half of it will be stored in the cloud. By comparison, only 25 percent of all computing data was stored this way in 2015.
In 2020, the total worth of the market was $371.4 billion. With a compound annual growth rate (CAGR) of 17.5 percent, it’s projected that the market will amount to $832.1 billion by 2025.
In 2020, the combined end-user spending on cloud services totaled $270 billion. In 2021, this is expected to increase by 23.1 percent to a staggering $332.3 billion. By 2022, projections indicate that this figure will rise to $397.5 billion.
A multi-cloud strategy revolves around utilizing multiple cloud service providers such as Google Cloud or AWS. This way, if one of the services is unavailable for whatever reason, the organization can switch to a working backup for disaster recovery. Because of this, 92 percent of organizations already have a multi-cloud strategy.
In the first quarter of 2021, cloud services infrastructure spending increased to $41.8 billion on a global level. Compared to the same period in 2020, this was a 35 percent year-on-year growth and a five percent quarter-on-quarter rise. To break this down in financial terms, around $11 billion more was spent than in Q1 2020 and almost $2 billion more than in Q4 2020.
At the same time, the cloud computing environment presents a number of challenges that organizations must address. While the purpose of this article is to discuss the testing challenges in the cloud computing environment, it is critical to get a quick grasp on the challenges that the cloud poses:
Quality: Because specific cloud services are outsourced to third parties, businesses are hesitant to move mission-critical applications to the cloud. There are concerns about issues such as availability, accessibility, performance, and scalability.
Performance: There is some concern about the network bandwidth provided by cloud services. Because cloud applications continue to be bandwidth-intensive, this may have a negative impact on their execution and delivery.
Security: While the cloud environment provides you with a ready backup and a robust disaster recovery plan, there has been persistent concern about the security of hosting your data on the cloud. It is one of the most frequently mentioned concerns by users, as a significant portion of services is outsourced. As a result, risks such as data integrity and service availability arise.
ROI: Despite the fact that cloud computing provides a higher ROI, businesspeople are concerned about the commercial viability or business outcome of cloud adoption. Nonetheless, this aspect can be addressed by aligning it with the organization's goals for adopting cloud services.
While comprehensive testing frameworks and practices enable enterprises in creating the most of their cloud-invested capital, there are a number of challenges associated with cloud testing. The most important aspect to consider during testing is ensuring that the specific functional requirements are met. Let's take a quick look at the two most important aspects of cloud testing.
Functional testing: This permits you to assess and focus on ensuring that you are gaining the most value for your money. It also confirms that the business requirements have been fulfilled. Functional tests such as system verification, acceptance, and interoperability testing ensure that business requirements are fulfilled.
Non-functional testing: This process relies on web application-based tests that help guarantee that all intended results are encountered. Availability, performance, security, recovery, and multi-tenancy tests are all important aspects of non-functional testing.
The challenges of working in the cloud intersect with the hurdles of testing cloud-based applications. The possible explanation for this is that it actually involves testing applications across various functionalities and environments in order to detect problems. The preferred option is to use cloud-based test services, which provide the necessary testing environment. Choosing to rely on the cloud for performance and all of its benefits is a conscious decision made by businesses.
Drilling down, let's concentrate on comprehending the testing challenges in order to effectively address them:
Replication of test and development environments: The applications and services to be tested are installed in an environment outside of the team's control. The team is expected to test the applications in scenarios similar to those in which the user would operate. This makes it difficult for engineering teams to create a similar testing environment.
Performance Issues: Any application relies heavily on performance. Downtime in the cloud has a direct impact on the performance of cloud-based applications. An outage is possible with any technology. Several cloud vendors have failed in recent years. Customers find it difficult to rely on such providers in such circumstances.
Inadequate resources or expertise: One of the most common cloud struggles that enterprises and organizations face these days is a lack of expertise or resources. Because of these factors, businesses are having difficulty keeping up with technology and skills.
Security Challenge: When using these cloud-based applications, the security of confidential data remains a major concern. We may encounter situations such as the leak of private information or the internet being suspended due to a virus attack or slow internet speed. Another disadvantage of cloud-based outsourcing is that cloud vendors are unfamiliar with security requirements and industry standards specific to government agencies, such as continuous management and system inventory monitoring. While the testing is taking place, the firm must ensure that no data that is accessible via the Internet is leaked. Before releasing business applications to customers, it is critical to have a backup plan and test them.
Interaction between components: Another common challenge is during integration testing, which involves running tests on the network, database, servers, and various systems. When testing applications hosted in the cloud, testers have limited control over the environment. This is exacerbated when all of the modules interact, potentially resulting in a collision, network breakdown, or server crash. To ensure that different software solutions operate effectively and safely on the cloud, it is critical to comprehend and address these challenges with a clear perspective. Furthermore, it is critical to confirm that the entire process aids in gaining a competitive advantage in the marketplace. Regardless of the current challenges, cloud computing will enable and sustain organizations to stay ahead and competent.
Governing Compliance: Compliance with governing rules and regulations is critical to ensuring the security and accuracy of information flow in the cloud. For Example:
Sarbanes-Oxley Act of 2002 (SOX),
Health Insurance Portability and Accountability Act (HIPAA)
Industry Data Security Standard (PCI DSS)
