QA CHECKLIST YOU SHOULD GO THROUGH FOR A SUCCESSFUL MIGRATION
The key business drivers behind moving workloads to cloud vary from one organization to a different . It might be an intention to enhance scalability and performance, or just to scale back organization's upfront investment by assigning IT infrastructure responsibilities to at least one of the trusted service providers like Microsoft Azure, Amazon (AWS), IBM, Google or Oracle. The reasons could be many, some of them are outlined in this article.
Once you've got decided to maneuver your products or services to the cloud, testing may be a crucial step within the cloud migration journey. It avoids cloud scalability issues, server breakdown issues like application or website crash or database errors and more, which may be extremely risky in terms of brand's reputation, time and resources.

With that in mind, business owners or IT decision makers should properly plan and perform their cloud migration journey while putting Testing in top priority during cloud migration regardless of environment.
Addressing Key Challenges That Arise While Validating Applications
Cloud migration throws certain challenges in validating applications. Some of the instances and the way to validate them at various aspects are discussed here.
Functional validation or cloud-ready validation assesses production readiness of migrated applications. It is fundamental to verify if various aspects of the migrated applications are performing as per SLAs. For an efficient cloud migration, validate SaaS/Cloud services functions and perform end-to-end application's function validation. Check the subsequent test cases to perform functional validation of an application for cloud testing:
Automated test suite is compatible with the appliance over the cloud
Whether a valid input gives the expected results
Service integration with other applications
Page layout and object references are working needless to say
Cross platform compatibility is ensured
Integration Testing (With Third-Party Applications)
Cloud migration isn't just moving data, but it's managing a variety of variables - security, authentication, integration, compatibility, testing and monitoring over time. Among the above variables, integration with third-party tools plays a big role. Because, today, there are many technology choices with cloud integration than ever before.
But, the dependencies between systems and applications can complicate integration testing. If you're integrating tons of services together that accompany varying SLAs, testing within the cloud with a plethora of third-party tools, services and applications represents a serious challenge. To avoid such issues, make sure you undergo the below checklist and validate them effectively:
What systems will get affected when integration testing is performed?
What resources you would like to try to to the validation and integration testing?
Have an idea to develop and execute tests in parallel with the software
Perform Integration Testing early
Detect coordination problems in cloud environment - this is often to make sure the applications are well configured with cloud environment
If you do not have in-house expertise, confirm to outsource validation for integration to your cloud provider or a managed service provider who fills the gap.
One of the main deterrents to migrating to the cloud is Security. Applications are often very secure within the cloud, but unlike conventional storage you'll not have any hardware. This means, you don't have complete control over the data. To keep the info secure within the cloud requires an entire new level of security procedures and methods .
 If you're planning for an Infrastructure as a Service (IaaS) architecture, make sure you check whether your workloads are often migrated to the cloud; or will there be any significant difficulties after migration. Following checklist are often handy to crosscheck some cases:
If you've got legacy applications running on outdated platforms
User validation - make sure the applications are accessible only by authorized users and are available only to them
Protective measures against Distributed Denial of Service (DDoS) attacks
Validation of knowledge security at rest, in use and through transit - almost inevitably, the info goes to spread across multiple networks and devices after migration, with varying levels of risk and security. Before you'll take an efficient decide to completely avoid risk, here's a checklist or questions you would like to possess answers:
What sort of sensitive data does one use, store or transfer?
Who has access to this data?
Why, when and where the users access this data?
How is data stored when it is idle?
How data access is controlled?
What are compliance requirements?
Various aspects of application Security Testing include: Data security and data privacy testing, application transaction security, business process security and user privacy security testing.
Assessing performance and reaction time requirements of applications and workloads while migrating to the cloud may be a significant factor determining cloud migration success. There are areas that affect moving an application to a cloud service, a number of them include: reaction time implications and scalability factors. Check out the below steps to make sure workload performance and SLAs are met:
Identify and document business transactions and application's end-to-end flow
Identify business SLAs for the business transactions
Examine if your software comes with limited internet bandwidth or intensive CPU and input-output capacity requirements
Address application's architecture that is not appropriate with the cloud
Identify monitoring requirements and setup tools
Validate response times as per SLAs - perform Load Testing in parallel and validate whether applications or service performances under various loads are meeting the SLAs
Disaster Recovery Plan and Business Continuity Plan
Be prepared for the worst-case scenarios within the cloud, from simple data recovery and disaster recovery practice to an idea addressing unique incidents of attack. Validate all of your disaster recovery plans within the event of cloud outages.
Test, measure and update business continuity processes periodically
Perform tests to run simulations and evaluate team's readiness
Consider the test results to vary or update your business continuity plan over time
Validate application instances to revive automatically during hardware failures
