Guide To Creating A Cloud Migration Testing Strategy

Using the right strategies and tools at the right time and avoiding common mistakes is the only way to ensure the success of the migration process. Once the initial data load has been performed, incremental data syncs are run for migrating changes until the application migration has been completed and the legacy applications are switched off. These test cases can be added to a test plan and invoked from your CI/CD process. Migrating live apps – Migration of live apps that are being used currently by end-users is highly challenging as the migration should not impact the performance of the apps even slightly. Also, technical teams must ensure that there is no data loss while transferring the apps from an on-premise setup to a cloud environment.

You should implement a good testing strategy for ensuring that your applications are working properly. They should deliver the best user experience in the cloud platform. You should focus on the key factors that we have mentioned in this article.

The client had a requirement to move their current infrastructure to a cloud-hosted solution. These highly benevolent services are offered by many cloud platform providers like Azure, Google Cloud Platform, and AWS. They put an end to high procuring costs and servicing expensive physical devices to test an application/software before being released in the market. Organizations give very short timelines to the teams to successfully implement a Data Migration project. And giving users the ability to accelerate the testing of these Data Migration processes helps them shorten that timeline easily. Therefore a feature to create tests for 1000’s of tables with a click of a button addresses this pain point.

Cloud migration is a popular term that embraces all the above-mentioned cases, if they involve moving data from on-premises to the cloud or between different cloud environments. Gartner expects that by 2024 the cloud will attract over 45 percent of IT spending and dominate ever-growing numbers of IT decisions. The re-platforming strategy is somewhere in between simple lift-and-shift and a more Cloud Data Migration profound re-architecture of the application. Thus, the alterations in the codebase are more likely to be minor and are not supposed to change the core app functionality. For example, you may want to add new features or replace the application components. Although these changes don’t significantly alter your project, you can improve InfoSec posture and get feature and tooling enhancements.

Big Data Migration To The Cloud: Testing Challenges And Strategies

If you are not modifying your applications, then they will become slower with time. These tools will help you in checking the historical performance data. Also, it is important to check the security of applications and data.

A solid transfer plan, comprehensive cloud testing, and providing a high level of security can allow you to be confident in new storage format and information privacy. Solid data protection may be enabled by harnessing more powerful software. However, occasionally users uncover their credentials by accident so that the responsibility falls on the company. Two-factor authentication assuming several steps of login can help avoid such cases. For instance, firstly utilize username and password, secondly — a special code sent over SMS. The engineers review feature by feature and verify whether it complies with the set requirements, integrates seamlessly with the corporate environment, and meets users’ expectations.

You’ll always have access to the latest features, improvements, and security updates without the need for manual version upgrades. Download our Becoming an Atlassian Cloud admin guide to learn more about making the transition. To help determine your timeline and budget, it’s good to have a general understanding of how long migrations can take. Migration timelines can vary greatly, depending on the complexity of your migration, the strategy you choose, and the budget and resources you allocate to the project.

Among popular solutions are Open Studio for Data Quality, Data Ladder, SAS Data Quality, Informatica Data Quality, and IBM InfoSphere QualityStage, to name a few. The big bang approach allows you to complete migration in the shortest possible time and saves the hassle of working across the old and new systems simultaneously. However, in the era of Big Data, even midsize companies accumulate huge volumes of information while the throughput of networks and API gateways is not endless. Choosing the right approach to migration is the first step to ensure that the project will run smoothly, with no severe delays. The latter case is tougher than the former, especially if target and source databases support different data structures. It makes the task still more challenging when you have to move data from legacy databases — like Adabas, IMS, or IDMS.

Cloud Migration

Some things to look out for might be inactive apps or users, old product data such as projects, customizations, or workflows that can be simplified or left behind, and any duplicate data. Now that you have your plan together, it’s time to prep your team, environments, and data for the big move. This phase can take time — anywhere from days to weeks — so make sure you leave enough time to complete this section.

Downtime or missing data in a botched application migration can negatively affect revenue. Application migration testing applies to all types of migrations, including application consolidation, development and lift and shift migrations. The goal is to ensure legacy data transfers over to the new application with minimal downtime or disruption with all essential data and functions intact. It also makes sure the new, upgraded application is compatible with all hardware and software your legacy application currently supports. Application migration testing compares the migrated application with your legacy application to uncover discrepancies or errors.

Deliver Cloud

Track them down and explain the need for this project and the impact on them before you get going on the task. If you don’t, you’ll certainly hear from them at some stage, and chances are good that they’ll disrupt your timeline. This may appear to be an overwhelming amount of work, but not all these steps are needed for every migration. Each situation is unique, and each company approaches the task differently. The Query Wizards can help your team validate data with no coding required – and it’s all performed graphically through the QuerySurge interface.

• When evaluating which of the “6 R’s” is right for your organization’s migration needs, keep in mind that every cloud migration is unique.
• This is a significant element of an organization’s cloud migration success while also being a critical part of application development.
• Companies gather information for decades, and when the data migration time comes, its volume may be unprecedented.
• It is assumed that a specific business target will be set from the beginning, e.g. in terms of availability or reliability of the application performance.
• Given the sophistication and sheer volume of cyberattacks, advanced cybersecurity measures must be put in place to ensure confidential organizational data is secure.

Alternatively, if data is transferred in trickles, execution will take much longer but, as we mentioned before, with zero downtime and the lowest possible risk of critical failures. Though several technologies can be used for data migration, extract, transform, and load is the preferred one. It makes sense to hire an ETL developer — or a dedicated software engineer with deep expertise in ETL processes, especially if your project deals with large data volumes and complex data flow.

Stay Ahead Of The Curve With The Latest Insights In Testing, Qa, And Automation

For some companies, this step may happen sooner depending on the criticality of the products being migrated. It’s also best to establish a communications cadence for when, and how often, you’ll be communicating updates so teams are informed and prepared for the change. With years of experience handlingcloud testing services, here we bring you the list of 10 key elements that make it to successful cloud migration. This type of migration is driven by mergers and acquisitions, business optimization, or reorganization to address competitive challenges or enter new markets.

Concomitant process security is noteworthy as information can be restored easily due to data backup. If you run into blockers or need guidance throughout the migration phase,contact our migrations support team for help. In this phase you’ll do a test run and make https://globalcloudteam.com/ sure everything is in order, figure out how long the migration will take, and uncover any issues before the production migration. The more data you migrate, the longer and more complex your migration is likely to be, and could affect Cloud performance later on.

In this strategy, you change the proprietary application in use for the new cloud-based platform or service. Often, that means that you drop the existing license agreement and go for a new platform or service in its place. For example, you may choose to switch from your legacy CRM system to a new SaaS CRM that meets your organization’s requirements better. Replatforming involves certain optimizations to the operating system, changes in the API of the applications, and middleware upgrade as you do standard lift-and-shift. As a result, you can leverage more cloud benefits, reshape the sourcing environment and make it compatible with the cloud, fine-tune the application functionality, and avoid post-migration work. We offer a layered & automation first approach to validate transformations that leverage Poly/ Multi Cloud deployment models (Public, Private, Community & Hybrid) and service models (IaaS, PaaS & SaaS).

So, you need to perform a high-level analysis of source and target systems, in consultation with data users who will be directly impacted by the upcoming changes. Systems are down and unavailable for users so long as data moves and undergoes transformations to meet the requirements of a target infrastructure. The migration is typically executed during a legal holiday or weekend when customers presumably don’t use the application. The key challenge here is that old and new infrastructures may have unique data models and work with different data formats. The primary reason for this shift is a pressing need for technology upgrades rather than a lack of storage space.

Migrating business applications to the cloud can vastly improve efficiency and security, but the task of transferring vast amounts of data can appear daunting. Your team lead should define all the common challenges that will occur during application validation. You need to deal with challenges like application security, performance, and application compatibility.

New Testing Show Podcast: Test Coverage

Test migrations are the initial piece of a cloud migration strategy. Offering an unlimited number of test migrations to the target environment allows users to build confidence before a final cutover and avoid any downtime. Another term that is sometimes confused with data migration is data integration. Data integration refers to the process of combining data residing at different sources to provide users with a unified view of all the data. Integrating data from multiple sources is essential for data analytics.

What Is Cloud Migration? An Introduction To Moving To The Cloud

In a Cloud world, your admins aren’t tasked with the same manual upkeep as they did in self-managed. Moving forward, your team can take on more strategic and proactive roles to stay ahead of your company’s needs and focus on supporting your teams as they scale. The day is here to embark on the most highly anticipated step in the migration process. In this phase you’ll resolve any last-minute issues, run your production migration, and move your users and data over to Cloud. Be sure you’ve completed thepre-migration checklistandtest migrationbefore beginning this step. A cloud testing service provider on your way to cloud migration could help you with Pre-migration advisory, Assurance during migration, and validation of the system after the migration is achieved.

How Could Quality Assurance Help With Cloud Migration Goals?

A report by Gartner forecasts that worldwide public cloud revenue will grow exponentially through 2022. Moving to the cloud is a smarter way to get better and faster service at less price. And, this is only possible once all the boxes in the checklists mentioned in this article have been crossed and you follow the steps of each testing area correctly. Testing the objectives/validations and approaches that were mentioned in the above cloud assessment checklist could be quite tough.

Also, single cloud integrations are easy as they only need your technical team to focus on a single set of cloud APIs. However, working on a single vendor solution often involves downtime as any situation like server issues or closing of vendor brand would make you compromise a lot with your operations. On the contrary, using a multi-cloud approach could help you avoid all such issues but may need you to spend a little extra on the entire development, deployment, and maintenance process.

On the whole, elaborate and rigorous software testing is an integral part of the cloud migration process. The businesses must implement robust cloud migration testing strategy to ensure their applications are running flawlessly in the cloud environment and delivering optimal user experience. The decision makers must focus on these key factors to make and implement the cloud migration testing strategy more effectively.

The team needs a strategy for adding this missing information en-masse, and the approach has to be tested. Re-host – rehosting is perhaps the easier migration type as it requires the migration of a workload as it is to the cloud. To dampen the workload, Quality Assurance teams are using test automation to make sure the core task of moving data has been done properly. The process of checking the structure and the data for issues between the source and target data source is called Data Migration Testing.

The IT head should ensure that they are deploying the required resources, tools, and personnel. While making the cloud migration testing strategy, the managers must remember that cloud deployment and testing are ongoing processes. The applications need to be modified and updated at regular intervals to deliver optimum user experience. Each time the application changes, the testers need to conduct load, performance, and security testing. Also, they need to assess an important aspect of the application at least once a quarter. The cloud migration testing strategy must facilitate regular and elaborate testing by allocating the required personnel, tools, and resources.

Assess Apps And Integrations

Cross-object dependencies.With the technology and capabilities of data management tools available today, it’s still shocking to learn about a dependent dataset that wasn’t included in the original plan. Because cross-object dependencies often are not discovered until very late in the migration process, be sure to build in a contingency for them so that your entire delivery date isn’t thrown off.
