Cloud migration test plan

You can always consider migrating enterprise applications and data, especially in start-ups to the cloud to avail benefits in terms of cost, scalabilityconnectivity, security, and simplicity. The cloud platforms even help you to run the software applications and manage data without maintaining expensive on-premise IT infrastructure. You even have the option to choose from several private, public, and hybrid cloud platforms.

Likewise, you can migrate the applications to the cloud in a number of ways. But you cannot move your applications and data to the cloud without implementing a robust strategy. Also, you must plan and adopt a number of important steps to simplify and accelerate the cloud migration process. You can migrate your applications and data to the cloud in a number of ways — rehost, refactor, revise, replace and rebuild.

Hence, it becomes essential to decide the most appropriate migration option. While comparing various cloud migration service options, you must identify the applications which can be migrated to the cloud and the applications which will run on your on-premise infrastructure.

Also, you need to assess the usage frequency, criticality, and workload sensitivity of each application to be moved to the cloud. Once you assess and understand the requirements clearly, it will become easier to decide the best way to migrate. In addition to assessing and understanding the requirements, you also need to test and validate the performance of application workloads. The testing will help you to determine the resources required to run the application in the cloud — storage size, network bandwidth, number of virtual machines.

Also, the test results will make it easier for you to calculate the cost of running applications in the cloud. At the same time, the test results will also help you to decide the best storage services to replace your existing data repository.

However, you need to ensure that the workload testing is performed in the production environment and with real network and security controls.

After determining the resources required by the applications, you must prepare a blueprint of the cloud environment. Also, you need to analyze the entire migration process to prepare a robust blueprint. The migration blueprint will help system engineers to understand the migration process and identify the complexities in the migration process. They can further handle the complexities efficiently to migrate the applications to the cloud efficiently. The will further refer to the cloud migration blueprint to ensure that key software components, functionalities, and data are moved to the cloud.

The system architectures must redesign the application and process architecture to handle the complexities associated with cloud migration. After finalizing the software components, functionalities, and data to be migrated to the cloud, they have to architect and program the application from scratch. Once the applications are reprogrammed, the system engineers have to reintegrate them with the cloud-based application integration.

cloud migration test plan

The seamless integration will help engineers to avoid undesirable consequences after implementing the application in the cloud. There are always chances that the migration process may impact the application or process adversely.

The engineers must perform continuous testing to identify the flaws in the application, functionality, or integration environment. They even need to automate the continuous testing process to assess the applications and processes with varied cloud-specific test cases and scenarios. The continuous testing must be performed immediately after implementing the applications in the cloud to identify and fix the bugs or flaws before any major breakdown. The engineers can even use continuous testing automation tools to test the applications as part of the migration process.

Before implementing the applications in the cloud, the system engineers must back up both macro and micro level programs that function based on the input provided by the enterprise systems. Likewise, they also need to back up the existing data to eliminate the chances of data loss during or after the migration process. The backup data will further help the programmers to deploy and run the applications smoothly after being migrated to the cloud.

The engineers can easily backup the programs and data by availing the redundancy and backup systems provided by the cloud service providers. Once the applications are migrated to the cloud, you must integrate the application, data, and environment seamlessly.Estimate pricing. New Relic for iOS or Android. AWScloud computingcloud migration. In several cases, their teams have struggled or had only limited success in their cloud migrations. But they never gave up and they used the lessons they learned to improve their results in subsequent attempts.

So this post leverages those learnings to build a step checklist of the major areas you need to consider and address to maximize your chances of a successful cloud migration. Before you begin your cloud migration, establish the migration architect role to lead the effort. The migration architect is a system architect-level position responsible for planning and completing all aspects of the migration; their core responsibility should include defining necessary refactoring required to make the migration successful, designing strategies for data migration, defining cloud-solution requirements, and determining migration priorities and production switchover mechanisms.

During the course of a large migration project, there are many decisions and technical plans that must be made, and having a migration architect who is responsible for all aspects of the migration is critical to the success of the project.

When you move an application from an on-premise data center to the cloud, there are two ways you can migrate your application—a shallow cloud integration or a deep cloud integration. Any application changes are just enough to get it to run in the new environment. For a deep cloud integrationyou modify your application during the migration process to take advantage of key cloud capabilities.

This might be nothing more advanced than using auto scaling and dynamic load balancing, or it might be as sophisticated as utilizing serverless computing capabilities such as AWS Lambda for portions of the application.

Cloud Testing : An Overview

Before you begin your cloud migration, address this question: Do you want to pick a single cloud provider and migrate your application so it runs optimized for that single environment, or do you want your application to run on multiple cloud providers? Optimizing your application to work with a specific cloud provider is relatively simple. Your development teams have just one set of cloud APIs to learn, and your application can take advantage of everything your chosen cloud provider offers.

The downside to this approach is vendor lock in. Additionally, having a single cloud provider might negatively impact your ability to negotiate important terms—such as pricing and SLAs—with the cloud provider. But wait, it gets even more complicated. There are several different models for using multiple cloud providers:. One application in one cloud; another application in a different cloud.

Perhaps the simplest multi-cloud approach runs one set of applications in one cloud provider and another set in another. This approach gives you increased business leverage with multiple providers as well as flexibility for where to put applications in the future. It also lets you optimize each application for the provider on which it runs.

Split your application across multiple cloud providers. Some companies choose to run parts of an application in one cloud provider and other parts of it in another. This approach lets you utilize key advantages each provider offers for example, one provider might have better AI capabilities than another, which is known for its database speeds. Build your application to be cloud agnostic. Other companies build their applications to run on any cloud provider.A detailed data migration plan is the essential first step in a successful data migration project to select, prepare, extract, transform and transfer data of the correct form and quality.

Below we outline seven steps to a successful data migration. This pre-planning step can save you from making a critical error during the actual migration process. Once you have an understanding of the data being moved, define the scope of the data migration plan. Conduct an advanced analysis of both the source and target system, and write out a flexible timeline for the project.

Consider whether the data migration will interfere with normal business operations, or contribute to downtime. You may be able to plan the migration to take place after hours or on weekends to avoid interrupting business continuity. Tip : Be sure to communicate with key stakeholders about the timeline and potential down time. Tip : Cloud backup is the safest and most secure backup method.

With your plans to guide you, ensure the right system permissions are applied to allow for successful data migration and extract all data migrating to the target, from source system.

Ensure this data is cleaned to protect target system, then transform it into the proper format for transfer. Closely monitor your data migration during the process, so that you can identify and resolve any problems that arise.

Once the migration is complete, ensure there are no connectivity problems with source and target systems. The goal is to ensure all data migrated is correct, secure, and in the proper location. To verify this, conduct unit, system, volume, web-based application and batch application tests.

To account for this, conduct a full audit of the system and data quality to ensure everything is correct once the data migration process has completed. If you notice errors, missing, incomplete, or corrupt data, restore these files from your backup. Contact Support Remote Support.

cloud migration test plan

As a result, many enterprises migrate their applications and data to the cloud. But before your organization takes that leap, there are a few points to consider. Moving enterprise data and applications outside the firewall and into the cloud is no small feat.

To ensure everyone within an organization is on the same page, cloud migrations typically require an in-depth sales pitch that covers costs, tools, security, governance and talent, among other considerations. While the promise of improved flexibility and scalability makes cloud migrations seem like a can't-miss venture, not every application is right for the cloud.

Legacy applications, mission-critical workloads and sensitive data -- such as credit card information -- may not be suited for the public cloud. However, to take advantage of cloud computing without jeopardizing mission-critical information, enterprises can use either a private or hybrid cloud as part of their data center migration plan.

It's also important to consider the amount of resources each application uses. Public cloud platforms offer multi-tenant environments by default, which means applications share resources. And while autoscaling in the public cloud scales resources up or down based on demand, noisy neighbors can be an issue.

High spikes in demand can also run up bandwidth costs and hinder performance. Cloud migrations reduce hardware and IT staffing expenses.

However, the financial benefits differ for each application. Any application with unpredictable demands -- such as mobile applications -- yield a greater return on investment when moved to the cloud. But applications that use legacy enterprise hardware -- such as earlier versions of an Oracle database -- might actually become more expensive to run as cloud-based apps.

Meanwhile, hidden expenses can be an additional burden for enterprises migrating to the cloud, so organizations need to plan for network and bandwidth costs. Application and cost considerations weigh heavily on organizations as they contemplate a data center migration to the cloud. But choosing the right deployment model is just as important on the cloud migration checklist. The four options you can choose from are:. An enterprise's choice largely depends on its goals. Public cloud provides a scalable environment with a pay-per-usage model, which can control costs.

However, it may not be the best place for sensitive workloads, which are better suited in private data centers where there is additional control and security. Explore how cloud computing reduces costs, increases application performance and more in this quick video.

For those that have a mix of mission-critical workloads and apps that require the scalability of cloud, hybrid cloud offers the best of both worlds. Enterprises can have control over the sensitive workloads on premises and take advantage of public cloud scalability for workloads with occasional spikes in demand.

However, there can be performance and connectivity issues. Lastly, multi-cloud is beneficial for enterprises that want to avoid vendor lock-in and maintain the ability to pick and choose from multiple provider services.

Multi-cloud models give users more redundancy options in which a one cloud environment can fail over to another provider's platform. However, this model requires more management and a wide range of skill sets from staff. The next item on your cloud migration checklist should be to find the right provider. Enterprise goals and workload types should dictate which one to select. And while they all offer comparable services, they're not all the same.

When you compare public providers, some key areas to look at are:. Some important factors to consider when choosing this type of provider are:. However, the most popular service providers aren't necessarily the best fit since they generally aim to meet a broad set of needs.

For example, if an enterprise has a specific vertical market -- such as healthcare -- it may opt to go for a more niche provider that better understands and supports compliance for HIPAA.

A cloud migration can often disrupt an organization's governance strategy. For example, governance methods that worked for traditional on-premises systems probably won't work for cloud-based applications. And, as organizations move data to the public cloud, more responsibility falls on the shoulders of the cloud service providers.The Plan B Group has an absolute focus on providing enterprise-grade Cloud Hosting, Data Centre, Networks and Business Continuity Services, so that our clients can focus on their real work; building a better business.

To help make your transition as smooth as possible, see our cloud migration checklist to avoid any issues. Plan B has a local team of dedicated experts who work on infrastructure migrations all day, every day. To help our customers ensure their journey is smooth, we have put together a list of best practices for before, during and after migrating your infrastructure.

First, let us consider the scenarios in which cloud migration would be a viable option for your business. The biggest advantages of IaaS are scalability, agility and cost efficiency, which make cloud a very attractive proposition for businesses, especially small to medium enterprises.

However, before taking the leap, see our Plan B checklist for what you need to consider and execute before, during and after cloud migration. The most important components of the migration is ensuring that users are able to work and disruption to the business is minimised. If you have the relevant technical expertise in your organisation to move to IaaS, our checklist should help make things easier. As you go through the checklist, if you find that you do not have the resources to complete any of our best practices, it is the right time to bring on-board a cloud partner.

Get to know your chosen partner. Know who the key people are and who will be supporting you during the migration. Your chosen partner having a solid understanding of your requirements and environment can make the difference between a successful cloud migration and an unfortunate tragedy.

Prior to migration, it is important to assess what resources are currently assigned to your applications and what the user satisfaction or Apdex measurement of each application is. This will give you guidance on what resources each application will require after it has been migrated: a measure to verify the performance.

It is important to map the infrastructure resources accurately so that your cost predictions are accurate. While it is generally true that migrating to IaaS can lower costs, you need to consider other factors before migration. For instance, during the transition period, you will be paying for both your on-premise data centre and the cloud.

7 Steps to Include in your Data Migration Plan

Your existing applications may require additional licensing in the cloud, as some vendors have licensing that is not portable between on-premise and a service provider environment.

Check this prior to the migration to ensure that you avoid any licensing surprises after you have migrated. Ensure that your vendor support applies after your migration, as some vendors may have strict requirements. To ensure that there is minimal disruption prior to migrating your production workloads, it is a good idea to test all the network routing and firewall rules. Start by drawing the current state, include all required Open System Interconnection OSI model layers, typically L1, L2, L3 and firewall, packet shaper or proxy devices and include the required bandwidth.Embracing the cloud may be a cost-effective business solution, but moving data from one platform to another can be an intimidating step for technology leaders.

Ensuring smooth integration between the cloud and traditional infrastructure is one of the top challenges for CIOs. Data migrations do involve a certain degree of risk. Downtime and data loss are two critical scenarios to be aware of before starting the process. Given the possible consequences, it is worth having a practical plan in place. Before you start reaping the benefits of cloud computing, you first need to understand the potential migration challenges that may arise.

Only then can you develop a checklist or plan that will ensure minimal downtime and ensure a smooth transition. There are many challenges involved with the decision to move from on-premise architecture to the cloud. Finding a cloud technology provider that can meet your needs is the first one. After that, everything comes down to planning each step. You may also have to take your in-house servers temporarily offline. To minimize any negative consequences, every step should be determined ahead of time.

Cloud Migration Checklist

With that said, you need to remain willing to change the plan or rewrite it as necessary in case something brings your applications and data to risk. A public cloud provides service and infrastructure off-site through the internet.

While public clouds offer the best opportunity for efficiency by sharing resources, it comes with a higher risk of vulnerability and security breaches. Public clouds make the most sense when you need to develop and test application code, collaboratively working on projects, or you need incremental capacity.

A private cloud provides services and infrastructure on a private network. The allure of a private cloud is the complete control over security and your system. Private clouds are ideal when your security is of the utmost importance. Especially if the information stored contains sensitive data. They are also the best cloud choice if your company is in an industry that must adhere to stringent compliance or security measures.

The drawback, of course, is the challenge of managing different platforms and tracking multiple security infrastructures. A hybrid cloud is the best option for you if your business is using a SaaS application but wants to have the comfort of upgraded security. Of course, you should not forget your employees when coming up with a cloud migration project plan. There are psychological barriers that employees must work through.

Be prepared to spend some time teaching them about how the new infrastructure will work and assure them they will not notice much of a difference. Not everyone trusts the cloud, particularly those who are used to physical storage drives and everything that they entail. They — not the actual cloud service that you use — might be one of your most substantial migration challenges. Other factors that go into a successful cloud migration roadmap are testing, runtime environments, and integration points.

Such scenarios can have a severe impact on your business and are a crucial reason to test everything. A good cloud migration plan considers all of these things. From cost management and employee productivity to operating system stability and database security. Yes, your stored data has some security needs, especially when its administration is partly trusted to an outside company. When coming up with and implementing your cloud migration system, remember to take all of these things into account.

Otherwise, you may come across some additional hurdles that will make things tougher or even slow down the entire process.
