It’s one of the quickest and easiest cloud migration strategies that moves data without code-level changes. Embracing the power of the cloud has become inevitable to succeed in today’s digital era, especially when organizations are increasingly migrating their applications to the cloud to drive growth. According to Gartner, the worldwide spending on public-cloud services is forecast to grow up to $304.9 billion in 2021, up from $257.5 billion in 2020.
This is also a good choice for legacy applications not easily virtualized or migrated in other ways. Instant scalability can be realized by migrating to public cloud providers, enabling enterprises to meet changing demand at will, whether fluctuations are caused by seasonality, business growth, or another spike. Cost savings can be considerable since resources are only paid for while in use. The lift-and-shift model, also sometimes referred to as rehosting, is simply taking the applications from the onsite data centers and moving them into the cloud without changing anything.
While migrating to the cloud there might be some crucial old/legacy version applications that may not be compatible with the cloud. That’s why you need to implement a phased approach for your cloud migration process. You need to have visibility into the application migration process and cloud resources being used, which can be achieved by using application performance monitoring tools. These provide application-level visibility and can be used to monitor application performance and cloud services, identify application dependencies, and track application deployments.

The following steps will help you run a smooth cloud migration process and take full advantage of the cloud’s benefits. First, it’s important to assess which workloads are best suited for the cloud. Not all applications can or should be migrated, so it’s critical to identify those that will benefit most from the move. Once you’ve determined which workloads will be moving to the cloud, the next step is to select a suitable provider. There are a number of factors that need to be considered when making this decision, such as cost, security, and performance.
- Laws are regularly passed, and those that already exist are frequently modified.
- It should also be noted that not all applications need to be moved to the cloud, in which case it’s perfectly fine to keep them on-premises, provided they are still meeting business needs and are well-maintained.
- This is also a good choice for legacy applications not easily virtualized or migrated in other ways.
- Cloud providers offer managed services that lower your operational overhead and simplify maintenance tasks such as upgrades.
- Done right, the efficiencies of the cloud can help businesses weather a period of slow growth and tightening budgets.
- One customer that leveraged Cloud Volumes ONTAP to make their Google Cloud migration a success was a Fortune-500 ranked global healthcare services and products company.
The cloud also makes it easy to scale applications and services up or down as needed, which can help organizations save money on resources that are not being used. Companies that want to migrate to the cloud should consider which migration strategy is right for them. The guarantee that your data will remain accessible is critical to supporting high priority workloads and applications and is the reason many move to the cloud in the first place. Organizations often choose to adopt new cloud-based systems and services to take advantage of the capabilities offered by cloud service providers . Learn how organizations adopt cloud technology, the dangers of cloud adoption, and how to gear your organization for success. You’ll also need to find a way to synchronize changes that are made to the source data while the migration is ongoing.

She acts as a Product Leader, covering the ongoing AI agile development processes and operationalizing AI throughout the business. The main disadvantage of repurchasing, though, is that it can be expensive, especially if you need to purchase multiple applications. In addition, it can take time to find the right application and get it up and running. The cloud offers a shared responsibility model and workloads should be secured using a zero-trust approach by utilizing stateless transactions where possible. Live MigrationThe ability to move a live running VM between your on-premises environment and your VMware Cloud on AWS SDDC is almost table stakes when talking about a hybrid cloud. RelocatingPerhaps the simplest form of migration, this strategy refers to moving VMware VMs from on-premises hardware to VMC.
Ideally, businesses start with the less-critical components and move the critical ones only with the right support system in place. New applications must be designed, migrated, and tested using the chosen strategy. Once the migration of all necessary components is complete, the strategy should also specify how decommissioning of the older system will take place.
The extent to which these are addressed can lead to some aspects of a replatform. The AWS Migration Hub also helps you to right-size your compute resources, based on the on-prem usage, to lower your cloud costs. When you migrate an application then you also inherit the operating system, possibly undocumented configurations, and “non-cloud” people and process with it. These are non-cloud, so it has to be clearly understood that no magic will cloud data migration happen in terms of transforming people and processes through rehosting. An anti-pattern is to rehost a suite of applications without committing to the subsequent time and effort required to modernise those applications, to realise the benefits of the cloud. The available staff are familiar with virtualisation and infrastructure-as-a-service so rehosting matches their skill sets, unlike replatforming and refactoring which demand more skills.
It will lead you to the choice of the most suitable cloud migration strategy for your company.

The relocate strategy doesn’t require that you purchase new hardware, rewrite applications, or modify your existing operation. During relocation, the application continues to serve users, which minimizes disruption and downtime. Relocate is the quickest way to migrate and operate your workload in the cloud because it does not impact the overall architecture of your application.
With the end goal in place, Spotify revealed that it invested two years in pre-migration mode, essentially preparing a migration strategy and creating a dedicated migration team to execute this documented plan. Its strategy involved a mix of rehosting and rewriting, with individual and channeled focus on its services and data. There’s the cost of IaaS services, https://globalcloudteam.com/ the cost of moving resources, and the cost of training employees for cloud-related usage and administration. There is also the fact that until the migration is completed and tested, both the on-premise and new cloud setup need to run in unison to ensure business continuity. A hybrid setup may also be required in some cases, as mentioned earlier.
We’ve also found that applications are easier to optimize/re-architect once they’re already running in the cloud. Partly because your organization will have developed better skills to do so, and partly because the hard part — migrating the application, data, and traffic — has already been done. You must take their needs into account when implementing new solutions. Consequently, to make the most out of the cloud migration, you need to choose and adjust a coherent strategy. Only then you will know which profits are most important for you and how to make it work in your favour.
Benefits of Moving Business Applications to the Cloud
Also known as brownfield migration, a system conversion transforms your application layer, along with the DB and OS layers. The process may involve extensive changes to the way your landscape is run and managed as well as the landscape itself. Your new, upgraded system will likely have greater automation, and require different competencies than your on-premise legacy system. That may warrant a change to a managed services model, and a new approach to management emphasizing proactive planning. Properly handled, that means more consistent performance, lower cost and less downtime in the future.
The legacy mainframe application can no longer address the demand of the business due to its limitations or is expensive to maintain. You can avoid recoding and re-architecting a custom application by repurchasing a vendor-based SaaS or cloud-based application. For more information, see Best practices for assessing applications to be retired during a migration to the AWS Cloud. You want to reduce the security risks of operating an application that uses an operating system version or components that are no longer supported. It doesn’t require many resources, which helps to scale, and provides long-lasting ROI.
Types of Cloud Migration Strategies
These features are in addition to the standard security practices and protocols that cloud providers offer. Automatic updates, regional isolation, and security definitions are frequently monitored and tested against the latest known security threats. While there are many benefits when moving operations off-site, issues such as stability, costs, and security can arise.

Another consideration to keep in mind is meeting ongoing performance and availability benchmarks to ensure your RPO and RTO objectives should they change. This acceleration is accomplished while also delivering automated data profiling and masking of sensitive data.
Cloud Migration Deployment Methods
Create a PaaS solution, discard code for an existing application, and re-architect the application. It is common for organisations to arrange a security pen-test for the cloud environment. This can often identify security issues that also existed on-prem, as well as new issues in the cloud configuration.
Employees won’t lose working hours due to inclement weather, and critical company data can be accessed safely and securely from remote locations. Switching to the cloud allows businesses to drastically alter their operations and infrastructure to facilitate the current demands without being restricted to quickly depreciating equipment. The power to promptly scale a company’s workload allows it to tailor its resource allocation effectively. The organization needs to ensure that all functionality is replicated by the new system, along with business process flow. Old data must be audited, discarded where appropriate and reformatted to work with the new system. On top of that, there’s the requirement to retrain the team in a new suite of applications, which might function quite differently from the previous application stack.
This strategy allows you to realize the full potential of cloud-native technologies like microservices architecture, serverless, containers, function-as-a-service, and load balancers. For example, you can refactor assets when you move your digital assets from an on-premise monolithic architecture to a fully serverless architecture in the cloud. These refactored applications are scalable, agile, efficient, and return ROI in the long run, even in the most competitive markets. This post outlines 6 different migration strategies we see customers implement to migrate applications to the cloud.
Cloud Migration Challenges
We can assist with the actual migration process, ensuring that your data is moved safely and securely. Re-platforming can be a complex and costly undertaking, so it’s important to carefully consider whether it’s the best option for your needs. In some cases, it may be simpler and more cost-effective to simply re-host the application on a new platform.
If you have huge applications to migrate to the cloud, choose one at a time.
