A cloud migration strategy is the plan an organization makes to move its data and applications from an on-premises architecture to the cloud. Not all workloads benefit from running on cloud-based infrastructure, so it is important to validate the most efficient way to prioritize and migrate applications before going live. Many organizations start migrating to the cloud without devoting sufficient time and attention to their strategy.
Both these features are difficult to achieve with an on-premise setup.
The complete refactoring took them years but proved the best approach for them. Today, it has 8 times as many members as in 2008 and is a global OTT platform with a presence in 130 countries. It followed the ‘lift, tinker, and shift’ approach to move the microservices to Docker containers powered by Kubernetes. As a result, it reduced the instance hours for the engineers and made it cost-effective. Cloud computing allows organizations to almost instantaneously add or take away resources as needed or to match demand. Elasticity is the ability to quickly expand or decrease computer processing, memory, and storage resources to meet changing demands without worrying about cloud capacity planning.
Complexity — Public cloud is generally easier to manage, but it can get complex . Your talent needs to be capable of managing your cloud and understand the effort needed for a successful migration. Movere — This SaaS platform was acquired by Microsoft in 2019. It’s a discovery solution that increases business intelligence to see and control environments across. Repurchasing — Got a legacy application that won’t easily move to the cloud?
Depending on the cloud provider you pick, there are different considerations to keep in mind and different migration strategies. Latency and performance—on-premise applications might suffer from latency or performance issues after migration, because they were not optimized or modified to suit the cloud environment. Easier compliance and security management—since applications aren’t changing security and compliance properties also stay largely the same and just need to be mapped to new resources. Reverse cloud migrations — This migration away from the cloud to an on-site data center is also called cloud repatriation, de-clouding, or unclouding.

Changing the way the program interacts with the database to benefit from automation and an elastic database infrastructure. In the following sections we’ll explain the first three strategies in depth, with their pros and cons. When expanded it provides a list of search options that will switch the search inputs to match the current selection. Stakeholder support — You want leadership committed to the long game when it comes to cloud. This is where forming a Cloud Center of Excellence really pays off.
When it comes to managing the challenges of cloud migration, internal IT teams are constrained by their skill sets and resources. If your IT personnel lacks the necessary credentials and you work in a sector with strict requirements for data security compliance, your company may be at risk. One of the most important aspects of successful cloud migration is security. It is critical to protect data and workloads while transferring them to the cloud because these assets can be vulnerable if not managed carefully.
Replicating the environment as is, is the most expeditious path. Upgrading while migrating lengthens the migration and causes delays and frustration. The only time it is advised to upgrade prior to a migration is any applications or Operating Systems are out of support. Then it’s advised to upgrade first, verify function of the upgraded software and then perform the migration. Repurchasing entails completely replacing your legacy software with a cloud application purchased from a cloud service provider. This strategy is best for companies with an adaptable culture that can embrace rapid technological upgrades.
Since workloads on the cloud continuously evolve, it may require improving the foundation. Training is instrumental in empowering your staff to better adapt to the new ways and facilitate smoother migration. To bring more clarity and transparency, you can establish a clear set of roles, responsibilities, and protocols for reporting and management. Not all IT professionals are familiar with cloud infrastructure and may need to be educated on the new technology. In some cases, cloud adoption may also require introducing new IT management roles or transforming business operations. Despite these numerous benefits, you may not be able to fully avail features like ephemeral compute and autoscaling.
Colin A.B. Fernandes serves as Sumo Logic's director of product marketing, EMEA, and is responsible for growing the business in the EMEA region. Keeping applications and their data safe is a vital responsibility at all times. When migrating to the cloud, of all the things that can go wrong, or simply be neglected, security is at the top of the list. In a recent study, 81% of respondents identified cloud security as the top challenge when migrating workloads to the cloud. A cloud adoption framework provides a baseline for organizations to use when mapping out their cloud migration journey.
For this reason, it is essential to communicate with employees about the changes in advance. It is also reassuring to communicate the tasks and changes that will affect each person so that when it is time for the migration, they will already be prepared. A step-by-step plan categorized in each of the 6 R’s explained earlier can go a long way. All you need to do is start small with the least critical workloads and move forward confidently. Consider both business goals and technical aspects while developing your migration plan. What Spotify did was it migrated 1200+ services and 20,000 data jobs to the Google Cloud without causing any ripples in the streaming experience.
A physical transfer may be advisable when transferring highly confidential data. Network connections are less secure than physical media, potentially putting data at risk. To understand how to design and implement secure cloud architectures, check out this white paper. Keep in mind that temporary servers frequently cannot handle high user loads.
And encrypt any data before transferring it to transfer devices offered by vendors. Multi-factor authentication should guard all cloud-hosted data. Access should only be available to users with applicable privileges. Ensure data is available to relevant staff and access is limited to those with appropriate privileges. Model workloads to ensure apps can operate together without additional friction. Decide which data needs additional protection from end-to-end encryption.
If you cannot foresee yourself using the benefits cloud providers offer, then don’t. On premise deployment has been the solution for ages, and there is no need to push onto new technology if it offers you no benefits. Refactoring is much more complex than other cloud migration approaches, because it requires application code changes, and needs to be tested carefully to avoid regressions cloud data migration in functionality. You also need to ensure that the application is built for better resource utilization in the cloud, to avoid incurring high costs. Lift-and-shift can be used for simple, low-impact workloads, particularly by organizations that are still far from cloud maturity. If your current setup includes loads of virtual machines, it’s relatively straightforward.
Once the testing is done, the KPIs defined during the goal-setting phase must be used to measure short- and long-term success. You need to assess the state of your current business infrastructure to fully understand how it works and how migrating data and applications to the cloud will affect it. Adopting cloud technology might require changes in your entire business.
RackWare has a powerful, secure, highly automated solution to migrate your workloads into Azure, AWS, IBM Cloud, Oracle Cloud, and GCP. Our solution is proven in the most difficult environments for all applications. Retiring is when a company decides that part of their IT architecture doesn’t need a cloud analog (or it isn’t worth the migration effort), so they decommission the application.
Move these assets with care after testing the process with non-critical assets. For example, you may create a disaster recovery server on the cloud to store core data in the event of cyber-attacks or natural disasters. In that case, planning should focus on security, data transfer, and resilience. Companies must assess which apps to transition and which to either retain or retire.
Timely problem resolutions are critical to successful cloud migration. You can also expect re-strategizing based on the events that unfold. Getting existing applications to communicate properly with newer cloud environments can be challenging.
