Planning Your Cloud Migration: A 10-Step Cloud Migration Checklist

After you cut over and go live, perform a post-migration validation of applications, data and network. Troubleshoot failures, service outages, data anomalies or performance hiccups. If you are unable to quickly remediate major issues, minimize impact by instituting a rollback to investigate what went wrong and re-schedule the migration.

Data blocks may be lost or erased, ensure data sensitivity.

Cloud migration process

As such, the cloud migration strategy must also consider the time and capital investment that goes into this training. The central aim of a cloud migration strategy is to minimize downtime and make data available in the new cloud environment. Good vendors should provide services to track code changes and sync all changes across enterprise assets. The bare-metal cloud infrastructure is built with state-of-the-art technology. If a physical machine dies, another one replaces it without affecting your business operations.

On the other hand, by migrating your existing architecture, you’re basically using the cloud as just another data center. For some companies it pays to make better use of the cloud services available — for example, to add scalable functions to your app to improve the experience for a growing segment of users. Some workloads require a hybrid cloud that connects both public and private cloud environments. A hybrid cloud can give you the control of the private cloud for your sensitive, business-critical assets, plus the flexibility and cost savings of the public cloud for your public-facing operations. Surveys indicate that most enterprises are concerned about cloud security issues, and there is confusion regarding responsibility over cloud security.

Enterprises typically choose this strategy when the application is business or mission-critical, but a move to the cloud is necessary. Enterprises choose to repurchase when their legacy system is not compatible with the target cloud environment and business needs require a change. Typically, re-platforming is performed to ensure the asset performs optimally when placed in the new environment or adding new features. Enterprises choose re-platforming because it is often a cost-effective strategy. However, if the scope changes during the implementation, overhead might accumulate due to excessive modifications. Move your customers gradually and test the working at every move.

Cloud migration process

Adopting a cloud migration strategy aids in locating and carrying out the on-premises to cloud conversion that is the quickest, least disruptive, and least expensive. Organizations worldwide spent close to $125 billion on cloud services in 2020. And for the year 2021, global cloud infrastructure spending specifically in IT industry totaled $73.9 billion (up by 8.8% over 2020). To benefit from running programs without maintaining and updating infrastructure, choose SaaS.

Security and compliance risks

Monthly subscriptions are charged based on the exact number of licensed users on the product each month. Annual subscriptions are charged based on the user tier you fall into, and are offered at a reduced rate. Keep these questions in the back of your mind throughout the next phase to help you make decisions regarding planning and strategy.

The majority even offer autoscaling – programmatic resource optimization, which automatically upgrades or downgrades resources according to your app’s needs. Thus, your cloud provider strikes the balance within resource optimization – enough resources to scale with increasing demand, but not by sacrificing your operations with unnecessary costs. Building your app on multiple public cloud providers and pick-and-choose the comparative strengths of each one.

Cloud migration process

Your hosting provider will be adaptable enough to accommodate these needs as they evolve over time. Migrating from on-premise to the cloud requires careful preparations on technical and business ends. Compliance with the basic checklist and experienced professionals on your side will ensure a smooth transition. Apply automated migration tools where it’s possible and appropriate after finishing with backups. Although you’ve already done a lot to prevent accidental data losses, you may want to play it safe with critical data.

To reap the benefits from cloud applications, such as flexibility, resilience, agility, and open new opportunities for the business, organizations move parts or their entire IT resources to the cloud. Bear in mind that while cloud vendors https://globalcloudteam.com/ provide access to a rich set of metrics for responding to changes in your cloud environment, these metrics are not usually in the context of the overall application. You’ll need a separate monitoring solution for that level of visibility.

A list of assets and interdependencies is the starting point to decide how and when each piece of the system moves. It is highly unlikely that an organization can just forklift the entire infrastructure as a whole and place it onto the cloud. cloud data migration This actually allows for the large expense to be amortized over the years, as opposed to monthly expenditure of relatively small amounts of money. The mode of payment depends on the company’s financial model and internal policies.

Choose the Best Provider

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. The larger or more complex your current infrastructure, the harder these challenges are to overcome. It might be that some of your applications should stay in house — for example, apps that manage internal processes or have special sensitivity to the organization. Don’t be afraid to revisit cloud computing at a later date. You should only migrate what makes sense to the business.

Formulating a robust cloud migration strategy is the first step toward migration. As of today, most organizations already have at least one cloud component in their architecture. But according to Flexera’s report, on average, businesses estimate that they waste 30% of their spending on the cloud.

Below you’ll find two separate processes that illustrate the organization of an actual migration. A helpful exercise would be to use the first process to ask yourself all the relevant questions then insert those answers into the structure presented by the second method (the Step-by-Step Method). Just as the name implies, there is no big architectural change to the servers and applications in this situation. They are simply taken from on-premises and moved to the same type of system on the cloud . Organizations that are just starting their migration journey will often use the lift-and-shift strategy. WhenLiquidPowerneeded to become a standalone company within Berkshire Hathaway, it turned to cloud migration in order to modernize its systems and processes without disrupting services to customers.

Choose the Right Cloud Environment

It holds our application and then drops it into our new hosting platform without changing the architecture and code of the app. Also, it is a general way for enterprises unfamiliar with cloud computing, who profit from the deployment speed without having to waste money or time on planning for enlargement. A solid strategy won’t completely eliminate all the hurdles and potential problems with a cloud migration. Sometimes IT leaders discover that their applications don’t work as well in the cloud as they did on premises.

After you’ve assessed your apps and determined which ones you’ll need in Cloud, reference these pages for Jira and Confluence apps to determine what migration paths are available today. If you have questions on app migrations beyond what’s available in the documentation, we recommend reaching out to the app vendor directly. Assess which data to migrate to Cloud and which data and/or inactivate users to leave behind on your Server instance. Migrate only necessary data and users in a single downtime window. Verifying your domain will secure ownership of your company’s domain and claim all users’ accounts with that same domain. Choose a method and follow the steps onhow to verify a domain for your organization.

Challenges of cloud migration

Cloud migration is the process of moving data, applications, and workloads from on-premises or legacy systems to access via the internet. Selecting the best cloud provider can mean the difference between a successful migration and a catastrophic failure. Businesses need to pick a provider that works with you not only during the Cloud migration process but also afterwards for guaranteed smooth transition. The ideal provider should have proven experience in Cloud migration, management, and expert support. They should offer multiple cloud models and service level agreements that cover various areas of deployment and hosting including uptime, performance, and data availability. If issues arise, customer support should be available 24x7x365 to troubleshoot or answer questions quickly.

Planning for disaster, as well as normal operations, can help reduce any overhead that might accumulate when there is no adequate plan in place. When enterprise assets are already located in the cloud, and the enterprise shifts the information to a different cloud, the process is called cloud-to-cloud migration. Enterprises can also perform a reverse cloud migration, and shift assets from the cloud to a local data center. First, establish and foster careful communication and collaboration between IT and workload owners. IT and business leaders must agree about the goals and intended benefits of a cloud migration. Technology staff must know the requirements and expectations of the stakeholders in order to create suitable cloud infrastructures for a workload.

Finalize which assets are moving and when

AWS has many services and tools for managing and monitoring cloud migration. In rehosting strategy, your applications are transferred to the AWS Cloud as it is, and no modification is made. Your application stack is simply migrated from your local server to the AWS Cloud. “Drop” and “Shop”, is an analogies used for repurchasing. This strategy entails changing your application with a new one. The software product should offer greater commercial value than the current one.

In other cases, it might be more beneficial to change an application’s code or architecture. This process is known as refactoring an application or rearchitecting it. This can be done in advance of a cloud migration, or retroactively once it is clear that a lift and shift has reduced an application’s performance.

Public cloud users generally consume these services in a pay-per-use model. A business can choose to extensively modify the workload’s code to use more of the cloud’s native services. This requires a clear and detailed understanding of the cloud provider’s resources, services and infrastructure.

Cloud migrations can be complex and contain a lot of moving parts. One of the most complex aspects of a migration, especially in a large enterprise, is moving and synchronizing large volumes of data. Migrating to the cloud can improve performance and end-user experience. Applications and websites hosted in the cloud can easily scale to serve more users or higher throughput, and can run in geographical locations near to end-users, to reduce network latency. Migrating to the cloud is not a decision that should be taken lightly – you need to carefully think about all aspects of your application and IT landscape before making the switch.

Thus, it is essential to establish such a role within your organization to ensure your migration project’s success. Software as a service provides a ready-made application, which alleviates the need for a business to deploy its own workload in the cloud. The SaaS provider handles all of the workload’s development and maintenance. Common SaaS offerings include email and productivity applications, as well as financial and HR workloads. This approach modifies a relatively small portion of the underlying codebase to optimize a workload for improved reliability or performance in the public cloud.
