If your services have never lived outside an on-premises infrastructure, the prospect of shifting them to the cloud can certainly seem daunting. It may be particularly confusing to know where to start or how to go about planning the migration. Cloud migration tools can come in handy at this point by supporting you and your team as you step into unfamiliar territory.

What is a cloud migration tool?

A cloud migration tool is a program, service, or solution that provides support to companies as they transfer their applications and data from an on-premises environment to the cloud infrastructure or between cloud environments. These tools can assist with all parts of the process, from planning the shift to carrying it out.

It is important to acknowledge that each company’s business goals and applications are different, so there is no one-size-fits-all approach to cloud migration. In a similar vein, there is no perfect tool or combination of the right tools - just the one that is best suited for your needs.

In this guide, we discuss some questions to ask yourself when choosing tools and give you cloud migration tool recommendations to consider for your migration journey.

Choosing the right tools

Cloud migration tools can provide end-to-end support or target certain phases of the migration process like the plan or the execution. Although the idea of the ultimate tool is a myth, the following are a few considerations you can reflect on to determine which tools might be most appropriate for you.

What do you need from the tools?

The first step is to identify the support you are seeking from the tools. Do you need a tool that takes care of your entire migration journey, or do you need assistance with a particular aspect of it?

For the cloud migration tools that claim to provide extensive support across the various phases of the migration journey, check to make sure they do provide that level of assistance. Right from the planning stage to the execution of the migration and offering help post-migration, these are all usually covered by such tools. An especially valuable offering is consultations or prompt and thorough customer support. This is because your team is likely new to the cloud ecosystem and may have questions or apprehensions.

For tools that do not claim to offer direct support across these stages of the process, make sure you are clear about their role in your migration journey. They will also be able to offer consulting services in case you need additional assistance.

Once you have clarity on your requirements, you can begin to conduct research on different tools and figure out which ones are likely to best align with your needs. This will also help you determine whether free versions of certain tools will suffice or if you need the added features that come with paid subscription or solution-based models.

What needs to be migrated?

Oftentimes, when planning a cloud migration, it is a good idea to assess your existing services to determine whether all of them need to be migrated. It is not always the case that the entire infrastructure needs to be transferred to the cloud as some services may no longer be in use or will need to be completely rebuilt as cloud-native services post-migration. While you choose services for server migration, be careful to transfer all important services and applications to minimize data loss. To avoid needless expenditure and wasteful usage of resources, make sure that you have visibility of all your services and their dependencies. Manually doing so can be tedious, so we recommend using a tool that offers this feature.

Are the tools compatible with your target cloud environment?

This is a given, but your tools must be compatible with the cloud environment that you wish to move your infrastructure to. Some tools, especially those with end-to-end assistance, may only let you migrate to their own cloud environments. If that does not align with your goals, look into alternatives.

What kind of insights do you need?

Some tools offer recommendations for your migration plan based on the state of your on-premises infrastructure. Some also display comparisons of performance metrics pre and post-migration. Read on to learn about the 12 best tools on the market.

12 tools to consider

Cortex

Cortex’s contribution to your cloud migration journey is manifold. Our fundamental thesis is that increased visibility into your services and internal workings encourages teams to produce better work, i.e., only when you are aware of your existing conditions can you make meaningful changes to them.

To undertake any migration project, it is important to know what your existing infrastructure and data look like, including service performance, the interactions between various services as well as the dependencies of each. The service catalog centralizes this information into a single platform and lets you visualize it. Any questions that your team has about service ownership, SLOs, or documentation, for example, can be answered by glancing at this dashboard. Cortex integrates with your identity provider to keep the latest ownership information on file. Having easy access to this information also facilitates resolving any errors and minimizing downtime.

The scaffolder is another helpful tool that allows you to build service templates to make it easier to make similar services and standardize your infrastructure. This is especially useful when refactoring services during the migration process. You can create templates that incorporate certain standards required for cloud compatibility, for instance.

Finally, Cortex’s scorecards let you set and enforce best practices across teams without any complexity. You can specify scorecards for the transition to the cloud. These let you keep track of how the migrations are faring for various services. You do not need to run manual checks or search for vulnerabilities for hours on end. The scorecards automate monitoring and deliver visibility to your team as they work on development tasks.

Turbonomic operates on a demand-based migration model. It uses demand-related data to understand the expectations to be met by the workloads when they are being migrated. Doing so does away with the possibility of your workloads using more or fewer resources than they require. It also gives you insights into which of your services can be repurposed or retired. Resource utilization can be very expensive, and this is a way to save costs before you migrate.

Understanding these metrics and matching your workloads with templates available in your destination cloud environments can be a time-consuming and laborious process. Turbonomic automates these tasks for you. Its user interface facilitates the job of selecting and migrating your on-premises servers to the public cloud. You can choose your cloud provider as well as specify the regions you want to migrate to.

Finally, Turbonomic presents you with a resource summary that outlines the cloud pricing, savings, and any changes in the number of active hosts, storage devices, and virtual machines. With information about which, if any, of your VMs are undersized or oversized, you can choose to scale them up or down. Resource allocation is an important consideration, and we recommend using the opportunity provided by the cloud migration process to reflect on your current practices and make changes as you see fit.

AWS Server Migration Services


One of the largest cloud service providers, Amazon Web Services (AWS), has an all-encompassing portfolio of cloud migration services that facilitate the movement of your on-premises infrastructure and data to the cloud. It divides the migration journey into three phases: assessment, mobilization, and migration and modernization. Each of these phases can be supported with multiple tools, depending on your team and application’s needs.

The assessment phase is for evaluating your team’s and application’s readiness to work in a cloud environment. AWS tools map out your existing on-premises workloads and give a cost estimate for running them on the cloud. The Migration Evaluator provides ongoing recommendations for rightsizing and AWS’s Migration Hub is a tool that centralizes information about the progress made by each application in its migration journey.

In the second phase, your team can create and refine your migration plan, as well as build a baseline environment and learn cloud skills. Here you can determine which migration strategies are most relevant to your services and business goals. In the final stage, you can execute these. The AWS Application Migration Service is ideal for automating lift and shift operations. The Migration Hub Refactor Space helps you take care of any refactoring tasks to be carried out. Additionally, AWS has various provisions for database and data transfers to the cloud, depending on the nature of the data.

AWS has a service or a combination thereof for virtually any use case under the sun. It provides end-to-end support such that your migration to the cloud is seamless and hassle-free. To this end, it also offers certification and training for teams.

Terraform

HashiCorp’s Terraform presents automated infrastructure and policy as code solutions to migrate your on-premises workloads to the cloud. You can define your resources in Terraform configuration files which are human-readable.

When done manually, infrastructure provisioning is slow and lacks scalability. It is also more susceptible to errors. Terraform proposes automation to address these concerns. When codified, a workflow can be kept consistent, which simplifies infrastructure management.

Using a three-step process of writing configuration files, making a plan for the infrastructure based on your current infrastructure and configurations, and applying or executing the plan keeping dependencies in mind.

Terraform takes an immutable infrastructure approach, which prevents you from editing existing infrastructure and configurations. Instead, you must create a new version with the changes you would like to see and only delete the first version if it succeeds. This approach helps you avoid irreversible errors and simplifies the process of making changes to your services. Terraform also maintains a state file, which it uses to track your original infrastructure and identify the modifications to be made to it.

Terraform also automates the process by asking you to write your ideal version of the infrastructure in the configuration files, as opposed to a step-by-step breakdown. It takes charge of the actual logic to execute the changes and arrive at the finished product by itself.

Terraform’s utility is especially visible when you are refactoring or rearchitecting your services for the cloud. Each team can independently write their configuration files and develop workflows that can then be shared across teams. This results in stronger collaboration and increased transparency across the board. The level of automation offered by Terraform also does wonders for your team by freeing up energy and time that can be focused on other tasks. Errors and delays are also few and far between.

Rclone

For fans of DIY or manual processes, rclone is a powerful alternative to migrate data to the cloud. It is a command-line program that allows you to migrate, manage, and analyze data in cloud storage, with support from over 40 cloud storage providers. Praised as “the Swiss army knife of cloud storage,” rclone is inspired by the command line utility rsync.


Rclone is an open-source program that operates at the level of whole files or objects. Although most popular with Linux users, rclone is also used on Windows and Mac. You can continue to use rclone even after migration from on-premises to the cloud as it supports inter-cloud migration too. 

Third-party developers continue to build upon it using the command line or API to offer additional innovative solutions. If you are looking to dip your toes into this program, you are guaranteed support from the rclone user community.

Make the tools work for you

Cloud adoption is known to be a labor and cost-intensive project that necessitates meticulous planning each step of the way. Depending on the migration strategy you adopt - from a simple lift and shift to a more involved refactoring process - this may have earlier seemed complicated or next to impossible. 

The advent of cloud migration tools has changed that by simplifying the entire process to the extent that you only need to be concerned with the key steps and challenges of the transition. The tools will handle the rest, often by automating straightforward processes. Note that relying on tools to assist you is not a compromise but a smart decision. Knowing how and at what point you could benefit from external help is an advantage, as it saves you both money and time, in addition to allowing your team to focus on other critical tasks.

The cloud migration journey is not without hurdles, so we recommend reflecting on your requirements and the specific needs of your services to make informed decisions about the tools that will best meet them. Pick your tools and get started as soon as you can to reap the benefits of the cloud.
