10 Best AWS Cloud Migration Tools and Services
What is an AWS migration?
An AWS cloud migration is the process of moving your digital business operations to Amazon’s leading cloud computing platform. This process involves migrating data, applications, and IT processes from one data center to another.
The originating data center could be one that was located at an on-premises location, or perhaps located on another cloud provider, such as Azure or the Google Cloud Platform.
This process may require significant preparation and expertise to migrate the technology effectively, but well worth the effort for subsequent cost-saving and flexibility benefits.

Why migrate to the AWS cloud?
Migrating to the cloud has become the new normal as companies of all sizes are realizing the significant benefits that the cloud has to offer. AWS has the most migration-focused services out of any cloud vendor, enabling you to make smooth and effortless migrations right when you need.
AWS has dedicated migration experts who are available at every stage of your transition to help make the process simple and secure. Here’s how your organization can benefit from workloads in the cloud.
Cloud computing enables you to scale up to support greater workloads as demand increases, making it far easier than on-premises infrastructure. The downside of on-site servers is that you are required to purchase and set up additional servers, licenses, and equipment - whereas, with cloud computing, you just pay as you go.
Amazon delivers 3X more features per year compared to other vendors and is keen on providing you with the right resources, whether a new trend has emerged or demand is increasing.
Migrating to the cloud will significantly reduce the amount you spend on IT operations because the cloud provider handles the maintenance and upgrades. With AWS, you can scale your resources according to demand so that you only pay for what you need.
On AWS, the average company saves roughly 31% on infrastructure costs alone.
The cloud enables you to connect to servers that are close to your customers. If you’re in Arizona and you leverage regions in Oregon where some of your customers are located, the data won’t have to travel as far to reach the users, reducing latency.
With the cloud, employees or customers can access the cloud services and data from anywhere. This makes it easier for businesses to quickly expand their operations to new locations, offer their services to a global audience, and hire remote employees.
Top 10 AWS Migration Services
AWS has an extensive ecosystem of resources designed to simplify and accelerate each step of the migration process. There are 3 phases during the migration process: Assess, Mobilize, and Migration - Modernize.

AWS Cloud Migration Strategies
AWS refers to their 6 migration strategies as the “6 R’s”. These 6 R’s are the primary strategies for migrating your data over to the AWS cloud.
Re-host (Lift and shift)
Re-host is the process of moving applications from their old existing infrastructure to the cloud without any changes to the code. This method is the simplest approach to migrating your application to the cloud.
Much of the re-hosting can be done via automated tools such as AWS VM import/export. Once the application is hosted on the cloud, you will be able to optimize and re-architect much simpler.
Re-platform (Lift, tinker, and shift)
Similar to re-hosting, re-platform is the process of migrating your application to the cloud but with a few adjustments during the process. These small modifications could include something such as altering the way your application interacts with your database so that you can benefit from automation and a higher-performing database.
During this process, you might also consider integrating new features that will enable better scaling and allow your application to benefit from the reserved resources of your environment.
Re-factor / Re-architect
Re-factor or re-architecting readdresses the architecture and development of your application by integration with cloud native features. Organizations typically choose this model because their current environment cannot support demand, therefore, they need to re-architect, adding necessary features to scale and boost performance.
If you’re interested in migrating your monolithic architecture to a server-less architecture, this paradigm might be the best fit. Refactoring is a time-consuming and expensive process but will enable greater manageability over your resources and pay off as your business begins to scale.
Re-purchasing involves moving from a perpetual license to a company that employs a software-as-a-service model, such as Salesforce’s CRM, Jira’s task tracking software, or Drupal’s CMS.
Retiring is the process of moving applications that are no longer being utilized or are in low demand. You might find out that simply removing an application will save you more money on resources and hosting than you’re generating from the software.
By removing these unnecessary applications, you drive your team’s attention to the applications that matter, while reducing the resources required to maintain a proper security posture.
Have an application that requires extensive facelift before a major migration? Put these applications on the back-burner and follow up at a later point in time once you have the other, more important applications migrated.
AWS Cloud Deployment Models
In addition to these 5 AWS cloud migration strategies, your business will need to factor in how the deployment will look once the migration is complete. There are 3 main deployment models that you can use on AWS.
A cloud-based application is an application that is fully deployed and operates all of its elements in the cloud. Cloud applications are either built in the cloud or are migrated from existing infrastructure.
The data from cloud or public clouds are created and stored on third-party servers. The infrastructure belongs to the cloud service provider, which in this case is AWS. People prefer this option for the flexibility, accessibility, and low maintenance of cloud computing services in addition to many free and affordable service options.
Also known as “Private Cloud”, on-premises enables you to provide dedicated resources. The servers are generally located at the company’s physical location and are maintained on a designated private network and are intended to be used by the company itself.
A private cloud deployment model gives you more flexibility when customizing the infrastructure exactly to your requirements. Because the servers are hosted on-prem, you benefit from higher security, privacy, and reliability, as only authorized personnel can access the resources.
A hybrid cloud deployment model involves connecting on-premises and cloud-based resources to operate in synchronization. This option gives people the flexibility to leverage the best features that physical servers have to offer while making use of the cloud’s on-demand resources.

Cloud computing does offer many benefits to users who are just starting to put together applications and solutions. Having an existing solution will not preclude an organization from being able to take advantage of the cloud. Migrating those solutions to a cloud environment can prove to be tricky for users who haven’t planned in advance.
DevOps is a composition of best practices, principles, and company cultural concepts that are tailored to improve coordination in either development or IT teams in an organization. These standards help to streamline and automate the delivery cycle and allow teams to deploy applications sooner. In the case of arising issues, teams can respond faster and develop fixes sooner.
