Application Migration is the process of moving software programs from one computing environment to another. This can include migrating apps from one data centre to another, from a public cloud to a private cloud, or from an on-premises server at a firm to a cloud provider’s environment.

What is Application Migration?
Application Migration is the process of migrating an application from an on-site enterprise server to an AWS environment to take advantage of benefits such as elasticity, disaster recovery, improved management of expenses, and many others. Businesses transfer applications to the cloud to benefit from cost reductions, flexible expansion, and the capacity to update software quickly in reaction to demand changes.
Because apps are frequently built for a single cloud platform and optimized to run on specific operating systems in specific network architectures, moving them to a different environment may provide a number of challenges. Applications running on bare metal hardware are often more difficult to migrate from virtualized or service-based architectures.
6 Phases of Application Migration
The 6 essential phases of Application Migration are:
- Cloud Assessment Phase: A stage in which your business assesses its resources and IT environment to see if it can make the switch to the cloud.
- Proof of Concept Phase: This proof of concept typically entails a small, undeveloped, or generally simplistic version of the desired end result.
- Data Migration Phase: Moving data from one location, one format, or one application to another is referred to as data migration.
- Application Migration Phase: Moving software programs from one computing environment to another is referred to as application migration.
- Leverage the Cloud Phase: Cloud technology helps businesses to provide business value while leveraging highly accessible cloud infrastructure without worrying about supporting physical infrastructure.
- Optimization Phase: The business process improvement cycle includes steps called optimization phases, which can be used to research and plan upcoming organizational changes
Types of AWS Migration Services
- Application Discovery Service: Application Discovery Service Collects configuration, usage, and behavioral data from on-premise servers and helps to plan the migration to the AWS cloud.
There are 2 types of Application Discovery Services: AWS Discovery Connector & AWS Discovery Agent
- AWS Migration Hub: It helps to track the progress of the application by providing a single location dashboard. It allows you to choose the AWS and partner migration tools and provides fundamental matrices and progress for each application.
- Server Migration Services (SMS): It automates an incremental replication of a live Provide end-to-end server and provides an end-to-end server migration process for on-premise VMS. It also provides UI to track the progress of the server.
- Database Migration Service (DMS): A web service used to migrate data from on-premise databases, DB instances, or databases running on an Amazon Elastic Compute Cloud (Amazon EC2) instance.
AWS Migration Hub helps to keep track of the progress of DB Migrations and provides key metrics.
Real-Time AWS Application, Data & Database Migration Project
Are you ready to level up your expertise? Our job-oriented program introduces a hands-on project, focusing on migrating applications, data, and databases to AWS using the AWS Application Migration Service. Tailored for Solutions Architects, SysOps, ServerOps, InfraOps, and Migration specialists, this real-time project is a gateway to mastering cloud migration.
What Makes Our Project Unique?
- Real-Life Simulation: Our project replicates a real-world scenario where a customer migrates their workload from on-premise to AWS. Following the Migration Acceleration Program (MAP) best practices, the project covers the Assessment, Mobilization, and Migration phases.
- Practical Learning: You will not only acquire theoretical knowledge but engage in practical exercises simulating a customer’s environment. This includes configuring AWS EC2 servers, setting up networks, DNS servers, pre-installed applications, and a bastion host.
- Step-by-Step Approach: The project adopts a step-by-step approach, encompassing Re-Host and Re-Platform methodologies. Participants navigate through AWS Application Discovery Service, AWS Migration Hub, AWS Migration Service, and AWS Database Migration Service for a comprehensive understanding.
What to Start Looking For:
- Hands-On Experience: You will explore the lab environment, gaining hands-on experience in connecting to the lab and bastion host. The architectural reference provides a clear guide for setting up the emulated on-premise environment.
- AWS Application Discovery Service: Learn server and application discovery using AWS Application Discovery Service. Tasks include creating ADS credentials, enabling Athena integration, installing ADS agents, and browsing discovered data.
- Migration with MGN: Understand the Migration Life Cycle with AWS MGN. From configuring AWS MGN Service to launching test instances, shutting down the source environment, and validating applications, participants experience the entire migration journey.
- Database Migration with DMS: Delve into AWS Database Migration Services (DMS) to create Aurora target databases, configure DMS, specify source and target endpoints, and monitor migration tasks. The project covers shutting down source servers and updating DNS for a seamless transition.
By the end, you’ll comprehend migration intricacies and possess practical skills to migrate applications, data, and databases to AWS. Don’t miss this opportunity to advance your career in the dynamic realm of cloud computing!
Frequently Asked Questions
How long does it take to migrate to AWS?
The minimum time required to take over the network connection at 80% utilization is roughly 28 days if you have a Gigabit Ethernet connection (1 Gbps) to the internet and 100 TB of data to transfer to AWS.
What are the 3 main phases of a cloud migration?
AWS cloud migration can be broken down into three phases: Pre-Migration, Migration, and Post-Migration.
What is cutover in cloud migration?
Cutover enables you to plan and execute your Cloud migration collaboratively while maintaining visibility of current status throughout. Cutover unifies enterprise human and machine orchestration, connecting to technical enterprise tools for complete visibility.
How does AWS Migration work?
AWS Application Migration Service automates the conversion of your source servers to run natively on AWS, reducing time-consuming and error-prone manual processes. It also makes application modernization easier by including built-in post-launch optimization options.
What are the steps to migrate applications to the cloud?
The Steps for Migrating Applications to the Cloud: Step 1: Determine the Application's Cloud Readiness. Step 2: Do I Need to Update My Applications to Migrate to the Cloud? Step 3: Calculate the costs and weigh the benefits. Increasing Cloud Adoption Step 4: Select the Appropriate Cloud Environment Step 5: Choose the Best Cloud Service Provider and Make the Switch
What are the 3 main phases of cloud migration?
After determining that the cloud is the best option for addressing the business challenges you face (which may or may not be the case), there are three stages to moving to the cloud: planning, mid-shift, and go-live.
