Application Migration to the AWS
The cost of application migration to AWS varies according to the size of the application.
For a small app, medium/large app migration to AWS, the cost will be $5000-$15000 and $20000-$250000 respectively.
In order to maintain transparency and no error in migration, Livyoung Realtech Enterprise suggests an iterative form of migration to AWS.
As far as the time is concerned, the standard iteration often takes two to two months.

Steps to Migrate Applications to AWS
We at Livyoung Realtech Enterprise follow the below mentioned steps in order to smoothly migrate apps to AWS:
1. AWS migration prerequisites gathering and high-level planning
Before migration to AWS prepare a list of your reasons as to why such migration is significant and thereafter determine the scope of the AWS migration.
Later, you can choose the best migration approach such as rehost, refactor, re-architect, and rebuild, or a combination of it, for your app depending on the migration needs and objectives.
Ensure that your cloud migration plan incorporates all the vital app elements and define cloud app deployment tooling along with assessing the compatibility, and scalability of the workloads with AWS.
Lastly, outline the business outcomes, risks involved, and costs required to successfully migrate apps to AWS.
2. AWS migration design and planning
Find out migration project stakeholders, migration order for workloads, team roles, and which deployment model will suit you.
Figure out app refactoring activities, business owner (for enterprise software), and build an app migration prioritization framework and app dependencies for various reasons.
Schedule your app migration and identify the right fit for AWS services such as compute, storage, analytics, continuous integration, delivery, and deployment.
3. Business case AWS migration project roadmap
Set up monitoring and analytics tools such as AWS Monitor, AWS Advisor, AWS Log Analytics, and more, and monitor the functionality and performance of migrated apps.
Keep a check on app changes and update the configuration after migrating to AWS, together with improving security and performance levels.
Estimate ROI and business benefits of the migration to AWS and fill up the projected gap, if any.
4. Data migration
Before migrating the data, the migration team checks the quality of it as to whether it’s valid and develops a tool or scripts to extract, clean, and load data into the AWS database and automate data migration.
Validate the trial and check for data losses or the overall outcome of the data migration process.
5. Perform pilot AWS migration (optional)
As per the plan, the team will set up a beta environment, and then a part of the app functionality will be tested (using test data and test database) and replicated to run in AWS.
Analyze the outcome of such migration and if required, adjust the application architecture along with the configuration of cloud infrastructure.
6. Iterative AWS migration and testing
Schedule and convey app downtime to whoever is concerned and set up a new AWS production environment and DevOps tools and processes.
Transfer the most essential workloads and their data to AWS, confirm whether the migration activities are not affecting apps’ functionality, and be ready with backup and disaster recovery solutions.

Sourcing Models for an AWS Migration Project
The followings are the sourcing models for an AWS Migration project that will help you in figuring out the best for your business:
In-house team
Pros
Full control over the app migration process. Ensure team productivity.
Cons
Lack of certain essential resources. Hiring is essential yet costly. Suffer with a lot of burden and lose focus on other core business affairs.
Partial Outsourcing
Pros
Fast project ramp-up. Limited utilization of resource. Exposure to wide AWS and migration expertise.
Possibility of partial team coordination.
Full Outsourcing
Pros
Share the burden with a vendor that takes full responsibility. Fully established AWS migration frameworks. Get access to AWS discounts and services.
Higher risk involved as far as migration or modernization is concerned.
A mix of an in-house team and outsourced consultancy
In-house team being aware about the current software environment and access the assets easily. Outsourced team will offer expert guidance on every matter and fills up the gap, if any.
Risk involved in consultancy team selection. Require much time to set up the relationship between the two
