Efficient Data Center Exit with AWS Cloud Migration Solutions

Client Overview

Oakcrest Technologies worked with a small-to-medium business (SMB) who was trying to retire their on-premise data centre and migrate it to the AWS Cloud. This case illustrates how specialized cloud migration solutions can ensure a seamless migration without compromising the application. With proven methodologies and tools, Oakcrest Technologies delivered a migration that allowed the client to scale their operation more effectively.

Business Challenge

This client needed to exit their data centre in a limited amount of time, and the critical applications should continue to run. They required custom data migration services for SMEs to set up a scalable and secure cloud environment for future growth and performance. They also needed economical alternatives that wouldn’t have cost the business of running on-premises hardware or have risk of data migration.

Solution Approach

1. Assessment and Planning:

Analyzed the existing infrastructure and application dependencies thoroughly. That meant determining where the bottlenecks were and if the client was ready for migration.
Created a customized migration plan, based on lift-and-shift to speed things up and eliminate change. This made it possible for the client to be in operational continuity during the migration.
Created a roadmap that lays out milestones and timelines to keep things transparent and in line with the business objectives of the client.

2. AWS Infrastructure Design:

Created a safe AWS network with the right network division like public and private subnets for security and speed.
Set Amazon EC2 instances to match client’s existing on-premises hardware requirements for compatibility and migration.
Used AWS cloud migration tools such as Amazon S3 for application data and archives storage providing the client with a scaled and secure way to store large amounts of data.

3. Secure Connectivity:

Configure a site-to-site VPN for safe data movement between the current data center and AWS while keeping data private and secure during the migration.
Used AWS Database Migration Service (DMS) to real-time replicate database for data integrity while migrating. This was to permit the client to operate unimpeded.
Encryption of sensitive data while transporting and storing it in AWS environment.

4. Application Migration and Testing:

We implemented the Blue-green deployment process to test applications thoroughly in a new environment before complete switchover. This shortened downtime and prevented application failure risks.
Configured sandbox URLs for client team to test application functionality and not affect real time, making the move seamless for end users.
Ran intensive testing on performance to ensure that applications were stable and performant in the AWS platform.

5. Failover and Validation:

Installed reverse replication as an emergency during post-migration stabilization period for data integrity and system availability. This was another way to secure the client.
Conducted full validation tests to make sure all the migrated applications and services were working correctly in the new environment.
Developed robust documentation and training for the client’s IT team so they could be empowered to implement the new infrastructure.

Business Benefits

Timely Data Center Exit: Decommission the in-house data center in time, with no added costs and penalties for additional operational costs and penalties.
Low Downtime: Retained near zero downtime of critical applications, and kept business running throughout the migration. This was to guarantee the customer’s customers and stakeholders did not suffer.
Enhanced Scalability and Security: Delivered a fully scalable AWS infrastructure that can scale with the growth of the client and better security to secure data. It also puts the client on a long-term winning footing in a market.
Cost Efficiency: Reduced operating expenses with cloud migration managed services, reduce the cost of storing physical hardware and use AWS’s economical pricing.
Future-Intelligent Platform: The migration enabled the client to use the power of AWS services and tools to innovate and operate more efficiently.
