Serverless Migration to AWS by Firemind

Overview: A function moved without its triggers is a function that never runs. Serverless migrations fail on the wiring: bindings with no direct equivalent, workflows that hold state, and event sources that retry, order or time out differently on AWS. Built on Firemind's IT Operations Engine, this service runs the migration as governed code in your AWS account, and the same Engine runs each workload once it lands.

Four stages, contracted together or separately

• Assess. Discovery of every function, trigger, binding and workflow, with the behaviour differences each will meet on AWS. Aligned to the Assess phase of the AWS Migration Acceleration Program (MAP): a readiness assessment based on the AWS Cloud Adoption Framework, a migration path for every workload, a business case with an AWS Pricing Calculator estimate, and a wave plan.
• Mobilize. Landing zone readiness, detailed discovery and planning for the first waves, a pilot migration, and MAP tagging set up so migrated workloads are tracked from day one.
• Migrate. Functions moved to AWS Lambda, workflows to AWS Step Functions, event sources to Amazon EventBridge, Amazon SQS and Amazon SNS, and serverless containers to Amazon ECS on AWS Fargate, each deployed as infrastructure as code and checked by contract tests before cutover.
• Operate. The Engine runs the migrated workloads: monitoring, incident remediation, patching and decay management such as end-of-life runtimes, with high-risk changes held for a named approver. Each wave lands in operations the day it passes acceptance.

Validated and governed

Every wave starts with acceptance tests agreed with your team: functional checks, performance baselines and data comparisons wherever data moves. They run before and after cutover, and every wave has a tested rollback. The Engine plans each change, raises it as code and runs it under your change rules. Low-risk, reversible steps run automatically. Cutovers and other high-risk changes wait for a named approver. Every action is recorded in an immutable audit trail and in your own AWS CloudTrail.

What is in scope

• Function code changes for AWS Lambda handlers, SDKs and runtimes, raised as pull requests for your review
• Trigger and binding replacement, with contract tests for every event source
• Workflow migration from Durable Functions and similar to AWS Step Functions
• Infrastructure as code for every function, with AWS SAM, AWS CDK or Terraform
• Observability from day one with Amazon CloudWatch and AWS X-Ray

What stays out of scope

Rewriting functions in a new language stays out of scope unless agreed in the private offer. Low-code workflow products are listed and assessed, and their migration is scoped separately with you.

AWS programmes: Firemind holds the AWS Migration and Modernization Competency. Eligible migrations may qualify for MAP funding, and Firemind prepares the MAP documentation with your AWS account team. Eligibility and funding are confirmed by AWS.

How it starts: After the private offer is accepted, you grant read-only access to the clouds that run your functions and, optionally, your source control and deploy an IAM role in your AWS account using AWS CloudFormation. A full description of the role and its policy statements is provided before deployment. The Engine uses temporary credentials, and every action is recorded in your own AWS CloudTrail. Scope, acceptance tests and named approvers are agreed at the start of each stage.

Deployment: Pilot scopes run from Firemind's AWS environment. In production the Engine runs inside your own AWS accounts. Running the Engine, and the migrated workloads, may incur AWS infrastructure charges, for example Amazon Bedrock, compute and storage. These are billed separately from this AWS Marketplace transaction and are your responsibility.

Pricing: Delivered through an AWS Marketplace private offer, scoped to your estate. The four stages can be contracted together or separately. Contact hello@firemind.com  to scope.
