Why this conversation mattered

Many enterprises still run mission-critical workloads on legacy platforms that weren’t designed for today’s security demands, user expectations, or scale. Big-bang rewrites are risky and expensive—but standing still is riskier. The session explored pragmatic ways to modernize: reinforcing what works, isolating what doesn’t, and introducing cloud-native capabilities that unlock agility now, not years from now.

Reality check: Your legacy systems won’t evolve on their own—but your competitors will.

Session highlights

1) Real-world modernization stories

We walked through projects where COBOL and Fortran systems were incrementally migrated to Java and .NET. Rather than switching everything at once, teams applied the strangler-fig pattern and anti-corruption layers to keep business running while new services came online. API gateways and message brokers allowed the old and new worlds to coexist with clear contracts and testable interfaces.

2) AI-assisted acceleration with Amazon Kiro

AI can shorten discovery and delivery cycles. With Amazon Kiro, teams can:

• Analyze legacy codebases to map dependencies and hotspots.
• Generate scaffolding, tests, and refactoring suggestions to reduce boilerplate.
• Speed up conversion and hardening so engineers focus on design and quality.

3) Security & compliance by design

Security isn’t an afterthought; it’s the runway. The webinar covered:

• Identity isolation (least privilege, SSO, short-lived credentials)
• Secrets management & encryption everywhere
• Threat detection & guardrails (policy-as-code, automated checks)
• Mapping controls to compliance requirements to shorten audits and reduce operational risk

4) Architectures that work now

• Containers & serverless for elasticity and cost efficiency
• Event-driven integration to decouple modules and scale independently
• Managed databases & data services to improve reliability without adding ops burden
• Observability first: central logging, metrics, and tracing with service-level objectives to make each release safer than the last

A simple, low-risk roadmap

1. Assess & prioritize
   Inventory domains, SLAs, dependencies, and pain points. Pick a single high-value slice—an API, report, or batch job—to pilot.
2. Establish guardrails
   Set up landing zones, identity boundaries, networking, cost controls, and observability.
3. Carve out and containerize
   Wrap the targeted capability with APIs; containerize where appropriate; introduce queues for long-running jobs.
4. Introduce cloud-native services
   Move specific functions to managed databases, serverless jobs, or event buses to remove bottlenecks.
5. Harden security & validate
   Bake in encryption, secrets rotation, and policy-as-code; test with contract suites and performance baselines.
6. Measure & scale
   Track latency, error rates, cost per transaction, and developer throughput. Expand the approach domain by domain.
