Application modernization
Your applications weren’t built for what your business needs now or where it’s going next. Slalom helps untangle the monolith and modernize with precision, turning rigid architectures into modular, scalable systems.
Data modernization
Your data is doing the work, but your platform is holding it back. Slalom supports the modernization of your data stack with scalable, AI-ready infrastructure that can help reduce cost, improve trust, and unlock near real-time insight.
Mainframe modernization
Your mainframe earned its place. Now it’s time to replace it with something built for what’s next. Slalom helps you transition critical workloads with AI-assisted tools and a phased, low-risk approach.
Legacy modernization
Your legacy systems did their job—and then some. But they weren’t built for today’s speed, security, or scale. Slalom helps you modernize with clarity and control, using AI-assisted tools and phased delivery to reduce risk while accelerating results.
Legacy technology costs more than just budget. It’s costing you momentum.
Modernization isn’t about throwing everything out—it’s about building on what still works. It’s modernization with a mission: reduce risk, increase agility, and free up your teams to build what’s next.
Slalom’s legacy modernization solutions help you move from maintenance to momentum—with clarity, control, and no unnecessary overhaul.
Results may vary depending on project scope and organizational readiness.
