Modernize faster: rearchitect, replatform, refactor

Instant intelligence means no more surveys and discovery calls

“58% of developer time is spent understanding existing code structures.”

IEEE, Measuring Program Comprehension

The challenge

From mainframe modernization to cloud refactoring, understanding the internal mechanics of ‘black box’ applications is crucial for success. Architects often spend months analyzing the code, while teams keep hopping from call to call trying to connect the dots. Progress is made an inch at a time. Wrong turns and dead ends are all too common.

Enter CAST

CAST cuts months of work to minutes by mapping all application elements and interactions into a living knowledge base. By applying semantic analysis, CAST reverse-engineers all internal dependencies, revealing how applications work. From database structures and code components to transaction flows and framework dependencies, team members can instantly see every detail across all layers.

“We could jumpstart our current projects and also accelerate the onboarding of new engineers.”

Doug Criddle
Sr. Director of Engineering, PMMC

See it all

  • Explore the actual internal architecture in real time.
  • Find artifacts contributing to functional communities.
  • Detect obsolete technologies for decommissioning.
  • Identify candidates for decoupling.
  • Uncover microservices opportunities - components supporting multiple functions.
  • Recognize tightly coupled communities with low modularity, as well as those with low coupling that can be easily isolated.

Monitor architectural impact

  • Assess the impact of new or changed code.
  • Ensure adherence to intended designs.
  • Evaluate effects on a system’s structural quality.
  • Determine the impact of breaking off an application from its cluster.
Monitor architectural impact

Trace pathways in a flash

  • Plot data access graphs, including all components involved in data display and processing.
  • Reverse engineer API call graphs, highlighting routes with hard-to-separate dependencies and flows with low dependencies.

Collaborate in context

  • Tag components using functional knowledge from application users.
  • Tag modules by function and relevance, such as those comprising a transaction or slated for decoupling.
