A viagem invisível do dinheiro até o mainframe e o COBOL
Fortress at the Edge: WAF and API Gateway
Upon entering the bank's network, your transaction first encounters a Web Application Firewall (WAF) for security, filtering malicious traffic. It then proceeds to the API Gateway, which authenticates the request and routes it to the appropriate internal system. This layered approach ensures security and efficient processing before the transaction delves deeper into the bank's core systems.
The Heartbeat: CICS and COBOL on the Mainframe
Within the mainframe, CICS acts as the transaction monitor, managing incoming requests and dispatching them to business logic programs, typically written in COBOL. These COBOL programs execute the core business rules, potentially interacting with other systems like IBM MQ for interbank communication, ultimately processing the financial transfer. This highlights the enduring role of COBOL and mainframe architecture in critical financial operations.
The Talent Gap: A Bridge to COBOL Careers
A significant gap exists in the market for professionals skilled in mainframe technologies like ZOS, CICS, COBOL, and DB2. While many developers understand modern systems, they lack experience with these foundational, decades-old technologies. This scarcity presents a unique opportunity for developers to enhance their career prospects by acquiring expertise in these in-demand, legacy systems.
