MicroServices/Cloud Architect, Long Island City, NY

Responsibilities:

• Used APIGEE as a API Gateway to the APIs. Used for session propagation and OAuth token validation and generation with the Siteminder IDM. Created APIGEE proxies for converting SOAP to RESTful calls and service choreography.
• Use EventDriven Architecture with Event Sourcing
• Created computing and data resources on AWS using EC2. Installed Pivotal Cloud Foundry on EC2 to manage the containers created by PCF. Used Docker to virtualize deployment containers and push the code to EC2 cloud using PCF. Used SpringCloud Boot and Netflix OSS for microservices development.
• Functional Decomposition: Work with business analysts to functionally decompose business capabilities into a set of discrete microservices. A business capability and its set of business services are defined a priori by the business.
• Used Confidential and Confidential for designing Microservices.
• Maintaining strong cohesion within a single microservice whilst facilitating some degree of reusability
• Loosely coupled microservices.
• Conforming to the Markets Canonical data Model - All the exchanges to the downstream and upstream applications should comply to industry standards CDM eg. FixML and FpML.
• Create logical bundles to represent different functions of the microservices as follows:
• Controller - resolves as endpoint as entryway into the microservice API. Controllers could exist for any logical component of the microservice, i.e. for business logic, and visualization, and to a lesser extent data access.
• Channel - provides UI visualization and logic
• Service - where the business and application logic resides
• Persistence - for local CRUD operations
• Integration - where an external endpoint is accessed by the microservice (as a client)
• Domain - hold data objects (e.g. as beans)
• Mapper -- map one data structure to another
• Development Tools used:
• Spring Boot, Maven, Jenkins, GitHub, GemFire, REST API, Netflix OSS.
• Spring Cloud using pivotal cloud foundry for hybrid deployments.
• Eureka from Spring Cloud for dynamic microservices registry and discovery.
• Security - All service requests are proxied through the Platform Security Gateway (PSG). This is implemented using Spring Security framework.
• Spring Actuator for microservices health check and metrics.
