Abstract: Provided are methods and systems for transition between a current cloud-based code environment and an updated cloud-based code environment. A method for transition between a current cloud-based code environment and an updated cloud-based code may commence with generating a steering policy. The steering policy may include a set of rules to guide steering decisions between a current cloud-based code environment and an updated cloud-based code environment. The method may further include sending the steering policy to a steering server. The steering server may make steering decisions to steer, based on the steering policy, service requests between the current cloud-based code environment and the updated cloud-based code environment. The method may continue with receiving feedback concerning actual steering decisions made by the steering server. The method may further include automatically adjusting the steering policy in response to the feedback.

Abstract: Policy-driven management of application traffic is provided for services to cloud-based applications. A steering policy refers to a set of rules is generated for a deployment from a current code environment to one or more replicated code environment differing in some key respect. The steering policy can guide steering decisions between the current and updated code environments. A steering server uses the steering policy to make decisions about whether to send service requests to the current code environment or the updated code environment. Feedback concerning actual steering decisions made by the steering server is received (e.g., performance metrics). The steering policy is automatically adjusted in response to the feedback.

Abstract: An apparatus discerns clients by the requests made to a web application server through a web application firewall, which injects client side code into the responses with a randomized challenge that needs a unique answer to be returned in the cookie. The client side code generates cookies, which identify a browser to the web application server, or the web application firewall in subsequent requests if made by a normally configured browser and a fail threshold is checked for subsequent requests originating from such a browser. Each browser is thus fingerprinted and if the expected answer failures exceed a threshold, the client is marked as suspicious and a subsequent Turing test is enforced to these suspicious clients, failing which, a subsequent defined action is taken.
