The IBM OpenWhisk serverless architecture accelerates development as a set of small, distinct, and independent actions. By abstracting away infrastructure, OpenWhisk frees members of small teams to rapidly work on different pieces of code simultaneously, keeping the overall focus on creating user experiences customers want. Google Cloud Functions Beta is a serverless environment to build and connect cloud services. Incorrect Answers:A, C: AWS Lambda is serverless computing framework, but AWS EC2 and AWS Blueshift are not.Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. AWS Blueshift is a standalone service written in Clojure (a dialect of Lisp that targets the JVM) that is expected to be deployed on a server. It is configured to watch an S3 bucket; when it detects new data files and a corresponding Blueshift manifest it will perform an upsert transaction for all the files with the additional benefit of being a single import for a large number of files. References:https://www.ibm.com/cloud-computing/bluemix/openwhiskhttps://cloud.google.com/functions/

The required fields of a CSR are Common Name (URL), Country, City/Locality, State /Province, Organization Mae, Organization Unit, and Legacy ID. References: https://knowledge.rapidssl.com/support/ssl-certificate-support/index?page=content&actp=CROSSLINK&id=SO16317

As the application fails to start the most likely cause of the problem is that the application does not have enough memory. Note: Receiving an OutOfMemoryError normally means one of two things:You heap size is not large enough for the memory requirement of the application. You have a memory leak The quickest thing to try would be to increase the memory allowance for your application, which will also increase the Java heap size for you. You can do this using a "memory" entry in the manifest.yml. For the second, you really need to generate a heapdump so that you can analyse the problem using Memory Analyzer. References: https://developer.ibm.com/answers/questions/29036/out-of-memory-error-on-bluemix-app.html

B: Although you can use the entities in a package directly, you might find yourself passing the same parameters to the action every time. You can simplify the process by binding to a package and specifying default parameters, which are inherited by the actions in the package. Example: Bind to the /whisk.system/samples package and set a default place parameter value.wsk package bind /whisk.system/samples valhallaSamples --param place Valhalla ok: created binding valhallaSamplesC:  Several packages are registered with Cloud Functions. You can get a list of packages in a namespace, list the entities in a package, and get a description of the individual entities in a package. Example: Get a list of packages in the /whisk.system namespace.wsk package list /whisk.system Note: Using the Cloud Functions CLIOnce the environment is configured, you can use the Cloud Functions CLI to perform the following tasks:Run your code snippets, or actions, on Cloud Functions Use triggers and rules to enable your actions to respond to events. Learn how packages bundle actions and configure external events sources. Explore the catalog of packages and enhance your applications with external services, such as a Cloudant event source. References: https://console.bluemix.net/docs/openwhisk/openwhisk_packages.html#openwhisk_packages

A toolchain is a set of tool integrations that support development, deployment, and operations tasks. References: https://www.ibm.com/devops/method/category/tools/

B: The third-party service BlazeMeter is a load and performance testing platform that offers a cross-enterprise test automation framework for the entire technical team throughout the product development lifecycle. Developers, DevOps, Ops and QA Engineers can run Continuous or “On Demand” testing for APIs, mobile apps and websites. BlazeMeter can be used in the cloud, on-premise or as a hybrid solution. It is compatible with Apache JMeter and Selenium and integrates with CI, CD, and APM tools. D: The third-party service Load Impact helps developers test their code at scale by harnessing the power of cloud-based testing to generate loads on their web applications from multiple geographical regions. References:https://console.bluemix.net/catalog/services/blazemeter?env_id=ibm:yp:us-southhttps://console.bluemix.net/catalog/services/load-impact?env_id=ibm:yp:us-south

IBM Cloud Data Encryption Services (ICDES) is a software-defined data protection solution that can be run in any public or private data center. ICDES is included in IBM SoftLayer®, IBM’s Infrastructure as a Service solution. ICDES provide data-storage encryption capabilities with availability and fault tolerance to meet enterprise encryption requirements for data at rest. Incorrect Answers:C: IBM Guardium provides integrated data classification capabilities and a seamless approach to finding, classifying, and protecting your most critical data, whether in the cloud or in the data center. D: SSL is used to protect data in motion, not to protect data at rest.References: https://developer.ibm.com/cloudarchitecture/docs/security/securing-workloads-ibm-cloud/data/#ICDES

Session Cache: When bound to a program, this service enables persistence for all sessions across multiple instances of the application. In the event of a failure, sessions are seamlessly recovered. References: https://www.ibm.com/developerworks/cloud/library/cl-cloudtrader-app/index.html

Session Cache provides a NoSQL style distributed key-value storage service and provides the following features:Low latency data access Dynamic scalability of both data and transactional capacity Transactional semantics Data replication to prevent data loss during system outages Integrated web console to monitor service instance performance and usage References: https://console.bluemix.net/docs/services/SessionCache/index.html#session_cache
