Hello, everyone. Welcome to join Alibaba Cloud ACA System Operator Certification Training. In this training, we will introduced Alibaba Cloud Profession and Certification from Walk first, then we will give you more details about ACA system operator exam outline, and the objective of this preparation training. Last but not least, we will give you an overview for other related products and the solutions. Here is our role-based Professional Certification framework. We have three different levers, ACA for Associate, ACP for professional, ACE for expert level. We also provide the different certifications for different genres based on your different technical background. In ACA level, we have a developer's education, system operators education, Cloud computing architect to security architect, Big Data Architect and Cloud Native Architecture certifications. In this training, we will focus on system operator certification, we'll introduce a certification outline and the related products and solutions. Let's take a look of the operators certification exam outline first. The ACA system operators certification exam will cover seven different domains. First one is high availability and fault tolerance. The exam taker should be able to deploy highly available and the disaster recovery solutions on the Cloud. The second one is Cloud Infrastructure deployment and provisioning. The exam taker should be able to deploy and configure their Cloud infrastructure, and they should be able to deploy their applications directly with Alibaba Cloud Function computer server-less workflow, and API Gateway. Next domain is data management and the security. The exam taker should know how to select different type herself for database, for different application scenarios to migrate data from a local environment to Object Storage Service or relational database service. Then the next the domain is networking. The exam taker should apply Alibaba Cloud Networking futures to implement connectivities and to view their full mashed global network. The next one is the Cloud governance. The system operator should manage the identity and authentication for an organization on the Cloud. This should be able to use Action Tree Cloud config to do the audit and compliance and to enable finance to see what has been spanned, when and by whom. The next topic is Cloud monitoring and alarming. By using Cloud monitor to monitor the application resources, and the alarm should be automatically triggered when some incidents happen in your system. The last two domain is automation and orchestration. The system operator should leverage the outer region to [inaudible] or Alibaba Cloud OS server-less workflow in order to reduce the operational workload to automate manual and repeatable process. That's it for the domain we should cover for the system operator certifications. In this certification exam, we will have 50 questions. There are 30 question of single choice question, and the 10 multiple choice question, 10 true or false question, and you will see the questions regarding all the seven domains we've mentioned before and you need to have a 60s points to pass the certification exam. In the next section, let's take a look of the operators certification objective. ACA system operator certification is intended for individuals who have technical expertise in deployment, management, and operations on Alibaba Cloud. The exam taker should be capable for deploying, managing, and operating scalable, highly available system on the Cloud. Also, they should be capable to selecting appropriate service on Alibaba Cloud and then knowing how to monitor the back and do the troubleshooting. They should apply Alibaba Cloud operation best practice, and then migrating their on-premise workload to the Cloud and managing IT governance on the Cloud. In the last section, let's go through all the related products and solutions. In ACA system operators certification, we will cover seven domains. Firstly is the Cloud architecture, high availability, and the fault tolerance. The exam-taker should be capable to implement scalability and elasticity based on the given used case using autoscaling and load balancer. They also need to recognize and to differentiate highly available anti-resonance architectures on Alibaba Cloud. This should be able to leverage their relevant Cloud service such as SLB doing as global traffic Manager to implement highly available or disaster recovery system on Alibaba Cloud. The second domain is Cloud infrastructure deployment and provisioning. The exam-taker should be able to deploy and configure ECS on Alibaba Cloud setup to remote access to ECS. Also, be able to create an ECS image to package applications and runtime environment for easy distribution. They also should be able to create container image for lightweight application packaging using Docker to publish container images to Alibaba Cloud Container Registry, run containers using Alibaba Cloud Elastic Container Instance for the serverless container deployment. They should be able to deploy applications directly with Alibaba Cloud Function Compute, such as workflow and API Gateway. Finally, to identify and do the troubleshooting for all the deployment issues. The third domain is data management and security. The exam-taker should know how to select different types of storage service like NAS, Cloud Disk object storage service, or even database service for all your different application scenarios. They should be able to migrate data from a local environment, to OSS, RDS using DTS or OSS utilities. They have to identify implement data protection, encryption, and the capacity planning needs. Finally, they should be able to implement data backup, archiving, and retention for Cloud Disk, RDS, and OSS. The next domain is networking on cloud. The exam-taker should apply Alibaba Cloud networking features to implement the connectivities, to build a full mesh to go over network on the Cloud. They should also know the network design for resource sharing between different accounts, network security solutions, and also gather and interpret relevant information for network troubleshooting. The next domain is Cloud governance. The exam takers should be able to manage identity and authentication for an organization's user accounts, multi-platforms. To manage permissions for an enterprise organization on the Cloud, use ActionTrail for audit to see what actions were taken, when and by whom. Allow technical staff to perform after-the-fact analysis, to pinpoint weaknesses that led to security breaches or breakdowns. They should be able to enable finance to see what's being spent when and by whom, and also do cost optimization as well. The next topic is Cloud monitoring and alerting. Use Cloud monitor to monitor application resources usage in the health states. Implement autoscaling routes, including scheduled autoscaling and even triggered autoscaling. Use Cloud config to track resource configuration changes and evaluate the configuration compliance. In case of the conflict with the compliance, the system should be able to send the alarm. The last domain is automation and orchestration. The exam-taker should be able to use Alibaba Cloud service, and features to manage and assess its resource utilization. They should leverage different tools like a terraform or Alibaba Cloud resource orchestration service, operation orchestration service, or serverless workflow in order to automate manual or repeat bar process to minimize operational workload. Thank you for watching this chapter. See you in the next section.
