My Alibaba Cloud ACE Experience: Part 2

Alibaba Cloud Knowledge

  • Familiarity with basic concepts of Alibaba Cloud computing products, including Elastic Compute Service (ECS), Server Load Balancer (SLB), Auto Scaling, Object Storage Service (OSS), Content Distribution Network (CDN), Virtual Private Cloud (VPC), Alibaba Cloud Security, and CloudMonitor. It is an essential requirement, and in my perspective, it will be useful if you read more about ECS, SLB, Auto Scaling, CDN, VPC, RDS (DRDS), OSS, Big Data, Migration and Hybrid Cloud, Security & Access Control, Middleware, and IoT.
  • Understanding of main application scenarios of Alibaba Cloud computing products, and scenarios where the products are applied in a combination. Thorough knowledge of ECS and its related concepts, including the snapshot, backup policy, security group, disk encryption, and RAM instance role, is essential.
  • Grasp of fundamental operations of Alibaba Cloud computing products, such as provisioning, creation, configuration, starting, stopping, and deletion, is a must-have. Understanding the design and deployment of scalable system architectures and familiarity with self-healing technology, fault tolerance service, disaster recovery, and failover policy helps you prepare for the exam better. All these requirements together give a better understanding of the solution architecture. Since the exam questions are scenario-based, it’s critical to understand the key concepts, including auto-scaling, SLB, high availability (HA), and disaster recovery, as they play a significant role in architecture design.
  • Understanding of Alibaba Cloud’s big data products, including big data analysis and presentation, big data basic service, big data application service, and analysis and search service, is essential. Strong knowledge of MaxCompute, DataWorks, DataV, MapReduce, QuickBI, and PAI will place you in a better position to pass the exam.
  • Familiarity with Alibaba Cloud’s security features and best practices is imperative. Understanding of services such as Anti-DDoS, Anti-DDos Basic (free, 5G), WAF, SSL Certificates, and KMS is helpful while attempting security related questions.
  • An in-depth understanding of Alibaba Cloud-related network technologies, including DNS, SLB, VPC, NAT, VPN gateway, and Express Connect, helps tackle complex scenario-based questions. I recommend practical exercises such as building ECS as per different configurations and testing for a clear understanding of the concepts. Usually, questions are based on multinational corporation communication use-case scenarios. You need to choose the right service, such as DNS, Express connect, and VPN Gateway, along with RDS, ECS, and other services. Therefore, practical exercises are critical for exam preparation.
  • Skills in applying Alibaba Cloud storage technologies, including Cloud Disk, OSS, and NAS will be useful in overall preparation. You must learn about OSS and its tools such as ossbrowser, ossutil , ossimport, ossftp,ossfsand, and some simple API commands.
  • Understanding of Alibaba Cloud database technologies and the related methods that can be replicated like RDS, DRDS, Table Store, etc. is essential from the exam standpoint. You must know the RDS function, read-only instances, white list, TDE.
  • Grasp of application migration to Alibaba Cloud is also crucial for exam preparation.
  • The skilled application of Alibaba Cloud ROS and an in-depth understanding of RAM is another important requirement. Resource orchestration service (ROS) is the future of application development. You must have basic knowledge about four aspects, deployment efficiency improvement, flexible resource management, convenient architecture optimization, and compliance control.
  • An in-depth understanding of Alibaba Cloud middleware technologies, such as EDAS and MQ, is another critical element of the ACE exam’s knowledge requirements.

Conventional IT Knowledge

  • Basic understanding of general cloud computing concepts and knowledge of virtualization, storage, networks, and other related concepts.
  • Knowledge of the typical web application architecture, including web servers, application servers, server load balancers, and databases.
  • Experience in CDN application.
  • Understanding of standard network protocols such as HTTP, FTP, TCP, UDP, and ICMP, etc.
  • Network-related knowledge including routing, switching, routing tables, NAT, DNS, HTTP, DNS, TCP/IP, and OSI model, etc.
  • Familiarity with the software development lifecycle.
  • Understanding of multiple software development models, RESTful web service, XML, and JSON, etc.
  • Knowledge of large-scale distributed system architecture.
  • Familiarity with relational and non-relational databases.
  • Understanding of network security fundamentals, such as firewall policies, key encryption, access control, network security, and network attack and protection.
  • Understanding of information and application security concepts, including public-key encryption, remote access, access credentials, and certificate-based authorization.
